VS 2010 Uploading A Picture To Mysql Db Using Blob Datatype
Jul 21, 2011its 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.

Apr 11, 2011I 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"

View 8 RepliesImage Into Blob MySql VB2005
Feb 15, 2010I 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.

Retrieve MySQL Blob - Save The File To Disk
Aug 29, 2010I 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:

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.

View 5 RepliesUploading Picture With Decaptcher.com API?
Dec 29, 2009Yes I have been using your Service for many months.I have always used the API for Vb.net and have always send the captcha by sending an actual url to you. (I use the Webbrowser Control) I'll use for example this:
Dim dr As DecaptcherResult = DecaptAPI.GetCaptchaSolved(Me.WebBrowser1.Document.GetElementById("captcha_image").GetAttribute("src"))
But with the current project that I am working on right now I am having to take a screen shot, then save it to my harddrive.
I know that through your API you allow us to upload the image from our harddrive but I just can't figure out how to use the code. I have tried this but it doesn't work:
Dim dr As DecaptcherResult = DecaptAPI.GetCaptchaSolved("c:1Untitled.jpg") proper code to send the image and get the response.
