I get a "Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another" exception...2003-09-03 05:54:56 PM delphi201 Does anybody know what's this about? Let me explain the situation. The application is a server listening for connections from about 60 clients (so, 60 threads waiting for data). This clients send through a socket commands that produce inserts to the database located at the server. These inserts are always the same, the only variation is the parameters, so I have a DataModule with 3 parametrized queries (there are three kinds of inserts). When a thread receives a command, it locks the query using a TCriticalSection, sets the parameters and sends this query to another thread, which has a queue of pending queries to execute. This thread makes a clone of the query and encues it. After that, the first thread releases the CriticalSection. This usually goes fine, but, after a while (depending on the frequency that the clients send commands) it produces an exception with the text: "Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another". It only does it once, after this exception the application runs fine... strangely, I put all the sentences in a try except block and the except sentences aren't executed... I have tried with a breakpoint and also a showmessage, but it seems that it doesn't execute them... After receiving the exception, I have introduced the insert sentence by myself at the SqlServer query analizer, and it worked ok, so I don't have any idea of what's this all about... Any idea?? Thanks! Arnau. |
