There are many issuies when you're useing multithreading regarding of your question about simultaneous access to data and whether or not you may call SuspendThread(). You should read at least MSDN topics about CriticalSection usage, about functions WaitForSingleObject/WaitForMultipleObjects and some related topics. Good luck :)

You can directly dequeued all of messages by function GetMessage. You should call PeekMessage and GetMessage in iteration till queue will be empty IMHO. But may be some backside will occur, I don't know

I need to select first item in virtual list control (CListCtrl with LVS_OWNERDRAW style set). Is any notification handler exists that notifies then CListCtrl finished collect data? Sorry, if I confuse you with explanation Thanks in advance

Pass HWND of MainFrame through thread parameters and then create CWnd object by CWnd::FromHandle(HWND) function in workeer thread

Thanks a lot :) I'll be searching more carefully in future. Shit, why did I can't find it myself :) It's really what I need.

All threads in MFC has own CWnd-HWND map and it don't initialize while you create new thread due to perfomance reason. A common solution is to put HWND in thread-parameters and in child thread should construct CWnd by means CWnd::FromHandle function. Good luck

You're about right :) It's no so hard, but I thought that building new thread, organizing some kind of inter-thread sinchronization is too big to doing such small task. Besides really I have had separate thread that perform that task already. But it's so bulky :( That why I decided to ask simplier solution.

Thanks but I can't understand how can I implement it in MFC way. Would you mind show me the way :) My task is first ie I want to operate own data Thanks in advance

IMHO it handles WM_SIZE message and resize control accordingly

I have standart generated by ClassWizard SDI MFC-app. I want that some operation invoked by user that may be performed a while was displayed like dialog with progress bar and "Cancel" button. And while it's displaying, operation should performs, progress bar should displays appropriate value and so on till operation has been completed or user has clicked "Cancel" What's the easiest way to implement that. After searching through MSDN some implementation approach has appeared but it's so difficult. Thanks in advance.

I see :) But I didn't find any answer to my question there. I need not WinNT with GUI interface, in contrary I need TWO processes. First one is a WinNT service and second one is a GUI program to manage first. Also this interacting should be double sided in order to service was be able to notify GUI program about its state. Sorry if I can mistake but I've really find not answer in topic being advised. Sorry again if I am silly :) At such case give me exact link please. Thanks (and sorry) in advance ;)

?:confused:

Thanks a lot. It really gave me a good idea. But look at this code: void CLeftView::OnRclick(NMHDR* pNMHDR, LRESULT* pResult) { unsigned char *p = (unsigned char*) pNMHDR; p -= 4; // !!!!!!!!!!!!! NMTREEVIEW *z = (NMTREEVIEW*) p; CPoint ptXY = z->ptDrag; } It works too!!! ptXY after all of these manipulations is a real mouse coordinates X|
