Easy question!

Hello:
I use vc++6.0 MFC.Built A Dialog class .
Now I add a CEdit.I want change the value
in CEdit .Which function can do it?
Welcome any advice!
Thanks!

There are a couple of ways to accomplish this.

1) Add a member variable of type CString to your dialog for the CEdit you just added. (with Classwizard). Then just set the text you want and call UpdateData(FALSE); FALSE - updates the controls TRUE get values from controls

2) Add a member variable of type CEdit with Classwizrd and use m_myEdit.SetWindowText("TEXT");

3) use GetDlgItem(IDC_YOUREDIT_ID)->SetWindowText("TEXT");

HTH,

Thank you:
Like your advice.(I created Dialog-base application)
(1)I added a member variable of CString is m_name.(Use it change value)
(2)I Add CEdit m_Edit.Add m_Edit.SetWindowText("TEXT")
and GetdlgItem(IDC_my)->SetWindowText("TEXT") in OnInitDialog()
When I run the result:First display "TEXT" in CEdit.
But When I change the value use m_name.But the display
not change.I add UpdataData(TRUE);The run is error(UpdataData no define);

Could you help me?
Thanks!

If you defined a variable associated with your edit is not necessary to use GetDlgItem or a variable of type CEdit.
If you need to take text from edit ctrl and put hem in your variable do this:

UpdateData();



If you need to take text from your variable and put him in your edit ctrl do this:

m_name = "New value you want";
UpdateData( FALSE );





That's all.
Let me know if this help u
