Why Encoding.Default.GetBytes() Returns Different Results In C#

May 29, 2009

We recently came across some sample code from a vendor for hashing a secret key for a web service call, their sample was in VB.NET which we converted to C#. This caused the hashing to produce different input. It turns out the way they were generating the key for the encryption was by converting a char array to a string and back to a byte array. This led me to the discovery that VB.NET and C#'s default encoder work differently with some characters.

C#:
Console.Write(Encoding.Default.GetBytes(new char[] { (char)149 })[0]);

VB:
Dim b As Char() = {Chr(149)}
Console.WriteLine(Encoding.Default.GetBytes(b)(0))

The C# output is 63, while VB is the correct byte value of 149.if you use any other value, like 145, etc, the output matches.Walking through the debugging, both VB and C# default encoder is SBCSCodePageEncoding.I have corrected the sample code by directly initializing a byte array, which it should have been in the first place, but I still want to know why the encoder, which should not be language specific, appears to be just that.

Query Performed Returns Results In Reverse For Some Options?

Apr 6, 2010

I am trying to perform a query on an Access 2007 Database Using Visual Basic 2008. My database has a table tblStudents contains a field named Gender with Male/Female options. In VB 2008 I set up a form with a Combo box where the user can select either Male or Female to perform a query and navigate through the returned results. When i choose the 1st option in the Combo box the results are returned in the order. However when i choose the 2nd option in the combo box, i get the results in reverse order which i still could not find the reason why it does that. Here is my Code for the query and the Execute Query Button:

Private Sub DisplayGenderData(ByVal gender As String)
connUsers.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:StudentRecords.accdb;Jet OLEDB:Database Password=testing;"
' Open the connection.

VS 2010 Reading Remote Registry With WMI Returns No Results

Feb 9, 2012

I am trying to read the HKEY_USERS hive of a remote machine with this Class

Imports System.Management
Imports System.Management.Instrumentation
Public Enum RegHive As UInteger

[Code]....

The value of sSubKeyName is the user's SID + "" + Network (e.g. S-1-5-21-1606980848-2025429265-839522115-560021Network). Now under that key are various subkeys containing mapped drive letters. But it never returns anything.

Strangely, if I use the OpenRemoteBaseKey method it works BUT I don't want to use that because using WMI lets me specify alternate credentials and OpenRemoteBaseKey doesn't

Asp.net - LDAP User Attribute Request Returns Unusual Results?

May 31, 2012

I'm struggling to return user details from AD using LDAP, after i have authenticated that the user exists. I am using a simple auth method as follows:

Function AuthenticateUser(path As String, user As String, pass As String) As Boolean
Dim de As New DirectoryEntry(path, user, pass, AuthenticationTypes.Secure)
Try
Dim ds As DirectorySearcher = New DirectorySearcher(de)
Dim result As SearchResult = ds.FindOne()

[Code]...

the problem is that "distinguishedName" returns "DC=our-domain,DC=co,DC=uk" and "name" returns just "our-domain", not the name of the user that has just been auth'ed

Note: the displayName.text outputs are purely for debug purposes.I have tried various combos of requests but nothing seems to return USER details. ETA: to the security police: this is all within a https connection, I'm not sending passwords about in plain text!

Show The Final Results Instead Of The Results Real-time

Sep 28, 2010

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?

Null Check Always Returns Null, If Removed Returns Object Reference Not Set To An Instance Of An Object

Jun 24, 2010

I have some code which gets child items for a menu via the GetChildren function which takes a list of menuData: Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))

For Each menuData As MenuData In builtMenu
If menuData.Children IsNot Nothing Then
menuData.Children.AddRange(GetChildren(menuData))
End If
Next

If I check if menudata.children isnot nothing, it always is nothing because the GetChildren function is yet to run (providing the child items, which do exist). If I remove this check and just have this code:

Dim builtMenu As New List(Of MenuData)(_rawData.FindAll(Function(item) item.GroupingID = 0))

For Each menuData As MenuData In builtMenu
menuData.Children.AddRange(GetChildren(menuData))
Next

Then I am presented with a Object reference not set to an instance of an object error on menuData.Children.AddRange(GetChildren(menuData))

Binarysearch Returns -136?

Oct 28, 2009

I've got my text files read into an array.Which was step 1 .My code so far is:

Note: textSKU is just a text box. No event handler associated.

Private Sub BtnSeacrch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnSeacrch.Click
Dim objCA As New System.IO.StreamReader(ofdCA.FileName)
System.IO.StreamReader(ofdWarehouse.FileName)[code]....

The message box is mostly just to test to see if it's finding the line. And the problem is it's returning -136.Which I'm pretty sure can't be a value in the array ( actually very sure, as I tested it just to be sure, and it says it's out of bounds).I know it's in the array, as when I change returnvalueCA to a...7 for example, it outputs the correct line from the .csv file.

Edit: Index was outside the bounds of the array. is what the debugger says, as it's trying to output the value of SKUSheet(-136)

GetVSTOObject Returns Nothing?

Jan 5, 2010

as a workaround for the Locale bug in Office Interop I wanted to use VSTO but if I call

app.ActiveWorkbook.GetVstoObject()

then it returns nothing. I'm working from a .NET 2.0 Visual Basic Application project. This is not an add in or a special VSTO project. I have added the required Imports and References.

Dim app As New Excel.Application
app.Caption = "Rapport"
app.Visible = True
app.Workbooks.Add()
Dim tmp As Object = app.ActiveWorkbook.VBProject
Dim book As Workbook = app.ActiveWorkbook.GetVstoObject() 'Returns Nothing

This is a school project and it needs to be finished by the end of next week

Vb6 App.Path Returns Only URI Now?

Recently (I have no idea when) App.Path in VB6 started to return a URI rather than an absolute path for the location. Instead of returning something like "C:program filesmyapplication it has begun returning "\sacoc$program filesmyapplication"Has anyone else noticed this?

It breaks a whole crap-load of my code.It seems like MS, in their infinite wisdom, have decided there is some security breach with the way it was returned before - just guessing.

.net - Asc(Chr(254)) Returns 116 In .Net 1.1 When Language Is Hungarian?

Oct 5, 2009

I set the culture to Hungarian language, and Chr() seems to be broken.

System.Threading.Thread.CurrentThread.CurrentCulture = "hu-US"
System.Threading.Thread.CurrentThread.CurrentUICulture = "hu-US"
Chr(254)

This returns "ţ" when it should be "þ" However, Asc("ţ") returns 116. This: Asc(Chr(254)) returns 116.Why would Asc() and Chr() be different?I checked and the 'wide' functions do work correctly: ascw(chrw(254)) = 254

C++ DLL Returns Only First Character To An Application?

May 2, 2012

One of our technicians asked my to write a small library file in which he would pass a filename and an integer. The library would load the text file and find the integer in the text file referenced by the file name and return a string back to his program. He is working in a third party application that uses VB as its scripting language.So, not wanting to worry about the .net install on some of the older machines that he has his equipment installed on I decided to take a crack at C++ (VS 2010). I am doing applications development in C# and the last time I compiled any C++ code was in VS 6, but I though how hard can it be? Well I am typing here so things have taken a decidedly wrong turn. I started out with the C++ Side.

#include <WTypes.h>
#include <comutil.h>
#include <string.h>the BSTR. Tried SysAlloc, didnt work.

[code]....

If I pass a String to a BSTR as a parameter then pass it back again (like the file name) then the VB side reads in the entire string.
