VS 02/03 Populating 2 Dimensional Array?
Dec 17, 2010I am trying to design a little application that allows user to enter daily attendances for 4 weeks.exercise 11, Murachs beginning vb.net) The form consists of a combo box that list the number of weeks, text boxes to enter daily attendances fro mon - fri, a button to save the entries, a button that calculates the average weekly attendance and a button to close the form.
The issue I am having is saving the user entries. I use a 2 dimensional array with 4 rows and 5 columns. Within the click event of the save button I user a for loop to loop through the array and populate each dimension depending on the week selected. Once they are saved I clear the text boxes, set the combo box index to the next position , I.E selecting the next week unless it is week 4 hence the limit has been reached. Finally move the focus to the monday text box.
When I run the code I keep end up with 2 errors depending on how i change the code. The first is that i exceeded the index of the array and the second is that "" cannot be cast to an integer. My code thus far is shown below. I have edited the data so much that I am now just confused.

Populating A Form With An Array Of Controls During Runtime?
Jan 20, 2010I am new to VB 2008 express (I am a 'C' coder but have played with VB6 before). I am writing a simple program that will use the serial port. What I would like to do is, upon some trigger event, open a form, and depending on the amount of serial ports available, populate this form with an array of checkboxes with each check box corresponding to an available serial port. The user could then choose a port which would then determine the PortName.
View 1 RepliesPopulating/comparing Random Integers In Array?
May 17, 2012Basically what I'm trying to do is this, I have 20 statements in a Select Case (right now they're just labels for my own testing), I have a random number generator that will generate a number between 1 and 20. Since I don't want the same statement to repeat during the individual run of the program I'm trying to generate a random number, then check it in a dupeCheck method, then if it isn't a dupe I'm trying to return it to the select case and put it in the array so that when I choose the next random number if it's the same the dupe check method will catch it and return a False boolean and then the random method will do a recursive call to itself to generate a new random number and the whole thing starts again. I'm populating the numbers into the select case just fine, but VB keeps telling me that my functions aren't returning values on all paths, and stepping through I can see that the recursion isn't happening and that it's just sending the repeat number back, but I can't figure out where my major issue is. I'll show you my current skeleton code for the "GuessOrDie" as well as the first manifestation of the code I wrote for it a couple of days ago (the old code had infinite recursive calls and array out of bound exceptions)
I would really love it if you guys could take a look and let me know what mistakes I'm making, I'm having big problems moving from FOR loops in java to For/Each loops in VB and I suspect that is a big part of my problem.
Current Code:

Dim indexCount As Integer

[2005] Populating Textboxes From Array Of Strings?
Jan 22, 2009this is how I set up my data object for a file parser. (
Dim mytable As New List(Of String(,))()
mytable.Add(New String(4, 16) {})
and it loads mytable like this:
mytable(x)(y, i) = sToken(i)
Let me explain the indices, I have a form with a tab control. In mytable,x is the tab number. Each tab has up to 5 groups which is y. Each group has 17 text boxes, i.Each group also has 17 labels.I started looking at Me.controls, and looking at control properties like tabindex for some way to iterate through the textboxes and mytable to load the textboxes.
so I started with:
for x = 0 to 31
msgbox(group1.control(x).text
next x
and I saw how all my objects are not in sequence as it descending halfway through my label controls, then switched to my textboxes, and then seemingly finished randomly. I am at a total loss without the old index property and what I want to do is something like (forgive my syntax)
Form(0).Tab(x).group(y).textbox(i).text = mytable(x)(y, i)
I was thinking of manually setting the tabindex of all textboxes in group1 to sequential order to try something like:
group1.component.tabindex(i).text = mytable(x)(y, i)
To me this is fun and challenging, but also very frustrating and makes me miss coding in assembly As I can't seem to find any reference to the tree structure of accessing components indirectly, if that makes sense.
