Error While Writing Into Access File?
Sep 10, 2011
What i've written opens an Access database and one can read and write into it (on a table called Journal)It does indeed work for newly made Access files. However it doesnt work with a specific Microsoft Access database (again .mdb) which was made with a very old Access, like Access 2000 or something.The error message is: Syntax error in INSERT INTO statement.Inside the zipped file below you will find the source code of the program, along with an access file that the program CAN read, and the one access file that i NEED the program to reed but it cannot!
To see what i mean run the program one, try to add a new line to the database. you get an error!now rename the Journal.mdb to "journal.bak.mdb. And the journal_working.mdb to Journal.mdb try to add a new line to the database again without altering the source code at all. it succeeds now!!
NOTE: the program can READ data from both files. but it CANT write data to the old access file
this is the code:
Dim cb As New OleDb.OleDbCommandBuilder(da)
Dim dsNewRow As DataRow
dsNewRow = ds.Tables("AddressBook").NewRow()
dsNewRow.Item(1) = txtFirstName.Text 'or .Item(1) =

I am writing an app in VB2010. My code parses a text file, assigns data to variables My??, and then attempts to store this data in an access 2010 (actually access 2007 format) table. Yet, whenever my code gets to MyRow.Item("Artist") = MyArtist I get an error 5 'Artist' does not belong to Table MyTable, but the field/column does exist in the table as do all the others.
01Dim tbl As DataTable = New DataTable(MyTable)
02tbl.Rows.Add()
03Dim lastRow As Integer = tbl.Rows.Count - 1

I use Visual Basic in Access, and I have no problem writing data directly to a cell in a database table. But I can not figure out how to write the code for Visual Basic 2008. For example I would
use Me![cust_Cost] = 20 to input 20 in the database table.
I have purchased two different Books on Visual Basic 2008 and not one of them show how to input data manually.

I had one semester of vb.net in college and it was lacking at best. I am trying to write a few lines to a file on my desktop. When i implement the program it will actually find a file in a network share but the concept should be the same. I am basically writing a program to combine multiple csv files into a single file. I have the entire program written except combining the files. this is my code so far. it's incomplete but after i can figure this issue out the rest should be pretty easy. i will later on add parameters and all that fun stuff.
Public Sub writeFirstLine()
fileWriter = New System.IO.StreamWriter("cusersmyusernamedesktopforktruckfile.csv") 'the error happens at this line

I have a file already on my desktop with this name. in the actual program i will have to create it or delete it and all that fun stuff but for simplicity at the moment i just need to find the file.
at the moment it gives me an error that says directory not found. it seems to be looking for a file in the project folder instead of on my desktop. how can i get it to look at my computer instead of the file the project is held in?

I am trying to create a countdown to a date that the user can enter. I think I got most of the code in the button that saves the date. It gets the date the user entered in comboboxes, creates a txt file, then writes all the information to that txt file. I tested it out, but it didn't work. It created the file, but when it tried to write to it, it errored. The error says "The process cannot access the file 'C:Countdown.txt' because it is being used by another process." This is the code.
Dim enteredmonth As String = monthcb.SelectedItem
Dim enteredday As String = daycb.SelectedItem

How can I change the delimiter when writing my Access table to a text file? I was hoping it would be as easy as adding a similar option like we do for HDR=No; maybe Delimiter=|
Dim AccessConn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|mydatabase.mdb")
AccessConn.Open()Dim AccessCommand As New System.Data.OleDb.OleDbCommand("SELECT * INTO[Text;HDR=No;DATABASE=" & userPath & "].[" & fileName & "] FROM tblMyTable", AccessConn)
AccessCommand.ExecuteNonQuery()
AccessConn.Close()

