Win32:GUI GetListContents

vollrath has asked for the wisdom of the Perl Monks concerning the following question:

When I use the following call

@items = GetListContents($child);
[download]

I get the following error message.

"Use of uninitialized value in concatenation (.) or string at testOSI.pl line 87"

testOSI.pl is my program and line 87 is the line given above that calls GetListContents. The $child variable is a valid window handle in that other calls using it return proper results.

Is it possible (a) that there is a bug in GUItest?, or (b) that the listbox control in the OSI application is not a Windows listbox (i.e., 3rd party control) and therefore incompatible with GetListContents?

If the answer is (b) incompatibility, is there an alternative scripting program/system that can read 3rd party listboxes?

BTW, the need to read the listbox is because in it is a list of possible items from which the "correct" one needs to be selected in the application. "Correct" meaning the one with the wanted key value.

Thanks in advance.

Try installing Data::Dumper and view the contents of the variables, both $child and @items. Getting a visual of what your variables actually contain can make great strides in understanding what your program is actually doing vs. what you think it's doing. I've seen that error before when looping through a list of items that contains a blank line at the end.	[reply]
