 Hi,
I'm looking for a solution to pass a data struct between threads without using a global struct variable.
When i use a local struct variable in THREAD1 and send it with postThreadMessage to THREAD2,
The variable is out of scope and in the debugger get a null pointer (in THREAD2 scope).
If you have a better solution please share.
Thanks.

You can either do that, or use heap-based memory.

Thanks for the fast answer,
I tried that and got a null pointer.
It must have more robust solution

Then you must've done something wrong. Without a relevant code snippet, suggestions will be guesses at best.

Does RegCreateKeyEx() works when registry key has been disabled by administrator??????

Highly unlikely.

You can't, unless you, like the one that 'disabled' it, is also an administrator.

If you have any argument, use the forum to make it public.

Reading your further messages, I think there is some confusion.
An administrator can set policy to disable regedit. In which case, that has no effect on any program you write using the Reg API functions.
If the permissions on a key have been so that you can't access them, then the answer is to ask someone in authority nicely to fix that. If you don't give them a good reason, tough.
If you have the authority, then you can use REGEDT32.EXE to play with permissions on registry keys. It looks similar to regedit, but is a lot more powerful (and dangerous!).
If you want to change the permissions on a key programmitcally, then that is a complex job, involved SIDs, and all sorts of things I feel only pertially qualified to discuss.
Also, you need permission on a parent key to do that - if you don't, the answer goes back to "tough".

Hi,
I have regitsred key under AllSystemObjects in registry for context menu. It is working fine for all files and folders But when I right click on .lnk file, my menu option is coming twice.
How can I restrict it to come once.

Pther,
I'll give you credit for persistence! I'm impressed you found a better registry key than '*' for your shortcut handler - I failed. Mind you, you weren't paying me for an answer...
I'd strongly recommend sysinternals regmon program for sorting out any issues with the registry.
Is you handler called twice? I'm guessing you still have the * key setup - so are you called once for the lnk file, and once for the file the lnk points to?
The debugger should help you. If I haven't already told you, Michael Dunn's excellent shell series has information on debugger extension handlers in its first (or second) article.
First find out *why* you're getting two calls, then worry about "fixing" it. Maybe you want to give slightly different menu optiosn if it's a lnk file? Check the path you're being given to make sure both times are the same? If they're not, filter on that... Etc.
Iain.

Hi,
I have a thread in my application having a pipe (Created in Blocking Mode) which waits for the client to write to it.
Once pipe is read the post a message with the read pointer casted to Wparam to the main appication and waits for the next read.
Now the problem Iam facing is that by the time the application process the message the pipe is again read , so the memory gets overwritten.
Can anyone let me know how to overcome this problem?

Don't overwrite your memory?
Seriously. You read from a pipe into a section of ram that you've allocated. Try allocating a fresh chunk each time, post a message to some other part of your process with the pointer to that memory as (eg) lParam, then delete the message in that part.
If you use a buffer allocated on the stack (ie, inline in your procedure), and then keep reading on top of it, then you've volunteered for your own problem.
I would also worry that if you're processing messages slower than they're arriving then you may get problems. If it's just the occasional one, and most are fast, then you're fine.
Iain.
