Do you want to make a desktop elf that is transparent on the desktop, dynamically singing? Below I use an example of my original to teach you how to implement it. The example running interface is as follows:
Basic ideas: Use the transparent bitmap method to display the bitmap on the desktop, replace the bitmap at the timing to achieve the animation effect, and then play the internal WAV resource file method to play with the WAV file or (right click).
The specific implementation steps are as follows:
1. Import a WAV file in the new project file (VC6.0), name "West", and import two bitmap name "West1" and "West2".
2, create a new .h file, name TransparentWnd.h
The code content is as follows:
#if! defined (AFX_TRANSPARENTWND_H__6508F000_5685_11D3_9001_CBBD225E6BC4__INCLUDED_)
#define AFX_TRANSPARENTWND_H__6508F000_5685_11D3_9001_CBBD225E6BC4__INCLUDED_
#iF _MSC_VER> 1000
#pragma overce

3, create a new .CPP file, name: TransparentWnd.cpp
The code content is as follows:

4. The initialization instances of the initialization instances in the application class (west.cpp) code can be changed below:
Bool cwest :: initInstance ()
{
SRAND (Time (null);
// Only run a program instance, if you have run, exit
IF (FindWindow (Null, "Westward Journey Classic Series - Emotional World")) EXIT (0);
TransparentWnd * pframe = new transparentw
m_pmainwnd = pframe;
// Create and Load The Frame with its resources
CRECT RECT (0, 0, 100, 100);
Pframe-> CreateTransparent ("Westward Journey classic series - emotional world", Rect); // idb_mask, idb_back;
Pframe-> centerWindow (); // Initial display Form Location
Pframe-> showwindow (sw_show); return true;
}
