It seems CClientDC is the key. This does not work:

hdc = ::GetDC(m_hWnd); // Tried NULL too...

// Create compatible dc

What's the difference between GetDC and CClientDC?

You're using the code I shared with you?

Not sure what's going on there. I'm using that exact code in a production release without any problems.

When pasting the image into Paint, it tells me:

---------------------------
Paint
---------------------------
The information on the Clipboard can't be inserted into Paint.
---------------------------
OK
---------------------------

What?!

Hi,

Here's the code I'm currently using for this purpose.

void CDFDChartControl::CopyToClipboard()
{
    BITMAP bmpInfo;
   m_bmpCache.GetBitmap(&bmpInfo);

   CBitmap bitmap;
   CClientDC dcClient(AfxGetMainWnd());

   CDC dcDest;
   dcDest.CreateCompatibleDC(&dcClient);

   CDC dcSource;
   dcSource.CreateCompatibleDC(&dcClient);

    HBITMAP oldhBitmap = (HBITMAP)dcSource.SelectObject((HBITMAP)m_bmpCache);

    bitmap.CreateCompatibleBitmap(&dcClient, bmpInfo.bmWidth, bmpInfo.bmHeight);

    CBitmap* pOldBitmap = dcDest.SelectObject(&bitmap);

    ::BitBlt(dcDest, 0, 0, bmpInfo.bmWidth, bmpInfo.bmHeight, dcSource, 0, 0, SRCCOPY);

    dcSource.SelectObject(oldhBitmap);
   dcDest.SelectObject(pOldBitmap);

    VERIFY(::OpenClipboard(AfxGetMainWnd()->m_hWnd));
    VERIFY(::EmptyClipboard());
    VERIFY(::SetClipboardData(CF_BITMAP, bitmap.Detach()));
    ::CloseClipboard();
}]]> Mon, 18 Apr 2011 09:56:08 +0000 http://forum.codejock.com/forum_posts.asp?TID=18181&PID=63951&title=resolved-copy-to-clipboard#63951 <![CDATA[(RESOLVED) Copy to clipboard : I keep getting a black image....]]> http://forum.codejock.com/forum_posts.asp?TID=18181&PID=63929&title=resolved-copy-to-clipboard#63929 Author: znakeeye

I keep getting a black image. What am I doing wrong?

This is my copy-function:

BOOL CopyBitmap(CBitmap &bmpDest, CBitmap &bmpSource)
{
bmpDest.DeleteObject();

BITMAP bm;
bmpSource.GetBitmap(&bm);

CDC sourceDC;
sourceDC.CreateCompatibleDC(NULL);

bmpDest.CreateCompatibleBitmap(&sourceDC, bm.bmWidth, bm.bmHeight);

CDC destDC;
destDC.CreateCompatibleDC(NULL);

CBitmap *pOldSourceBitmap = sourceDC.SelectObject(&bmpSource);
CBitmap *pOldDestBitmap = destDC.SelectObject(&bmpDest);

destDC.BitBlt(0, 0, bm.bmWidth, bm.bmHeight, &sourceDC, 0, 0, SRCCOPY);

sourceDC.SelectObject(pOldSourceBitmap);
destDC.SelectObject(pOldDestBitmap);

return (bmpDest.m_hObject != NULL);
}

You better create copy of bitmap because you should "detach" it to clipboard:

VERIFY(SetClipboardData(CF_BITMAP, bmpCopy.Detach()));

Hello,

I need to copy a chart image (rendered via CXTPChartControl) to the Windows clipboard.

I tried deriving from CXTPChartControl and adding a method that copies the contents of the CBitmap cache object (m_bmpCache member) to the clipboard, but it does not work. Here's what I'm trying to do (stripped of error checking for brevity):

VERIFY(OpenClipboard());
VERIFY(EmptyClipboard());
VERIFY(SetClipboardData(CF_BITMAP, m_bmpCache.GetSafeHandle()));
CloseClipboard();

None of these function calls fail, but clipboard contents are not valid. Perhaps CBitmap cache object is not safe to use for this purpose?
