Key Methods in PDF Viewer OCX Control (ActiveX):
Here’s a detailed description of each method in the PDF Viewer OCX Control (ActiveX), showcasing the core functionality and how each method contributes to PDF viewing and manipulation:
1. BOOL OpenPDF(LPCTSTR lpszPDFFile, ...)
Description:
This method is used to open a PDF document within the viewer. By passing the file path of the PDF (lpszPDFFile), the method initializes the viewer and loads the specified document. This allows developers to easily display any PDF file from their application. Parameters:
lpszPDFFile: A string containing the path to the PDF file that needs to be opened. Usage:
OpenPDF("C:\\path\\to\\file.pdf");
2. ClosePDF()
Description:
This method closes the currently opened PDF document and the viewer window. It is useful for cleaning up resources or when switching to another document. This function ensures that the PDF viewer is properly shut down. Usage:
ClosePDF();
3. void SetFindText(LPCTSTR lpszFindText)
Description:
Sets the text string (lpszFindText) that you want to search for within the PDF. After calling this method, you can use the FindNextText() and FindPreviousText() methods to locate the occurrences of the text in the document. Parameters:
lpszFindText: A string representing the text to be searched in the PDF. Usage:
SetFindText("search text");
4. void FindNextText()
Description:
Finds the next occurrence of the text previously set by the SetFindText() method. This method will automatically scroll to the found text if it's within the viewable area of the document. Usage:
FindNextText();
5. void FindPreviousText()
Description:
Finds the previous occurrence of the text previously set by the SetFindText() method. It works similarly to FindNextText(), but navigates backward through the document. Usage:
FindPreviousText();
6. void RotateViewLeft()
Description:
Rotates the current PDF page 90 degrees counterclockwise. This function allows users to adjust the page orientation to better view the content, especially for landscape-oriented documents. Usage:
RotateViewLeft();
7. void RotateViewRight()
Description:
Rotates the current PDF page 90 degrees clockwise. Similar to RotateViewLeft(), this method enables the rotation of the page to fit the viewer's needs. Usage:
RotateViewRight();
8. void ViewNextPage()
Description:
Moves to the next page in the PDF document. This is useful when users want to navigate forward through the document, either with a button or automated process. Usage:
ViewNextPage();
9. void ViewPreviousPage()
Description:
Moves to the previous page in the PDF document. This method is used to allow users to navigate backward through the document. Usage:
ViewPreviousPage();
10. void ViewFirstPage()
Description:
Jumps directly to the first page of the PDF document. This method is helpful for applications that want to quickly reset the viewer to the start of the document. Usage:
ViewFirstPage();
11. void ViewLastPage()
Description:
Jumps directly to the last page of the PDF document. It’s ideal for applications where users need to quickly view the end of the document. Usage:
ViewLastPage();
12. void ShowHideBookmarks()
Description:
This method toggles the visibility of the bookmark window in the viewer. When called, it either shows or hides the bookmarks pane, allowing users to navigate to different sections within the document more efficiently. Usage:
ShowHideBookmarks();
13. void ViewPage()
Description:
Allows you to navigate to a specific page within the PDF document. This method gives developers control over which page is displayed, facilitating direct access to any page in the document. Usage:
ViewPage(3); (to go to page 3)
14. void ZoomFitPage()
Description:
Automatically adjusts the zoom level to fit the entire page within the visible area of the viewer window. This method is useful for ensuring that users can view the entire page without horizontal or vertical scrolling. Usage:
ZoomFitPage();
15. void ZoomActualPage()
Description:
Zooms the page to its actual size (100% zoom). This ensures that the document is displayed at the original resolution, so users can view it in its true proportions without any scaling. Usage:
ZoomActualPage();
16. void ZoomFitWidth()
Description:
Adjusts the zoom to fit the width of the page within the viewer window. This is ideal when the document's content is wider than the screen but doesn't require scaling the entire page to fit. Usage:
ZoomFitWidth();
17. void Zoom(float nZoom)
Description:
Zooms the document by a specific percentage (nZoom). For example, calling Zoom(150) will zoom the document to 150% of its original size. This method allows developers to implement custom zoom levels. Parameters:
nZoom: The zoom factor, represented as a float (e.g., 1.0 for 100%, 1.5 for 150%). Usage:
Zoom(1.5);
18. void ZoomIn()
Description:
Zooms in on the document by a predefined amount, increasing the size of the content for closer inspection. This method is typically used when the user wants to see more detail. Usage:
ZoomIn();
19. void ZoomOut()
Description:
Zooms out on the document, decreasing the size of the content so users can view more of the document at once. It’s useful for navigating through large documents quickly. Usage:
ZoomOut();
20. void ViewModeSinglePage()
Description:
Switches the viewer to single-page mode, where only one page is visible at a time. This is ideal for users who prefer to view one page at a time for better focus and clarity. Usage:
ViewModeSinglePage();
21. void ViewModeFacing()
Description:
Sets the viewer to "facing" mode, where two pages are displayed side by side. This is typically used for viewing documents in a book-like layout. Usage:
ViewModeFacing();
22. void ViewModeContinuous()
Description:
Enables continuous scrolling mode, where pages are displayed one after another in a continuous flow. This mode is ideal for users who want to quickly skim through long documents. Usage:
ViewModeContinuous();
23. void ViewModeContinuousFacing()
Description:
This mode combines continuous scrolling and facing pages, allowing users to view pages side by side in a continuous flow. This is ideal for viewing documents that require quick navigation while retaining the dual-page layout. Usage:
ViewModeContinuousFacing();
24. void SetViewMode(long nViewMode)
Description:
Sets the page layout view mode by passing a specific mode as a parameter. Developers can use this method to dynamically switch between different viewing modes (single page, facing, continuous, etc.). Parameters:
nViewMode: An integer representing the view mode. (e.g., 0 for single page, 1 for facing pages, etc.) Usage:
SetViewMode(0); (to set single-page mode)
25. void SetRegCode(LPCTSTR lpszRegCode)
Description:
This method is used to set the license key for the PDF Viewer OCX control. By passing a valid registration code (lpszRegCode), you can activate the control and enable its full functionality. Parameters:
lpszRegCode: A string containing the registration code. Usage:
SetRegCode("your-license-key");
