Ok, so what is the error that appeared? I suspect it has something to do with obj not being associated with an actual control, thus DeleteAllItems() and InsertItem() would fail.

In your previous code snippet, the comment indicated that obj was a CTreeCtrl. It also appeared to be a local variable rather than a member variable. What does the DoDataExchange() method look like?

When you take your car to the mechanic and ask him to take a look at the engine, it makes no sense to then show him the flat tire, ergo he starts the task of fixing the flat rather than the engine.

I assume you have a view with a tree control in the left pane and a list control in the right pane. Correct? Exactly what data is it that you want to share between the two controls?

ya u alright
in the left pane is the TreeCtrl and ListVtrl at right
so at TreeCtrl Names of poeple came ffrom the data base
and when i clicked on the Item(name of the person) his/her information must appear at the ListCtrl after making a query from the database

so how could solve the problem that appeared when i insert new data in the ListCtrl

I assume that the tree control is populated from a data structure (e.g., array, list) of some sort that holds all of the details. For each node that is added to the tree control, call SetItemData() with a pointer to one of the items in the aforementioned data structure. When an item is selected in the tree control, call GetItemData() to get access to the data. Now clear the contents of the list control and populate it with the data that was obtained from the call to GetItemData(). When the tree control needs to communicate with the list control, use PostMessage().

Error C2011 VS 2003

I get the error:-

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\wchar.h(437): error C2011: '_stat' : 'struct' type redefinition.

I have checked all my header files to see if any included more than once.

The only way I can get the program built is to comment out the following lines in this (Visual Studio wchar.h) file!

#if     !__STDC__<br />
/* Non-ANSI names for compatibility */<br />
// struct stat {<br />
//        _dev_t st_dev;<br />
//        _ino_t st_ino;<br />
//        unsigned short st_mode;<br />
//        short st_nlink;<br />
//        short st_uid;<br />
//        short st_gid;<br />
//        _dev_t st_rdev;<br />
//        _off_t st_size;<br />
//        time_t st_atime;<br />
//        time_t st_mtime;<br />
//        time_t st_ctime;<br />
//        };<br />
//<br />
#endif  /* __STDC__ */<br />

I am worried that this will cause me problems later.

Are they anything I can do to overcome this problem?

Cheers,

the syntax is not correct...

replace with #if !defined(__STDC__)
or with #ifndef __STDC__

Both options produced the same error (C2011) when comments removed.

This is a Microsoft file, so should we be modifing it?

wow, absolutely not !!!

i thought it was one of your when you told you commented on... never do this !!!

however, don't you create a struct in your files that is in fact already defined in the library ? if so, change your structure identifier...

I have searched my project to ensure that no types/structures have the name stat.

None present.

Still confused, but thanks for your help.

PS Still have the Visual Studo file with my commented out section.
