NIM: Selection Issues
Credentials selection in Network Identity Manager has usability
issues due to the following causes:
- The "cursor row" is not always selected.
The "cursor row" is the row which the "cursor" is on. Navigating the
credentials view using the keyboard or clicking the credentials
display with the mouse will move the cursor to different rows.
However, this cursor row is not always selected, especially when
Network Identity Manager starts.
Having the selection be independent of the cursor row is a
requirement for supporting "toggle" selections (holding the 'ctrl'
key while clicking), which is a standard way of doing multiple
selections on Windows.
The problem with the cursor row not being selected when Network
Identity Manager starts is due to the delayed start of its plug-ins.
Even though the first row is initially selected, when plug-ins
complete initialization and notify the application about the
credentials that they see, those credentials end up accumulating
under different identities. The existing code didn't enforce the
selection state of the identity on the newly added
credentials. Since there were unselected credentials under the
selected outline level, the code would then turn off the selected
bit for the outline (which usually is an outline level for an
identity) for consistency.
The patch changes the behavior to enforce the selection state of the
enclosing outline on any new outline levels or credentials that are
added under it. This prevents an outline level from losing its
selection state when new credentials are added under it.
- Identities may have stale data associated with it.
The credentials view maintains a set of cached properties for each
identity that has credentials. During each refresh cycle, it would
go through the credentials and update the properties of each
identity. However it would not update the properties for identities
that are not associated with any credentials.
When the credentials associated an identity were deleted, the cached
properties for that identity sometimes never got reset. If the
identity was marked as "always visible", then it would be listed in
the credentials view along with the stale properties.
This patch properly initializes the properties of identities which
are not associated with any identities.
- Selection state is not updated when switching views.
The credentials view maintains selection state for individual
credentials when switching views. The same is not true for the
outlines since the outline needs to be reconstructed during the
switch.
The exising code failed to update the selection state of the
outlines after switching the view to reflect the the selection state
of the credentials. As a result, once a the user switched a view,
she might see outline levels which do not appear to be selected even
though all the credentials contained at the outline level appear
selected.
This patch properly adjusts the selection state of outline nodes to
correspond to the selection state of the contained credentials.
- Selection state may be inconsistent when more than one credential is
associated with a single row.
Some rows may represent more than one credential. A collapsed
outline represents all the credentials contained within that outline
level. In addition, two credentials that will appear the same to
the user (because all the displayed properties are the same) will be
represented by one row.
The selection state of these rows should be consistent with the
selection state of all the credentials that it represents. The
previous code did not enforce this constraint. This patch aims to
fix this by enumerating all the credentials that are represented
by each row and setting the selection state of each credential to
match the selection state of the row.

NIM: Handle WM_PAINT messages without update regions
It is possible to receive a WM_PAINT message in Windows without there
being an update region. For example, this can be caused by someone
calling RedrawWindow() with the RDW_INTERNALPAINT flag set. In this
case, GetUpdateRect() will indicate that there is no update region and
calling BeginPaint()/EndPaint() results in incorrect behavior.
The credentials window in Network Identity Manager needs to perform
special handling for this case by obtaining a proper device context
and completing the drawing operation.

NIM: do not permit resizing of filler columns
The credentials display of Network Identity Manager allows the user to
change the order and size of the displayed columns. However, some
columns are not resizable.
An oversight in the earlier code allowed the user to change the size
of "filler" columns. These columns are sized to fill up the remainder
of the display area after the other columns have been allocated.
Their width is determined by the size of the credentials display and
the width of the other columns. They are used in the basic view where
the only columns are the flags column (fixed width) and the identity
column (filler).
This patch prevents the "filler" columns (columns with the
KHUI_CW_COL_FILLER flag) from being resized.

