// History: ??-???-?? KrishnaG created
|
||
|
|
// 07-Sep-97 t-blakej Commented, cleaned up, made
|

|
// Since this class is useful outside of ADSI, some work has been taken to
|
||
|
|
// make it not depend on any ADSI-specific code. It needs two ADSI header
|
||
|
|
// files (cdispmgr.hxx and iprops.hxx), but they only depend on definitions
|
||
|
|
// from standard system header files.
|
||
|
|
//
|
||
|
|
// To accomodate the current building method in ADSI, the precompiled
|
||
|
|
// header "procs.hxx" is included; this includes all the necessary ADSI
|
||
|
|
// header files and definitions. But for use outside of ADSI, the few
|
||
|
|
// necessary header files are explicitly included below; see the comment by
|
||
|
|
// "#ifndef ADsAssert".
|
||
|
|
//
|
||
|
|
// So if not compiling for ADSI, comment the following two lines out.
|
||
|
|
//
