Container For Constants In .NET?

Jun 29, 2010

Say I have some constants that depends one of other, and I decided to keep them together in a container instead of keeping it as individual constants in a class.I thought use a Structure for that scope, but compiler force me to declare a private member for that structure.

Does Constants Take Up Memory

Jan 4, 2010

i was concerned if constants take up storage. if a class had 10 integer constants at class level, will that adds up to 40bytes of storage or is that actually not true because they are constants?

what i'm trying to do: find the best place to put the constants that i need to access at class scope, and whether its best to make them shared or not. [constants are private]

Add Built-in Constants To Program?

Jul 30, 2010

It would be good if visual basic had standard math constants like pi, the Euler number, and others built-in so one doesn't have to define them each time and have the possibility of making typos. Even some of the physical constants in MKS unit could be included like the Boltzmann's Constant, speed of light, permittivity and such. Each could be a special simple like kb for the Boltzmann's constant. Or it could be a properties like phyconst.c for the speed of light, phyconst.kb for the Boltzmann's, phyconst.sb for the steffan-Boltzmann's constant, pmathconst.e for e=2.71.

Create Constants In Project?

Calculate and display the total cost of the sale, as well as the total cost of all sales and the average cost of all sales. - Clear the box for the number of yards, the total cost, and return the quality, padding, and installation settings back to their defaults. Use constants for the cost of each quality of carpeting ($4.95 for Fabulous Flat, $8.95 for Precious Plush, or $12.95 for Super Sculptured), the padding charge ($1.25 per yard), and the installation charge ($3.50 per yard).

Make Array Of Constants?

Feb 23, 2010

I've got a situation where I need a table of constants in my app. It's actually a table of 43 formatting options where the description will appear in a drop down and the detailed settings will be used by the codeIt appears that VB can't do arrays of constants. So I've fiddled around with a Constructor in a class that creates a new array then loads up each element with hard-coded .Add statements. It doesn't seem elegant though.So I then decided to try an XML file, that I load in the Constructor and assign the contents to an array. This is what I've decided is the best, most elegant, option - but I'm throwing this question in to see what you people might recommend ! The data is mostly strings

Replace VbLf And Chr() With Constants?

Mar 18, 2009

We're trying to trim the number of assemblies we load during startup, and one of the easiest to cut is the Microsoft.VisualBasic assembly. There are alot of things in it that were easy enough to replace, like Left(), but I'm struggling to find a good way to replace vbLf and Chr(). vbCrLf was easy enough to replace with Environment.NewLine, but we have a few spots where we generate content for a Unix-based system that is expecting line feeds only.

Where Are Excel VBA Constants Defined For .Net

Nov 13, 2009

I am exporting data to an Excel spreadsheet from a VB.Net 2008 application. Now I'm trying to format the spreadsheet. So I am creating macros in Excel that format the spreadsheet, and then using the code it generates in my application. The problem is that the constants used in VBA are not being recognized in VB.Net (They are recognized in VB6). I have the following imports:

Imports Microsoft.Office.Interop
Imports Microsoft.Office.Interop.Excel

Is there something else I should be importing? For example, in this line, xlNone and xlDiagonalDown are flagged as not declared.

oXL.Selection.Borders(xlDiagonalDown).LineStyle = xlNone

Changing Value Of Hardcoded Double Constants

Feb 15, 2011

after working with some VB.net files in a project, I find that somehow the values of hard coded numeric double values have changed,that is:[code]This has happened in a lot of the source files of the project.When does this replacement take place? While I can understand that the original numbers cannot be exactly represented as double, I do not want this substitution, is there some way to prevent them? Initially I thought that was some behavior of the source control system (TFS)

Constants For ASCII Control Characters?

Feb 26, 2012

I have an app that I have been recoding in vb.net formerly written in VB6. In this app I use some ASCII control codes such as ACK NAK ENQ US RS EOT. The VB6 app uses the CHR() function with the proper ASCII codes to handle these but in recoding I would like to use something more meaningful and descriptive than CHR(4) for example.

Not Picking Up Global Constants Via Intellisense?

Jan 27, 2010

In our VB.net coding project, we have a module with the code shown below. In our frmMain.vb, we use every thing you see in the modeul.

However, when happily coding along, intellisense doesn't seem to see these or pick them up.

How can we change this so Visual Studio's Intellisense picks up our constants? For example, when typing:

If System.IO.File.Exists(SERVERS_CONFIGURATION_FILES) Then

I want to be able to type something and then the dot, such as Me.whatever and have it picked up. Below is our module:

Module ConstantsAndEnums
Public Const PROGRAM_NAME As String = "Server Monitor .NET"
Public Const TOOLTIP_BUBBLE_DISPLAY_TIME As Integer = 10000

.NET Enumerations Of Symbolic Constants For String Values?

Jun 1, 2009

I have a list of rather meaningless codes that I'm processing with a VB.NET Windows application. For the business logic I'm writing to process those codes, I'd like to use meaningful constants (like ServiceNotCovered or MemberNotEligible) instead of the original codes (like "SNCV" and "MNEL").As far as I can tell, Enums can only map to numeric values, not to strings. So the best I've been able to come up with is a static class that exposes the constants as static readonly string fields that are internally set equal to the code values, as follows.

Public Class MyClass
private _reasonCode as String()
Public Property ReasonCode() As String

Access Private Constants In Class Attributes?

Sep 27, 2011

I have an API that I created and currently utilize successfully in C#. I am trying to create an example of interacting with the API in VB.NET (so that the QA without C# experience can still utilize it for creating automated tests).

In C# I do the following

[TestingForm(FormName= "Land Lines", CaseType= _caseType
, Application= ApplicationNameCodes.WinRDECode, HasActions= true)]
public class LandLines : RDEMainForm

[Code]....

This gives me a compile time error because it claims that FORM_NAME and CASE_TYPE is not defined, even though the class has it defined inside.

How can I use the defined constants inside the class in the class attributes?

Obtain A List Of Constants In A Class And Their Values?

Sep 21, 2009

I have a class in VB with some constants that represent the string name of my security roles. I need to be able to call a function to return to me a string array(or collection, or whatever) of the values of each of these constants. I will be using it to make sure that my databases Roles table has the same roles as coded into the application.

[Code]...

I'm looking to run a function, i.e. ClassConstantsToStringArray(gettype(Roles)) that will return to me "Administrator","Basic User","Power User" I'm know reflection is the way to go, I just don't know enough about using it yet to get what I want. I found a function on the net that would return to me the constant names in a FieldInfo array but still don't have enough smarts to make that work for me.

Const ClassName="BaseClass"
Public Sub DisplayName
MsgBox(ClassName)

What I want is for class One to display its own name, not that of the base class.
