            Title: How to send/get the priority of a process.
Question: Change the priority that Windows gives to your application or get what priority it has.
BE WARNED: YOUR APPLICATION CAN BLOCK THE OPERATING SYSTEM!!!
Answer:
Const
 ppIdle : Integer = -1;
 ppNormal : Integer = 0;
 ppHigh : Integer = 1;
 ppRealTime : Integer = 2;
Function SetProcessPriority( Priority : Integer ) : Integer;
Var
 H : THandle;
Begin
 Result := ppNormal;
 H := GetCurrentProcess();
 If ( Priority = ppIdle ) Then
 SetPriorityClass( H, IDLE_PRIORITY_CLASS )
 Else If ( Priority = ppNormal ) Then
 SetPriorityClass( H, NORMAL_PRIORITY_CLASS )
 Else If ( Priority = ppHigh ) Then
 SetPriorityClass( H, HIGH_PRIORITY_CLASS )
 Else If ( Priority = ppRealTime ) Then
 SetPriorityClass( H, REALTIME_PRIORITY_CLASS );
 Case GetPriorityClass( H ) Of
 IDLE_PRIORITY_CLASS : Result := ppIdle;
 NORMAL_PRIORITY_CLASS : Result := ppNormal;
 HIGH_PRIORITY_CLASS : Result := ppHigh;
 REALTIME_PRIORITY_CLASS : Result := ppRealTime;
 End;
End;
Function GetProcessPriority : Integer;
Var
 H : THandle;
Begin
 Result := ppNormal;
 H := GetCurrentProcess();
 Case GetPriorityClass( H ) Of
 IDLE_PRIORITY_CLASS : Result := ppIdle;
 NORMAL_PRIORITY_CLASS : Result := ppNormal;
 HIGH_PRIORITY_CLASS : Result := ppHigh;
 REALTIME_PRIORITY_CLASS : Result := ppRealTime;
 End;
End;
Use this:
 Function SetProcessPriority( Priority : Integer ) : Integer;
to set a priority to your application, or this:
 Function GetProcessPriority : Integer;
to get the actual priority.
