putrcolumndata with pointer

[georget]

We use Delphi V and assoc mydac-
We have a variable normally accessible as a pointer which is initialized with a getmem(ptr,size) line of code. We modify the pointer referenced contents and now want to store the referenced contents in a text column in on-line data base. can I use the putcolumndata method with the ptr as datasource like
putcolumndata(fieldname,1,ptr)
or if not, can I typecast pointer as Pchar and use

putcolumndata(fieldname,1,Pchar(ptr))?Thanks,

Jennifer good

Try:

1: Convert the data to a string
2: Use TMyquery to store it:

with MyQuery do begin
Append; // or Edit if its an update.
FieldByName('theField').asstring := TheNewString;
Post;
end

You can use the following code:

Code: Select all

PutColumnData(fieldname, 1, string(PChar(ptr)));
