When you expand a node, it has to be selected or it will be selected before it expands or collaps.
So the same method TreeCtrl.GetSelectedItem(); should work inside the message handler.

But in explorer it should not be like this?
It mean I can not get the HTREEITEM at time of expanding tree item right?

Changing bitmap of CBitmapButton

11-Jul-08 0:54

You can try casting the pNMHDR into a pointer to NMTREEVIEW structure, where the structure members itemOld and itemNew will be populated with the Old and New states of the item.

Hi all,

I need to change the bitmap of the CbitmapButton on the events GetFocus, LostFocus and also in Clicked event. The problem I am facing is that, when I change the bitmap during GetFocus the bitmap is not loaded properly and when I use a breakpoint and debug the code the bitmap changed correctly. I dont know how to use it.

Also I tried to create a custom class for CBitmapButton and used it. In this I cannot set the bitmap to a particular button.

Please help me.

I think you are not using method CBitmapButton::LoadBitmaps for associating the images with the bitmap button.

m_button4.LoadBitmaps(IDB_BITMAP2,IDB_BITMAP1,IDB_BITMAP2,IDB_BITMAP2);

The above is the method I am using. For the focus events, I use like below :

void CdfdgDlg::OnBnKillfocusButton4()
{
m_button4.LoadBitmaps(IDB_BITMAP2,IDB_BITMAP1,IDB_BITMAP3,NULL);
}

void CdfdgDlg::OnBnSetfocusButton4()
{
m_button4.LoadBitmaps(IDB_BITMAP4,IDB_BITMAP5,IDB_BITMAP6,NULL);
}

The code looks fine. I assume that you have made the button property as "OwnerDraw".
It could be a problem of repainting the client area. Try calling m_button4.UpdateWindow() after calling LoadBitmaps. Ensure that the bitmaps are of correct size, color depth and fits correctly on the button. Also ensure that the method LoadBitmaps returns TRUE.

Hello Paul,

bool val=m_button4.LoadBitmapsIDB_BITMAP4,IDB_BITMAP4,IDB_BITMAP4,IDB_BITMAP4);
m_button4.SizeToContent();
m_button4.UpdateWindow();

The above is also not working. I studied about Subclassing but I dont know how to implement it. Please advice.

get date from database using vc++

10-Jul-08 23:37

With MFC:

int iItem = 5;
CString szItem;
szItem.Format(_T("%d"),iItem);
listBox.AddString(szItem);

Plain Win32:

INT iItem = 5;
TCHAR szItem[32];
_stprintf(szItem, _T("%d"), iItem);
SendMessage(hWndListBox, LB_ADDSTRING, 0, (LPARAM) szItem);

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.
