Assistance required on Bitmaps

Barm

I have an application that allows the user to bookmark different locations in a video. It saves the video images at the bookmarks. There is a listbox that shows all the bookmarks. Double-click on the listbox will bring the video to the selected bookmark position. But I'm unable to bring out the save image and display onto a picture control. I tried using CBitmap and CStatic but still unable to get the images out. I have already recode this portion dozens of times. main problem: Getting the picture to be display. (I'm able to get the full path to the selected picture) Can someone offer me advice on how to solve this? Thanks

What format are the saved images in? If they are BMP,JPEG,GIF you can use the OLE picture support to render them, and you could derive from CStatic to make your own picture box, or use something like the one from MSDN done by Paul DiLascia (spelling?) Steve S Developer for hire!

The images are .bmp, I have a picture control, CStatic m_StillPic I've tried using m_StillPic.SetBitmap() but without success. Can you explain the parameter inside SetBitmap(), where do I put the path to the file? Thanks

Hi, If m_stillPic is a StaticCtrl & your BMP path is "C:\\Pic.bmp" : HBITMAP hBitmap = (HBITMAP) ::LoadImage(AfxGetInstanceHandle(), _T("C:\\Pic.bmp"), IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_CREATEDIBSECTION); if (hBitmap) m_stillPic.SetBitmap(hBitmap); m_stillPic.UpdateWindow();

Hi, create a CStatic control and choose type 'rectangle'. Use the following code to draw into that window.

void DrawBitmap(CBitmap* pBitmap, CWnd* pWindow, CPoint Offset)
{
// get bitmap information
BITMAP bmpInfo;
pBitmap->GetObject(sizeof(bmpInfo), &bmpInfo);

// get source size
CSize srcSize;
srcSize.cx = bmpInfo.bmWidth;
srcSize.cy = bmpInfo.bmHeight;

// get window's client device context
CClientDC\* pDC = new CClientDC(pWindow);

// create compatible divice context for stretching
CDC\* memDC = new CDC; memDC->CreateCompatibleDC(pDC);

// load bitmap in original size
CBitmap\* old = memDC->SelectObject(pBitmap);

// copy bitmap data
pDC->BitBlt(Offset.x, Offset.y, srcSize.cx, srcSize.cy, memDC, 0, 0, SRCCOPY);

// reselect first bitmap
memDC->SelectObject(old);

// delete device context and reset pointer
delete memDC; memDC = 0;

// delete device context and reset pointer
delete pDC; pDC = 0;

}
