• [game] How is it possible to legally write ::: in C++ and ??? in C#?

  - by daveny

  These questions are a kind of game, and I did not find the solution for them. It is possible to write ::: in C++ without using quotes or anything like this and the compiler will accept it (macros are prohibited too). And the same is true for C# too, but in C#, you have to write ???. I think C++ will use the :: scope operator and C# will use ? : , but I do not know the answers to them. Any idea?

• Extended MAPI: How to get the entry ID of messages moved by CopyMessages

  - by marijne

  I have found that if I move a message using IMAPIFolder::CopyMessages (using the MESSAGE_MOVE flag) the message gets a new entry ID. However I do not see any reliable way of getting the entry ID of the message in its new location, or otherwise getting a reference to it. The best suggestion I have had so far involves tagging the message with the old custom property before moving, and then doing a search afterwards, but I was wondering if there is a less convoluted solution.

• How to insert an image into a PolygonMorph?

  - by hanneswurstes

  I need to get a texture into a PolygonMorph, but these seem to require an InfiniteForm as color/ filling. The InfiniteForm is no solution as i need to rotate the PolygonMorph later on and moving the PolygonMorph around also has sideeffects on the displayed texture. It would be very useful if it would be possible to scale the inserted texture as well. How would you do this without replacing the existing PolygonMorph (or at least keeping the PolygonMorph's shape)?

• How to animate the change of image in an UIImageView?

  - by mystify

  I have an UIImageView with an image. Now I have a completely new image (graphic file), and want to display that in this UIImageView. If I just set myImageView.image = newImage; the new image is visible immediately. Not animatable. I want it to nicely fade into the new image. I thought maybe there's a better solution than just creating a new UIImageView on top of that and blending with animation?

• Any way to check if an assembly is a framework assembly, in .Net, other than checking the name for '

  The title says it all. Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution. Alternatively, if that's not possible, how about checking the modules in an assembly?

• Sum and average over null values SQL Server 2008 Analysis Services

  - by Jonathan

  I have a simple problem, I think, but I have googled and can't find the solution. I have a cube that has MeasureA, MeasureB and MeasureC. Not all three measures have values for each record, sometimes they can be null, it's depending if it was applicable. Now for my totals, I need to average but the average must not take nulls into account. Any help will be much appreciated. When I view the measures, the null values show as zeros.

If so, can we specify this pattern in the config file? Looking for the solution in C# Thanks

• PHP: parse URL for matching directory /somedirectory/ and execute conditional code

  - by Scott B

  This has to be pretty simple, but I'd like to parse the current URL and execute conditional code depending on whether the user is on the /sitemap/ directory. So for example, if the site is example.com, and if the request is example.com/sitemap/. Then I want to execute conditional code in that case. I'm using wordpress so I'm not sure if there is a built-in function that gets this... A pure PHP solution is fine.
