Function Specific Errors

Return code Description

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 that 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 is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
