hello friends
i'm converting a c program to c#...
i need to use the header file content from tat program...
pls help me out wit an idea how to use those declarations and functions in c# from c header files
im aware that c# doesnt support header files....help me out wit any alternate idea
the quieter u become more u hear
|

simple. Just put your declarations and functions in your main class.
if you need access by multiple classes then use a static class as a kind of 'header' class
|
|
|
|
|
There is no way to use those files. You simply have to rewrite the declarations in C# code in an appropriate place in your project.
|
|
|
|
|
wit is not a word. And, it sounds like you need to learn C#. C# doesn't need headers, it auto includes everything.

You couldn't figure that out on your own?

Simple; put an # include directive in your C# and run it through a C pre-processor.

Thread threadSocket = new Thread(new ThreadStart(StartSocket));
threadSocket.Start();
}

{
SocketServer mySocket = new SocketServer();
mySocket.SocketDataArrival += new SocketServer.SocketServerHandler(ShowDataArrival);
mySocket.InititateServer();
}
void DisplayMessage(string stringMessage)
{
TxtBoxMsg.Text = stringMessage;
}
static void ShowDataArrival(object a, SocketServerArgs e)
{
DisplayHandler d = new DisplayHandler();
d.Invoke(e.Message);

thanks for your idea but I had tried the solutions recomended before and it still doesnt work...
1. the textbox control can't be seen in the calling class thread.
2. I incountered an error when i use a delegate & invoked method as advice by most of the experts.

Dont know if is the best option but you can use a static property and then create an event handler that is fired when that property changes. i.e. thread sets property to required string
Then your text box can listen for the event and load the static property value as its text

thanks for your idea but I had done it but it doesn't work.

"Synchronization in Threads
When we have multiple threads that share data, we need to provide synchronized access to the data. We have to deal with synchronization issues related to concurrent access to variables and objects accessible by multiple threads at the same time. This is controlled by giving one thread a chance to acquire a lock on the shared resource at a time. We can think it like a box where the object is available and only one thread can enter into and the other thread is waiting outside the box until the previous one comes out."
As quoted from a Code Project Article[^].

hi, god day,,,
i tried to run your corrected code but it will still give the same error
"Cross-thread operation not valid: Control 'TxtBoxMsg' accessed from a thread other than the thread it was created on."

your suggested code did not run, however i still want to thank you for your effort done. your code really help a lot to solve my problem... I made a little adjustment on your corrected code....
again, thank you very much
using System;
using System.Windows.Forms;
using System.Threading;
namespace webbrowser
{
public partial class WebBrowser : Form
{
public delegate void DisplayHandler(string stringMessage);
//public event DisplayMessage;
public WebBrowser()
{
InitializeComponent();
}
private Thread threadSocket;
private SocketServer mySocket;
private void WebBrowser_Load(object sender, EventArgs e)
{
threadSocket = new Thread(StartSocket);
threadSocket.Start();
}
public void StartSocket()
{
mySocket = new SocketServer();
mySocket.SocketDataArrival += ShowDataArrival;
mySocket.InititateServer();
}
public void DisplayMessage(string stringMessage)
{
this.TxtBoxMsg.Text = stringMessage;
}
void ShowDataArrival(object a, SocketServerArgs e)
{
//DisplayHandler d = DisplayMessage;
//d.Invoke(e.Message);
DisplayHandler d = new DisplayHandler(DisplayMessage);
this.TxtBoxMsg.Invoke(d, new object[] { e.Message });
}
}
}
