thanks for ur response..
here is the code

Dim appExcel As Excel.Application
Dim appBook As Excel.Workbook
Dim appSheet As Excel.Worksheet

Private Sub cmdExcel_Click()
Set appExcel = New Excel.Application
appExcel.Visible = True
Set appBook = appExcel.Workbooks.Add()
ActiveCell.FormulaR1C1 = "a"
Range("A2").Select
ActiveCell.FormulaR1C1 = "b"
Range("A3").Select
ActiveCell.FormulaR1C1 = "c"
Range("A4").Select
ActiveCell.FormulaR1C1 = "u(a,b,c)"
Range("A5").Select
ActiveCell.FormulaR1C1 = "v(a,b,c)"
Range("A6").Select
ActiveCell.FormulaR1C1 = "w(a,b,c)"
Range("B1").Select
ActiveCell.FormulaR1C1 = "1"
Range("B2").Select
ActiveCell.FormulaR1C1 = "1"
Range("B3").Select
ActiveCell.FormulaR1C1 = "1"
Range("B4").Select
ActiveCell.FormulaR1C1 = _
"=18*R[-3]C+14*R[-2]C+16*R[-1]C-(R[-3]C^2+R[-2]C^2+R[-1]C^2)-120"
Range("B5").Select
ActiveCell.FormulaR1C1 = _
"=12*R[-4]C+10*R[-3]C+8*R[-2]C-(R[-4]C^2+R[-3]C^2+R[-2]C^2)-56"
Range("B6").Select
ActiveCell.FormulaR1C1 = _
"=14*R[-5]C+8*R[-4]C+12*R[-3]C-(R[-5]C^2+R[-4]C^2+R[-3]C^2)-74"
Range("A8").Select
ActiveCell.FormulaR1C1 = "sum of squares"
Range("C8").Select
ActiveCell.FormulaR1C1 = "=R[-4]C[-1]^2+R[-3]C[-1]^2+R[-2]C[-1]^2"
SolverOK SetCell:="$C$8", MaxMinVal:=3, ValueOf:="0", ByChange:="$B$1:$B$3"
SolverSolve
End Sub

the solverok and solversolve is creating a problem. it works fine with excel vba but not with vb6. it says function or sub not defined.

kindly help.
thanks.
