for starters not sure if this is the right place for the post considering that it includes MySQL and VB, its here.I'm trying to load data from one table into a combo box as the data you can select, this i have been able to do "tbl_Wind" using "WindDirID" and "WindDir"
also, I am trying to select (if it exists) a value from "tbl_date" "WindDirID" to select a value from the existing data in the combo box loaded from "tbl_wind"and finally, I want to be able to change the value in the "tbl_Date" depending on if a value is selected in the combo box.when a new record is created in tbl_date it uses default values, so there is always something in the field.below is about how far i got, and its the only part that works (extracted and edited of course to exclude the other queries)

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 RepliesWhat 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

Now I have my databases in .sdf-files. These files are located on a server and loaded into several listviews.
