That suggests the your resource ids are also invalid. Check that all the values match up with their target resources and are correctly loaded into your final application.

[VCProgrammer]

but when i set Button style BS_ICON ,than its also working on XP.it means ids are not invalid,i think so... i really cant get it whats going wrong here, is there any other method to display icon on button with text.

Without a lot more information I don't think we can either.

You need to show some more of the failing code and the error messages or codes that you receive. Remember, we cannot see your system and are not familiar with your program.

I suspect the error 87 should be ignored as you have not checked if the previous function was successful or not. You can validate that by calling SetLastError(0) before the SetIcon() call. You also say that when you set icon style to FALSE it does not display the icon; isn't that what it should do?

[VCProgrammer]

i set icon style to FALSE,coz i dont want only icon on button is display i want icon and text both are display on button....

[Lost User]

See the remarks section[^].

[VCProgrammer]

thanks for your guidance and support ,but please help me what function use to display text and icon on button....

[Lost User]

Use the methods and properties as described in the documentation[^].

[VCProgrammer]

according to the documentationt set icon on button use CButton:SetIcon method,that have i already used...as you know also is not working fine...

[Lost User]

I just tested this on my system and it works fine, using the BM_SETIMAGE message. I am not sure how you would do that in MFC but I guess in much the same way.

[VCProgrammer]

sir you tested this on XP?

[Lost User]

No, Windows 7.

[VCProgrammer]

sir i already told so many times os version upper than XP, my code also working fine, the problem is just about XP and lower version...

Do you have Visual Styles enabled[^]?
