• Formatting numbers with significant figures in C#

  - by Chris Farmer

  I have some decimal data that I am pushing into a SharePoint list where it is to be viewed. I'd like to restrict the number of significant figures displayed in the result data based on my knowledge of the specific calculation. Sometimes it'll be 3, so 12345 will become 12300 and 0.012345 will become 0.0123. Occasionally it will be 4 or 5. Is there any convenient way to handle this?

  - by SpikETidE

  I am trying to learn OOP in PHP, and I have some confusion about interfaces and abstract classes. They both contain no implementations, only definitions, and should be implemented through their sub-classes. What part of abstract classes clearly distinguishes them from interfaces? Also, due to their apparent similarities, based on what reasons should I decide to use one over the other?

SELECT sa.OrderName, sa.OrderType, pr.Volume_UOM ,pr.Length_mm*pr.Width_mm*pr.Height_mm AS Volume_Cubic ,pr.Length_mm*pr.Width_mm AS Volume_Floor ,pr.Length_mm ,pr.Height_mm ,pr.Width_mm FROM CostToServe_MCB.staging.Sale sa LEFT JOIN staging.Product pr ON sa.ID = pr.ID

  In my application I'm dynamically adding new TdxBarSubItems based off of a SQL query. In some cases the result set is rather large so the menu fills the entire screen and sometimes has a down arrow to scroll the list. In a previous version of the code before switching to Dev Express, I was able to add TMenuBreak objects to make the list divide into columns. Is there a way to do this with Dev Express components?

  The question is probably better answered by how do I get value == displayedValue. Or how do I prevent value to be Index based and instead use the textstring I provide from my store. My Json has this structure: {"items":[{"zipcity":"Stocka"},{"zipcity":"Stockamöllan"},{"zipcity":"Stockaryd"}]} Does it need to change?

• virtual keyword in different scenarios

  - by Mahesh

  I figured out 2 different meanings for virtual based on the situation it is being used. If a baseClass has a function defined virtual, then the derivedClass is going to override the function. The baseClass::~baseClass() should be defined virtual, if there is any class derived from it. Here it means, the derived class destruction first takes place followed by base class destruction. Are there any other situations where virtual hold a different meaning ?
