Im writing a program where im trying to split some text imported from a textfile into a textbox into an array.The array is undefined and i would like each piece of text to be an element in the array. I would then like to sort this information into alphabetical order.This is the code I have at present; I apologise if any appears to be out of sequence or whatever, VB is a rather puzzling language to myself!
PS i have the code behind a button as you can tell from the code.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim textInput As String
textInput = TextBox1.Text

I am trying to split text in a TextBox and I get this error {"Index was outside the bounds of the array."} while using this code
Dim s As String = Me.RichTextBox2.Text
Dim parts() As String = s.Split(":"c)
Me.TextBox1.Text = (parts(0))
Me.TextBox2.Text = (parts(1)).Trim
I am stock, it will work fine for a couple of reads, since the Me.RichTextBox2.Text text changes constanly but every now and then I get the error
Splitting Strings And Then Displaying In Textbox?

splitting and trimming text file
View 1 RepliesI've got a problem reading in a Tab-Delimited text file. There's an extra tab in one of the fields its reading it thats not a delimiter, and it's throwing off me reading the file into a table. This specific file does have quotations around that field though.
What would be the best way to take that tab out before splitting the row by vbTab?
Im reading each line in the text field like this, splitting on vbTab. X is a string array
text = x(J).Split(vbTab)
Is there any easy method for splitting text in VB.NET? (using a start and end string to grab whats in between?)I do this all the time in JScript with the following:
<junk>
<blah>
<data>someData1</data>
<data>someData2</data>
[Code]...
I need to find the <div>Total</div> index then grab the data between the 1st and 3rd divs after that.
I have I text tab delimited file. in every line of that file at the same position in every row of the file I will have a bit that I would want to compare against 23 values (I will call them criteria). So if on every row the string I need matches one of tjhese values then that row will be written in File1.Txt if that value doesn`t match any of the criteria the whole row will be sent to File2.txt.
So far managed to get the original file written in the same format in a newly created file.
how to get the functionality I described working but am stuck with correct syntax.
Here is what I have so far:
Dim fs As New FileStream("C:Original.txt", FileMode.Open, FileAccess.Read)
RichTextBox1.Text = ""
Dim d As New StreamReader(fs)
[Code]....
Now I will need to declare every single row in RichTextBox1 as String then will have to get the bit I need will have to declare that as well(I will need from every row the string taht is between characters 96 and 104), also where do I keep the 23 criteraia values.
I am exporting a directory list from a FTP directory to a text file, I would like any suggestions how best to read and split the information detailed on each row in the text file as information isn't Tab Delimited (which i have code for if it was) and the number of spaces between each attribute is different. Below is a snippet of the text file, the main two I require is the File Size and the Filename.

I have a large tab delimited text file to process each day (usually around 25 mb) consisting of usually well over 100,000 lines. The file is actually made up of about 9 or 10 reports separated by "END OF REPORT". I'm wanting to write each individual report to it's own text file. Some values may have trailing spaces or even contain nothing but spaces, so I am wanting to trim those to only the data, or be left with null. Ultimately each report will be imported into sql server tables. The code I have below runs successfully to completionwithout error although each text file is empty. The script is also extremely slow and seems to use quite a bit of memory. The arguments are ad
View 1 RepliesIm trying to read a text file line by line and place each line in a separate Combobox. right now with my code i can only get it to print lines in separate message boxes.
The text file (test2.txt) contains

if i replace the MsgBox code with Combobox1.text = (strArr(count)) i get nothing.
I have a delimited text file, let's call it models.txt and it's delimited by a comma with carriage returns.
example:
21,Z920081
22,Z920082
59,Z930023
120,Z930027
I'm trying to input this into an array and then a combo box using:
dim item as integer
dim array() as string
dim ifile as integer
[CODE]............
What I want to do is to display the right part of the delimited text (Z920081, Z920082, etc) in the combo box. But when you select the item in the combo box, I want it to use the left part of the delimited text (21, 22, 59, 120, etc) as a variable for other use.
I have managed to access and read a specific file line by line. If I wanted to split information by a comma or space and then sort alphabetically or numerically, how would I go about this procedure? Would I create a loop within the reading loop to parse the information?

I'm currently making a program that will be used to practice German. It reads from textfiles that have English words (noted by # prefix) and German words (noted by $ prefix). An example of this:
#hello $hallo
#good $gut
#evening $abends
The way it currently works is it loads a text file, finds all # and splits to an array called "English" and finds all $ and splits it to an array called "German" What I want it to now do is feed the "English" entries into textboxes on the left, and "German" onto textboxes on the right so I can then match them out and make a sort of memory game out of it. Unfortunately, I don't know how I would loop an array through multiple textboxes. Conveniently, the textboxes on the left have even numbers, and the ones on the right have odd. Is there a way to possibly find all evenly numbered textboxes and loop "English" array entries into them, and the same for "German"? I've realised this has now gotten a little convoluted, but hopefully somebody understands. I can screenshot the form for better explanation, and copy my existing source code if anybody wants it.
LblPPG.Text = Val(TextBoxPP.Text) / (TextBoxQTY.Text)
This is the only way I know how to obtain the info I need for this equation but if generated again with no input from the textboxes I get an error. Is there anyway to bypass this if its generated a second time with no inputs?
I have a Text file that looks something like this:

So where
"," is, How would I end up splitting them?I tried something like this:
vb
Public Sub ImportList()
With frmOverview
If .ofdImport.ShowDialog = DialogResult.OK Then

But it only ended up splitting the CourseCode ("157548")
