Solution 1

Use the following code

C#

string s1 = "GHGHGHJJH1238";

          int x = Int32.Parse(s1.Substring(s1.Length - 4, 4));
          MessageBox.Show(x.ToString());// show message or whatever you want

Best of luck;

Dear Mantu,

Thanks for the reply......How do you think the code that you sent will work....Actually its throwing errors like

---->'Int32' was not declared in this scope

---->'class QString' has no member named 'Substring'

---->'class QString' has no member named 'Length'

---->request for member 'ToString' in 'x', which is of non-class type 'int'

Actually SubString is not supporting donno why.........Any solution would be appreciable.....Thanks in Advance...
