This topic describes Vista specific features of LMD VCL shared runtime.

== Vista detection ==
LMD SysIn unit provides several system information services. To detect whether current operating system is Windows Vista:

* Check LMDSIWindowsVista variable whether current operating system is exactly Windows Vista.
* Check LMDSIWindowsVistaUp variable whether current operating system is Windows Vista or better.

== Aero Glass detection ==
To check whether Aero Glass is currently enabled and active, use functions and variables of LMDDwmAPI unit.
The global LMDDwmEnabled variable reports whether Aero Glass is enabled. In addition the state of each window can be tested and modified:

<delphi>function LMDWndIsDwmEnabled(Handle:THandle):Boolean;</delphi>
Returns true when Dwm is enabled for a specific window (specified by Handle parameter).

<delphi>function LMDWndDwmDisable(Handle:THandle):Boolean;</delphi>
Disables Aero Glass feature for the window specified by Handle parameter.

<delphi>function LMDWndDwmEnable(Handle:THandle):Boolean;</delphi>
Enables Aero Glass feature for a window specified by Handle parameter. Certainly only applicable, when LMDDwmEnabled returns true.

== Vista Dialogs ==

Open/SaveDialog

 === UseLatestCommonDialogs Variable ===
 To support latest new Vista FileOpen/FileSave dialogs you can use the new TFileOpenDialog/TFileSaveDialog controls in the VCL. The major drawback for these control is, that they will not work in environments before Windows Vista. To make sure that your app works on all Windows systems (using the latest possible dialogs), you should use following approaches:
-* Set the global variable UseLatestCommonDialogs to true somewhere in your code. Now Open/Save dialogs use latest available common dialogs (but you can not use advanced features TFileOpenDialog/TFileSaveDialog provide).
+* Set the global variable UseLatestCommonDialogs to true somewhere in your code (default setting). Now Open/Save dialogs use latest available common dialogs (but you can not use advanced features TFileOpenDialog/TFileSaveDialog provide).
 * Use the TLMDFileOpenDialog/TLMDFileSaveDialog controls. They offer flexibility of TFileOpenDialog/TFileSaveDialog components, but you can assign standard TOpenDialog/TSaveDialog references with their corresponding settings for non-Vista environments.

-Similar feature is available for the new TLMDTaskDialog component. On Windows Vista the system taskdialog is used, on all other environments the features of the TaskDialog are emulated (so the features of this nice extended message dialog can be used on non-Vista systems as well).
