In the Programming with the Windows API chapter of our Excel VBA. Programmers Reference, we approached the subject of using Windows API calls by. This tutorial attempts to get you started developing with the Win32 API as quickly The translation and PDF versions are unfortunately difficult to update, and are. the PDF file, you can use the pdfdetach tool including in the poppler suite, Some PDF viewers may also let you save 3 C and Win32 API.
However, for the purpose of this project, we will leave options as they are. Click on Finish to both complete and close project configuration wizard. Very often, programmers may want to use shortcuts to avoid navigation through menus in order to use a particular feature. Build Solution can be done as well by pressing shortcut key F7. From the Solution Explorer, right-click on the solution, wintutorials in this case, and then select Build Solution. Note: To build the entire solution will build all projects associated to it.
If you wish to on;y build a single project, then rick click on the project, introduction in this case, and select build. By default, once a build has started, Visual Studio will automaticaly switch to the Output Window so that you may see the progression of the build. Assuming that no code modification was made, the build should be successful. Step 4. Control the priority class of the PDF processes. Limited support for PStill converter was added.
Debugging feature named BugRadar was added. CustomGui setting now holds a command line instead of only the executable. Many translations were updated. Now supports re-distilling of encrypted PDF documents. This requires that you are the owner of the content. Multiple option sets can now be defined. This enables you to select between sets of preconfigured settings when you create your PDF documents. Append to the output file if it already exists.
Support for 64 bit Ghostscript 9. Better cleanup during uninstall. Advanced customization feature where you can replace the GUI with your own executable file made in your favorite programming language. Fix for background syntax. Support for custom license agreements.
Support for pdftk in superimpose operations. Lists only local printers when running the options dialog. Mapped printers are not shown in Citrix and Terminal Server sessions. Macros can abort the process by setting the Abort to true in the context dictionary.
In-place editing of OLE objects is recommended, if at all possible. Must not add information to the WIN. INI files. Some exceptions may apply to this rule when it is unavoidable. The application must run successfully on both Windows 95 and Windows NT, unless architectural differences between the two operating systems prevent it. It is also strongly recommended that file extensions not be displayed. An application does not need to meet all of these requirements to execute under Windows 95, but it must meet each one to be considered for the Designed for Windows 95 logo.
Windows 3. Most Windows 3. When Microsoft released Windows NT 4 with its new user interface to match Windows 95, they also introduced a new logo that indicates that the software runs equally well under Windows NT 4 and Windows Some of the exemptions have been made requirements now that the APIs are more in sync with each other. Other issues deal with Internet awareness and the requirements for distributing software over the Internet.
However, all guidelines should be followed as closely as possible to produce an application that provides the end user with a common look and feel under Windows 95 and Windows NT 4. Windows A user typically interacts with data objects using two different types of windows, a primary window and secondary windows.
The primary window is where most of the viewing and editing takes place, whereas secondary windows allow the user to specify options or provide specific details about the objects in the primary window. Secondary windows are usually property sheets or dialog boxes.
Window Components A typical primary window, shown in Figure , consists of a frame, client area, and a title bar. If the content of the window exceeds the viewable area, scroll bars are used to give the user the ability to scroll the window.
The window can include other components, such as menu bars and status bars. Figure Primary window components Every window has a window frame that defines the shape of the window.
A sizable window, as shown in Figure , has a border that provides points for resizing the window, such as the grip and close window button. If the window cannot be resized, the border does not have the extra width of the sizable window. Title Bar The title bar or caption extends the width of the window along the top edge inside the border.
The title bar identifies what the window shows and lets the user perform many window operations as well. It is the control point for moving the window and the location of the system menu, minimize, maximize, and restore buttons, and the close window button. The user can access the system menu of the application by pressing the left mouse button on the small key combination, or icon of the application, pressing the pressing the right mouse button on the title bar.
If the application includes a specifier, it should include a dash and the specification text.
For example, the Windows Explorer indicates which container it is exploring. See the System Integration section later in this chapter for information on how to register icons for an application and data file types.
