There is a heap on the interface of parameters need to read in the thread, do how? The global variable? Critical section? Not to go crazy,,,

CodePudding user response:

Thread is unfavorable to the VCL, speaking, reading and writing data, global variables usually only, speaking, reading and writing.

CodePudding user response:

This kind of situation, simple recommend the use of static members, complex with synchronization, do not have direct access to the UI elements
