• .NET Development Exposing .NET classes to a Scripting Host

  Currently I am transfering an application from C++ to C# (i.e. rewriting) that creates an instance of the Microsoft Scripting Host, like in the sample " MfcAxscrVb ". (You know, such stuff like the IActiveScriptSite interface, etc.) An issue that arrises is when exposing C#-objects to the scripting host that are derived from generic classes (e.g. a class derived from List<T> ). When trying to access an instance of such a class from my VB script, the methods I try to call seem to be unavailable ("method not found"). Question: Is this a known "issue" that objects derived from generic classes cannot be exposed to and consumed from a script inside the Microsoft Scripting host Thanks Uwe If it is a g ...Show All

• SQL Server Problems Deleting / Renaming Dimensions

  I had a problem with a dimension and so decided to re-created it. Once I was happy with the new dimension I deleted the old and renamed the new to what the old one was called previously. When I try and build my cube I get the following error: Error 18 Errors in the metadata manager. The dimension with the name of 'dim_product' already exists in the 'Sales_AS' database. Not sure why this is happening as I thought I'd got rid of all trace of the old dimension. If I rename the new dimension I have no problem. Is anyone able to explain what's going on here Thanks. If you deploy with the default settings the old dimension still exists on the server and if you want too deploay a second one with t ...Show All

• Software Development for Windows Vista WPD Api Sample failing to return Device Count

  Hi Experts, I am having an issue with the WPD Api sample provided with Windows Vista SDK and I am running the application in Windows XP. I am trying to identify a WIA device via the IPortableDeviceManager interface. I tried with IWIADeviceManager interface earlier but switched to the former since thumbnail full path method calls were not returning proper results. I could compile the WPD Api Sample workspace and could successfully register the Interface, IPortableDeviceManager interface, but the same returns 0 devices when i call: hr = pPortableDeviceManager->GetDevices(NULL, &cPnPDeviceIDs); I have connected the camera in PTP mode and not in USB mode. Any ideas or hints on why this is happening Or is there a ...Show All

• SQL Server Security setup for distributed queries

• SQL Server SSIS Higher Level Edition error when run in a Sql Job

  Hi, I am receiving the following error in Sql Job agent when I try to run an SSIS package : The task "Create Excel File" cannot run on this edition of Integration Services. It requires a higher level edition. It then goes on to tell me : The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. I have tried reseting the error count to allow for the "errors" , but it stills fails.

• SQL Server Transactions - Back to Basics

  Hi all, I am having no end of trouble with transactions in the package which i am building. I now just want to go back to basics and see if someone can tell me where i should set specific transaction options. Firstly, my package runs a for each loop which loops through a directory of directories. In each of the sub directories there are 2 files. The first steps in the loop are to check if a folder has been processed previously, if so then it moves it to a specified directory. The reason that this is done first is that i cannot move the directory whilst it is being read in the foreach loop, so i pass the path to the next iteration of the loop. There is another file system move directory task outwith the foreach loop to deal with the last di ...Show All