If a data object does not currently have a name, create one automatically by using the short name, such as Document. If it is not practical to supply a default name, use the placeholder Untitled in the title bar text. Figure Multiple-document interface maximized title bar Command buttons associated with the window appear on the right of the title bar. Table shows the primary buttons and the actions they perform. Minimizes the window. Maximizes the window. Restores the window. Previous Table of Contents Next Window Operations The basic operations that a user can perform on a window include activation, deactivation, opening, closing, moving, sizing, scrolling, and splitting.
All windows perform these operations in the same manner, which allows users to operate windows consistently throughout their applications. Activating Windows Even though users can display multiple windows at the same time, most users work with a single window at a time, the active window. The active window is distinguished from other windows by its title bar and window frame color.
Inactive windows use the inactive title bar and frame color. These colors can be set by the user and are dynamic. When a window becomes inactive, the application should hide the selection within the window to prevent confusion over which window is receiving keyboard input.
An exception to this would be a drag-and-drop operation when the cursor is over the inactive window. Opening and Closing Windows When the user opens a primary window, an entry should be created on the taskbar.
All open primary windows should have an entry on the taskbar to allow the user to easily switch between open applications. When an application is opened for the first time, use a reasonable default size and position. If the user opens an application that has been opened previously, restore it to its previous size and position.
If appropriate, restore the user interface settings, such as selection state, scroll position, and other related view information.
If the user attempts to open an application that is already running, follow the recommendations in Table Table Actions for already open windows File Type Action Document or data file Activate the existing window of the object and display it at the top of the window Z order the order in which the windows are stacked on top of each other. Application file Display a message box indicating that an open window of that application already exists and offer the user the option to switch to the open window or to open another window.
Either choice activates the selected window and brings it to the top of the window Z order. Document file that is already Activate the existing window of the file. Document file that is not Create a new MDI child window for the already open, but its associated associated file, place it at the top of the Z MDI application is already order with the MDI parent window, and running place the MDI parent window at the top of the Z order. When the user closes a primary window, close all dependent secondary windows and remove the taskbar entry as well.
For most applications, when the user closes the primary window, the application is closed. However, some applications, such as the printer queue, do not terminate when the user closes the primary window.
Before closing the primary window, display a message asking the user whether to save or discard any changes or cancel the close operation. This gives the user control over any pending transactions that are not saved. If there are no unsaved transactions, close the window without prompting the user. Typically, when a window is moved, the outline representation of the window moves as the user moves the window.
The window is updated when the move operation is completed.
On some systems, the window can be redrawn dynamically while the window is being moved. Applications should not prohibit the redrawing of the window while it is moving. The painting should also be as efficient as possible to provide a smooth appearance while the user is moving the window.
After choosing the Move command, the user can move the window with the key to end the keyboard by using the arrow keys and pressing the move and establish the new window position. Pressing aborts the move operation and keeps the window in its previous position. The application should not allow the user to move the window to a location from which it cannot be accessed. Previous Table of Contents Next Resizing Windows All primary windows should be made with resizable frames unless the information displayed is fixed, such as in the Windows Calculator program.
Users have several methods to size a window: the sizing frame, the minimize and maximize operations, restore, and the size grip. Application windows that allow sizing should normally implement all of these.
At the minimum, windows should implement the minimize and restore operations. With windows that have sizing borders, the user can size the window by dragging the border with a pointing device. Normally, as the user sizes the window, an outline representation of the window moves with the pointer. On some systems, the window can be redrawn dynamically while the window is being sized. The same rules apply here that apply to moving a window—the drawing should not be prohibited and it should be as efficient as possible.
The user can use the keyboard by selecting the Size command and using the arrow key accepts the new window size, and keys to size the window. The the key aborts the size operation. The maximize operation, as its name implies, sizes a window to its maximum size.
This size is the display size excluding the space used by the taskbar. Applications should not use a fixed display size, but should adapt to the shape and size defined by the system. Use a standard system function, such as the SetWindowPlacement function, which will automatically place the window correctly. Windows 95 and Windows NT 4 use a representation of minimized windows that is different from the one Windows 3.
When an application is minimized in Windows 95, the application is represented in the taskbar. For MDI child windows, the window is minimized within the parent window.
When a window is minimized, the Minimize command is disabled and the Restore command is enabled. When a maximized window is restored, the restore command button is replaced with the maximize command button on the title bar.
