Best way to script plugin that works together with another exe?
  Hello,

I have a header file with macro that reads cookies of Internet Explorer Protected Mode (Low). It uses an executable that runs as a low integrity user, reads the cookie and write it somewhere. Then the macro reads it and return the cookie value.

I'm looking for the best way a script writer can use this macro with minimal coding, like only !including the associated header file of the plugin.

Also, I want writers to be able to use my macro inside a Function, so I can't add a File instruction there.

I thought of somehow make nsis extract the auxiliary exe to the $PLUGINSDIR, but I don't know how.

Here is the header file. "ExecLow" is a plugin I wrote for executing as low integrity user.

macro GetIeCookieLow Answer Domain CookieName

    Push${CookieName}

   Push ${Domain}

    Call GetIeCookieLow

    Pop${Answer}

!macroend



>Function GetIeCookieLow

    Exch $R0;Domain

    Exch

    Exch $R1;CookieName

    Push$0 ;Answer

    Exch 2

    Exch

    Push $R2;Local

    

   ${GetParent} $APPDATA $R2

    StrCpy $R2 "$R2\LocalLow"

    GetTempFileName $R2 $R2

    ExecLow::ExecLow "GetIeCookieBroker.exe" "-domain=$R0 -cookieName=$R1 -answerFile='$R2'"

   ReadINIStr $0 $R2 "General" "cookie"

    

    Pop $R2

    Pop $R1

    Pop $R0

    Exch$0

FunctionEnd

GetIeCookieBroker.exe should exist somewhere on destination computer, and I don't know how to do it in the header file only.

Any suggestions?

Why not use File inside a function? You could create a function that would do all the magic and call that in your macro. Have it InitPluginsDir and then extract the executable, if it doesn't already exist, to $PLUGINSDIR.
