.net - Address Varaible Names Where The Name Inherently Begins With A Number?
Nov 1, 2011
Part of the challenge of writing maintainable code is a good naming convention. But sometimes a good, meaningful name involves a number being at the at the start of the variable. For example, take a 401k. Theres not another name in which to call it, and the litteral spelling of it is kind of taky (FourOhOneK).
[Code]...
I can most certainly make my own obscurities for names, but I will and whoever maintains my code more than likely get tripped up on it one day. My question is, are there any conventions within the programming community that addresses this, or is this left up to the individual programmer/policies of the company that dictate this.

I'm trying to use a number that begins with 0's, only VB insists on removing them:
Dim No = 001000 + 1
i want it to produce the output "001001" but instead it removes the zero's before the non-zero numerals. How can i change this?

I have 2 winforms, one acts as server (ie Winform:Server role) and another one as client (ie Winform: Client role). In my LAN setup, there are 6 PCs and these PCs connected to each other via a 8-port switch and each PC has more than 1 LAN card.
There is one PC running [Winform: Server role] and 5 others running the [Winform: client role]. In [Winform: Server role], I'm using following code to obtain local ip address and port number and the [Winform: Server role] will listen to all incoming TCP requests according to these auto assigned ip address and port number.
Dim Listener As System.Net.Sockets.TcpListener
Dim Client As New System.Net.Sockets.TcpClient
Dim Message As String = ""

I need to clarify my intention. My current approach to my intention maybe incorrect. I attempt to create a 'zero configuration client-server networking' and that is plug & play. The server will know where the client and vise versa. I know there is a program (i.e. MaxiVista) has done that exactly.
MaxiVista has 2 applications, i.e. server and client. Users only need to execute the server application in PC designated as server role and execute the client application in another PC designated as client role. Then the server will be able to find all executing clients in the same LAN.
My intention is just that. Plug and play 'zero configuration client-server networking' within the same LAN.

The local car rental company rents cars for 29.95 per day with unlimited mileage. There is a refueling fee of 12.95; regardless of what the level of fuel is when the car is returned. Write a program that will permit the user to input the customer's first and last names and the number of days that the car was rented. The program should compute the total charge for the car that was rented.
I have to do this:
A. using a standard window
B. Using a WPF window (And I don't even know what that means)
C. Using a console application

I have a blank form and when the use right clicks on the form, they get a context menu with any number of names in the menu. This changes depending on the situation. I can get the context menu to add/remove the list of names but when I click on one of the choices and it goes to my routine (from addhandler) I can't find the property that tells me what they clicked on...

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I have a problem with a sql query. Through the query I am trying to search database for any occurrences of string (can be anything) in a column using the SQL LIKE command. The problem is that it works fine for most of the strings say john, jim, ji"m , but does not work when i include the following characters which are ( ' , { , } , and a single quotation mark). MYSQL query takes care of these special cases by putting them in [] block whenever user enters them .But i am getting the following error when i go to query the database using the GetSelectCommand() in VB.NET
Exception Details: System.ApplicationException: Number of values provided must be equal to the number of placeholders in query.I have checked the query over and over again .. but its fine .My database server is Sql Server 2008.So my application throws the exception in this command:
Using reader As MustDisposeDataReader = _
pmSystem.DatabaseManager.GetSelectCommand(selectStatementBuilder.ToString(), New Object() {})
Where MustDisposeDataReader is an instance of a class in an internally developed library, which inherits from System.Object. pmSystem is an instance of the class PlanManagerSystem which implements the commandlayer. GetSelectCommand() takes the select command
