[Question] How to get Data from Edit Class

[mecheil.edwar]

I Have two questions Regarding to Edit Class :

Q1: If I want to input only integer Number to Edit Class. how can I Prevent user to input characters to Edit Class
Q2 : How can I get data Input to Edit_Class
Simply my Application is to create Edit_Classes to Let user provide the application Numbers

Thanks & Regards

Handle WM_CHAR message and check if the inputted character is a digit or not.
You should also handle the case of a negative numbers if they are allowed: it means that the "minus" is allowed only as the first symbol in the control.

A1: ES_NUMBER
A2: GetDlgItemInt

Only handling WM_CHAR is most likely not enough, you will also have to handle WM_PASTE.

Thanks to all for their effective replies,
But still I have problem to get Real Number (as Example 23.334)
If I can get any sample Example It will be better to clear using concpet
