thank you so much for trying to help me. but there was a error on the following line im using visual studio 2005.

IntPtr hWnd = FindWindow("ConsoleWindowClass", null); // retrieve a handle to the console window
ShowWindow(hWnd, 0); // hide the window

Error 1 Class, struct, or interface method must have a return type .

so can you look at the code more closely?

thanks

so much of happy ending...

That's weird. The code works fine here, and I'm also using Visual Studio 2005.
Make sure you defined both functions correctly:

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern void ShowWindow(IntPtr hWnd, int nCmdShow);

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

If that doesn't work, try this:

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern int ShowWindow(IntPtr hWnd, int nCmdShow);

Instead of:

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern void ShowWindow(IntPtr hWnd, int nCmdShow);

Hope that works.

This one should work:

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

Did you get an error on both lines?

If you don't want the console at all, just create a windows application and don't open form.

What article? You haven't submitted any articles here, so I suppose that you mean the forum posting?

Reading your posting carefully only made it less clear. If your program isn't working, what happens exactly when it's "not working"? When you are talking about opening a console window, do you mean the windows command promt?

Maybe he's mixing up post and article?

I am not sure what he means by article, either.

If you look at the top of the page in the menu, to the left of "Message Bords" is "Articles". There is where articles are in The Code Project.

The word "article", however, can be used in several different ways, like for example in "an article of clothing". I don't know which way you are trying to use it, but if it's something other than whats usually regarded as an article here, you have to specify what you mean or it's only confusing.

Articles have a lot of paragraphs and sometimes pretty pictures.

I would just go the WinForms route and not shot any GUI at all. All of the other suggestions work as well.

Why create it as an application at all? Why not create a Windows service instead?

Sorry but you just don't have a clue.
Neither a .Net windows application or a windows service must have a GUI. For the latter its even the common scenario not having any GUI.
Just make a new windows application in Visual Studio, remove the Form and alter the Main method to make what you want. The result will be a program without any GUI or console.

I think the OP keeps calling his posts "articles".

A lot less coding, I may add. No having to call an external function from a .dll to ShowWindow, etc.

Please re-read my OP - I suggested a windows SERVICE, not a GUI based or console app.

Introduction to Windows Service Applications[^]

From the article:
Microsoft Windows services, formerly known as NT services, enable you to create long-running executable applications that run in their own Windows sessions. These services can be automatically started when the computer boots, can be paused and restarted, and do not show any user interface.
