GDI+ Animation start/stop issue

5 posts in this topic

Hello All,

I modified one of UEZ's loading animations to start and stop when requested.  Problem is, in my main script it stops executing after starting the animation, yet when I tried it in a simple notepad test script it works fine....

This code works fine....

#include <_LoadingAnimation.au3>
BlockInput(1)

    _StartLoadingAnimation()                 ;<--------  Animation Start
    Run("notepad.exe")

    WinWaitActive("Untitled - Notepad")
    Sleep(2000)
    _StopLoadingAnimation()                  ;<-------- Animation Stop

    Send("This is some text." & @CRLF & '"This is on a new line!"')

    WinClose("Untitled - Notepad")

    WinWaitActive("Notepad", "&Save")

    send("!n")

BlockInput(0)

....while this block of code starts the animation (_StartLoadingAnimation) but never reaches the MsgBox.

;Handles the saved BATCH index screen
WinWaitActive("[CLASS:#32770]", "The following index is saved")
ControlClick("[CLASS:#32770]", "The following index is saved", "[CLASS:Button; INSTANCE:1]")

;Could use progress display here
_StartLoadingAnimation()               ;<-------- Animation Start

MsgBox(0,"Test", "Right after animation starts")
;Clicks the save button on the layout screen just prior to DBF creation
WinWaitActive("BCC Mail Manager FS Network - ADMIN", "")
WinWait($listName, "")
Sleep($mediumDelay)
_StopLoadingAnimation()                ;<-------- Animation Start
WinActivate($listName, "")
;MsgBox(0,"Test","Before Click")
ControlClick($listName, "No Records", "[CLASS:TPanel; INSTANCE:2]", "left", 1, 45, 10)

I'm about to leave work for the day, just thought I'd post and see if I'm missing something obvious.  I know I'm not giving a lot of code, but I just can't see a reason why it would work in my notepad example and not the main script.

In the "not working" example, the WinWaitActive and WinWait statements refer to windows that do exist and ARE appearing/activating but the statements do not react as normal.

Thanks in advance for any input!

The interesting part here is the _StartLoadingAnimation() function.

Can you post it?

I'm sorry, I was in a rush to get out of work....  It didn't occur to me until later how useless this post would be without the #include code.

Below is the code...  hopefully I didn't butcher your work too badly.   :)

....while this block of code starts the animation (_StartLoadingAnimation) but never reaches the MsgBox.

 

That's not true ;)

The animation has the topmost style set and the MsgBox is behind the animation.

You have to set either the MsgBox also topmost or set it as a child of the GUI.

Here both together:

...
_StartLoadingAnimation()
MsgBox(262144,"Test", "Right after animation starts", 0, $hGUI)
...

That's interesting.  It never occurred to me that the MsgBox would be behind the animation but it makes perfect sense.

I tested the MsgBox code you posted and, sure enough, it popped up just fine...  so the code is executing after _StartLoadingAnimation()

However, I added the MsgBox as part of debugging.  The original issue was that without the MsgBox it seemed like _StopLoadingAnimation() never gets called after the WinWaitActive, WinWait, and Sleep statements.

Thanks to you I at least knew for sure that script execution was continuing after _StartLoadingAnimation()... so moving down the script I tested my WinWaitActive statement.  Turns out the loading animation was changing the way in which focus was being transferred.

I reconsidered my code logic and realized that my WinWaitActive statement was unnecessary anyway.  Removing it made the animation start and stop as expected and made that section a little more reliable overall.

Thanks again UEZ, marking this one solved!
