InternetConfirmZoneCrossingA function

-description

Checks for changes between secure and nonsecure URLs. Always inform the user when a change occurs in security between two URLs. Typically, an application should allow the user to acknowledge the change through interaction with a dialog box.

-parameters

-param hWnd [in]

Handle to the parent window for any required dialog box.

-param szUrlPrev [in]

Pointer to a null-terminated string that specifies the URL that was viewed before the current request was made.

-param szUrlNew [in]

Pointer to a null-terminated string that specifies the new URL that the user has requested to view.

-param bPost [in]

Not implemented.

-returns

Returns one of the following values.

Return code Description
ERROR_SUCCESS
 The user confirmed that it was okay to continue, or there was no user input required.
ERROR_CANCELLED
 The user canceled the request.
ERROR_NOT_ENOUGH_MEMORY
 There is not enough memory to carry out the request.

-remarks

Always inform the user when a change in security level occurs, or you risk subjecting the user to involuntary information disclosure.

Like all other aspects of the WinINet API, this function cannot be safely called from within DllMain or the constructors and destructors of global objects.

Note  WinINet does not support server implementations. In addition, it should not be used from a service. For server implementations or services use Microsoft Windows HTTP Services (WinHTTP).
 

Note

The wininet.h header defines InternetConfirmZoneCrossing 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. For more information, see Conventions for Function Prototypes.
