Splash screen with text on it that uses its own thread

Download Source Code and Example


Shows a splash screen with extra features:
  • Enables dynamic writing of text on the splash-screen
  • Enables dynamic displaying bitmaps transparently on the splash-screen
  • All text-effects (text, sizes, fonts, positions) can be changed within a timer-procedure This allows you to create "animated" splash-screens
  • Uses a second thread, useful especially for long startup-time of application

How to use:

1. You have to create the spash within your CMainFrame::OnCreate().
Then, set bitmap, text and some other settings (text-positions and how long the splash should appear) and call CreateThread().
That's all. The thread is destroyed and deleted automatically!
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
	CSplashThread *pThread = new CSplashThread();
	pThread->AddStringHeaderMain("My Application");
	// .. some other settings
	pThread->SetTimerDuration(5000); // 5 seconds

	if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
		return -1;
	// ...
2. If you want extra features, create your own thread-class derived from CSplashThread (as done in the sample, download-size is 140 kB). Within this sample, the internal timer is activated. Each timer resets the position of the Header-text and repaints the splash. This creaes an animated splash-screen.

How it works:

* The splash-screen uses the class CSplashThread which is derived from CWinThread. The splash-Window is created from the internal CSplashThread::InitInstance(). This function is called when the thread is created with CWinThread::CreateThread().
* In InitInstance() the Splash-Window is created. Then the splash-window redirects some important messages, like painting, timer, to the creating CSplashThread-class. This class handles these messages.
* The thread is destroyed when the "finish-timer arrives" with SetTimerDuration(). It calls HideSplashScreen() (you can call this function also directly, like in the sample). HideSplashScreen() calls DestroyWindow() of the splash-window.
* If you want extras, just derive from the class and override some functions, as shown in the example.


* If you have enchancements to the code, mail to mloibl@moss.de
* The sample uses the function DrawTransparentBitmap(). The original code is from Q79212 and some places also here on www.codeguru.com. It is changed, because the code doesn't work with mapping-modes other than MM_TEXT
* There should be no reason for the code not working with unicode
* This code was build with MFC shipped with VC++5.0, Enterprise Edition, Service Pack 3
