Error updating new column...!

[explode]

My table has 5 columns: Broj iksice, Prezime, Ime, Broj indeksa, Broj
pohadjanja.
This is the code in the dataset designer VB made it by it self:

Private Sub InitClass()
Me.columnBroj_iksice = New System.Data.DataColumn("Broj iksice",
GetType(Double), Nothing, System.Data.MappingType.Element)
Me.columnBroj_iksice.ExtendedProperties.Add("Gener ator_ColumnPropNameInRow",
"Broj_iksice")
Me.columnBroj_iksice.ExtendedProperties.Add("Gener ator_ColumnPropNameInTable",
"Broj_iksiceColumn")
Me.columnBroj_iksice.ExtendedProperties.Add("Gener ator_ColumnVarNameInTable",
"columnBroj_iksice")
Me.columnBroj_iksice.ExtendedProperties.Add("Gener ator_UserColumnName",
"Broj iksice")
MyBase.Columns.Add(Me.columnBroj_iksice)
Me.columnPrezime = New System.Data.DataColumn("Prezime",
GetType(String), Nothing, System.Data.MappingType.Element)
MyBase.Columns.Add(Me.columnPrezime)
Me.columnIme = New System.Data.DataColumn("Ime",
GetType(String), Nothing, System.Data.MappingType.Element)
MyBase.Columns.Add(Me.columnIme)
Me.columnBroj_indeksa = New System.Data.DataColumn("Broj
indeksa", GetType(String), Nothing, System.Data.MappingType.Element)
Me.columnBroj_indeksa.ExtendedProperties.Add("Gene rator_ColumnPropNameInRow",
"Broj_indeksa")
Me.columnBroj_indeksa.ExtendedProperties.Add("Gene rator_ColumnPropNameInTable",
"Broj_indeksaColumn")
Me.columnBroj_indeksa.ExtendedProperties.Add("Gene rator_ColumnVarNameInTable",
"columnBroj_indeksa")
Me.columnBroj_indeksa.ExtendedProperties.Add("Gene rator_UserColumnName",
"Broj indeksa")
MyBase.Columns.Add(Me.columnBroj_indeksa)
Me.columnBroj_pohadjanja = New System.Data.DataColumn("Broj
pohadjanja", GetType(Integer), Nothing, System.Data.MappingType.Element)
Me.columnBroj_pohadjanja.ExtendedProperties.Add("G enerator_ColumnPropNameInRow",
"Broj_pohadjanja")
Me.columnBroj_pohadjanja.ExtendedProperties.Add("G enerator_ColumnPropNameInTable",
"Broj_pohadjanjaColumn")
Me.columnBroj_pohadjanja.ExtendedProperties.Add("G enerator_ColumnVarNameInTable",
"columnBroj_pohadjanja")
Me.columnBroj_pohadjanja.ExtendedProperties.Add("G enerator_UserColumnName",
"Broj pohadjanja")
MyBase.Columns.Add(Me.columnBroj_pohadjanja)
Me.Constraints.Add(New
System.Data.UniqueConstraint("Constraint1", New System.Data.DataColumn()
{Me.columnBroj_iksice}, true))
Me.columnBroj_iksice.AllowDBNull = false
Me.columnBroj_iksice.Unique = true
Me.columnPrezime.MaxLength = 255
Me.columnIme.MaxLength = 255
Me.columnBroj_indeksa.MaxLength = 255
End Sub

I get an error when I add new column with this code:

Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button4.Click
Dim noviStupac As Data.DataColumn = New Data.DataColumn("Test
Marko", System.Type.GetType("System.Int32"), Nothing,
System.Data.MappingType.Element)
noviStupac.AutoIncrement = False
noviStupac.DefaultValue = 0

Try
Form2.Studenti1Data.Tables.Item(Index(ComboBox1.Te xt)).Columns.Add(noviStupac)
'Dodaje stupac u tablicu

Form2.Studenti1Data.Tables.Item(Index(ComboBox1.Te xt)).AcceptChanges()

"Fill") 'Ponovo prikazuje tablicu u datom prozoru

Catch ex As Exception

MsgBox("Vec postoji dati stupac!", MsgBoxStyle.Exclamation,
"Upozorenje!")

End Try
End Sub

The error is:

Explode,

It is hard to see, but does your table have a primary key, and is it set?
