LoadLibrary Help

[KiZsLeG 0]

Hello Guys, 

Just want to ask for help or guidance on why DllCall doesn't work with LoadLibrary but it works using the function _WinAPI_LoadLibrary.

What's wrong with my DLLCall.

#include <WinAPI.au3>


;local $module = _WinAPI_LoadLibrary("user32.dll") ; Working

Local $module = DllCall("Kernel32.dll", "Ptr", "LoadLibrary", "Str", "user32.dll") ; Not Working

if ($module) Then
   msgbox(0,"Success","Success!")
Else
   MsgBox(0,"Failed", "Failed!")
EndIf

Thanks,

You need to extend the error checking of your script.

What is the value of @error after DllCall?

The value is 0 sir.

The DllCall function returns an array.

#include <WinAPI.au3>

Local $module = _WinAPI_LoadLibrary("user32.dll") ; Working
ConsoleWrite($module & @LF)

Local $module = DllCall("Kernel32.dll", "Ptr", "LoadLibrary", "Str", "user32.dll") ; Not Working
ConsoleWrite($module[0] & @LF)

If $module[0] Then
    MsgBox(0, "Success", "Success!")
Else
    MsgBox(0, "Failed", "Failed!")
EndIf

As DllCall returns an array I would check for an array:

#include <WinAPI.au3>

Local $module = _WinAPI_LoadLibrary("user32.dll") ; Working
ConsoleWrite($module & @LF)

Local $module = DllCall("Kernel32.dll", "Ptr", "LoadLibrary", "Str", "user32.dll") ; Not Working
ConsoleWrite($module[0] & @LF)

If IsArray($module) Then
    MsgBox(0, "Success", "Success!")
Else
    MsgBox(0, "Failed", "Failed!")
EndIf

This is sensible because Autoit will support empty arrays with the next version.
