Unfortunately I have been trying to avoid just that. The nice thing about a programatically controllable (fictional) tooltip is that it can act normally as a tooltip, but also as a help function when necessary. Thanks though.

That only allows the hover to work or not. If false, no tooltip is shown whenever hovering over whatever has a tooltip (even tried it to make sure). Thanks though, any other suggestions?

Is there a way to show/hide all of the tooltips on a form programatically? I want to use them as sort of a help function by creating a button that toggles their view. I have found ways to show individual tooltips momentarily or allow the hover to work even if the form is not the focused form...

I admit, I need to read through this a couple of times before I understand it all. Thanks again, I appreciate the education.

Wow, still looking at this, huh? Thanks for the follow-up, I'll look through the code you posted.

Good advice, thanks for all the tips/info. I'll keep digging and post back *when* (staying positive here and staying away from "if") I find the root of the problem. Thanks again. joe

Sorry, the synchronized hashtable is for the case of handling multiple writers. The doc's state that a normal hashtable can handle multiple readers with a single writer just fine. I'm stuck on static objects because of two reasons: 1. Ease of use. All I have to do to get data out of the static...

Whoa, there's a lot going on in that sample. Thanks for being so thorough. I'll begin reading through it and try to understand it. However, I am curious if you can tell me what the problem with the below scenario: Thread 1: Read from hardware resource and place results in static hash table...

By the way, there are two different scenarios being used. One is the case I mentioned above with a static class and a bunch of static methods. The 2nd uses a static reference to an instantiated object. Both are causing me trouble, but it is actually the 2nd that produces the protected memory...

Good questions/comments. The reason I need to share info across states is that I have few different hardware resources attached to a pc (usb and pci). There are two threads which update the UI so the user can see what is going on and then there is also a thread which does the actual work and...

Jason: Please question away, I'd definitely appreciate the advice. I've heard that static classes/members should be restricted to functions that do not carry state, but it also seems like a very straight forward way of sharing data across multiple threads. Is there a better way of doing this...

http://stackoverflow.com/questions/313910/can-i-add-an-attribute-to-a-function-to-prevent-reentry Sorry, here's the link I mentioned above.

If changed to a function belonging to an instance object, what's the best way of allowing access to multiple threads? Won't it still have the same issue of the being re-entered on the same thread with asynchronous events? Out of curiosity, can you tell me if my method of sharing data is totally...

Sorry, but I'm a little confused as to where you got the singleton from. I have some idea of how a singleton works, but will it help in my case? I have a function which I want to prevent re-entrance from multiple threads and also the same thread. The lock model works across threads, but not...

I am looking for a way to prevent reentrance on the same thread. The problem is that I have a static function that is called from a form in a couple of ways (button, timer), and I have been using a lock to prevent reentrance from other threads and that portion seems to be working fine. However...
