• Windows Forms Any shortcut to passing a form as an argument?

  Any shortcut to passing a form as an argument I was hoping that vs 2005 would ease the problem of passing a form as an argument over vs 2003.  Looks like not.  It is very cumbersome to overload a procedure for each form, so much so that there's no reason to do it. sub XXX(frm as New Form1) Sub XXX(frm as New Form2)   etc. It's easier to repeat the code within the form.  Is there a workaround dennist ...Show All

• .NET Development Identity from Access

  Hi, I have been searching around for a solution to this problem with not much luck. From what I have read, I don't like the answer, but I thought I would check just in case.

I have been purely using the dataset designer and using the tableadpater methods I have created in the designer as I am still getting to grips with the w ...Show All
