System.IO.DirectoryNotFoundException: 0x80070003 from UltraDockManager.LoadFromXML
posted

Hi

I'm having a problem deploying an application I have written which uses the UltraDockManager.LoadFromXML command to restore the document layout previously saved to SQL server 2000.  The procedure works fine on my development machine but the compiled version errors when deployed on the server, with: System.IO.DirectoryNotFoundException: The system cannot find the path specified. (Exception from HRESULT: 0x80070003) when it tries to execute the line: objUltraDockManager.LoadFromXML(objFileStream).objUltraDockManager is the control on the form.  objFileStream is a system.io.memorystream object. Because I’m loading from a file memory stream, I have no idea why the objUltraDockManager would be looking for a path or what path it is looking for. Additionally, this code works perfectly on my development machine both in debug and compiled.  It loads the form layout from the database as intended. I am using Infragistics2.Win.UltraWinDock.v8.2.dll from the NetAdvantage collection. 

Do I need to do something extra for the ultradockmanger, when compiling for release? 

Why does this object need a path when it is using a stream?

Is it a temp path, if so what path is it, and how do I configure it?

Any help greatly appreciated.PenPal1999.

    Hi

    I've solved the problem now. It was simply a bad copy of the dot net framework on the server. I created an installation package for my application and when I tried to install it on the server, it requested that I installed framework 3.5 (which was already on the server, so somthing must have been wrong with it). When the application finally installed the layout works as it should.

    I'll try and blog my load and save routines soon.

    Regards
