View 3 RepliesAdd Description To Functions And Function Parameters?
Apr 19, 2011I'm writing a VB.NET function with a ton of overloads. I've seen that most .NET functions have parameter descriptions in IntelliSense. For example, when typing in String.Compare(, IntelliSense says Compares two specified System.String objects and returns... you get the idea. This description changes and you click through different overloaded versions of the same functions. When you start typing in something for a parameter, it describes the parameter you're currently inputting as well. Example: strA: The first string to compare..

View 1 RepliesArguments / Parameters And Variables Inside Shared Functions
May 19, 2011Well I am a new to VB.NET, converting a legacy system to .NET world. Recently I have been reviewing the already existing code since I joined the project quite late in the team. I find that there are many shared functions (not shared class) inside many classes. I doubt this may create some problem if two requests ( i.e two different HTTP request to the same method as it's a WCF application, of course exposed methods are not shared but internally called methods are shared) comes to the same shared method and both the calls to the method may have different method parameters/arguments, overwriting each other's arguments. In short, if shared method has a list of arguments which is going to be processed, is there any chance of inconsistencies in the light of multiple access to the shared method via two http requests.

View 4 RepliesVS 2008 Subs/Functions Intellisense Listing Values To Parameters Upon Using It
May 30, 2010I'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
Why Does VS (C#) Default Parameters To Pass-by-value
May 11, 2010Just kind of curious about something: why does VS (vb and C#) default params to pass-by-value?I almost never need or want to pass anything by value. Maybe this is some reflection on the way I code. I would never manipulate a value type param directly; i would just return the new value from a private variable... and I just don't see the need to do the background work all the time to add copies of everything to the stack. Why wouldn't I just about always want to pass-by-ref?

Can A Generic List Of T Be Passed To Function Similar To Way An Array Is Passed?
Mar 23, 2012I want to pass a List of T where T is an object I've created that has about ten properties (strings, dates and integers).The lst passes to the function successfully. I am also passing an New T of the Object (itm as T).I can see all the values (see image below), but because it's generic I cannot seem to retrieve the property values and I cannot figure out how to iterate through the properties of each itm as they are retrieved in the For Each.[code]

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:
