I'm trying to set up a fairly sophisticated user interface from an applet running under Internet Explorer 5+ (without the java plugin).
javax.swing.* appears to be unavailable so I've been working with
com.ms.ui.*
Trouble is I've found no documentation for these classes beyond the bare definitions I get from J++ and few examples. I'm working largely by trial and error.
I'd like to put a file and directory selection window on the applet form (rather than using the FileDialog). (Yes, it's a signed applet).
Has anyone located any documentation for this stuff? This is an extremely frustrating way to work.

The MSDN library that you can buy, or it comes with Visual Studio has massive amounts of documentation. It isn't free, however. It may be worth it if it allows you to do it much faster. Try Microsoft Developer Network to see if there is anything on there

Hello,
I am very new to java.
I want to call a C-dll function from my java code and I don't know how. Can you please help?
Thanks.

There are facilities for this kind of thing in the MS version of the java engine. It's documented on the microsoft java site. Basically microsoft have put in some naughty java extensions for this purpose.
You do things like
<br />
<br />
static native int MessageBox(int hwndOwner, String text, String title, int style);<br />
(This must be in a class definition, of course).
I rather doubt there are any facilities to do this kind of thing in the Sun java engine. It's too machine dependant.

Yes, there is. It's called Java Native Interface.

That doesn't look like it would allow you to access an existing DLL though. Only one specially written for this purpose. Of course you could write an interface from there to a standard DLL.
|
|

That's right.
I found JNI but it sounds like it is very slow.
And you can't use existing dll.
1.You write the native methods declaration in a java class
2.Then you compile the java class (javac)
3.Generate a header file from this class using javah -jni ...
4.include this header in you dll project and provide and implementation for the generated header functions.
5.Rebuild your dll
From this point, you can use the dll via the java class methods we wrote at step 1.
I tried using JNI. It works because I could change the source of the dll and I wanted to use. But it is surprisingly slow. Now I am looking forward to using sockets.
Thank you.

I'm currently developing an app that invokes a JVM from C++. The app then calls a bunch of java methods. Unfortunately, somewhere down the line, an exception has occurred in java. I'm using the env->ExceptionDescribe() function, but it only outputs to stderr (of this i'm not sure). Unfortnately, I'm running the C++ directly from Matlab (Via a mex function interface), so there is no console window in which to view exception message. Is there anyway to intercept/view the exception message that JNI so thoughtfully prints out to stderr?

I'm looking for a Java compiler. To improve performance of a Java based application I would like to compile the code in machine binary code - not in bytecode. I've been looking around for that compiler on the Web but couldn't find any clue.
There used to be a Java compiler called SuperCede and another with Visual Cafe but they don't seem to be maintained anymore.
So is there still a serious Java compiler somewhere ? ...and does it really improve the speed of a Java application ?
I know that this is not in the good way to deal with Java which is natively a multi-platform based language, but Windows is the only platform for my clients  )

There's GCJ, but it's not (yet) ported to Windows.
|
|
|
|
|
The GNU products are always good quality ones. It's obviously a challenge to compile the entire Java class libraries. I'll closely follow GCJ.
Thanks

Go to www.java.sun.com
Look for javaplugin or /*something*/ you have to link to their plugin!

Hi.
I'm creating a SMS-mobile sollution and the gateway that we use require us
to write files to an Outqueue for SMS-messages to be sent. The files are
simple text-files. The problem I'm dealing with is that the gateway require
our application to "lock" the file while writing to it, that is, no other
application can have file-permissions on our file. When the file containing
the SMS-message is written, the file-permissions need to change to "full
control" to allow other applications (the Gateway) to access it and delete
it once the message is sent.
Does anyone know how to solve this, or have a link to any useful information
?
Any help would be greatly appreciated !
Best Regards

I'm an absolute Java beginner so please forgive me 
I've got an applet (written in VisualCafe V4.5) that works fine in an applet viewer, but when I try to view it in a web page (IE6 and NS6.1) all I get is a gray box where the applet should be.
I assume the applet is correct as it's stage two of the tutorial that comes with VisualCafe Expert Edition. I'm also sure the class path name is correct.
The WebGain newsgroups hardly have any posting going on at all, and I know this may be a long shot, but I thought I'd ask this here.  Thanks ever so much to anyone that can help.
