IE Errors

[felanor 0]

Hi everyone,

I am having this really wierd error. Best part, its intermittent. I was hoping someone could help me figure out why it was happening and what can be done to resolve the problem.

I am creating a program that will take a text file containing rapidshare links, click the premium button, select the first premium server, and proceed downloading the file with Download Accelerator Plus.

The program works great so far, so I cant complain. I just keep having this wierd error that crashes my AU3 script.

Below is the AutoIt console that errors and logs are displayed in.

>"C:\Program Files\AutoIt3\SciTE\AutoIt3Wrapper\AutoIt3Wrapper.exe" /run /prod /ErrorStdOut /in "C:\Documents and Settings\Administrator\Desktop\rapidshare.au3" /autoit3dir "C:\Program Files\AutoIt3" /UserParams

Below is a duplicate of the code I am working on.

Any help that can be provided would be greatly appreciated.

The code in this area is very simple (see below). The only suggestion I can offer is that in some cases, the InternetExploere.Application automation object created is in a strange state. Odd things have happened to some folks in the past when there is an iexplore.exe process on the system that is hanging for some reason. Windows, by default, manages many IE instances through a single iexplore.exe and if that process misbehaves, new browser creation has trouble as well.

The only thing I can see you can do about this would be to instantiate a user COM error handler with _IEErrorHandlerRegister(). Once the error handler is registered, the COM error will no longer cause your code to terminate, but rather will set @error and you'll have a set of global variables available that tell you more about the error (see the helpfile for more info). You can also create your own error handler in this context and handle the condition there instead of wating for the error condition to be returned to your main code stream.

If it is critical that you full automate this, see here for a technique to force the start of a new iexplore.exe instance: #396060
