Return value

Standard Success/Error Definitions

Return code	Description
OLEUI_FALSE	Unknown failure (unused).
OLEUI_OK	The user pressed the OK button.
OLEUI_SUCCESS	No error, same as OLEUI_OK.
OLEUI_CANCEL	The user pressed the Cancel button.

Standard Field Validation Errors

Return code	Description
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

Return code	Description
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 call LoadString for localized resources from the library.
OLEUI_ERR_OLEMEMALLOC	A call to the standard IMalloc allocator failed.

Function Specific Errors

Return code	Description
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_CSERR_LINKCNTRNULL	The lpOleUILinkContainer value is NULL.
OLEUI_CSERR_LINKCNTRINVALID	The lpOleUILinkContainer value is invalid.
OLEUI_CSERR_FROMNOTNULL	The lpszFrom value is not NULL.
OLEUI_CSERR_TONOTNULL	The lpszTo value is not NULL.
OLEUI_CSERR_SOURCEINVALID	The lpszDisplayName or nFileLength value is invalid, or cannot retrieve the link source.
OLEUI_CSERR_SOURCEPARSEERROR	The nFilename value is wrong.

Remarks

The link source is not changed by the Change Source dialog box itself. Instead, it is up to the caller to change the link source using the returned file and item strings. The Edit Links dialog box typically does this for the caller.

Note

The oledlg.h header defines OLEUICHANGESOURCE as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
