Topic: AutoCAD 2013: encoding of Document.Editor output

[Andrey Bushman]

Windows 7 x64, AutoCAD 2013 SP1.1.
This problem are exists in AutoCAD 2013 only (look the screen below). In the AutoCAD 2009-2012 it works fine.

Code - C#: [Select]

1.             String _args = sb.ToString();
2.             String exeName = new FileInfo(Path.Combine(curDir, @"..\..\recovery")).FullName;
3.             Process proc = new Process();
4.             ProcessStartInfo info = new ProcessStartInfo();
5.             info.CreateNoWindow = true;
6.             info.RedirectStandardOutput = true;
7.             info.UseShellExecute = false;
8.             Int32 codepage = CultureInfo.CurrentCulture.TextInfo.OEMCodePage;
9.             info.StandardOutputEncoding = Encoding.GetEncoding(codepage);
10.             info.FileName = exeName;
11.             info.Arguments = String.Format("{0} -clear", _args);
12.             info.WorkingDirectory = new DirectoryInfo(Path.Combine(curDir, @"..\..\")).FullName;
13.             proc.StartInfo = info;
14.  
15.             proc.Start();
16.  
17.             String outputText = String.Empty;
18.  
19. #if acad2013
20.             Encoding enc = Encoding.Unicode; // What encoding I must point here?
21.             Int32 b;
22.             List<Byte> bytes = new List<Byte>();
23.             while ((b = proc.StandardOutput.BaseStream.ReadByte()) != -1)
24.                 bytes.Add((Byte) b);
25.             Byte[] bytes2 = Encoding.Convert(Encoding.GetEncoding(codepage), enc, bytes.ToArray());
26.             outputText = enc.GetString(bytes2);
27. #else
28.             outputText = proc.StandardOutput.ReadToEnd();
29. #endif
30.  
31.             if (doc != null) {
32.                 if (printMsg) {
33.                     doc.Editor.WriteMessage(outputText);
34.                     doc.Editor.WriteMessage(Environment.NewLine);
35.                     doc.Editor.WriteMessage("&#1054;&#1087;&#1077;&#1088;&#1072;&#1094;&#1080;&#1103; &#1079;&#1072;&#1074;&#1077;&#1088;&#1096;&#1077;&#1085;&#1072;."); // Operation is complete (ru-RU)
36.                     doc.Editor.WriteMessage(Environment.NewLine);
37.                 }
38.             }
39.  

In the AutoCAD 2013 the result looks so (look attached screen below)...

I have tried to look all encodings results:

Code - C#: [Select]

1. Int32 b;
2. List<Byte> bytes = new List<Byte>();
3. while ((b = proc.StandardOutput.BaseStream.ReadByte()) != -1)
4.     bytes.Add((Byte) b);
5. // Look for each encoding...
6. // I look in parts
7. Int32 skip = 120; // I have tried the next values: 0, 20, 40, 60, ..., 120
8. Int32 take = 20;
9. Int32 count = Encoding.GetEncodings().Length; // 140
10.  
11. foreach (EncodingInfo item in Encoding.GetEncodings().Skip(skip).Take(take)) {
12.     Encoding x = item.GetEncoding();
13.     Byte[] bytes2 = Encoding.Convert(Encoding.GetEncoding(codepage), x, bytes.ToArray());
14.     outputText = x.GetString(bytes2);
15.     if (doc != null) {
16.         if (printMsg) {                        
17.             doc.Editor.WriteMessage("\nEncoding: {0}, CodePage = {1}\n", x.EncodingName, x.CodePage);
18.             doc.Editor.WriteMessage(outputText);
19.             doc.Editor.WriteMessage(Environment.NewLine);
20.             doc.Editor.WriteMessage(new String('*', 20));                        
21.         }
22.     }
23. }
24.  

But I receive incorrect result always.
Where is the problem?

[Andrey Bushman]

I found the reason of problem:

Code - C#: [Select]

1.             String _args = sb.ToString();
2.             String exeName = new FileInfo(Path.Combine(curDir, @"..\..\recovery")).FullName;
3.             Process proc = new Process();
4.             ProcessStartInfo info = new ProcessStartInfo();
5.             info.CreateNoWindow = true;
6.             info.RedirectStandardOutput = true;
7.             info.UseShellExecute = false;
8. #if acad2013
9.             Int32 codepage = 866; /* The CultureInfo.CurrentCulture.TextInfo.OEMCodePage in the
10.                                    * AutoCAD 2013 Enu returns 437 (OEM United States). It is
11.                                    * invalid encoding. */
12. #else
13.             Int32 codepage = CultureInfo.CurrentCulture.TextInfo.OEMCodePage;//866 (Cyrillic (DOS))
14. #endif
15.             info.StandardOutputEncoding = Encoding.GetEncoding(codepage);
16.             info.FileName = exeName;
17.             info.Arguments = String.Format("{0} -clear", _args);
18.             info.WorkingDirectory = new DirectoryInfo(Path.Combine(curDir, @"..\..\")).FullName;
19.             proc.StartInfo = info;
20.             Encoding enc2 = Encoding.GetEncoding(866);
21.             proc.Start();
22.  
23.             String outputText = String.Empty;
24.             outputText = proc.StandardOutput.ReadToEnd();
25.  
26.             if (doc != null) {
27.                 if (printMsg) {
28.                     doc.Editor.WriteMessage(outputText);
29.                     doc.Editor.WriteMessage(Environment.NewLine);
30.                     doc.Editor.WriteMessage("&#1054;&#1087;&#1077;&#1088;&#1072;&#1094;&#1080;&#1103; &#1079;&#1072;&#1074;&#1077;&#1088;&#1096;&#1077;&#1085;&#1072;."); // Operation is complete (ru-RU)
31.                     doc.Editor.WriteMessage(Environment.NewLine);
32.                 }
33.             }
34.  

Problem is solved
