How to set only integer value property for an edit control

[BiswaR]

Hi Guys, I have added one edit control to a dialog and attached a string variable to that. But i want only integers can be entered to the edit control and not characters.(N.B. I have attached a string variable to that edit control because i want that value to be received as string. Please help.

Subclass CEdit and handle WM_CHAR message. If the char entered is a valid number then call base class implementation else you can ignore the char.

Instead of creating the control variable of edit box as string, use integer type. if u wan to get the number as string just use the "Format" function of the CString. Then set Number (ES_NUMBER) style of the edit box, which only allows interger to enter. nave

There is another way toooooooo Add the Number style to Edit. Whenever you want text in the edit box, Just call GetWindowText() :) nave

on the resource editor, there is a "decimal" property which make the editBox accept only the 10 decimal digits... if you'd like to allow the . character, or a sign character like **+** or **-**, you'll have to overload the WM_CHAR event...
