For i = 0 To ds.Tables(0).Rows.Count - 1

What does this code mean and the other one? Can you explain what is the difference between this two code.

VB

For i = 0 To dt.Tables(0).Rows.Count - 1
            MsgBox(dt.Tables(0).Rows(i).Item(0))
        Next

Solution 1

Both Code Block works same. The code will display a messagebox showing count(1,2,3,4....) upto rows count of a dataset(ds) or datatable(dt)

The difference is only of the dataset and datatable.

Thanks

Solution 3

Both the codes are same and it looks like ds and dt both means the same i.e, dataset.
This code will give you value of first column in each row of your datatable in msgbox

Solution 2

The only difference is ds and dt but its the same a dataset. You are displaying data from a dataset.
