NAME: I_SystemFocusDialog
|
||
|
|
|
||
|
|
SYNOPSIS: Popup a dialog box and get the domain or server name
|
||
|
|
|
||
|
|
ENTRY: hwndOwner - owner window handle
|
||
|
|
nSelectionType - Determines what items the user can select
|
||
|
|
pszName - the string buffer which contains the
|
||
|
|
return value. It can be either domain name or server
|
||
|
|
name. ( server name will start with "\\" )
|
||
|
|
cchBuffSize - the max buf size of pszName
|
||
|
|
pfOK - TRUE if user hits OK button. FALSE if user
|
||
|
|
hits a CANCEL button.
|
||
|
|
|
||
|
|
EXIT: LPWSTR pszName - if user hits okay button, it will
|
||
|
|
return either a domain name or a server name. (
|
||
|
|
server name always starts with "\\" ). It will be
|
||
|
|
undefined if the user hits Cancel button.
|
||
|
|
BOOL *pfOK - TRUE if user hits ok button. FALSE
|
||
|
|
otherwise.
|
||
|
|
|
||
|
|
RETURNS: UINT - (APIERR) - NERR_Success if the operation is succeed.
|
||
|
|
NERR_BufTooSmall, the string buffer is too
|
||
|
|
small. It will not set the string if the
|
||
|
|
buffer is too small.
|
||
|
|
|
||
|
|
NOTES: The reason the return type is UINT and not APIERR is because
|
||
|
|
APIERR is not a public definition, and this API is exported
|
||
|
|
for public use.
