Hi everyone, I have a probelm on doing the slider bar. I have looked at the tutorials on the web and they are all in MFC, however, My program is build under WIN32 API, and I would like to know the codes for controlling the slider bar. The effect i want to achieve is I have a slider bar and a Picture box for showing images, then as the slider bar moves down, the picture in the Picture box will change to the next picture. for example, if the slider bar have 10 interval, so there will be 10 pictures to be change as the slider bar moves across. |------------------------| |`````````````````````| |``|----------------|```| |``|````Picture````|```| |``|----------------|```| |`````````````````````| |``-[]---------------```| |`````````````````````| -------------------------- thanks very much, i would be apprceiated if anyone could help.

The MSDN has the complete documentation for trackbar controls.
