I have a VB.NET solution, just upgraded from 3.5 to 4.0. One of the classes has a private field: Private _Projection As ICalculatedPath At runtime, any time the class containing that field accesses that field, I get a FieldAccessException. The first time that field happens to get accessed is a null check in a method, and one of the th...

The possible values of PixelOffsetMode are: Invalid Default HighSpeed HighQuality None Half I'm guessing that HighQuality = Half, HighSpeed = None and Default = HighSpeed. If this is true then, like the SmoothingMode, I can offer just two simple options. Does anyone know if this is correct and, if so, where on earth did you find ...

How do I serialize and deserialize my main form (and its controls, subcontrols, their values, etc.)? Edit, for clarification. Currently I am writing the current value of each control to an .INI file, one by one and reading it back when the program is next run. Every time I add a new control, I have to remember to update that save/load...
I'm working through some Error stuff, and I've tried converting Richard Dingwall's example over to VB.NET. The problem is that I'm getting an error: Type ResourceNotFoundException is undefined '<AttributeUsage(AttributeTargets.[Class] Or AttributeTargets.Method, Inherited:=True, AllowMultiple:=False)> _' Public NotInheritable Class...

Is there a way to dynamically create an object using a string as the class name? I've been off VB for several years now, but to solve a problem in another language, I'm forced to develop a wrapper in this one. I have a factory method to dynamically create and return an object of a type based on input from elsewhere. The provided input...
I'm wrangling with issues regarding how character equipment and attributes are stored within my game. My characters and equippable items have 22 different total attributes (HP, MP, ATP, DFP). A character has their base-statistics and can equip up to four items at one time. For example: BASE ATP: 55 WEAPON ATP: 45 ARMOR1 ATP: -10...

In VB6 you could easily mark a member hidden in the object browser but still available with a check mark. In VB.Net the only way I found to make a member hidden the VBA object browser is to prefixin...
I call upon the VB ninjas out there. Here's my situation. I need to eventually be able to pass multiple models to a view. Currently I have a linq to sql class that, of course, has a bunch of generated model definitions. I need to make a model that implements multiple models. I somewhat understand how to do this in C#, but this project is...
My DataGridView is read-only - the user cannot enter data into it, so that empty row at the end (the "new" row?) just looks ugly. How can I prevent it from displaying? ...

I'm wanting to burn the contents of a folder to CD from within a VB.net project. After a few hours of research it doesn't appear as simple as I thought it would.

Starting a few weeks ago, compiling a project (VB.NET, .NET 2.0, VS 2010) has taken several times as long as before. In Task Manager, I noticed ResXtoResources.exe taking lots of CPU for a while. I've finally been able to get some data on this using MSBuild's 'Diagnostic' output setting, and comparing that output to what I see in a branc...
