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.
View 7 RepliesI'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

I am building a VB.net application using VB Express 2008 which connects to a MySQL database. Right now, I am only selecting records, but will be writing code for update / insert. I have installed the MySQL Net Connector, most recent stable build. I have set a reference to it in project references. It makes a connection and reads just fine, no issues there at all.
My problem is this: When exiting the project (via calling "End") I am receiving a null Exception error. Here is the error[code]....

I have a somewhat weird problem with a program i'am writing in VB2005. When I debug the program and start 1 backgroundworker (got 8 different backgroundworkers in the program) in VB2005 nothing goes wrong, but when i'm starting 2 or more backgroundworkers I get an NullReferenceException when trying to read from a MySQL database (withing a few minutes in debugging). This error isn't always in the same backgroundworker, but is always in the same block of code in a backgroundworker (1 of 8). I tried different approaches in getting the results I need, for example with read1.HasRows(), but this also didn't workt... the MySQL table doesn't also seem to be the problem.
Line 8 is where I get the error (read1.Read())... This is a snippet from backgroundworker1, but is also randomly happens in the other 8 backgroundworkers as well... When I'am trying to read te content of read1 is says "Nothing" when the error occures...
