Be that as it may (I can neither confirm nor deny), the product, at least the 1993 version, is still licensed to them and is still in use by Microsoft Office XP.

This is a (very old) link I have lying around.

http://www.subsystems.com/stw.htm[^]

How old? It mentions OS/2 OMG | :OMG:

But then it goes on to mention a .NET version... Confused | :confused:

On the plus side, you do get the source code Big Grin | :-D

Also, there's probably loads at www.componentsource.com[^].

CTreeCtrl Right Click question...

Maximilien7-Sep-04 5:04

I handle the right click in a CTreeCtrl with

ON_NOTIFY( NM_RCLICK, IDC_TREE1, OnTreeRclick )

and

void CTestTreeDlg::OnTreeRclick( NMHDR* pNMHDR, LRESULT* pResult )
{
 NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
 HTREEITEM hSelItem = pNMTreeView->itemNew.hItem;
}

When I right click on the tree background, not on a leaf or node, the hSelItem is not valid, and is not a "simple" value like NULL or zero.

Is there a way to check to see if the HTREEITEM item is valid ?

I tried the following to see if I can get the item based on the hitem the notification message gave back, it could "work" but it gives a "First-chance exception" when passing a bad hitem.

TVITEM item;
TCHAR szText[1024];
item.hItem = hSelItem;
item.mask = TVIF_TEXT | TVIF_HANDLE;
item.pszText = szText;
item.cchTextMax = 1024;
BOOL bWorked = m_Tree->GetItem(&item);

Thanks.

Max.

I would use:

void CTestTreeDlg::OnTreeRclick( NMHDR* pNMHDR, LRESULT* pResult )
{ 
  CPoint point(GetMessagePos());
  m_tree.ScreenToClient(&point);
  <br>
  HTREEITEM hi=m_tree.HitTest(point);
  <br>
  if (hi)
  {
    // ...
  }
  // ...
}

where m_tree is the CTreeCtrl member associated with your control.

Maybe not the best method but it works.

It seems like the lesser evil ...

Locked Computer and Hooking

Hi,

I'm using WH_MOUSE and WH_KEYBOARD hooks to sense user movement just like a screensaver. The screensaver prevents the hook messages from reaching the program. Therefore I disable the screensaver when I enable hooking.

Now I've realized that if the user locks the computer manually - by pressing CTRL+ALT+DEL and afterwards the "Lock Computer" button, then the hook messages never reach the program.

Is there a way to let the hook messages pass beyond the logon screen and reach my running program?

Thanks in advance...

inject your code into the process that is showing the user screen and enable hooks from it

Get URL via Drag'n'Drop

Hi there,
I want a dialog-based MFC application, that receives URLs from Internet Explorer via Drag'n'Drop.
My Dialog consists of Listboxes, Edit-fields, buttons and so on. I want my Internet-Explorer to show a html-page. When I drag this page to my dialog, I want to process this URL to display the parts of the URL in different controls.

I tried a simple FileManager-Drop Operation, but Internet Explorer does not provide URLs via this Mechanism. All the OLE-examples show, how to drag items from a listbox into another listbox.

How can I receive a Drop from Internet-Explorer?

How to know which module has handles in a process

Hello,

Now I have been testing a aplication program which is implimented
by Win32(VC++) and Pro*C.

What I am comfused is that the count of the application's handles
which is displayed on TaskManager is incremented only, never decremented.
The application should be used for 24 hours everyday,
so I think this is a serious problem.

I have been triying to check my code,
especially where kernel objects is created and the handle should be closed,
but I haven't found what is wrong.

I guess that I can get some hints if I can know which module has handles
in the application process.

Cay anybody Know about it?
or what I should do anything else generally?

regards.

You could write the program as a service so that it'd run under the SYSTEM account and then you couldn't kill it without admin privillages.

CSplitterWnd question...

Hi There,

Does anybody know if there is a way that you can prevent a
CSplitterWnd from resizing? For example if user's mouse is on
the CSplitterWnd border, the icon should not change and the user
should not be able to make the window smaller or bigger.

Second question, if you have a couple of nested CSplitterWnd's,
how can you show and hide a specific CSplitterWnd?

I would appreciate it very much if any one could help me
on these questions.

Thanks
Gerhard
