WinWaitActive and @error

[shaggy]

From helpfile:

Function Reference

WinWaitActive ( "title", ["text"], [timeout] )

Return Value

Success: Returns 1.

Failure: Returns 0 if timeout occurred.

but it doesn't work!

I need to trace windows with changing header. For example, Windows Explorer and ACDSee header may be "test" or "C:\test" on difference computers. It depends on program option, that users can change. (Its easy with RegExp, but i didn't found it in AutoIt3). So i start explorer c:\test and use WinWaitActive("C:\test", "", 10) before other actions. BUT, in case of WinWaitActive timeout, i need to check for windows with name "test", that is Explorer, too. And i can't do it, because i always get @error = 0.

You can check it with this script (folder C:\test needs to be created):

Run("explorer.exe /e,c:\test")
WinWaitActive("C:\test", "", 10)
If @error = 0 Then
   MsgBox(0, "1:exit with", @error)
Else
   MsgBox(0, "2:exit with", @error)
EndIf

Run this script, then in WinWaitActive change C:\test on any not existing folder. In both cases you'll see: 1:exit with 0

I only may be wrong, if return value is not placed in @error. But where?

Opt("WinTitleMatchMode",2)
Run("explorer.exe /e,c:\test")
$ret = WinWaitActive("test", "", 10)
If $ret = 0 Then
   MsgBox(0, "1:exit with", $ret)
Else
   MsgBox(0, "2:exit with", $ret)
EndIf

Use Gary's code for this need.

It will match a substring within a title as you requested.

As for RegExp, see this post:

As for the "bug" - try this code:

Run("explorer.exe /e,c:\test")
$var = WinWaitActive("C:\test", "", 10)
If $var = 1 Then
    MsgBox(0, "Success: Returns 1. ", $var)
Else
    MsgBox(0, "Failure: Returns 0 if timeout occurred. ", $var)
EndIf
