• Evenly distibuted scatterViewItems that dont overlap

  - by Christo Fur

  Hi I have an app that creates a variable number of ScatterviewItems based on which tagged object is placed on the surface table. The ScatterViewItems are added programatically to the ScatterView based on info looked up in a DB The Scatterview does a good job of displaying this info However, I would like them to be evenly distributed across the table and not have any items overlapping Any ideas how to do that?

  Hey guys, I'm writing a search algorithm in C++, and one of the things I need to do is have a few if statements that check cells above, below, left of, and right of. Each time a cell is found to be open and added to the stack, I want it added to a list of cells already checked. I want to be able to say in the if loop if(thisCell is not in checkedCells). Any simple ideas? Thanks!

• Flash causing crash in embeded browser

  - by Lodle

  For my work project we recently switched from visual studio 2008 to 2010 and we use an embedded instance of firefox to render webpages. The only problem we are having is that flash seems to crash the application. It seems that instead of linking dynamically to the runtime it needs its using the new 2010 one and is having issue with new and delete. Any ideas on how to fix instead of switching back to 2008?

• Cross-Domain iframe communication

  - by Chris

  I have an iframe being created on a page, and the page's domain is being explicitly set to 'xyz.com' but the iframe's domain is defaulting to 'dev.xyz.com', which is the actual domain i'm developing for. The problem is, when I try to access that iframe via iframe.contentWindow.document, it fails due to the difference in domain. I've tried setting the iframe's src to a file with document.domain = 'xyz.com' but that doesn't seem to be doing the trick... Any ideas?

  Hi, I would like to overload the (/) operator in F# for strings and preserve the meaning for numbers. /// Combines to path strings let (/) path1 path2 = Path.Combine(path1,path2) let x = 3 / 4 // doesn't compile If I try the following I get "Warning 29 Extension members cannot provide operator overloads.

• ibatis/Oracle - SELECT query inside INSERT is failing

  - by whoopy_whale

  Hi, I'm trying to do an Insert operation using iBatis. INSERT INTO SCHEMA.TABLE (FIELD1, FIELD2, FIELD3) VALUES (#field1#, (SELECT ANOTHER_FIELD FROM SCHEMA.TABLE WHERE FIELD4= #field2#), #field2#) The inner select query always fails and returns NULL. But if I substitute #field2# with the actual value only in the inner query, it works fine. Why is iBatis not substituting fieldvalues in the innerqueries? Any ideas?
