Load Data From Database Table Fields Into Textboxes In A Windows Application?
Apr 26, 2009
I have created an windows application which stores it data in a database. What I would like to know is how do I access the tables in the dataqbase and transfer the data in them into textboxes on the forms in my application. I can connect to the database and view the tables, but I have'nt got any idea how to get the data from the fields in the tables into the appropriate textboes on the application forms.

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?

I'm looking for a way to combine a field from multiple tables into a single field in a new table. Because the data populating the tables is coming from an outside source, I would prefer not to change the data in the original files. I have a separate table for each year because this is the way the data is provided. The field layout is not consistent from year to year, but each year there is a field that we'll call "score." I'd like to pull the field "score" from each year's table and have it populate a "score" column in a new table along with the year of the data so that all the years' scores are in the same place. Is there a way to do this using Visual Basic + Access?

I am trying to create a form which will be fed by an underlying database to create multiple form fields for each entry in an underlying database table. This is for a program to monitor patients under anesthesia, and prior to surgery, the doctor will choose which monitors they will be using. Then, on the actual monitor screen which will pop up every X minutes, there will be a text box and a check box for each chosen monitor. I am relatively new to VB, so I have tried to illustrate what I am needing but using the logic that I know from my previous life in PHP.
I am using DevExpress's layout control to place the form fields, so that is the code in the middle of the first loop (on_load), and I know that part works, I just need to know how to name the fields and then recover those fields and commit the values to the database. (the text boxes are added to the database, the check boxes are used to determine if an entry is made for that monitor- i.e. at the end of surgery if a monitor is turned off). I know that my syntax for naming the fields is no where close to correct, and it probably would not work in PHP, but I remember doing something like this in a PHP application I built long ago. [Code]

you would think that this would be simple, but with some sample code i found i could only get it to load and not save, or it would be written for a datagrid and not a datagridview.

I'm attempting to create and populate a table in a new Microsoft Access (Jet) database using VB.Net 2008 Express under Windows XP Pro SP3. The database and table are being created properly, but loading the table proceeds VERY slowly. When I am loading the table, no complicating factors that might impact performance, such as indexes or table relationships have been defined. The table to be loaded is made up of relatively short rows consisting of three single byte columns, and one (four byte) integer column. I am loading approximately 16 million rows, and this is literally taking hours, while the same data can be interactively imported into Microsoft Access from a .csv file in minutes. I am trying to batch load the rows, 64K rows at a time, in order to avoid the overhead of individually transacting/committing each row individually, but suspect that I must not be doing something right. Key code that I am using for this process is provided below.

Im currently doing a small programme of a register system. I need to add a new group box filed with a few textboxes and a couple comboboxes for each entry in a access 2010 database. for example if i had someone called bob in my database with his details i would like the GUI of the VB app to add in a new textbox for the name, a textbox for the address ect in a set order, this needs to work for multiple entry's so the textboxes ect don't overlap but be placed neatly below the added textbox.

Alright it's been awhile since I messed with this project, so here goes. It's an appointment scheduler and everything works except two things: I can't edit existing appointments and it only records the current time, not the timeslot I click on.
If I try to edit an existing appointment it doesn't get the row data, just shows me blank text boxes. I assume I have to have those text boxes read the info from the database, but I don't know how to do that.
This is how it looks:
So, you double click a time slot and it looks like the second window. You can right click on an existing appointment to edit it, but when you do that all the text boxes remain blank like you're inserting a new one.
What code would I use to read whatever row's data I am trying to edit and insert it back into the boxes?
Here is the code I use to add new rows to the DB:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
Dim NR As TestAppointmentDataBaseDataSet.AppointmentRow
