Data Logging Application That Stores Data In A Table In A MySQL Database?
Dec 18, 2010I 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?

Getting Data From MySQL Database And Editing It?
Sep 27, 2010 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.

Downloading Data From Remote Mysql Database
Dec 21, 2009I'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.

View 7 RepliesCombo Box Event To Select Certain Data From An Access Database?
Nov 30, 2010I am using VB 2008 Express to connect to an Access 2007 database. I have a combo box that is populated by the database. When I used the Access report VBA, I used the AfterUpdate() event to calculate a sum and place the results in a text box. I need to know how to do the same operation in VB 2008 Express using the SelectedIndexChanged event of the combo box.
The combo box is called "cboYearMonth" and is populated by my database, this is working correctly.
The text box that I want the calculated results to appear in is called "ExactPagesTextbox"
I have a query in Access called "JobTypeExact_Query" that contains all the pages that I need. What I need to do is calculate the total number of "Pages" limited to the YEARMONTH selected in the combo box. YEARMONTH is a value in every record in this query.
