c++ - Button control takes some time to disable in dialog box -

-

I'm trying to take some long action in the dialog box from my mainthread. During that time I wanted to disable some control. I used EnableWindow (FALSE) for each control to disable it. But all other control except button control (such as slider control, CMFCIDitbro control, combo box control) are fully disabled before processing. But buttons are taking more time to disable control, they are almost finished when the operation is finished. As soon as I call EnableWindow (FALSE), were not disabling button controls? Why is it taking time to disable it?

You need to completely perform background tasks in another thread, and UI / control can be used by another thread You should use PostMessage , if the call does not work directly on EnableWindow Setfocus , for example, does not work with a different thread

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
