For the sake of debug -- is there a way to determine that this thread is a UI thread (one based on CWinThread)?

IsGUIThread(...) is not an MFC function, and is only available on WinXP (and above).
Peace!

What is a "GUI thread?"
"Normal is getting dressed in clothes that you buy for work and driving through traffic in a car that you are still paying for, in order to get to the job you need to pay for the clothes and the car and the house you leave vacant all day so you can afford to live in it." - Ellen Goodman

I think a thread that has some user interface with the user is called GUI thread. I mean a thread that has a window or message loop some thing like that... What do you think?

I was just asking for clarification. I've always referred to a "GUI thread" as one with a message loop, whereas a "worker thread" as one without a message loop. In reality, the latter can also interact with UI components but not trivially.

After you asked me the question I tried to call the function IsGUIThread() function from a thread which was created using AfxBeginThread() and CreateThread(). the behavior I found was that the IsGUIThread() function return true when called from a thread created using AfxBeginThread() where as it retured FALSE when called from a thread created using CreateThread(). after checking the MFC code, I found that When we call the AfxBeginThread the Entry point is actually _AfxThreadEntry and inside that function a SetWindowsHookEx() is called. Thats why the IsGUIThread() function returned TRUE when called from such threads. But I didnt understand why..

huh?
The reason I asked the question:
I have these objects -- with entrypoints....
They affect UI and work much better when called from a UI thread -- threads with a message queue attached.
I just wanted to put some assertions in to make sure the API's were used correctly.
I'll take a look at IsGUIThread

FYI
In VS 2008, the threads window now has a category column that shows the main thread, worker threads, UI threads, and RPC threads.

hello,
I wanted to create a new table in access through a code in VC++.
Can I use CRecordSet to create a new table in access?

You can use CDatabase for this. Also, Google for "CREATE TABLE."

When we create any dialog, when we use some controls on that dialog the implementation for that dialog is inside our MFC DLLs, also if we have some custom controls then implementation for it is in that particular DLLs, as the dialog is not external dependancy (unlike BMPs), it is inside the application itself, and the information related to that dialog is given in resource file, using Resource file information the compiler takes the corresponding resources and renders dialog accordingly. Wht you must have missed is to copy the resouce file properly. Copy it again and compile it .. Hopefully it should work then.
Thanks,
Anand.

No it is not working properly. i have tried copying it again but still the same problm is there.

Try recompiling the code again.

Paresh.
