Hi manoj

In my application, form1 is the main form and form2 comes from ShowDialog().
and now i want to open/activate form1 from form2 which is already hidden in system tray.

Thanks

Since form2 is Modal dialog in ur application, you will not be able to get the form1 over it. what you can try is making the form2 modeless by running it with Show() function. In this can you can show form1 over form2 as form2 is modless now.

Hello,

If you are using ShowDialog in Form1 to show Form2, code stops at this point and will only go if you close the form2.
In form2 you have the posibility to set the DialogResult and check it afterwards in form1.

//from1 code:
Form2 f2 = new Form2();
if(f2.ShowDialog() == DialogResult.OK)
{
   //do stuff here
}
else
{
   //do stuff here
}

What you can not do is showing and interacting form1 while form2 is still open
If you whant to do this you would have to use Show() instead of ShowDialog().
If you then need to call a method or set a field in from1 from form2 you should read this nice article from ColinAngusMackay:

Hope it helps!

All the best,

How to add progress bar to subitemof listview ?

29-May-07 21:22

You're getting bad answers because your header is totally wrong. Your wording implies you have two forms on the one PC. You need to choose a port, listen to it with form2, and transmit to it with form1. Surely there are articles on what is essentially a chat program, here on Code Project ?

Hello,

I think fatsest way would be a loop!

byte[] b1 = new byte[5];
b1[0]=1;
b1[1]=2;
b1[2]=3;
b1[3]=4;
b1[4]=5;

byte[,] b2 = new byte[2, b1.Length];

for(int x=0;x < b1.Length;x++)
{
    b2[0,x]=b1[x];
}

All the best,

Martin

Does anyone here have a source code on internet speed?

What i mean is, I want to implement a program which can detect the speed of an internet. or just like the http://speedtest.net

I have a code already on client to server connection
using Net.Socket

Can you help me please. I`m a newbie in C# and also newbie in codeproject.com

Thanks guys.

just want to know everything...that`s it.

A speed test works by tracking the progress of a fair size file. So, you can set up a big file and download it, and see how long it takes to come down. Obviously, you can only test speed so long as your connection is slower than the server of the file. It seems to also be testing the speed of ping, that's also a reasonable test.

I recommend you buy a beginner book on C# and work through learning hte language a bit, if you're really new to it. Too many people here will never know how to code, because all they are learning is how to ask for snippets and paste them into their apps.

this is what i want and like "snippets".

Yeah i have lots of books here of C#. I just want to go on directly on my app. broadband speed test Smile | :)

could you please help me.
this is the part of code and it works fine.

for server
IPAddress IPAdd = IPAddress.Parse("192.168.1.8"); // my local ip address.
// initialize listener
TcpListener myList = new TcpListener(IPAdd, 8080);

for client
TcpClient myClient = new TcpClient();
Console.WriteLine("Connecting to server...");
// use the specified ipaddress and port in server side

myClient.Connect("192.168.2.226", 8080);

you have a code on this->

You're connecting to yourself here, right ? That's not going to test your web connection.

No, I don't. It just seems like a reasonable thing to test.

Hi Friends,

I have an Arrlist which carries 10 strings like :-

arrList.Add("aaaa");
arrList.Add("bbbb");

......... upto 10 strings.

How can i generate these strings randumly..i have tried like
randum o=new random(10);
int i=o.next(1,10);
but in this case i is always 9.

thanks

What you need to do is create your Random class as a member variable, if you create it every time you need a random number, the numbers get less random.

Robert Rohde29-May-07 20:50

Remove the '10' out of the Random constructor. It is the seed for the generator and by giving it always the same number it will also always procude the same numbers. Removing the argument from the constructor will result in a time based seed generation which should always be different.

Wait for what? Do you want it to do "other task" while waiting, or after waiting?

That is kind of what you're generally avoiding when you use threads. You need to better explain what you're trying to do, it sounds like you don't want to use a thread at all.

Hi,

To get this implemented you need to have a smart design.

You can implement somthing like:

Suppose thread #2 is waiting for thread #1 to finish the job, and you want thread #2 to do somting while its waiting for thread #1.

In thread #2 implementation you can do the following:

while (true) // this is the wait loop for the thread #2
{
//check if thread #1 has completed its job
if (yes)
exit from this wait loop.
else
perform the task you want thread #2 to do, while waiting.

//Sleep for say 0 so that others thread gets quantum
}
