VS 2008 Update Access Data Row?
Jan 26, 2010
I am writing a signout program in vs2008 using an access database.I have created forms and can call student and equipment info from the tables.I got the sign out part working and can add data rows to my table containing that information now I seem to be stuck in a stupid place. Signing the equipment back in I call the record to fill a form now all I want to do is add the date to the RETURNDATE column and save the record back to the DB and I am stuck at that point and cant seem to find the answer on the web.

I have a simple vb.net app and I'm trying to update a one row Access table with data from some textboxes. This is a learning exercise for me as I am coming back from not programming for almost 10 years, and know there are lots of other ways to manage this data, but I'm just trying to understand different aspects of ADO.net a little better.
The ERROR I'm trapping is:
"Syntax error in UPDATE Statement"
Any thought's as to what is going on? (See CODE and stuff below)
Here's the Scheme printed from ACCESS showing the exact spelling of the database table and column names:
Table: MaxTime Name Type Size
ID Long Integer 4

I'm an experienced Office & VBA programmer, I am new to .NET programming. I'm in the process of migrating an Access 2007 database application from Access to Visual Studio Visual Basic project for further development. In particular, I am interested in using .NET controls to display data in a user-friendly hierarchical grid control.The data for each hierarchical display is stored in two separate tables (I call them tblData and tblExtraInfo), and then I use a query to join the data and prepare for display (I call the query qryBOM).

Which method is professional to insert, update, delete data using either MS Access database or SQL database?
1) Using wizard to connect the database
2) Writing code manually such as
"INSERT INTO CUSTOMERS(CNO, CNM, CTY, TEL, TDT, NTS, UID) VALUES(@CNO, @CNM, @CTY, @TEL, @TDT, @NTS, @UID)")
I need to insert data from one form (Collection_Form) to 2 database tables. Like, Collection form data to be added in the following 2 tables:
1) Customer_Account
2) Collection_Account

i have to update the values in my database some of them are integer, some string and some date (as you can infer from the formatting)
i am using the following query:
UPDATE PatientProfile SET HospitalRegNo=" + hregno + ", PatientName='" + pname + "', PatientAge=" + page + ", PatientSex='" + psex + "', Address='" + add + "', ContactNo='" + cno + "', AdmitDate=#" + adat + "#, OperDate=#" + odat + "#, DischargeDate=#" + ddat + "# WHERE PatientNo=" + pno + ""
but its not working... i think there's a problem in formatting the date type variables

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)
If IsDBNull(txtRow(7)) = False Then

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I'm looking into adding some unit tests for some classes in my data access layer and I'm looking at an update routine that has no return value.It simply updates a row based on the id you provide at whichever column name you provide.Inside of this method, we collect the parameters and pass them to a helper routine which calls the stored procedure to update the table.Is there a recommended approach for how to do unit testing in such a scenario?

I cannot figure out how to change the data in a listbox. I'm being driven completely mad by vb.net, finding it very very complicated.
Ok I have two list boxes on a form that contain correlated data i.e. the first item in the first list box corresponds to the first item in the second list box.
Under the two list boxes I have two text boxes for data entry.
For Example :
LstTagDatabaseLoop LstTagDatabaseSource
TxtTagDatabaseLoop TxtTagDatabaseSource
I want to Add Update and Remove items from the list. If the user selects an item, I want the selected item in the other list to change to correspond. I also want the two text boxes to be udpated with the currently selected item.
[Code].....
however this invoked the selectedindexChanged sub umpteen dozen times and while in the end it did actually update the data, its obviously not the right way.
I found ListViews which perhaps is more appropriate but I couldn't get my head around it at all so returned to trying to use these listboxes. Is there a different object I should be using.
I'm finding vb.net to be too complicated for a hack programmer like myself...

Here is the code snippet
objCommand.CommandText = "UPDATE tblCustomers SET weight= @weight, height= @height WHERE id=@id "
What i want to do is the following:
I have a form and i want,by clicking the appropriate button, to update the height and weight values which have the specified primary key 'id'.
The primary key 'id' is of type IDENTITY.The problem is that the above code does not work. It says Must declare the scalar variable "@id".

I have programmed gridview, where you Edit a row and then update it using link buttons provided on the row.But when a user has to make couple of edits on the same grid, it should be saved with one button click and one refresh to reflect updated data.
