MySQL And FTP - MySQL Databases Exists For Saving Values As Strings (text Only)
Sep 22, 2009MySQL 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.

Jun 21, 2012What 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.

Lock Records On SQL?
Sep 25, 2009I have a form and its filled from a VIEW of two tables on SQL server. When its opened i dont want other users opening that customers details from either table.I know SQL itself prevents writes if its opened but i want to stop people opening the record in the first place.[code]...
I then tried writing these values to the db on the form loading but it doesent work - it just sends back NULLs. I tried the same code in the on load event into a button and it works fine there. So im thinking i should do this as a Trigger on SQL itself, but im unsure how i could get the users computername or Windows Login name, or even username from the front end im building.
