I have a console application and let's say I have another console application (native c++ and I don't have the source) and I want to run that native application with my app like I would start it in cmd.exe.
For example, say my app was named ant.bat, to run it in the console I would type the C:\antroot\ant and it would run and display it's text in that console window.
Now I want to start ant.bat (Process.Start()???) and but have it run in my console window that my managed app is running in. Because if I just use Process.Start() it runs ant.bat in a new console window and closes when execution is complete.
Any ideas?

Try this:
public static void launch( string name, string workingDir )
{
System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.FileName = name;
process.StartInfo.WorkingDirectory = workingDir;
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.Start();
System.Console.Write(process.StandardOutput.ReadToEnd());
}
You could also throw in process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;, but I don't think it's necessary.
By the way, this also answers the gcc question below.

Thanks that works just as I like.
I have another question though. If, for example, I wanted to set an environmental variable with my computer I would go like this in the command prompt....
<br />
set JAVA_HOME=C:\jdk1.3.1_16
How would I do this programmicly in C#?
Thank you for your time.

Hello,
I am using UDP protocol to broadcast a packet on the network. After I send this packet, some devices on the network answer with a UDP datagram packet containing some information.
My problem is that whenever one of these devices answer, (I know I get the packet because the Socket.Receive function returns me the data I am waiting for) I don't know who this packet is coming from. I am looking for a way to know the IP Address of the packet sender.
This is my code :
<br />
IPEndPoint Broadcast = new IPEndPoint(IP, 2000);<br />
EndPoint BroadcastEP = (EndPoint)Broadcast;<br />
<br />
socket = new Socket(System.Net.Sockets.AddressFamily.InterNetwork,<br />
SocketType.Dgram, ProtocolType.Udp);<br />
socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1);<br />
socket.SendTo(msg, 0, msg.Length, SocketFlags.None, BroadcastEP);<br />
Then, if I use the socket.Receive function, I get the payload of the packet but not the header information. Is there a way to get this information (Source's IP Address) with System.Net.Sockets or with System.Net.Sockets.UpdClient ?
I thought I could get this information by using socket.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.PacketInformation, ... but I just can't seem to figure out how to use it correctly.
If anyone knows how to do this, it would be greatly appreciated!

Hi
When I run g++ (to compile) using process.start I get the error: "g++.exe: Main.cpp: No such file or directory"
If I run g++ using the same arguments from command prompt it runs fine. whats going wrong?
cheers

You need to specify the full path of the Main.cpp file when you run it using Process.Start, or, you need to set the current directory to the directory where Main.cpp resides before starting the process.
This is because a process spawned using Process.Start by default, has its current directory set to the application directory of the parent process.
Regards
Senthil

Thanks a lot! How can I "set the current directory to the directory where Main.cpp resides before starting the process"
Cheers again

You can use the ProcessStartInfo's WorkingDirectory property.

I was wondering if anyone can point me in the right direction to replicate the Internet Explorer-style Menu Bar in C# using Windows Forms?
I can easily create the menu using the toolbar control, but I run into problems trying to size the text correctly without the icon. Either I get too much space on the top (setting the toolbar TextAlign to Underneath), or I get too much space to the left (setting to Right). How do I get rid of the space?

Show() will allow the user to continue to use the application and bypass the login. ShowDialog() is a modal function, so the application can't be used until the dialog is dismissed. In your case of trying to obtain login data you would want to use this method.
In the OnLoad event for your main form create an instance of your login dialog and call ShowDialog on it from there. Obviously, you would check the DialogResult and handle it appropariately.

the first form closes because you call this.close. The first startup form probably has the stathread method which startsup the application. When you close this form it takes all the others forms with it cause it's under the same process. What you can do is move the stathread method to the login form and if login is succesful you can show the main form.
