07-28-2008, 2:53 AM Yesugey Joined on 07-28-2008 Turkiye Posts 8 oField gives NullReferenceException Attachment: errr.JPG I have a little problem with main ASP.NET example of DynaCube. You know the example is simply creating a cube, saving it and showing it on the webpage. My cube cannot be created, when i commented out the try-catch parts, i getting this error: "oField" needs Constructor to be used, but i cant create one because it have no constructor anyway. I bet some of you guys saw this error before.   I converted for VS2005 myself, if anyone have a sample for how to use DynaCube in VS2005, it will be great help.    Report

This KB article should be helpful: http://www.datadynamics.com/forums/97491/ShowPost.aspx Also, I've attached a simple sample which shows how to use DynamiCube3 in VB 2005. Install DynamiCube 3.3.0.1215, install DynamiCube primary interop assembly and open this sampple in VB 2005. Thank you, Andrey T.    Report

I already installed the .bat file you gave me. But i forgot to tell you it is not Windows application, it is a Web Site i want to create. I sent you the source code as an attachment. The code is simply creating a cub file first, then showing it on the webpage. I commented out the try-catch part of it, so you will be able to see the nullReference error..    Report

Sample works fine for me now. Please see the attachment. Thank you, Andrey T.    Report

07-29-2008, 5:07 AM Andrey - DD Joined on 08-01-2007 Russia, Novosibirsk Posts 561 Re: oField gives NullReferenceException Attachment: dcUtil.zip Yesugey, I recommend you to take the following steps: Uninstall DynamiCube3 from your system, make sure all instances of DCube3.ocx and DynamiCube.Interop.dll are deleted. Install the latest DynamiCube3 3.3.0.1215 build again. Install the DynamiCube 3.0 Primary Interop Assembly in the global assembly cache (GAC): http://www.datadynamics.com/forums/97491/ShowPost.aspx (Unzip the attached file to C:\Program Files\Data Dynamics\DynamiCube3 (where DynamiCube.Interop.dll and Install DynamiCube Primary Interop Assembly.bat files are located) and run .bat file again.) Run Visual Studio 2005 and open sample. Thank you, Andrey T.    Report

Also installed Global Assembly Cache. And i noticed you attacked 2 .exe files in your last post, i executed them too. Now i building your sample, i getting this new error: Maybe i did not implemented your sample well, but my boss intalled DynaCube again on his computer also, and we getting both same errors. What we do wrong to take same errors on two different computers? I bet it is about our dll references, but i need your opinion.    Report

07-31-2008, 3:30 AM Yesugey Joined on 07-28-2008 Turkiye Posts 8 Re: oField gives NullReferenceException Hi ericc; I always tried to add the DynaCube Reference, from "COM Components". Today i just selected "Browse", and found "DynamiCube.Interop.dll" on the Common Files. So now i managed to run the Andrey's sample. Thanks for your and Andreyy's help :)        Report
