Functions

DosDateTimeToVariantTime(int wDosDate, int wDosTime, Pointer<Double> pvtime) → int

Converts the MS-DOS representation of time to the date and time representation stored in a variant.

GetActiveObject(Pointer<GUID> rclsid, Pointer<NativeType> pvReserved, Pointer<Pointer<COMObject>> ppunk) → int

Retrieves a pointer to a running object that has been registered with OLE.

SysAllocString(Pointer<Utf16> psz) → Pointer<Utf16>

Allocates a new string and copies the passed string into it.

SysAllocStringByteLen(Pointer<Utf8> psz, int len) → Pointer<Utf16>

Takes an ANSI string as input, and returns a BSTR that contains an ANSI string. Does not perform any ANSI-to-Unicode translation.

SysAllocStringLen(Pointer<Utf16> strIn, int ui) → Pointer<Utf16>

Allocates a new string, copies the specified number of characters from the passed string, and appends a null-terminating character.

SysFreeString(Pointer<Utf16> bstrString) → void

Deallocates a string allocated previously by SysAllocString, SysAllocStringByteLen, SysReAllocString, SysAllocStringLen, or SysReAllocStringLen.

SysReAllocString(Pointer<Pointer<Utf16>> pbstr, Pointer<Utf16> psz) → int

Reallocates a previously allocated string to be the size of a second string and copies the second string into the reallocated memory.

SysReAllocStringLen(Pointer<Pointer<Utf16>> pbstr, Pointer<Utf16> psz, int len) → int

Creates a new BSTR containing a specified number of characters from an old BSTR, and frees the old BSTR.

SysReleaseString(Pointer<Utf16> bstrString) → void

Decreases the pinning reference count for the specified string by one. When that count reaches 0, the memory for that string is no longer prevented from being freed.

SysStringByteLen(Pointer<Utf16> bstr) → int

Returns the length (in bytes) of a BSTR.

SysStringLen(Pointer<Utf16> pbstr) → int

Returns the length of a BSTR.

VarBstrCat(Pointer<Utf16> bstrLeft, Pointer<Utf16> bstrRight, Pointer<Pointer<Uint16>> pbstrResult) → int

Converts a variant from one type to another.

VarBstrCmp(Pointer<Utf16> bstrLeft, Pointer<Utf16> bstrRight, int lcid, int dwFlags) → int

Compares two variants of type BSTR.

VariantChangeType(Pointer<VARIANT> pvargDest, Pointer<VARIANT> pvarSrc, int wFlags, int vt) → int

Converts a variant from one type to another.

VariantClear(Pointer<VARIANT> pvarg) → int

Clears a variant.

VariantCopy(Pointer<VARIANT> pvargDest, Pointer<VARIANT> pvargSrc) → int

Frees the destination variant and makes a copy of the source variant.

VariantInit(Pointer<VARIANT> pvarg) → void

Initializes a variant.

VariantTimeToDosDateTime(double vtime, Pointer<Uint16> pwDosDate, Pointer<Uint16> pwDosTime) → int

Converts the variant representation of a date and time to MS-DOS date and time values.

VariantTimeToSystemTime(double vtime, Pointer<SYSTEMTIME> lpSystemTime) → int

Converts the variant representation of time to system time values.
