I have some code here that connects to my Mysql database. It checks your username and password and if your login was successful and it retrieves the phone number under that account. How would the SQL Query look like for retrieving the phone number once connected? Then how would I be able to display that phone number on a label?
I'm making a game that I'm connecting mysql to it. I have a labels that display stuff. Such as your username,level,gold. I'd like to know how I would make the label display that information. For each label a different one. Like on label is their level. One is their username. So on and so forth.
Column names are : ID = username Level = Level Gold = gold
I am creating a game where i have made a login form thats uses the mysql database for the user accounts.The database stores account's login info, level, XP, Coins.
I have a label printer (Argox 1000-x) and i want to print some datas on it. And this printer is connected to my computer via the COM1 port. I can open/write COM1. And when i send some data to printer through COM1, Label Printer's Ready Signal Led will be ON/OFF. But it does not print anything or any label..
I 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?
So I have a text box in a form. The test box needs to take the value entered and insert it into a column within a row in MySQL. I know it's connecting to the MySQL online, I have a message box telling me so upon a successful connection. I'm just having problems adding the value. Here's my code: Public Class frmOptions Dim ServerString As String = "server=db4free.net; Port =3306; user id=dailylogmain; password=XXXXXXX; database=dailylogmain;" Dim SQLConnection As MySqlConnection = New MySqlConnection
Private Sub frmOptions_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I use to do programs in VB5 and haven't touch VB for years, and now i just started to pick it up again, VB2010. my problem is getting data from my MySQL Server (local)
i was able to create my Data Source successfully.. however, when i click and drag my CUSTOMERS table to my form the datagridview shows nothing. I read a few online tutorials and they all said that's all i have to do not working for me..i have 9 records in the table already but nothing is showing..
I have for ex. 5 names i table A in table B i have several rows with 50 names.. But i only want to pull out the records that matches the 5 names in table A! I never know the amount of names in table A so i need to pull out every record in that table..I guess i have to get the names from table A and put them into an array and then in the query get the records from table B that contains the data in the array.. I have tried, but no luck..

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click Dim conn As ADODB.Connection
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.
I have a problem inserting data into a table on a MySQL database using a VB.NET application. I have a simple form where when I set some data to the textboxes and I press a GO button, the code should execute a function called InsertCar() that takes all these values and insert them into the database and then return true if the transaction is done successfully or false otherwise. My problem is that nothing is being inserted into the table.

I wish to develop a client-server application in VB.NET. I want to store some fields in Unicode. As per MySQL documentation I tried the fields with varchar and charset UTF-8 for storing Unicode data.I could insert data using the MySQL connector command object but when I try to display data in datagridview some junk is appearing.
I have worked out how to get the MySql data into the dataset:Dim DataSet_1 as New DataSet()
Dim SQL_Cmd_1 as New MySqlCommand("Select * from Table where feild = X") Dim SQL _Dat_Adapter_1 as New MySqlDataAdapter (SQL_CMD_1) SQL_Cmd_1.Connection = New MySqlConnection("server=localhost;user id=user;password=pwd;database=db") SQL_Cmd_1.Connection.Open() 'MessageBox.Show("Connection Opened Successfully") SQL_Dat_Adapter_1.Fill(DataSet_1) SQL_Cmd_1.Connection.Close()
If the query returns 8 column values and I want to read those values into 8 feilds on a windows form - How do I do it?
my simple program flows like this: a textbox where in you will input a keyword then when you press the 'go' button the data in the mysql database will be shown in the listview. im using mysql and vb .net.i've made the table with sample records in it, the problem is i don't know how to call it to the listview
My database name is "plant3", i have a table named "itemlist" which has a field named "itemname", "task", and "status". I want to show the itemname on combobox and when user choice an itemname the program will show all task and status for that item.
Basically I'm using the following code to access a php file I created that creates an XML formatted page.
xmlFile = XmlReader.Create("http://www.serysoft.com/webservice.php", New XmlReaderSettings())
The purpose of webservice.php is simply to access my MySQL DB and put the relevant data in tags. Then I use:
Dim ds As New DataSet ds.ReadXml(xmlFile) vi.user_version = currentVersion
[Code]....
To stick the information in a dataset then read that information into a Public Structure I have created. This is all contained inside a DLL which is being referenced by my main program.
The issue I'm having is that in the SQL DB, the "notes" field is a BLOB. I have information that needs to retain line feeds. However, when put into the XML format, it loses the line feeds and becomes one line.
Do I need to talk to someone about PHP to get this done? Or is there some known way to handle such a thing as far as XML goes?
