Replacing a character at the start of a line in txt

How can I search a txt file line per line and check if the line starts with the character "#".And since I have found that character,how can I erase it or just replace it with " ".Here's a sample text:

# The index.html.var file (a type-map) is used to deliver content-
# negotiated documents. The MultiViews Option can be used for the
# same purpose, but it is much slower.
#
DirectoryIndex index.html index.html.var
#
# AccessFileName: The name of the file to look for in each directory
# for additional configuration directives. See also the AllowOverride
# directive.

If Left(theStr, 1) = "#" Then
'found it
End If

fixStr = Mid(theStr, 2, Len(theStr))

Thanks for the tip my friend!I only have one question:what's the fixStr stand for,as a function I mean.And what is included in the "if" loop,except the comment?Thanks again!

fixStr is just a variable name I made up.

You'd probably want to put the code to remove the # in the If block.

In case I want to check each line if it begins with the "#",how can I go from the first line to the second,the third etc...?

Depends on what code you're using to get the lines to check. Post some code maybe?

Private Sub Option1_Click()
Dim rline
Dim Counter As String
Dim searchar
Dim chk
searchar = "#"
chk = InStr(0, rline, searchar)

Open testfile For Input As #1 'Open the text file
Line Input #1, rline 'grab first line
Debug.Print rline
Counter = 1 'start counter
Do While Not EOF(1) 'Continue to EOF = true

If Counter = 1 & chk = 0 Then
Text1.Text = rline
Else
'No
If chk <> 0 Then
Counter = 0 'reset the counter
Text2.Text = rline
End If
End If
Line Input #1, rline 'Get next record
Counter = Counter + 1 'Increment counter
Loop
Close #1

End Sub

The code above seems to read only the last line before the end of the file,although if it worked properly,it should read each line seperately.If at the start of the line grabbed,the "#" character is spotted,the string that follows is sent into a textbox.If there's no "#" at the start of the line,the following string goes to another textbox.How is it possible to make the program read each line of the textfile loaded seperately,check if the starting character of each line is "#" and then store or just view the following strings?Help....

You are setting chk before you read the line. Move that test after you have read the line.
