Add Each Item In An Array To A New TextBox?
Feb 29, 2012
This is my source so far[code]...
At the moment it reads in what I have in a text file, splits it up based on where commas are placed and puts the split data into an array, i.e. if the text file is a,b,c it will split up the 3 characters and put them into an array.
What I want to know is, is it possible to write each item from the array into a new TextBox - in the same way that It adds 1 to the 'i' variable each time, except with each new item the TextBox it uses goes up by one, i.e. 'a' in TextBox1, then 'b' in Textbox2

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

I wanted to simply on click a button to add those newly created textboxes to an array of textboxes. Starting with those labeled "Address". But I am finding this very difficult. I am able to add those originally on the form into the array very easily. But am unable to add the newly created textboxes into the array.
Here is my code so far below.

I have a lot of control array textboxes called txt(1) to txt(320) on form2. I have a textbox1 on form1 with a click evet that says textbox1.text= form2.txt(1).text but it gives an error (txt is not a member of form2). I tried disabling option explicit, option strick and option infer. Still won't work. My code is to long for this place maybe a short version osf the code. Do I need to make a Public MyArray(15,15,15,15) as string, in the Module1 then copy txt(n).text to the array or is there a way to access txt(n).

I have an app that I am developing to keep track of my members' names and phone #'s. I have all current names and numbers in a csv file and they are read into a structured array. The app can add, delete, and modify members. I have everything coded except the 'Modify' menu item. The list box is populated with only names at run time, I would like to have both the name and phone number displayed in the two text boxes I have on the form when a name is selected from the list box. I can get the name to display in the text box I have for names, but since the phone number is not in the list box I am wondering how I can get it into the appropriate phone text box. I used txtName.Text = lstMemberList.SelectedItem to get the name displayed but since the phone number is not in the lstMemberList list box I cannot figure out how to get it into the txtPhone text box.

I'm loading a file into an ArrayList, then looping through the ArrayList and each time adding a DataRow to a Datatable, then using the Datatable as the DataSource for a GridView. My problem though is that the file has one field at the end that I don't want to display. I'm not sure though how to not to add it as a DataRow or what to do so that it won't be displayed. Do you know what I might do. This is my

How do I remove an item from an array at a specified index? This code copy's the index and then adds the indexes until it gets to the one you want to remove, skip it, and try to continue. But I get so many errors. From being out of the bounds of the array, to just being null for some odd reason. [Code]

I have a function that is suppost to take a list of strings then split up each part. This is my code
For i As Integer = 1 To UPdata.Count
If InStr(UPdata(i), "!!") Then
Dim DataTBP() As String
Do
DataTBP = UPdata(i).Split("!!")
[Code] .....
One section of UPdata would look something like
ABC#DEF@GHIHSJD!!143#ISJ@PSIODH!!
What I want it to do is firstly separate the lines using !! so i would be left with
ABC#DEF@GHIHSJD
143#ISJ@PSIODH
That part works fine and I am left with an array DataTBP() with 2 values. The strings found above. Its then suppose to extract the part before # for every string left in DataTBP (In my example two) but the function that's meant to do this:
For j As Integer = 0 To UBound(DataTBP)
Dim DataType As String = DataTBP(j)
DataType = DataType.Split("#")
Select Case DataTBP(j)
[Code] .....
Throws me the error
Value of type '1-dimensional array of String' cannot be converted to 'String'.
But I don't know why as DataTBP(j) is a string not an array but a string. I've also tried
For Each a As String In DataTBP
Dim DataType As String = a.Split("#")
Next
It throws the same error

I'm using Streamwriter/Streamreader for the first time in this project and keep getting an "Argument out of Range Exception was unhandled" error.It says "length cannot be less than zero. Parameter name: length."This happens at "dblYearly Income." Also, how do I find out the number of occurrences of an item in an array? For instance, I have a Race combobox and need to find out how many occurrences there are for each race.Also, is there a way to count the number of occurrences of an array itself, I guess the upper index value?

I have an array called linedistancearray.I am now trying to find the smallest integer in that array and store it another variable called mindistance..The following is my initial idea: I sort the array and then pick the integer with index 0. Array.Sort(linedistancearray)However what I get is the first item being a 0 not the smallest integer value in the array I need. HOWEVER if I choose the index 1 it works.So what I was thinking was a way to remove all 0s in the array. I am not concerned about the order of the items at all all I am looking for is the smallest integer in the array.
