Go4Expert - How adjust image to a picture box ?

Hello,

I am trying to display an image into a PDA but I have no experience programming for PDA's neither working with images. I followed more or less the instructions given in a post from this forum: "Display Bitmap in a Picture Box using MFC from a file". I am working in Microsoft eMbedded C++ 4.0. First, I created a dialog based MFC project and added a Picture Control. Then I added the variable CStatic and load the bitmap. The problem is that it does not fit into the Picture Control place, I mean, the whole image is not displayed. I know that I need the StretchBlt function for adjusting it but I am doing anything wrong and it does not work. I would be very grateful if somebody could help me with this because I have been trying to solve this for a long time and I am desperate. This is the code that I have in OnInitDialog:

Code:

 

HBITMAP hBmp; 

 if((hBmp = SHLoadImageFile(_T("\\1_eli.jpg")))!=0x00000000)

 {  

  // Get the dimensions of the bitmap

  CBitmap bmp;

  bmp.Attach(hBmp);

  BITMAP bm;

  bmp.GetBitmap(&bm);  

  bmp.Detach(); 

 

  // dimensions of the control

  RECT rectScaled;

  m_imagen.GetWindowRect(&rectScaled);

  int rectW=rectScaled.right-rectScaled.left;

  int rectH=rectScaled.bottom-rectScaled.top;

 

  HDC hdc=::GetDC(m_imagen.m_hWnd);

  HDC memdc=CreateCompatibleDC(hdc);

 HBITMAP hBmp2=(HBITMAP)SelectObject(memdc,hBmp);

  //HBITMAP hBmp2=CreateCompatibleBitmap(memdc,rectW,rectH);

  //BitBlt(memdc,0,0,150,100,hdc,0,0,SRCCOPY);

  StretchBlt(hdc,0,0,bm.bmWidth,bm.bmHeight,memdc,0,0,rectW,rectH,SRCCOPY);

  //SelectObject(memdc,hBmp2);

 

  m_imagen.SetBitmap(hBmp2);   

    

 }

Thanks for your time.
