/* File: details.cpp
Description: Contains definition for class DetailsView. This class implements a list view containing quota information about the various accounts in a volume's quota information file.
Revision History:
Date Description Programmer -------- --------------------------------------------------- ---------- 08/20/96 Initial creation. BrianAu 05/28/97 Major changes. BrianAu - Added "User Finder". - Added promotion of selected item to front of name resolution queue. - Improved name resolution status reporting through listview. - Moved drag/drop and report generation code from dragdrop.cpp and reptgen.cpp into the DetailsView class. DetailsView now implements IDataObject, IDropSource and IDropTarget instead of deferring implementation to secondary objects. dragdrop.cpp and reptgen.cpp have been dropped from the project. - Added support for CF_HDROP and private import/ export clipboard formats. - Added import/export functionality. 07/28/97 Removed export support for CF_HDROP. Replaced BrianAu with FileContents and FileGroupDescriptor. Import from CF_HDROP is still supported. Added Import Source object hierarchy.*////////////////////////////////////////////////////////////////////////////////

// Add/remove from this array to change the columns in the list view.
// IMPORTANT:
// The ordering of these items is very important (sort of).
// Because of a bug in commctrl.h, they don't paint under the bitmap
// if it's the only thing in the column (or if it's the bitmap of the primary
// item). Also, the behavior of the listview is such that the text in
// subitem 0 is always shifted right the width of a small bitmap. When
// I had the status column NOT as item 0, there were two display problems.
// 1) First, the text in column 0 was always shifted right to allow for the
// bitmap we weren't using. This looked funny.
// 2) The full-row-select highlight didn't properly paint the background
// of the status bitmap.
//
// By placing the status column as subitem 0, we eliminate problem 1 since
// we're using a bitmap in subitem 0 (listview's default behavior).
// If we drag the status column out of the leftmost position, they still don't
// paint under the bitmap but at least it will work like any other explorer
// view. When/if they fix listview, we'll be fixed automatically.

/* Function: DetailsView::CreateListViewToolTip
Description: Creates a tooltip window for displaying the user's folder name when the Folder column is hidden. The entire listview is defined as a single tool. We make the tooltip control think each listview item is a separate tool by intercepting WM_MOUSEMOVE, and performing a hit test to determine which listview item is hit. If the cursor has moved over a new item, the tooltip control is sent a WM_MOUSEMOVE(0,0). The next real WM_MOUSEMOVE that we relay to the tooltip makes it think that it is on a new tool. This is required so that tooltips popup and hide appropriately.

Arguments: iRow - Row where to begin search for next selected item in listview. For the first call, specify -1 to begin the search with the first item. Subsequent calls should specify the value returned from the previous call to GetReportItem.
iColId - Item's column ID (idCol_Folder, idCol_Name etc).
pItem - Address of an LV_REPORT_ITEM structure. This structure is used to return the data to the caller and also to specify the desired format for numeric values. Some report formats want all data in text format (i.e. CF_TEXT) while other binary formats want numeric data in numeric format (i.e. XlTable).
Returns: TRUE = Retrieved row/col data. FALSE = Invalid row or column index.

ppUser - Address of an interface pointer variable to receive the IDiskQuotaUser interface for the user object at index 'i'.
piItem - Address of integer variable to receive the Listview item index of the object at index 'i'.
Returns: TRUE = Returned information is valid. FALSE = Couldn't retrieve entry 'i'.

/* Function: DetailsView::Importer::Import [Source&]
Description: Imports settings for one or more users from a Source object. All import functions eventually get their information into a Source object format and call this function. It then separates out the individual user information and calls ImportOneUser() to do the actual import.
Arguments: source - Reference to Source containing user import info.
Returns: Number of users imported.

/* Function: DetailsView::Importer::Import [LPBYTE, LONGLONG, LONGLONG]
Description: Imports a single user into the system given the user's SID and quota settings. This is the single function where all import mechanisms end up. It does the actual importing of the user.
Arguments: pbSid - Address of buffer containing user's SID.
llQuotaThreshold - User's quota warning threshold setting.
llQuotaLimit - User's quota limit setting.
Returns: -1 = User pressed "Cancel" in either the "Replace User" dialog or in the progress dialog.
0 = Failed to import user.

Description: Returns the HWND of the topmost window in the importer UI. If the UI's progress dialog is visible, the dialog's HWND is returned. Otherwise, the value of m_hwndParent is returned. The Importer uses this function to identify what window should be parent to any error message boxes.
Arguments: None.
