Use this property to return the number of elements in the SimpleList object.
Definition
HRESULT ISimpleList::get_Count(long*Count);
Parameters
Count
[out, retval] A pointer to a long used to return the number of items in the SimpleList.
Return Values
This method returns an HRESULT indicating whether or not it completed successfully. See the Error Values section for more details.
Error Values
This method returns S_OK (0x00000000) to indicate success and standard COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors. Additional information may be available using the global Err object, which can be accessed using the API function GetErrorInfo. In particular, the GetDescription method of the IErrorInfo interface may return a text description of the error.
Remarks
The Count parameter points to valid data only if the method completes successfully.
The caller should always call this method before calling a SimpleList method that requires an array index in-value as a parameter (such as the Delete method).
