Public Variables? (Solved)

[Tec-Nico]

How and where do I declare variables that will be used by all my Forms?

Thanks in advance

In a Module.

[Tec-Nico]

Sounds logic, indeed... Like on VB... How do I get to make a module?

Oh... and also... Lets say I have a comboBox... How would be a procedure that would populate it?

Like:
comboBox1.Items = GetItems("DoubleType");
?

In this case I would have a Dictionary and I would get all of those that are Double Typed in my dictionary... Any ideas? (This has to be handed in in less than an hour)

No in C#...

Wrap your variable in a class and make them static.

[Lethal]

Just enumeate through the collection and query the GetType() method and use the typeof() method to do the comparison.

Lethal, I am really tired.. Could you please give me an example? I would really appreciate it... You will save my life (and my grade too) if you do...

Thanks in advance

Example 1:

namespace VSSolutions.Sprocs 
{
    public class Sprocs 
    {
        private static string addUser;
        public static string AddUser 
        {
	get { return addUser; }
	set { addUser = value; }
        }
        public static void AddUserToSytem(int userID) 
        {
	// Call Stored Procedure
        }
    }
}

Example 2:

using System;
using System.Collections;

public class EnumerateTypes 
{
    public static void Main() 
    {
        ArrayList types = new ArrayList();
        string name = "John Doe";
        double age = 23;
        types.Add(name);
        types.Add(age);
        foreach (Object o in types) {
	if (o.GetType() == typeof(System.String)) {
	    Console.WriteLine("String");
	}
	else if (o.GetType() == typeof(System.Double)){
	    Console.WriteLine("Double");
	}
        }
    }
}

Damn, thought this was the VB.NET forum. Do what Lethal said, put them in a Utility class and declare them as static.

(I was given more time since nobody finished) Thanks Lethal... I still don't grasp all of it though why is the main there? Should I remove the main from the Login Form I have it on?

Do I need to use get and set? I just wanted to be able to Declare something like...

myDictClass myDictionary;
myDictClass2 myOtherDictionary;
int i;
bool FinishProject;

and maybe some initialization as...

FinishProject = false;

Would I need to do the set and get for this too? I am sorry but I really don't get why there isn't a given place on C# to make public variable declarations for all forms in a project.

Thanks again!

And where should I declare a new instance of the class?

[hellswraith]

namespace MyApplicationNamespace
{
    public class GlobalVariables
    {

        private GlobalVariables
        {}

        public myDictClass myDictionary; 
        public myDictClass2 myOtherDictionary; 
        public int i; 
        public bool FinishProject;
    }
}

You can use them in your code by simply doing this:

bool myValue = GlobalVariables.FinishProject;

Also, you can check this sample I put together, you can take ideas from it:

Thanks, I will try that right now... Please keep in touch if I can't make it work..

Isn't it necessary that I declare an instance of the object? will the changes made to this variables will remain persistent while the project is running?

Oh, and I think the link won't work since it says "localhost"... (I already tried it also)


Thanks!

[Tec-Nico]

That worked it out, thanks a lot!
