.net - Load Up Combo Box Values Once (at Login Screen)?
Mar 10, 2011I have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"

Any Advantage To Prefixing Enum Values?
Mar 24, 2011In this post Jon Skeet pointed out that the following code should be changed to conform with the .NET naming conventions. Doing that would also decrease the amount of noise in the code.
[Code]...
I must admit, I was pretty much like a sheep and was following what others have done before me. I thought the prefix did not look right and then to have it twice did not make sense either. After looking at a couple of .NET Framework examples, it looks like this would be closer to the standard.

C# - Get Values From An Enum Into A Generic List?
Nov 21, 2011I don't know how to convert the following line from VB to C#:
Dim values As New List(Of T)(System.Enum.GetValues(GetType(T)))
My version doesn't work:
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
The best overloaded method match for 'System.Collections.Generic.List.List(System.Collections.Generic.IEnumerable)'
has some invalid arguments
The constructor-parameter doesn't take it that way - what cast (or else) am I missing?
For clarification: It is wrapped up within the following generic method
public static void BindToEnum<T>()
{
List<T> values = new List<T>(System.Enum.GetValues(typeof(T)));
//...
}

How To Get Enum Values To AutoComplete Without Typing
Sep 19, 2010In VS2008, you could write, for instance,
dim enumValue as MyEnum
enumValue =
And then as soon as you typed the =, you'd get a list of possible values of MyEnum. With VS2010, you have to type
dim enumValue as MyEnum
enumValue = MyEnum.
Before getting the list on typing the final. This makes for a lot more typing and seems to be a retrograde step ... is there an option I'm missing? (I have 'Auto List members checked in the Text Editor options under 'Basic').
