@error resets?

5 posts in this topic

Hi,

I am working with autoit 3.3.6.1 (this is the version I must work with)

I have a piece of code which fails because of what seems like @error resetting. So, I have something like:

Dim $o_login = _IEGetObjById(...)

MsgBox(64,"after o_login IEGetObjById", StringFormat("error level is: %d", @error)) ; error level is 4 (WTF? it doesn't even ;show in the documentation or ie.au3

AssertErrorLevel()

 

Func AssertErrorLevel()

If (@error<>0) Then ;@suddenly @error = 0. How can I make this logic work then?

...

EndIf

EndFunc

@error resets after every function returns, if the function returns with no errors then @error will be 0. You'd have to assign the value of @error to a variable and either pass that variable to the function, or make that variable global so that the function can see it.

Thanks for the help BrewManNH. Although it seems like it's with every function *invocation* rather than return, because otherwise it would not have reset it on function call. Setting it to another variable and passing that variable in the function worked! :)

I searched the net for return code 4 btw, didn't come up with something (it's not in the documentation!) Has anyone encountered that? I looked at the code at ie.au3 but until now I didn't find anything.

Thanks!

MsgBox returns @error set to zero.
