Hello!

Everthing works, but he don´t open myTimer_Tick!!!

open takes the value from the textbox, then * 1000 = 5sec!

public Form1()<br />
        {<br />
            InitializeComponent();            <br />
        }<br />
<br />
        void myTimer_Tick(object sender, EventArgs e)<br />
        {<br />
           System.Diagnostics.Process.Start("winword");    <br />
        }

/*static*/ void Listen()<br />
        {<br />
<br />
<br />
            while (true)<br />
            {<br />
                try<br />
                {<br />
                    data = new byte[1024];<br />
                    received = networkStream.Read(data, 0, data.Length);<br />
                    if (received == 0)<br />
                        break;<br />
<br />
                    string get = Encoding.ASCII.GetString(data, 0, received);<br />
                    var send = get.ToByteArray();<br />
                    //Console.WriteLine("Received from TCP Client: " + get);<br />
                    networkStream.Write(send, 0, send.Length);<br />
<br />
                    if (get.Contains("open_ever_x_sec"))<br />
                    {                        <br />
                        string[] get_Split2 = get.Split('~');<br />
                        int open = Convert.ToInt32(get_Split2[1]);<br />
                        timer1.Tick += new EventHandler(myTimer_Tick);<br />
                        timer1.Interval = open * 1000; // Millisekunden<br />
                        timer1.Enabled = true;                                             <br />
                    }<br />

are you sure that this condition is true

if (get.Contains("open_ever_x_sec"))

put a break point in there and see if it get called or not. If it does then check that is Tick event attached with timer1 and what is the value of open

yes it get called!
And open takes the correct value!
He doesn´t open myTimer_tick!!!!

It suppose to get called, btw write following line after InitializeComponents()

timer1.Tick += new EventHandler(myTimer_Tick);

and remove from while loop.

try adding
timer1.Start();

check if VS didn't already assign event handler

If that doesn't work, try this:

Timer time1 = nre Timer();
time1.Tick += new EventHandler(myTimer_Tick);
time1.Interval = 2 * 1000;
time1.Enabled = true;

doesn´t work!

nre Timer ;awaited!!!

I have tried the code in a new windows form application i have put this code into button click:
timer1.Tick += new EventHandler(myTimer_Tick);
timer1.Interval = 10000; // Millisekunden
timer1.Enabled = true;

and that above the Button_klick
void myTimer_Tick(object sender, EventArgs e)
{
mciSendString("set CDAudio door open", null, 127, (IntPtr)0);
}

And it doesn´t work!

Can somebody try it in a new windows form application and when it works can he send me the full code!!! Please

void myTimer_Tick(object sender, EventArgs e)
{
        MessageBox.Show("1");
}
void listen()
{
        Timer time1 = new Timer();
        time1.Tick += new EventHandler(myTimer_Tick);
        time1.Interval = 1 * 1000;
        time1.Enabled = true;
        time1.Start();
}

I Have tried this at windows form app and it worked. However i coudn't do with console app. I noticed that console app timer doesn't work, so i found alternative solution:

Thanks, alright your code works in a new Windows Form Application but with not!
I have tried nearly everthing but it doesn´t work!!!
this code also works, but not by Server and Client:
for(int i =0;i<int.MaxValue;i++)
{
System.Diagnostics.Process.Create('winword'); // Word
System.Threading.Thread.Sleep(10000); // 10 Seconds
}

I don´t why but it doesn´t work!!! Confused | :confused:

Thank you at all!

I assume you meant witg your app NOT.

Did you create project as service?

Hi,
It works but it doesn't!

I have questions about the Listen method. Does it block at

received = networkStream.Read(data, 0, data.Length);<br />

until data arrives? What happens next, that is, does it loop around and block again waiting for more data?

Alan.

Timer works in diffrent Thread, as soon Timer.Enabled set to true, it will send event every time an event Ticked and it doesn't matter how occupied is the main thread

Alan N22-Aug-09 13:25

Hi,
The code fragment shows that he is using System.Forms.Timer which raises events on the UI thread.

Saksida Bojan22-Aug-09 18:58

I Think you are on to something.

Timer time1 = new Timer();
time1.Tick += new EventHandler(myTimer_Tick);
time1.Interval = 1 * 1000;
time1.Enabled = true;
time1.Start();
while (true)
{
            // do nothing
}

This above code doesn't fire anything, so i think he needs to create timer in another class, while that class is created in a diffrent thread using System.Threading

It doesn´t work!
I have tired it with a new server and client and it doesn´t work here is the Server and Client Source code with timer:

if by somebody works, please post me!

Hi,
Finally you post code showing the root cause of the problem. The Listen method is running on a secondary thread and the System.Windows.Forms.Timer is designed to operate on the UI thread only.

You may

1) Wrap the timer manipulation code in a method and use this.Invoke and a method delegate to force the code to run on the UI thread.

OR

2) Change the timer to either System.Threading.Timer or System.Timer.

Option 2 would be the cleaner solution.

Alan.

nhqlbaislwfiikqraqnm23-Aug-09 23:36

23-Aug-09 23:36

I tried the the second solution, but it doesn´t work!
Maybe i habe made something wrong can you send me the code how do you mean!
Please

Hi,
Your most common response to any suggestion is "it doesn't work" without any backup information.

Please post a relevant code sample with details of the test you performed and the result of the test.

Alan.
