Is Valid Regular Expression

what u dont want in the expr. to be regular ? what do u want to check exactly ..

any data in vb can be taken as string if it's not out of memory , so please explain what do u want the string format be .

unfortunately I can't understand u again , what flag makes your string not "Regular Expression" ??

if string = "My name is the name of my father's son" this will be "regular" ? so what will not be regular ? using what in the string will not make it "regular" that's what I want to know .

If u wish have a sample for "find and replace" u may look in this :

Dear Amahdy,
I am using a rich text box notepad.Now I want to implement a Find and replace method by using the Regular expression. I am using this method

Dim CountallRegexp As New RegExp
Dim mc As MatchCollection
Dim mat As Match
CountallRegexp.Pattern = sFind
CountallRegexp.Global = True
If ChkMatchCase = vbChecked Then
CountallRegexp.IgnoreCase = False
Else
CountallRegexp.IgnoreCase = True
End If
Set mc = CountallRegexp.Execute(frmMain.ActiveForm.TestRTB.Text)


If the regular expression check box checked and when the user enters any special charcters like "$$$$%$%$^", this method gives a run time Error?/How to solve this problem?
Thanks in Advance.
