Waiting for a document to be fully loaded

7 posts in this topic

I have a general question about approach to solve a particular problem - I am using AutoIt to do some validation of applications on virtual machines, and it is working really well. I have a particular issue that I am running into and am hoping to see if anyone has thoughts on the right approach to solve this.

I have cases (the example I'll give here is with Powerpoint) - I have a script that starts Powerpoint, and then loads a very large document. I want to validate that the whole document is loaded and that the document contains a particular string at the end. I also want to be able to detect that the search for the string was successfully found.

The way that I am validating that the application is working properly, and that the document is loaded correctly, is the following:

- Start powerpoint

- Use WinWaitActive to wait for the application

- send alt-f, o to bring up the open dialog

- send the filename desired and alt-o to open

- send ctrl-f to find

- send the text on the last slide of the powerpoint

- (this is how I validate if it found the text - I send {ESC}, then check to see if the "Find" window is still present - if the text is found, it just highlights it, and when the ESC is sent, the find window is closed. If the text isn't found, it generates a dialog window, and the ESC dismisses that, but the "Find" window is still there. By checking for presence or absence of the "Find" window, I can determine if the text was found.)

Now, this works great for smaller documents - everything runs quickly, and I clearly get the correct status from the validation sequence I describe. For the large document, though, I have a general issue - the find is fired before the document is completely loaded - so it doesn't find it in the part of the document that is loaded. I could solve this by putting a reasonable sleep before I try the find, but I am not only using the script to validate that the find worked, but also to get a general measure of performance, how quickly the document loads. If I add a sleep to solve the find problem, I will negate the ability to get measurements of how quickly the document loads.

I am open to other suggestions on how to validate that the document completely and properly loaded - or if anyone has suggestions on how to accomplish what I describe above.

Thanks in advance for any ideas/suggestions!

COM would probably be the best way to tackle this... it is a deep subject, but there is an example of opening a presentation that should not return control to your script until the file is fully open. There are many ways in COM to do the other checks you are trying to make. Google: PowerPoint Object Model MSDN

$oPPT = ObjCreate("Powerpoint.Application")
$oPPT.visible = True
$oPPT.Presentations.Open("C:\IntroducingPowerPoint2007.pptx")

Ah, good suggestion. I hadn't been thinking about it at that level, that makes sense. I will give that a shot and see how it works for me. That certainly gives me more flexibility.

Thanks!

Thanks, a good suggestion and may work for me in some of the other applications that I need to test - I don't think it will handle the powerpoint case though - it seems that it does the loading in the background and keeps the mouse pointer a regular pointer in the process. I know that some of the other apps leave the hourglass while it is loading, so it will work for those.

Thanks!

Be sure to place a sleep or GUIGetMsg() in a while/wend loop to stop CPU consumption.
