Listbox.listcount property - application defined or object defined error

Hi,

I am struggling with a really weird and annoying error. I have this line of code in a macro:

Please Login or Register  to view this content.

This line is throwing the run time error 57121 - Application defined or object defined error.

Here is the weird/annoying part - Only certain computers are giving this error. This code works absolutely fine on my laptop but is giving the run time error on a colleague's computer.

"UtilSelectServiceListBox" is an activex listbox control. I have to know the number of items in this listbox for the program to work further so I am open to any/all suggestions that will fix this issue. It is extremely annoying that this is an issue on only certain machines. I also searched for alternatives to the "ListCount" property and couldn't find any that solved my issue.

Hi,

Since this is occurring on selected computers, the problem is probably due to a Microsoft update from December 14th, 2014 that affects 'Active X'.

The following URL has a 'fixit' link that may solve the problem. https://support.microsoft.com/kb/3025036
