Another RegEx would do this easily. All you have to do is match any character that is not acceptable and call the Replace method on the RegEx object. The match would probably be something like "\W" and the replacement string would be an empty string.

Google for "Expresso RegEx" and you'll come up with a very nice tool to help you with this.

Pattern for only numericals

Hi,

Can anybody please check and clear any problem exists in the below code. My actual requirement is I get values as "900.09" and "90009", but I have return "90009" as numeric and "900.09" as non-numeric.
I am not getting the pattern or may be my testing senario is wrong please clear me this as I am new to VB 6.0.

With objRegExp
        .Pattern = "\d" '"[0-9]"
        .IgnoreCase = True
        .Global = True
    End With
      
    If iLen > 0 Then
         If (objRegExp.Test(sTemp) = True) Then
            IsNumericOnly = True
         End If
    End If

Thanks,

Aleem Mohammad.

Quit spamming the board. You've already asked this question below.

If this vb6 code or .Net?

Judging from your previous posts, why do you even need a RegEx?? Try to convert the string to a Double, or some other appropriate numeric type. If the conversion works, the string was valid, if not, it'll throw up an error, so use an "On Error" to catch this and react appropriately.

Hi,

Will this work, may be not because I have to separate only the integers not even floats or doubles. Thats why choosen Regular expression.

You really have a problem with specifying your requirements. As I counted, this is the third time you've changed them.

In that case, since you're need the number to be only integers, it appears that you've already got the RegEx correct, or maybe you need to specify that you're looking for 'x' number of digits in a row. Maybe this field needs to be a 5 digit number at all times?? In that case, the expression would be something like \d{5}. Or, it's the rest of the code that's bad, but since you haven't posted the entire function, nor given a complete description of your requirements and input samples, it's very difficult to say.

Also, you say you're NEW to VB6?? Did you know that VB6 is now a dead technology?? Microsoft stopped supporting it a while ago and there will be no future support for running VB6 apps in Windows 7 and beyond.

Unexpected Error(32810) while compiling a VB 6.0 Project

Hi.

I have an issue with VB 6.0 Binary Compatibility. I have one dll (Let's say a.dll which is in VC++) and another VB Activex Dll (Let's say b.dll) is using a.dll. b.dll is binary compatible.

I have made small changes to the a.dll and i have referred to the new version of a.dll in b.dll project. Now when I try to compile I get an error "Unexpected Error (32810)".

I have spent lot of time on this and unable to find out the root cause. Can anybody please explain the issue and solution for this issue.

Best regards
Shankar

i think u have to re-register the a.dll
use regsvr32 <dll name="" with="" path="">
before that ensure that your a.dll is successfully compiled in th vc++.

Regular expressions are ways of matching patterns in text, validating formats, and sometimes extracting specifically formatted information.

Hi,
Can u please help me in resolving it, I have a some 100 strings of numerical values. some will like "900.09" and some will be like "90009".
Then I should take values like "90009" as numerics and return "True" and if any char other than that and like this "900.09" as non-numeric return 'False".

I have written code as below, but they are saying that it is performance issue. Can u help me in writing it by using Regular expressions.

sTemp = TestString
    iLen = Len(sTemp)
    If iLen > 0 Then
        For iCtr = 1 To iLen
            sChar = Mid(sTemp, iCtr, 1)
            If Not sChar Like "[0-9]" Then Exit Function
        Next
    'If IsNumeric(sTemp) = True Then
        'If Not sTemp Like "[0-9]" Then MsgBox "Hi"
    'End If
    
    IsNumericOnly = True
    End If

Thanks a Lot,
Aleem Mohammad.

The keyword "Like" in VB actually is a very weak form of regular expression. The performance problem here is that you are iterating through every single character. With a proper regular expression you can match against the whole string in one go.

You need to create a new Regex object, and set it up with the required pattern string.

then you can call Match on the regex object and check the Success flag.

To work out the pattern string you need to use, look at the MSDN link I provided in my last reply.

You can find a reference to the regular expression pattern language here[^]

Also, try working through this tutorial[^] to start you off.
