Functions and .rul

[retzcat]

I've created a .rul file (pure installscript installer) which contains 4 functions all involving NT service piece, like finding if a service is running. I've included the .rul name in my main setup.rul and am trying to use one of the functions in the setup.rul file. I keep getting an error that the function is undefined. Not sure what I'm missing...

The .ruls are

Setup.rul
StopService.rul
uninstall.rul

In Setup.rul
#include "StopService.rul"
#include "uninstall.rul"

Trying to call a function:

function StopDerby()
string szServiceName,nvServiceState;
NUMBER nResult;
begin
szServiceName = "sl-derby.exe";

ServiceConnections(szServiceName); //From StopService.rul

end;

Error is Undefined Identifier on ServiceConnections

Any ideas?

Thanks

As a sanity check, are those #include lines at the top of setup.rul?

Where are the functions prototyped? They need to be declared before they are called in your code.

Hello,

Esiemiat is correct. Where are your prototypes? The file arrangement and code should look something like this.

In StopService.rul

///////////////////////////////////////////////////////////////////////////////
// StopService.rul                                                           //
///////////////////////////////////////////////////////////////////////////////
// Prototype Area                    //
///////////////////////////////////////
prototype StopDerby();

///////////////////////////////////////////////////////////////////////////////
// StopDerby                                                                 //
///////////////////////////////////////////////////////////////////////////////
function StopDerby()
    string szServiceName,nvServiceState;
    NUMBER nResult;
begin
    szServiceName = "sl-derby.exe";

    ServiceConnections(szServiceName); //From StopService.rul
end;

In Setup.rul

#include "StopService.rul"
#include "uninstall.rul"

function OnFirstUIBefore()
begin
    
    StopDerby();

end;
