Returns the maximum number of items in the operation for which progress information is displayed.
HRESULT GetMax(
ULONG FAR * lpulMax
);
Parameters
- lpulMax
[out] A pointer to the maximum number of items in the operation.
Return Value
- S_OK
The maximum number of items in the operation has been retrieved.
Remarks
The maximum value represents the end of the operation in numeric form. The value can be a global maximum value, used to represent the scope of the entire progress display, or a local value, used to represent only a part of the display.
The value of the flag setting affects whether the progress object understands the maximum value to be local or global. When the MAPI_TOP_LEVEL flag is set, the maximum value is considered to be global and is used to calculate progress for the entire operation. When MAPI_TOP_LEVEL is not set, the maximum value is considered to be local, and providers use it internally to display progress for lower level subobjects. Progress objects save the local maximum value only to return it to a provider through a GetMax call.
For more information about how and when to make calls to a progress object, see How to: Display a Progress Indicator.
Notes to Implementers
Initialize the maximum value to 1000. Service providers can reset this value by calling the IMAPIProgress::SetLimits method. For more information about how to implement GetMax and the other IMAPIProgress methods, see Implementing a Progress Indicator.
