The code shown below is with which im messed up............
The problem is 'thread1' and 'thread2' are working simultaneously but the output is not in the correct format. Please check this out and please help with proper solution. I want both load_1() and load_2() to be shown properly. it is very urgent. Waiting for your reply!!!
using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
namespace Loading
{
class loading
{
public static void load_1()
{
Console.SetCursorPosition(0, 2);
for (int l = 1; l <= 50; l++)
{
Console.Write("\\\b");
Thread.Sleep(50);
Console.Write("|\b");
Thread.Sleep(50);
Console.Write("/ \b");
Thread.Sleep(50);
Console.Write("\b");
Console.Write("|");
}
}
public static void load_2()
{
for (int load = 0; load <= 100; load++)
{
Thread.Sleep(10);
Console.SetCursorPosition(25, 4);
Console.Write("{0}%", load);
}
}
static void Main(string[] args)
{
Console.SetCursorPosition(16, 4);
Console.Write("LOADING:");
Thread thread1 = new Thread(new ThreadStart(load_1));
Thread thread2 = new Thread(new ThreadStart(load_2));
thread1.Start();
thread2.Start();
thread1.Join();
thread2.Join();
}
}
}

I would tell you the answer but it will takes me a few days to GUESS what your format is....

I don't have too much expirence with writing to the console, so I'm having a hard time picturing what its actually doing. Assuming the load 2 is working and staying in one place, but load 1 is not, could it have something to do with the fact that on load1 you are not resetting the cursor position each time the for loop "ticks" but are in load 2? I'd imagine that load one goes through the loop the first time correctly, but then the next 50 times through it starts pushing the cursor to (0,3) (0,4) ect.

No, actually both load1 and load2 are workin simultaneously, but while execution the load2 is goin on executing while load1 is workin in the background! this is what irritating me!!

Ah. I'm not really sure what the goal of the program is, but whenever I've done multi-threading apps I generally run into security and cross-threading errors. I've found (at least from a GUI) that it's sometimes easier to create an event handler and then fire the event from the background woker thread. I believe you still need to invoke the event though. Here's a good article on multi-threading: C# Multithreading
Hope it helps

Both the threads are perfectly working!!!! The problem lies with the cursorposition.
Because the load2 function changes the cursor position every time.
Have a Happy Coding.....

hello sir,
can you please tell me, How to run two threads simultaneously? It is a bit urgent!

Don't bother, we will write the code and send it to you for free.
Ok, enough sarcasm. Here is where you start.[^]
Read that, get your hands on it. When you have issues or need more help on a particular area of the multithreading, post your question here.

Hello Masters,
Can you just put some light on which is the best way to invoke function's from a Win32 dll?
I have already studied the following ways:
Solution A: Create Bridge Functions and Use PInvoke.
Solution B: Create a Bridge DLL in Managed C++. If we don’t have the source code for the dll’s this approach would be better.
Also do we need to write a wrapper for each and every function a WIN32 dll exposes?
You need to google first, if you have "It's urgent please" mentioned in your question.

If you are calling small amount of functions or performance is not very critical you can use P/Invoke approach. If performance is an issue, use managed c++
|
|
|
|
|
so you suggest to write a wrapper for the exposed functions from the dll in managed C++ before using them? I knowthat the number of functions in the C++ dll are more than what you would call manageable.

Hi,
I use P/Invoke to call native code. When I am in charge of the native code's API, I keep it as simple as possible, so not to rely on automatic marshaling which tends to cause data copying if one isn't careful.

I don't have the API's code available as well. Not being a C# developer can you please make me understand what is automatic marshalling and how can it be implemented.

either do some research, or ask a specific question, or both.
calling Win32 API functions is handled rather well at this PInvoke site[^]

You are using C++/CLI right? C++/CLI supports C++ Interop and it is more preferable than P/Invoke. So I think Solution B is going to be good.
_AnsHUMAN_ wrote: Also do we need to write a wrapper for each and every function a WIN32 dll exposes?
I think, you only need to wrap functions that you use. Take a look at Nish's C++/CLI in Action, it covers these topics.
