I don't have a conversion for some of the Java types you're using, but the following syntax should be correct:

public static string Dcipher(string encryptedText1)
{
	try
	{
		sbyte\[\] desKeyData = {(sbyte) 0x01, (sbyte) 0x02, (sbyte) 0x03, (sbyte) 0x04, (sbyte) 0x05, (sbyte) 0x06, (sbyte) 0x07, (sbyte) 0x08};
		DESKeySpec desKeySpec = new DESKeySpec(desKeyData);
		SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");
		SecretKey key = null;
		try
		{
			key = keyFactory.generateSecret(desKeySpec);
		}
		catch (InvalidKeySpecException ex1)
		{
		}
		sbyte\[\] initVector = new sbyte\[\] {0x10, 0x10, 0x01, 0x04, 0x01, 0x01, 0x01, 0x02};

		AlgorithmParameterSpec algParamSpec = new IvParameterSpec(initVector);
		Cipher m\_decrypter = Cipher.getInstance("DES/OFB32/NoPadding");
		m\_decrypter.init(Cipher.DECRYPT\_MODE, key, algParamSpec);

		sbyte\[\] encryptedText = encryptedText1.Bytes;
		sbyte\[\] decryptedText = m\_decrypter.doFinal(encryptedText);
		return (new string(decryptedText));

	}
	catch (BadPaddingException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	catch (IllegalBlockSizeException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	catch (InvalidAlgorithmParameterException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	catch (InvalidKeyException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	catch (NoSuchPaddingException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	catch (NoSuchAlgorithmException ex)
	{
		Console.WriteLine(ex.ToString());
		Console.Write(ex.StackTrace);
	}
	return "";
}

It can almost be completely converted to C#:

using System.Windows.Forms;

public class ConfirmDeleteDialog
{
public static readonly int YES = DialogResult.Yes;
public static readonly int NO = DialogResult.No;
public static readonly int CANCEL = DialogResult.Cancel;
internal static readonly int OK = DialogResult.OK;
internal static readonly int CLOSED = JOptionPane.CLOSED_OPTION; //no equivalent to 'CLOSED_OPTION'

public static int showMessage(Component parent, string message, string title)
{
	return MessageBox.Show(parent, message, title, MessageBoxButtons.YesNo, MessageBoxIcon.Question);
}

}

Note that you can also do this with arrays:

public void MyFunction(T[] myArray){
}

All converters will offer a free trial/demo version. Try it out and compare the results with some common sense. Even if the conversion is less than 100%, it may give you something you would have missed. The main challenge of converting C/C++ code to other languages, especially with pointers, is that a C/C++ declaration alone does not tell you how something is used. This is in contrast to C# where the declaration does tell you all you need to know for a translation to other languages.

Remember, legacy VB string functions are 1-based, not 0-based, so the equivalent is:

_value = Convert.ToInt32(LStr[IValue - 1]));

There's a reason most modern languages don't support multiple inheritance.

You'll need to use the hidden VB event field (add "Event" to the event name):

Dim local As EventHandler(Of MailPoppedEventArgs) = Me.MailPoppedEvent

The problem is that for VB6, the default was "ByRef", but for VB.NET, the default is "ByVal".

David Anton Convert between VB, C#, C++, & Java www.tangiblesoftwaresolutions.com

If you don't specify "ByRef" or "ByVal", then the parameter is "ByVal" by default. You want:

Sub db_create_cs(ByRef dbc As db_connection)

David Anton Convert between VB, C#, C++, & Java www.tangiblesoftwaresolutions.com

The main thing is that the 2nd parameter should be 'ByRef':

Declare Function midiInGetDevCaps Lib "winmm.dll" Alias "midiInGetDevCapsA" (ByVal uDeviceID As Integer, ByRef lpCaps As MIDIINCAPS, ByVal uSize As Integer) As Integer

Public Structure MIDIINCAPS
Dim ManufacturerID As Short
Dim ProductID As Short
Dim DriverVersion As Integer
Dim Label As String
Dim Support As Integer
End Structure

Are you sure you want 2002 Managed C++? The pre-CLI managed C++ syntax was a failed experiment - the syntax was available only for a short time and it was quickly superceded by C++/CLI (even C++/CLI is not commonly used).

The second one will be something like:

strTextChar = static_cast(static_cast(strTextChar[0]) ^ intTemp);

David Anton Convert between VB, C#, C++, & Java www.tangiblesoftwaresolutions.com

I understand the reason people give for doing this, but as far as I'm concerned if you can remember to reverse these conditions then you can also bloody well remember to get the number of '='s right.

.NET strings can certainly be 'null' ('Nothing' in VB). The point the author was making (checking my own copy of that book), is that the old VB6 functions accepted arguments that may be Nothing, while the ones with $ after it did not. After upgrading to VB.NET, the VB.NET versions of those functions will throw an exception if you pass Nothing to them. For this reason, he suggests to try to isolate the issues before upgrading. Either way, you'll have to go through this, but the more issues you can resolve before upgrading, the less overwhelming the upgrade will be. I did a number of upgrades for clients a few years ago and I can tell you that this is true (and the book you're using is excellent).

Try System.Diagnostics.Stopwatch

If you can narrow down the affected code to a line or two, then the following VB code:

On Error Resume Next
Foo()

can be converted to:

try
{
Foo();
}
catch
{
//ignore exceptions
}

For longer code blocks, you'll have to use a separate try/empty catch for each single line of code.

Remove the 'static' keyword - it's the cause of the error (and add a semi-colon after the class closing brace).

It must be due to 'index' not being declared. Try:

For index As Integer = gNum To 1 Step -1
