I want to handle the ESCAPE key in certain situation; I try to catch it in PreTranslateMessage with WM_KEYUP.
Pressing ESCAPE leads always to the "cancel" result.
If I have a control named IDCANCEL, the OnClicked handler receives the control, whenever
ESACPE has been pressed, but I can not differentiate between clicking on that control
and the "true ESCAPE".
Is there a way I can separate the "escape" key from the CANCEL button and from "exit" ("X" in the system menu)?
Actually, I need it in a CEdit control.

Refer this[^].
Similarly, use VK_RETURN for enter key.

Thanks, it works with KEYDOWN

Give the button a different ID and a new handler for this ID, than it should work.
To catch up ESCAPE you need to catch the WM_KEYDOWN Event.
But it is important where the PreTranslateMessage.
Try to catch the WM_KEYDOWN event in your Dialog class.

{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
pDC->SetTextColor(RGB(20,120,220));

You must insert WM_CTLCOLORmessage to your program and for radio button its working  and again a short help
BEGIN_MESSAGE_MAP(CDialogDlg, CDialog)
ON_WM_CTLCOLOR()
END_MESSAGE_MAP()
HBRUSH CDialogDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
pDC->SetBkColor(RGB(20,120,220));
pDC->SetTextColor(RGB(255,255,220));
return hbr;
}
public:
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);

Hello everybody!
Is there any specific way to run an exe when a system wants to logoff!
Or will the system forcefully closes all active applications before logoff?
|
|
|
|
|
You can get a notification to an already running exe but i am not aware of any method to run an exe.
|
|
|
|
|
Systems send WM_QUERYENDSESSION to each application window when log off process is initiated. You can do any specific task here. Returning FALSE in response to this message causes log off operation to stop.

Hi all.
How can I get the pointer/handle to the horizontal and vertical scroll bars from list box?
I tried it using…
CListBox *pList = (CListBox *) GetDlgItem(IDC_LIST);
if( NULL == pList->GetSafeHwnd() )
return;
CScrollBar* pVertScroll = pList->GetScrollBarCtrl(SB_VERT ) ;
But it is returning NULL.
Also how I can trap the events like WM_MOUSEMOVE over scroll bar arrows?
Thanks

Did you see MSDN?
From the MSDN
This member function does not operate on scroll bars created when the WS_HSCROLL or WS_VSCROLL bits are set during the creation of a window

Hi.
Yes I saw that point mentioned in MSDN..
Thats why I asked for the method to get handle to the Scroll bars of Listbox.
Is there any way to get it?
Thanks

Can you say what do you need,excatly?
|
|
|
|
|
Sure.
In my application I have added a list box on a dialog box. This list contain so many numbers of string elements that user has to scroll too much to see all the contents.
I want to minimize the scrolling efforts of user and I want to provide auto scrolling to the list box. The elements of the list box should get scroll automatically when user movies the mouse pointer over scroll bar arrows of the list box.
For that I want to …
1. Get the pointer or handle to the Scroll bars of list control.
2. Trap the event when mouse is moved over the scroll bar arrows and kept there for some predefined time say 2 sec.
3. Scroll down or up the list with some specified speed.
How I can proceed to achieve these sub tasks?
Thanks
Sameer Thakur
