when i click on the rich text box, how can i get the character number?
like 7th character from the start?
|
|

The SelectionStart property gives you that. SelectionLength gives the number of characters selected from SelectionStart.
For the reverse, ie. selecting text when a node is clicked, that's easy, you can just call the Find method on the text box and select it.

Hello everyone!
I'm designing datetime textbox by C# & ASP.NET, I want data type is datetime but users access in my website enter datetime such as mm/yyyy.
How can I do?
Please tell me!
Thank you!

You can simply parse the TextBox into a DateTime. If the entered Date is of a recognized format, this will automatically convert the string into a DateTime.
e.g.:
DateTime myDate = DateTime.Parse(textBox1.Text);
If you want to force the users to use a certain format, check the textbox for the compliance before you parse it. Show some error-message if it does not.
Cheers

how to use char** from C library to C# using invoke.
[C]
int TestFn( char** UserBuffer);
[C#]
[DllImport[("My_C_DLL")]
public static extern int TestFn( ref IntPtr UserBuffer);
[USE in C# CODE]
IntPtr pBuffer = new IntPtr();
TestFn(ref pBuffer);
When I used it like that, I did get NULL values. What are we doing wrong here?

Hi!
A RichTextBox where you can't select the text (basically a label with formatting) is a by-product of my article here[^]
I guess that's exactly what you want.

HI，
I have seen your implementation of not seleting in RichTextBox. But sorry, I want the richtextbox can get focus yet not selecting. How to do?

Hi!
What's the point in allowing the RTB to receive focus when the user can't do anything in it?
A label can't receive focus either, so why should a label with formatted text?

Hello csharpers,
I'm seeking for an option (region) to define a range were my variable definitions are protected against access by the IDE which mixes always control definitions with my own.
Does someone know a solution.
Thank you in advance

AFAIK, the IDE only modifies whatever is in the "Component Designer generated code" region. Whatever you write elsewhere won't be modified by the IDE.

Don't know why but ...
Variable definitions are placed elsewere only the variables, class, components initializations are placed in that region.
Some ideas to change that ?

Hi there!
this problem costs me a couple of days and I still haven't had the answer. I use function System.CodeDom.Compiler.CompileAssemblyFromSource() to generate a dll file on disk, just generate, I dont want to use it in my running application at all, but when the dll has generated, I make some ajustment and built it again, it rejects my request with an IOException: the file is begin used by another process.
I look for the generated dll in my running process' process modules and found it!!  so what should I do to build my dll again and again.
Help me plz! thanks a lot

I am working on messenger.On each client side there is an interface that listens the new user request and opens a new window for chatting.But when i use to show the application halts i am writing the code if some one know the solution please Let me know.
Thread thread=new Thread(new ThreadStart(reciveConnection));
thread.Start();
Socket sock;
public void reciveConnection()
{
TcpListener tcp=new TcpListener(4600);
tcp.Start();
While(true)
{
sock=tcp.AcceptSocket();
Client cli=new Client();/////Initiating object for new clent window
cli.Show();/////Here problem Accours.
}
}
|
|
|
|
|
should u not declare Socket sock above the thread.Start()?
There is a good chance that the sock=tcp.AcceptSocket() will be called before the socket is actually declared!

You can't display a modeless dialog on a thread that doesn't have a message pump. Without a message pump, the window (cli) won't be able to process messages it receives, that's why the application appears to hang.
If it is okay for the dialog to be modal, call cli.ShowDialog() instead of cli.Show(). Otherwise, you need to start a separate thread with a message pump (you've to call Application.Run()).
