Returns the subnode value as a Boolean value (performing acceptable type conversion if necessary).
Syntax
HRESULT GetBool([in] LPWSTR sKey,
[in, defaultvalue(0)] VARIANT_BOOL bDefVal,
[out, retval] VARIANT_BOOL* bVal);
Parameters
- sKey
- [in] Value of LPWSTR.
- Identifies a subnode. See CAB subnode identification syntax.
- bDefVal
- [in, defaultvalue(0)] Value of VARIANT_BOOL.
- A value to be returned in case of error (subnode does not exist, has incompatible type etc.).
- bVal
- [out, retval] Pointer to VARIANT_BOOL.
- The address of a
VARIANT_BOOLvariable that receives a referenced subnode value.
Return Value
Returns S_OK if operation was successful or error code in other cases.
