FSX Support of FS2004 FSUIPC SDK ( Java )

[holtrk85]

I am currently using the FS2004 FSUIPC SDK for Java to support a client's application. At some point in the future, the client may want to migrate to FSX. The FSX documentation that I have read leads me to believe that lagacy FSUIPC based applications will work with the FSUIPC for FSX. Is this true for the language SDKs as well?

Yes, the interface is the same.

Using the Java SDK, I have an issue that I can't resolve. Everytime I run the provided test application, the phrase "Hello, world" appears in the FS2004 window. The letters are red and are overlayed on a green bar that stretches the width of the window. I can't find anywhere in the provided code that would cause this to happen. Any ideas?

That's obtained by sending the string "Hello world" to FSUIPC offset 3380 and then writing a control value to offset 32FA. Please check the SDK documentation.

It sounds like the provided test application is designed to do exactly this, in other words the FS equivalent of the standard Hello World test used for introducing every language!

What did you expect it to do? Is there no source code in the example?

Pete,

The test application provided with the SDK connects to FS2004 and then prints out various attributes about the aircraft to stdout. I've done a search for the words "hello world" to and found nothing. I did the search on the test code as well as the Java SDK source both. I also searched on the two offsets you provided in your previous reply, they do not appear either. Is it possible that the "Hello, world" phrase is hidding in the .dll file that is part of the Java SDK? I have provided the code from the test application.

I have been able to make changes to this code, recompile and see the expected results, so I know that the "Hello, world" string is not in the .class file that I am executing.

Well, the source code for the Java SDK does contain the "Hello, world" sting. The EngineType method in the FSAircraft class pokes the string into FS. I used the Windoze search to try an locate this string originally. For some reason the Windoze search tool was ignoring all .java files. As soon as I renamed the file from FSAircraft.java to FSAircraft.java.txt, the Windoze search tool found the string. Here is a thread on the subject.
