Access 2007 Attachment Visual Studio?
Jan 29, 2012
I'm trying to create a database of all the Magic The Gathering cards I have in inventory and I'd like to have a picture preview of the card in my program. In access I've created a table and for each row I've attached an image of the card. Now I can't get the image to display in Visual Studio. The picture type is the correct format and databindings are all correct. I just can't seem to get the picture to preview as I go down the list in my datagrid.So far I haven't written any code. I've built the application in design view just dragging items from my data sources window.

I have created some tables in 2007 and would like to use visual basic to create an interface for a database. I would like to add, edit, and view my records and maybe create reports.
Does anyone know of any online tutorials which would help me to do this or could anyone offer any guidance.
I look forward to any replies.

I have a table called MEMBER with fields for mem_id, mem_name, mem_addr, mem_city,mem_state, mem_zip and another table called STATE with state_id, state_addr, state_name in Access 2007.On the Visual Studio 2008 form, there is a combo box for the state. The goal here is to display the state abbreviations, but use the state_id value for the mem_state (there is a foreign key between those two fields).The mem_state is defined as number, the state_id is autonumber. Under the mem_state definition in Access, I used the lookup wizard (on the database that is in the bin/debug folder) to set the following properties:
Display Control - combo box,
Row Source Type - Table/Query,
Row Source - SELECT [State].[state_id], [State].[state_abbr] FROM State ORDER BY

I have a class project that supplied me with an Access 2007 DB. When in VB and go through the steps for creating a data source. When the Wizard comes up I click on Database, Next, New Connection, Data Source is Microsoft Access Dagabase File (OLE DB), Browse to Database File Name, Test Connection is successful, click on OK, then Next. A MSVS box appears "The connection selected uses a local data file that is not in the current project. "Would you lie to copy the file to your project and modify the connection?"I am supposed to click NO. When I do I get this "Wizard Form" "An unexpected error has occurred. Error Message: Cound not load type." I need to be able to go to the next part of the Configuration Wizard that says "Choose Your Database Objects" I evensaved the file as Access 2003, and it will not work.

i have create a software for my college which is document management. well am doing good so far up to now where i need to upgrade my database what i mean ?
in case i need to make any changes to my database i don't want to enter the database and create new table or add new fields to existing table to my current database,i would like to do that throught visual studio 2010 programaticaly. something like an additional application where i will choose my database path and the application will upgrade the database with new tables or new fields .
i would like also to ask, in order to create database,or if you already have the database and you like to just open the connection to it programaticaly and add new field ,or relate some table ,you have to work with different librarys? Like ADOX,DAO etc ? and other.?

If I create a windows app which I link to an MS Access databse file that already exists..will I need to have MS Office installed on every computer at which I want to use the app? If not then how do I go about making a standalone windows app that will store information in a database of some form or another ?

I am working on an asp.net project in VS2010 using vb.NET (not VBA) designing an interface to allow a user to upload a file to an access 2007 table attachment field. My understanding is that in order to interface with a table with an attachment field you
must use DAO to connect to the database so that you can expose the attachment field properties. When I try to open the DAO recordset I am getting "COM exception was unhandled by user code" with a message stating "Too few parameters. Expected 3". The error code is -2146825227 and the stacktrace message is "at dao.Database.OpenRecordset(String Name, Object Type, Object Options, Object LockEdit)"

I'm opening this discussion up primarily because I felt that it was inappropriate that Samir Ibrahim and I had hijacked another thread by turning it into a collaborative development thread. This thread will also hopefully serve as a searchable reference for those few who actually make an attempt to search the forum for information before posting a question. For reference the original thread I mentioned is [URL]
This thread is meant to be a repository for our continued collaboration on trying to find a way to update the attachment field using the OLEDB class. Samir believes that he is close to cracking the secret code.:)
Attachment retrieval and updating is a fairly trivial task using the Microsoft Access Database Engine. It is also fairly trival to retrieve the attached files using OLEDb as well. The difficulty comes when trying to add or delete an attachment with OLEDB.
The attachment field is actually a record set where each record consists of six fields. One of these fields is the data field that contains the binary file data. According to the documentation, Access will compress certain file. It appears that compression/decompression is handled behind the scenes so to say and what you are present with is sequence of bytes. The data field consists of sequence of header bytes followed by the actual data. The first four bytes define an offset to the start of the data. One thing that we are trying to determine is the meaning of other bytes in the header.
I have uploaded a sample project at: [URL]
This project is by no means a finished product. It is hard code to retrieve the first record from the included Access database.

