usually when you use some variable or function, without including the headerfile, where it is defined,
you will get such problems.
are you facing any?
|
|
|
|
|
No, not at all. This is a linker error, meaning that the compilation went ok (so, all required header files were included). But, the linker cannot find a variable. It comes usually because you declared somewhere an extern variable (with the extern keyword) but forgot to define it in a specific cpp file.
|
|
|
|
|
Check whether you have added the cpp file in the project( take the file view and check the cpp file is under the "Source Files" ).

you mean it is working in vc6 and not in .net 2003.

When I am checking the .Wav file using mmioDescend(hSrc ,&mmckInfoParent,NULL,MMIO_FINDRIFF );, it is returning MMIOERR_OUTOFMEMORY in debug mode. But Release mode works well.
What could be the reason for this?
Thanks & Regards,

In release mode it is working surely because your code isn't automatically checked as in debug mode, but this doesn't means that there isn't an error.
You have to fiind it in debug mode!

The problem resolved after I moved some variables from inside class of header file to .cpp file as file level variable.(like MMIOINFO variables)
Thanks for your suggestion.

Hi,
On my Dialog I've got a "picture control" element. It is assigned with a var "m_pictureControl" in the code.
I draw an image inside the border of the picture control with GDI+. The problem that occurs is, that the image overpaints the border of the picture control (only when zoomed, otherwise I can shrink it, so that it can fit inside).
I get the area where the image will be drawed like that:
CClientDC dc(&m_pictureControl);
Graphics graphics(dc);
So it will have the dimension of the picture control, but unfortunately with the borders. Is there a way to somehow shrink the "graphics" object/area?
Thx, Shi

you can use the Graphics::SetClip() function to clip the border.
What I mean is, get the client rect of the picture control. Deflate it by the width of the border( 1 or 2 pixel ), then apply this rect to SetClip() function.
