    SetWindowText(...) in richedit controls

    I have a really annoying problem... When I set the text in a richedit or edit control, using SetWindowText("blah") the text appears selected (marked) by default, and I just cant find a way of unmarking it without clicking in the edit window. Anyone but me who have (has?) had problems with this? Im using MFC, Visual C++ .NET.

    You can control the selection in both Edit and RichEdit controls using the EM_SETSEL message.
    For MFC objects, you can use CEdit::SetSel or CRichEditCtrl::SetSel.

    Yeah, I tried that, but neither of my controls (same with both Edit and Richedit) responds to SetSel messages. Someone must have experienced this, and there must be a way to get rid of it...

    Alright, heres the part were I set the text wich results in marked text...

    pRichEditCtrl = (CRichEditCtrl*)GetDlgItem(IDC_RICHEDIT21);
    pRichEditCtrl->SetWindowText("texttexttext");
    pRichEditCtrl->SetSel(-1,0);

    I've tried other combinations with SetSel()... like 0, 5.
    I also tried adding a event handler for EM_SELCHANGE but the function doesn't get called... i've run out of ideas.

    Actually, SetWindowText() will clear the selection (as it should).

    If you can zip up and attach a very small, wizard-generated dialog app that demonstrates the issue, I'll take a look at it.

    I created a simple dialog app and both CEdit and CRichEditCtrl work as expected.

    A really small example of my problem can be found here:

    Thank you for helping me out with this! Hope you find something.

    Ok.
    Since the Edit control is the first control in the dialog and you are returning TRUE from OnInitDialog(), the system sets the keyboard focus to the Edit control. Apparently, this also means that everything in the control is selected.

    To fix the problem, set the focus explicitly and return FALSE from OnInitDialog().
    Code:
        CEdit *pEdit = (CEdit*)GetDlgItem(IDC_EDIT1);
        pEdit->SetWindowText(_T("Test"));
        pEdit->SetFocus();
        return FALSE;  // return TRUE  unless you set the focus to a control
    gg
