Comments

The RegisterApp function registers the calling application for use of SftPrintPreview/DLL controls.

This function allows SftPrintPreview/DLL to register all required window classes for the calling application. This call has to be made before any SftPrintPreview/DLL controls can be created.

An application should call UnregisterApp once the application no longer uses SftPrintPreview/DLL controls.

The call to this function should be made during application initialization.

Example

C

int PASCAL WinMain(HINSTANCE hinst, HINSTANCE hinstPrev, LPSTR Cmd, int cmdShow)
{
    SftPrintPreview_RegisterApp(hinst); // Register application
    .... application message loop
    SftPrintPreview_UnregisterApp(hinst); // Unregister application
    return msg.wParam;
}

C++

BOOL CSampleApp::InitInstance() // based on CWinApp
{
    CSftPrintPreview::RegisterApp(); // Register to use SftPrintPreview/DLL
    .... other initialization
    return TRUE;
}
