I am importing a txt file containing 4 columns of numbers and storing the values into an array, however occasionly there is a line of text that reqires skipping at the start of the text file. I will probably use a textbox or checkbox to say how many/if any lines sohuld be skipped.
[code]....
I am reading from a textfile. How can I skip a line if it's empty?
Or is it possible to delete at the beginning of ReadAllLines to remove this empy lines.
An empty line would be following:
text1
text2
"empty line"
text3

I know this is a dumb question but im doing ok at programming considering im not in college yet lol but neways[code]...

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.
I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Button 2 deletes the contents of the table and not the table itself (which it does successfully). Last, button 3 is supposed to read the text file and insert each field which is separated by a comma back into the existing table.

I have spent many hours trying to find a solution but can't seem to get it to rewrite the text file back to the table.[code]...

View 5 RepliesI have a large text file that I want to use in my project, that data in the text file has about six items for each location. Now I had thought of importing the text file into a database using Access, but not had a lot of luck making it work. The question is is it better to load the data in the project as a text file then search for the string required or to convert it into a database. (The text file is a list of airports and related data.) Can a text file be converted to a Microsoft compact SQL database?
