Parameters
- hdc
Type: System.UInt32
[in] Pointer to a long type to a hardware device context (HDC).
- cch
Type: System.Int32
[in] Number of characters, or -1 if null-terminated.
- pText
Type: array<System.UInt16[]
[in] OLE String that represents the text.
- pSize
Type: array<Microsoft.VisualStudio.OLE.Interop.SIZE[]
[in] Length of the OLE String.
Return Value
Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
