Sets the lower and upper limits for the number of items in the operation, and the flags that control how progress information is calculated for the operation.
Service providers call the IMAPIProgress::SetLimits method to set or clear the MAPI_TOP_LEVEL flag and to set local and global minimum and maximum values. The value of the flag setting affects whether the progress object understands the minimum and maximum values to be local or global. When the MAPI_TOP_LEVEL flag is set, these values are considered global and are used to calculate progress for the entire operation. Progress objects initialize the global minimum value to 1 and the global maximum value to 1000.
When MAPI_TOP_LEVEL is not set, the minimum and maximum values are considered local, and providers use them internally to display progress for lower level subobjects. Progress objects save the local minimum and maximum values only so that they can be returned to providers when the IMAPIProgress::GetMin and IMAPIProgress::GetMax methods are called.
