XMLSerialization (VS2008) : The Type A Was Not Expected
Mar 4, 2009I have a class A that has a SectList (which inherits from ArrayList) of objects of class B.I make class A <Serializable()>, as well as SectList and B.objects of class B are added to the SectList as the program runs.Upon serialization, I get the message that B is unexpected and that I should use XMLInclude to specify classes that are not known statically. How and where exactly should I use XMLInclude ?What is XMLInclude's parameter ? <XmlInclude(GetType(B))> ?Where is a good and solid explanation of serialization in VB,, where these phenomenae are well explained ?

Point Type (pair Of Values) Using Decimal Or Double?
Apr 24, 2010Is there such a thing as a type similar to a point, but contains a pair of decimals, or a pair of doubles, rather than integers? I searched the forums and google with no luck. I can't believe this has never come up before, I must have been using the wrong search terms.

Sep 27, 2011I have a very small VS2008 Winforms project that will not start.When I attempt to start debugging the project, I get the message:'<form>' is a type in '<project>' and cannot be used in an expression.From the file .Designer.vb.The problem is that is indeed a form. If I create a new WinForm and set the startup object to the new form, I get the same message.When I attempt to check the "Enable application framework" checkbox in the Project properties, I get the message "Startup object must be a form when 'Enable application framework' is checked.I've tried creating a new project and moving all the code and designer objects to a new form file in the new project, and same result.Other projects on the same computer run fine.

.net - ByRef Underlined With "Expression Expected" Error When Trying To Pass In A Object Of Type List(Of ClsFooDetail)?
Mar 3, 2010I work with C# 99% of the time. However, I'm having to update some legacy VB.Net code and encountering an issue with VB.Net code syntax. The error that I get is "ByRef" is underlined and "Expected Expression" tag shows up when you hover over "ByRef". The "FooDetail.Load" function is written in C# and expects a List object passed as reference. Don't have any trouble using the same function in other C# classes. Can someone indicate what is wrong with below VB.Net code.
Dim FooDetail As New clsFooDetail()
FooDetail.FooID = FooID
Dim lstFooDetail As New List(Of clsFooDetail)
FooDetail.Load(ConnectionString, "Stored Procedure", ByRef lstFooDetail as System.Collection.List(Of(clsFooDetail))

View 2 RepliesVS 2010 : Search For Text Within A String (Starting Point And Ending Point)?
Dec 31, 2010I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

Calculating Point-to-point Directions On A 2-D Grid?
Mar 11, 2012I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize

View 1 RepliesMove From Point A To Point B Along An Angle?
Mar 14, 2009I need to move an ellipse from a known point on the screen to another known point on the screen.
I've tried using For.....Loops with less than desired results.
I can't remember everything I've tried, a lot of trial and error has been layed to waste. Lol
I've ended up with this code after putting together what I've tried, what I've learned elsewhere, and a couple of posts I've read on here.
All I want to do is move the ellipse from one point to the other along a straight line that forms the angle between the two points (X1,Y1) and (X2,Y2), make it grow from 2 pixels at it's start, to about 80 pixels by the time it reaches half way, then shrink from 80 pixels back down to 2 pixels by the time it reaches the point (X2,Y2).
Easier said than done.
Here's what I have at the present.....
Dim W As Integer
Dim H As Integer
Dim Num As Integer

....This seems like such a simple task, yet it's been a week since I came up with the idea, and I've had little success.

May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).
