Hi,
provide a KeyDown handler that checks the current content of the TB plus the new key,
and when not acceptable, set both e.Handled and e.SuppressKeyPress true.
if you decide to support text paste (CTRL/V), you must check for that too (you may opt
to do that in the TextChanged handler).

I call the forms by these codes .
Dim frmsp As New Form1 ' may splash form with graphical objects
frmsp.MdiParent = Me
frmsp.Show()
Dim frmUser As New FrmUserInfo ' my form that its loading takes several seconds
frmUser.MdiParent = Me
frmUser.Show()
frmsp.Close() 'after showing the form I close the splash .

but why do you have to Parentme a Form. remove the Statemet in Both the Splash and the user form. you dont need that.A Splsh should not have a arent, it should appear for few seconds and disappear, i suggest you use timer control for it, after its done, mybe you can choose to display an MDI form ythat will be the parent of the forms,but remember that the Splash is out of memory, and dont lie to your selff thinking that if you have written .close method you have dispose it. and try running it again

Read through the registry and it should show you everything that is installed. How to do this in code is left as a programming exercise

hi
I understand your problem, n\but still even that exe reside in that machine you call a server it will be like the users are accessing from their machines, so what you need is a different Solution, you want your users to access your Application from the central point, then its fine. it can be done in exe(windows)but now you have to install the exe to every user, but there is an easy way, "WEB", you can create what you have created in Windows and di it to Web, and you will be sure that its been accessed centrally. look at my articles on N-tier, you can Convert them to Web and Create a Solution that you want.
Sorrry for answering you so late , am Sick
Hope this helps

hi vijaylumar
Am sorry to answer you so late. am very sick. but lets get back to your questions. The N-tier and 3 Tier is the same thing. but "N" means that you can use any number . that means 3 is the number of layers you have in your Application, so when we say N-tier,we include all types of designs that has 2 or more layers. and the way you read it from my article its correct,presentation layer , bussiness layer , data layer. in the N-tier you can have as many tiers as you want, but remember the reason we use N-Tier is to make the application code maintanable and be able to practise polynorphism.
To solve your problem, design the your solution exactly as my last Article part 2. if you need more answers reach me on skype "vuyiswamb"
hope i helped

I thing that the problem you are experincing is due to .NET Framework Security rights for the zone that you are trying to run from. Local servers (as apposed to Internet servers) usually reside in the Intranet zone.
You can adjust the each Zones security in the .Net configration, which is in Control Panel.
Also you will have to Strong Name your assemblies etc.
