First let me thank you for answering my question about tabs. Processing of WM_GETDLGCODE really helped. Thank you!
Well, one more thing I want to do is to control the data that a user pastes to the control (Rich Edit): I want only text to be pasted in the control (even if in clipboard there is other data with text - just like Notepad does it). I know that there is PasteSpecial function that can be called with CF_TEXT parameter. But where to call to control all the pasteing text?

This method actually does the pasting from withing your code. It has no control over what the user might try to paste into it. If you are only interested in text, why not just use a regular edit control?

Because I need to make text colorizing. But it must be text, not tables or images or something else. I know for sure that there is a way to control the "cut-copy-paste" process... But how? MSDN says that PasteSpecial will help, but where to call it? I tried to catch WM_PASTE but my class, derived from CRichEditCtrl, can't catch it. Why???

In your derived class, add the following:
void CMyRichEditCtrl::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)
{
bool bPasted = false;
if (toupper(nChar) == 'V' && GetAsyncKeyState(VK_CONTROL))
{
if (IsClipboardFormatAvailable(CF_TEXT))
{
if (OpenClipboard() != FALSE)
{
HANDLE h = GetClipboardData(CF_TEXT);
if (h != NULL)
{
LPTSTR lptstr = (LPTSTR) GlobalLock(h);
if (lptstr != NULL)
{
SetWindowText(lptstr);
GlobalUnlock(lptstr);
bPasted = true;
}
}
CloseClipboard();
}
}
}
if (! bPasted)
CRichEditCtrl::OnKeyDown(nChar, nRepCnt, nFlags);
}

Very well done! Thank you! There is only one thing that should be added to
if (toupper(nChar) == 'V' && GetAsyncKeyState(VK_CONTROL))
- its checking for SHIFT-INS combination.
Thank you very much!

Correct. Not once have I ever used that combination to insert text.

One more and final: in your case the new text replaces the whole text in the control. So it's better to use ReplaceSel function instead of SetWindowText. Now everything is correct. Here is the final code:
<br />
void CRichEditCtrlEx::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)<br />
{<br />
bool bPasted = false;<br />
if((toupper(nChar) == 'V' && GetAsyncKeyState(VK_CONTROL)) || (nChar == VK_INSERT && GetAsyncKeyState(VK_SHIFT)))<br />
if(IsClipboardFormatAvailable(CF_TEXT))<br />
if(OpenClipboard() != FALSE){<br />
HANDLE h = GetClipboardData(CF_TEXT);<br />
if(h != NULL){<br />
LPTSTR lptstr = (LPTSTR)GlobalLock(h);<br />
if(lptstr != NULL){<br />
ReplaceSel(lptstr);<br />
GlobalUnlock(lptstr);<br />
bPasted = true;<br />
}<br />
}<br />
CloseClipboard();<br />
}<br />
if(!bPasted)<br />
CRichEditCtrl::OnKeyDown(nChar, nRepCnt, nFlags);<br />
}<br />
Thank you once more!

Hi,
I have a view class derived from CFormView. I have a timer in it which is fired for every 20 seconds. In the timer, I am repainting the form view with some bitmaps in OnPaint handler. When I am in the timer, the form view UI is stuck, i.e I am not able to click any other bottons on the form view. Can any one please give me some suggestions so that my UI responds to events even when the timer code is trying to refresh the view.
Thanks

Put the timer and the code that belongs to it in a separate thread.
That should do the trick.

Which Visual Studio ? Different versions have come with different solutions. I use Advanced Installer[^], it's a great solution, and the free version will probably do all you need ( although I bought it ).

what's wrong with Install Shield?

I've done installs with install shield. It's probably more powerful than AdvancedInstaller, but as a result, it takes a lot longer to get the same end result.

How can I add a dialog to Cview?
|
|
|
|
|
Create a new dialog class and make it a member variable for modeless, or create it in the scope of the function that calls it for modal dialogs.

By that I mean embedded a modal dialog inside a SDI view.
|
|
|
|
|
Embedding in what way ? So the modal dialog is part of the CView window ? Or just so that the modal dialog is shown by the view ? If the former, you can't. If the latter, exactly as I said. In your view, create the dialog class, and call DoModal on it.

This is an assignment and we're recommanded not to use CFormView, but somehow to mimic the CFromView ways

Oh. You said a 'Modal dialog'. Otherwise, I'd have said to use CFormView. CFormView gives you a dialog like view, it does NOT 'add a modal dialog to your CView'.
If you're not allowed to use CFormView, then create your own controls, and embed them into your CView in your view constructor.
