I have to store a image file into my Access database.
For that i've used 'OLE Object' datatype for my field. When i convert the image into byte array and tried to insert it, i got an error saying "Syntax error in INSERT INTO statement"
I want to know what datatype should i use in Access 2007 and how to convert the image to byte array in my vb.net code.
My code is...
Dim conn As OleDbConnection = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:DBHROsam.accdb")
Dim cmd As OleDbCommand = New OleDbCommand("INSERT INTO Member (ID,mname,fname,image) VALUES (@ID,@mname,@fname,@image)", conn)
I'm having a problem that I've spent all day researching to try and figure out. It seems that the 'Attachment' type in an Access 2007 DB file is stored as three seperate pieces of data in the one field. If you open up the Relationships view, you can see it in the table itself.
I'm trying to do a simple DVD movie database to keep track of everything I have, and who I've loaned things out to. I'm doing this in part to further my education in VB.NET and to figure out some of the things involved with interacting with databases. I haven't actually written any code yet, read on and you'll understand what's going on.
I've got an Attachment field setup in the database to hold a picture of the movie poster or DVD cover art or something like that to help identify the film, and I named it 'Art' of type 'Attachment' since that will hold an image. Looking at the table in Access I see that 'Art' is broken down into three entries: Art.FileData, Art.FileName, Art.FileType. I'd like to be able to pull the filename and file type and display those on the form, but we'll get to that later.
When I use a drag-n-drop gridview of the database into my blank VB form, the Art field just shows the filename, in my case it's 'screenshot.png' since I just dumped a screen shot in as a test. So, the gridview on the form will see the field and display the filename, which is fine. If I do another Windows form and drag-n-drop a Details View (instead of the grid view), and have the Art field in the table set to a PictureBox (in the Data Sources view, you can highlight a field and then designate it as text or picture or date or whatever), I end up with a blank box instead of my image.
I haven't typed any code into any of the forms at this point. I'm still in the Designer trying to get the layout and stuff the way I want it, afterwhich I'll start adding buttons and methods and such to search for things, print out a nice list of the films in the database (with and without pictures) and be able to sort out a list of who I've loaned things to (like an overdue book list). But so far, by just dragging and dropping from the Data Sources into the form, Studio automatically creates the dataset and bindings and such to read from the database file, and I can see all of my test data *except* for the image in the PictureBox (it's just blank/empty).
So, if you want to see what's happening and sort this out, then you need to do the following:
1. Create an access database with a table, that table having at least one field of type 'Attachment'
2. put a picture/image into that field as a first entry
3. in Studio (or in my case Express), create a new project, which'll have a blank form in it by default
4. create your database connection by using the 'Add new data source...' wizard for your Access DB file
5. from the Data Sources, expand the table views and change the attachemnt field from the default of TextBox to a PictureBox (you may have to Customize the types to get PictureBox to show up)
6. drag and drop that whole table onto your form, which will automatically create form elements to display the data and stuff
7. Run it, you'll see the problem.
I have no idea what I need to look at or edit or change to get this PictureBox to display the image from the database. Like I said before, if I leave the type set to the default of TextBox in the Data Sources view, then the field will display the filename of the file stored in that field of the database. Having not typed any code yet, I have nothing that I've done that I can edit other than the automatically created stuff that Studio did when I dragged the table into the form.
Being completely unfamiliar with how VB.NET wants to talk to a database (SQL server, Access or otherwise) I decided to create this little program to learn how to do it. But I ran into this problem and need a little help. What I'm looking for is what I need to change in the bindingSource or TableAdapter or TableAdapterManager or BindingsNavigator or whatever resource is binding the fields on the form to the entries in the database so that the PictureBox will get the part of my 'Art' field that actually holds the image, not the filename or the type. I don't know how to do that, and that's what I'm trying to learn. What I would like to know is how to both get the image to display in the PicutreBox and pull the filename for that image as well to display beneath it or something in the form.
And before someone starts complaining about writing the whole program for me, I must say this is one element of a large personal project and if you read my entire post here you'll see that there are many other elements that will eventually go with it. I just need some help getting this one thing to work. Multiple web searches and such point to a variety of different approaches, many of which I've tried to implement but nothing has worked. I'd like to do this entirely in .NET with no other dependencies if at all possible, but some of what I've seen so far today suggests using Interop and other things to make this work, but those haven't panned out for me either as of yet. My ultimate goal with this whole program is to have one (albeit probably large) executable file that will encompass the entire program, and to have it all work. After that, then I'll look into things like creating my own modules and DLL's and such to thin it out, but I'm not even close to that point yet.
