I cannot make Activex controls transparent in Measurement Studio for Visual C

[billfu]

Following your instructions,I cannot make Activex controls transparent in Measurement Studio for Visual C++ yet.My problem is that when I set the application's background as a BMP photo,the Activex controls can not be maken transparent.I attach the VC++ file to you.Would you please help me figure
it out?Thanks!




Former Message:
Now I am using the Measurement Studio for Visual C++ evaluation version.

In my program,I often need to change the skin of the interface.The skins maybe are some photos,and BMP files,So I need the Measurement Studio activeX
controls which bear transpanrent background.Could you please tell me how to do it?I can change the control's backcolor but I
cannot make it transparent.Maybe the
controls in Measurement Studio don't have this feature.If no this feature,you should improve it.I have ever used the activeX FXTools Gold 5.0,which
produced by GrapeCity inc.All the activex controls' background can be maken transparent.I think it's very important.

You can do this by making the control windowless (set the Windowless property to true). Note that the ActiveX container in MFC 4.2 (which ships with Visual C++ 6.0) does not support windowless controls, but the ActiveX container in MFC 7.0 (which ships with Visual C++ .NET) does support windowless controls. If you're using Measurement Studio for Visual C++ and do not have the free update for Visual C++ .NET, see the National Instruments and Visual Studio .NET page for more information. Also, Visual Basic's ActiveX container also supports windowless controls.
