just add if ( m_wndToolBar.OnCmdMsg(...) ) { return TRUE; } in function CMainFrame::OnCmdMsg(...) before return default process.

I already try some cases, it works well in doc/view case. I get some source codes from sourceforge.net, it uses ON_COMMAND_EX and is not doc/view case. it just has CMainFrame and a view derived from CWnd, without doc.

I need process the message in the child window and parent window. child window uses ON_COMMAND_EX and parent window uses ON_COMMAND.

Thank you for your reply. I already google it and search it on codeproject and codeguru before posting this message. Yes, it works well for Doc & View architecture. my architecture is CMainFrame and CMyView (derived form CWnd, not CView) and without Doc. And it has a custom tool bar and a custom status bar.

it seems that ON_COMMAND_EX just works in doc/view architecture. Can anyone give me some tips about it? thank you.

thank you very much, this one is work. http://www.codeproject.com/clipboard/clipnutshell.asp

Thank you. yes, i already try this function and COleDataSource::SetClipboard(). but they are not work. and below is my code. if ( OpenClipboard() ) { EmptyClipboard(); SetClipboardData(CF_BITMAP, m_hDrawingSurface); CloseClipboard(); } code using ole COleDataSource* pDataSource = new COleDataSource; TRY { // Create a shared file and associate a CArchive with it CSharedFile file; CArchive ar(&file,CArchive::store); BITMAPFILEHEADER bmfh; int nBitsOffset = sizeof(BITMAPFILEHEADER) + m_bmpInfoHeader.biSize; LONG lImageSize = m_bmpInfoHeader.biSizeImage; LONG lFileSize = nBitsOffset + lImageSize; bmfh.bfType = 'B'+('M'<<8); bmfh.bfOffBits = nBitsOffset; bmfh.bfSize = lFileSize; bmfh.bfReserved1 = bmfh.bfReserved2 = 0; //Write the bitmap file header ar.Write(&bmfh, sizeof(BITMAPFILEHEADER)); //And then the bitmap info header ar.Write(&m_bmpInfoHeader, sizeof(BITMAPINFOHEADER)); ar.Write(m_pDrawingSurfaceBits, lImageSize); ar.Close(); // specify HGLOBAL handle to text data pDataSource->CacheGlobalData(CF_DIB, file.Detach()); pDataSource->SetClipboard(); } CATCH_ALL(e) { delete pDataSource; THROW_LAST(); } END_CATCH_ALL

at first, please visit this topic. http://www.codeproject.com/bitmap/drawing2bitmap.asp and my question is below. how to copy the bitmap data to clipboard? Thank you in advance.

thank you! i know that, but i have to get the big one.

thank you, i will give it a try.

i want to capture a window to a bitmap. when the document size is bigger than current viewable rectangle, if using the document size to the captured image will has a big black block. CSize size = GetTotalSize(); CClientDC dc(this); CDC memDc; if(!memDc.CreateCompatibleDC(&dc)) { return ; } CBitmap bitmap; if( !bitmap.CreateCompatibleBitmap(&dc, size.cx, size.cy) ) { return ; } CBitmap* pOldBitmap = memDc.SelectObject(&bitmap); memDc.BitBlt(0, 0, size.cx, size.cy, &dc, 0, 0, SRCCOPY ); if( OpenClipboard() ) { EmptyClipboard(); SetClipboardData(CF_BITMAP, bitmap.GetSafeHandle()); CloseClipboard(); } memDc.SelectObject(pOldBitmap); any suggestion or tips will be great help. thank you in advance.

Thank your reply. I miss define a macro, so the dll cannot be export
