I need to paint bitmaps to a page in a Tab Control that is also in
another thread. And I am not sure how to write the "CClientDC" statement.
What I have tried is causing errors that would seem to be caused by the
"CClientDC" statement requiring a pointer. Also, these statements will be

a loop with a certain number of bitmaps being painted on the page, and the
position for the next bitmap moved for each loop. So, the "CClientDC"
statement may have to be outside of the loop.

These are the errors I am getting:

error C2065: 'bmp' : undeclared identifier
error C2228: left of '.LoadBitmapA' must have class/struct/union type
error C2065: 'cdc' : undeclared identifier
error C2228: left of '.CreateCompatibleDC' must have class/struct/union

type

error C2228: left of '.SelectObject' must have class/struct/union type
error C2065: 'ITMAP' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'BmpInfo'
error C2065: 'BmpInfo' : undeclared identifier
error C2228: left of '.GetObjectA' must have class/struct/union type
error C2228: left of '.bmWidth' must have class/struct/union type
error C2228: left of '.bmHeight' must have class/struct/union type

error C2228: left of '.DeleteDC' must have class/struct/union type
error C2228: left of '.DeleteObject' must have class/struct/union type

And this is the code section:
{
   CClientDC dc(this); ****How is this written****
   bmp.LoadBitmap(Crd);

   cdc.CreateCompatibleDC(&dc);
   CBitmap *pOld = cdc.SelectObject(&bmp);

   ITMAP BmpInfo;
   bmp.GetObject(sizeof(BmpInfo), &BmpInfo);
   dc.BitBlt(Xpos, Ypos, BmpInfo.bmWidth, BmpInfo.bmHeight, &cdc, 0, 0,
SRCCOPY);

   cdc.SelectObject(pOld);
   cdc.DeleteDC();
   bmp.DeleteObject();
}
