How to count freqency of letters appeared in a textbox as input?Let say we type 'I believe', thus the code should count how many each letter appears and also in percentage.
e.g. Letter 'E', Frequency = 3, percentage = 0.3 % (out of all letters)
Any code example on this? thank you~

Homework question?
How do you think the problem would be solved?
Here are some highlevel hints: Create some way to map letters to a count. Iterate through the string and add one to the relevant count for each letter you encounter. Add one also to an total counter (so you know how many letters there are in total, so you can work out the percentage) When you finish the iteration of the string, iterate through the map and output the frequency of each letter and its percentage (by the way, you need to work on that calculation as the letter 'E' occurs 37.5% of the time, not 0.3%)
If you have a problem on any particluar aspect, show us what you tried and then we can help you fix it.

I've tried using javascript, which kind of easier.I only tried out two letter which 'a' and 'b'..how can i proceed until 'z' in much easier way?
var letter, length, total, percent;
total = 0;
total1 = 0;
letter = window.prompt('Please enter a letter', '');
length = letter.length;
var my_array = letter.split("");
for(var i=0;i<length;i++){
if( my_array[i] == 'a' ){
total++;
percent = total/length * 100;
}
if (my_array[i] == 'b' ) {
total1++;
}
}
document.write('The number of \'a\'s you have input is ' + percent)
document.write( 'The number of \'b\'s you have input is ' + total1)

Given that this is the Visual Basic.NET forum, I would have expected you to be using that.
Anyway, did you think of using an array to hold the totals in? Create an array with 26 elements starting each at 0. item[0] represents A; item[1] represents B; and so on........

There is the language Property for every form. Begin with one language. Enter the test property for every control, then change the language of the form and fill the text properties for the new language. If the language is found it will be set to the windows startup language (I hope so, didn't tried it on my own, but a fellow worker did this).
Greetings,
Ingo

Well, you find it in the property-window (there I found it) when you have selected the form itself.

In the article that I posted a link to in your last post, there is a link at the top of the text of that article. Using the System Image List[^]. The code is in VB6, but is easily converted to VB.NET.

I have created a small word processing application, and I have created a new file extension (“.sln”) to save files. Like
RichTextBox1.Save (FilePath & “/myFile.sln”)
Now, I want to open myFile.sln using my word processing application when I double click Myfile.sln 
Do you know any codes to do that?
Please help me

If u want to open file with extension .sln in text box then in my opinion u need to copy the text of the file to clip board and then paste it in text box.
In this way it would appear as if file is opening directly in text box

Do you mean when you double click in windows explorer? If so this is a windows setting for the default application associated with a file extension. (eg, for most people .doc will open with MS Word).
Tip: If you Right click a file you can choose "Open with..." then simply brose for your exe. As long as your app supports executing with an argument providing the path to the file then all should be dandy (eg, c:\myapp.exe "c:\my files\myfile.sln").

Yes I mean that I know that. but it does not work. My application is already associate with .sln files. but when I double click 'myfile.sln', my application starts and loads a new document file. but it does not load 'myfile.sln'

First you have to understand what windows does (by default) when you associate a file extension with an executable program. It executes the .exe passing the file name as the first parameter like this:
C:\myFolder\MyExecutable "C:\myData\the_file_I_d_clicked.sln"
So, you need to support arguments in your executable, and if the first argument is a valid location of a file, then open it at startup instead of a blank document.
Here, I wrote a little example for you:
I had a textbox and a button, on the button I have this code:
String str = tbInput.Text;<br />
StreamWriter sr = new StreamWriter(@"C:\test.abc");<br />
sr.Write(str);<br />
sr.Close();
Then in my app start code I have this (note: string[] args are the arguments passed into the exe)
if(args.Length>0)
{
string path = args[0];
if(Path.GetExtension(path) == ".abc" && File.Exists(path))
{
StreamReader sr = new StreamReader(path);
this.tbInput.Text = sr.ReadToEnd();
sr.Close();
}
}
sorry, forgot which forum I was on...here in VB.NET
if(args.Length>0)then
string path = args[0]
if(Path.GetExtension(path) = ".abc" and File.Exists(path))then
StreamReader sr = new StreamReader(path)
this.tbInput.Text = sr.ReadToEnd()
sr.Close()
end if
end if

Thank you for your reply. I’m trying to change it according to my application..
Sorry for my delay

Hi, If you need to relate an extension type to your application, you can do it using the windows utilites, or a vb code. in windows, it's done using folder options in explorer. but in code I can help you, you should create some keys in the registry, it's very simple. you can also assign an Icon and add commands to it when you right click on a file like Edit in MyApplication or CompileFile... tell me if you need it.
but if you need that after having the type related, how to open it so:
when you double click on file, it's automatically sent to the related application as arguments. you can select multiple files and press enter so all files will be sent to you application as array of arguments.
you can catch all argument while loading application. someone tell you how using C#
but can you tell wich version of VB you use? is it vb.net or vb2005? so I can help you also...

Sure... I'm using VB.Net 2005
I’m very sorry do not try to change the application which associate “.sln” files. They are solution files. I changed my extension. it is “.shln” files.
Sorry for my delay

I have this code in VS 2003
Private mobjListener As TcpListener
mobjListener = New TcpListener(5000)
mobjListener.Start()
ByVal client As TcpClient
client = mobjListener.AcceptTcpClient
dim strIpAddress as string
strIpAddress = client.Client.RemoteEndPoint.ToString
but the property Client is protected so...
so i want to get the ip address of the client without using mobjListener.acceptSocket
