Hey,
I want to detect the position of the blinking cursor (sorry, I'm drawing a blank on the name of it). You know, the cursor in front of what you are typing? Anyway, is there a way I can do that?
And also, is there a way to convert all text in a Rich Text Box to Rot-13? The code I'm using won't convert the text. See below:
<br />
Dim AllText As String<br />
AllText = RichTextBox.Text<br />
Dim Part As Integer<br />
Part = AllText.IndexOf("a")<br />
Dim FileName As String<br />
FileName = AllText.Replace(Part, "Z")<br />
Dim Part2 As Integer<br />
Part = AllText.LastIndexOf("b")<br />
FileName = AllText.Replace(Part2, "Y")<br />
Any help would be appreciated! Thank you! 
P.S. I do not name my controls Generic names like "RichTextBox", I was only using that as an example!

Please look at my reply to your earlier post for Rot-13...
To detect the current position of the blinking cursor, I think there is a property SelStart that you can use.

How to format DateType form MM/dd/yyyy to dd/MM/yyyy of an Application,Which Writed by VB.net

Changing the Windows system settings is NOT a good idea. If your app does that on my machine, I'll uninstall your app faster than you can blink an eye.
If you want to show a DateTime in a certain format, all you have to do is give the format string to the ToString() method or you DateTime:
Dim dt As DateTime = DateTime.Now()
Console.WriteLine("Current Date: " & dt.ToString("dd/MM/yyyy"))

You're question and code sample are very confusing and don't lend themselves to an clear explaination of what you're doing. THe best I can tell you without a better description of the problem is:
Dim myForm As New Form1
myForm.Show()

Do you mean that you just know the name of the form and you would like to display it?
You can try to look in the Forms collection to match the name and display that form, using the Show method.
Hope this helps

If all you have is the simple form name as a string, then you need to use some sort of Reflection to create an instance of that type, AND you have to use the full name of the type, which is "Namespace.Type".
Here's one approach:
"Loading Classes on the Fly"
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnadvnet/html/vbnet10082002.asp
Here's a similar way, that does not use a configuration file. I just used the assembly name, which should work, unless you or another developer has placed the forms in a different namespace.
Either way, you have to know the namespace of the type. If it happens to be the same as the assembly, which usually it will be, then you're in good shape. If not, you just have to know the namespace, and prepend it to the form name. (And don't forget to use proper exception handling. Do as I say, not as I do.)
Imports System.Reflection
Module Module1
Friend Function GetFormUsingGetType(ByVal formName As String) As Form
Dim myAssembly As [Assembly] = [Assembly].GetExecutingAssembly
Dim myForm As Form
Dim myFormName As String
Dim myType As Type
Dim myAssemblyNameObj As AssemblyName = myAssembly.GetExecutingAssembly.GetName
Dim myAssemblyName As String
myAssemblyName = myAssemblyNameObj.Name
myType = myAssembly.GetType(myAssemblyName & "." & formName, True, True)
myFormName = myType.FullName
myForm = CType(myAssembly.CreateInstance(myFormName), Form)
Return myForm
End Function
Friend Function GetFormUsingActivator(ByVal formName As String) As Form
Dim myForm As Form
Dim myFormName As String
Dim myAssemblyNameObj As AssemblyName = [Assembly].GetExecutingAssembly.GetName
Dim myAssemblyName As String
Dim obj As System.Runtime.Remoting.ObjectHandle
myAssemblyName = myAssemblyNameObj.Name
myFormName = myAssemblyName & "." & formName
obj = Activator.CreateInstance(myAssemblyName, myFormName)
myForm = CType(obj.Unwrap, Form)
Return myForm
End Function
End Module

I am creating a network instant messaging program in VS 2005. I want it to work in much the same way as msn Messenger, as in a realtime chat where multiple people can input messages to one single chat box that is shown on each pc. I am unsure how to go about sending and recieving messages and was wondering if anyone could point me in the right direction.

I was working on a similar problem only a week ago!  What a coincidence!
Anyway, if you have a network drive set up (a drive on a computer that all computers in your house can access), create a text file. Then when somebody submits some text, just take that text and add it to the main file. From there, just show the contents of that main file in another text box. Simple, and a lot easier than learning networking!
I hope you can figure it out. Let me know if you need more help!

Network chat is one of those ubiquitous apps that every newbie wants to make. All you have to do is type "vb.net chat[^]" into Google and you'll come up with about 4,000,000 hits, most of which have code examples of what you want to do.

Trust me, it works great! And a lot easier than networking!
Just try it!

And totlay useless if the two people who are chatting are not part of the same network, like say, on the Internet!
You were wondering why nobody was downloading the stuff from your site? This could be a clue...

For my application i need to create arrays on runtime.
How will i do that?
Or do i have to make something like a method which creates an array while developing and make an instance of it at runtime to rename it finally?
Thanks

I don't understand what this means.
To be honest, I don't understand your question. do you want to assign an array, or create a variable that wasn't in your code before ?

Just create a method that creates your Array and call that method at runtime! Or, just put the code that creates the array in the "Form.Load" procedure.
Or do you want to know how to create an array?

Like Christian, I can't figure out what you really want to do. You're post sounds a bit confused.
Are you looking for something like this?
Dim myArray() As String
creates an array of Strings.
You might want to explain what your trying to do in more detail and include a code snippet showing where you want this array to show up.

Ok, maybee a wrong start of this discussion.
Let's try it again.
I am writting an application (kind of callcenter server), which controls the traffic from a telephone system (PABX).
The application let me insert callcenter agents(name and number), extentions(name and number) and callcenter groups(name and number).
When i insert a callcenter group an array has to be created with the callcenter group number as it's name. finally i can add agents to the group array.
So, for example:
Two agenst were inserted:
200 Bill
201 Albert
Then two extentions were made:
100 extention 100
101 extention 101
Finally one group is made:
400 Sales
After creating the group, an array has to be created with 400 as it's name.
The agents have to be added to the group array.
So, i know how to make an array: Dim groupArray() as Integer.
And i know how to add agents to the array.
But during runtime there have to be an array created everytime when a group is made and the array name has to be the number of the groep.
Thanks
regards

I think what you probably need is a dynamic array of collections, so you can add a collection every time a new group is created.
Hope this helps
