Hi, We have just noticed a strange behaviour recently, which I couldn't figure out how to resolve. The issue could have been there all the time, just we didn't used the sequence before. We have an application, uses ADO to connect to SQL Server database. Components used include TADOQuery, TADOStoreProcedure etc. It all works fine. Then we have a form which contains among other things, a TWebBrowser and a 'Print' button. On click event of the Print button, we call: WebBrowser_Help.ExecWB(OLECMDID_PRINT, 1);
Which will bring up printing dialog and print the contents of the TWebBrowser component. The strange thing is that after the Print button clicked, subsequent access to database via ADO components all failed with Exception. The following is a sample exception message: Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another I have tried to close ADOConnection, reopen etc, the database access still doesn't success. Anyone knows how to fix this issue? Edward
