Per this UserControl that can be added to a blank form, I would like to use the HorizUnits array below to map custom grid x coordinate from a mouse x position.For a given input value 13, what syntax would I use to obtain a value of 2 where 13 lies between Value 10 and 16 for which 2 (Name) would be the custom grid's displayed coordinate position?

Trying to input a high setpoint, low setpoint, a % load, and number of compressors, then calculate the temp that all compressors are off. Then build a datagridview with the staging of compressors from all off to all on for each compressor up to 10 compressors.I am trying to insert headers from 1 to 10 compressors (Variable) with the text "Comp1", "Comp2", etc....Two rows with header. I am trying to use an array with index number to insert the text, but that is where my problem happens."Index was out of range".Here is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer, num1, num2, num3, num4, alloff As Single, stg As Single

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
I had a form with over 40 command buttons on it. I indexed the buttons: Private Sub Command1_Click(Index As Integer) 'perform this End Sub How can I achieve the same basic thing in .net? What is it called? What to search for?

I am coding a program for a movie trivia game that randomly shows a movie quote and the the user selects a movie name from a combo box that matches. I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

View 6 RepliesI have a string array, and I need to get a range out of that, say 10 items counting from index 20.
I see there is an extension method called Take that can take a number of items from the beginning of the array, but I also need to specify the starting index.

24-Mar-2010,3,49,28,5,23,42,41,4,GUINEVERE
and stores it in an array (n-1,6) where n is the number of lottery lines, so the array looks like
0 1 2 3 4 5 6
0 29 18 38 44 14 43 13
1 32 38 11 15 42 6 24
then, in a 1D array I store the player's numbers, simply as
0 23
1 16
2 19
[code]....
I want it to take each number from the player's number array individually and compare them to each row individually in the lotto results array i.e. the first six cells in each row in the results array will be compared with each user number to find any matches, if a value matches then a count is incremented. if the count is greater than 2 but i'm getting no where with it :( i've been trying to use the For To loops but keep getting index out of range, or else nothing is happening at all!
