Calling Java Class In Vb?
May 18, 2009In order to call a java class in vb, I found the following procedure and I tried.
(1) create a java class (eg: MyTest .java)
as
public class MyTest
{ public int myfunction(int value1, int value2) { return value1+value2; }
(2) compile to get a MyTest.class
(3)register Mytest.class using javareg.exe file from Microsoft SDK for Java using javareg /register /class:MyTest /progid:MyTest and see a MessageBox displayed with Succesfull register Class message
(4) copy MyTest.class to C:WinntJavaTrustlib
(5) open a New Project on Visual Basic. And paste this brief code on the Form Load event for example and run it. Set x = CreateObject("MyTest") MsgBox x.myfunction(1, 1)
I did all the above steps but when I run the vb program (Step 5), I get the error message "Cannot create ActiveX component". Unhandled Exception message.
I am using Java 1.5 and Visual Studio 2008.
Execute Java Class From .Net?
Jan 29, 2011I have a class in java "Main.class", wrote and stored in %TEMP%. When executing the class through VB.Net Shell, eg:
Shell("cmd.exe /k java %TEMP%Main.class")
Also when trying to execute manually through CMD: "java %TEMP%Main.class", I am returned with:
Exception in thread "main" java.lang.NoClassDefFoundError: C:UsersBenAppData
LocalTempMain/class
Caused by: java.lang.ClassNotFoundException: C:UsersBenAppDataLocalTempMai
n.class
[code]....
However, when I execute Main.class manually through compile.bat - the class runs fine. What is the reasoning for this?
Importing Class From C++ Dll?
Dec 11, 2011Ok, I've been fighting this for days and so far haven't found very much helpful information on the web. Apparently this isn't a very popular thing to do since there isn't much out there. I'm hoping someone here can help me out. I don't know very much about dll's or implementing classes in vb, so please correct me if my thinking is wrong.If it's relavent I'm using Visual Studio 2010.I'm working on a much larger project, so I've created a greatly simplified version to test and and ask questions about.Here's the situation:I've created a class in c++ that I now need to create an interface for in vb. As I said before I've created a much simpler class and compiled it as a dll. There are two functions in the dll:
[code]...
The setTestVar function simply sets the value of a member variable, and getTestVar returns the value of that variable. I load the setTestVar function from the dll like this:
[code]...
Then when I click a button, I call:setTestVar(9) This results in an "AccessViolationException was unhandled" error. "Attempted to read or write protected memory...."After thinking about it, I guess this would make sense if the constructor in the dll was never called (and thus the variable into which I'm trying to store data doesn't exist).So the question becomes, how do I call the constructor in the dll from vb such that I have some sort of handle or reference to that object when the call returns from the dll? Without a handle, I won't be able to access any of the member variables. Is this thinking close to being correct? Or is the problem something entirely different?So again, how do I call the constructor in the dll (from vb) and somehow have access (from vb) to the object that it creates?

View 1 RepliesIntegrating Java Class To Be Used In Application
Apr 13, 2012I have been asked to create a project in vb.net which needs to integrate a java class created by Apple (Autoingestion.class) to pull sales records and so on.I found out a couple of questions here on stackoverflow but none of the answers given worked for me when trying to integrate this java class in my .net application.For example this question seemed to be what I really needed but when trying to compile this java class (I decompiled it first using Java Decompiler), it generally throws some errors.All I need is to use this class in my application to invoke a method.Does anyone know how to pull this out without much ninja-ing?
View 1 RepliesConvert Java Class To Vb 2008 Application?
Oct 29, 2009I wrote a Java class that parses a bpel text file and then returns a count of the number of occurences of certain words. I wanted to convert it to VB2008 Forms application, so that its results are displayed in a TextBox and not on the console. The problem is that VB2008 lacks Scanner and StringTokenizer classes, which are in my current Java class. Am not sure how to get the same functionality (or better) in VB2008. Can someone out there help to convert this class.

Java - Distance Units In Com.vividsolutions.jts.geom.Geometry Class?

IDE :: Importing A Type Lib With A Module Results In Empty Class?
Oct 27, 2011We have a typelib where we define some constants. One of our sets of constants is created using the module keyword:
module MyConstants
{
const int Const1 = 1;
};
I use tlbimp.exe in a bat file to generate a primary interop assembly for internal use.If I create a VB .net project and add a reference and browse to the .tlb file and import it, the result I see in the browser window is a class named MyConstants. If I click the class, the right hand pane is empty - the class contains absolutely nothing.
If I add a reference to the primary interop assembly, I also see the class MyConstants int he browser window. When I click the class, the constants show up.This is in Visual Studio 2010 (RTM). Why does VB .NET add reference via brwose to the .tlb file differ in this case? Is this a bug in VB .NET or the tlbimp.exe tool?
Importing An Enum Into A Visual Basic Class So That It Becomes Inheritable
Nov 16, 2011Here is what I have in my file
Option Strict On
Imports MyNameSpace.MyEnum
Public Class AwesomeClass
[Code].....
But since MyEnum isn't defined in the subclass it won't work. I am not very familiar with what these types of things are called, but I think that I am import a type definition of sorts. Since I am Importing, and not defining, it is only available in the first file. Basically, I want to include MyEnum as part of the class but I don't how to do it. I don't want to copy/paste it over, and I don't really want to write Imports ... at the top of all of my subclasses.
Can't Define A Specific Instance Of Static Method Created As A Java Class
Mar 12, 2011Under Visual Basic 2010, I am trying to define a specific instance of a static method that was created as a Java class. I have a vendor supplied dll added in as a reference.[code]...
But, I can't seem to define a specific instance of this method. Using "IntegrationMethod.getIntegrationMode()"always returns a value of zero.
There doesn't appear to be any way to "setIntegrationMode" to a specific value.

When I asked the vendor for assistance, their response was: "

Sep 26, 2011`I want to encode my string using .net and pass it to a java program. I am using the same program for encryption and decryption on both the sides. But the java program and .net programs are returning different MD5 hash codes.Here are the codes for both my programs :
VB.net

input = UTF8Encoding.UTF8.GetBytes(sSecurityKey)
oHash = oMd5CryptoServiceProvider.ComputeHash(input)[code]....
The problem is that m.digest() from java and oHash from vb.net are different. So i cant go further with DES encryption.
