Using AVI Cap API's

Question

Hi I am using API cap API to connect my applicaiton to webcam.... can using grabframe api to capture the frame..

Sample funtion to grap the frame is function body

Grab()
{
capGrabFrame(web_cam); 

  capEditCopy(web_cam); 

  OpenClipboard(); 

  HANDLE hClipBoard = GetClipboardData(CF_DIB);

  BITMAPINFOHEADER* pBITINFO; 

  pBITINFO= (BITMAPINFOHEADER*)GlobalLock(hClipBoard); 

                unsigned char* imagedata = (unsigned char*)pInfo ;   

  GlobalUnlock(hClipBoard);  

  CloseClipboard(); 

  FILE * imagefile;

  imagefile = fopen ("C:\\Image.bmp" , "wb+");

  fwrite ((unsigned char*)imagedata, 1 , 360*240, imagefile ); 

  fclose (imagefile ); 


}

I dont know where is the problem :( ... As when i open the image.bmp ... i am unable to see anything.... Also i dont want to use the capFileSaveDIB API... Because i want the direct access to Image Captured array pixels, so that later i need to change to jpeg format using those pixel value.. can any body please help me out
