code on storing path image and retrieve path into image using mysql database and vb.net/vs 2008. I only know how to make a browse button and get the image into hard disk and display it in picturebox. I'm done with the the problem is how to store the path and retrieve the path into image.
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 want to retrieve image from database mysql in vb by using no id. But why I have error "Unable to cast object of type 'System.Byte[]' to type 'System.Drawing.Image'." This is my codding. I'm using visual basic 2008 and database mysql. picture format BLOB. E.g.[BLOB - 22.1 KiB]

Here is my problem: I need to store HTML in a MySQL database. Afterwards, I need to be able to retrieve the HTML and have it be valid HTML that a browser can render.
How can I store HTML in a MySQL database using .Net? How do I retrieve it afterwards? As this is the design phase, I can create the database any way that is needed.
I had 7 picture box which is for creating my digital clock.At first, i put my 7 image at the desktop and store my image as array to call out when the program is running.So my image path is
Public myImg(7) As Bitmap myImg(0) = New Bitmap("C:UsersDesktop�.png")
Then after i install the program at others desktop.The program cant be run.I think is cause by the file path.Which file path should i put for the image to enable program can run at any desktop.
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]...
we are doing a mini project on creating a photo viewer.we are using vb2010 as front end and microsoft sql server 2005 as backend;we were stuck up with reading and storing the picture and its path into the database!
I have one project and in this project I want to save picture to application path and save the path to database as string and retrieve the image from the application path.Can u give me some idea about it..i am using vb.net as frontend and ms access database
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.
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
Is there a way to use vb .net code to retrieve the path name for a file or database?And then use that path name for the connection of a database, so that way when I put my application on a different computer it will be able to still have access to the database.I'm using Visual Basic .net 2008 express.
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.
i have a problem in inserting the listbox value into mysql database in vb 2008 i.e

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.
how to retrieve an image from database using image URL and insert it in grid view in vb. net ?? thats my data base table i have 3 columns in table image (ID as int , imageName as varchar , imageURL as varchar(max) i want to insert the image in a grid view but when i run this code i only get the last image in my table everytime thats my code:
