How do I convert an arraylist into a string of comma delimited values in vb.net. I have an arraylist with ID values
arr(0)=1
arr(1)=2
arr(2)=3
I want to convert it into a string
Dim str as string=""
str="1,2,3"
If i have two textboxes textbox1 & textbox2 and button1 in my ASP.NET and SQL Server database
Database records are:
ID Date Seats
1 15-Dec-2010 1,2
[code].....
how to make a text conversion like the below pic -
1. the textbox 1 is multiline with an array of comma delimited and tab delimited text.
2. the textbox 2 is one line textbox
3. A,B,C,D,E,F,G is where the position of each string before / after conversion
I need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
sort a comma delimited string to different textboxes.Ex.
111,222,3,44,5555,66
to
Textbox1
Textbox2
Textbox3

"Artist.txt")
Do Until Arts.EndOfStream

what would be the easiest way to open a comma delimited text file - each field is surrounded by quotes - and then analyze this file to find the record with the most fields being used? right now i bring the file into and access db then loop through each record to see if there is any data.

I want to add the contents of a comma delimited text file(PracInfo.txt) into a Dictionary on Form_Load. The contents of the file are as follows:
wlvc,coadmin
mrmd,thadmin
ccoa,oaadmin
bfhl,bfadmin
trty,tradmin
nppp,npadmin
For example, I want the wlvc to be the key and the coadmin to be the corresponding value. The code I have so far goes as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sr As New StreamReader("C:Programming filesPracInfo.txt")
Dim openWith As New Dictionary(Of String, String)
Do While sr.Peek <> -1
strHold = sr.ReadLine()
' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this????
Loop

I need to be able to read common delimited text that the user enters into a text box. For example the text box would look like this:1,200,02,200,04,120,1203,200,120I need to be able to read the lines and put the data into a multi-dimension array with all the first values in column 1, all the second values in column 2, and all the thrid values in column 3.
View 9 RepliesI have a text file, with several lines of comma delimited data. The easy part is that each item fits into the same field, so I can use a 2 dimensional array. I would like to use .net classes to do this, not the old file handling functions I was used to.How can I take the text file and load the data in the text file into a 2 dimensional array.Here is example data in test.txt
1,1,1,2,2,2,1,1,1,3,3,3,4,4
2,3,4,5,1,1,1,2,3,4,5,1,1,1
2,3,4,5,6,1,1,1,1,2,2,3,3,4
So this would go into a (14,3) array.I would like to make sure, that the array is automatically sized to the size of the data also.

I want to load a csv file (A comma delimited text file) into a datatable. I found the OdbcDataAdapter Class which looks perfect, but it says it is supported only in version 1.1 of the .NET Framework.

I've got a variable which contains a string like: dim test as string
test="bjcbhiabab,1,1,50,0,1,telepathie2,1,60,0"

I am back, this time may very well be my last. But I will be using this as a great resource if I ever have to do this for work purposes. So far this is what I have. It works. But it doesn't look like the Lab9 specs and test plan. (Attached as .PDF's) Am I just crazy or is there some formatting that I need to do? reservations.jpg is a screen shot of what the output looks like. The UML diagram and specs.pdf should be what is output? Is that what I read? .PDF's if you want to know what is required** I can not explain it very well. Those documents will show exactly what is expected. What I have going out looks like the .jpg I have shown.

There is way to input comma delimited files:
Using MyReader As New Microsoft.VisualBasic.FileIO.TextFieldParser(currentfile)
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Is there an equivalent way to output a comma delimited file. The approach I used in earlier versions of Visual Basic does not work in .NET.
I have been using:
Printline(1, val1, val2, val3)
In .NET that is not comma delimiting
For now I am hardcoding ... & ", " & ... between variables.
I have spent a long time debugging an application that occasionally goes awry, it ends up that the problem is that the comma delimited text files that I am looping through occasionally inserts a comma within one of the fields.
At any rate, I was loading the text file into Excel to try and spot the error which was of no help, somehow Excel parsed out the field correctly and didn't use that extra comma as a delimiter. Is there any way I can get my application to do the same?
And example field value is: "7-8-ALL (1,2&3)", but of course my split code turns this into two separate array values.
I am relatively new to VB. I was initially using fileopen, writeline, and fileclose to create, write to, and close a comma delimited file. But recently I attended a training course where the instructor mentioned that these old methods will be going away and I should try and use Streamwriter instead. I was successful in converting some of my code to StreamWriter when creating a simple text file using WriteLine.
For example: myStreamWriter.WriteLine(text). But this writes an entire line of text.
I cannot see to find any information on how to create a comma-delimited file using StreamWriter. My old code was something like this: Writeline(filenumber, field1, field2, field3, field4). How to do the same thing with StreamWriter?
I'm attempting to read from a comma delimited file, the values are put into a structure (employeerecords) i want to know how i can access the separate sections of this structure i will provide my code so far, i apologize for the comments I'm making sure i know whats going on, I'm new to this, the code currently just dumps the whole file into a textbox, i would like to be able to access and manipulate the individual fields but i am at a genuine loss.[code]

I recently asked a question about reading a file with Streamreader to variables arrays, but I made it more complicated than need be. Here is the simple version of what I am trying to do:
dim MyNumber(1) as String
strMyFile = 100,200 (I already have this)This is the result that I am trying to make happen:
MyNumber(0)=100
MyNumber(1) =200
I would also like the result to be MyNumber(0), MyNumber(1) as double, but I could do that in a later step. This is almost embarrassing to ask, because it is probably basic stuff.
I am a beginner at this and I am taking classes, however I am having trouble deleting a line from a Comma Delimited .txt file.[code]...
