Have you tried just navigating through the files/folders without adding anything to the tree data structure?

Geez... Why don't you use the debugger for that purpose ? It is the purpose of such a tool and it is much more helpfull (and faster) than posting a message on a forum.
We cannot tell the problem just by what you posted (and don't post the complete code because the problem will be the same).
Start your debugger (press F5) and see where it crashes. You can look through the call stack windows to see in which function it crashes. You can also set breakpoints (F9) to step into your code to see where it crashes.

This is the think that should be done before posting your coding problem on codeproject. This helps alot...

It crashes at here:
} while (_findnext (File_handle, &file_s) == 0);

I dont know the difference between what is the SendMessage and PostMessage and Difference between SendMessage and Postmessage.

It can be said that SendMessage is Synchronous in nature and PostMessage is Asynchronous in nature.

Please google before posting a question.

SendMessage(..)
The SendMessage function sends the message to a window or windows. It calls the window procedure for the specified window and does not return until the window procedure has processed the message.
PostMessage(..)
The PostMessage function places a message in the message queue associated with the thread that created the specified window and returns without waiting for the thread to process the message.
For more information search on the following site with SendMessage:

I can give you an example to understand when use the functions:
If you want that an object (CWnd) close itself without problems, probally the best solution is Postmessage(WM_CLOSE). Elseway if in a member (of this object) function you use Sendmessage the object will be destroyed before that the function ends, and it is probable that after Sendmessage some operations will be done on the members of this object. So this is a cause of a crash.
Have a nice code day

Having problems about right clicking on an item in a tree control. The item
that is clicked on is not the right one.
If I have three items in a tree.
Here is my problem. I click on the first item with normal click. I click on
the third item with the right click mouse. In this event I had a messagebox
telling me which item is selected, and this one comes out with the first
item no mather what. I also tried to get into the OnSelchangedItemfieldtree
function - but with no luck.
How can I right click on the third one and get its name out of it? Does
anyone know?
More relaxed the person,high is his status.

For handling right click override Tree control's OnRButtonDown.
In this function HitTest with the point so that u will get the selected item and then use GetItemText to get name of the item.
void CExplorerView::OnRButtonDown(UINT nFlags, CPoint point)
{
// TODO: Add your message handler code here and/or call default
// To get selected item
HTREEITEM hTreeItem = GetTreeCtrl().HitTest(point);
GetTreeCtrl().SelectItem(hTreeItem);
CString cstrItemText = GetTreeCtrl().GetItemText(hTreeItem);
CTreeView::OnRButtonDown(nFlags, point);
}

Use MAPI to access the PST file.

Didn't you just ask this very same question barely an hour before this one? CodeProject is seen by folks from all over the world. You must give them all a chance to read, and digest, your question. Posting the same question over and over is a sure-fire recipe to irritate folks to the point they do not want to help, even if they knew how.

Hello everyone,
I need to work with C and C++ together in one application, for example, I need to call C++ methods from C method. And I have also used some namespace and other C++ features in my C++ method. So, is it possible to invoke C++ methods containing namespace (or other C++ specific features) from C?
I am using Visual Studio .Net. I am wondering how to make C and C++ work together. Are there any existing tutorials?
thanks in advance,
George

not simply. you can put C++ inside a DLL or a COM object and let C call it that way. but otherwise, no. they are two different languages and you need some kind of language-neutral interface (ie. DLL/COM) for them to be able to interact.

Thanks man,
I think even if I put C++ inside a DLL I have to make a .h file for C code to compile. Then, I can link with the DLL. Is that correct?
So, the further question is that, I have to define a .h file for C++ methods for C, I am wondering how to do that? Do you have any samples?
regards,
George

you won't be defining C++ methods, you'll be defining C functions, and exporting only C functions. the DLL can use C++ internally, but the external interfaces need to be all C. if you need to pass objects out of the C++ code, you'll need to do it using "void *" or some other trick.

Thanks for your reply!
I have two more points,
1. I think to utilize C++ methods from C, I can also build C++ files into object files and then make C modules link with those object files. Is that method ok? Why do you say I have to build C++ methods into DLL?
2. Are there any existing samples to illustrate your methods/tricks?
regards,
George
