Hi,
I need to capture the mouse click event to determine where the click is on the shape, so as to make the response action, I set the SetWindowsHookEx, the hook code from Global Low Level Key Board and Mouse Hook
private IntPtr SetHook(MouseHookHandler proc)
{
using (ProcessModule module = Process.GetCurrentProcess().MainModule)
return SetWindowsHookEx(WH_MOUSE_LL, proc, GetModuleHandle(module.ModuleName), 0);
}
i setup the hook in AddinModule's InitializeComponent()
private void InitializeComponent()
{
this.components = new System.ComponentModel.Container();
....
mouseHook = new MouseHook();
mouseHook.LeftButtonDown += new MouseHook.MouseHookCallback(mouseHook_MouseDown);
mouseHook.Install();
....
}
I found a strange phenomenon, not every time I open PowerPoint the hook program will take effect, sometimes it will not capture any mouse events, I don't know where the problem is.
I saw one of your articles about the hooking process Add-In Express and Windows Hook I don't know if it is related to this |

Hello Chris,
Hooks are outside of the scope of our support services. In a COM add-in, you can use the Selection object to find the control selected.
