IE.au3: 'Object referenced outside a "With" statement' when searching for frame and site is down

[mistermassacre 0]

The script:

#include <IE.au3>

_IEErrorHandlerRegister()

$oIE = _IEAttach("http://www.google.com", "URL")

$oFrame = _IEFrameGetObjByName($oIE, "frame_that_doesnt_exist")

MsgBox("","",@error)

If I have an explorer window open to the google front page and I run this script then I can see the @error being set to 7 (no frames found) which is just as expected.

However if I block google so the page wont load (for example if I setup IE6 to use a nonexistent proxy server), refresh explorer (getting

The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings page) and run the script it generates the following:

I am completely mystified as to why this script generates a fatal error when trying to find a frame on a web page if that page is unavailable, am I missing something?

I've tried the same thing using _IEGetFrameCollection($oIE, 1) instead of _IEFrameGetObjByName($oIE, "frame_that_doesnt_exist") and I get the proper @error code, the problem seems exclusive to _IEFrameGetObjByName.

Ah, you caught me making a mistake I correct here in the forum all of the time...

Line 800 is currently

If $oFrame.name = $s_Name Then Return SetError($_IEStatus_Success, 0, $oTemp.frames($s_Name))

and needs to be

If String($oFrame.name) = $s_Name Then Return SetError($_IEStatus_Success, 0, $oTemp.frames($s_Name))

You can update your copy if you like for now and I'll get the fix in the pipeline.
