I would appreciate it if someone help me with the VB code (very limited knowledge of VB).  I have a file which has many lines and each line has information as follows:

xxxxxxx|xxxx|AAAAA|BBBB|


I would like to

1. Change the first pipe sign (|) into hypen (-)
2. Remove the last pipe (|) of each line
3. Change the second and third pipe (|) into semi-colon

Thank you.

You can try this code:
Dim OriginalString As String = "xxxxxxx|xxxx|AAAAA|BBBB|"
Dim ReplacedString As String = Replace(Replace(Replace(OriginalString, "|", "-",1,1), "|", ";",1,2), "|", "")

Hello,

here is the code which will look at your folder and take the file "test" check if file exist and then replace the string and create new file ...

dim folder, input, output, fsObject, fObject_in,fObject_out, line

folder="c:\database"
input ="test.txt"
output ="out.txt"

Set fsObject=CreateObject("Scripting.FileSystemObject")
if fsObject.FileExists(folder & input)=false then
   wscript.echo "File not present"
   wscript.Quit
end if

Set fObject_in = fsObject.OpenTextFile(folder & input, 1)
set fObject_out = fsObject.CreateTextFile(folder & output, TRUE)

Do Until fObject_in.AtEndOfStream
line= fObject_in.ReadLine

line=Replace(line,"|","-",1,1)
line=Replace(line,"|",";",1,2)
line=Replace(line,"|","",1,-1)
 
 fObject_out.WriteLine line
Loop

fObject_in.Close
fObject_out.Close

Open in new window

You will need to save that as a VBS file, say EE28561925.vbs, adjust the folder / file names near the top if needed, and then at a DOS command line (or in a BAT file) do the following:

cscript //nologo EE28561925.vbs

Hello,

can you run the file attached, but before you run it you need to change few lines i.e.

folder="c:\database" you need to put the exact location of the folder containing the files in which you want to replace the string

input ="test.txt" in this line you need to put name of your file


output ="out.txt" in this line you need to put name of RESULT file i.e. file where the replaced content will be saved.

then save the edited file to some location for example c:\test\replace.vbs then open command prompt and change directory to c:\test and then just write replace.vbs and if any errors post it...


I attached how the command prompt shoul look like, and since i do not have folder C.\database i got the same error...

I think this is the issue,

instead of line  folder="c:\database" put this folder="c:\database\"
