Check Numeric value

[garfield185]

How can I check if the text inside a CEdit is numeric? I mean: "2355345" Yes "3452fsgd" No "fsdgsdg" No "sds334" No I usually use the IsNumeric () function but it seems that in Visual C++ is not available... Can somebody help me? :(

You can choose to let the user enter only the numbers . Right click the edit box and set the number property to true. So in this manner the user won't be able to enter any text in the edit box(except number)

Somethings seem HARD to do, until we know how to do them. ;-)_AnShUmAn_

If you just want to allow only numeric value in the Edit Box, Go to property window and Set the Number property to True. Or If you want to validate it after user have entered the character, use Dailog Data Exchange (DDX) and Dialog Data Validate (DDV) in DoDataExchange(CDataExchange* pDX) function. Else Scan the text and use isdigit() for each char. If any one have better solution, pls let me know.

Gosh!! Thank you very mucho to both of you. As _AnShUmAn_ says, "Some things are hard to do UNTIL WE KNOW HOW TO DO THEM". That´s true... :-O

Try to use CRT function isdigit() or Windows API GetStringTypeEx().
