wb := ComObjCreate("InternetExplorer.Application") - How to close after use
I have a script which uses the code below to create an Internet Explorer object. After the script has executed, the IE objects are still hanging around. What is the correct way to dispose of them within the script?
Thanks.

For some reason, neither of these works. The first one throws an error.boiler wrote: ↑27 May 2022, 04:52Code: Select all
wb.Quit()
This should also work:Code: Select all
wb := ""

The second one executes but it leaves the IE executable running. If I do
Code: Select all
wb := ""Code: Select all
wb.Quit()I can't think that statements like the one below would hold a handle to the IE instance and prevent it being destroyed would they?

wb.Quit() can’t do anything at that point because wb is no longer containing the web browser object.flipside555 wrote: ↑ The second one executes but it leaves the IE executable running. If I dobeforeCode: Select all

I don’t know what’s happening to cause your issue. It might be that you’ve assigned something else to wb in the lines of your script that aren’t shown, so wb may no longer be an object that supports the .Quit() method. You might want to check the rest of your script to see if you assign anything else to wb after the initial wb := ComObjCreate("InternetExplorer.Application") including any elements of the main web object. The variable wb cannot be assigned anything else.flipside555 wrote: ↑ I can't think that statements like the one below would hold a handle to the IE instance and prevent it being destroyed would they?

This seems to be the line causing the problem. Calling wb.quit() before this line is successful. Calling it after fails with the error message. I have to confess I don't really understand what is going on in this line. I wrote the script a few years ago, and I must have copied this part of the code from this site.boiler wrote: ↑06 Jun 2022, 07:33I don’t know what’s happening to cause your issue.

This is a minimal case.
Code: Select all
wb := ComObjCreate("InternetExplorer.Application")
wb.Navigate( "https://www.microsoft.com/")
;wb.Quit() here works

You have assigned the variable WB to be the variable associated with that ActiveX control (that's what vWB does). You shouldn't tie it to that variable. Change the vWB to something else like vWeb.

Re: wb := ComObjCreate("InternetExplorer.Application") - How to close after use
Yes, thanks. That's what I did. I am manually building an HTML page that I want to display. I didn't fully understand that line and ended up re-using the same variable I'd used earlier when I created the com object. I renamed it vWX and it's working now. Thanks a lot for your help.
