Secret Keyboard Hotkey
Hi all,
I would like to be able to hit a secret hotkey combo (e.g. CTRL+ALT+P) that would allow me to call a function which causes a message box to pop up. Though I don't want to retrieve it from the command line (see Secret Keyboard Input).
Rather setting the hotkey with WM_SETHOTKEY in the SendMessage command. When the user presses the hot key, I'd like to catch a WM_SYSCOMMAND message with wParam equal to SC_HOTKEY and lParam equal to the window's handle. Maybe anyone knows any solution.
Regards,
Rainer

I tried this to set up the hotkey (1616 is the decimal key code of CTRL+ALT+P:
SendMessage $HWNDPARENT ${WM_SETHOTKEY} 1616 0
>
The return value of WM_GETHOTKEY is the virtual-key code and modifiers for the hot key...
SendMessage $HWNDPARENT ${WM_GETHOTKEY} 0 0 $hotkey
Pop $result
MessageBox MB_OK|MB_ICONINFORMATION $hotkey
>
After pressing CTRL+ALT+P the dialog window pops up but I don't know how to call a function after pressing the hotkey or at least open a further window.

[SOLVED] Secret Keyboard Hotkey
To call a function from my script, I patched the nsDialogs plugin to catch WM_SYSCOMMAND message with wParam SC_HOTKEY. The callback routine is similar to nsDialogs:OnBack.

A small compiled version is available here:

SendMessage $HWNDPARENT ${WM_SETHOTKEY} 1616 0

-
Sets the hotkey for CTRL+ALT+P
nsDialogs::OnHotkey function_address
>
-
Sets the callback function which will be called after pressing the hotkey
The more elegant way of setting the callback is simply to insert following macro to nsDialogs.nsh.
insertmacro __NSD_DefineDialogCallback Hotkey

Usage:
function_address
