Trimming unwanted characters from a string
Hi,
I am trying to remove non alpha-numeric characters from a string extracted from a Word 97 document in my VB project.
I used OLE to read a Word file then extract let's say sentence number 3 from the open document.
The text box that displays the content of that sentence shows a little square as the rightmost character.
Is there a function I can use to trim that little square from the string??
Regards

How about:
Public Function RepStr(Text as String) as String
dim filter as string
dim work as string
dim char as string
dim index as integer
work = ""
filter = "ABCDEFGHIJKLMNOPQRSTUVWXY Zabcdefghi jklmnopqrs tuvwxyz012 3456789"
for index = 1 to len(text)
char = mid(text, index, 1)
if instr(char, filter) then work = work & char
next index
'
RepStr = work
End Function
This method has the advantage of allowing explicit control over that gets accepted. You can add selected punctuation and other symbols as well as the standard character set.

Hi,
We had a similar problem and this seemed to work.
This function replaces the line feed character with a carrige return line feed character.
Hope this helps you.
Public Function Replace(sString As String) As String
Dim Maxlength As Integer
Dim CurrentPos As Integer
Dim sNewString As String
Maxlength = Len(sString)
CurrentPos = InStr(1, sString, Chr(10), 1)
While (CurrentPos > 0)
NewString = Mid(sString, 1, CurrentPos - 1)
sNewString = sNewString & Chr(13) & Chr(10)
sNewString = sNewString & Mid(sString, CurrentPos + 1, Maxlength - CurrentPos)
CurrentPos = InStr(CurrentPos + 2, sNewString, Chr(10), 1)
sString = sNewString
Maxlength = Len(sNewString)
Wend
Replace = sString
End Function

Waty,
Your second function works.
It leaves out one non-alpha-numeric (on some sentences there was up to 4) so I used something like:
if asc(right(sentence,1))=13 then sentence=left(sentence,len (sentence) -1) it it seems to work beautifly.
Excelent help thank you!