I have an application that has an Ms Access 2007 DataBase which runns great if access is installed. Is there any code that I can use in vb that I would be able to run access with out installing it.
is there a way in storing image and retrieving images using ms access and display in picture box randomly or just like a slideshow?which slides form left to right?or vice versa..i have some codes here but i does not display.
I am trying to store a .png image inside a database using SQL Server 2008. I have done this just fine using mySQL but for some reason it looks like this when placing it into ms SQL Server:
I am using an Access database and vb.net 2010. I have created a table in the database with columns for title, datein, dateout and roomnymber. In vb.net 2010 I made a distinguished title = combobox, datein and dateout = DateTimePicker. When I click on F5, an error occurs: INSERT INTO Syntax Error in statement. [Code]
I recently came across a problem for image file storage in network.I have developed a desktop application. It runs in network. It has central database system. Users log in from their own computer in the network and do their job.Till now the database actions are going fine no problem. Users shares data from same database server.

Ok, so I`ve been studying a bit of VB lately.. bought a few books and read lot`s of articles and seen hours of instructional videos, and I slightly start to get the hang of a few things.. :) I`ve recently started a fun little project, but I seem to lack a bit of knowledge to reach my goal. I`ll first try to describe my project:
I am using VB 2008, then I noticed that with the Provider.Oledb.12.ACE = database.accdb whatever connection string uses the bin/debug/database.accdb file when I connect my program with a database. Suddenly, a database with the same name appeared on the lets say "WindowsApplication1" folder. Then whenever I try to debug/run, it throws an error saying that it was unable to copy the database from the "WindowsApplication1" folder to the debug folder even though VB 2008 reads through the database from the bin/debug folder. As a result, after I input values when I debug, it resets because VB 2008 copies the database from the "WindowsApplication1" folder.
I am trying to update a element from login table but it not showing any error massageor any thing execution is error free but finally whenever i check the database its notupdated.. i'm using access2007 database with vb 2008
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 trying to connect to a access 2007 database with VB 9 and am having some problems.
I went to Data and then selected add new datasource.
Then I clicked on database and selected Next.
I click on new connection, change the datasource to access database file and then click ok.
It doesn't give me a browser box so I can choose where my access database file is. All it shows me is a connection string label and a text box to the right of it. I tried entering the full path to my accdb file in that connection string box and also just the name of the file itself since it's in the same directory but get the error message "format of the initialization string does not conform to specification starting at index 0."
Also, when I click on test connection, it always says succeeded even though no database has been selected.
I have a little problem with converting data from a datagridview to my access 2007 atabase.t's been some years since the last time I've opened Visual Studio 2008. So, probably it's something easyo do.
This is my code so far: Dim i As Byte = 0 While i <> dgInput.Rows.Count
I just installed a VB application developed using VS 2008. I installed the application on a Windows 7 machine. The application uses a MS Access 2007 database.When I run the application, an exception gets raised:The "Microsoft.ACE.OLEDB.12.0" provider is not registered on the local machine.But I don't seem to have this problem on a Windows 98 machine.
I have an application that uses an *.accdb file as the back-end database. Connecting to and retrieving data from the access file is not an issue and is working quite well. However, as a precaution, I have the application first check to make sure the database file exists in the application's folder while it loads up. As a convenience, if the database file is not found, then the application creates a new (structured, yet empty) database. The creation of the actual *.accdb file and the creation of the tables is complete and is also working well.
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 have been trying for 2 weeks now to get this program to work.I am using VBasic and MS Access 2007 in conjuntion with a software application.the Database has 2 fields
1) Text 2) OLE Object (.jpg)
when I try to preview the data inside the DataSet I can only get the text to come threw, but that isn't the problem...the problem is binding the data to a datasource and displaying the information.I cannot get the database to display the information in FIELD 2
Has anyone succeed to compact an Access 2007 database via VB.net code? The previous methods from JRO don't work anymore and there is no help on msdn on how this could be done for 2007. compacting this database?
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.
Note: I'm using Windows Vista Home Premium SP2 - 32 bit edition
I am a VB.net beginner. I am doing simple program that has database connection with access 2007 and i want to store the data (whatever i enter in the textbox) to the database.I did the connection as per the instruction in the msdn(i.e;datasource/database/ms access/selecting accdb file/draging and dropping the fields of the table to the form from the datasource window)I want the code to store data from vb 2008 to access 2007.
