I'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.
View 3 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 4 RepliesI developed an application in VB.Net 2010 Express by which my users can updated the data in their offices and send XML files (total 4 xml files) for that particular date - its working fine I am getting 100's of files on daily basis to my FTP servers in a common folder.
Now i want to make an application that read those XML file at a scheduled intervals and import that to MySQL database tables. Also it should keep a log of files that has been imported in order to avoid duplicate importing of files.
I'm trying to build an application so that the user can see table entries in a mysql database. I'm programming this in visual basic. How can this be done?
View 1 RepliesI am trying to make a very simple program that connects to a MySQL database using VB.NET. My program only has one form and one label. I setup my MySQL database to have a table and one field (a VARCHAR)called "Tab1". I manually inserted the value "CLOSED" into the Tab1 field using PHPMyAdmin. I want my program to change the value of the field to OPEN/CLOSED and I also want the label text on my form to change too when it's clicked.

My project is about recipes. I want to automatically create table inside in mysql database when I hit the add button on my project through codes. First is when I input recipe name in the textbox1 then my input will be saved in the recipes table under recipe name column and also create a new table through codes on what i input in the textbox1
Example of my database in sql
texbox1 input will be save here
recipes - id, recipename
And then it will also automatically create a new table in mysql database, create newtable, with id, quantity ,unit, ingredients
Private Sub iadd()
Dim command As New MySqlCommand("insert into recipes (recipename) values ('" & TextBox1.Text & "')", connection)
Try
connection.Close()
connection.Open()
command.ExecuteNonQuery()

I'm trying to populate an Access Data Table (5 columns) with a Visual Studio front end, but I'm not clear on how to pass the data through the parameters. I have created a connection, a data adapter, and a data set in the project by dragging them onto the form. I know the connection works because I can see my Access database using the Server Explorer. I have an INSERT command in the data adapter and the parameters are represented in this command with question marks. See my insert command below INSERT INTO tbl_ConstraintLogs (ConstrinatChangeReason, ConstraintTagName, ConstraintValueBefore, ConstraintValueAfter, onstraintTimeChange) VALUES The values that I want to pass to the database are coming from text boxes or they are program generated. For example: If I have a variable in my program called "AbcValue", how do I get the value of this variable into the database as the first parameter. I was trying to use the "Fill" command, but I'm at a loss here.

View 1 RepliesI am using VS2008 and SQLite. I have created a database and several tables and am attempting to populate the tables with data from arrays.
The following code (example) works fine but stops after it inserts 30 to 50 records. I am running the VB code in debug mode and when it stops, I press pause to see where it is. It stops on "SQLcommand.ExecuteNonQuery()" and when I press continue (F5) it will insert another 30 to 50 records.
I do not get an error message. Is this a timeout issue? How do I keep the loop running to the end of the array?
Following is example code.

how to input data in mysql, different tables with one query?is it possible to do in gridview in vb.net 2008?
View 4 RepliesI've been working with a remote mysql database. The design of the database pretty much requires that I use SELECT commands that include multiple tables, and sometimes joins. Updating a single table query is SO EASY, yet dealing with multiple tables has me pulling my hair out.

What's killing me is that if I make a change to a field in the products table in the datagridview and press button1, the changes are saved. If I make a change to a field in the specials table in the datagridview and press button2, the changes are saved. If I combine the two updates together in a single routine, only the first one is saved. I presume this is because after the first update executes, the dataadapter no longer reports that there are any changes to save, since the update already happened.
I've tried breaking this up into separate dataadapters for each table, but then even using dataset relations, I can't get the data together in a single datagridview. On top of that, the grid itself is only intended to be used for searching and querying data. It still needs to be bound along with a set of textboxes that accept the input.
Lastly, this database is part of an ever-evolving website database with dozens of tables that need interfacing. I just can't see manually maintaining hand written sql statements for every table. That's why I've been working so hard to get the commandbuilder to handle it.
I have a combobox in my form which I want to fill with data from one column in an SQL database. Any idea on how I do this?

I have a project in Visual Studio 2008 and there is a working data connection to a MySQL database. In other words, I can query the db directly from Visual Studio and it will display the results.
I've tried a couple of approaches that I found online for writing a connection string and accessing the db, but no luck yet.
All I'm trying to do is code a button to query the db and then reset the text property of a label/textbox to display the results based upon another label/textbox value.
The pseudo-code I am imagining is something like this:
Private Sub query_submit_button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles query_submit_button.Click
result_textbox.Text = SELECT field FROM table WHERE otherfield = key_textbox.Text
End Sub
I didn't see any related questions posted on SO - forgive me if I missed one that already exists and this is a dupe.
What is the correct way to accomplish this?

Using MySQL 5.1
I have been reading about ADO, SQL, datasets, data adapters etc and have gone into information overload. My next step is to create a simple data file of my own that I can manipulate, update, sort etc in VB Express. Do I need another piece of software? I read about MySQL, which I understand is primarily used to access databases on the net, but can that be used to create a simple local data file on my PC? Can you simply hard code something in VB Express?

I am an absolute newbie in both oracle and visual basic. I have covered some basics as tutorials and want to develop a database using Visual basic as front end and Oracle as back end. I have Visual Studio 2008 installed and I will use Visual Basic from that. I also have Oracle 10g express edition installed on my system.
View 6 RepliesWe are thinking about changing our current database system, MS Access 2007 front end and MS SQL Server 2005 backend to using a higher level language such as Visual Basic .Net. I wonder if this is the BEST solution for data management? Currently, among others, we have two big database programs that handle more than two hundred users and it's crashed often. That's the reason we think about changing to something that can handle these database programs effectively preferably using MS technology such as .Net.
