What I need this for is a tray icon! Try clicking once on the windows messenger tray-icon: A menu pops up! Try double clicking: The application shows! Messenger obviously knows when I double click and when I single click, and it isn't just handling DBLCLK, because then the menu would popup the first time you clicked.
When you right click the icon, the menu appears right away. When you left click, then menu doesn't appear until a second later. So I was guessing that they wait and see if a WM_LBUTTONDBLCLK is coming.

Hi, i need a way to communicate between my app which is written in C++ and Java. The problem is, the application that runs the java code is not mine and it just runs the java code in a safe environment. This poses some security restrictions such as, i can't open any sockets, and seeings that was the obvious way to me to make them communicate, i don't know what to try next. Are there any facilities in Java to make communication with another windows application easier?
Thanks in advance for any responses.

What do you exactely want to do upon the java application?
Wouldn't signal sends work ?

What exactly are signal sends? Never heard of them..

I'm going to pretend to be an expert on this because I just hooked up a browser-based Java application to a complex C++ library using JNI.
To get meaningful communication between the Java applet and your C++ application, you are probably going to need to remove the security restrictions on the applet so it runs outside the browser's sandbox. You can do this by signing the applet with a cryptographic signature, or by running the Java code as an application instead of an applet. Once you do this, the Java app and your C++ app can communicate by sockets, or writing files to the local filesystem, or you could use JNI (or COM if the applet is written for the Microsoft VM) and package your C++ app as a DLL that the Java applet can call.
If you can't or don't want to change the security restrictions on the Java applet, pretty much the only way to get it to communicate is to have both it and your C++ app talk to the same server on the applet's host (I suppose you could also send Windows messages to the applet's window, but that's a really limited form of communication). Applets are allowed to open a socket, but only back to a server on the host from which they were downloaded. Hosting the applet on your local machine might work for you as well.

Well the problem is that the java code is not running in a browser and its not an applet, its just.. scripts running through JNI already by another application, so i can write the scripts, but not change the application. So i want to communicate with the scripts.

If code you don't control is putting the Java code in a restricted sandbox, there isn't a lot you can do (that's what the sandbox features is for, after all).
Do you know the details of the sandbox restrictions? Do you get a SecurityException when you try to connect to a local socket from the Java?
|
|
|
|

Yes thats exactly how it is. But when i try to make a socket, i just get an error, not an exception i think, the code is basically like this:
try
{
ds = new Socket(InetAddress.getByName("localhost"),port);
}
catch(UnknownHostException uhe)
{}
catch(IOException ie)
{}
catch(Error e)
{
CodexConsole.Print(0,1,"Error");
}
And i always get the error. I looked at the definition of JNI_CreateJavaVM and there's like three parameters u pass right? Well i might be able to "crack" them out of the java container application if i know what to change, but i'm not sure.. Would that work? if i could somehow lift the restrictions?
Thanks for your help.

The restrictions aren't put in when the VM is started, but sometime later with a call to System.setSecurityManager

In my code, I have a menu to restart a service. Previously, I was calling ControlService(hService, SERVICE_CONTROL_STOP, &ServiceStatus) to stop it, and then StartService(hService, 0, 0) to start it. However, ocaasionally, this does not work. Putting a sleep(100) between these two events seems to fix it. However, I cannot guarantee this solution on all machines. Does anyone know how microsoft implements their restart button in the Services Control Panel?

tried using EnumServicesStatus() ?

Thanks. Would I have to call this in a while loop and keep trying to start this when it's not yet started? How long would I wait? I'm trying to see if anyone knows how Microsoft does it and what their timeout value is.

I noticed in the project settings that you can set the stack size. I think it was system under the linker tab inside the project settings. What does this mean. Is it the initial stack size for main or is it the default setting for any new threads created? What should the values be? I also saw something like commit stack? What's this? Thanks.

What does what mean? Are you saying that the option to set the stack size should be elsewhere?
Anonymous wrote:

1MB is the default, and is satisfactory is most instances.

Per the docs:
Provides a space for you to specify the amount, in bytes, of physical memory to allocate from the reserve memory.

hi,
I am in a gr8 trouble. I am making a client server application using ASync sockets with oracle as backend. Every thing is working fine but the problem is with closing the connection after it's use completes. i.e. when for the first time client connects to the server he is able to log in and send the data but after that is any client tries to log in then server gives the Assssertion failure error in line 177 winsock on ignoring the error the client works fine but if this happens server cannot log in the clients automatically. if there is a way to ignore this failuer or what i feel abt error is that once the socket is closed and after that if some body tries to give it gives a invaled socket error this was found out when i tried to debug the error. tell me what i can do to solve the problem. can this be due to the single m_sConnection socket i have used that when closed closes everything but there is another socket cvariacle ie m_sListenSocket that i have iused to accept connections ie m_sListensocket.accept(m_sconnectionsocket).
help me to understnd it

Has anyone come across this before. Let say you create two threads with the create thread function. You specify 1 gig (I know you would never do this) for the stack parameter for each thread. Now you try to create a third thread. The stack value is let's say 10 MB. The function will not work. It won't create the third thread. This problem seems to happen on different combinations. Let's say you make 200 threads with a stack value of 100 MB each, then you add one more thread; this thread will not create.

No, and I can't imagine anyone would under most circumstances.
You are encroaching on the 2GB limit. If you were using an OS that supported it, the /3GB switch would possibly get you access to a larger stack.
