# OleUIBusy

Invokes the standard Busy dialog box, allowing the user to manage concurrency.

UINT OleUIBusy(

LPOLEUIBUSY lpBZ | //Pointer to the initialization structure
); |

Parameter

lpBZ
  [in] Pointer to an OLEUIBUSY structure that contains information used to initialize the dialog box.

Return Values

Standard Success/Error Definitions

OLEUI_FALSE
  Unknown failure (unused).
OLEUI_SUCCESS
  No error, same as OLEUI_OK.
OLEUI_OK
  The user pressed the OK button.
OLEUI_CANCEL
  The user has pressed the Cancel button and that the caller should cancel the operation.
OLEUI_BZ_SWITCHTOSELECTED
  The user has pressed Switch To and OleUIBusy was unable to determine how to switch to the blocking application. In this case, the caller should either take measures to attempt to resolve the conflict itself, if possible, or retry the operation. OleUIBusy will only return OLEUI_BZ_SWITCHTOSELECTED if the user has pressed the Switch To button, hTask is NULL and the BZ_NOTRESPONDING flag is set.
OLEUI_BZ_RETRYSELECTED
  The user has either pressed the Retry button or attempted to resolve the conflict (probably by switching to the blocking application). In this case, the caller should retry the operation.
OLEUI_BZ_CALLUNBLOCKED
  The dialog box has been informed that the operation is no longer blocked.

Standard Field Validation Errors

OLEUI_ERR_STANDARDMIN
  Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_ERR_STRUCTURENULL
  The pointer to an OLEUIXXX structure passed into the function was NULL.
OLEUI_ERR_STRUCTUREINVALID
  Insufficient permissions for read or write access to an OLEUIXXX structure.
OLEUI_ERR_CBSTRUCTINCORRECT
  The cbstruct value is incorrect.
OLEUI_ERR_HWNDOWNERINVALID
  The hWndOwner value is invalid.
OLEUI_ERR_LPSZCAPTIONINVALID
  The lpszCaption value is invalid.
OLEUI_ERR_LPFNHOOKINVALID
  The lpfnHook value is invalid.
OLEUI_ERR_HINSTANCEINVALID
  The hInstance value is invalid.
OLEUI_ERR_LPSZTEMPLATEINVALID
  The lpszTemplate value is invalid.
OLEUI_ERR_HRESOURCEINVALID
  The hResource value is invalid.

Initialization Errors

OLEUI_ERR_FINDTEMPLATEFAILURE
  Unable to find the dialog box template.
OLEUI_ERR_LOADTEMPLATEFAILURE
  Unable to load the dialog box template.
OLEUI_ERR_DIALOGFAILURE
  Dialog box initialization failed.
OLEUI_ERR_LOCALMEMALLOC
  A call to LocalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_GLOBALMEMALLOC
  A call to GlobalAlloc or the standard IMalloc allocator failed.
OLEUI_ERR_LOADSTRING
  Unable to LoadString localized resources from the library.
OLEUI_ERR_OLEMEMALLOC
  A call to the standard IMalloc allocator failed.

Function Specific Errors

OLEUI_ERR_STANDARDMAX
  Errors common to all dialog boxes lie in the range OLEUI_ERR_STANDARDMIN to OLEUI_ERR_STANDARDMAX. This value allows the application to test for standard messages in order to display error messages to the user.
OLEUI_BZERR_HTASKINVALID
  The hTask specified in the hTask member of the OLEUIBUSY structure is invalid.

Remarks

The standard OLE Server Busy dialog box notifies the user that the server application is not receiving messages. The dialog box then asks the user to cancel the operation, switch to the task that is blocked, or continue waiting.
