The included example provides several useful routines for capturing images. All of the routines have been written to work under both 16- and 32-bit Windows platforms and they contain full palette support. The routines in the example can: - Capture the entire contents of a form. - Capture the client area of a form. - Capture the entire screen. - Capture the active window on the screen. - Capture any portion of any window given a handle to it. - Create a Picture object from a bitmap and a palette. - Print a Picture object as large as possible on the page. Visual Basic 4.0 introduced a new Picture object. The Picture object is actually a standard OLE type and it is documented in the Control Developer's Kit (CDK.) The CDK includes the function OleCreatePictureIndirect which can be used to construct new Picture objects from Visual Basic 4.0. The routine CreateBitmapPicture in the example calls OleCreatePictureIndirect to build a Picture object from a handle to a bitmap and a handle to a palette. If the Picture includes a valid palette, Visual Basic will know to use it when rendering the Picture to the screen or printer. The CreateBitmapPicture routine is used by the CaptureWindow routine to construct Picture objects containing a bitmap of a part or all of a window. The CaptureWindow routine in the example captures any portion of a window given a window handle. The routine includes several parameters for describing the exact portion of the window to capture. Capture Window works by copying the on-screen image of a window into a new bitmap. It also checks to see if the screen has a palette and if so it makes a copy of it. CaptureWindow then calls CreateBitmapPicture to construct a bitmap from the newly created bitmap and palette. The CaptureForm, CaptureClient, CaptureScreen, and CaptureActiveWindow routines included in the example all use CaptureWindow to capture specific windows. CaptureForm and CaptureClient both call Capture window and pass it the hWnd property of a Form object. CaptureScreen simply gets the handle to the desk top window and calls CaptureWindow. Similarly, CaptureActiveWindow just gets the window handle of the active window and calls CaptureWindow. Once the desired image is captured in a Picture object, it is easy to print in Visual Basic 4.0 using the PaintPicture method of the Printer object. The example provides the routine PrintPictureToFitPage that uses the PaintPictureMethod to print the captured images as large as possible in the printable area of the page. View example now.
