To measure the actual power consumption you should use add an electricity meter to your power supply (remove the batteries if using a notebook). Note that you will measure the power consumption of the entire system, so make sure to avoid nuisance parameters (any other system activity, i.e. anti-virus updates, graphical desktop environment, indexing services, … Read more
You can always use the normal C# tools to do this. However, if the entire purpose is to make a nice string for binding, you may be able to use the binding’s StringFormat directly. For example, you can have a TextBlock like so: <TextBlock> <TextBlock.Text> <MultiBinding StringFormat=”{}{0} at distance of {1}m.”> <Binding Path=”User”/> <Binding Path=”Distance”/> … Read more
I think that the namespaces of the two projects differ, so this is why it isn’t working. Try making a dynamic link library which contains that class, and use the same library in both projects. This way, you can also modify the class in one project, it will be modified automatically in the second project. … Read more

Only by addition and subtraction… Simply add numbers from 1 and check whether the sum is the given number. In pseudocode. Given 5050. number := 5050 next, sum := 0 while sum <= number next := next + 1 sum := sum + next return next 3 solved How to get the n if I … Read more
When you call round() with double agrument you actually call: double round(double x); from <cmath> not your version hence the error. If you rename your function error would be gone without cast. Yet another reason to avoid using namespace std. 1 solved C++ function returning wrong data type
