I have quite a long java class and I need it displayed within a text box, with a scroll bar, in a powerpoint presentation. I have only just found out that powerpoint can use vb to create macros. I would want it displayed in the powerpoint presentation correctly formatted etc. [Code]

In 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.
I 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?

View 1 RepliesI 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 RepliesI 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.

I'm new here at Dream.In.Code, and this is my first question! To begin I would like to say I am new to Java but not new to coding, I am using Eclipse IDE 3.7 for Java and only have a basic knowledge of Java. I understand how it works; I don't know very much code... On to my question! I am wishing to create a simple JAR file for my own education/demonstration. Yet despite my searching and reading through my book I cannot find any relevant information about how JAR files are constructed. So, what defines a JAR file? How does one compile/make one?
P.S. I wish to work with JAR files because of their seeming simplistic nature and cross-compatibility. This is true, yes?My dearest apologies, I realise I posted this in the wrong forum. May a moderator move it for me?
I have a program that allows a user to type java code into a rich text box and then compile it using the java compiler. Whenever I try to compile the code that I have written I get an error that says that I have an illegal character at the beginning of my code that is not there. This is the error the compiler is giving me:

View 3 RepliesI've only used type inference when using LINQ in VB.NET. However, I'm aware that type inference can be used in other parts of the language, as demonstrated below:
Dim i = 1 'i is inferred to be an Integer
Dim s = "Hoi" 's is inferred to be a string
Dim Temperatures(10) as Double
[code]....
I can see how type inference reduces the amount of typing I would need to write a piece of code and can also make it quicker to change the type of a base variable (such as Temperatures(10) above) as you wouldn't need to change the types of all other variables that access it (such as T). However, I was concerned that the lack of an explicit declaration of type might make the code harder to read, say during a code inspection, as it may not be immediately obvious what type a variable is. For example, by looking at just the For loop above, you might correclty assume that T is some floating point value, but wouldn't be able to tell if it's single- or double-precision without looking back at the declaration of Temperatures. Depending on how the code is written, Temperatures could be declared much earlier and would thus require the reader to go back and find the declaration and then resume reading. Admittedly, when using a good IDE, this is not so much of an issue, as a quick hover of the mouse cursor over the variable name reveals the type.
Also, I would imagine that using type inference in some situations could introduce some bugs when attempting to change the code. Consider the following (admittedly contrived) example, assuming that the classes A and B do completely different things.
Class A
Public Sub DoSomething()
End Sub
End Class
[code]....
It is possible to change the type of ObjectList from A to B and the code would compile, but would function differently, which could manifest as a bug in other parts of the code.With some examples of type inference, I would imagine that most people would agree that its use has no negative affect on readability or maintainability. For example, in Java 7, the following can be used:
ArrayList<String> a = new ArrayList<>(); // The constructor type is inferred from the declaration.
instead of
ArrayList<String> a = new ArrayList<String>();
I'm trying to make a vb.net application that has got 2 textboxes, 7 radio buttons and 2 buttons(one named compile and the other 'run'). How can I load the content of a C/C++(or any programming language) file into the 1st textbox and on clicking the compile button, i should be able to show the errors or the C/C++ program in the 2nd textbox. On clicking Run, I should be able to show the output in the 2nd textbox. In short, I want to use the 2nd textbox as a terminal/console. The radio buttons are 4 selecting the language C or C++ or python or C# or java or perl or vb.R d compilers of all these languages present in .net?

View 1 RepliesThe project I'm attempting to accomplish has to do with real estate. What I would like to do is go to a URL, automatically enter login information, once logged on, be able to grab certain pieces of text from the page, and then paste those pieces of text into another online application that also requires a login.
That probably sounded a little complicated but basically all I'm doing is putting text into textboxes and then pressing buttons. It would make the job much easier if it were automated.
I searched the forums and found that the webControl module seemed to be the place to start so i enabled it in my Toolbox.
