View 1 RepliesEssentially my program asks the user for their name and a number, and it stores both values in a text file. However, when retrieving the code from a particular line it cannot separate the number from the person's name.will I have to use a new line for every entry, or is there some way to tell my program to differentiate between columns in the code?

How to change the font color of the column header text in my datagridview if the entire column is read-only. I basically use a loop to add columns to my datagridview and then set the properties of the columns. But for some reason setting the DefaultCellStyle.ForeColor and HeaderCell.Style.ForeColor properties does not work. The header text is still black.[code]...
View 3 RepliesThis is probably a simple process but I can't seem to accomplish it for the life of me. What I'm trying to do is transfer user inputted data from a Visual Basic text box into an Access database. The database consists of only one table with three fields: First Name, Last Name, and ID Number (auto-increment primary key). The VB code I have so far is this:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I am trying to import a text file to an access database in VB2008 express. The text file I am testing with is a csv file with 34,000 records. The problem is this takes 2 minutes to read through all this and write it to the database. The actual text file I will be using in production has over 800,000 records and this will take a ridiculous amount of time. I think I am doing something wrong. I have posted my code below. I am reading a record, parsing out the fields to an array, then creating an SQL statement to insert the record and executing it.
reader = New IO.StreamReader(fname)
Do While reader.Peek() >= 0
linesread = linesread + 1

I need to add N1,N2...Nn to the left hand site of the lines in my text file.
I have string which is:
document1.txtdocument2.txtdocument3.txt
What I would like to do is split it so it shows in a listbox as
document1.txt
document2.txt
document3.txt
I have come up with a solution which may work. Its preety over complicated too me but this is the only way I could think of?
What I need help on is a code so that after every ".txt" it will place a "/" so the string will look like this:
document1.txt/document2.txt/document3.txt/
Then I would use this code to split the string:
Dim I3() As String
I3 = I.Split("/")
For g = 0 To I3.Length - 1
ListBox1.Items.Add(I3(g))
Next
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)?
View 7 RepliesI'd like to open a text file and not allow any other processes to write to it. I understand I can do this with the following FileStream:Dim fs As New FileStream(_FilePath, FileMode.Open, FileAccess.ReadWrite, FileShare.Read)
Once I have access like this I need to read all of the lines (I will use a StreamReader(fs)) and then I will need to write to the file (I will use a StreamWriter(fs)).
The problem here is that the StreamWriter won't allow me to set the append mode to false (so I can overwrite all text in the file) when I use the filestream as a parameter instead of the file path. So all text written with the StreamWriter is appended onto the text which I don't want. If I use a StreamWriter with the file path (which will let me set append to false) as the parameter instead of the filestream it will be locked out because of the FileStream FileShare. How can I still have exclusive access to read and write to the file but still be able to overwrite the existing text (append mode false)?

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?
