LockedList plug-in

[mj_blue]

Hi, I am making an enhancement to our installer to change the horrible "MCI-Command Handling Window" holding open an activex control to be a more sensible message but I can't get the AddCustom work.

I have tried using the example LockedListCustom.nsi and this builds but when I say 'Yes' to the question is myapp running it never show sin the lockedlist window. I get the same behaviour in my own installer.

Details:

lockedlist V2.0
OS: XP SP3
NSIS: 2.46

code:


Function Isocxlocked

   LockedList::IsFileLocked $INSTDIR\axagp.ocx

   Pop $R1

   ${If} $R1 == true

    MessageBox MB_OK|MB_ICONINFORMATION `$INSTDIR\axagp.ocx IS locked!!??`

   ${Else}

    MessageBox MB_OK|MB_ICONINFORMATION `$INSTDIR\axagp.ocx is not locked.`

   ${EndIf}

Push true



FunctionEnd



Function MyAppCallback

  Pop $R0



  ; Message box instead of actual logical test...

  ${If} ${Cmd} `MessageBox MB_YESNO|MB_ICONQUESTION 'Is $R0 running?' IDYES`

    Push true

  ${Else}

    Push false

  ${EndIf}



FunctionEnd



Function LockedListShow

  !insertmacro MUI_HEADER_TEXT `List of open Browsers with myapp in Use` ``

  GetFunctionAddress $R1 Isocxlocked

  LockedList::AddCustom /icon $INSTDIR\antixgpb.exe 'Internet Explorer' iexplore.exe $R1

  GetFunctionAddress $R0 MyAppCallback

    LockedList::AddCustom /icon $PLUGINSDIR\myapp.ico `My App v1.0` myapp.exe $R0

  LockedList::Dialog /searching "Searching for Browsers in use" /noprograms "No Browsers have Game Player in use" /autoclose

FunctionEnd

I have this running twice in the code above, once detecting if the file is in use (and currently forcing a true return) and once is extracted straight from the demo app.

Any help with how to get this working appreciated.

Thanks
