Another option would be to store the time as a number, and when you retrieve it from your database, you can format it in your own way. For example, I store time fields as 6 digit numbers. The first two digits for the hour (military time) the second two digits as minutes, and the last two digits as seconds. So when I store them to my data base I only have to take the datetime object and do this:

myDataBaseRow("myTimeColumn") = objDateTime.ToString("HHmmss")

I know this isn't what you asked for, but I thought another view point might be helpful.

Here is the bit that will get the highest sno for each user
SELECT MAX(sno) AS sno, name FROM MyTable GROUP BY name

Add that as a subquery and join on to it like another table. Like this:

SELECT s.sno, s.name, m.desc
FROM MyTable AS m
INNER JOIN (SELECT MAX(sno) AS sno, name FROM MyTable GROUP BY name) AS s
ON s.sno = m.sno AND s.name = m.name

for this you have to use corolated queries following the example

SELECT sno, name, desc FROM WHERE sno=(SELECT MAX(sno) FROM

I think ur problem has solved

That will return the row "8 suma jsakdksladksadks" only.

No, that will result in:

8 suma

only. Which does not match the output the OP requested.

displaying a data in textbox

Rharzkie15-Jul-07 22:57

15-Jul-07 22:57

Its me again, i making a grade data entry. I have a database of diffenrent subjects. The fields that i will going to use is these: Subject code, Subject description, and professor.

What I want is to view the subject description and the professor in the textboxes when I select a subject code in the combo box.

I had already made an OleDbDataAdapter for that, and the subject codes was the data member in the combobox. The subject codes is already the item of the combobox but my problem is, the subject description and professor was not appeared in the textbox. What I want is this to view to its corresponding textboxes.

I used this code:

For ctr = 0 To DataSet31.studentsubjects.Rows.Count - 1<br />
            dr = DataSet31.studentsubjects.Rows(ctr)<br />
            If ComboBox1.SelectedItem = dr("subject") Then<br />
                subjdesc.Text = dr("subjdesc")<br />
                prof.Text = dr("professor")<br />
            End If<br />
        Next

Is the code above correct??? If its not, what is the right code????

Where will I going to put the codes???

Can you please name your variables with good names rather than accept the defaults that Visual Studio gives you.

Rharzkie wrote:
ComboBox1.SelectedItem = dr("subject")

What does ComboBox1.SelectedItem return? Put a break point down and see what value it is returning. Also it will aid the debugging process if you assign the result of method and property calls to something then test on the local variables - it will make it easier to see what is going on in the debugger.

The ComboBox1 is for the list of the subject code. I use the DISTINCT in query builder to display the items in the combobox. I use the OleDbDataAdapter1 for that.

But the connection that i will going to display in textbox is OleDbDataAdapter3. In short, i use different connection from the combobox and the textboxes. Is this correct?

Yes, but ComboBox1 still isn't a good name for it, is it?

How do you keep track of what each of these does?

Rharzkie wrote:

I have no idea. This code is obviously a mess. My suggestion is to start by naming things properly. Then it might be an idea to create a DAL and remove all your database interaction out of the user interface classes. It might also be an idea to do what I asked in my previous post and answer the question I asked. ("What does ComboBox1.SelectedItem return?" - And I want actual values and object types, not what you think it should return)

Date format in cell

I currently have an app up and running in .NET. We have just built the server for the app to run on but there seems to be a problem with some of the returned date formats within the app itself. I checked the original test db and the date format was english style 31/12/2007 but on the new database it was amercian style 12/31/2007. Is there a setting in SQL server 2005 that would aler this?

Dates are not stored any any locale dependent format. When you get data out the database you should get a DateTime object which you can then format as you need with ToString()

e.g. myDate.ToString("dd/MM/yyyy")
