check for decimal in numerical string

[kani98]

I have an input box that a user can enter in 4 characters like 1.34. I need to check if there is a decimal in the input string and truncate everything after the tenth place. Is there a C/C++ function that I can use for this? Thanks

will CString :: Find help you?

Using "Add memmer variable wizard", add a variable (Category=value) and set ‘Max chars’ to n. Or, DDV_MaxChars(pDX, yourVar, 10); -- modified at 3:50 Saturday 10th November, 2007

How does that find the "decimal in the input string and truncate everything after the tenth place"??? Mark

Check out strchr(), or string::find(), or CString::Find().

Is there a C/C++ funciton that will remove a character from a string? I want to remove the decimal from the input string. If someone enter 1.23, I want to use only 1.2, remove the decimal making it 12.
