Hello,
My goal of this project is to create a Console Application that changes IE settings in the registry and launches IE9. I did it on vbscript and want to do it on C#.

Question:
Can i run that console App in the background once the whole executable has the 100% release version ? My manager does not like the DOS background window. :(

Thanks for your help,

What do you mean "in the background", exactly? There is no such thing as "DOS window" for your information.

Is there any reason why you want a console at all?
Does this need a user interface at all?
If not, just make it a windows forms app, and remove the form. Open the "program.cs" file, and replace the code in the Main method.
Presto! No UI at all.

Right, but I already answered exact same thing before, only in different (faster) order: do console application first, and later change to "Windows application".

Solution 1

The problem is not correctly formulated, because you are confused about the notion of "console application", and many other developers do. This is not your fault; this is because Microsoft documentation is not clear enough about it.

So, in fact you simply want something like "console application not showing console". Here is what is meant by this: you have a choice between the two application types: "Console application" and "Windows application". This is misleading. In reality, it means "Anything, windows application or console application, with default console shown" and "anything, with console hidden".

In other words, both options will allow you to use Windows UI in your application, only first options allows to also use console, another will hide console. You can use all combinations. In you cases, you practically start with console application, but change the application type to "Window application", but don't add any windows or forms. In this case, the console won't be shown. You can even use all your console output method via System.Console, it will just go nowhere, but no exceptions will be thrown, no problems at all.

Problem solved.

Thank you Sergey, one last question on your statement what do you mean with "output method via System.Console" can you give me a simple example ?" I am new with C#

Sergey Alexandrovich Kryukov 25-Feb-13 17:08pm

What example?!

System.Console.WriteLine("Hello word!");

I will always work, but, without a console, it won't be shown on screen. Isn't that clear now?

I used your solution but My application runs only few second by it. I wants it runs continueously.

Sergey Alexandrovich Kryukov 12-May-14 11:13am

Well, there can be too many different ways to screw up things. I don't know what do you mean by using my solution...

My mean to say that Console window should be hidden and application should be in running state means I can see it in Task Manager process. Actually It is a server for signalR application that should be in running state to btoadcast any message on event.

Sergey Alexandrovich Kryukov 13-May-14 15:43pm

If the console is always hidden, you just don't need its. Don't use "Console Application" type. That's all.

First and foremost Thanks to you for back to back quick response. What can be alternate of this? Should I go with windows service or windows form application? What do you like to suggest me?

Sergey Alexandrovich Kryukov 14-May-14 0:40am

I can suggest something if you explain your ultimate goals. You cannot say "I want to create a console application", because I'll ask "why"? Why set the registry, why run IE? Who is the user and what if that use doesn't have UI? And so on.

My pleasure.
Good luck, call again.

I'm not sure you know where to set the option, so, just in case:
Console or not, is the option for compilation of the application entry assembly. With Visual Studio, you go to project's Properties, the tab "Application".
