Comprehensive discussion: http://dotnetperls.com/whitespace this is all C# easily converted to VB.Net with online tools.
Here's VB.Net and this example is very thorough.
http://www.dreamincode.net/code/snippet3423.htm
This article takes a fairly in-depth look at strings. Ideally you'd want to parse the string a number of ways. Looking for " " a space the ASCII characters for space, tab and return and then you'd want to also search for "\r", "\s", "\n" and "\t" you could of course use RegEx as well.
Here is a bunch of solid examples from Google with this search term:

Hi Fordraiders,
I'm not sure exactly what your code is trying to accomplish, but based on your question/request you might want to try working this into your code.
If you want to eliminate all characters except numbers, letters and spaces (but trim leading and trailing spaces) try this:
FldPositionTextBox.Text = System.Text.RegularExpress
FldPositionTextBox.Text = System.Text.RegularExpress
If you want all "printable" characters and spaces (but again trim all leading and trailing spaces) try this:
FldPositionTextBox.Text = System.Text.RegularExpress
FldPositionTextBox.Text = System.Text.RegularExpress
Please note that the second line in each example replaces multiple spaces with a single space. There may be a more elegant way to do this in Regex but at least this will get you going. If I understood your request correctly, you seemed to have been pretty close with your Regex line that was commented out.
Again, I hope that I understood your request correctly and I hope that this helps. :)

fordraiders, when you say "extra spaces", we are interpreting this to mean that single spaces are ok but "extra" i.e. duplicate spaces are not... " " ok but " " not ok. Is that correct? If so, HumbleBeginnings' response will do what you ask.
If you want to remove all spaces, then change
FldPositionTextBox.Text = System.Text.RegularExpress
to
FldPositionTextBox.Text = System.Text.RegularExpress
By the way, this block of code:
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
can be shortened to:
If Regex.IsMatch(FldCompartme
or if you prefer:
If FldCompartmentTextBox.Text
in fact, since you've just assigned the value of FldCompartmentTextBox.Text
If value > 0 AndAlso value < 10 then FldCompartmentTextBox.Text
If you want to remove all spaces, then change
FldPositionTextBox.Text = System.Text.RegularExpress
to
FldPositionTextBox.Text = System.Text.RegularExpress
By the way, this block of code:
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
If Me.FldCompartmentTextBox.T
can be shortened to:
If Regex.IsMatch(FldCompartme
