The thing is that after the concatenation operator ## the macros don't get exp ...Show All

• Windows Forms Specify ConnectString at Installation Time

  I want to write a C# program which needs talk to an Access database. I plan to add this program to Windows Task Schedule so the program can run periodically and automatically.

That is to say, I do not know the ConnectString until installation time. How can I solv ...Show All

But the problem is that the styling shows that an item is selected. Best regards,   Thomas S. Andersen   BTW, as a workaround I'm using this at the moment: ListView1.SelectionChanged += delegate ( obj ...Show All
