    Rowerror

    If I use a DataTable
    DataGrid1.DataSource = DataSet1.Tables(0)
    it displays all rows and column from the table.

    If I use a DataRowArray
    DataGrid1.DataSource = DataSet1.Tables(0).Select()
    it displays only 2 colums RowError and HasErrors
    the rowcount is the rowcount from the table but RowError is in all rows
    blank and HasErrors is in all rows "False"

    Why does it not display the same output?


    Thanks

    So, maybe I'm completely wrong and "Tables" is a method (never worked with either of those classes), but if Tables is a collection than that is VB code, and VB is 1 indexed, not 0.

    Vb is not 1 indexed. At least not as a rule. It can be however.

    As to the problem in the OP doesn't Select() require a parameter of some sort?

    Geez, you're right:

    The range of the array index can be 0 to 10 or 1 to 10, depending on the default value indicated with the Option Base statement.
    What a stupid language...

    Vb coders may say the same about C#

    Maybe, but they would be wrong. It's not really a subjective thing, VB is just a poorly designed language from top to bottom, but I'll stop ranting now :P

    I agree VB on the surface seems pretty darn stupid.

    I have learned that it is far easier to program VB on a non-US keyboard where the { and the ; are not inheritantly on the keyboard. I got so tired of typing Alt + plus whatever the stupid character code was that after two weeks I was ready to convert. Thank god I got to come home.
