Store And Retrieve Images In Sql Server Database Using Picturebox?
Apr 22, 2012
store and retrieve image in a SQL Server database with vb.net.:Well, the application in vb.net seems to have a database which can accessed by the LAN computers so the SQL Server 2005 database allows remote computers to share its database once the other computer application requests database from the server.So, every other computer has to store and retrieve images in SQL Server 2005. For example, comp1 has to store images taken into the server and retrieve it like tableadapter.
I am using bindings and tableadapters to store the details in database and retrieving information from db. Please if you have code or anything which is working for me, please post it here... how to store image and retrieve it SQL Server through vb.net provided there's LAN computers who are also sharing the SQL Server database.
SQL Server supports the ability for clients to store objects within tables.Create Field that data type Image and Initialize byte array with a null value initially.Use FileInfo object to get file size.Open FileStream to read file.Use
I have determined thanks to the last q & a that there is something wrong with my "save to db" code as well as my "retrieve to picture" code. Even If I manually save the pic in the db it stil wont retreive. This is code i patched together from 3 or 4 examples around the net.
Dim filename As String = txtName.Text + ".jpg" Dim FileSize As UInt32 Dim ImageStream As System.IO.MemoryStream[code]......
I'm trying to store and retrieve PDF files using SQL server 2008 and Visual Basic 2010.The Issue:i need to lookup a PDF file and store it to the DB using filestream and display it in Adobe Acrobat COM Control on VB Form?
I am using vb.net 2005 and sql server...in vb.net, i was using picturebox.text to capture image from the user.
Am also using Bindings and tableadapters to generate the information from sql server..my server acts as designated server which lots of computers are using my server database...the sql server allows remote computers to share the database i have it in my server.[code]...
At the moment each Company on my website have 1 picture they can add to their profile.I save that image into the database.its their Company Logo.Now i want to allow them to add more pictures. Now i don't know if i must save it all in the database or save it in folders???? Reason why i think folders will be better is because there are so much nice articles with fancy silver light kinda features that i can use but all of them only cater for images saved in folders.And since i am not THAT good its hard for me to change the code to look at the database instead of the examples that uses folders for image retrieval.I would like to add something like this to my website (browsing through the images).Any code examples for me on how to do this when images are saved in the database? I am using ASP.NET with VB.net.
If you have to store and retrieve data from a database is a string not the most effcient way? What is best?
How does this work in a real world scenario.
For example: I have a customer ie first name and last name and the CustomerID is autoincremented when initially added to the database. Now, the user could lookup and find the customer by their ID but we all know that's not practical. They don't know 231223 is John Adams, they know John Adams or Adams John.
So how do you handle this? Access is the database I am using but I think this would apply to any database.
I am trying to retrieve jpg files from access database this is the code I used to insert the jpg picture into the database. I am using vb.net 2010 and access 2010
Dim jpgFile As String = "C:UsersPublicPicturesSample PicturesJellyfish.jpg" Dim o As System.IO.FileStream = New FileStream(jpgFile, FileMode.Open, FileAccess.Read, FileShare.Read) Dim r As System.IO.StreamReader = New StreamReader(o) Try

I have a process that's going to initially generate 3-4 million PDF files, and continue at the rate of 80K/day. They'll be pretty small (50K) each, but what I'm worried about is how to manage the total mass of files I'm generating for easy lookup. Some details:
I'll have some other steps to run once a file have been generated, and there will be a few servers participating, so I'll need to watch for files as they're generated.Once generated, the files will be available though a lookup process I've written. Essentially, I'll need to pull them based on an order number, which is unique per file.At any time, an existing order number may be resubmitted, and the generated file will need to overwrite the original copy.
Originally, I had planned to write these files all to a single directory on a NAS, but I realize this might not be a good idea, since there are millions of them and Windows might not handle a million-file-lookup very gracefully. I'm looking for some advice:
Is a single folder okay? The files will never be listed - they'll only be retrieved using a System.IO.File with a filename I've already determined.If I do a folder, can I watch for new files with a System.IO.DirectoryWatcher, even with that many files, or will it start to become sluggish with that many files?Should they be stored as BLOBs in a SQL Server database instead? Since I'll need to retrieve them by a reference value, maybe this makes more sense.
In my Microsoft access database I have a table called Picture and 3 fields: ID, Name, Image. I was wondering if it was possible to get all the images from the field 'Image' and display them into SlideShowExtender.
i'm using VB.NET 2005 and mySQL server 5.0. Can i ask how do i retrieve the image from database and display images onto picturebox? mySQL column name is pictures then the data type is varchar. and how should i write on the database? eg. abc.jpg?
i have a small database .mdf (sql server database) contains wallpaper table for ex. and a textbox for search. when someone write "wallpaper" in search box, i want to make my form adding Picturebox automatically On the basis of the number of images in the database, i mean i have 1000 image calls "blue wallpaper" in database, i want to see 1000 picturebox in my form and every pictruebox Displays a picture.
I have some BLOB images within a small, 9 row, database and I simply want to run through the database and sequentially place each separate image into 9 picture boxes. I have tried with a picturebox array but it's placing the same image into each picturebox!
I want to load images into a picturebox, save them into a database and display them again in the picturebox. This is the code I'm actually having problem with:
Private Connection As String = _ "Provider=Microsoft.Jet.OLEDB.4.0;" & _ "Data Source=C:UsersclientDocumentsVisual Studio 2008ProjectsSavingsLoansCalc.mdb" rivate Sub UploadButton_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles UploadButton.Click [Code] .....
I'm getting this error message: "Type 'Connection' is not declared" On this line: oConn = New OleDb.OleDbConnection( _ New Connection().getConnectionString)
I'm am having a heck of a time finding a code snippet that works for this. I have got to the point where it appears the picture is stored as a blob (perhaps incorrectly) by using this [code]...

Here is what I'm working with: Dim connstr = "data source=mydatasource;initial catalog=gcs_dw;persist security info=True;user id=myuser;password=mypassword;Asynchronous Processing=True" Dim sqlquery = "SELECT * FROM Customer WHERE CITY = 'Anytown'" Dim connection As SqlConnection = New SqlConnection(connstr) connection.Open() [Code] ..... As you can see, I'm attempting to display the results of the query to the commandline and currently all it is displaying is "System.Data.SqlClient.SqlDataReader". Where are the results of my sql query going and why can't I retrieve them?
