Strip Leading and Trailing spaces - Vba

Hello,

I have some lines in my word document, which when viewed with bookmarks turned on, has a string of continuous leading or trailing spaces.(which I believe is created by pressing continuous spacebars).

One example of a line is:
==================================

                                           provided at the end.

==================================
The text  and the paragraphs in the document are aligned properly, pagemargins are fine. The only thing that annoys is these leading or trailing spaces. This annoys because we use these rtfs to another application and there these lines mess up.

Therefore I was wondering is there a macro or a vba code that can eliminate these leading or trailing spaces, and the text intend or alignment should not change by removing them. I would very happy if there is a way to convert these spaces to tabstops or so.

Anyway, a vba code to strip the leading and trailing spaces without having any impact on the format of the document, would help me greatly.

Thanks

this is what i've got so far:
Sub ta()

Dim X As Long
Dim y As Long
Dim Blan As Boolean
Blan = True
X = 0
Selection.HomeKey unit:=wdStory
Do While Blan = True
    Selection.MoveRight unit:=wdCharacter, Count:=1, Extend:=wdExtend
    If Selection = " " Then
        X = X + 1
        Blan = True
        Selection.Collapse direction:=wdCollapseEnd
    Else
        If X <> 0 Then
            Blan = False
            Selection.MoveLeft unit:=wdCharacter, Count:=1, Extend:=wdMove
            y = Selection.Information(wdHorizontalPositionRelativeToTextBoundary)
            Selection.MoveLeft unit:=wdCharacter, Count:=X, Extend:=wdExtend
            Selection.Delete
            Selection.ParagraphFormat.TabStops.ClearAll
            Selection.ParagraphFormat.TabStops.Add Position:=y
            Selection.TypeText vbTab
        End If
        Selection.EndKey unit:=wdLine, Extend:=wdMove
            Selection.MoveRight unit:=wdCharacter, Extend:=wdMove
        X = 0
        y = 0
    End If
    Selection.ParagraphFormat.TabStops.ClearAll
    Blan = True
Loop



End Sub

it goes through (looping line by line,counting character by character) until it finds a nonspace, then it measures how far it is to the text boundary, then it removes the spaces, sets tab stop that far and put in a tab. Then it hops to the next line.
I tried it, and it seemed to work on my test case but I haven't tested much.  Don't know if there's a better way (I never worried about spaces before).  It doesn't do trailing spaces, but the same concept of counting should work there ( just won't need to have a tab). I'll look at this some more later, but that's what I've got for you now.

gilbar,

The code seems to be working, but it goes into an infinite loop after executing for the last line...
Any clues.

Thanks

oops! knew i'd forget something
replace
Selection.MoveRight unit:=wdCharacter, Extend:=wdMove  
with
If Selection.MoveRight(unit:=wdCharacter, Extend:=wdMove) = 0 Then Exit Do

(that's in the else section )

so  the whole thing should be like
Sub ta()

Dim X As Long
Dim y As Long
Dim Blan As Boolean
Blan = True
X = 0
Selection.HomeKey unit:=wdStory
Do While Blan = True
    Selection.MoveRight unit:=wdCharacter, Count:=1, Extend:=wdExtend
    If Selection = " " Then
        X = X + 1
        Blan = True
        Selection.Collapse direction:=wdCollapseEnd
    Else
        If X <> 0 Then
            Blan = False
            Selection.MoveLeft unit:=wdCharacter, Count:=1, Extend:=wdMove
            y = Selection.Information(wdHorizontalPositionRelativeToTextBoundary)
            Selection.MoveLeft unit:=wdCharacter, Count:=X, Extend:=wdExtend
            Selection.Delete
            Selection.ParagraphFormat.TabStops.ClearAll
            Selection.ParagraphFormat.TabStops.Add Position:=y
            Selection.TypeText vbTab
        End If
        Selection.EndKey unit:=wdLine, Extend:=wdMove
         If Selection.MoveRight(unit:=wdCharacter, Extend:=wdMove) = 0 Then Exit Do
        X = 0
        y = 0
    End If
    Selection.ParagraphFormat.TabStops.ClearAll
    Blan = True
Loop



End Sub

if it's at the end, the moveright can't move so it returns zero so then it exits the loop.

Works great, gilbar. Thanks for the vba code. I will work on the trailing spaces.
