Re: How do I use IPictureDisp in ATL?

[Rob]

Try sticking the following code in the OnDraw handler:

// Draw the background image

IPicture *pPic;

HBRUSH hBrush;

HPEN hPen, hPenOld;

HBITMAP hBmp, hBmpOld;

HDC hDC;

BOOL bBitBlt;

m_pPicture->QueryInterface(IID_IPicture, (void**)&pPic);

// Get the OLE picture object's handle

if(pPic){

pPic->get_Handle((OLE_HANDLE*)&hBmp);

pPic->Release();

pPic = NULL;

}

// Create a memory DC

hDC = CreateCompatibleDC(di.hdcDraw);

// Select the bitmap into the memory DC

hBmpOld = (HBITMAP)SelectObject(hDC, hBmp);

// Blt the bitmap from the memory dc to the screen

bBitBlt = BitBlt(di.hdcDraw,

di.prcBounds->left,

di.prcBounds->top,

di.prcBounds->right - di.prcBounds->left,

di.prcBounds->bottom - di.prcBounds->top,

hDC,

0,

0,

SRCCOPY);

// Select the old bitmap back into the memory DC

hBmp = (HBITMAP)SelectObject(hDC, hBmpOld);


// Delete the memory DC

DeleteDC(hDC);
