How could I set up global value for my DLL?

I am confusing about my dll which is for ArcMap.

There are 4 forms, one is Property Setting Form which will provide certain value to other forms, at present, I am using form.hide after user setup the property value, then other forms could directly get those values. But I need to unload the Property Setting Form after user sets up those values, so could some one help me to set up global value for this dll or other ways to solve this problem? thank you for your time and attention.

I don't think this is possible - at lieast I can't think of anything right now -

you may have to persist this data you need to temp file (.ini) or to the registry - somewhere that the dll method knows about and can retrieve.

alaazz,

Can't understand what you mean.

You may want to set a Get Property so that your app could retrieve those values...
