Int64 minus....

[Thilek]

Hi guys, I have a question ya... minus a int64 with another int64.. below is my coding :-

System::Int64^ limit1;
System::Int64^ limit2;
System::Int64^ diff;

   diff = limit1-limit2;

the limit1 and limit2 values are the count of the records in a database. but the diff-limit1-limit2; is not working. i am new to managed c++.kindly help me... Regards, Thilek

Either of these should work:

System::Int64 limit1 = 100;
System::Int64 limit2 = 25;
System::Int64 diff = limit1 - limit2;

System::Int64^ limit1 = gcnew System::Int64(100);
System::Int64^ limit2 = gcnew System::Int64(25);
System::Int64^ diff = gcnew System::Int64(\*limit1 - \*limit2);

System::Int64 is a value type, so if you want to use handles to a value type (e.g. System::Int64^) then you need to create objects on the managed heap. Mark

Don't use handles on value types.
