Talk:Check whether your application is running

Hello...

First of all Thanks for the plug in. I want to check my application is running or not when user runs installer.The plug in worked for me

But today i found a strange bug in this plug in.. Suppose my executable name is MyApp.exe and when I use the plugin to find MyApp.exe is running or not. It was okay. But the problem if another application MyApp Daily.exe is running the the FindProcess API suceeds.

Thanks, Harikrishnan

I found the following to be much more useful for situations like this or if the title of your window is not static:

1) Add the KillProc.dll (found here: [1]) to your nsis plug-ins folder

2) Paste the following macro in your script:

!macro CheckAppRunning APP_PROCESS_NAME
  StrCpy $0 "${APP_PROCESS_NAME}"
  DetailPrint "Searching for processes called '$0'"
  KillProc::FindProcesses
  StrCmp $1 "-1" wooops
  Goto AppRunning
 
  AppRunning:
    DetailPrint "-> Found $0 processes running"
    StrCmp $0 "0" AppNotRunning
    MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 "${APP_PROCESS_NAME} is currently running. $\n$\nDo you want to close it and continue installation?" IDYES KillApp
    DetailPrint "Installation Aborted!"
    Abort
  KillApp:
    StrCpy $0 "${APP_PROCESS_NAME}"
    DetailPrint "Killing all processes called '$0'"
    KillProc::KillProcesses
    StrCmp $1 "-1" wooops
    DetailPrint "-> Killed $0 processes, failed to kill $1 processes"
    sleep 1500
    Goto AppNotRunning
  wooops:
    DetailPrint "-> Error: Something went wrong :-("
    Abort
  AppNotRunning:
    DetailPrint "No Application Instances Found"
!macroend

3) In the OnInit function of the installer add the following code:

;Check if app is running
  !insertmacro CheckAppRunning "MyApp.exe"

4) Done!
