Problems with CInt [RESOLVED]

Code:

---

    Const bibble As String = "a"
    Dim number As Integer
    number = CInt(bibble)

---

This code crashes the program. Is there a function that would do the same thing as CInt, but not make the program crash?

Crashes? Do you mean an error occurs? The error makes sence since you can't get an integer from a letter. What are you trying to accomplice?

Are you looking for the ascii value? Asc(bibble) should give you 97. Otherwise "a" has no integer meaning.

I am taking in user input. The user input should be an integer. The problem is that I cannot assume that the user input will be numerical.

I need a function that could take in string input and convert to an integer without crashing the program if the input is invalid. If there is no such thing, is there a function that can tell me if the string that I have is numerical?

Code:

---

number = Val(bibble)

---

will convert the value entered into a numeric - if its text it will return a zero value.

I might be mixing up my versions of VB, working in 4 of them, but you could look up IsNumeric() or similar.

The IsNumeric() just tells you if it has only numbers or not. Val() gives you only the numbers ;)

True, but maybe 0 is a valid entry, so Val() wouldn't help him in the case:

But there is such a thing... Val() does that... :confused:

Thanks. IsNumeric() worked!

Thank for the help! :)
