• SQL Server DISTINCT COUNT - unhelpful error message

  Hi, I need to return a distinct count of customers who have ordered goods. To do this I created a measure of type DISTINCT COUNT, over the CustomerID field in the orders fact table.

The measue is created in a new measure group OK, and the cube processes through OK. However when I come to view the data b ...Show All

• Visual Basic vb6 to .Net conversion issue

  I have a large application build up of smaller projects. I have several modules shared among these projects. I also have forms shared among modules and projects. In VB6 I could compile a project even if I had a reference in a function that's part of a project's modules to a form which isn't included in my project, but I have no reference to this function in current project. Now as I've seen, in VB.Net this cannot happen any more. So, what is the ...Show All
