hallo
I wrote a small system tray application, and I would like to make it react to shortcuts.
How could I achieve this?
thanks in advance

I do not think that you can do that without hooking keyboard events globally.

Hi!
im new to encryption and would appreciatelittle help
currently im using CryptoStream(RijandelManaged) with NetworkStream and it seems to work except that i dont get all the data right away.
this is my current code:
RijndaelManaged r = new RijndaelManaged();
cryptoReadStream = new CryptoStream(netStream, r.CreateDecryptor(key, iv), CryptoStreamMode.Read);
byte[] buffer= new byte[10000];
cryptoReadStream.Read(buffer,0, buffer.Length);
the problem is:
1.cryptoStream.Read blocks until 10000 bytes have been recived, unlike NetworkStream.Read which returns when theres is nothing more to read,
this is a problem beacuse if the server only writes 10 bytes then ill have to wait forever before i can diplay the results.

You can read it to an intermediate MemoryStream, still cryptografed, and after finishing reading you use the cryptoStream to decrypt the data.

I need a pointer to a good article on delegates/events in client/server apps.
Specifically I need the server side to raise an event that all logged on clients can receive and react to.
The server does not need to know if any clients received it.
Searching available resources just gives too many results.

Did you handle the FORM's KeyDown event, or one of the buttons??
|
|
|
|
|
Yeah, the following code :
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Down)
{
MessageBox.Show("Pressed");
}
}
|

That code snippet will deal with the down-arrow key of your keyboard, and is unrelated to the four buttons your picture is showing, one of which displays "Down" as its Text.

You need to fire events for all 4 buttions and form. If a buttion has focus(If you press tab and then you will see sometimes a dotted border around text.), it will fire an event from a buttion not form-

No thanks. I'm not going to download, open and study some ZIP file.
You better figure out the difference between keyboard keys and Windows Buttons, then show us the appropriate part of your code if that is still necessary.

When you say this:

Are you clicking a button or pressing a keyboard key?

I'm pressing Key.Down of keyboard.

It is the use of Keys.Down that is the problem.
If you change your code to if (e.KeyCode == Keys.K), for example, and test it you will find that the event does fire.
So what you need to do is research what the difference is between the way Down and 'K' are processed.

No, it doesn't fire.
this is the application http://www.mediafire.com/?mh01etlgm5z[^]

It does fire, only Key.Down is the problem. If your application doesn't fire the event, then it's something wrong. I just tried it, it fires event if Keys.A, but no event in Keys.Down.
