Dbexpress Error Invalid Handle

says i get an invalid handle on dbExpress. The error occurs in Delphi 7. These
Dbexpress Error Invalid Username Password
steps lead to the error: I put a SQLConnection, SQLTable, dbexpress invalid precision DataSetProvider, ClientDataSet, DataSource and DBGrid on my form. The SQLConnection point to a MySQL database dbexpress error 0x0015 on a remote server. SQLTable is linked to the SQLConnection with a table selected from the dropdown in the object inspector. Setting the SQLTable to active (design time) works fine. I link the other components to each other resulting in displaying the data from the table in the DBGrid. All of this works fine design time. But switching to runtime the application halts with the error: Exception EOleException in module Project1.exe at 000B6B2B. dbExpress error: Invalid handle. Searching for the address given leads nowhere, the line gives four questionmarks. How is it possible to establish a connection design time but not runtime? I also tested dbExpress with an Interbase database on a remote server, this works fine. In Delphi 8 i can not establish a connection to MySQL, not even design time. When i try to open the SQLTable (with setting the active property to true, design time) another error is shown: dbExpress error: [0x0003]: Invalid field type. Is there a solution for these problems?
