As I said when you posted this last time, you get "System.__ComObject" because the object does not implement ToString. The default implementation returns the class name.

You need to cast it to a normal datatype before using it.

Please, don't just delete questions because you don't like the answers, it is rude!

No, the object doesn't implement ToString.
When you declare a class, it inherits properties and methods from the base class: one of these is the ToString method which by default returns the name of the class. If your class does not implement a more specific ToString that returns the value of the data within your class then the default one is used, and you just get the name - as you have seen. You need to convert whatever
GetRecord(0)(0)
is returning into a type that VB understands directly before you can use class specific methods.
I can't tell you what to do wioth it, and I have not idea what type it returns! (other than __ComObject) It could be a Date, a specific structure, anything. You need to look at your code and work out what it should be! :laugh:

Solution 2

To fix the issue, you need to use .Value, like this:
Rows.Fields(0).Value.ToString
