View 8 RepliesI have a very large text file about 4 million lines that I would like to separate into several small text files based on the strings contained in the first column of the text file. I want to open the large text file, choose the lines that apply, create a new text file with a name that has a number at the end of which will match up with the value in the first column of the text file. I want to then copy the applicable lines to the new small text file, save and close it. I'm not sure how to go about doing this after opening the large text file and using the readline method. What if the folder does not exist? Do we have to create it? I want this procedure to be general, as there could be up to 25 million lines in the text file.

I've been developing a arcade game, and as every good arcade game, it has an incorporated scoreboard so that players can see who scored better. My problem is that everytime it enters a new scoreline, it deletes all the previous lines in the text file. The code I've been using is the following:
If player1 > 25 Then
objReader.Close()
MsgBox("O " + jogador1 + " ganhou.")[code]............
I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?

I am using Visual Studio 2008 on Windows XP SP3. User has Windows 7 Pro (32 bit). The IO code below works for me. The read code works for user, but the write code only works for new files. If the user tries to overwrite a current data file, then no data is written to disk. I have done all the usual IO checking (valid file name, etc.) and have excluded it from my same code. In my app, FileSave and FileSaveAs both call WriteDataFile(FullFileName). Any reasons why FIleSave would work on Windows XP, but not on Windows 7 Pro (32 bit)?
Code:
Public Function ReadDataFile(ByVal FullFileName As String) As Integer
' reads a Data file from disk
'
' Format is a text file, with [TAB] seperators and [CR][LF] as line terminators

View 2 RepliesI am trying to write to a text file....which is fine but thers a but!I want to output date so it is all aligned for example
Name Age
John Smith 35
Danielle Johnston 37
As you can see the above data is not aligned!! VBTab doesn't work as depending on the length of the name the file looks like above I want the text file to look like
Name Age
John Smith 35
Danielle Johnston 37
so everything is aligned!

I'm creating a small vb.net application, and I'm trying trying to write a list of results from a listview to a text file.

I must read the file scan for value T250,T169,T168,T170,T176............which ever value start with T after the line"DETECT,ON". then i must sort these values so that it will be in acending order. Then i must write back that values in same text file after the line FMAT,2.. Now i can read the lines which contain T. Then i store that lines in array. My code shows error when i used sort methode to sort the array which i store in array.

I'm writing an application for my Smartphone (OS is WM6 pro .NET Compact framework 3.5). Up till now i used VB6 so i'm pretty new to VB2008.
The application needs to store a set of items in a text file located on the device and retrieve them back. Since WM 6.0 doesn't support MS Access databases i have to work with the old fashion text files to store and retrieve my data. However since i'm new to VB2008 (and given the limitations of writing a smartphone application) I would llike to know how to write and read data to and from a text file.