I've been doing some more experiments and have summarized the query as below: I've created the simplest application. A project with a plain form, which writes text file within its application directory. Simple as that.Supposing this was my application which I want to distribute on the world web. I've created a basic installer for this using NSIS installer. The Installer installs my application in a folder created inside Program Files. The OS is Windows7 and UAC is enabled.Now I know many people have been facing difficulties in accessing files inside the Program Files folder. My app is simply creating a plain text file, nothing more, and within its own application directory. It is giving Access Denied error. But if I right-click on the EXE and run it as Administrator, then it works ok.The only solution thats available is not to write in the application folder, and write text file in some other folder which is not protected. My question is that other programs that are installed on my system are also doing it. I have a temperature monitoring software called SpeedFan on my system, it creates log files within its app directory. All other softwares create log files within their app directories, why cant I?I just have to make a small log file for my application and Win7+UAC is not letting me do it. I don't want to write the small file in any other folder. How are the other softwares accomplishing this ?

For testing purposes, I write a lot of alerts and error messages into a .txt file (some 15 entries per second). At the end of the day, the txt file becomes very large. I am now getting confronted with data loss in my application (threads indicated as being busy). Could it be that my entries in the Log.txt are slowing down my application to the point that the latter becomes unstable ?

I have some coding which edits my text file and saves two versions, the first version removes all multiple space with one space and saves it as a text file and the second replaces the spaces with a comma and saves it as a csv file. The problem I have is however later on when I run other code using the saved text and csv files, it looks like the processes are in use. I get the following error:
The process cannot access the file 'Path' because it is being used by another process.My actual coding:
Private OpenFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile1.txt")
Private SaveFileName As String = IO.Path.Combine(Application.StartupPath, "TextFile2.txt")
Private SaveFileName2 As String = IO.Path.Combine(Application.StartupPath, "TextFile3.csv")

Im trying to write to a file I created and place "Unregistered" in it. Thought it would be a simple task but keep getting an error. Its happening when I try and open the file to write. This is the error: Access to the path 'G:\Projects\Project\pbss\bin\Debug\5\pbssv\Data.DB' is denied.
Ive tried adding the file attributes to read-write and still get the same. Most of the code ive looked at via a google search points to the same as ive got for the Added default value area. Im not sure if there is a conflict between the 2 different ways im accessing the file when creating and writing too? [Code]

I am currently using the below code to upload a file and display progress. It works fine except there are a few things I would like to do differently.
I am using the main FTP account for my website which has access to all of my files. I set up a different FTP login to use that only has access to a specific folder, but when I try to use it I get: Error 550 No such file or directory or access denied.
This FTP account allows access to: mywebsite.com/upload/users/ only If strFTPAddress = mywebsite.com/upload/users/ I get error 550, I've tried a few other things too and it's told me that it's an invalid URI
Basically what I want to know is if and how I might be able to connect using my second FTP account so that I only have access to the upload/users/ directory.

I cannot figure out how to get past this error. I have 1) Given the user "everyone" access to the entire directory that this dll is contained in 2) Deleted the dll and rebuilt the project 3) Deleted the Temporary ASP.NET files in the Windows Directory 4) Restarted IIS 5) Tried to change to a different user in IIS security including trying ASPNET. we are not using windows authentication. 6) Even copied that dll from other machines.
Here's the error. I have no clue at this point if it's code missing inside it or something else wrong with it or my setup. Other people on my team are using this dll ok. Could not load file or assembly 'Anthem' or one of its dependencies. Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

At my company we build a lot of small, administrative type databases generally used by a dozen or less users. We have thus far done them entirely in Access. I've been doing VB forever and would like to write nicer, rich UI apps using a VB front-end to and Access database instead, as I find Access apps clumsy to use; VB apps look better and have more UI options.
I've started to play around with building Data Sources, Binding Sources, etc. and dropping them on forms, trying to create something useful with as little code as possible. I'm just wondering what folks generally think of using this approach. Remember this is for small, not complicated db apps with few users.
I know in the VB6 world bound controls took some heat for being not worth the effort it saved you.Also, is there a good book on the subject that concentrates on creating VB/Access apps with minimal code?
