Interrupt a stalled Page Load to do a Refresh on IE Page.

MGuyM · Post by **MGuyM** » Wed Jul 16, 2008 8:04 pm

I've run into a bit of a problem with a Script that I'm running. I have the following code to load a web page:

LibFunc>hIE,Navigate,r,%IE[0]%,http://www.microsoft.com
LibFunc>hIE,WaitIE,r,%IE[0]%

The problem I am running into is that the second line is waiting for the page to load completely before it continues. What I would like to do is to do a "Refresh" of the page if it doesn't load in XX amount of time (say 5 seconds).

I haven't been able to figure out a way to do this and I recall reading that the IEAUTO.DLL has a Refresh Function and was wondering if it might be possible to get a small enhancement to the "WAITIE" Function in that if the page doesn't load in XX seconds (which might be another option on the WAITIE Line), that it would automatically do a REFRESH Function and continue to wait.

In my particular application, the Refresh is all that is needed as I can watch my script run and when I see it stalled waiting for the page to load, I just hit the Refresh Button on the Toolbar and then my script continues.

I would appreciate anyones help on how I might be able to program around this and maybe Marcus could put an update in the WebRecorder WaitIE function to automatically do a Refresh???

Thanks!

You might try:

[code]
Let>WW_TIMEOUT=5
LibFunc>hIE,Navigate,r,%IE[0]%,http://www.microsoft.com
Label>TryAgain
WaitWindowOpen>Microsoft Corporation - Windows Internet Explorer
// WWO Times out after 5 secs. If it Times out, check WW_RESULT.
// If set to FALSE, refresh page.

If>WW_RESULT=FALSE
GoSub>RefreshSEDI
Goto>TryAgain
Endif
// Continue normally

SRT>RefreshSEDI
Label>RedoF5
//Press F5 to refresh page
Wait>1
Press F5
Wait>0.3
// Wait for Refresh Warning Window:
WaitWindowOpen>Windows Internet Explorer
Wait>0.2
If>WW_RESULT=FALSE,RedoF5
Label>RefreshAgain
SetFocus>Windows Internet Explorer
// Try long Wait before hit Enter
Wait>2
// Retry to refresh
Press Enter
// May take long time to refresh page; Wait 2 secs
Wait>2
IfWindowOpen>Windows Internet Explorer,RefreshAgain
End>RefreshSEDI
[/code]

The problem that I see with what you suggest is that your assuming that the Window Title Bar will say "Microsoft Corporation". I just used Microsoft as my sample site. The Page I am trying to view is actually dynamic and changes each time you hit the F5 Key and I continue to reload the page to get different information and then I'm extracting the information from the page.

Thanks for the suggestion.

I could be wrong but in my experience "Windows Internet Explorer" is part of every Internet Explorer window name. So it seems to me you could use "Windows Internet Explorer*" (be sure to include the asterisk) as the name of the window in all of the WaitwindowOpen> lines. As long as you only have one instance of Internet Explorer running WaitwindowOpen> should work properly.

That's generally a good assumption but it is possible (via the registry) to change the IE default title, some companies do it to customize the browser, see my demo:

Hmmmm.

Then use the window's handle, that shouldn't change.

A timeout for WaitIE is on the wish list. In the mean time my preferred solution would be to use image recognition. Use WaitScreenImage with a timeout. Use it to wait for a part of the resulting page.

Thank You Marcus for putting this on the Wish List.

The Page is dynamically changing, so it's difficult to program an Image Recognition to it since what I might program today, could be gone tomorrow.

Thank You Again!

You could use WaitScreenImage to wait for "Done" to appear in the status bar. With a timeout. That is constant.

Will that even apply if I'm hiding IE?

Post by **Marcus Tettmar** » Thu Jul 31, 2008 4:48 pm

No, won't work if IE is hidden. WaitScreenImage can only see what is visible.

When IE is hidden, does MS still wait for the Pages to load completely? I guess with IE hidden, the Timeout feature becomes more beneficial

Thanks!

Yes. All the IEAuto.DLL functions work the same whether IE is hidden or not.

With that in mind, I'm really wanting this feature added as soon as possible

Thanks!

Hi MGuyM,

I'd suggest adding a Poll here to your message to drum up support however, since its already on the Wish List and since this enhancement (to IEAuto.DLL) makes so much sense, I have a feeling Marcus doesn't need any convincing.

Sidenote: The HTTPRequest> command is already covered... here's a Help file out-take:

By default there is no timeout for the HTTPRequest command and requests will wait indefinitely if the server fails to respond. To change this set the HTTP_TIMEOUT value to the number of seconds to wait.

Thanks for posting this MGuyM and thanks Marcus for the never-ending improvements...
