I am not using windows forms. I am using MFC thanks Vicky

I want to draw an item ( a particular one) in Mousemove of an owner drawn list box. How do i the dc and for that item ( bounds). - thanks Vicky

I wanted information about the controls inside the tab which displays the layers and thumbnails.

Which version of visual C++ are you using? Try deleting the .NCB file and relaunching.

I wanted to implement a tree like structure similar to the layers control in Photoshop. I am unable to decide which control should I subclass and use for this purpose. Tree control i dont think will be useful for such a task. How about subclassing a Listbox and drawing all the things on my own. Comments please. Vicky

Yes i am using it get the state of the ALT key but the point is I want to change my cursor as soon as the user presses the ALT key so for that i would require an event being fired or Currently i am using a timer which uses GetAsyncKeyState() to get the state and then i change the app cursor. Thanks

It works only if i press a key followed by ALT. I want an event which fires when i press just the ALT key .

How can I detect when the ALT key is pressed and no other key is pressed? I wanted to change my cursor when the ALT is pressed. So i wanted to know which message is sent in this case. Thanks

Thanks I will try that but i am open to any more suggestions

What are the color values of the base, Can Anybody give me the info. Thanks, Vikash

I want to know some good book on the Visual C++ .Net 2003 IDE which explains all the changes and how to use the new features in the IDE. Thanks

you can try using The FindFirstChangeNotification(easier) or SHChangeNotify function.

The thread must finish execution on its own based on some condition. Use WaitForSingleObject or WaitForMultipleObjects if you got wait for some signal and u can also give time. There are other methods also that can be used to stop execution like signalling a flag etc.

I am setting the text using SetItemText and not label edit. I want to know if any event triggers whenever a SetItemText is done on a Tree Item.

Whenever the text of a tree item changes how can i know it. Which notificacation is sent. The text is being changed programmatically

No, You have to convert it to a string and then print it. You can use CString Format method or wsprintf or sprintf and create the formatted string then use it to display the msg.

Thank you very much Mike works very well. I have read your articles on this site and find them very good. I admire you. Thanks once again. But one more question I am using a ActiveX control and allocating it on the heap. I create it by calling Create(). When i free the memory the GDI object handles and USER object shown in process viewer decreases but not to the count it was before I do the creation operation If i try to call DestroyWindow() it gives assertion error. Why is it so? What should i do to decrease the GDI object and USER object count as it increases with usage time.

;PHello all, I am using CTreeCtrl and when creating items and I am storing a LPSTR into the lParam of the TVITEM struct. When I need to clear the contents I need to free the memory allocated but to get the pointers I need to traverse all items in the tree ctrl but could not find any easy way to do it. Can anyone guide me? Will the method that i write be recursive or can i write a non recursive function? I need to get each item data in the tree and then free the memory and then I can call DeleteAllItems on the tree. Thank you Memory Leaks are very dangerous.;P

Thank you. But suppose the process is spread over several loops then how do i do it.

How can we set the progress bar for a situation where we dont know how much time the operation takes like Windows displays the progress when copying/Moving a file it varies depending on read data speed. Is there any estimation method. I saw one article on this site called Timed Progress but the code is not at all documented so i cannot understand what it is doing? Can anyone suggest something? Vikash
