I was put in a situation where I had to convert RC4 code from c# into vb
I tried getting already made codes online but they did not seem to work as the currently c# one that I have. Maybe a professional will see the mistake I am making. Both codes give a different encrypted result.
c# code:
public static string RC4(string pStrMessage, string pStrKey)
{
char[] lBytAsciiAry;
int[] lBytKeyAry;
[Code].....
my goal is to
1.Take an file(exe,dll,etc)
2.Convert it into hex
3.place that hex values in a stack
4.Execute the values inside the stack to its original form(i.e. take the elements out of stack and then convert it to a compile format)
Imports System.IO
Sub Main()
Dim fileName As String = "ABC.exe"

I am trying to convert an MP3 to a wav. The wav file is created, but I am having problems elsewhere. The label is displaying the wrong data("Cancel/Error") and the progressbar is doing nothing. I am using lame 3.98 .exe and a wrapper for the exe. I downloaded the LameShell project from codeproject. Here is a section of the wrapper class. This was originally for resampling a mp3 to mp3.

View 4 RepliesIt is a program on which logic programs can be developed, compiled and downloaded into Programmable Logic Controllers. It is fairly big and complicated and the resulting .exe file is about 2Mb. I need to develop the program further now, and would like to use VB.net. When I try loading the VB6 code into VB.net, it changes all the variables of type Integer and String into type Object. It then states all through the resulting code that the default values are not defined. I assume that if defined as Integer and String variables do not need a default value, it would assume them to be 0 and empty. Any ideas why the program changes the variable types during the converstion? All forms start with 'Option Explicit', so all variables are defined.

View 4 RepliesI'm converting a program from VB6 to VB.NET, but some parameters are declared as "Any". For example:
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory"(ByRef Destination As Any, ByRef Source As Any, ByVal length As Integer)
Private Declare Function NWDSGetContext Lib "netwin32" (ByVal context As Integer, ByVal key As Integer, ByRef Value As Any) As Integer
"As Any" is not supported in VB.NET so I'm wondering what I should change it to.

I have a COM object in C++ and VB6 and everything is compiled and packaged using Visual Studio 2003. The C++ generates the DLL, and VB6 the EXE, so from the legacy code I can call the EXE that calls the DLL and so on. I need to migrate these to Visual Studio 2008. However, I have some questions
1) I can compile the C++ and generate the DLL - ( I think is ok)2) VB.Net doesn't have the option to generate COM/ActviveX anymore as VB6, so no idea - I tried to generate windows exe and call the dll, but it doesn't work. I think because it has some COM calls.
So what is the best solution to get rid of COM/ActiveX and deliver something?
Compile in C++ and load adding references in VB.net? I tried this but the DLL doesn't load..
I'm in the process of teaching myself C# by converting an existing project and am stuck converting the following vb linq code:

Group By tagName = t.name,
v = (Aggregate p In Products Where If(p.tags IsNot Nothing, p.tags.Contains(t), Nothing) Into Sum(p.views)),
nl = (Aggregate p In Products Where If(p.tags IsNot Nothing, p.tags.Contains(t), Nothing) Into Sum(p.num_likes))

var x = Products.SelectMany(p => (p.tags != null) ? p.tags : new ObservableCollection<TagModel>());
var tags = from t in x group t by t.name into g select new { tagname=g.First().name};

I have an asp.net page WineCompDefault.aspx which was initially implemented with VB code behind. I am now trying to change the code behind to CS. I modified the page directive in the aspx page as follows:

The problem is it says "The type or namespace Public could not be found". I do not know what is wrong or missing.

I made a program a couple of months ago and decided to put it up for sale for a minimal about of basicly just to cover costs. Seems word got round and people from all sorts of places are asking if I can modify program and add features which I have done and was happy to do. I have around 57 requests in my E-Mail at the moment asking me to make a Mac version and from what I can tell, all the proccess involves is converting the .exe file to a file which can be run on the mac. Before someone offering there good faith to test it for me. I'm sorry but that won't be an option for me.Would like to run a Virtual Machine, but that would be against copy right laws. Is there any other way to test it except buying a Mac?
