Adding one parameter to installer

[pjn123]

I'm having problems reading parameters in nsis.

I only need a number in the parameter. The number will then replace this number in my curent code. Hope this isn't do difficult to do .

Thanks in advance.


CURRENT CODE
...
SendMessage $0 ${WM_COMMAND} 40012 0
...
The number in bold will then be replaced with the parameter.
EX:
C:\myInstaller.exe 40012
will then do the same as my current code.

I've included my source code.

Use GetParameters which you can find in the NSIS documentation under Useful Scripts.

Thanks for the help so far but I still need help getting it working. Here is the source:

!include WinMessages.nsh

Name "Alarm"
Caption "Alarm Notice"
OutFile "zzzz.exe"
Icon "..\Contrib\Graphics\Icons\llama-grey.ico"

silent by default.
; SilentInstall silent

Function CloseProgram
Exch $1
Push $0
FindWindow $0 $1
SendMessage $0 ${WM_COMMAND} 40012 0
Pop $0
Pop $1
FunctionEnd

Function .onInit
Push "Winamp v1.x"
Call CloseProgram
SetSilent silent
FunctionEnd

Function GetParameters
Push $R0
Push $R1
Push $R2
Push $R3

StrCpy $R2 1
StrLen $R3 $CMDLINE

;Check for quote or space
StrCpy $R0 $CMDLINE $R2
StrCmp $R0 '"' 0 +3
StrCpy $R1 '"'
Goto loop
StrCpy $R1 " "

loop:
IntOp $R2 $R2 + 1
StrCpy $R0 $CMDLINE 1 $R2
StrCmp $R0 $R1 get
StrCmp $R2 $R3 get
Goto loop

get:
IntOp $R2 $R2 + 1
StrCpy $R0 $CMDLINE 1 $R2

..:: How do I get the int in the parameter to the 40012.

I will run the setup like this:

"C:\zzzz.exe 40012"

If the code look funny its because I don't know much about nsis. Can you maybe correct the above code?
Hope you can help me a a
