Solution 1

Try:

C#

Regex regex = new Regex("[a-zA-Z]");
string result = regex.Replace(InputText,"#");

Get a copy of Expresso [^] - it's free, and it examines and generates Regular expressions.

im just using a Microsoft word. The find and replace.
without using the "replace with:" field
what regular expression should i use?
i need to modify the [a-zA-Z] in order to get the right output.
Thanks a lot.

If you are using Word, and want a Word specific reply, then you have to tell us that!

Read this: http://office.microsoft.com/en-us/word-help/find-and-replace-text-by-using-regular-expressions-advanced-HA102350661.aspx#_Toc286834986
It may help.

iv been here but this site is using "replace with" field. but thanks for the effort. . .i appreciated it. ^^

Yes. "Replace with" "#" I suspect...

anyway what if i want to replace the two ## into #
the output will look like this
123456789######987654321####12345#123

Then you need to run a different regex, probably after the first (or the regex gets horribly complicated, and a too easy to get wrong). To change exactly two '#' characters into one:
(?<=\d)\#\#(?=\d)
(Match prefix, single digit, exclude.
Match two '#' characters
Match suffix, single digit, exclude)

Seriously, get Expresso - it can make this stuff a lot easier! I really wish I'd written it...
