When you are working with a database, is it then possible to make the program save stuff, so when you close and open the program, it could etc. save a text in a textbox?

I have a form that contains a Textbox + Three sets of radiobuttons.
my project idea is to store in any database the values selected or entered by the user.
Textbox goes Name.
First set of radiobuttons are the job position - manager - superviser etc....
Second set "" "" the Period (Shift)- day - nite
Third set "" "" The Condition - part-time - full-time
Anyway, my problem is how to insert those values into a database, something very simple such as MSAccess (is possible?)
Okay, I've made a local database now and everything is okay. But I don't want the normal data grid view, I want to display the information in a list view. How can I do that? Do I have to make some sql queries or something?
View 8 RepliesI have made a small form where I have bound textbox with records from database.Although my code for inserting and updating the record seems fine and working. But when I view the database, tables i see no inserts/updates made there. But When I run my application again, I see the records in the bound textbox but only for some seconds (for around 1 and half minutes), although they are not shown in the database (tables) actually.
When I close the application and run again it after 1-2 minutes there are no more records bound to the textbox, since no records at all.How can this be possible. I don't have any idea what's going on.

View 2 RepliesI need to import data from Excel into a MySQL 5 database. The format of the column in excel is set to "Time". the field value looks something like this:
17:20:00 If I do this in my vb.net
strTimeIn1 = Trim(jobdt.Rows(j).Item(7).ToString)
I get this in my Immediate window when debugging:
"12/30/1899 4:10:00 PM"
what's the correct way to convert that string to a time value so I can insert into a datetime field in my database with no issues.
I'm quite new into the programming game, I've been working on this program for a few weeks now, and its coming along, but the method I searched for entering new rows of data into my table doesn't seem to update my tables after I try entering data.

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)

The INPUT line needs to be fixed. From what I can see, I need to move it all to a single field and use a split to parse it, correct? As I look at the entries on this site, all the code seems to use stream readers. Why would the book not do that? Am I missing something?

I am creating a feature in my application that will allow a logged in user to add additional users to be logged in. The usernames and passwords are kept in a single database created in Access 2007.

I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.
