Just put some code in your event to read the button text for example:

private void Button_Click(object sender, EventArgs e)
{
Button button = (Button)sender;

if (button.Text == "button1")
{
// do this for button 1
}
else if(button.Text == "button2")
{
// do this for button 2
}
else {}
}

Alternativly you can add seperate Event handlers for the differnt buttons. There are many ways to do it.

Hi,
is there any way or method to find out the Ascii code of the character that is typed in the text box.
Actually, i'm trying for a textbox that only accept numeric values/symbols (that is 0 to 9). Because i don't want to let my user to enter any character or special symbol except decimal point.
if anybody have any idea than please do let me!

With Thanks.

Add an Event handler to the text box

this.textBox1.KeyDown += new System.EventHandler(this.textBox1_Keydown);

This allows 0-9 and backspace.

private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
if(!Char.IsNumber(e.KeyChar) && e.KeyChar != (char)8)
{
e.Handled = true;
}

}

There is no Google Talk API, the only way you can control things is to write a program that uses the Windows API to control the Google Talk window. i.e send mouse clicks etc etc. Which is pointless if your at the computer because you can just use the Google Talk app.

You can call the API just the same in C# but you need to include the System.InteropServices; namespace. I think this article might be what your looking for:

Switching Panels on a Form with Control.Remove Control.Add

Hi guys,

I have a single form to control my application and rather than use multiple windows it switches out the main panel depending on what view the user wants.

My problem is that its not very effective and wondered if you can point me in the right direction to get a flicker free app.

Should i go with this idea or is there anotehr solution?

Add all panels to the Form at run time (shouldent be a problem since there are only 3-6) Show the current panel while Hide the rest. While having a seperate thread update the 'main' and sleeping panels every say 1/2 second.

Thanks,

Darren

Code is like this:

public void ShowHome()
{
this.Controls.Remove(currentPanel);
currentPanel = new App.Main.MainPanel();
this.Controls.Add(currentPanel);
currentPanel.BringToFront();
}

public void ShowSecond()
{
this.Controls.Remove(currentPanel);
currentPanel = new App.Main.SecondPanel();
this.Controls.Add(currentPanel);
currentPanel.BringToFront();

}

what i was thinking from my previous post was to add all panels at runtime and just .Hide() and .Show() them but have a second thread update them all periodically.

There are 2 ways to do it:

1. Use this.SuspendLayout() before your code and this.ResumeLayout(false) after your code.
2. Use Visible = true or false to Show or Hide panels.

Re: Switching Panels on a Form with Control.Remove Control.Add

Yeah i tried using .Hide() .Show() (not sure if that works the same as Visible and sets the same flag) but trouble is the panels generate content on specific things so if something has changed and i switch to the new panel the panel hasn't updated if you see what i mean.

Any ideas?

Ok i tried quite a few things but i think i have a new solution:

Im going to create a TemplatePanel Abstract class that derives the Panel class and contains a Update() method, of which any app panels must derive.

Then i will run a thread that periodically calls the Update() method for all panels if the application is not minimised.

If anyone has another solution then please let me know,

Thanks

Which method is used to get IP's of nodes on LAN?

How We can get information about the nodes attached on LAN programatically ven v r on server?Is there any method already present in C#?

thanks in advance

Maybe you can read the ARP Table? If not why not read your own ip (the server) then ping the subnet to see who is alive. i.e. ping 192.168.1.2 -> 192.168.1.255

this might help on the ARP although its in C++

The ARP table might only hold ip addresses of computers it had reason to communicate with though, not sure on that.

closing a windows form by itself

Hi
I am writing a windows application using C# for performing a task as scheduled. Now I am calling a method which does the needful inside the form1 constructor
which is inside the main method like this:

static void Main()
{
System.Windows.Forms.Application.Run(new Form1());
System.Windows.Forms.Application.Exit();
}
now what is happenning is that the control does not reach this statement
System.Windows.Forms.Application.Exit();
and I need to manually close the form which is not what I want.
I want the application (and the form) to close by itself.

How can i do this.

Thanks in advance,
Aryan.

System.Windows.Forms.Application.Exit(); does not get executed because your program is running an open window on a thread. It will never reach System.Windows.Forms.Application.Exit(); because when you close the window Dispose would have been called already.

Can i ask why you are using a window? If it is to run a scheduled task why not just create a Console Application, this will exit once it has finished executing. If you have the window so you can enter data about what it is you want to run, why not just add switches to execution of your console application like Start -> Run 'myapp.exe "path to filename" "time to start"'

hi all,
I have a class which has a functions to generate XML files based on given parameters, Move these files from one machine to another and execute these files over a database.
Iam able to call these functions fine on a button click event.
It is required that the functions all be automated ..
I tried this by calling these functions from a windows service(C#) in the OnStart() method but i see that they are not executing...
I am not able to debug the windows service.
How can i automate the execution of my class functions using windows service or some other kind of scheduler?

Thanks in anticipation
