How to use a self compiled VB6 dll with AutoIt

[mozart90]

Hi,

This is a small Tutorial of how to build a DLL in VB and use it in Autoit.

Some time ago I was searching how to integreate a small VB6 Function as dll in Autoit.

The problem was: Nobody could tell me how to do.

Now, here is the answer

First of all you need Visual Basic. (I tried this with V6)

1.) In VB open a new Project. Select ActiveX Dll.

2.) Rename the 'Class1' in let's say: 'Myclass'

3.) Insert the desired Code: For Example

'---------------------------------------------------------------------------
' VB Code
'---------------------------------------------------------------------------
'In this examle an perhaps an Api delaration which is called in the following function 

 Private Declare Function GetWindowsDirectory Lib "KERNEL32" _
      Alias "GetWindowsDirectoryA" (ByVal lpBuffer As String, _
      ByVal nSize As Long) As Long

' Actually the function itself - Just output the Windows Dir 
   
Public Function WinDir() As String
      Dim sDirBuf As String * 255
      StrLen = GetWindowsDirectory(sDirBuf, 255)  ' Call the api function 
      WinDir = Left$(sDirBuf, StrLen)  ' that's what is returned 
End Function

4.) Then deside for a Projectname. Goto Project - Properties in VB and enter a Projectname. Lets say 'mydll'

(This is the proposed Filename for the dll too)

5.) Compile the Project. You have finished in VB

6.) Register you new dll with 'regsvr32.exe mydll.dll'

7.) Use the dll in Autoit as following:

;---------------------------------------------------------------------------
; Autoit Code; needs beta I think  
;---------------------------------------------------------------------------

$obj= objcreate("mydll.myclass");create the object 
$ret= $obj.WinDir ;call the function
msgbox (0,"From Call",$ret) ' show the guy

Thats all. I know there is an easier way to get the system directory - but it's just an example

So have fun with a closer interaction of VB and Autoit.

Pretty cool...here is also an example of creating VB6 ActiveX control and using it in AutoIt.

See this and I also added another function "Caption" which changes the text.

Attached is .ocx file and autoit script (you must run 'regsvr32.exe animation.ocx' to use)

Here is a VB Button that you can change the color of.

Does anyone know how to get events (clicks) from this button?

(you must run 'regsvr32.exe VBButton.ocx' to use)

('regsvr32.exe /u VBButton.ocx' unregisters the control)

In this example, how do I modify the activex control's properties using AutoIt script (like: 'Visible', 'ToolTipText', etc.)?
