I have program written in VB.Net.
the program is form based
I'm calling myvbnet.exe from the other program, let's say another c++ program.

I have following code in myvbnet.exe
Code: 
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim arg1 As String =  ReadCommandLine()
End Sub

Function ReadCommandLine() 
 Dim arg1 As String
arg1 = Environment.CommandLine
ReadCommandLine = arg1
End Function

I used ShellExecuteEx to call myvbnet.exe and pass the argument

but I got the following very long error message
Code: 
the application attempted to perform an operation not allowed by the security policy. The operation required the SecurityException . To grant this application the required permission please contact your system administrator, or use the Midrosoft.NET security policy administration tool. 

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

I got the same message even after taking the line
arg1=Enviroment.CommandLine

How can I call VB.Net Program with arguments from my C++ program?
