Put Spaces In A C# Enum Constant?
Jul 13, 2009
Is there any way to put spaces in a C# enum constant? I've read that you can do it in VB by doing this:
Public Enum EnumWithSpaces
ConstantWithoutSpaces
[Constant With Spaces]
[Code]....
That implies to me that the CLR can handle an enum with spaces.

What's the difference between enum and constant?Are they useful in real-life programming? or do they exist solely to make coding more tidy? Do they serve any real purpose?

I have a URL lets say . some time i need to send HTTP and some time i need to send it to HTTPS for that i created a enum:
Private _protocol As Protocol
Enum Protocol
HTTP
HTTPS

Dim targetUri As String = setting.protocolType & "://www.mysite.com"

When building a class library which contains many classes, all classes uses a lot of common constants and functions, what is the best to do:
1- Declare these constants and functions as public in a module.
2- In each class declare constants and functions used by individual class as private.
The first choice is good for easy and fast implementation, but re-using a class in a different project will require importing the module to the other project.The second choice require a lot of copy/paste for code snippet but a class can be re-used in different project easily.

I'm trying to declare an enumeration and one of the names I'd like to use for an item is not usable apparently. Where I am declaring 'STEP = 3', I get this error message in visual studio: "Statement cannot appear within an Enum body. End of statement expected." Is it possible to use STEP as an item name somehow? [Code]

I just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

Which is better, using a nullable enum or adding the value None=0 to your enum list?Using nullables requires more code, but I kind of like it since it forces me to think about the possibility. Otherwise I'm liable to forget about the None enum and fail to account for it being a special case.

visual basic 2008 express
' the following lines declare the variables and constants
Dim intDiameter As Integer
Const dblPI As Double = 3.14159
Const dblAREA As Double = 140125
Dim intLabel As Integer
Private Sub PizaSliceCalculator_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]...
I made a working program to calculate piza slices, i was told i needed to declare pi and the areas as constants. when i rewrote the program it no longer works. the result keeps coming back as 0.

I have strMyColor = "Red".I would like to make lblMyLabel.BackColor to be red.Without using a variable the code would be this:
lblMyLabel.BackColor=Color.Red
I tried using the variable like this: lblMyLabel.backcolor="Color." & strMyColor
But the error is that a string can't be converted to System.Draw.Color. I understand that, as the string "Color.Red" is not the same as the VB constant Color.Red.Is there a way I can construct a valid vbConstant from a string?

I mean why? I mean to organize things I often turn modules into classes where all the methods are share.But then I thought, why not organize them into namespace?But then we can't declare constant in namespace.

Alright, So i have two forms open. One in a listview and i have another window with a browser control in it. The browser is adding data to the listview but i made it so it hides while doing this using Me.Hide(). I can make it appear if i click the menu item "Show browser" i made.when im on Form1 (the listview) and its doing its thing with the browser window hidden. It keeps making form1 flash. Well not flash but like the browser window is poping to the front (while hidden) causing me not to be able to click on anything on Form1.This happen everytime the web browser navigates somewhere.Making Form1 always on top fixes it, but it also gets on top of other programs like my web browser . I want it to be on top only to the web browser.

I need some of my initialization code to be blocked off if I am in Design Mode. This code is ran in the new method of the form, so it runs before the DesignTime Property can be set. Is there, or is there a way to setup, a compiler constant which indicates whether or not you are in Design Time. The Debug Constant doesn't work because when I run the application in Debug mode I want it to run

I currently have a table that has a few hidden text boxes... The text boxes become visible when certain actions are performed.
The table though changes size according to when the textboxes are visible or now. Ex. When the textboxes are visible the table grows, and vice versa.
