Re^2: calling a function from a dll

$value =~ s!\0.*!!; # we assume that the first \0 returned indicates end of the string

That is a pretty bad assumption. BSTRs are fixed length arrays of unsigned shorts with a prefix length and can contain multiple nulls.

what is interesting is that the prefix length is a byte count and not a character count,although BSTR is always Unicode So to find the end of the string you have to get to the stored length which is stored in the first 2 bytes the example at : BSTR layout shows the byte count and the terminated nulls,both required by BSTR	[reply]
