I don't see why that should happen, what is the 'stuff' that you do ?

set a property which checks if this.OnChange != null and if not it triggers it.

nevermind, I found the problem while debugging.

It saved in the event B from some reason.
I just added: [field: NonSerialized()]
to every event.

It works fine now.
Thanks anyways Smile | :)

ApplicationDeployment currentDeploy = ApplicationDeployment.CurrentDeployment;
// Check to see if an update is available on the server
if (currentDeploy.CheckForUpdate())
{
// One is available, go get it
currentDeploy.Update();
// Make sure you save application state here
DialogResult dr = MessageBox.Show(
"Update downloaded, restart application?",
"Application Update", MessageBoxButtons.YesNo);
if (dr == DialogResult.Yes)

i need to convert from network stream to byte[]...

please help

What does the code look like ? ( I'm curious how a network stream looks, is it just a stream object ? )

TcpListener tcpListener = new TcpListener(2112);<br />
tcpListener.Start();<br />
TcpClient tcpClientIP = tcpListener.AcceptTcpClient();<br />
NetworkStream nsIP = tcpClientIP.GetStream();<br />
StreamReader srIP = new StreamReader(nsIP);<br />
string resultIP = srIP.ReadToEnd();

as u can see the last result is a sting... but before that i need it to be byte[] because i am using an encryption...

OK, converting a string to a byte[] is pretty easy, why do you need to convert it *before* it's a string ? You read a stream using the methods it offers, does it offer one to read a byte [] ?

Encoding error.. help guys:(

the received stream is encrypted... and the encryption methode i used is dealling with the byte[]
so i need to convert the stream to byte[] first and then decrypte the byte[], then convert it back to string

Not sure why you're getting that here, perhaps you've made it nvarchar in the table, and it's still varchar in the proc ?

My problem is that the main menu cannot be actived by call MenuItem.PerformSelect in OnClick event of one button.

but now, i resolved this problem by calling <sendkeys.send("(%)")> on OnClick event. that is say i only simulate pressing "Alt" key of Keyboard. should not call MenuItem.PerformSelect.
