Executing MySQL Queries Through VS2008 Using ODBC
May 2, 2012
I'm developing a small project (just for learning, I'm not a pro) which involves creating software which could be used by a store owner for invoice generation. It involves storing all the store's products in a MySQL 5.5 database. Visual Studio 2008 is used for front end (Project was started in VS2005, later converted). MySQL ODBC Driver 5.1 is used for connection purposes. I'm still a student and haven't been able to learn .NET yet. So, I used the following link to connect the Database and the interface. I'm able to obtain all the data from the database like 'Product Name', 'Price' etc on the VB's forms through labels.
Now, for the purpose of invoice generation, the data in the labels i.e, 'Product Name' and 'Price' should be added to another table named 'Cart' whenever a button named 'Add to Cart' is pressed. How can I implement it? I mean, could anyone provide me with a code snippet that fetches the data being displayed in the labels and adds it to another table through 'INSERT' statement? P.S Basically what I need is a code snippet in VB that lets me execute an SQL query(any one like INSERT or SELECT or UPDATE) when a button is pressed in a form.

I have developed a small ms-access based software with vb.net.
I've added auto-update capabilities to the software (mostly by using clickonce) to simplify the release of new features.
Every version of the software executes the update routine which may update also the existing database.Lately i've made few changes on the database structure adding few stored queries, so i want the autoupdate code to programmatically add these new queries to the existing database and make it perfectly up to date.
I haven't already found a solution to add stored queries to an ms-access database using odbc...I also tried to use the "CREATE PROC" sql statement but it does not seem to work with access databases, even if i create the query form the Microsoft Office Access front-end.I've found some examples that uses ADODB, but i'm using odbc to remain both x86 and x64 compliant.

I'm connecting to my mysql server using ODBC in vb.net, the database is shared throughout the company because it is used in an accounting program (simply accounting), each user has their own account user/pass to login to the database. I have developped a program that uses the accounting database and combines it with other information, my problem is that at least once a day I get this error when I run my program: "(10061) ERROR [HY000] [MySQL][ODBC 3.51 Driver]Can't connect to MySQL server on"and the error persists for at least 4 hours, for some reason it starts to work again later on in the day.

I've written an application and I'm trying to utilise a database behind it. I've created a mysql database, and table which all appears to work correctly. I appear to have connected to the db correctly too. And hit a bit of a brick wall. As a side-note, within Visual studio connected to the database using the add data source wizard, I then dragged and dropped my db table's column onto my form that intends to display them all (6 textboxes, including primary key) and that now displays the first record of the table. It confused me, because i did this as soon as I had setup the database with no visual basic code assisting, so there wasn't even a connection string?!
One functionality i want to have is to press a button and cycle through the table's records using the form by the unique id, how would I do this? I'm essentially asking how can I enter a number in a textbox which would then return me the relevant primary key and data attached to that record.

I've downloaded the ODBC driver and the MySQL driver and installed them on my system (Win XP SP3). However, the only data sources that are showing up when I try to add a data connection are Access & 2 SQL Server objects. Is there something else that needs to be setup in order for Visual Studio to allow additional data sources? I'm currently running VS 2010 Express.

I got the whole database thing figured out now I've got a problem with these parametrized queries. If I remove them and just explicitly put in the data I'm looking for the datareader works, however doing as I have below returns no results in the datareader.

I have a small vb.net application that fires a crystal report through crystal viewer.
The report uses an ODBC connection provided by 32-bit software accounts package, which is installed in the ODBC 32-bit This all works fine on 32-bit XP and 32-bit Win7 with no problems, When run on a win7 64-bit machine the application launches ok, but when it comes to running the report, it prompts for a database logon box for the odbc connection.
When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,

I have determined thanks to the last q & a that there is something wrong with my "save to db" code as well as my "retrieve to picture" code. Even If I manually save the pic in the db it stil wont retreive. This is code i patched together from 3 or 4 examples around the net.

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.

What 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
Imports MySql.Data.MySqlClient
Public Class Form1
Function UpdateRecord(ByVal query As String) As Integer
[CODE]...
How i can allow the _ into the application, because the only databases that don't have a _ in the user or dbname are a) Paid ones which i DO NOT have the money for or self hosted ones, i cannot leave my computer on 24/7

I have a query from within my vb.net code which searchs for a record by date. The date being entered via the code is in format dd/mm/yyyy, i need to search in the database using yyyy/mm/dd? Ideally i thought there may just be a function within MySQL which will convert this. If not in vb.net to convert the string 01/01/2011 to 2011/01/01?

I have a Access 2003 backend db and I'm using vb 2005 to connect to the db via conntection string. It works ok! I can see all the tables but only some of the queries. Why should some queries be absent? In 1 query I have a user define function which cuts up a string. I've created a new VB project with a new connection but the same result. I've compacted the database with not change.

I am getting the following ODBC exception when I moved my development platform from Windows XP X86 to Windows 7 X64: ERROR [IM014] [Microsoft][ODBC Driver Manager] The specified DSN contains an architecture mismatch between the Driver and Application What I'm sure it means is that the server it is connecting to is 32 bit, and the computer I'm running on is 64 bit and the ODBC driver in use is 64 bit.
The application I am writing is set to run in 32 bit mode because some of the third-party software that we employ is not 64 bit compatible. I tried downloading a 32 bit driver and changing the DSN but it did not fix my issue. I still get the exception. If anyone has any links for 32 bit SQL drivers, or how I could fix this by changing the project around, I'm all ears.
