Re: call (from script) which Tray is the Paper Source to be used when printing a report.

Sorry about that... I just notice it also....

Create the cs file and copy this into it:

using System;

using System.Collections.Generic;

using System.Text;

using System.Runtime.InteropServices;

namespace Unmanaged_RAS10_CSharp_Printers

{

    class PaperSizeGetter

    {

        public static string OutputPort = String.Empty;

        public static string paperName = String.Empty;

        [DllImport("winspool.drv", CharSet = CharSet.Auto, SetLastError = true)]

        public static extern int DeviceCapabilities(string pDevice, string pPort, short fwCapabilities, IntPtr pOutput, IntPtr pDevMode);

        public static int[] Get_PaperSizes(string printer, string paperName)

        {

            string text1 = printer;

            //string paperName;

            int num1 = FastDeviceCapabilities(0x10, IntPtr.Zero, -1, text1);

            if (num1 == -1)

            {

                return new int[0];

            }

            int num2 = Marshal.SystemDefaultCharSize * 0x40;

            IntPtr ptr1 = Marshal.AllocCoTaskMem(num2 * num1);

            FastDeviceCapabilities(0x10, ptr1, -1, text1);

            IntPtr ptr2 = Marshal.AllocCoTaskMem(2 * num1);

            FastDeviceCapabilities(2, ptr2, -1, text1);

            IntPtr ptr3 = Marshal.AllocCoTaskMem(8 * num1);

            FastDeviceCapabilities(3, ptr3, -1, text1);

            int[] sizeArray1 = new int[num1];

            for (int num3 = 0; num3 < num1; num3++)

            {

                string text2 = Marshal.PtrToStringAuto((IntPtr)(((long)ptr1) + (num2 * num3)), 0x40);

                int num4 = text2.IndexOf('\0');

                if (num4 > -1)

                {

                    text2 = text2.Substring(0, num4);

                    paperName = text2;

                }

                short num5 = Marshal.ReadInt16((IntPtr)(((long)ptr2) + (num3 * 2)));

                int num6 = Marshal.ReadInt32((IntPtr)(((long)ptr3) + (num3 * 8)));

                int num7 = Marshal.ReadInt32((IntPtr)((((long)ptr3) + (num3 * 8)) + 4));

                sizeArray1[num3] = System.Convert.ToInt32(num5);

            }

            Marshal.FreeCoTaskMem(ptr1);

            Marshal.FreeCoTaskMem(ptr2);

            Marshal.FreeCoTaskMem(ptr3);

            return sizeArray1;

        }

        public static int FastDeviceCapabilities(short capability, IntPtr pointerToBuffer, int defaultValue, string printerName)

        {

            int num1 = DeviceCapabilities(printerName, OutputPort, capability, pointerToBuffer, IntPtr.Zero);

            if (num1 == -1)

            {

                return defaultValue;

            }

            return num1;

        }

    }

}

I'll check the other file.
