As another poster pointed out, when you delete an item it alters the indices of all the items that follow. For example, after item 0 is deleted what used to be item 1 is now item 0. Try modifying your code as follows:

for (int n=0;n < m_List.GetItemCount(); /*Empty*/)
{
    if(m_List.GetItemState(n, LVIS_SELECTED) == LVIS_SELECTED)
    {
        m_List.DeleteItem(n);
    }
    else
    {
        ++n;
    }
}

Even better, as the other poster indicated, go backwards and the problem goes away without the need for the above complications.

I'd suggest you would delete item 3 from the list (the indices are zero-based) and insert a new item. Look at the DeleteString and InsertString methods.

It's logically correct to do either of the 2 things.

Either make the list sorted.
Or add the items in the required order.

In this particular case, you should insert "All" at index 0.

How are you interfacing to the database? What's the data type of the relevant column in the database table?

Using (for example) OLE DB with an Access table containing a Date/Time typed field, you interface via a rowset that will have a member variable of type DATE, rather than a string.

I have got three 2D images about the height of one object int three different angle of view. Now, I want to transform the three images with Rotation matrix into one global reference frame. But I don't
know how to do with the datas in the overlap area of three different angle of view's images with C/C++.

It sounds to me like you need to extrude each of the images in the plane of the image, then perform intersection operations[^] to shape the object?

Can you use a package like Blender or somehting to do that rather than writing your own? Alternatively, there are several libraries that will help you do that[^].

So please help me

I don't think you can track whether a tray icon is visible or not.

Even if you could, there are so many better ways to send messages between processes.

Look at Interprocess Communications[^] and Interprocess Synchronization[^]

Handling KeyDown even on Dialog.

Why am I not able to handle WM_KEYDOWN on a dialog? Pretranslate is the only way? Also what's the reason the event is not getting dispatched to the dialog?

Re: Handling KeyDown even on Dialog.

Stuart Dootson27-Mar-09 23:41

Probably because the control with focus is getting the messages, not the dialog.

Add your WM_KEYDOWN handler and add this PreTranslateMessage override and you should be good, so long as your dialog is modal:

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
   if (pMsg->message == WM_KEYDOWN)
      pMsg->hwnd = this->m_hWnd;

   return CDialog::PreTranslateMessage(pMsg);
}

I could rather manipulate that the key in pretranslate() itself right?

Stuart Dootson wrote:

That was my guess, Just to test that I tried deleting all the controls on the dialog. Just a plain dialog but still it's not getting the event. What could be the reason here?
