Once you have passed enougth exams to become an MCAD, MCSE, MCSA etc. do you get a physical certificate in the mail or are you supposed to just use the online transcript?

Good idea but not the answer. I checked the form properties and the CausesValidation was indeed true for the form. But even with it set to False I still get the same problem. its a frustrating little problem.

I've been reading up on how to use validation on forms. I need to validate a field has been filled in so I have used the 'Validating' event that is called just before my form textbox loses focus. If the field is blank, the focus stays on the textbox and an appropriate error message is...

Thanks dude.

many thanks.

I am trying to make sense of the new VB.Net suite after using VB6 for some time. I have just tried an example from a Wrox book that works fine but I can’t quite understand. The example is shown below. What I don’t understand is the line:- objSubFolders = New...

Is there a definitive Network+ source of information? I have referenced three sources and ended up with two different methodologies for trouble shooting a network problem. Transcender says:- Identify Problem Recreate Problem Define Probable Cause Define Correction Plan Implement Correction...

We have a small network and I am looking into increasing performance. One possibility is using a switch. I just need to make sure my understanding of a switch is accurate. Does a switch merely service the segment it is connected too? In other words, does it improve performance by increasing...
