VS 2008 - Read A Flat File And Insert The Records Into SQL Database - Streamreader Necessary?
Dec 29, 2010
I am looking at Visual Basic 2008 Step By Step. I need to read a flat file and insert the records into my SQL database. My code so far:
[Code]...
The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?

So I made an irc client that connects, sends commands, joins a channel etc perfectly. But I can't figure out how to use streamreader to read the data that the server is saying to me, or actually read what others are saying in channel.By the way, I used TCP client.

I'm in the process of making 2 database applications. Each are encountering their own set of errors. For this particular application, I have a "Main Menu" form that has a button which loads an "Add Record" form. The user is suppose to be able to insert new records here via text boxes, but the problem is that record with the first primary key is being displayed in the text boxes when the "Add Record" form loads. I have no idea and can't find anything anywhere about making these boxes blank. I'm connecting to the .accdb through a dataset.

I am trying to Insert/Delete records in a MSSQL database based on if a checkbox is checked or unchecked. The checkbox is an item template in a datagrid, I can check/uncheck the checkbox but it doesn't do an insert or delete. Here is my code:

But then I get the error that the control chkmap has not been declared. I am confused as to how this needs to be declared, do I set a variable to the FindControl("chkmap") and then set it as variable.checked = true ?

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?
Dim connString As String = "Data Source=" & pDataBase
conn = New SqlCeConnection(connString)

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.

I am writing an application that does a number of different things with data downloaded from hardware which is monitoring the power used in my home and produced by my PV Solar array. I have run into a roadblock early on, because I cannot seem to get new data into an Access database that I have linked to my application by means of a DataSet. I have checked the DataAdapter's InsertCommand, DeleteCommand, and UpdateCommand definitions (created by the DataSet Wizard), and they seem to make sense, and nothing is throwing exceptions or otherwise making VB complain, but new rows added to the dataset are not being added to the database.

I have many text files in a folder. What I can do now is to read through one text at a time and insert it into the database. My little app reads a text file when I debug it. So, I need to run it several times to read all those text files and import them into the database.
My question is how to read multiple text files inside a folder at a time. Here's my code which works fine but it reads only one text files at a time.
Private Sub btnRead_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRead.Click
Dim filelocation As String filelocation = "F: xtfilesch25.txt" Dim chid As Integer chid = 25 'read from file Dim MyStream As New StreamReader(Path.Combine(Application.StartupPath,

Obviously, I need a way to loop through a folder and check if there's text file. But I cant get it right.

I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?
