I am making a Texas hold'em poker game for my class project. I already have the cards in the game through an image list. I am now trying to compare the player cards with the flop, turn, and river card to tell the player what they have and if they have won or not. I have tried a number of different things but have come up short. This is the last thing I tried[code]...

it's a log in form and I need to put case-sensitive validation in other words if your Username = Admin then Admin != admin Consider this code block (VB is really unfamiliar for me so break it to me gently ^^) This is after it has matched a record in the database to the parameter passed to the function LogIn()

The problem I have here seems to me that the comparison between is crop_year =? where ? is the placeholder for Convert.ToInt32(cyrNote.SelectedItem.Trim) which is a value i get from a combobox cyrNote and try to convert it to an integer using Convert.ToInt32() so that it can be compared with the database value crop_year which is defined as integer in the database.
The problem here though is that the select returns null. I tried to replace the placeholder ? with a known value like "2011" and it returned a value. This means to me that my comparison crop_year=Convert.ToInt32(cyrNote.SelectedItem.Trim) is negative yet I expect something positive. I've tried to google on how to convert to integer and that is the best I could get.

View 2 RepliesIs there anyway to convert an image file bytes array into an array of the real RGB values of that image?
I don't really want to use GDI+ or the System.Drawing library, but simply apply a certain calculation/processing to every byte of the image file and get another array that contains the RGB values of every pixel in that image. I know it could be done as I know how to do it in a different programming language (Python) but not in Visual Basic.
I'm having issues with returning a list of strings of the .Value of a Linq query:
Dim details = <Details>
<Vector size="5">
<Item>Syntactic Structures</Item>
<Item>Introduction</Item>
<Item>The Independence of Grammar</Item>
[Code]...
Is correct in that it returns the list of XElements I want (items 1 - 4, base 0), but I really just need a list of strings for the .Value of those XElements. Maybe I'm just dense here, but anything I've tried in the chapterTitles query isn't working (appending with .ToList.ToString, etc.). details.<Vector>.<Item>.Skip(1).Take(4).Value just returns the first XElement's value.

View 6 RepliesCreate a function named DecimalDegrees to refactor the code that converts a latitude or longitude into a value in decimal degrees. (This function will be used inside the functions ValueOf and Distance.)
Task 2a: Write the code for the function DecimalDegrees with an input parameter for DegreeString as type string, and returns the value as type Double.
Here is my code for the function part
Private Function DecimalDegrees(ByVal DegreeString As String, ByVal degrees As Double, ByVal minutes As Double,
ByVal seconds As Double, ByVal ID As Integer) As Double
I am having difficulties with the 2nd part which is I believe to take the code for the calc1 and calc2 buttons and somehow get it to convert to decimal degrees by the function I have created. The buttons would then be removed as the code would automatically take the latitude and longitude and convert the degrees, minutes and seconds into a decimal.
Here is the code for the current buttons:
Dim StartPtr, StopPtr As Integer
'To Replace Calculator 1 Button
'Convert degrees before passing argument - Latitude
StartPtr = 0

View 3 RepliesI'm creating an emulator for a device to simulate wave forms. My challenge is that when I try to convert the output of the following code, I can't convert the Math.Sin's double output into byte values that lend themselves to the byte array format required by an existing graphing control as listed at bottom below. I''m not sure how to handle this when the sin function creates negative values but the byte values will need to be positive and basically 'shifted up' so that anything over 127 is negative. (0 - 255) unsigned. BitConverter.GetBytes has been suggested but THIS is the result of that attempt.

Possible Duplicate: Fastest serializer and deserializer with lowest memory footprint in C#?
I'm using BinaryFormatter class to serialize an structure or a class. (after serialization, I'm going to encrypt the serialized file before saving. (And of course decrypt it before deserialization))But I heard that some other serialization classes are present in .Net Framework. Like XmlSerializer, JavaScriptSerializer, DataContractSerializer and protobuf-net.I want to know, which one is best for me?Less RAM space needed for serialize/deserialize is the most important thing for me. Also speed is important.
