  1. POHow does a CRichEditCtrl know a paste operation has been performed?
    text
    copied!<p>It has methods like <code>CRichEditCtrl::Copy()</code>, <code>CRichEditCtrl::Paste()</code> which you can call, but I can't spot any messages the control is sent by Windows telling it to <em>perform</em> a paste operation. Does anyone know if such a thing exists? Or does <code>CRichEditCtrl</code> do something lower-level like monitoring WM_CHAR events? If so can I reuse any internal methods or would I just have to roll my own in order to override the standard paste functionality?</p> <p>What I actually want is for my custom subclass (<code>CMyRichEditCtrl : CRichEditCtrl</code>) to ignore any formatting on text pasted <em>in</em> to the control. Either by getting the clipboard data in a different clipboard format, or by pasting it in as normal and immediately removing formatting on inserted text.</p> <p><strong>What I tried so far:</strong></p> <ol> <li>Checking the message for WM_PASTE in <code>CMyRichEditCtrl::PreTranslateMessage()</code></li> <li>Creating a method <code>virtual void CMyRichEditCtrl::Paste()</code></li> <li>Putting a breakpoint on <code>CRichEditCtrl::Paste()</code> in afxcmn.inl</li> <li><strong>Dumping <em>every</em> message passing through <code>CMyRichEditCtrl::PreTranslateMessage()</code></strong></li> </ol> <p><strong>Results:</strong></p> <p>1: No WM_PASTE message seen<br> 2: It's never called<br> 3: It's never hit... <strong>how?</strong><br> 4: <strong>The control <em>never</em> receives any WM_COMMAND, WM_PASTE or focus-related messages. Basically only mouse-move and key-press messages</strong>.</p> <p>It seems other people have actually done this successfully. I'm wondering if my MFC version or something could be screwing it up, at this point.</p>
