View 8 RepliesI have a solution with more than one project and the main project contains buttons to open forms from different projects that are in the same solution. Say Project1 is the main project and Project2 is the different project that gives the following error when i compile it:
Error 3 'Sub Main' is declared more than once in 'SystemInformation': SystemInformation.Program.Main(), SystemInformation.My.MyApplication.Main(Args() As String) System Information II
I have already seen other threads with this question but it does not work for me because i have more than one project.For Project2: Application Framework is disabled and the startup object is "SubMain".
I avidly create games in VB.net. Being a hobby programmer I give my games away for free. Since I'm a hobbiest without formal training I do try and educate myself on proper programming principles and follow them when programming such as OOP. There are however some things I have obviously missed being self-taught that perhaps I would know if I were formally educated. Once such issue that has really been my bane is how different classes (from now on referred to as objects) 'know' about each other WITHOUT programming specific interaction.
Okay imagine this, you have a space game and the following objects
[CODE]...............
Now each one of these objects has a Health, X,Y and Z private members and properties that are all inherited from clsSpaceEntity for argument sake. Now one way of programming collision between them would be to code out the following logic in the main game loop
[CODE].........................
Now this might seam okay if your talking about the simple example above but some of my games have tens or even HUNDREDS of objects that interact in this basic way. Is there a way in OOP to do the following... for each thing that inherits from clsSpaceEntity check against every other object that inherits this type (except itself) and if they collide then reduce health next? This sort of ability for a type of objects/class or whatever to be 'aware' of another and how they are the same/different and interact would save me tonnes and tonnes and TONNES of coding.
In VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example:
With foo
.bar()
.reset(true)
myVar = .getName()
End With
Is there any such syntax within Java?

View 2 Replies`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
md5Provider = New MD5CryptoServiceProvider()
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.

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.
