Just need to replace space character with underscore character in string.

I have tried:

MyString.Replace(" ", "_")

And that doesn't seem to have any effect, but doesn't throw any exceptions or errors either.

I don't have docs in front of me, and your example looks right,

Are you sure the order is correct (ie its not "_", " ")  is it?

Lastly I once had something like this, turned out the character was not actually a space (I think space is ascii 32, this one was like 169 or something!)

So if worst comes to worst, loop through each char in your stirng and print the ascii value to confirm you have a space.

Replace is a function:
  MyString = MyString.Replace(" ", "_")

More to the point, Strings are imutable. So a function will never modify a string, it will usually return a modified copy of the string which you need to capture and/or use.

just try this

mystring = Replace(ChrW(32), "_", mystring)
or
mystring = Replace(" ", "_", mystring)