NIM: Cannot cancel timers which have inserted a WM_TIMER message into the queue
The credentials view in Network Identity Manager displays several user
interface elements that need to be updated periodically such as any
fields that denote the time remaining for a credential or an identity,
or an icon and coloring used to indicate the expiration state. When
the display rows are computed, the credentials view creates a set of
timers that reference each row that times out when that row needs to
be redrawn.
Since the rows change when switching views or when the outline is
recomputed, all the timers are canceled and re-scheduled. However, a
race conditions exists where the timer times-out before it is
canceled, in which case a WM_TIMER message is placed in the
credential window's message queue. Windows does not support
canceling a timer that has already fired and has been placed on the
message queue.
By the time the WM_TIMER message is received by the window, the rows
of the display would have been recomputed and the row that the message
references may not be what it intended to reference. A spurious
WM_TIMER message is harmless when it refers to a row corresponding to
a credential. However, the existing code assumed that if a timer event
is received that referred to an outline row, then that outline must be
an expanded view of an identity, which is currently the only type of
outline row that receives timers. This assumption does not always
hold in the case of a spurious WM_TIMER message and may lead to the
code attempting to use the outline data as a handle to an identity.
The patch fixes the problem by checking if the row is actually an
expanded view of an identity and ignoring the message if it is not.

NIM: Context menu selection issues
The handler for WM_CONTEXTMENU in the credentials view of Network
Identity Manager assumed that the context menu was invoked using the
mouse. If it was, then the message parameters would specify the x and
y co-ordinates of the mouse. The context menu can also be invoked via
the keyboard, in which case the x- and y- coordinates are set to
(-1,-1).
An additional problem with the code is that it was not selecting the
row that was right-clicked on if it was not already selected. This
results in the some of the commands on the context menu targetting
credentials that the user didn't intend to target.
This patch adds support for handling the context menu when it is
invoked via the keyboard and also sets the selection to the row that
was right-clicked if the user invokes the context menu using the
mouse.

NIM: Color Schemas
The default color scheme used by the Network Identity Manager credentials
display can sometimes cause the text to be difficult to read. In
addition, since some of the colors are derived from colors used by the
current Windows theme, the selection, window background and text
colors may be mismatched with the colors that are hardcoded into the
application.
To rememdy this problem, this patch defines a new set of colors
that will be used with the credentials display. The new scheme
doesn't use a special color to distinguish the default identity which
is already indicated with the text "(Default)" displayed alongside it.
Instead the colors are used to denote the remaining lifetime of
credentials and identities.
Also, the color scheme defines all the colors that it uses instead of
deriving some of them from the Windows color scheme.
All the color information is now kept in the Network Identity Manager
UI schema. The schema automatically maps to the registry, so users
(and deployers) can override the colors by creating the necessary
registry keys and values. The registry keys containing color
information are:
Software\MIT\NetIDMgr\CredWindow\Themes and
Software\MIT\NetIDMgr\CredWindow\Themes\Default
The "Default" key contains the default color scheme. The color value
names are defined in ui\uiconfig.csv under Themes\_Schema
configuration subspace. Each color is represented by a 32-bit number.
The low-order 24 bits contain a COLORREF value. The high-order 8 bits
contain an alpha value which, if non-zero, will be used to blend the
color with the selection color (color value named ClrSelection).

NIM: Identity Configuration Panel Fixes
In the identity configuration panel of Network Identity Manager, the
user can specify a new identity which can then be configured.
The existing code didn't check if the identity specified by the user
already exists. The patch adds the check. If the identity already
exists, the user is notified as such.
Another bug prevented the user from configuring an identity that was
added back in following the deletion of the same identity during the
same session. The deleted status of the identity was not reset when
it was added back.
Additionally, this patch adds code that has already been added to the
new credentials dialog to apply Windows XP theme textures to the child
dialogs used as tab panels in the configuration dialog. Child dialogs
don't automatically adjust the theme settings based on whether it is
nested inside a tab control. The theme must be applied manually.

NIM: resource leak in khui_action_trigger()

Patch developed by kpkoch with style changes from jaltman
The size/position of the main application window is
internally updated in response to WM_MOVE messages but is
only written to the registry after a timeout period. This
is done due to the large number of WM_MOVE messages that
can be delivered during a windows drag / resize operation
involving the user or explorer shell's tile and cascade
operations. (or those involving third party desktop managers.)
In NIM 1.8 two different application view modes (standard
and advanced) replaced the single view mode in previous
releases. The size/position update logic was not modified
to take into consideration the possibility that a user might
move/resize the window and then quickly toggle modes before
the new location or size were recorded to the registry.
This change ensures that when a mode change occurs, via a
call to khm_set_main_window_mode(), that the current
location/size will be written to the registry and any
outstanding timer, MW_RESIZE_TIMER, will be cleared.
The logic to save the location/size has been extracted
into the new static function main_wnd_save_sizepos().
main_wnd_save_sizepos() is only called after the application
