Get Count Of Array Elements
Jan 19, 2012Now I'm VERY new at the reading in a text file and storing into arrays thing and tried for hours last night to figure this out, googling and every possible way of writing the code. However, I don't know what to try next and I'm getting more confused by the minute. I have a text file which I load into my program. This data is stored into 6 arrays, each of which has data that comes from either a combobox, date or text field. What I'm trying to do is to find the count of items in each index of the array.

Public serialports() As Object = New Object() {serial1, serial2, serial3, serial4, serial5}
dComPort = "COM4"[code]....
The above code works fine! But im having trouble trying to now retreive whats stored in the array.In the above example, an entry will be stored in serialports(4), all other array elements will be blank.If I do this it works.
MsgBox(serialports(4).PortName) ' this retuns the value COM4
But I'd like to loop though all array elements and print out ALL the PortNames, The below code doesnt work, I get an error Object variable or With block variable not set.
For i = 0 To serialports.Length - 1
MsgBox(serialports(i).portname)

Adding Elements In Array?
Feb 25, 2009I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK.

My problem is my event is returning zero. Therefore I believe my code is somehow flawed.
My approach is to create functions that calculate the required metrics. I have only tried to code one function to date. If I can get help making one function work, I will be able to do the others .
