Hi,

I am not able to get the output from a function in Fortran DLL called from Vb.net.Here goes the mapped declaration of function of Fortran in Vb.net

<dllimport("fortran.dll",> _
Public Shared Sub FunctionName(ByRef Cosnt1 As Integer, ByRef Cosnt2 As Integer, ByRef Param1 As Integer,ByRef InputArray(1,1) As Double, ByRef TempArray(1,1) As Double, ByRef OutArray(1,1) As Double, ByRef FlagArray(1,1) As Integer, callbakc1 As CallBack11)
End Sub

Where InputArray ------------ 2 Dimensional array which contains input values
OutArray ------------- 2 Dimensional array which should contain output values after the above function call
I am able to execute the above function but 'OutArray' is not returning any values.

thanks meel.It doesn't work in our scenario b'cause of multi-dimensional array and callback function.Pls let me know if you have any alternate solution.
