Close Running Application
i remember the FindWindow command in NSIS 1.4x could detect if a software was running during the installation-process and close it.

now that the commands changed, i'm in need of help.

i want my setup to

1) detect if winamp is running and force the user to close it

or

2) close winamp without asking

if you can help me, please paste the syntax. the makensis.html wasnt a big help for me!

thx in advance,

kb

This is from functions.htm in the nsis distro:


CloseWinamp

  Push$0

  loop:

   FindWindow $0 "Winamp v1.x"

   IntCmp $0 0 done

     SendMessage$0 16 0 0

     Sleep 100

     Goto loop

  done:

 Pop $0

FunctionEnd

i remember i tried this before. nothing happening. reading the makensis.html it should be possible with FindWindow/SendMessage, but i have no clue how that works. this function does nothing, but thanks anyhow for the quick reply!

I just ran it and it closed winamp just like it should. Are you calling the function?

This will not work for the current BETA of Winamp. If you want to close a BETA version simply replace

FindWindow*$0*"Winamp*v1.x"

with

FindWindow $0 "STUDIO"

Excuse my ignorance on this topic, but how do you find out the name of the Window you want to close if you did not write the application you are trying to close?

Carlos,
there is a tool called Spy++ that ships with Visual Studio. With this tool you could identify the window class or window handle of every open window.
There are similar tools called Window Finder (which ships with source code) and WinSpy.

Kichik uploaded the Spy program from the platform SDK at this thread.

kill task
is there an other way to close apps like the above one
i mean a command like kill (killtask ...)"exename"
is more simplier than write everytime a function like the findwindow...
is there a way to implement this command in the next releases of nsis

sorry for my bad english:confused:

Just make a function to do that an always pass in "exename" in one of thhe registers. Name the function "killtask" if you want, then just Call killtask

Push the class name of the application before calling it, then the closeapplication will close it.

In case of MySQL, you can NOT simply kill the daemon. If you do that, you will probably loose database consitency. Instead, simply run the mysqladmin commandline-tool:

C:\mysql\bin\mysqladmin shutdown

This terminates the server gracefully.

From within your script, this would be:


stopMySQL

  ExecWait "C:\\mysql\\bin\\mysqladmin shutdown"

>FunctionEnd 

>

Note:
Depending on your setup, this probably needs to specify a database admin-user and his password on the commandline.
See mysql docs...

A question:
Why do you want to shutdown the DB-server?
Nearly anything can be done without shutting down MySQL.
