When I used MyDAC 5.20 I don't have any problem
with My dll, but After I Upgrade MyDAC to 5.50 it give problem with dll
The Code I Used:

Code: Select all

with qryCheques do begin
          Connection := dsDBConnection;
          SQL.Text := Format('select * from cheques where CMID in (%s)  order by CMNUM', [dsChequesNo]);
          Open;
end;

Did you recompile the DLL with MYDAC 5.5x?

Thank you for information. We have reproduced this problem and fixed it. This fix will be included in the next MyDAC build.
