I am using the method in the .net framework method Graphics->getHDC(); to get the device context of a windows form. This returns an IntPtr which I convert using the following line HDC myhdc = (HDC) (void*) myIntPtr; When I place a watch on the variable I get the following {HDC__} { unused=<undefined value> } as its value. Note that when I define the HDC as a member variable of a class, I get a valid value. When it is defined local to a method, I get the above undefined value. Has anyone come across something similar or know of a solution?
