VB API allows user to start Creo in both non-interactive and non-graphical mode.

VB API only supports Creo in asynchronous mode, and while starting Creo, use the following option to initiate it in non-interactive mode

• -g:no_graphics—Turn off the graphics display.
• -i:rpc_input—Causes Creo Parametric to expect input from your asynchronous application only.

Note:

• Both of the arguments are required
• Order of the argument is not important

Code Sample

' Import Statements
Imports pfcls
Imports System.Configuration

' Call Function
private void start_non_interactive_mode(object sender, RoutedEventArgs e)
{
    IpfcAsyncConnection AConnection;
    CCpfcAsyncConnection CConnection;
    Dim Command As String = ConfigurationManager.AppSettings("pro -g:no_graphics -i:rpc_input").ToString()
    Dim TextPath As String = ConfigurationManager.AppSettings("C:\application_text_path").ToString()

    CConnection = new CCpfcAsyncConnection() ;
    AConnection = CConnection.Start (Command,TextPath);

    if (AConnection.IsRunning() = true  )
    { 
        ' Your Code 
    }

}
