List function names from DLL file

Recommended Posts


Here is my new little function called _DLLGetFunctionNames. It extracts the dll function names from dll files.

It's not perfect, but it works good.

I hope you like it.

Greetings from Austria!

#Include <Array.au3>

$DLLFile = FileOpenDialog("Choose DLL file", @SystemDir, "DLL files (*.dll)", 3)
if @error Then Exit

$aNames = _DLLGetFunctionNames($DLLFile)
If @error Then Exit ConsoleWrite($DLLFile & ": Fault " & @error & @CR)

;~ $sNames = _DLLGetFunctionNames($DLLFile, 1)
;~ ConsoleWrite($sNames & @CRLF)

_ArrayDisplay($aNames, StringTrimLeft($DLLFile, StringInStr($DLLFile, "\", 0, -1)))

Func _DLLGetFunctionNames($sFileName, $ParamResult = 0)
;funkey Aug, 12th, 2010
;$ParamOutput: 0 --> Result is array
;    1 --> Result is string
Local $hFile = FileOpen($sFileName, 0)
If $hFile = -1 Then Return SetError(1) ; file error
Local $sFile = FileRead($hFile)
Local $iStartPos, $iEndPos, $sFunctionNames, $aFunctionNames
Local $DLLName = StringTrimLeft($sFileName, StringInStr($sFileName, "\", 0, -1))
For $i = 1 To 99
  $iStartPos = StringInStr($sFile, $DLLName & Chr(0), 0, -$i)
  If $iStartPos = 0 Then Return SetError(2) ;search error
  $sFunctionNames = StringTrimLeft($sFile, $iStartPos - 2)
  $sFunctionNames = StringTrimLeft($sFunctionNames, StringInStr($sFunctionNames, "dll") + 3)
  $iEndPos = StringInStr($sFunctionNames, Chr(0) & Chr(0))
  $sFunctionNames = StringLeft($sFunctionNames, $iEndPos - 1)
  If StringInStr($sFunctionNames, Chr(0) & Chr(0x90)) Then $sFunctionNames = StringLeft($sFunctionNames, StringInStr($sFunctionNames, Chr(0) & Chr(0x90)) - 1)
  $aFunctionNames = StringSplit($sFunctionNames, Chr(0), 2)
  If UBound($aFunctionNames) > 0 And StringStripWS($aFunctionNames[0], 8) <> "" Then ExitLoop
Switch $ParamResult
  Case 0
   Return $aFunctionNames
  Case 1
   Return StringReplace($sFunctionNames, Chr(0), @CRLF)

Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.

Interesting approach. If you want to get the list the right way though (and with more info), check out my UDF: File + Process Imports/Exports Information
