I am trying to create threads as needed to send queries out and wait ( in a
thread) for the response.
I am getting the following errors:

//--------------------------------------------------------------------------
-
void __fastcall TForm1::Button1Click(TObject *Sender)
{
 HANDLE TempthreadHandle = NULL ;
 DWORD Tempthreadid = 0 /*, Param = 0 */;
 //LPVOID lpVoid = &Param ;

 TempthreadHandle = CreateThread(NULL, 0, ThreadProc, NULL, 0,
&Tempthreadid) ; // LPTestUnit1.cpp(77)

  ...

//--------------------------------------------------------------------------
-
LPTHREAD_START_ROUTINE TForm1::ThreadProc(LPVOID){

 ...


//--------------------------------------------------------------------------
-

 Compile errors:

[C++ Error] LPTestUnit1.cpp(77):
 E2034 Cannot convert 'unsigned long (__stdcall * (* (_closure )(void
*))(void *))(void *)'
                   to 'unsigned long (__stdcall * )(void *)'


[C++ Error] LPTestUnit1.cpp(77):
E2342 Type mismatch in parameter 'lpStartAddress'
 (
   wanted 'unsigned long (__stdcall *)(void *)',
      got 'void'
 )
