Arggh. I actually need help(static/shared variables)

Hey guys, I need a hand.

I have a dll that has a static hashtable(object collection) variable that is public. One executable loads it and instantiates the dll and sticks some objects into that hashtable. Now a second exe is supposed to instantiate the dll and with the variable being statis/shared, the second exe should get the value of the hashtable variable as it has been populated by the first exe. But unfortuantly it does not. The varaible is blank. Am I missing anything that I need to do other than make the shared?

:confused: :confused:

Yes Cander you are indeed missing something:D .

If a variable is declared static or shared in a class, that variable will be invisible if that class is instanitated.

eg

Code:

---

public class MyClass
{
  public static int myInt;
  public int myNextInt;

  public MyClass()
  {}

}

---

Code:

---

MyClass mc = new MyClass();
mc.myNextInt = 1; //This is the only member that will show up

//to get myInt you would have to do this
MyClass.myInt = 1;

---

If you want to get values into a static or shared variable, do not instantiate the class with those static or shared variables. Hope that helped

hmm..thought I had tried that before. Ill check again and see if that does it. Thanks.

Actually I think the problem is wanting to share the same object across different exes or AppDomains. You can use remoting to share the same instance or find a way to serialize the object and deserialize it to the other exe. Hopefully I'm wrong though and DevGrp is right or there is an easier way.

I might be mistaken, but I don't believe a dll is shared between applications. It runs in-process.
Your static/shared variable will be visible for one application only.
