If I do the following
FileOpen(f, Application.StartupPath & "data.txt", OpenMode.Input)
While Not EOF(f)
Input(f, t) 'read data line how do I get to keep the leading whitespace

"one"
"two"

I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???
Dim pathdir As String = "C:workingdir est.txt"
If System.IO.File.Exists(pathdir) = True Then
Dim objWriter As New StreamWriter(pathdir)

I have a tab delimited text file as so :
name loan period loan amount
John 5 years 6000
Sarah 5 years 6000
Jane 1 month 100
I'm looking to copy the lines where "loan period" = "5 years" to where "loan period" = "1 month", in order to show the comparison. The new lines would be appended at the end of the resulting file. The ultimate end result I hope to achieve is this :
name loan period loan amount
John 5 years 6000
Sarah 5 years 6000
Jane 1 month 100
John 1 month 100
Sarah 1 month 100

I have a txt document here that have certain word on it per line. How can I show it in different labels. I have 25 labels and have label name as followsword1,word2,word3,word4,word5 and so on up to word25. I want the word 1 label will show the first line of the text file and the second word2(label name) will show the second line of the textfile and so on up to the 25th line . Can it be done using loop?I tried but I dont know exactly how readline process works to identify certain lines you want to read and also I tried using the "i" variable to auto generate the name of my label but it did not work.

I have two text files and each text file has various columns (each column is separated by a tab " "), now some of the fields in column1 text file2 match the fields in column1 text file1. What I'm trying to achieve is to remove every row in text file 1 where the field in column1 matches the field in column 1 textfile 2 - is this possible?I have used some basic coding in the past to remove certain lines, but nothing as complex as this.

linesList.RemoveAt(1)

'December"}

I have a textfile I need to open and I need to put each line into the array. What is the simplest way to add the elements/each line's data into the array while increasing the array as it reads each line? This is blowing my mind right now..I thought about using a counter and then redim-ing the array (while preserving of course).

I set the time and date, it writes it to a text document then it reads it from the text document back into another textbox that is hidden and compares it to label1.text which is my system time and date.the problem is, I have it so that I can add multiple dates in one document so when I enter one it'll do as so [code]how can I make the program read 1 line, wait for it to match the label, (I already make it display a message box) and then after that is all done, go to the next line and wait for it to match. etc etc.

address may be 1 one or more lines, city state zip should be located just below.
I already have the field set to can grow, however the spacing is the issue. How do I make the spacing adjust at runtime depending on the number of lines in the field. I can space it to say 3 lines, but if the address filed is only 1 line it leaves a 3 line gap.

I can retreive all items in my notepad but when I am adding them up in my listbox, and trying to print them in the console. I can only display two strings. I don't know why. My string is a combination of a name, space & score. ex: "luke 300". That is the pattern of all strings per line in my text file. I am separating the name and the score using space as the indicator. When ever a space is found, string before and after the space is retrieved and added to the listbox
Here is my

I am trying to open a text delimited database using the jet.OLEDB.4.0 driver. My connection string is as shown here:
Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=" & dataDir & ";
Extended Properties=""text;FMT=Delimited( )"";"
I have read that you either need to alter the registry, or to add a schema.ini file containing information about the delimiter in order to recognize the delimiter. My question is if there is any way to do this without altering the registry or adding a schema.ini file, as both of these are unfortunately not an option. The only solution I currently see is to split each row, is this the only way out.

Then the semicolon is not presented in the listbox and I don't have any alignment per column. As the names of the woods are not equally long the prices and the quantity are not aligned directly below each other...
My questions are:
1) How to add the semicolon in the listbox as seperator of the columns
2) How to align the 4 columns in the listbox (as I have an array Item(3) )
Later on I need to be able to change the quantity (last column) from 0 to > 0 (that's why I have to use an array)