A size grip is a special handle, shown in Figure , for sizing a window in both the horizontal and vertical directions at the same time. To use a size grip, the user drags the grip with the pointing device, and the window resizes in the same manner as when the sizing border is used.
The size grip should always be located at the intersection of the horizontal and vertical scroll bars or the lower-right corner of the window. If the window has a status bar, the size grip is located at the right edge of the status bar. A window can have only one size grip at a time. Scrolling Windows When a window is too small to completely display a data object, the window should support scrolling.
This enables the user to move the view of the window to see other portions of the data object. The application should use a scroll bar a rectangular control that contains scroll arrows , a scroll box thumb , and a scroll bar shaft, shown in Figure A window can include a vertical scroll bar, such as the one shown in Figure , a horizontal scroll bar, or both, depending on the data object that is being viewed. If the data object is too wide, a horizontal scroll bar is appropriate.
If it is too high, a vertical one is used. However, if a window that has a scroll bar is sized so that it no longer requires one, continue to display it.
Consistently displaying scroll bars will result in a neater appearance. Arrows appear at each end of a scroll bar and point in the direction the window or view is moved. When the user selects an arrow, the window is moved one scroll unit in the direction of the arrow. The scroll unit is an application-defined unit of measure that is appropriate for the data object the window is displaying.
For example, a text file would scroll one line at a time when a scroll arrow is selected, whereas a picture would move a small number of pixels. The scroll unit should remain the same throughout the scrolling range. When a window cannot be scrolled any farther in a direction, disable the scrolling arrow corresponding to that direction. The scroll box or thumb moves along the scroll bar to indicate the approximate location in the data object the window is currently displaying.
For example, if the window is currently displaying the beginning of the data object, the scroll box is at the top of the scroll bar.
Re: How to print a PDF file using Win32 API
If it is displaying the middle of the data object, the scroll box is halfway down the scroll bar. The scroll box has changed in Windows 95 from previous versions of Windows. It is now proportionally sized to the amount of the data object viewed in the window and the total size of the data object. For example, if the window can display the entire contents of the data object, the scroll box is sized the entire length of the scroll bar.
Step-by-Step Guide to Building a Win32 API Application: Part 1
If the window can display half of the data object, the scroll box will be half the size of the scroll bar. The scroll box also serves another function: The user can drag the scroll box to scroll to approximate locations within the data object.
The scroll bar shaft also serves as part of the scrolling interface. When the user selects the scroll bar shaft with a pointing device, the window is scrolled the equivalent size of the visible area.
The direction of the scroll depends on which side of the scroll box the scroll shaft was selected. For example, if the user selects the scroll shaft below the scroll box on a vertical scroll bar, the window will scroll down. When scrolling with the scroll shaft, the application should leave a small portion of the data object visible from the previous screen.
For example, if the window is viewing a text file and the user scrolls down, the line that is visible at the bottom of the window becomes the line visible at the top of the window after the scroll is complete. Sometimes a window should automatically scroll. The amount of the scroll depends upon the application context.
For example, when a user generates a new line of text that is being typed in the window, it should scroll one line at a time. When scrolling horizontally, the scroll unit should be greater than the width of a single character to prevent scrolling continuously. Also, when the user transfers a graph object near the edge of the window, the scroll unit is based on the size of the object. Another example is an entry form—the window should scroll to follow the cursor as it moves to fields that are not displayed in the current view of the window.
An application should also use the navigation keys to support scrolling with the keyboard. If the window contains a cursor, such as in a text editor, and the user presses a navigation key next to the edge of the window, the window scrolls in the corresponding direction. Windows that do not contain a cursor, such as a graphic image viewer, should always scroll with the navigation keys.
However, in a window that has a cursor, the cursor is also moved. Sometimes it is convenient to place controls, such as a split box, next to a scroll bar.
However, too many adjacent controls make it difficult for users to scroll. If a large number of controls are needed, a standard toolbar is a better choice. Previous Table of Contents Next Splitting Windows Some applications benefit from splitting a window into two separate views that can display different information about data objects.
An example of this is the Windows Explorer, shown in Figure These individual views within a window are referred to as panes. Figure Window with a split bar Although you can split a window to view the contents of multiple data objects at the same time, it is better to use the MDI application architecture to display multiple file types simultaneously.
