How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.
I love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.
I need to compute the percentage of games won and games lost. I keep getting errors and it's driving me up a wall. I've changed my code so many times that I don't really remember what it was like when I started.

i am trying to make a robot that i can talk to(not yet) and tell it to goto places 1st task it to figure out how to use an inbuilt webcam in my net book and do an image Recognition for walls stars eg 2nd task is to see if i can get it to use my server to help compute the images because my net book is very slow 3rd is speech to text now can all of these be done in vb.net?
I have been given the prep material for my AS Level (Year 12) computer programming exam based around dice cricket. Written in VB 2008.
In the exam we are supposed to change bits based upon the scenario. The scenario and skeleton code are attached.
I have looked through the code so far and made some guesses to what I think may be on the test:
[code...]
if there is anything I am missing which they think I could be asked on the test. I then have to go away and figure out how to program.
So by asking on here, I am not trying to find out coding answers - I do want to figure that out myself. I just want to see if there is anything else I possibly could be asked?
I've had experience with using hashvalues from String objects. E.g., if I have StringA and StringB both equal to "foo", they'll both compute out the same hashvalue, because they're set to equal values. Now what if I have a List, with T being a native data type. If I tried to compute the hashvalue of ListA and ListB, assuming that they'd both be the same size and contain the same information, wouldn't they have equal hashvalues as well?
Assuming as sample dataset of 'byte' with a length of 5 {5,2,0,1,3}
I am trying to write code to compute the Efield on a point P in both the x and y direction, from a charged ring. double y_eField = (_ke_value * _dq * (Sin_angle) / (Math.Pow(r, r)));Problem I am having is the code seems to follow the equation as given but the result it outputs is not correct at all.
I have just started coding my Computing project for my A-Level, and I will admit, I am far more experienced in VB6 than VB.NET (as embarrassing as that is to say).I get extra marks for making everything presentable, so was wondering if it was possible to add icons into .NET buttons. For example if I have a button to add an entry to the database, I want a nice Web 2.0 looking icon (for which I already have) next to the text on that button.
I have a server that runs a thread that computes some data through function X. Then I have a client that communicates with the server and gets results from function Y. Now, both function (X and Y) share a common variable lets say varZ. When function X populates varZ when the thread starts on the server, the results are not propagated on function Y when accessed by the client through Remoting. But on the server side the results are correct in function Y! It's almost like when client calls function Y, it has no idea what is happening varZ is as far as the value set by function X thread in the server.
trying to understand DataGridView. I can sum columns with no problems and place the result in a textbox. My problem is multipling two column rows and saving it. I receive the following error when I go to save it. "Column mapping from source column failed because the data column is a computed column. So can I compute two column row to a third and save it, if so how. My code is below:

I have an assignment to create a website that people can use to make dinner reservations. We are using Visual Basic code for the forms. It's supposed to keep running totals of each type of dinner. I'm having trouble getting the running totals to not reset to zero. I have them declared outside of the button click event. Not sure where I went wrong. Here's the code:

I have 10 Numericupdown boxes in my Form from numericupdown1 to numericupdown10. I would like to instantly display the total amount of all ten numericupdown in a Textbox (textbox1) on the form. I don't want to have to push a button to get the total value of the numericupdown boxes.
I have yet another question. I have set up a series of radioButtons to create a menu of choice for a class project and am trying to set it up so that there would hypothetically be a discount on a purchase of two or more t-shirts, I have the coding set up so that if any one item is checked and the calculate button is clicked, then the dollar value or "total" will show up, however I am not able to set up a total for more that one item, it clears the previous "total" and sets up a new total for the most recent t-shirt value checked.
Can anyone possibly take a look at my code (below) and tell me what I'm doing wrong? I have been sitting here for hours trying to figure it out. I'm very new at this and I'm thoroughly confused. I am using a book for Visual Studio "Programming in Visual Basic" and I have gone through all of the tutorials and code examples and followed them exactly (at least as far as I can tell). However, whenever I run the program, I am not getting the sum of the quantities I assigned to the constants showing up in"AccessoriesTxtBx" as I'm trying to. It shows up as $0.00 even when I have checked the boxes.[code]
An ADOX (Access) database has five columns. ID, Date, Category, Store, Amount paid.It is possible to specify ten different items in the Category column: Apples, Oranges, etc.
I am very new to Visual basic. I don't know if I even have everything in the correct order. Here's my problem. I am trying to take user input on 3 input boxes, get discount from select case and then calculate out the following. My problem is I can get the code to do a simple addition, but If I try to do any calculation at all calling the discount I get an error where the output totals to zero. I don't know if I am missing something associated with the sub getDiscount() or if there is a problem elsewhere.Ultimately this is what I want my calculation to end up as.
First calculation Price * Entered Input * Discount = Full Discount Value Second Calculation Price * Entered Value - Full Discount Value = Total
I've been working on a class project for quite a while, and I have not been able to figure out this step on my own. What I'm trying to do is connect the totals from three forms to a fourth page where I can then tally to those totals and then add 7% sales tax on the final total on the last page (I don't think I'll have a problem with the final part of add the 7% sales tax, but I'm not completely certain how to go about moving the totals through to that final form. Also, some of my forms use radiobuttons and one uses checkmark controls. I'm going to show some of the code that I have for each page in case this will make a difference. I think I need to do something with a public variable, but I'm not sure how to title that variable, and the public variable should have sub variable sections in each form, or if one specific public variable should be placed at the beginning of each form.I had also considering using a module to connect the totals in the forms together, because someone had suggested this, but I am not familiar at all with this method.

this place looks pretty reliable and helpful so i thought i'd give it a shot.anyway, i'm a student looking for help. i have to write a program that calculates costs for a catering company. i have that part down, but whats stumping me is that i have to make a summary button that adds everything up into a grand total from the previous calculations and display it in a message box. displaying and calculations aren't really my issues, but getting the data to calculate is.
i have an idea of what to do i just don't know how to go about it. i know i have to store the data somewhere, but i dont' know how to keep adding it up so i can get a grand total, so i'm thinkin there needs to be something there to count.
I need to create an console application that computes the average monthly rainfall, number of months with above average rainfall, and the number of months with below average rainfall, given the rainfall amounts for each month in a particular year. The program must read in and store in an array the monthly rainfall amounts entered by the user one by one.
So far this is what I have got Const intMonths As Integer = 11 'Constant Month variable Dim sngRainfall(intMonths) As Single 'Rain for the month Dim intCount As Integer ' Loop Counter Dim sngTotalRainfall, sngAvgRainfall As Single 'Total and Average Rainfall [Code] .....
How to set this up properly and I am having a real hard time figuring out how to make the data go from this loop to another and add the data to the total.
Everything in my program is working correctly so far. The only problem I have is trying to update my totals for the program. I need to show total sales, total pay, and total commission for the program by using the file and then summary key. How the program works is that you get a base pay of $250 and you get a commission rate of .15 if you reach 1000 sales. I have done running totals before but not for one with multiple functions.
