I know this is very basic stuff dealing with arrays, I have been messing this for a while and I'm not getting anywhere.I have a file with a list of 20 number 0-100. I am trying to get a text box to display the number of scores above average when a button is clicked.Using the same file I also need a list box to display the number of A's, B's, C's, D's, and F's, when another button is clicked.

I'm doing a game. I have a form I want to display the game scores on and another form I have that calculates the scores. How do I make variables work from the first form on the second?
Lets just call one form frmStats and the other frmMain, do you get what I mean?
Create a program which promps the user to enter an unlimited number of test scores. The program should show the high score and the low score. You should use a loop of your choice within this program. The program should look similar to the one below:
View 3 RepliesBuild a small application that fills a collection (list) with 10 sequential numbers, and then prints the collection(list) in reverse order, skipping every other member, until the entire collection has been displayed. For example, if the collection contained the numbers 1 through 10, they would print as:
10, 8, 6, 4, 2, 9, 7, 5, 3, 1 The print out should be in that order no matter what sequential numbers are in the collection (list). If it were 21 through 30, output would be 30,28,26,24,22,29,27,25,23,21 and so forth.
Note: you must use a collection - do not write down the numbers directly to produce the output. Loops should be employed but the loop control variable should be used as an index or subscript number. Your code should work even if I change the list of sequential numbers to something else. Remember that indexes count from 0 first -- the first item in a collection has index 0, the second item in a collection has index 1, and so forth.
I've got the first part of the problem, getting the numbers in the list box, done with no problem. It's the second part I am struggling with. I cannot get the numbers (I am using 1-10) from the list box to display in reverse order in an adjacent text box.[code]...
I am trying to display the content of the text box according the number of records in the database. When i do it manually it works but when i do it through the "for" loop i am confused. my code is as below
For i = 0 To total_rec
fname1.Text = ds.Tables("roster").Rows(total_rec).Item("FirstName")
lname1.Text = ds.Tables("roster").Rows(total_rec).Item("LastName")
Next
Now i want to change the index of "fname1" some thing like "fname(total_rec)" but it does not work

I need assistance with posting lines from a text file (test scores) into an array. From there, I'll have to average the test scores, find the standard deviation (without using the built in function) and assign grades based on the test scores' deviation. I have already written the code for the user to search and upload a text file. And I should be able to do the standard deviation of the array, if someone can help give me an example of how to send the text file to array and average the lines of the array without using the built in math functions.

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I am trying to run a nested loop; it should call a result from a MDB database. Which it does, when I run the single loop it goes thru all of the entries. But when I try to get a number to display twice it stops on the second entry. Having it display the number twice is just a test to make sure it does work, I am going to modify it after I can prove the loop works. The count on the Message Box is correct, but the number displayed is wrong?I want it to display each number twice and then move on to the next number. [code]

I need the number 7 to be displayed in label 1 so how can I do that?
I don't really need all the code, just a method of doing something.I'm trying to do number #42 on page 496 of the VB 2005 book. I'm able to get each number from each button on the phone to display, but I'm not sure how to go about adding the numbers to the number already on the screen. I can get 1 then a 2, then a 3, etc but not 123.
I believe the method is adding to a string, and I know I have to use concatenation or something.. I just need a push in the right direction.
I have read a text file into a textbox. The text looks like this (small snippet):
N08861 A1 P 0 A2 P 0 A3 P 0
N08862 P 0
N08870 P 0
N08900 P 00000001
What I want to do is to only display certain lines - this depends on the N number shown above.
E.G. I want the text box the display line N5000 upto N6000.
