I am making my first windows forms application in VS2010 and I am having trouble with arrays. I have code that dim's an array 'TabSiteInfo(2,20)' as a string. Then, I have a Loop that adds records to the array. The problem is that my array is not filling values from the loop. I know VS2010 handles arrays differently, but I have this same code working fine for me in VS2008 ASP.NET application. Below is a sample of the code.

View 4 RepliesI am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10
In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

and stores it in an array (n-1,6) where n is the number of lottery lines, so the array looks like

then, in a 1D array I store the player's numbers, simply as
0 23
1 16
2 19

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!
