Store Picture As BLOB In MySQL Database And Retrieve From MySQL Db Directly Into Picturebox ?
Apr 11, 2011
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 have a mySQL table(IMP_SCANS) holding the file, it's name and size for every document:
scan_1 blob
description varchar
filesize int
doc_no varchar
doc_date date
I managed to insert a file to the table. Now I need to save the file to disk.
So I have the code:
Dim conn As New MySqlConnection
Dim cmd As New MySqlCommand
Dim myData As MySqlDataReader
Dim SQL As String
Dim FileSize As UInt32
Dim fs As FileStream
[CODE]............
I all works fine up to the line: myData.GetBytes(myData.GetOrdinal("scan_1"), 0, rawData, 0, filesize) Where it says "Object reference not set to an instance of an object". I cannot figure out why I receive this error.

its been a while since i was here... it's nice to be back... anyway, i was wondering how to upload a jpeg picture to a blob datatype field in MYSQL. i know i could just put the picture path in a varchar type field and just place the picture somewhere locally and retrieve it programatically. but my project does not require me to do so.

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.

We are trying to store and retrieve datatable as blob (varbinary(max)). We convert the existing datatable into an xml file and store that xml file as a blob and while retrieving we get the blob as xml file and convert it back to datatble. It seems to be storing and retrieving the xml object but having issues while converting it back to the datatable ("End of stream - error").

I have a project where the user wants an image stored in a Blob field of a MYSql database. I have been searching for info on the net but so far have not found a good solution for this.In this case the record will already exist in the database and I will need to insert the image into the existing record based on the recordid.Is there a simple way to do this perhaps with a stored procedure and an execute statement. I have very little experience with MySql and little with storing images in a database as well. Most often I will store the images as files and use a pointer in the db record but this user wants it in the db so here we are.

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.

MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

What i have going on, is i have a MySQL connector as a resource on my application, and im basically trying to connect to my MySQL server, to either a) register a new account, or b) check that the account exists and they are premium, and login, Now what i have run into problems with is: My MySQL Database Name has a _ in it which VB is not allowing for some strange reason.
The code i am using is below
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7
