How to create global variable
-
Hi all, In my application i have 5 forms. I would like to store some value in global varialble which can access by any forms in my app.I have try to create a get/set class and i declare a public object in form let said form A. But i can't access the object in form B. My example coding as below: Class GetSet:
private String _name; public String name { get{return _name;} set{_name = value;} }FormA:public partial class FrmA : Form { GetSet gs; public FrmMain() { gs = new GetSet(); gs.name = "cocoon"; } }FormB:public partial class FrmB : Form { GetSet gs; public FrmMain() { console.write(gs.name); } }Can anyone guide me to slove this out. thanks in advance regards cocoon -

You can't. However, you can create a static class which is quite similar to what you are asking for. There are plenty of examples on Google.

If you thought that FrmB would do anything but crash, or had any chance of seeing hte value 'cocoon', you need to do some serious reading on OO, because you've misunderstood quite a bit.

I have read through the static class and it useful to me. Then, Christian Graus, can you please explan a bit more to me why would you said i am misunderstood OO concept? Thanks in advance. ;) regards cocoon

It will help in state maintainance in the application.
