1. Register shortcut keys

In the initialization function, such as OnInitDialog () register the shortcut key, the code is as follows:

#define HOTKEYID1 200

BOOL Cdlgcloseprosetup::oninitdialog ()

{

CDialog::OnInitDialog ();

:: RegisterHotKey (M_hwnd, HotKeyID1, NULL, vk_home);

return TRUE;

}

RegisterHotKey () The first parameter is a handle, the second is the accelerator ID number, can be arbitrarily defined, the third is a control key, if not required to be set to NULL, the fourth is a letter or a number, the same does not need to be set to null.

2. Add the following message:

3. Write in the Onhotkey function

void Cjseditdlg::onhotkey (UINT Nhotkeyid, uint nKey1, uint nKey2)
{
TODO: Add Message Handler code and/or call default values here
if (Nhotkeyid = = HotKeyID1)
{
Onbnclickedbtnkill ();

}

Cdialog::onhotkey (Nhotkeyid, NKey1, NKey2);
}

4. Add a WM_CLOSE message to write in the OnClose function

void Cjseditdlg::onclose ()
{
TODO: Add Message Handler code and/or call default values here
Unregisterhotkey (GetSafeHwnd (), HotKeyID1);
Cdialog::onclose ();
}
