Simplistic Poker Code For VB?

Jul 9, 2009

I've been using these boards for about a year now and I'm slowly making progress as I try to learn visual basic. My objective is to program a number of various video poker games. Many great people have helped me out in my process of learning this program, however, I still feel that I don't have a great handle on it just yet. I'm not coming in here asking for someone to do the work for me, however, I am asking if anyone out there has a very simplistic video poker game that they designed in visual basic that I could use as a reference to build my games from. Being a teacher, I realize how everyoeone learns differently, and I'm the type of person who learns best when I work backward. If I can see the end result and then work my way backwards I feel that I will have a much better understanding of how the entire process works. Does anyone out there have a simple video poker game that I can use to build my games from?

Error: A First Chance Exception Of Type 'System.InvalidOperationException' Occurred In System.Data.dll

May 5, 2011

I am using VS 2008, Office 2007, and Win7 Home Premium on my system.I have a simple application which should be a breeze to build. All I am attempting to do is pull data from an Access database with four small tables into a data grid on a windows project. Should be simple, set up the data connection, choose a datagrid from the table in the data source view, drag it onto the page and done, right?I can't get it to work. It will all work fine until I attempt to run or debug the project. The data will not show up. The data grid does, but I get this error: A first chance exception of type 'System.InvalidOperationException' occurred in System.Data.dll

As I said, the project seems to build fine, but it will not pull the data. After the initial build I get the message that Windows will show this page in Compatibility View. Is it something with Win7 Home Premium, or a setting somewhere?

C# - What Could Cause System.Timers.Timer.set_Enabled Property To Throw A System.NullReferenceException

Apr 4, 2012

Here is the stack trace:

2012-03-16 19:15:09Z E System.NullReferenceException: Object reference not set to an instance of an object.
at System.Timers.Timer.set_Enabled(Boolean value)
at System.Timers.Timer.Stop()

Here's the code:

Timer declared as private member variable.
Private _myTimer As System.Timers.Timer
Initialize timer method.

[code]....

The timer has to have a value or else the Timer.Stop() call would be throwing the exception. This is a sporadic error and I'm just trying to see if anyone has experienced this before or if anyone has any ideas of what could be causing it. It is occuring in a WinForms application in the event handler for the Elapsed event of the Timer, but it is only occuring sporadically on the users computer. I haven't been able to reproduce the error myself.
