Reversing UnRegisterFunc1 KeyLocking
|
From: werD on 16 Mar 2007 01:18 Im running into a problem with a locking app im working on. Im using UnregisterFunc1 along with RegisterHotkey from coredll.dll to disable softkeys and phone buttons and such. my problem is that when i use them to lock and then unlock ie close app the buttons still no longer work until the device goes through a soft reset. Is there a way that I can get the handle off the apps needed and set them back to their original hotkeys or a function to set them back to what they were last laoded as, or is there some other way to achieve the lock/unlock abilities beyond these? For the hardware keys im using SHSetAppKeyWndAssoc from aygshell.dll which give the expected results but im stil unable to stop the windows key from makig it where a user might accidentally press something in there pocket. here's where i disable the soft key. Does anyone know how i can "undo" this? Public Enum KeyModifiers None = 0 Alt = 1 Control = 2 Shift = 4 Windows = 8 End Enum Public Enum vKeys As Byte 'Hardware Keys 1-6 HardwareKey1 = 193 HardwareKey2 = 194 HardwareKey3 = 195 HardwareKey4 = 196 HardwareKey5 = 197 hardwarekey6 = 198 'SoftKeys L/R SoftKeyLeft = 112 SoftKeyRight = 113 'Phone G/R PhoneOpen = 114 PhoneClose = 115 End Enum <DllImport("coredll.dll", SetLastError:=True)> _ Public Shared Function RegisterHotKey(ByVal Handle As IntPtr, ByVal id As Integer, ByVal Modifiers As UInteger, ByVal key As UInteger) As Boolean End Function <DllImport("coredll.dll")> _ Public Shared Function UnregisterFunc1(ByVal modifiers As KeyModifiers, ByVal keyID As Integer) As Boolean End Function UnregisterFunc1(KeyModifiers.None, vKeys.SoftKeyLeft) 'I dont think this is running bcause a press of the no unregistered Softkey does noting even after the app quits RegisterHotKey(Me.Handle, 0, KeyModifiers.None, vKeys.SoftKeyLeft) Id appreciate any insight or experience on this one? Thanks DrewG
From: werD on 16 Mar 2007 03:18 Ive been looking into different ways of reinstating the functionality and thought that perhaps i would need to stop the process "cprog.exe" but i downloaded a task manager hoping to find that the handle or process id was persistant and went to close the process as a test and immediately lost phone service!(that would suck if I got a call and went to unlock and answer but dropped instead) So it looks like the only way I can do this is to get RegisterHotKey to work properly for that I at least need to know how to dynamically get the handle for cprog.exe Can anyone suggest a direction to go in to get this acomplished or let me know why my buttons lose all functionality(ie registerhotkey isnt registering or perhaps needs to be flushed?) should i perhaps look into replacing the phone launch program with a launcher through a registry edit that would call the app or hang up(that is if i can get registerhotkey working like it supposed to)? i dont think this would be as easily manageable across devices though its not at all ruled out at the moment.

From: Henryk Birecki on 19 Mar 2007 16:30 Does it happen on all devices or a specific one? I have not really had any troubles with hardware keys using the (Un)RegisterHotkey or SHSetKeyAssoc (not sure exactly at the moment if this is the correct name) set of API except for hx2100 series of iPaqs on which keys seem to freeze.

From: werD on 19 Mar 2007 17:03 Hello Thank you for your response. I have been able to replicate this behavior with the emulator and with my Device (an HTC wizrd). Generally Im using SHSetAppKeyWndAssoc for the hardware keys with good response with it. But, unfortunately, I was unable to get the phone buttons to follow this pattern( i.e. the phone on and phone off buttons still brought up the phone menu even if the association was changed) so I resorted to unregistering them both with api call UnregisterFunc1. But then the behavior changes.. ( i.e. when i close the app the hardware buttons return to normal but the phone buttons still dontfunctin at all). I have found that if I kill the process "cprog.exe" and restart the associations(only phone not softkey) are restored but the phone drops signal when the process is killed so this is not a viable solution, but it does lead me to believe that cprog.exe calls a (possibly undocumented)api call that re registers the button with its default association. Does this make sense? Have you ever had to deal with anything like this before or do you possibly know of an api call that reproduce this effect(re registering phone buttons)? Thank you for your input, it is greatly appreciated. "Henryk Birecki" wrote: > Does it happen on all devices or a specific one?
