Your best bet is to look into Windows Shell documentation and find out which Win32 calls (or possibly, Registry keys) can retrieve the list of Windows context menu options. That's the easy part. From there, you're gonna have to hook up your application to interop with the Windows shell; so that if you right click on some object in your program, it will allow you to, say, copy the file or text to the clipboard. That will be difficult.
I recommend you look for other options. What is it you want to do?

Hi,
I have a client application that I am writing that connects to a database (MySql) running a server on the network. I would like to be able to communicate from the server with any running client application to be able to send them messages (eg, the server is about to be rebooted, save your work now!). What would be the best way to go about this? I'm thinking that I could have my client listen using the TcpListener class to a port and write a quick and dirty app to run on my server that will use "show processlist" on the MySql server to find everybody who has a connection and send a message to them. Is this a good idea? I've never tried anything like this before.
Thanks
WJ

hi there,
below is just my idea:
1. write an server app on machine that MySQL is running on. this will listen on a port
2. ur client have to register itself to the server app after successfully connecting to MySql. So that the server app is able to know which clients are connecting to server
3. When the MySql is about to rebooted, just broadcast messages to all clients that are connecting to the server

Please anyone. How can I trap the delete key and handle it in such a way that the text in the richtext box will not be deleted.
thanks.

In your form, override ProcessCmdKey method. Then,
if(keyData == Keys.Delete)
{
return true;
}

Can anyone tell me how to fill more form up with rectangles? Like Grid sheet
say size 20 X 20
|
|
|
|

As I told you last time, override the OnPaint method and draw your grid using the Graphics.DrawLine method. Something like this:
<br />
protected override void OnPaint(PaintEventArgs e)<br />
{<br />
Pen p = new Pen(Color.Black);<br />
int width = this.ClientRectangle.Width/20;<br />
int height = this.ClientRectangle.Height/20;<br />
int x = 0;<br />
int y = 0;<br />
for (int i = 0; i<20; i++)<br />
{<br />
e.Graphics.DrawLine(p,x,0,x,this.ClientRectangle.Bottom);<br />
e.Graphics.DrawLine(p,0,y,this.ClientRectangle.Right,y);<br />
x += width;<br />
y += height;<br />
}<br />
base.OnPaint (e);<br />
}<br />
Would work. It would need some cleaning up and you might want to make sure your form size will fit exactly 20 squares because otherwise the last row and column may be bigger than the others. Or you could draw a border around the grid . Whatever works for you.

The source is:
private void Form1_Load(object sender, System.EventArgs e)
{
password.Text = " ";
password.PasswordChar = "*";
}
private void SubmitPass_Click(object sender, System.EventArgs e)
{
if (id.Text == " USER " && password.Text == " PASSWORD ")
{
//here you have put the action that you want that the application
//do when login is true (for example)
this.WindowState = System.Windows.Forms.FormWindowState.Maximized;
//this action does that the window state application is
//maximized
}
else
//here the action that you want that the application would do
//if the login is false (for example)
MessageBox.Show ("Login incorrect. Try again","Login by Rugi",MessageBoxButtons.OK,MessageBoxIcon.Error);
//this action is because the application shows a critical (message box)

Look it!
You go to solutions explorer
right click to the name of your project
click to "add"
then, choose "add windows forms"
put the name that you want in this form, and
click to submit
to another window, you put in the source of a button:
[THE NAME OF YOUR WINDOW] f[A STRING];
f[YOUR STRING] = new [THE NAME OF YOUR WINDOW]();
f[YOUR STRING].Show();

How does one go about finding the type of a given token or variable?
Mainly, I'm looking for a way to tell if a token is a numerical value, rather than a string.
Thanks in advance!

What do you mean by 'token' ? You can use tryparse to find out if a string is a number or not.

I am having trouble closing my application properly. I have a MDI environment. Each child can have a usercontrol loaded.
I have in my Parent the following. All is psudo-code.
ExitApp()<br />
{<br />
if(childForm != null)<br />
{<br />
childForm.ExitFunction();<br />
}<br />
else<br />
{<br />
App.Close();<br />
}<br />
}
in Childform,
ExitFunction()<br />
{<br />
if(userControl != null)<br />
{<br />
userControl.ExitFunction();<br />
}<br />
else<br />
{<br />
}<br />
}
A similar function in the userControl.
I had called a event handler that relaunched the ExitApp function. But obviously, the childform is not unloaded, so this just loops like crazy. How can I verify that the child is unloaded prior to Re-launching the Exit app function.
Thanks in advance...

Can't you avoid calling ExitApp recursively? If not, I think the only way is to add a flag that is set to true when the "else" part executes for the first time and then conditionally skip execution from the next time.
ExitFunction()
{
if (isRecursive)
return;
else
isRecursive = true;
if(userControl != null)
{
userControl.ExitFunction();
}
else
{
}
}
