.Net/C# Equivalent Of ADSYSTEMINFO?
Nov 16, 2011
I'm looking at some old ASP code that contains the following:
Set objDSE = GetObject("LDAP://RootDSE")
Set objSysInfo = CreateObject("adsysteminfo")
Set objUser= Getobject("LDAP://" & Replace(objSysInfo.UserName,"/","/"))
dtmValue = objUser.PasswordLastChanged
[code]....
This is for an intranet app that uses integrated authentication. Is there a replacement for the ASP adsysteinfo object? I can probably port most of the LDAP calls using System.DirectoryServices.DirectoryEntry, but is there a better/easier way to do this in ASP.NET (VB.Net or C#)? how to convert the ASP object properties to DirectoryEntry properties?

I have a win2k3 domain controller that I'm setting up with a new login script
Code:
Const USERS_GROUP = "cn=users"
Set wshNetwork = CreateObject("WScript.Network")
Set objADSysInfo = CreateObject("ADSystemInfo")
[Code].....
My problem is when I query the server with GetObject(ldap), the client comes back with an error that says "No mapping is done between account names and security id's is done" or close to that, and the script ends.
This only happens on my win2k box, not my xp box. I've tested multiple win2k stations and the same thing happens. No other xp boxes experience this.

I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).

What I am trying to do is to check if a value matches one of two numbers (and easily be able to add to the numbers to compare to). Rather than doing a longer-winded way such as: [Code] I have found that this only works when SectionID is 2 or PageID is 8. If SectionID is 3 or PageID is 12 then it doesn't work. Why is this and what can I do to try to get around the problem?

I've got a large codebase which I'd like to expose to plugin authors to allow them to use VB.Net Express to code plugins for a server app, which is not available to them. My problem is that even with obfuscation, I'd rather not distribute the complete app and/or dlls, as even with obfuscation peeling apart a .NET assembly and puzzling out code is relatively easy to do. I'm interested in this because the licensor I obtain the code from requires me to protect IP and assets and while distributing .NET apps opens up the app to disassembly, keeping the server app private and allowing users to utilize a skeleton dll to code against is a happy medium.
What I'm looking for is some way or a utility to go through my server app source code and create a codeless version of the app which only contains method and property signatures.The intent is to provide a stub .NET dll for them to add as a reference and code against as if they were directly interacting with the server, without actually providing the server code to them, compiled or not. I can of course do this by hand but there are over 90 classes and hundreds of thousands of lines of code I'd rather not spend a week hand tweaking. Also, this presents a problem whenever new methods or code are added to the project. Finally, two separate projects is an even worse scenario.Because people will post suggestions that have little or nothing to do with the question, here's a short, clear example. I want to turn this class:
Public Class MyServer
Public ReadOnly Property Name() As String
Get
Return "Whatever"

In .net (c# or vb) expressions, how would you implement SQL's handy IN() functionality?i.e. value in (1, 2, 4, 7)rather than:
value = 1 or value = 2 or value = 4 or value = 7
There are obviously many ways, I'm looking for the most clean and simple!

Does C# have an equivalent to VB.Net's DirectCast?I am aware that it has () casts and the 'as' keyword, but those line up to CType and TryCast.To be clear, these keywords do the following;CType/() casts: If it is already the correct type, cast it, otherwise look for a type converter and invoke it. If no type converter is found, throw an InvalidCastException.
TryCast/"as" keyword: If it is the correct type, cast it, otherwise return null.DirectCast: If it is the correct type, cast it, otherwise throw an InvalidCastException.
EDIT: After I have spelled out the above, some people have still responded that () is equivalent, so I will expand further upon why this is not true.
DirectCast only allows for either Narrowing or Widening conversions on inheritance tree, it does not support conversions across different branches like () does.ie: C#, this compiles and runs:
//This code uses a type converter to go across an inheritance tree
double d = 10;
int i = (int)d;

i didn't want to trust this one to any number of online conversion websites that I often use.I don't need to convert the declarations, just the expression '(byte)((flen & 0xff00) >> 8)'in
byte[] sendFrameData = new byte[280
ushort flen
sendFrameData[7] = (byte)((flen & 0xff00) >> 8);

As I understand it Context menus are meant to replace the Popupmenu command as we knew it in VB6. This is fine if the menus are different than the existing main menu.Do I really have to re-create portions of the main menu for my context menus or can I somehow get the context menu to point to the main menu strip branch of my choice? (As in VB6.)

I am coding in VB.NET.
Currently, I am enclosing object initialization and usage in a Try/Catch block and then tear it down (dispose, close, set to nothing) in the Finally block. The problem is, a C# 'using' block is so easy to use and would clean things up in my code.
Is there a VB.NET equivalent? Or is my Finally block tear-down solution the only way?

I need an equivalent to dword_ptr.A dword_ptr is 32 bits long when it's compiled on a 32 bit system and 64 bits long when compiled on a 64 bit system (more on this later). Odldy enough, a dword_ptr is not a pointer rather its data. I could use the vb "object" data type except that's supposed to be a slow method.I also don't know enough about the dword_ptr to know if it is strictly set at compile time or if it is estalished at runtime.The definition from ms for a Dword_Ptr is:"Unsigned long type for pointer precision. Use when casting a pointer to a long type to perform pointer arithmetic. (Also commonly used for general 32-bit parameters that have been extended to 64 bits in 64-bit Windows. )
