CBitmap - creation problem

Hi!

I am loading a file into a CBitmap object, draw it and so on. Then I save it to my own file format and like to read it afterwards again. The saved values and loaded values are the same but I cannot create a bitmap from the loaded values.
Here is my code:

//read from my file bitmap header
fread(&bit,sizeof(BITMAP),1,f);
int bsize=bit.bmWidthBytes*bit.bmHeight;

//read bitmap bits
buf=(BYTE*)malloc(bsize);
fread(buf,bsize,1,f);

//delete previous bitmap
DeleteObject();
//and create new one
CreateBitmap(bit.bmWidth,bit.bmHeight,bit.bmPlanes,bit.bmBitsPixel,buf);

The result of CreateBitmap() is 1 so it seems to work. But my screen stays blank. When I remove DeleteObject and CreateBitmap and use SetBitmapBits with my loaded bitmap data then I can see my saved picture. This is because I overwrite the previous loaded picture.

The problem seems to be CreateBitmap...anybody an idea?

Please help!!
Thx
Flo

Sure, but I checked the written and read data and its the same so I think this works. But here it comes:

BITMAP bit;
BYTE *buf;

//get loaded bitmap header
GetObject(sizeof(BITMAP),&bit);
int bsize=bit.bmWidthBytes*bit.bmHeight;

//get bitmap bits
buf=(BYTE*)malloc(bsize);
this->GetBitmapBits(bsize,buf);

//write
fwrite(&bit,sizeof(BITMAP),1,f);
fwrite(buf,bsize,1,f);

Hope it gives you an idea!
Thx!

Hi

I am using the MprConfigGetFriendlyName function in a program of mine.
It works well if I'm an administrtor on my machine, but when I switch
to a restricted user, I get "Access denied" from the funciton.

I can't find any info about rights anywhere on MSDN.
Can anyone give me a hint of how to proceed.

Create your controls with WS_TABSTOP, and set the tab order for movement.

Trap the 'TAB' key in the parent window and move over the controls using GetNextDlgTabItem function. Hope this helps.

U mean see the DLL ?
If so DLL Spy will see the DLL actions.
Try see attach and detach to load and unlad DLL or drivers

Is this some sort of pop quiz, or do you just want information about message routing ?
