In apartment model threading, multiple clients can make simultaneous calls to the same DLL and all be processed at the same time.

Each client can only make one call at a time and will wait for the MTDLL to complete its processing before proceeding.

>Do you mean "In apartment model threads run in a queue. Must finished first before begin second."?. If you said that it enough for me. My only need VFP don't wait for thread.
>Do you send me a sample? I think there is a sample in VFP but nothing. A guy sent me before months ago but I lost that.
