    Hi. Is there any way I can make a java applet load on a VB ActiveX control - designtime XOR Runtime?

    Thanks.
    Code:
    Dim yosef as Programmer
more.list.AddItem "Java", vbMore
yosef.AddList("VB", "C++", "Pascal", more.list)

    No it is not directly possible to load a Java applet on an Activex control. the applet needs to run in the VM which is available in the web browser. As of now I have not heard on any ActiveX that hosts a Java applet. The only way you can do this is by invoking the web browser from your application with an HTML page that loads the applet. By the way why do you want to load a Java applet from a VB application.

    Actually, you can call an applet from VB by getting the applet object ---> applet = GetObject("java:package.AppletClass") and then use it's "show" method. I tried it, it works, it's closer to what I need then invoking a browser, but it's still not it.

    What I'm doing is: I have a part of the application that must call another application, written in jave (actually, an applet). now, I want to make the applet run inside the VB application window.

    A thought: maybe I can somehow set the parent hWnd of the applet to be the hWnd of some activeX control?

    Dear yosef,
    Well I never knew you could invoke an applet using the GetObject("javaackage.AppletClass") .Well is it VJ++ ur talking about or pure Java. In pure Java as far as I know the design of an applet is such that it runs in a sandbox i.e the Virtual Machine. Virtual Machines are available in web browsers or through the appletviewer. I don't realy know how an applet can run outside the context of the VM.

    It's pure java.

    I think, though, that once you have installed a VM on your computer, VB knows how to run an applet inside the internal JVM. Anyway it works. I get the applet object then activate it's 'show' method.

    I think the Web Browser control can be used in VB to get the work done.

    there is a control at www.activex.com :: OCX to run as JavaBeans.
