How can I add to TextBox??(MFC)

-
If I have a dialog box that contain textbox and botton .. I want the botton, when I press it, add letter to the textbox.

If you saw the Windows Calculator . When you press [1] botton it add '1' to the text box... How can I make this..

--------------------------------
this is the (OnBottonPress) function that I made:

CMyDialog dlg;
dlg.TextBox=dlgTextbox+'1';
---------------------------------------
But no thing happen?!

in your resource file

Code:

---

#include "Resource.rc"
#define IDC_STATIC

IDI_DIALOG DIALOG DISCARDABLE 0, 0, 100, 100
STYLE DS_MODALFRAME | WS_SYSMENU | WS_POPUP | WS_CAPTION
CAPTION "Sample Dialog"
FONT 9, "Book Antiqua"
BEGIN
    GROUPBOX          "Hey......", IDC_STATIC, 3, 3, 90, 90
    PUSHBUTTON        "Press OK!", IDOK, 7, 7, 50, 50
    CTEXT                  "This is probably the text you were trying to do!!!", IDC_STATIC, 7, 53, 50, 20
END

You were trying to do that right?

Read the existing text from the edit box with GetDlgItemText(), (or similar), use strcat() to append the new character, then SetDlgItemText() to put the new string back.

yea, what he said......

thank you all.. the problem have been solved ...

I used the GetDlgItem() and the SetWindowText() Functions to do.

thank you again
