How to multiply only not null values in rdlc report expression -


How to multiply two values ​​when RDLC report does not tap into expression

I use this

= SUM (field! Quantity value * field! Unique value. Value)

it has been changed, but the value is also zero If value is zero

= even ((IIF (field! Quantity value is nothing, 0, field! Quantity value)) * (IIF (field! Unique origin) Other. Money is nothing, 0, Fields! Exclusive purse. Thanks in advance for Vail)))

Help.

you

for example you can modify your expression like this : 

  = yoga (IIF (field! Quantity value is nothing, CDCE (0), CDBL (field! Volume value)) * IIF (Fields! CDBL (0), CDE (Fields! Exclusive Pars. Value)))   
 This is a 'compressed' version:  
  = Sum ( IIf (do not have anything (field! Quantity. Uly * Field! Unique value. Value), Seedibiel (field! Quantity. Price * Field! Unique value. Value), Seedibiel (0))

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace.
