Question: I want to send text stored as a TText8* array to the DrawText() method of a bitmapped graphics context. But I need to convert
it first to a TDesC16. What's the recommended way to do this?
Answer: A TPtr8 constructor will do a conversion from TText8* and the Copy() method of TDesC16 will do the conversion to 16-bit, as follows:
TText8[] myData=...; const TInt length = sizeof(myData); // length of the array TPtr8 ptr(myData, length, length); TBuf16 buf16; buf16.Copy(ptr);
There is incidentally a corresponding Copy() method of TDesC8 which will do the reverse conversion from 16-bit to 8-bit, provided the data values do not exceed 255 (decimal).
