POffsetInfoType_String (UnspecifiedOffsetinfo1 and UnspecifiedOffsetinfo1)

[aarmando73]

Hello Thomas,
I see UnspecifiedOffsetinfo1 and UnspecifiedOffsetinfo1 in POffsetInfoType_String are the max size of the string (one is 2 bigger because consider the parameters MaxLength (i.e. 256) and UsedLength (i.e 254)).

It is curious that sometimes the UnspecifiedOffsetinfo1=254 and UnspecifiedOffsetinfo2=256 and sometime UnspecifiedOffsetinfo1=256 and UnspecifiedOffsetinfo2=254.
If you read the single item obviously this is not a problem.

In my test with plain string variables (no array) it was always as expected.

I see a difference when there's a Array of WString. Then I get at Offsetinfo1 = 254 (correct) but Offsetinfo2 = 512. But a plain WString in the same datablock gives Offsetinfo1 = 254 and Offsetinfo2 = 256. But this difference comes from padding bytes, which are added in a WString-Array (can be seen in a not-optimized DB).

At least for writing strings the values should be correct, because you need to write the complete length with the string-header.
