c# and Preferences

Christian Krätschmer

Hello i'm new to BricsCAD developement and wanted to start with some basic stuff.

So i tried to programmatically change some values like the template path but i can't get the preferences object from the Brics-application.

How can I get this done in C#?

Hi, Most of these settings are available through Application.GetSystemVariable,  example.

[code] [CommandMethod("doit")] static public void doit() { AcAp.Document doc = AcAp.Application.DocumentManager.MdiActiveDocument; try { string env = AcAp.Application.GetSystemVariable("TemplatePath") as string; doc.Editor.WriteMessage(env); AcAp.Application.SetSystemVariable("TemplatePath", your path); } catch (System.Exception ex) { AcAp.Application.ShowAlertDialog( string.Format("\nError: {0}\nStackTrace: {1}", ex.Message, ex.StackTrace)); } }[/code]

Cheers : )

sorry for the formatting : |

Also, these might be handy as they wrap acedGetEnv and acedSetEnv

        [System.Security.SuppressUnmanagedCodeSecurity]
        [DllImport("Brx13.DLL", CharSet = CharSet.Auto,
            CallingConvention = CallingConvention.Cdecl)]
        internal static extern int acedGetEnv(string envName, StringBuilder ReturnValue);

        [System.Security.SuppressUnmanagedCodeSecurity]
        [DllImport("Brx13.DLL", CharSet = CharSet.Auto,
            CallingConvention = CallingConvention.Cdecl)]
        internal static extern int acedSetEnv(string envName, StringBuilder NewValue);

        public static string GetEnv(string envName)
        {
            StringBuilder buf = new StringBuilder(2048);
            acedGetEnv(envName, buf);
            return buf.ToString();
        }

        public static bool SetEnv(string envName, string newValue)
        {
            StringBuilder buf = new StringBuilder(newValue);
            return acedSetEnv(envName, buf) == 5100;
        }