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'm a software developer and use visual basic 2005 and access 2007.Well first programmed with Visual Basic 6 but I decided to switch to. Net and indeed it is a big step.
Finally, in vb6 did not need the database linked to software to generate reports because it filled from a listview as the connection to the database do it for DAO ("C: ProSoft Billiard Data.mdb"). Now the question is as I can if I have to file a report so the connection in my software? is a bit urgent as I have to give and software and I need to do the reports.

i seem to have a problem when i try to update a certain record in an Access 2007 Database. I have a small Access 2007 database with 1 table which has 3 Columns and several records. The 3 columns are RecordNumber (Primary Key and it is autonumber), FirstName(text) and LastName(text). What i am trying to do in VB 2008 is implement a search form which when you find a record you can update it. I do not have any problems with the search, but i cannot seem to edit any other record than the first one. For example i search for John which exists, if that record is the 3rd record when i try to edit it whatever changes i make (for example change that to James), the changes i make are made to the first record and not the current one. I tried a lot of things but nothing works, here is my code:

I am making a scheduling application. I have a client table, an employee table, and tables sunday-saturday. the client table has clientID for it's primary key as well as their personal info. the same is true for the employee table, except employeeID andemployee info.The weekday tables have dayID for the primary key as well as clientID and employeeID as foreign keys. The weekday tables also have time fields to record client and employee timesWhen i add my db as a datasource everything works fine, except when i add a new record, type something in the weekday table, and then navigate away from the newly added time record, the data entered is cleared. oddly enough, this does not happen with theclient table when i navigate away. furthermore, this is a new issue that just started happening. I have not touched any code. i just really dont want the user to have to click the binding navigator save button every time they navigate away from the current

Now we see that it has grown to a size where we would like to convert to standalone program because of Access licensing demand. I have been in contact with MS about Visual Studio and gotten a price for 300pr license of VS.I also had some technical questions about VS, but there MS have a technical customer support which are to expensive to have some presale question

I am new to Visual Studio and (I am using Visual Studio 2005)I know how to connect/edit, etc to an access database by just using coding but I am having a problem with the Visual Studio Database wizard.
When I create a new Data Source and I specify a Microsoft Access Database File (OLE DB) connection + *.mdb filename, etc I am able to drag the table name onto the form and browse the contents of the database when running the application. No problem there.
The problem is when I run the application and adding new records to the database via the form, the new data does not get saved. I run the app (F5) + add new data to the database + save + then close the app. When I rerun the app from Visual Studio (F5), the new data is gone.

I've been googling to find a guide on how to access a database with visual studio.I cant find anything complete or up to date. I should point out that I dont have a great deal of experience with SQL.I'm not really 100% sure where to start. Most of the guides I've found tend to assume your accessing an existing SQL database and I need to set one up from scratch. I'm not sure if I'm even setting SQL server up correctly. point me in the right direction on where to get started. A good, up to date tutorial would be great.
For my purposes the SQL database will only be written to from the local machine but there will also be another machine writing to this database.I'm currently using Visual basic Express 2010 and SQL Server Express 2008 R2, mostly because they are the most recent when I googled it.

I have an Access Database, which I connect to using the Microsoft .Jet OleDB provider in VB from Visual Studio 2008.For some reason, whenever I make any change to the code (so that the project builds again), the data in the database completely disappears. I can only assume this means it's remaking the database every time. Note that it does this every time it builds, not just when I connect to it in the code.In my project, this is the database I connect to with the connection string, but there's also another duplicate of the same database in my Debug directory that changes to match the first database every time.The problem only started when I remade the access file to move some columns around and then reconnected through VS a couple of weeks ago.

I have use datagridview and detailed view to insert data and view data in the Access database. I am now trying to figure out the best way to query the data in the database. I have tried right clicking a table in the database explorer and creating a new query. Everything works and I can view the data but I am unsure how to display this query result in datagridview.
