I'm new to VB but completly new. I've dabbled with it a bit before but mostly from copying and pasting code from online. Is there a good book that I can purchase that will show me the ropes of the basics?

View 1 RepliesI am starting off in the .NET world and wanted to know what a great beginner book would be that would explain how to use asp.net, vb and SQL.
I hear "Learning Visual Basic" is a good series but wanted to see if there were anymore out there.
I'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.

View 15 RepliesCan anyone recommend a good VB book that will teach functions, file IO, arrays, recursion etc. A lot of the ones I have looked at are very basic I started Sam teach yourself VB 2010 in 24hrs but a lot of it didn't relate to what we do in college.
View 2 RepliesIn my applications I use objects and classes, but when reading SO topics, I have the idea I don't use real OOP principles. For example, I never use inheritance or interfaces. Therefore, I am trying to learn proper OOP (in VB.NET), but I find some concepts quite hard to understand (even after reading a lot about the subjects on SO).So I'm trying to find a book or resource with good practical real-world examples. For instance, I kind of understand examples like using an interface for both Dog and Cat classes when using a EatFood method, but I find it hard to relate it to real-world cases.Ideally these books or resources should cover explanations about:
- when and why to use inheritance or interfaces or abstract classes
- when and why to use private, public, protected, virtual etc.
- best practices in dependency injection /inversion of control
- when to use aspect oriented programming
- using of constructors
- solid principles
- singletons
- encapsulation
Perhaps it's a mix of all kinds of concepts, but I think these are all related to OOP, please correct me if I'm wrong.I would prefer a book/resource with VB.NET examples, but this might be difficult?
I'm still a noobie whe it comes to VB.NET but I am going to be specifically orking/interacting with websites such as passing variables to textboxes, clicking on buttons, etc.
View 1 RepliesI am a EE graduate from about a year and a half ago working in the semiconductor industry as a hardware/test engineer. I wan't to learn VB to do lab level data test and acquisition. I am learning this in my free time at work and home, and I would be using VB to talk with different electronic equipment through GBIP to source, measure, and record data. Anyone have any good ideas of a good book for such applications?? I know there are a ton of books and courses out there, but 99.9% of that information is not going to be needed for my industry application. I also took a few C classes in college, and I have some experience with labview so I am not a total noob to programming. So if anyone has a good book, or refferences that would be really appreciated.Also what version of VB would you recomend me learning?

I'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

Possible Duplicate: Which language should I pick up: VB.Net or C# I'm trying to make a descision on learning VB.NET or C# as my first .NET language. I'm aware that bith languages can achieve the same things since both ultimately use the .NET framework. I'm also aware that C# has a similar syntax to both Java and C/C++, so I definitely see the benefits with this.
But how about the future of VB.NET? Will it be maintained in the years to come?I do know a bit of python, so would that make C# easier to learn?
I am looking to switch to C#. I come from a C / C++ background but C# is a little different for me. I am switching mainly because of Silverlight and MVVM; all examples are in C#. Any information is in C# and I am confused when I read through it all.
What is a good place to start learning C# when starting with existing C / C++ knowledge?

View 3 RepliesI'm a C# programmer who needs to pick up some VB. The syntax differences are easy enough to figure out, but there are other things I'll need more of a tutorial on. For example, VB's "strict" mode in Visual Studio is something essential to me, but something I wouldn't have learned just by comparing language syntax. Any recommendations on how to pick up VB quickly, yet thoroughly? I can't stand to work through a 1000 page book introducing VB to novices.

One of the particular issues that I am having is that I've set up a table with approximately six columns. I have this shown on the main form as a datagridview with only two of the columns shown. To edit / add a new record, I have set up a button to load a new form with the details of the datagridview showing in textboxes (for all six columns). So, if the user were to select an entry on the main form page and then click on the edit/add button it would bring up the row's information in their respected textboxes. From there the user would be able to edit and then save the changes. I'm having difficulty bringing up the form with the selected row's information.
