• .NET Development multithreading issue - please help

  Hi, I'm having big issues using multithreading. As it is quite difficult to explain I've made a sample application to illustrate my problem: http://graphicsxp.free.fr/WindowsApplication11.zip It starts a new thread, which DoWork function calls a delegate to do do operations on controls (tabcontrol, datagrid....) There is also a popup that contains a progressbar to show the progress in real-time. The problem is that updating the progressform in the delegate does not work, so I can only update the progressform before or after calling the delegate, which is pointless as progress should be updated as operations on control are being ...Show All

• SQL Server Virtual Cube Migration

  What are best practices around virtual cube migration When the cube was migrated, it became a physical cube with linked measure groups. However, when I try and add a dimension to the cube, and edit the granularity within the Dimension Structure tab, I get this. Regular relationships in the current database between non-linked (local) dimensions and linked measure groups cannot be edited. These relationships can only be created through the wizard. This dialog can be used to delete these relationships. What's the purpose of a linked measure group if I cannot add a dimension to the same cube What wizard Andrew, Bas ...Show All

• .NET Development IIS And Impersonation - accessing file shares?

  hi all, i have two servers, one web server (called WS01) and a file server (FS01). I have a new drive on FS01 and i want to store my uploads to it. The problem is that the two servers are separated, they are located in the same place, and can see each other via private ip addresses but are not on a windows network together, so they dont share user accounts. I was testing the sites on our servers and discovered that i can't get into the storage on FS01 even using identity impersonate = true. I tried a workaround i found on ASP Alliance ( http://aspalliance.com/336 ) but cant get it to work i managed to create a virtual dir on ...Show All
