Change char inserted using Alt+Unicode in CRichEdit

由 心已入冬 提交于 2020-02-06 03:30:31
问题 I want to change a unicode char inserted using Alt+Unicode code from the keyboard. I used PretranslateMessage for changing the chars inserted directly from the keyboard and it worked. But with the Alt+Unicode code method it does not. Here is the code: Microsoft Word has this functionality when enabling show/hide paragraph marks. BOOL CEmphasizeEdit::PreTranslateMessage(MSG* msg) { if (msg->hwnd == m_hWnd) { if (msg->message == WM_CHAR) { if (TheApp.Options.m_bShowWSpaceChars) { if (msg-

问题 I tried using CRichEditCtrl::GetLine() to retrieve the text of a given line of a rich-edit control in an MFC application built with VS2015 in Unicode mode, and running on Windows 10. I wrote this helper function: CString GetLine(CRichEditCtrl& richEdit, const int lineNum) { int lineLength = richEdit.LineLength(richEdit.LineIndex(lineNum)); if (lineLength == 0) { // Empty line return CString(); } const int kMinBufferLength = sizeof(int) / sizeof(wchar_t); const int bufferLength = max

How to display Red Squiggly Lines in CRichEditCtrl in MFC

问题 I am working on implementing spellchecker in an MFC application. What I want to do is display red lines under incorrectly spelled words. I found one example where it is done but it works only for a simple edit box because it can simply use the edit controls default font for doing calculations to draw the squiggly lines. But it does not work for a rich edit control as in rich edit control it is possible that different words can have different fonts. In this case the example I found draws lines

CRichEditCtrl appending colored text?

问题 I have a CRichEditCtrl in an MFC project, which I use as a report log. Depending on the given situation, I need to append different colored text to the control (ie. a blue line for standard notifications, a red line for errors, etc). I've come pretty close to getting this to work, but it still behaves strangely: void CMyDlg::InsertText(CString text, COLORREF color, bool bold, bool italic) { CHARFORMAT cf = {0}; CString txt; int txtLen = m_txtLog.GetTextLength(); m_txtLog.GetTextRange(0,
