what about this :-

while(PeekMessage(&msg,0,0,0))
{
 DispatchMessage(&msg);
}

when u click on any variable name, we'd find "go to declaration","go to reference".. but if u click on it, its not taking the cursor to the decl or ref, its simply saying "The Symbol 'VAL1' is not defined".. but i've declared everything inside the class n i get no errors.

and code assistance is not coming too... when you type the .(dot) after an object or something, nothing is displayed. should we change any setting in the IDE? Frown | :(

thanks in advance

Did you declare the variable in a header or a code file ?
The class browser only looks in header files, certainly on VC6.0.

Close down your workspace, Delete the project.ncw file and restart your computer. Next time when you open your project the Intellisense will be working

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!
