casting problems for int
-
unsigned int it = V_INT(&PhysicalMemoryVal);Does this actually make sense here or is there some problems with the pointers We have a mathematician, a different kind of mathematician, and a statistician! -
Interesting. What is PhysicalMemoryVal? Looks like you are casting its memory address, not what is occupied in memory. kuphryn
Thats what I tought, how do I get the proper value please???? Oh by the way PhysicalMemoryVal is the amount of memory the operating system has available, you get it from WMI classes We have a mathematician, a different kind of mathematician, and a statistician!

Given that PhysicalMemoryVal is a memory address, one possible solution is pointer. unsigned int *pValue = PhysicalMemoryVal; Kuphryn
no good, now I get and error error C2440: 'initializing' : cannot convert from 'INT' to 'unsigned int *' But I dont understand because I use another function in the same way only it return a 16 bit int and there seems to be no problem there We have a mathematician, a different kind of mathematician, and a statistician!

Actually!!!! how do i declare a 64 bit int???????? uint64????? We have a mathematician, a different kind of mathematician, and a statistician!

PhysicalMemoryVal? Your code will only work if it is aVARIANT.

Yes PhysicalMemoryVal is a VARIANT The value returns something, but its a negative number which doesnt make any sense http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wmisdk/wmi/win32_operatingsystem.asp at this website you will find a
uint64 FreePhysicalMemoryIm trying to plot this against anothervalue uint64 TotalVisableMemorySizebut the values Im getting are way out My GetProperty method for getting the values works fine, because I have it fetching another value without any problems. -
