the CatWalk example of thread control was written by Ron Thomas long times ago. it was a better example about thread control.
i translated it into x64 Uasm style. and added these "ExitThread,Ret "s function for a thread Exit.
pay attention to:
1. can't use ExitThread in your main thread, Use only own threads which will be exited.
2. monitoring the number of execution threads. 
3. relate to I/O, DLL, MEMORY. "RET" is best. "ExitThread" is better. "TerminateThread" isn't good on unless necessary

Find a little problem at rebuild.

      ;SendDlgItemMessageA PROTO hDlg:HWND ,nIDDlgItem:DWORD ,Msg:DWORD ,wParam:WPARAM ,lParam:LPARAM

WPARAM is a qword in X64 this made ThPriority1 (2) qword

hi: Biterider,Gunther,TouEnMasm
thank for your kind words and test.
especially,thank TouEnMasm for finding the error.

Code Select Expand

invoke SendDlgItemMessage, hdwnd, IDD_LB1, LB_GETCURSEL, 0,0
mov ThPriority1, rax
  invoke SendDlgItemMessage, hdwnd, IDD_LB2, LB_GETCURSEL, 0,0
mov ThPriority2, rax

mov rax,ThPriority1
sub eax, HOFFSET
  invoke SetThreadPriority, hThread1, eax

mov rax,ThPriority2
sub eax, HOFFSET
invoke SetThreadPriority, hThread2, eax
return TRUE


SetThreadPriority function (processthreadsapi.h)
Sets the priority value for the specified thread. This value, together with the priority class of the thread's process, determines the thread's base priority level.
Syntax
C++

BOOL SetThreadPriority(
  HANDLE hThread,
  int    nPriority
);

The SetThreadPriority parameters are a bit old.https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-setthreadpriority
I have changed those old parameters by the new in the upper link.
I have also added some various error messages.
bad parameters could be :

This value can be specified only if hThread is a handle to the current thread. The function fails

take care of that

hi,TouEnMasm
thank for you'd done on updating.
There are more functions of thread control:
1. update to 9 levels priority;
2. add to the errors checking;
;----------------------------------------------
the deeper impression is used to translate between the list index and the priority index.
