The MsiCloseHandle function closes an open installation handle.


UINT MsiCloseHandle(
  [in] MSIHANDLE hAny


[in] hAny

Specifies any open installation handle.

Return value

Value Meaning
An invalid handle was passed to the function.
The function succeeded.


MsiCloseHandle must be called from the same thread that requested the creation of the handle.

The following functions supply handles that should be closed after use by calling MsiCloseHandle:

MsiCreateRecord MsiGetActiveDatabase MsiGetLastErrorRecord MsiOpenPackage MsiOpenProduct MsiOpenDatabase MsiDatabaseOpenView MsiViewFetch MsiViewGetColumnInfo MsiDatabaseGetPrimaryKeys MsiGetSummaryInformation MsiEnableUIPreview Note that when writing custom actions, it is recommended to use variables of type PMSIHANDLE because the installer closes PMSIHANDLE objects as they go out of scope, whereas you must close MSIHANDLE objects by calling MsiCloseHandle.

For example, if you use code like this:

MSIHANDLE hRec = MsiCreateRecord(3);

Change it to:

PMSIHANDLE hRec = MsiCreateRecord(3);
