Use A Function To Determine Which Card To Pla?
Apr 22, 2011
In my program i use a function to determine which card to play:
Private Sub hogere_kaart(ByVal klr$, ByVal splr, ByVal uitkomer)
(hogere_kaart= higher card, klr$=color, splr= player, uitkomer= the one who started the round)
In a former version of Visual Basic I did not have the problem that splr and uitkomer are not accepted: I get the message "All parameters must be explicitly typed if any of them are explicitly typed". Declaring them at the start of the code in DIm statements does not help.

Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

I have been struggling with my programming class from day one. I still can't seem to grasp the complete logic on how to write code. Anyhow, I have an assignment due that I am stuck on. Here is the assignment:
In this exercise, you code an application that displays a letter grade based on the average of three test scores. Open the Grade Solution (Grade Solution.sln) file, which is contained in the ClearlyVB Chapl8Grade Solution folder. Code the application,using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B.If the average is at least 70 but less than 80, the grade is C. Tf the average is at least
60 but less than 70, the grade is D. If the average is below 60, the grade is F.
You will be developing the code for the function on your own. Below the Public Class frmMain line, insert this function header:Private Function CalculateGrade(ByVal testScore1 As Decimal, ByVal testScore2 As Decimal, ByVal testscore3 As Decimal) As String
In the function, declare variables for the average score and the letter grade. Calculate the average, use IF/Elself statements to determine the letter grade, and return the letter grade. Create a subprocedure for the Click event for the btnDisplay button. It should call the CalculateGrade function with three arguments ( the three test scores from the text boxes), and display the returned value in the lblGrade box.

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.
My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for
Here's my call:
<script type="text/javascript">
function HelloWorld()
{
var yourName = $get('txtYourName').value;

I have been looking for like 3 hours trying to find a dll or anything to make a simple cards game, but everything I find is oriented to C.
In this page A FreeCell game using Cards.dll - CodeProject� they talk about just what I want, but I cannot make it work in Visual Studio 2008 using Visual Basic.net, I don�t know if that has anything to do with the Vista OS I am using.
In the page I mention the author says "There are many good articles on the net on how to use the Cards dynamic link library" and I am sure the good articles are there, but my good luck has make me looping around the same nonsense results so I end up with nothing after 3 hours search.
The game I want to make is just something for a project we must do in class, how to start making a cards game fast and simple. If someone knows about a cards dll that works fine with vbnet, that someone would be my new hero.

I have a multi input capture card (Composit, s-video, ...) and I developed a program with avicap32.dll in vb.net to connect to a webcam. But I can not use this program to connect to composite input of my capture card.It seems the capture card has a default input.
Firstly, How can I change the default input? because I want to connect to compsite input.
Secondly, is there another way to connect to my capture card?
I've been googling but I could not find any code for vb.net or C#.net. They are all in C++ and I could not traslate them to vb.net

I am trying to make a card game which can be played over the internet between users. I have already downloaded the cardGame Starter kit for Visual Basic. I plan to modify it to the game I want.I had worked with Sockets (Client-Server App) a long time ago for a small chat program for computers connected in LAN.I had the following questions:How should I start off with this Application, should I first just concentrate on making the game and then progress to trying to figure out how to make it playable over the internet?
Or should I do it the other way round?Can I attain my objective using Sockets? or do I have to use something else?Is there a tutorial available to start me off? (I Googled and "Bing"ed it but to no avail)

I would like to be able to measure the frequency of a sine wave applied to the input of a "standard" Windows sound card system.I need to do this in near real-time (not by analyzing a wav file after the event) and I need to continuously measure every half-cycle of audio and store the results in some kind of buffer that I can read into a VB app. I have tried googling for this and it seems to be a very popular question but I have not found any really good answers. Does anyone know of a DLL that could do this? I wouldn't mind paying a reasonable sum for a commercial DLL if there is such a thing.
Another related requirement is to generate sine-waves - again this must be done in near real-time and it must be possible to change each half-cylce of the waveform. For example,I might need to generate a few half-cycles of 1500 Hz to be followed (with no break in the waveform) by half-a-cycle of 2300 Hz.

I have a Credit Card Number in an XML Message and I want to use a regex to find the Credit Card Number and encrypt it. All numbers are 16 characters long and they are not always in the same place in the xml, so basically I think I just need to find a string that is 16 characters and decrypt it, but I am not sure how.