This gives the user a clearer idea of the individual file types. A window can be set up to be split into panes by default or as a user-configurable option. If a window allows the user to configure a window into panes, it should contain a split box in the appropriate location at the top of a vertical scroll bar or at the left of a horizontal scroll bar.
A split box is a small rectangle usually the size of the sizing border placed adjacent to the end of a scroll bar that splits or adjusts the split of a window. The user splits a window by dragging the split box to the desired position. While the user drags the split box or split bar, move a representation of the split box and split bar with the pointer, as shown in Figure When the drag is finished, display a split bar that extends from one side of the window to the other and defines the panes.
The size of the split bar should be, at minimum, the current size of the sizing border. When the user selects the Split menu item, split the window in the middle and allow the user to position the key sets the split bar at the current split bar using the arrow keys. The location.
The key aborts the split mode. Menus All applications have some sort of menu to interact with the user. Other menus depend on the application and which options the user has when working with it. There are several types of menus an application can use, including drop-down, pop-up, and cascading menus.
An application can use one or more of these. One of the most common forms of a menu is the menu bar. The menu bar, shown in Figure , is a rectangular area across the top of a window just below the title bar.
Most applications will include a menu bar on the primary window. It is not good practice to include a menu bar on any other windows within the application, because doing so can confuse the user. All applications that include a menu bar should have, at minimum, the File and Help menu titles. Figure Menu bar Even if an application includes a menu bar, it should also include pop-up menus where appropriate, as shown in Figure Pop-up menus give the user an efficient way to interact with objects on the screen because they include only those menu items related to the object under the pointer.
Figure Pop-up menu Applications should use the right mouse button exclusively for displaying pop-up menus within the application. Use the pointer location when the right mouse button is pressed at the upper-left corner of the pop-up menu. Pop-up menus can include any menu items that are appropriate for the object. However, instead of having a menu item for each object property, the menu should include a single Properties menu item, as shown on the menu in Figure When the user selects the Properties menu item, a property sheet dialog is displayed with the properties for the object.
Avoid making operations accessible only through a pop-up menu. Note that a pop-up menu does not need to be limited to items that appear in a drop-down menu. Previous Table of Contents Next Menu Interface Users can access menus with a pointer device, such as a mouse or pen, or the keyboard. Menu navigation with a pointer device is straightforward. The user selects the desired menu item by clicking the menu with the pointer device.
Windows API Reference
If the selected menu item is a menu title with a drop-down menu, the drop-down menu is displayed. As the user moves the pointer device over the menu items, they are highlighted, showing the current menu selection. If the user holds down the mouse button used to select the menu, the menu item selected when the mouse button is released is the selected menu item. If the user selects the menu by releasing the mouse button, the next time the mouse button is pressed determines which menu item is selected.
Once the menu bar is activated, the user navigates the menu with the key. The key arrow keys and selects a menu item by pressing the closes the drop-down menu if one is open; otherwise, it deactivates the menu key, or after bar.
Pressing an alphanumeric key while holding down the pressing the key, displays the drop-down menu associated with the alphanumeric key the underlined character in the menu item.
Subsequently pressing alphanumeric keys brings up the associated menu item. All menu items should have an access character defined. See Chapter 6, Menus, for more information on defining access characters. Shortcut keys or accelerators can be assigned to menu items in drop-down menus.
Commands that are repetitively accessed should have a shortcut key associated with them. When the user presses a shortcut key, the menu command is carried out immediately without the menu ever displaying. Table lists the shortcut key and access character that should be used for some common menu items.However, instead of having a menu item for each object property, the menu should include a single Properties menu item, as shown on the menu in Figure To access the contents, click the chapter and section titles.
To ease the transition, in Windows 95, for developers outside and inside Microsoft, a complex scheme of API thunks was used that could allow bit code to call into bit code for most of Win16 APIs and vice versa. Win64 is the variant of the API implemented on bit platforms of the Windows architecture as of [update] x and IA If you ask me a question that is answered on this page, you will look very silly.
A Windows window GUI application has a different interface for the main entry point provided by the programmer.
