I'm guessing that only about 1/5th of this code actual does anything. I would love to just plug it into a debugger and find out exactly what is going on but I gave up on that idea. The only thing I can do now is extract the base algorithms and rewrite the remaining code myself.
At this point I'm thinking that even if I had the original code at hand (uncommented), I would probably still have a headache.

You are right. Loop skipped the condition all the times. I'm not sure the original code has an issue or the decompiler caused any.
I appreciate your help all the time...

I am unable to load C# DLLs from Win32 DLL API when called from JAVA Application using JNI.
I have used Comvisible(true)property for C# DLL, i generate a TLB file for the C# DLL using REGASM and then used this to get the COM interface of the DLL.
CreateInstance Fails and Gives error as "Class Not registered".
Could anyone guide me with this?

... which suggests that the UUID value you are using does not match the entry in the registry. Check your values again to make sure they are correct.

Via JNI it is rather simple to do the following.
1. Java calls JNI.
2. JNI calls secondardy dll (not managed code.)
However when the secondary dll is managed code one must take additional steps.
There are threads dealing with this in the Oracle Java JNI forum.
I believe one (or the only way) involves the correct implementation of the 'manifest'. That term refers to .Net code (the dll) and does NOT refer to the file associated with a java jar.
As a suggestion, myself I would not use JNI unless there is a proven need for it. Instead implement an executable which one manages in Java via Runtime.exec() or ProcessBuilder. It uses a communications API to talk between the app and Java. It is easier to debug, fix and it can't crash the VM.

You have to call a method (public, web method) in your web server from the app with passing the arguments.
I appreciate your help all the time...

If I understood you correctly, you should Google "file association".

hello,
plz send me the full code in J2SE for using Web Services "sending sms from Net to Mobile"...
|

No!
Please, at least make an effort to do your own work.

Oh come on - we could at least ask him, what he is willing to pay
But I second that he should have made directly a high, not to be misunderstanding, kind of overwhelming financial offer...
I would do it for the same amount the Winkelvoss-Brothers got from Facebook. Sounds like a fair price for me.

Torsten
I never finish anyth...

hi how are you today
(SORRY FOR MY BAD ENGLISH)
i don't know what this question about.. maybe it is about versions of NetBeans..
i want to sent something from Mobile Application using J2ME to a Server and then send a response from Server to Mobile
so i found a video tutorial in Youtube , and it is very useful to help me the first steps in my project
but the problem that in the video , he (the makers of video) begins with new project and he selected an "Enterprise" project ..
and then he complete his works with building a new Session ..
in my NetBeans there is no "Enterprise" project option , i mean when i make a new project i don't found an Enterprise project..
i think that J2EE solves the problem, but in J2EE there is no Session option
how can i allow my NetBeans to built an "Enterprise" project?
thank you all

Drag the object onto your JPanel or wherever you want it and then try adjusting the properties[^].
