3.7.4.2 AppDelete (Opnum 4)

  • Article

The AppDelete method deletes the application from the specified metabase path.

 HRESULT AppDelete(
   [in, unique, string] LPCWSTR szMDPath,
   [in] BOOL fRecursive
 );

szMDPath: A pointer to a Unicode string that contains the metabase path of the application.

fRecursive: A flag indicating whether application definitions are also to be deleted from all subkeys (TRUE) or just from the application at this key (FALSE).

Return Values:  A signed 32-bit value that indicates return status. If the method returns a negative value, it failed. If the 12-bit facility code (bits 16–27) is set to 0x007, the value contains a Win32 error code in the lower 16 bits. Zero or positive values indicate success, with the lower 16 bits in positive nonzero values containing warnings or flags defined in the method implementation. For more information about Win32 error codes and HRESULT values, see [MS-ERREF].

When processing this call, the server MUST do the following:

  • If the string length of the szMDPath parameter is <= 10, return E_INVALIDARG.

  • If the metabase path specified by szMDPath does not exist, return ERROR_PATH_NOT_FOUND.

  • If there is no application defined at the metabase path specified by szMDPath, return S_OK.

  • Delete the application. If fRecursive parameter is TRUE, delete applications at all child paths of szMDPath.

  • Remove the MD_APP_ISOLATED and MD_APP_ROOT properties from szMDPath. If fRecursive is TRUE, remove these properties from all child paths of szMDPath.
