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.

View 6 RepliesThe coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

I've read around on the forums and I saw some people say to use StreamReader, others say BinaryReader. Well Imma try both and see how it comes out. But I'm kinda stump. I'm trying StreamReader first, and I don't know how I should even do this. This is what I've got:

View 5 RepliesI made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.
Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?
