VCL is not thread safe. Therefore I guess it is not a good idea to write information to the gui in the INDY 10 TCP server.execute(...) function .
How to send information from the server execute to the VCL ?
I need to modify a TBitmap inside a tcpserver.execute function. How to make that thread safe ?
Write stuff to the VCL thread from Indy the same way to write stuff to the VCL thread from anywhere else. Common options include
TThread.SynchronizeandTThread.Queue.Modifying a standalone
TBitmapshould not require synchronization with the main thread. You can modify it from any thread you want, as long as you do it from only one thread at a time. You can use the standard synchronization objects like critical sections and events to make sure only one thread uses it at a time.
