Window Handle to String - String To Back To Handle - (Moved)

[AutoitMike]

I have searched this forum on this subject and I cant find a difinitive answere on how to do this. Many answeres are “There is no reason to need this”.

Heres my reason:

I am working to automate operations on an application where I need to select a specific instance of an app where multiple windows exist that have the same title. There is no text in the windows that define the proper window to activate. 

I can store the window handle in a field in a database that this app uses (SQLite) when I open each instance. I then can get the handle at a later time when I need to find a specific window (Using WinActivate(“[Handle:” & $MyHandle]”,””). However, I need to be able to store the handle as a string because the SQL Select function (Using AutoIt) returns only strings and even though the fields are VARChar I dont believe that they can store objects anyway.

Once any instance is opened, I can count on the window to not be closed until it is no longer needed, thus, the handle stored will be valid.

 

OR

 

Is there a better solution?

Thanks

OK,

I found out the following:

You can see a window handle (EG msgbox), you can store it outside of AutoIt. (EG file)

But when you get it back, you need to use the function Ptr to make it a window handle.

Example;

$C1='0x0242137A' ;I know that this is the actual handle of the window I want
$C1=Ptr($C1)
WinActivate($C1) ;This works

Isn't the example of the HWnd function in the helpfile exactly what you are looking for ?

[AutoitMike]

Yes, I saw that after discovering Ptr().

I didnt research it at that time.

I am going to investigate HWnd.

For now, what works, works.

 

Thanks much for the input.
