Richedit and clipboard

[ToutEnMasm]

I try (without success) to copy paste (in text format) the code of this page in a richedit:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms649016(v=vs.85).aspx#_win32_Using_the_Owner_Display_Clipboard_Format
Results are various and not verry good:
Sometimes i got the last copy of text and the passed text isn't the same in  the edit than in the richedit.
I have made an executable to test this.
The goal is to have the same write in the edit and in the richedit.

Yves,

I am getting identical content with your test piece, what differences are you getting ?

[ToutEnMasm]

I got a single line in the richedit and when i use the copy in text format in the richedit ,the text doesn't appear or is truncated.

Multiple lines in the RichEdit here but clearly the text is truncated.
It works fine with RichMasm, I get

You will get better results with this modification in line 200:

You must got:

HWND hwnd;
UINT msg;
WPARAM wParam;
LPARAM lParam;
{
    static RECT rcViewer;

    RECT rc;

    LPPAINTSTRUCT lpps;

    switch (msg)
    {
        //
        // Handle other messages.
        //
        case WM_PAINTCLIPBOARD:
            // Determine the dimensions of the label.

            SetRect(&rc, 0, 0,
                pboxLocalClip->rcText.right + CX_MARGIN,
                pboxLocalClip->rcText.top * 2 + cyText
            );

            // Center the image in the clipboard viewer window.

            if (rc.right < rcViewer.right)
            {
                rc.left = (rcViewer.right - rc.right) / 2;
                rc.right += rc.left;
            }
            if (rc.bottom < rcViewer.bottom)
            {
                rc.top = (rcViewer.bottom - rc.bottom) / 2;
                rc.bottom += rc.top;
            }

            // Paint the image, using the specified PAINTSTRUCT
            // structure, by calling the application-defined
            // PaintLabel function.

            lpps = (LPPAINTSTRUCT) GlobalLock((HGLOBAL) lParam);
            PaintLabel(lpps, pboxLocalClip, &rc);

It is only copiing pieces of codes that i have a probem

[jj2007]

You must got:

LRESULT CALLBACK MainWindowProc(hwnd, msg, wParam, lParam)
...  return 0;
}

It is only copiing pieces of codes that i have a probem

For that short piece of code, both controls show the same result. You will get trouble if you paste code that is longer than the edit control's limits, therefore in RichEdit you got the EM_EXLIMITTEXT message. I am sure you just forgot it, no problem.

By the way, the URL you posted is cute - I learnt a new function:

Code Select Expand

MsgBox 0, str$(rv(GetClipboardSequenceNumber)), "Hi", MB_OK

Extremely useful to check if the clipboard has changed :bg

Bad chance ,I write code who don't work only for me.Perhaps XP SP3 ?
