OLEUIBUSY
The OLEUIBUSY
structure contains information that the OLE User Interface Library uses to
initialize the Busy dialog box, and space for the library to return information
when the dialog box is dismissed.

Members
cbStruct
Size of the
structure in bytes. This field must be filled on input.
dwFlags
On input,
specifies the initialization and creation flags. On exit, it specifies the
user s choices. It may be a combination of the following flags:
BZ_DISABLECANCELBUTTON
Input only:
This flag disables the Cancel button.
BZ_DISABLESWITCHTOBUTTON
Input only:
This flag disables the Switch To... button.
BZ_DISABLERETRYBUTTON
Input only:
This flag disables the Retry button.
BZ_NOTRESPONDINGDIALOG
Input only:
This flag generates a Not Responding dialog box instead of a Busy dialog box.
The text is slightly different, and the Cancel button is disabled.
hWndOwner
Window that
owns the dialog box. It should not be NULL.
lpszCaption
Pointer to a
string to be used as the title of the dialog box. If NULL, then the library
uses Busy.
lpfnHook
Pointer to a
hook function that processes messages intended for the dialog box. The hook
function must return zero to pass a message that it didn t process back to the
dialog box procedure in the library. The hook function must return a non-zero
value to prevent the library s dialog box procedure from processing a message
it has already processed.
lCustData
Application-defined
data that the library passes to the hook function pointed to by the lpfnHook
member. The library passes a pointer to the OLEUIBUSY structure in the lParam
parameter of the WM_INITDIALOG message; this pointer can be used to retrieve
the lCustData member.
hInstance
Instance that
contains a dialog box template specified by the lpTemplateName member.
lpszTemplate
Pointer to a
null-terminated string that specifies the name of the resource file for the
dialog box template that is to be substituted for the library s Busy dialog box
template.
hResource
Customized
template handle.
hTask Input only:
Handle to the
task that is blocking.
lphWndDialog
Pointer to the
dialog box s HWND.
