Title: ListView control : how to detect Ctrl-A shortcut to select all the items
Post by: Jean-Pierre Leroy on March 28, 2018, 08:58:05 AM

I have a listview control and I would like to detect the Ctrl-A shortcut to select all the items.

Any ideas how to do that ?

Thanks,
Jean-Pierre

check WM_NOTIFY code

Code: [Select]

void OnNotify(HWND hWnd, WPARAM wParam, LPARAM lParam)
{
if (wParam == 4001) { // Listview Id
if (((NMHDR*)lParam)->code == LVN_KEYDOWN) {
if (((LPNMLVKEYDOWN)lParam)->wVKey == VK_A) {
SHORT nState = GetKeyState(VK_CONTROL);
if (nState & 0x80) {
SetWindowText(hWnd, "Ctrl-A");
}
}
}
}
}
