stopping eSignal

[gio2003]

dear experts,

I'm trying to integrate eSignal 7.5 inside a simple Java application.
I need help about a simple problem that occours everytime I start eSignal from my java application.

These are the steps I followed:

1. Run j2cgen.exe against IESignal 1.0 library (see j2cgen.gif attachment) including all Interfaces
2. Create the java class UseHooks that implements _IHooksEvents_If
3. Running UseHooks

This is the java code:

package it.soltec.t3.ie_signal;

import com.neva.COMClassObject;
import com.neva.COMException;
import com.neva.COMHResult;
import com.neva.COMIConnectionPoint;
import com.neva.COMIConnectionPointContainer;
import com.neva.COMSafeArray;
import com.neva.COMStdDispatch;
import com.neva.GUID;

public class UseHooks implements _IHooksEvents_If{
public IHooks m_object;
private COMIConnectionPoint m_cp;
private COMStdDispatch m_dspSink;
public int m_cpCookie;
COMIConnectionPointContainer cpc;

public UseHooks() throws Exception {
createObject();
}

private void createObject() throws Exception{
m_object = new IHooks();
GUID clsid = GUID.CLSIDFromProgID("IESignal.Hooks");
m_object.CoCreateInstance(clsid,COMClassObject.LOC AL_SERVER);
cpc = new COMIConnectionPointContainer();
m_object.QueryInterface(cpc);
m_cp = cpc.FindConnectionPoint(_IHooksEvents_If.IID);
cpc.Release();
m_dspSink = _IHooksEvents.BuildDispinterfaceSink(this);
m_cpCookie = m_cp.Advise(m_dspSink);
System.out.println(m_object.GetGetAppBuildNumber() );
System.out.println(m_object.GetGetAppVersion());
System.out.println(m_object.GetGetAppTime());
}

public static void main(String[] args) {
try {
COMClassObject.CoInitialize(COMClassObject.MULTITH READED);
UseHooks me = new UseHooks();
} catch (Exception e) {
e.printStackTrace();
System.exit(0);
}
}

When I run UseHooks, eSignal starts correctly but, when I exit from eSignal, I see the winsig.exe process already active in the windows task manager.

How can I fix this problem?

Thanks in advance

best regards

Giovanni,

I'm not sure I understand the symptom of the problem. You said that eSignal starts up fine when using your application, but when you exit eSignal, you still see winsig.exe in Task Manager? Is that correct?

I actually am able to see this as well by doing the following.

1) Start VB sample app (w/ eSignal not already open)
- eSignal opens as does the sample app
2) Close eSignal via File --> Exit
3) Check Task Manager
- Winsig.exe is still present

Upon closing the sample app, winsig.exe will disappear from the Task Manager, so it seems that having an application open that is built using the Desktop API will keep winsig.exe open after it is manually closed.

Giovanni, could you describe how this impacts you?

Thanks.

Re: Reply to post 'stopping eSignal'

Yes,
eSignal starts up fine when my java application starts, but when I exit eSignal, I still see winsig.exe in Task Manager.
You say that "it seems that having an application open that is built using the Desktop API will keep winsig.exe open after it is manually closed", but even if I exit my java app, winsig.exe still runs in Task Manager.
These are 2 scenarios I tested :

SCENARIO A:
- I run myApp
- myApp starts eSignal
- I exit eSignal
- I close myApp

but eSignal is still running (I can see it from task manager)

SCENARIO B:
- I run eSignal
- I run myApp
- myApp connects to eSignal
- I exit eSignal
- I close myApp

but eSignal is still running (I can see it from task manager)

Some informations about my app:
myApp needs to have a listener to eSignal in order to get asynchronous events from eSignal (i.e. trade order)

I send you an attachment including jar and bat file for testing my app (and also java files).

I hope you can help me to solve this problem

best regards

I haven't had a chance to test your app yet, but in looking at the .jar I see no ReleaseSymbol() or ReleaseHistory(). I tested this theory using VB and removing the Release functions from the VB Sample, and Winsig.exe closed under both scenarios, but perhaps Java is different?

Try incorporating ReleaseSymbol() and/or ReleaseHistory() upon the closing of your app, and see if that solves it.
