List Of T Find Date Or Other Property In A Object In The List - Then Return Found Object?
Sep 3, 2009After reading all the examples for list of T exists and Find and find first, none show how to handle multi-property objects. Below is bare bones example maybe someone could flesh out to show how this should be done.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DatePriceList As New List(Of DateAndPrice)
DatePriceList.Add(New DateAndPrice(Date.Parse("1/1/2000"), 10.12))
DatePriceList.Add(New DateAndPrice(Date.Parse("1/2/2000"), 11.12))

View 8 RepliesPublic-facing Property To Return Either A String OR A Numeric W/o Using 'Object'?
Nov 4, 2010So I've run into a case where I have a class that can store either a string or a numeric value, and I want a single property to return one or the other (it would be a failure for both to be set). I'm using a custom generic class to deal with the numerics (so I can use signed, unsigned, and nullables), and will be storing the string in a separate variable.
In theory, if overloading could be done based on the return type, I could do this quite easily. But .NET currently disallows this. So I am wondering if there is some other really-far-out-there trick (outside of MSIL generation via Reflection.Emit) that could accomplish the same thing.
I'm open to ideas via delegates, pointer dereferencing, generics, mystical rites, etc. Also interested in any thoughts or pros/cons of such possibilities as a learning tool. If using a standard Object is the only way to achieve what I want, then that's fine with me. But It's difficult to find the correct set of keywords to hunt down this kind of capability on Google, so I thought I'd ask here before I moved on to doing something else on the project.
Return Rows That Have A Matching String To Predefined List?
Jul 8, 20091 within each section of a SplitContainer. The left hand side will be for inputing text that is copied/pasted from a word, excell, or text file.The right hand side would be for my output. What I would like it to do is return just the rows from the left hand side that contain a match to any one of the predifined strings. This will be used to search large lists of company names and circuit IDs and return the rows with matching namesSo far I have the form created, the Splitcontainer in place along with the richtextbox on each side and a submit button at the bottom.

View 39 RepliesConvert List Of String Into An Object?
Mar 6, 2012I am looking for a way to convert my List(Of string) into an Object in vb. So in the end it would be the same as declaring Dim cArray() As Object = new Object. Can anyone point me to how i can achieve this? I cannot use the LINQ .ToArray as that creates a string array and this is not acceptable for my work. I need to pass this object into another one that has the parameter (aArray as Object).
View 4 RepliesReturn An Object As The Return Value Through A RealProxy Transparent Proxy?
Oct 7, 2010I'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string

Insert List Object As Argument In String.format
Feb 10, 2012I am trying to pass a list in string.format as the parameters to the SQL statement, but I get the following error: Index (zero based) must be greater than or equal to zero and less than the size of the argument list. I know that I can get it to work when I list out each individual list member as the arguments, but I am wondering if there is a shortcut so I can just use the list object as the only argument.

Display A List (Of Object) Which Has Single Objects And Child List (Of Object)?
Sep 6, 2011Limited to using v2.0 of .Net framework (we use VB.net) due to environmental constraints on our servers.I've got an ASP.net webpage which pulls data from a webservice that performs checks on user accounts in active directory. Operators can check multiple accounts at one time using the web interface. The webservice returns a list(of AccountCheck) objects which themselves contain single properties like username, email address, and List(of AccountError) objects which contain multiple properties.[code]What I want to do is using some kind of repeater, create multiple panels or divs which contain labels showing the username, email etc, and a gridview which has the accounterror list bound to it to show all the errors. The users could be checking 2, 5, 7 accounts at once, and is dynamic.

How To Quickly Transform A List(Of Object) Into A List(Of "Object.field")
May 29, 2012Suppose I have a list of Cat.
Public Class Cat
Public Property id As Guid
Public Property name As String
Public Property race As catRace
End Class
How can I quickly transform this List(Of Cat) into a List(Of Guid) using the id property?
I could do :
Dim newList As List(Of Guid)
For each item in catList
newList.Add(item.id)
Next
But I think there must be a way to do this faster (1 LOC). I just can't find how.

Copy List Object To Another List Object
Jun 15, 2012I am having a problem when setting VB.NET list object to another.I create an instance on ReadLocations and than create an object of ReadLocation where then I loop through ReadLocations and set ReadLocation1 equal to rl. What happens is that if I then go and change ReadLocation1 to something else (assdfhsd) it will also change the ReadLocations index. I am really confused why it would be doing that unless it is "=" sign means referencing instead of actually setting the value. Please help as I am a C# developer but the program I am modifying is in VB.NET.[code]
