Keep Getting Error When Trying To Connect To Access Database
Jun 23, 2009
I'm using the "Add New Data Source" wizard in Visual Studio 2008 to connect to an Access database ".accdb" but I keep getting an error message when I try to finish the wizard.... "Custom Tool Error: Failed to generate code. 0 is not a valid value for Int32. Input string was not in correct format." this is my first time working with VB in conjunction with MS Access.
I am using VB .Net to connect to an access databse when using several connection sometimes i get this erro "unspecified error microsoft jet database engine" even though i am an administrator on my local machine.
My windows application was written in vb.net and i recently added a web service to it so that I could place the access database in it and connect to it via the web server. I've been succesful in receiving data when doing select statements; however, I'm stuck when trying to do a simple insert statement to it.
I'm trying to create a program that will connect to my access database and perform a simple query. Then I want to put the data (image and other info) into active directory. But I keep getting this "Declaration expected" error when I'm setting up my connection. I'm using Visual Studio Ultimate.
I'm trying to create a simple vb project (using Visual Studio Ultimate) that will connect to my Access Database (the database consists of regular data and jpeg images) on my desktop and perform a simple query. I have looked at multiple tutorials on how to do this but I can't seem to get it to work. For starter, I don't even know what project to select. Usually, I just go with the Windows Forms Application.
I am new in programming an I am trying to connect to an MS Access database. I am getting the following error message when trying to connect to the database; my code is braking under the following line:
I have being working on a code that should connect to the database enter new records,retrive records,read records, update records and delete them as well.
how to connect vb.net 2010 to ms access database to get the data and display it in vb.net application that I am doing right now. My project is that I am doing dictionary application with vb.net so every time i put new word in search box, I want the vb.net to get the definition from ms access and display it in the application.
I have connected the database itself without much issue but i want to be able to edit, add and eventually delete from the database using Visual basic interface. This is for an A Level computing course that i teach, i remember a long time ago when i did the course this was fairly simple to do however i cannot for the life of me figure out how to do it at the moment. This is further confused by office 2007 and VB 2010 both of which didnt exsist the first time i did this.Connect 2010 to an access database?
I have a windows application written in VB.net. After finishing it I'll setup the program in more than one pc. I want to connect the program in all PCs to one database in another PC using Microsoft Access, and I also want to limit the level of access of the users to the database in my program.
Im new to VB.net. Currently im using visual studio 2008 to make a member registration form and i need to save all data into my access database 2007.
Public Class register Dim datatb As New DataTable Dim constr As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\KDE.accdb" Dim sqlstr As String = "SELECT * FROM"
I'm still passed from VB6 to VB2008 and...I found it very changed!I've learned in few days how to use the most used commands, but I've got a big problem in connecting to an Access Database.I saw that we can connect to a database using:
- wizard connection - manual connection
I think that using the Wizard everything is more cleaned and I can reuse the code in a simple way.So I tried the Wizard Connection, but all the guide and tutorial explain the connections using DataGrid. I don't want to show DataGrid. I've learned how to import data in listboxes (also in auto-complete mode) but I cannot understand how to work on data in the way I prefer.
- I've got a combobox with a list of data
- When I "change" the selection (combobox_SelectedIndexChanged) you have to load related data (from another table) in a ListBox (in which I can add other items without inserting them in the DB)
- Send all the data loaded in this fields (there are also other data) to create a record in the DB (like "Order of Product")
i want a code to connect the access database 2007 in vb.net i made login form having 2 fields name & password also made an access database having nameid and pwd as twoolumns,table name is Reg and access database file name is also Reg
I wonder is there another way to connect,edit access database with out using OLEDB command.I want to insert,delete data from access table without using oledb.
I have been using VB6 for many years and have recenty decided to migrate to .net 2008 im slowly getting the hang of it but the problem i face now is the connection string to an access database, below is the code i used in VB6 is there a way to convert it for .net.[code...]
I have this subroutine setup to connect to a MS Access database:
Public Sub MakeDBConnection(ByVal source As String) Try cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & source & ";")
[Code]....
It is in a module, and any function that uses it in the module it works with, however, when I try and use it from Main.vb (my main form) it doesn't seem to do anything, as any tries with executing SQL queries come back with an error saying I must initialize the connection.
I have tried setting all variables it uses to Public, but it doesn't work. Maybe I need to return something? I don't know.
I would like to know how could i connect my Visual Basic program to a database that can be opened to MS Access. My friend made a program that links to a database that opens in MS Access and when you open the database the inputted data are organized to their respective columns and rows. However he used VB6 in making the program and he wont let me see the syntax. And another thing, the program that he made updates the database everytime a new set of data is inputted.
I want to connect to a mdb file but i have never did that before. i don't know where to start. heard something about ado.net and some other things.
the file is a 2003 access file if i am not mistaken. and it is shared on network. so multiple users (not too many, max 50) will use it at same time. what is the best connection to use? i have to mention that i don't want to use data controls. i want to use sql commands to fetch data and manipulate data on the form controls myself. i know there are various connection ways like strings and adapters. not sure which one is better.
Every time I try connecting to an access 2007 database on FTP server, I receive the following error "Your network access was interrupted. To continue, close the database, and then open it again". Actually, I try connecting to the database on the FTP server by setting the value of "Data Source=ftp://anonymouslogin" in the connection string.
