[beginner85]

Hello all, i try to do a script return a string between 2 key word :

$file = FileOpen("temp.db", 0) 
If $file = -1 Then     
  MsgBox(0, "Error", "Unable to open file.")     
   Exit 
EndIf 
For $line = 300 To 320     
   If StringInStr(FileReadLine($file, $line), "IFRAME style='PADDING-TOP: 10px' height=650 src='") Then
          
     $code = _StringBetween(FileReadLine($file, $line), "IFRAME style='PADDING-TOP: 10px' height=650 src='", "' frameBorder=0 width='100%' name=")         
     $Online = $line     
     
   EndIf 
   Next 
FileClose($file) 
MsgBox(0, "Details", " On line " & $Online & "  value = " & $code)

It show the line content string i want to return, but the value is nothing. I don't know where wrong, please help me. Thank you

If you read the helpfile entry for _StringBetween, You would see:

Success: Returns a 0 based $array[0] contains the first found string.

So Try this code below

$file = FileOpen("temp.db", 0) 
If $file = -1 Then     
  MsgBox(0, "Error", "Unable to open file.")     
   Exit 
EndIf 
For $line = 300 To 320     
   If StringInStr(FileReadLine($file, $line), "IFRAME style='PADDING-TOP: 10px' height=650 src='") Then
          
     $code = _StringBetween(FileReadLine($file, $line), "IFRAME style='PADDING-TOP: 10px' height=650 src='", "' frameBorder=0 width='100%' name=")         
     $Online = $line     
     
   EndIf 
   Next 
FileClose($file) 
If IsArray($Code) then
MsgBox(0, "Details", " On line " & $Online & "  value = " & $code[0])
Else
Msgbox(0,"Error", "Error: No String Found.")
EndIf
