Please go through the code and point out the mistake in the code.

 void CPictureBox::ShowBitmap(CPaintDC *pdc) 
{
     //Create a device context to load the bitmap into
     CDC dcMem;
     dcMem.CreateCompatibleDC(pdc);

     //Get the Display area available
     CRect lRect;

I felt that it must be all right if i use bm instead of bmpBitmap

m_bmpBitmap->GetBitmap(&bm);
