If your subject is the same as your text, the subject is way too long, or the text way too short. Or both, as in this case.
Don't write everything using bold.
You have to be more specific for anyone to be able to help you. What do you mean by "posting" characters in a textbox? What is it that is special about the characters? Why the limitation of two characters?
As you state that you want to use VB.NET, why didn't you post the question in the VB.NET message board instead?

I am not sure what the special characters are. Maybe you could use a MaskedTextBox or a MaskedTextProvider.
For a simple fix you could handle the key press event. In my app I just wanted post code data so I limited the MaxLength property of the post code text box and handled the key press event not allowing any chars others then numeric chars to be entered.
<br />
Private Sub PostCodeTextBox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles PostCodeTextBox.KeyPress<br />
If System.Char.IsControl(e.KeyChar) Then<br />
Exit Sub<br />
End If<br />
<br />
Dim validChars As String = "0123456789"<br />
<br />
Dim ch As Char<br />
ch = e.KeyChar<br />
<br />
If validChars.LastIndexOf(ch) = -1 Then<br />
e.Handled = True<br />
End If<br />

Hello All,
I am using .NET Framework 1.1. I am working on a web application. I have a 3rd party dll used in that. Now my project is running fine on my local machine. But when I setup it on the server it gives CS1704 error (An assembly with the same simple name 'SomeName' has already been imported. Try removing one of the references or sign them to enable side-by-side.)
Now I have only one reference to that assembly in my project.
Any suggestion ??
Thanx in advance

I was wondering whether anyone knew how to go aobut getting a list of all of the keys on the keyboard, like in programs which have comboboxes which allow you to select the keys you're going to use for your shortcut.
I'd appreciate any help you can offer. preferably in j# but anything else is still appreciated
Thanx

Has anyone used the CSLA framework as is? What has been your experience with it? I am trying to figure out whether to create my own framework, which would consist of a subset of the features in CSLA, but not the whole thing (namely remoting) or use it as and extend some functionality to it.
If anyone could provide feedback on their experiences of CSLA.Net I would grately appreciate it.
Thanks in advance.

Hi,
With .NET 3.0 and Vista, i hear that MS is giving us an almost completely Managed API sub-system of Windows OS (maybe on top of or side by side along with the Win 32 sub-system). Is this correct? I could not find any specific mention about thin anywhere in MS site.
Also is it true that .NET 3.0 will only support Win XP SP2 and Win 2003 and above (i.e. Vista, etc) and not Win 98/NT/Win 2K. If that is true (i hope not) then how do we deploy .NET 3.0 apps for Win 98 through Win 2000 users?
Thanks.

Not true. .NET 3 is not a replacement for Win32. .NET 3 is .NET 2 with entensions added. These are Windows Presentation Foundation (WPF), Windows Workflow Foundation (WF), Windows Communication Foundation (WCF), and Windows CardSpace.

True, unless the requirements change at the final release, but I doubt they will.

You don't since those O/S' are not supported. You'll have to use .NET 2 are lower depending on what you're targeting.

I knew this naming decision would cause problems. When it was still called WinFX it was something distinct and didn't cause people to think they needed to upgrade. Not that you need to upgrade from .NET 1.1 to 2.0 if it's working, since you can install the runtimes side-by-side. You can still install .NET 1.1 on Windows Vista Beta 2.

The problems have just begun. Think of how confusing it will be for "decision makers" at companies when they need to decide if they want to use .NET 3 or 2. Well, 3 is 2, but 2 is not 3. Hmm...

:-DDear All,
Did .NET Framework Designers used Design Patterns for their Base Class Libraries? If yes, How? And what are those patterns and especially
in which BCLs?(Mainly my interest is in C#). What are the Top 10 Design patterns used in top 50 BCL(.NET) out of 23 GOF patterns??

Of course!
Raihan Masud wrote: If yes, How?
Various patterns are used throughout the entire BCL.
Raihan Masud wrote: And what are those patterns
These are questions that you'll have to ask the Design Team. I'm willing to bet that it's more than just a few different patterns in a few different places.

hey folks,
what is the fastest way to have a clean fresh System.IO.MemoryStream each time i write into it?
one way is to make a
ms.SetLength(0)
before i write in to it. Another way is to create a new one each time. i think this two methods aren't very fast. is there another posibility to clear a stream?
thanks, bernd

|

|

No, there isn't. If you want something faster, perhaps you should use something other than MemoryStream. Why the need for speed?
---
b { font-weight: normal; }
|
|
|
|
|
thanks guffa,
speed is always nice to have  and what's faster, setting the length to 0 or create a new one?
|
|
|
|
|
That depends. Setting the length to 0 should probably be faster than creating a new one, but the speed of that single action is not all that affects the speed of your application. A MemoryStream that is reset will probably handle memory allocations differently from a newly created one. I know too little about that difference, and especially too little about what your application is doing, to advice you in either direction.
Don't do premature omtimization. You should always avoid anti-patterns (known bad solutions), but specific optimization should generally be put off until you know where and why you need it.
