• Visual C# Where do I find information on the ^ operator in regards to its use in "stream^ stream"

  public : DeflateStream ( Stream ^ stream, CompressionMode mode, bool leaveOpen ) I know it isn't an XOR. But searching through the language ref I can't fine it easily. Thanks for any help. jonnic This is the C# forum, are you using C# or C++ I ask because I believe that the ^ is used to denote a managed 'pointer'. I don't think it's used in C#. ...Show All

• SQL Server Filter parameter based on prior parameter

  Hi guys, i have some report parameters that are dropdowns, and i would like to use whatever is selected in them to filter subsequent dropdowns. I know that the report designer automatically makes parameters dependant on each other, but that has been stripped out of the rdl, i need to replace it with more targeted filtering. So assuming that parameter A and parameter B get their values from a dataset, how can i filter parameter B's contents based on parameter A I am quite happy to tweak the rdl if that is what is required. Thanks, sluggy Hi Sluggy, Not sure if I've got the best answer - but I h ...Show All

• Visual Studio Design-time Reflection

  I have created several type editors that require design-time reflection in order to accomplish their tasks.  Using methods from the System.Reflection namespace works perfectly until the code is changed thereby modifying the type.  After the code change, I have to rebuild the solution and restart Visual Studio before the reflection is up-to-date again. I know there must be a way to gether reflection information at design-time (intellisense doesn't require you to rebuild and restart VS before it can be used).  I've downloaded the October VSIP SDK and have been trying to gain access to the VsObjectModel, but I cannot seem to enu ...Show All
