Thanks that looks like it could work.
If any one else can find a better way i'm open for more suggestions!

.NET or not .NET? MFC is the question......

All,

I am loading a string into a CEdit box and want the cursor at the EOL so user can immediately add text.

When I try to use CEdit member function to do this, compiler complains that my variable is a CString type - which of course it is.

Have studied "Using the CEdit control" By Wolfram Steinke but can not duplicate how he assigned 2 variables (a CString type AND a CEdit type) to the same edit box.

Any help would be much appreciated!

Create your member variable of CEdit type - MFC Wizard "Add Member Variable" dialog has "Variable Type" combo for this. You can also keep two variables of different types for one control.

Thanks Alex,

I've got that working (thank-you!), but there still seems to be a "trick" I am missing.

If I write a simple test program that writes to and reads from an edit control, everything seems to work fine.

My "control CEdit" variable is: mc_editkey

=== for example, the following works fine:

mc_editkey.SetWindowText("some stuff");
int len = strlen("some stuff");
mc_editkey.SetSel(len,len,FALSE); //need to put cursor at end
mc_editkey.SetFocus();
UpdateData(FALSE);

===this seems to work fine also;
UpdateData(TRUE);
mc_editkey.GetWindowText(buf, bufmx);

But at other times, the SetWindowText() function does not seem to work and also any attempt to force the cursor to the end of the line also does not work.

Are there any tricks to getting the control to "pay attantion to me"?
Is it possible to issue UpdateData(FALSE) at the wrong time or too many times?

I think there is something(s) fundamental I am missing. For example when the Diaolog Box pops up I want the focus to be in the edit box, i.e. I want the cursor to be there. So in the OnInit function I issue:

mc_editkey.SetFocus();
UpdateData(FALSE);

But it never works.

Much thanks in advance,
Robert

UpdateData doesn't matter for variables of type Control such as CEdit, CComboBox etc., it works for variables of Value type such as CString, int... To set focus on dialog control use CDialog::GotoDlgCtrl. Don't forget also to set Tab Order in dialog resource editor (Layout menu).

Thank-you again Alex,

I pretty much have it working. Smile | :)

In the syntax for CDialog::GotoDlgCtrl it asks for CWnd* pWndCtrl as a function parameter.

I confess that I'm not sure which variable to use.

Best to you, Thanks again,
Robert

Write GoToDlgCtrl(GetDlgItem(nID)) or use variable of control type (CEdit etc.): GoToDlgCtrl(&m_edit_box).

Hi Robert!

I have encountered the same problem, specifically when subclassing the control.
See this thread.
SetWindowText() does not work well for me,
so I resorted to using ReplaceSel() instead.

To move the caret to the end, try:
mc_editkey.SetSel(0, -1);
mc_editkey.SetSel(-1, -1);

Now, use ReplaceSel to append text:
ReplaceSel(buf);

In your case, I think it might be enough with ReplaceSel(), since it should move the caret to the end.

There is no need to use UpdateData(), it will work anyway.
Do you return FALSE from OnInitDialog()? You must do that when setting the focus on a control. See CDialog::OnInitDialog in MSDN.

Cheers,

/Fredrik
