Reference to a non-shared member requires an object reference

[johmolan]

I have a Form called Form1 where I use Database45DataSet....

When I run the command Database4DataSet1.Clear() in Form1 there is no problem. When I try to run the same command in Form3 I get the errormessage in topic.

Reference to a non-shared member requires an object reference

I have tried to import tje dataset and the project application but no luck,
How can I solve this problem?
