Hi

Platform: Win32 / ATL 7.0

How should I get accelarators working in ATL dialogs? I know how to use
TranslateAccelerator for raw old fashioned WndProcs. What's the
easy/elegant way to setup dialog accelerators in ATL 7.0 / VS .NET 2003?

Regards
Mathew

Try calling IsDialogMessage() in the message loop.

If you mean a modal dialog, the only way I know of is with a hook - see
SetWindowsHookEx

Am I supposed to write my own message loop for ATL dialogs? I had imagined
there might be some appropriate pre-processing hook that I could use.

Hi Mathew,

I'm guessing youre using modeless dialogs here. A modal dialog generally
already supports accelerators.

You'll need modify your ATL module's message loop to call IsDialogMessage()
on your dialog's HWND. A generic ATL7 EXE has it's message pump implemented
in the CAtlExeModuleT::RunMessageLoop in ATLBASE.H. The implemention is
below.

void RunMessageLoop() throw()
{
MSG msg;
while (GetMessage(&msg, 0, 0, 0) > 0)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}

You'll want to reimplement this in your own module object that derived from
CAtlExeModuleT, and add a call to IsDialogMessage() when the msg.hwnd
belongs to your dialog, or is a child window belonging to your dialog. For
example:

void RunMessageLoop() throw()
{
MSG msg;
while (GetMessage(&msg, 0, 0, 0) > 0)
{
if (msg.hwnd==m_hWndDlg || IsChild(m_hWndDlg,msg.hwnd)
if (!::IsDialogMessage(m_hWndDlg,&msg))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}

Well, this won't work for obvious reasons. Make it like this:

void CMyAtlExeModule::RunMessageLoop() throw()

{
MSG msg;
while (GetMessage(&msg, 0, 0, 0) > 0)
{

if ( !(::IsWindow(m_hWnd) &&
((msg.hwnd==m_hWndDlg) || ::IsChild(m_hWndDlg,msg.hwnd)) &&
(::IsDialogMessage(m_hWndDlg,&msg))) )
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
}

m_hWndDlg should be a member of the derived class set when the
dialog is displayed and reset it when the dialog is destroyed. FWIW,
WTL has a much more elegant solution with its CMessageFilter
interface and CMessageLoop handling the filters like connection
point sinks...
