I would like to develop a very simple question-answer program whereby there is a user form with a label which contains the question, a text box where the user enters the answer and a button that the user clicks to change to the next question. This should be rather simple but I would like to have about 500 questions in the end (will be slowly adding more questions).

I need to set up a small program/script that can test simple web functionality.I already have a window that automatically load the right URL. What I need now is pointers to how I can make that program return a code if it can load the site, then automatically log in to the site and return a code if it is able or not to log in. Then log out, wait for five minutes and then refresh the site and run again.

Simple Calculator multiplication and division Trying to make a simple calculator. My program inputs numbers and arithmetic operations thru commandbuttons. The numbers, num(n-+1), are odd and the operations, op(n), are even. The code is based on the even op string. Every time a op occurs it is stored in numop(n) to be accessed later. I have all the other operations in sequential order: "*"," "/, "+" and "-". The other similar For-Next loop are the same just interchange the two * for /, +and -. The "+" and "-" work fine in this configuration.
My problem is the multiplication and division does not occur. The numbers and operations line up. The numop(m)=g*h should yield numop(m)=num(1)*num(3). Is there some sort of code to be inserted to accomplish these multiplication and division operations?

I have a form with 10 math questions. Beside each question there will appear a check mark if it is right and a X if its wrong. I also have a label that will display a score in percentage. If 2 are right then it will display 20%. If they are all right then it displays 100%. My problem is ...how can I code the event. I thought of case select, but that would mean 100 cases to make it work.( If check1 and check2 are visible then display 20%, but if its check1 and check 7? Thats alot) What I want ot know if there is an easier or shoter way to ontain the same result. I am working with Visual Basic 2008.

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

x = 4.2 - 0.1
vb.net gives 4.1000000000000005
python gives 4.1000000000000005
Excel gives 4.1
Google calc gives 4.1
What is the reason this happens?

I am missing something simple. I know how to bind asp.net datagrids and webforms, but this is my first time trying to bind to an object list of T in a windows form. (I am use to using datasets with datatables and im trying to get away from doing that).I have a simple object list that gets populated on the form load. However if I click a button to add a dummy record the datagridview does not display the new record added. The bindingNavigator (if clicked nextrecord) and "debug stops" all show that the new record I just added to the object list is there.
Even adding the datasource object in the watch list shows the new records are there. They are just not displaying.
I cannot seem to figure out as to why the new record is not being displayed in the datagridview when I can see the record got clearly added to the datasource.

I created a simple test with SendKeys, and tried both SendWait and Send.[code]I tested in skype, and a few of the letters doubled. I tested in Flash, I got "Iffff yyouu cccaaaannn rrreaaaddd thhhiiisss,,, iiittt wwwooorrrrkkks."Clearly the issue is caused by lag. What can I do to prevent doubling (or tripling) of letters?

I'd like to write a simple Windows form that will make it easy to record a voice message before uploading it to a remote web server and sending the URL to the recipient(s):
[URL]
Currently, the user has to use Sound Record to record the message, use an FTP client to upload it to a web server, and finally, use an e-mail client to send the URL. I'd like to combine those three features into one.

well i am having a couple of issues with this particular homework problem and this is my first programming class so there is probably quite a few mistakes well the homework problem is to take three double values entered by a user and display the largest and smallest using math.max and math.min and display the smallest and largest so i thought i could use a listbox and take the values that went to the listbox and assign variables to each so i can try to use each variable in the math.max and min but im not making it to far and i actually might be way off

Any hunk of code that loops trough the windows form controls array, and based on top/left to bottom/right, resets the TabIndex property? I've mashed a huge form together and expect my user community to want to move things around, and I don't want to have to fool around with this over and over again.

I ma trying to create a program to calculate my math grade. The way my math teacher explained the grading scale was each test is worth 1 point and each quiz is worth .2 points.
So as an example (add both sides up then divide by both sides)
100 =1
80 = 1
15 = .2
18 = .2
213 divide by 2.4 which equals your grade of 88.75
There are more quizs and tests in the semester and I want the numbers to change with the number of quizs and tests entered. The only problem is I am not sure how to code it. I though I would use IF AND statements but I am not sure where to start.
