Assigning an Character

[anil]

Hi everybody,

I have some n number of Names, the string i am declaring should take
any names,

for Ex: As for searching any file we use "*.*" is there any thing
simillar to this that i can use in VB code to specify any string.

Thanks & Regards

You can use the LIKE operator on strings:

If value Like "AB###" then ok = True

? = single character, * = 0 or more characters, # = single digit

You can include or exclude characters in the search by inserting a list
enclosed in a pair of sq brackets.

You exclude with !

If value Like "[A-C]####" then ok = true --1st is A B or C, then 4 digits

If value like "[!A-C]####" then ok = True --1st is not A or B or C, then
4 digits

Look for only alpha characters: If Not (value like (*[!A-Za-z]*")

Look for only digits: If Not (value like "*[0-9]*")

Look for any character but no consecutive punctuation symbols:

If Not (value Like "*[:;.,][:;.,]") then ok=true

This is faster than regex, but slower than manually comparing strings.

HTH,
Robin S.

Sounds like a pattern-matching issue to me:

The VB "Like" operator works as ever it did

? ( "Anil" Like "A*" )
True

Or you could delve into the murky depths of Regular Expressions

Imports System.Text.RegularExpressions

Dim re as New Regex( "^A" )
? re.IsMatch( "Anil" )
True

Is there a pattern that will check a possible full path

C:dir1\dir2...\name.extension

to see if it is a valid string for the file system?

Thanks

That sounds like a question for the Regular Expressions experts. Anyone?
