How do you enter in a code for an overall letter grade from a percentage given? I have a seperate box for the letter grade and a seperate one for a the percentage grade . I have it setup when an overall grade and possible grade is entered into boxes it will give me a grade percent but not a letter grade. How is that added? I am doing this for my course project but dont undersatnd the coding very well. I am just trying to pass the class.

View 1 RepliesI have most of the coding done, but i don't know how to code my hangman program so that when you enter a wrong letter, a picturebox image would appear eachtime. Also i want to put a limit on the amout of guesses you can have. If possible, i would also like a listbox with the letters that you have guessed wrong stored in it.

View 4 RepliesBasically, there are letters in welsh which act as one character e.g. "ch", "ng" and "ll". As you can see by the code, i am trying to do this with "ll" right now.
Dim s As String = Label5.Text 'easy enough to see what i did there.
Dim i As Integer = s.Length 'easy enough to see what i did there.
For i2 = 0 To i - 1 'declare the loop

The problem is that the letter "l" gets read out, instead of the letter "ll". So theres my problem, what i need to do may seem simple to some, but i can't see how something like this would work.
OK, every time the letter a is entered into a textbox, I want it to enter in as a 1 instead. Help?

What did I do wrong below? When I pass the enter key but for somehow the enter key event doesn't get triggered.
CODE:
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

View 3 RepliesI have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)
I know I am missing the obvious. I would like a label to show how many cycles in loop are left.

So I made a simple patform game where the player has to jump quickly while the platforms move to the bottom of the screen, as to not touch the bottom of the screen. But, I need to know how to create a loop to loop the locations of the platform. This means that after twenty or so platforms, the same platforms come up again, so that the player will have an "endless" game. I've declared all the platform's locations relative to the location of the first repeating platform:
