Is it true to say that setting up a three tier application can be accomplished by either setting up a COM+ service as the 'business logic' middle tier or by setting up an XML web service to handle the 'business logic'?.

Thanks.

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.

I have two questions about Keyup purely out of curiosity and a bit of frustration after not being able to figure a few things out. On a Keyup event you can grab the value of the key pressed by Referring to the KeyEventArg :- MessageBox.Show("The key pressed is " & e.KeyData) The e.KeyData...

Many thanks

I have a panel on a form containing various controls. If I want to set all controls in the panel to a certain set of characteristics, I can code the following:- Dim conMyControl As Control For Each conMyControl In MyPanel.Controls conMyControl.ForeColor = Color.Blue...

Well of course I'd thought about it and I do find it difficult. With regards to your 'print' property, I think you are looking at the wrong example entirely. I am refering to pages 180 and 181. This deals with a Name property. Taking the case you describe, I would expect to see one derived...

I have come across an example in the Wrox book, 'Professional VB.Net 2003' I don't understand. It describes a way in which a property can be overloaded and overriden at the same time from a base class. This as a concept is difficult for me to grasp as overloading and overriding are to me, very...

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...

I need to search a string array for an occurance that matches a string. I thought this would be easy but the only command I could find in MSDN is the ASCAN command. Strangely VB does not recognise it. The syntax is correct but VB just doesn't seem to have it in its vocabulary. Is this the...

That did it. Thanks pal.

I have a PC with windows 2000 professional on it. On a second partition I attempted to load windows 2000 server last night. The installation failed and now I have a boot.ini style menu that starts when I boot up. The options are 'Windows 2000 Professional' and 'Windows 2000 Server'. 'Windows...

ArtieChoke Many thanks I followed your method and it works well. Rsinj I din't go with your method because I didn't feel confident enougth I understood the code. I've done lots of green screen programming, but VB is still a bit alien to me. er I do see your point though. I'm not concearned...

I have one query left. I can see how an ActiveX DLL is the best way to store the program so that its run efficiently. The only thing I am not sure about is the program flow. Consider program A will use the .DLL Active X program called MyActiveX:- I can create a .DLL exe consisting of a...
