posted July 3, 2002 2:06 PM I’ve created a .NET class that implements your .NET FTP assembly. Everything works fine when I call this.NET class from another .NET application. BUT, when I call my .NET class from a COM application, I get the following error: Cannot load type Dart.PowerTCP.SegmentedStream, Dart.PowerTCP.Tcp, Version=2.0.0.1, Culture=neutral, PublicKeyToken=5966291b8955e4bb. I've also included a licenses.licx file in my .NET class that uses PowerFTP.Net Any idea why? Thanks |

posted July 3, 2002 4:28 PM More info: This is the method that bombs. I don't know which exact line. Must likely the Put statement. Dim Ftp1 As New Dart.PowerTCP.Ftp() Ftp1.Server = mServer ' Substitute your server here. Ftp1.Username = mUserName ' Substitute your username here. Ftp1.Password = mPassword ' Substitute your password here. Dim ms As New MemoryStream() Dim sw As New StreamWriter(ms) sw.Write(sBody) sw.Flush() 'ms.Position = 0 Dim dir As String Try Dim sFullPath As String = mDirectory + "/" + mFileName Ftp1.Put(ms, sFullPath) Catch err As Exception Throw New Exception(err.Message) Exit Sub End Try |

posted July 3, 2002 4:42 PM Check the .NET project and make sure that Dart.PowerTCP.TCP.dll is added as a reference. It most likely is, since it finds it in the Common Files\Dart\DotNetDLLs directory which is in the search path defined in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders The COM project probably can't see the DLL since it is not aware of this directory. I think that you either need to copy both DLL's (Dart.PowerTCP.FTP and Dart.PowerTCP.TCP to the same directory where your COM app is, or register both DLL's in the GAC using gacutil: gacutil /i <path to dll> |

posted July 3, 2002 5:01 PM I registered the Dart DLLs in the GAC. I now get a new error: Attempted to call a method declared on type Dart.PowerTCP.SegmentedStream on an object which exposes Dart.PowerTCP.SegmentedStream. Thanks |

posted July 3, 2002 5:17 PM Please create a simplified version of what you are trying to do and email it to support@dart.com. I want to make sure we are working with the exact same scenario, so I will need source code that I can compile here. Make sure you include both the project that uses our DLL's and and project that uses the new class. Again, please make sure that what you send is very simple and only contains what is absolutely necessary to demonstrate the problem. Reference Forum Issue 2139 in the subject of the message. |

posted July 5, 2002 1:47 PM It seems that putting them in the GAC was the trick... BUT, it didn't work right away. In fact, I did a reboot, and it still didn't work after putting it in the GAC. But then, all of a sudden, it started working. As if there was some sort of cache that got unloaded. |
