what would be the optimum code in VB2010 that check a file to determine:
1) is it a text file, and
2) if it is a text file, does it contain any non-ASCII characters
Note that LF, CR, and EOF would be expected, and should not be flagged. I can think of 3 - 4 ways to do it, but there may be a 'best' way in terms of simplicity and speed.
I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?
I am able to browse to a file and save its path in a textbox, but the slashes from path are removed when saved to the database.

View 3 RepliesI would like to read a text file into an array of strings using System.IO.File.ReadAllLines. However, ReadAllLines strips out some odd characters in the file that I would like to keep, such as chr(187). I've tried some different encoding options, but that doesn't help and I don't see an option for "no encoding."
I can use FileOpen and LineInput to read the file without modification, but this is quite a bit slower. Using FileSystemObject also works properly, but I would rather not use that.
What is the best way to read a text file into an array of strings without modification in .net?
I've done some research into this using the MSD website; I have found that my applicaiton saves the Customer Details to the Customer File, but only as (spaces). No data is present in the file.

I have a text document that contains a bunch of data sets. However before each data set there is a number surrounded by brackets. I need to go instance by instance of brackets and pull the number between the brackets and the lines after the brackets until the next bracket. Here is an example of the text file that contains the data. I know how to read from a text document, do substring, do contain function, etc... I just am extremely stumped on how to do this. Here is an example of a couple entries of the text document...

Notice how different sections have a different amount of lines therefore a reading a fixed number of lines is not an option.
I am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.

I'm using IO.File.ReadAllLines(FileName) to read all lines from text file to array of strings at once. Problem is, text lines include ANSI characters above ASCII value 127 (Scandinavian letters e.g. "Ä" (Ascii 196), "ö" (Ascii 246) and "é" (Ascii 233). Array is build up nicely, but all chars above ascii value 127 are not shown right. How can I use ANSI character set with .ReadAllLines to correct this problem? In VB6 with "Open Filename For Input As #1 / Line Input #1, txtLine" there wasn't any problem.

Basically I am saving text to 2 seperate ini files, also saving the checkbox.checked value so my form can skip the login and auto start. My only problem is when a user saves the information to the INI files after writing them they automatically open up the INI files for display. When the form loads it automatically fills in the fields and if the checkbox is active it checks all the correct details then starts, only problem is it loads the checkbox1.checked ini file then starts the main menu. How can I skip this? and make it not show the ini files everytime they are called upon?
