View 1 RepliesI am asked to write a front end program in VB 2005 (that will run in client computers which running on Win XP) to access an existing MySQL database running in Linux. It is not my preferred choice, but the user have the database and server working just as he wants it, and do not wish to change, at the same time I do not wish to change programming language. Is that even possible? Can we actually write VB 2005 programs that will run in client computers complete with NET framework 2.0 to access a Linux operating database?

View 2 RepliesI'm wondering what the best way to render a scene made up of multiple-sized tiles, from back to front, with different heights. [code] Objects are sorted based on not their initial X/Y value, but their X/Y+Height value. That way, objects are rendered based on where they 'touch' the playing field. E.g., X/Y = top of a tree object, X/Y = trunk of the tree object.People (including the player) will be just normal map objects that get rendered and updated within a huge sorted list every frame. Right now, fudging around with my code allows my Player (32x64 pixels) to stand infront of a building but has her feet get overlapped with a patch of grass, which doesn't work. However, changing the sorting algorithm makes the player disappear in the building but you can see her feet.Also, should my players be included with the list of map objects? Granted, these will only be graphical representations of their data stored elsewhere (won't be cleared when map changes), or should I throw them into a whole new rendering list (which might open whole new problems). url...From what he says, he has 4 different layers and then draws the actor between Layer 3 and 4, with layer 4 being objects that will always appear on-top of the person.So, it appears that his player isn't a map object but an actor rendered separately from everything else.

View 3 RepliesI'm looking for a front-end that's very simple, to access a to-be-built MySQL Database. I actually need it for only one table. I was thinking that the user could search in a way that would ask for values for each field of that table, and give the option of leaving it blank. Then, it would return all the entries that match up with the query.

I'm having some trouble setting up a working connection to a mysql database from Visual Studio 2010.After downloading and installing the mysql-net connector, I set up a simple testing database in Xampp and experimented around a bit until I managed to read some values from the database and inserting new ones.I'm trying to access another database on a remote server and all I get is an error message: Unable to connect to any of the specified MySQL hosts.Basically, I'm only trying to execute this code:
Dim con As New MySqlConnection("Server=111.11.111.111;Uid=root;Pwd=mypwd;Database=mydb;")
con.Open()
con.Close()
(server ip looks a bit different of course)When I access my local database, it looks quite similar:
Dim con As New MySqlConnection("Server=127.0.0.1;Uid=root;Pwd=;Database=test;")
con.Open()
con.Close()
Nevertheless, I can access the remote database easily using a simple PHP script... no problems there.

I have developed a frontend app using VB 2010 which is to connect to a remote MySQL server. My server has an internal IP address of 202.56.20.72 and an internal IP address of 192.168.20.44.
When I use the internal IP in my connection string and connect over LAN, the whole thing works fine. But when i changed the IP to the external address and tried to connect to the server over the internet, I get an error something like 'Failed to connect to MySQL server for user 'user'@'localhost', [using Password=NO]. This means that for some reason, it is not connecting to the server at all.
