GotCAL.CSideInstaller Source<\/h1>\n

(note this is a post in progress, please post comments etc.)<\/p>\n
This is the second part of Dynamics NAV and the ROT Table, which was posted in december 2007. In this article i will discuss some of the uses of the interfaces, and also give give you access to the sourcecode for a simple application created in Visual Studio 2005.<\/p>\n
First off let’s take a look at the Interface for the NSObjectDesigner class:<\/p>\n
\nIObjectDesigner.cs:\nnamespace GotCAL.CSIDEInstaller\n{\nusing System;\nusing System.Runtime.InteropServices;\nusing System.Runtime.InteropServices.ComTypes;\n[ComImport, Guid("50000004-0000-1000-0001-0000836BD2D2"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]\ninternal interface IObjectDesigner\n{\n[PreserveSig, DispId(1)]\nint ReadObject([In] int objectType, [In] int objectId, [In] IStream destination);\n\n[PreserveSig, DispId(2)]\nint ReadObjects([In] string filter, [In] IStream destination);\n\n[PreserveSig, DispId(3)]\nint WriteObjects([In] IStream source);\n\n[PreserveSig, DispId(4)]\nint CompileObject([In] int objectType, [In] int objectId);\n\n[PreserveSig, DispId(5)]\nint CompileObjects([In] string filter);\n\n[PreserveSig, DispId(6)]\nint GetServerName(out string serverName);\n\n[PreserveSig, DispId(7)]\nint GetDatabaseName(out string databaseName);\n\n[PreserveSig, DispId(8)]\nint GetServerType(out int serverType);\n\n[PreserveSig, DispId(9)]\nint GetCSIDEVersion(out string csideVersion);\n\n[PreserveSig, DispId(10)]\nint GetApplicationVersion(out string applicationVersion);\n\n[PreserveSig, DispId(11)]\nint GetCompanyName(out string companyName);\n}\n}<\/pre>\nas you can see we import the COM library, which we discovered in the registry. In the registry it shows it has 14 methods, so far i only know 11 of them. These were found using reflection on the Celenia Version Control software, and it is also the way (i guess!) the Developers Toolkit can extract the ojbects through the CSide Client.<\/p>\n
Most of the methods are very simple, and just return a string, and thus they are very easy to implement, eg.:<\/p>\n
\npublic string GetDatabaseName()\n{\nstring databaseName;\nint num = this._objectDesigner.GetDatabaseName(out databaseName);\nreturn databaseName;\n}<\/pre>\nAs most of you who have been playing around with this after the first post have discovered the biggest issue, is reading and writing the streams that holds the actual objects. At first I used “AuthHelper.dll” a library that somehow could handle the reading and writing of streams. But here is a StreamSupport class that handles it in .NET:<\/p>\n
\nnamespace GotCAL.CSIDEInstaller\n{\nusing System;\nusing System.IO;\nusing System.Runtime.InteropServices.ComTypes;\n\npublic class StreamSupport\n{\npublic static unsafe IStream ToIStream(Stream stream, ref IStream comStream)\n{\n\nbyte[] buffer = new byte[stream.Length];\nstream.Read(buffer, 0, buffer.Length);\nuint num = 0;\nIntPtr pcbWritten = new IntPtr((void*) &num);\ncomStream.Write(buffer, buffer.Length, pcbWritten);\nreturn comStream;\n}\n\npublic static unsafe MemoryStream ToMemoryStream(IStream comStream)\n{\nMemoryStream stream = new MemoryStream();\nbyte[] pv = new byte[100];\nuint num = 0;\nIntPtr pcbRead = new IntPtr((void*) &num);\ndo\n{\nnum = 0;\ncomStream.Read(pv, pv.Length, pcbRead);\nstream.Write(pv, 0, (int) num);\n}\nwhile (num > 0);\nreturn stream;\n}\n}\n}<\/pre>\nHope to get some feedback from all you out there, please post a comment, idea, or just a quick hello.<\/p>\n

Here are some of the old comments for the blog posts:<\/p>\n

After switching blogging software, due to a server crash i never really got the old posts reposted from the original blog. I have had a lot of requests for one particular post: Dynamics NAV and the ROT table. I started finding the old backup of the database, to restore the post and realized it is almost 3 years old. Cant believe how fast times goes by. But after reading the very interesting post from Waldo about their new tool ReVision i came to think of this old post. (unfortunately i will not be at Directions in San Diego myself, even though i just live a couple of hours from there! But i hope to get some updates from people seeing the tool demonstrated!).<\/p>\n![\"\"](\"http:\/\/45.63.48.66\/wp-content\/uploads\/2010\/10\/registryentries_50000004.png\" "\\"registryentries_50000004\\"")
