OleUIBusy
Invokes the standard Busy dialog box, allowing the user to manage concurrency.
UINT OleUIBusy(
LPOLEUIBUSY lpBZ
| //Points to the initialization structure
| );
|
|
Parameter
lpBZ
Points 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 theOK button.
OLEUI_CANCEL
Indicates that user has pressed the Cancel button and that the caller should
cancel the operation.
OLEUI_BZ_SWITCHTOSELECTED
Indicates that 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_NOTREESPONDING flag is set.
OLEUI_BZ_RETRYSELECTED
Indicates that 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
Indicates that the dialog has been informed that the operation is no longer
blocked.
Standard Field Validation Errors
OLEUI_ERR_STANDARDMIN
Errors common to all dialogs 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 template.
OLEUI_ERR_LOADTEMPLATEFAILURE
Unable to load the dialog template.
OLEUI_ERR_DIALOGFAILURE
Dialog 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 dialogs 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.
Comments
The standard OLE Server Busy dialog box notifies the user that the server
application is not receiving messages. The dialog then asks the user to either
cancel the operation, switch to the task which is blocked, or continue waiting.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
