You are using CoInitializeEx, isn't it?
Define _WIN32_WINNT as following in your header file.
#define _WIN32_WINNT 0x0400

Yes,you are right.In fact I used like this:
::CoInitializeEx(NULL,COINIT_APARTMENTTHREADED);
but if I define _WIN32_WINNT as you pointed out.The problem remaian there with no change.

Be sure, this definition is first line in your precompiled header.

hi,
I am trying out a win32 application which will automate some operations (like click on Next button on a window).
My issue is a treeview. I want to get the text of a node inside the treeview. For that I am using the following code.
//**************************************
HTREEITEM hRoot = TreeView_GetRoot(hwnd);
HTREEITEM hChild;
HTREEITEM hNextItem;
if (hRoot == NULL)
{
MessageBox(NULL, "Error: Problem with tree view ", "Error", 0);
}
else
{
hChild= TreeView_GetNextItem(hwnd,hRoot,TVGN_CHILD);
hNextItem= TreeView_GetNextItem(hwnd,hChild, TVGN_NEXT);
}
//TreeView_SelectItem(hwnd,hChild); TreeView_SelectItem(hwnd,hNextItem);
char name[100];
TVITEM myItem;
myItem.mask=TVIF_TEXT|TVIF_HANDLE;
myItem.hItem=hNextItem;
myItem.pszText =name;
myItem.cchTextMax =99;
TreeView_GetItem(hwnd,&myItem);
//::SendMessage(hwnd,WM_GETTEXT,(WPARAM) 0,(LPARAM)myItem.pszText);
MessageBox(NULL, name, "Automation", 0);
//*************************************
But it is not retreiving the text. It will do upto selecting the node, But GetItem function is failing.
Pls give a solution
Thanks in advance.

How you are verifying this ?

Doesn't myItem.pszText gives you text you wanted ?

The function TreeView_GetItem() returns FALSE always and the specified string is a junk value

Try this code,
TCHAR name[100] = {0};
TVITEM myItem;
myItem.mask=TVIF_TEXT ;
myItem.hItem = hNextItem;
myItem.pszText = name;
myItem.cchTextMax = 99;

Still the function is failing and i am getting a null string in the messagebox

I wonder , why it should fail , if hNextItem is a valid handle. Can you verify that ?

No probs.
Handle is valid only.
Some experienced people told like, getting data from treeview node is difficult, compared to selecting node and all.
For that somebody has written some proxies( functions to access separate controls on windows). Soon that will be available to me.
Anyway thanks for your interest in the matter.
Take care.
Bye

How can I establish the initial directory and the filter for open file in C++ ?
Please help...
|
|
|
|

If you are talking about the CFileDialog class in MFC then here it is:
CFileDialog MyFileDlg(TRUE, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
"Text Files (*.txt;)|*.txt; |Database Files (*.mdb)|*.mdb; |All Files (*.*)|*.*||");//Filter
MyFileDlg.m_ofn.lpstrInitialDir = _T("C:\\MyDirectory"); // Initial Dir.
if (MyFileDlg.DoModal() == IDOK)
{
...
}
Hope this helps ...

I'm talking about the menu items, and I have the interface done in c# and now I want to make it in C++. I didnt succesed to make the filter files appear and the initial directory.

You'll need to be more specific as C++ knows nothing of directories or opening of files.

OpenFileDialog^ openf = gcnew OpenFileDialog();
openf->InitialDirectory = ("C:\\");
openf->Filter = "All files (*.*)|*.*|XML Files (*.xml)|*.xml|Text Files (*.txt)|*.txt";
It's something like that. I dont have errors, but it does not show me anything like filters and like initial directory.

What is the value of openf->FilterIndex?

Have you tried asking this question in the Managed C++ forum?

I can run this code without any problem. And it behaves as expected.
BTW, this question would be asked in C++/CLI forum.

I dont know exactly. I declared something else, but it didnt have to do with that function.

And you're satisifed with that resolution? Doesn't that indicate to you that you might have simply masked the problem rather than actually fixed it?
