Problem in pinpointing an error

[brace]

hello.

My application sudden (=after a new release) started to give problems only on some machines. I cannot reproduce it on my developement machine.

It is probably an Exception fired somewhere in the SDAC code. The error users get is

Valori dei parametri di input non validi. Controllare i valori di stato per ulteriori dettagli.

By googling i foudn it is related to this:
http://support.microsoft.com/kb/949959

I tried with MadExcept but it seems not working with components code, so I would like to ask you what can cause this.
I am using 6.1.6 for RadStudio XE2.

THanks

I found the problem. I solved by initializing a MSQUeery parameter on the BeforeOpen event.

Now my question is:
why the invalid parameters error occurs only on some machines?

Please try creating a small sample that demonstrates the problem and send it to andreyz*devart.com , including a script to create all needed server objects (tables, stored procedures, etc.). Also please specify the exact version of SQL Server server and client you are using. You can learn it from the Info sheet of TMSConnection Editor.
