Is it possible to check the connection to MySQL-Database with MyConnection before MyConnection.connected := true. If there no connection to the database to show a message box (showmessage) but no error message.

Hello,
The only way to check if it's possibile to connect to a MySQL server is to perform a connection attempt. You can use the following code to avoid the error message:
Code: Select all
try
MyConnection.Open;
except
ShowMessage('Connection failed');
end;
Note that if you run your application from IDE, you will see the error message, but if you run the executable file, there will be only the 'Connection failed' message.
