Did you try handling GetFocus instead of SetFocus?

[valikac]

Use EN_SETSEL ----- // editHWnd is the handle to your edit control // from and to are the beginning and end of your select range SendMessage(editHWnd, EM_SETSEL, static_cast(from), static_cast(to)); ----- Kuphryn

I meant EM_SETSEL. Kuphryn

There's no EN_SETSEL. Tomasz Sowinski -- http://www.shooltz.com

There are more than one way to get it working. Using EM_SETSEL is another method. I recommend trying that method to see if get the design where you want it. Kuphryn

And what do you think CEdit::SetSel does? Tomasz Sowinski -- http://www.shooltz.com

Just FYI, CEdit::SetSel is a thin wrapper which sends EM_SETSEL. So there's no difference, unless you want to achieve macho-API posture. :) Tomasz Sowinski -- http://www.shooltz.com

Two things: First (as I go into Pedantic mode...) Anonymous wrote: CEdit* ped=(CEdit*)GetDlgItem(IDC_EDIT_ap1); ped->SetSel(0, -1, FALSE);    I would recommend that you do not get into the habit of casting the return value of GetDlgItem(...) to a CEdit* (or other class type) like that.  There are certain situations where GetDlgItem(...) will return a pointer to a real CEdit (or other Control Class) object, but if you do not know what those situations are, it is best to avoid this entirely.  Bind a CEdit member variable to the control, and use it instead.    True, in the case of MFC, doing that is usually safe, but in general C++ practices, it is a bad thing to do: you do not know if the pointer returned by GetDlgItem(...) is, or ever was, a pointer to an actual CEdit object.    Second, try using PostMessage(...) to send yourself the EM_SETSEL message from inside the OnSetFocus handler.    BTW: CWnd::OnSetFocus(...) is a standard function.  What is OnSetfocusEDITap1 supposed to be?  You may be handling the WM_SETFOCUS message incorrectly.    Peace! -=- James.

but there's no message like GetFocus, (I look it up in class wizard)

yeah, I thought there must be sth wrong with the function OnSetfocusEDITap1,I thought may be there is a function named OnGetFocus...., but I failed to find it. Have you met this question?
