View 10 RepliesI have a data logging application that stores data in a table in a MySQL database. Data with a TimeStamp is logged into the table anytime the data from the sensor changes. This means that there maybe 2 seconds between data points or there maybe 20 seconds between points depending on how the data is changing.
When I need the data I have 2 dates and use this command to fill a table..SELECT FROM myTable WHERE timeStamp > date1 AND timeStamp < date2 This gets all the data that has a TimeStamp between the given dates, but in most case the first date in the returned table will be after date1, so I need to get the data from one row before the date returned in the table to know what the data was at date1.How can I get the data row that immediately precedes the returned data set?

well this may be a simple question to some but for me, im not even sure where to start. I have never done a program in VB.NET yet that uses a MySQL database. So this should be a fun thing to learn. I looked at an example for access databases and it seemed pretty straight forward. But I must use MySQL as the database is on a Linux server in Ohio.
What I got so far is how to connect to the database using ADODB. Here the example I'm giving. You got 4 col's call AccountNum (primary key), Phone, Name, and Address. For each row is data of a client. What I'm trying to do: the program asks for the account number. You type in the account number of the client. It then
compares it to the rows of AccountNum col till it finds a row with it. Then it asks if you'd like to change the phone number or address.
So what I'm looking for is the, how to call rows and change data in col's.

View 8 RepliesI'm looking into creating a program which will on program opening connect to a remote mysql database, download the data and store the data into a local file (keeping both in sync is the idea).
Getting a connection to the remote database is my first hurdle, and i'm not suceeding, i know i need to read through more info but if i could get this working it would help me tremendously.
I have attempted to connect using the mysql connector, using the server IP and port number ie. 199.002.999.000:3306 but it doesnt connect, it does connect locally ie. localhost but for some reason it won't connect to the remote server.
My other problem is that i cannot control the mysql server, i.e connections allowed remote etc, i think they're just enabled to accept connections from the server.
Is there a way to run a hidden browser script behind the scenes, download and run the file? I've tried looking for possible ways to acheive this, but have come up trumps so far.
