Назначение приоритета призапуске... 


Voldemar   (2001-09-25 04:12) [0]

Люди, подскажите, как бы мне назначить моей программе при запуске заданный приоритет? Чтобы вручную не менять каждый раз...
Заранее TNX!

Не уверен в ответе, но разве SetPriorityClass() не подойдет?



Mick Larini   (2001-09-26 02:52) [2]

Очень даже подойдет. Или SetThreadPriority() на Main VCL Thread.



Voldemar   (2001-09-26 02:58) [3]

Что-то я в хелпе ничего по этому поводу не нашел:((. Как оно работает и какой синтаксис, плз...

Плохо искал :)
С:\PROGRAM FILES\Common Files\Borland Shared\MSHelp\Win32.hlp
(если Delphi поставлена по умолчанию)
Или в Delphi набери имя функции и нажми на нем F1 :)


The SetPriorityClass function sets the priority class for the specified process. This value together with the priority value of each thread of the process determines each thread"s base priority level.

BOOL SetPriorityClass(

HANDLE hProcess, // handle to the process
DWORD dwPriorityClass // priority class value
);


Parameters

hProcess

Identifies the process.
Windows NT: The handle must have the PROCESS_SET_INFORMATION access right. For more information, see Process Objects.

dwPriorityClass

Specifies the priority class for the process. Specify one of the following values:
HIGH_PRIORITY_CLASS Specify this class for a process that performs time-critical tasks that must be executed immediately. The threads of the process preempt the threads of normal or idle priority class processes. An example is Windows Task List, which must respond quickly when called by the user, regardless of the load on the operating system. Use extreme care when using the high-priority class, because a high-priority class application can use nearly all available CPU time.
IDLE_PRIORITY_CLASS Specify this class for a process whose threads run only when the system is idle. The threads of the process are preempted by the threads of any process running in a higher priority class. An example is a screen saver. The idle-priority class is inherited by child processes.
NORMAL_PRIORITY_CLASS Specify this class for a process with no special scheduling needs.
REALTIME_PRIORITY_CLASS Specify this class for a process that has the highest possible priority. The threads of the process preempt the threads of all other processes, including operating system processes performing important tasks. For example, a real-time process that executes for more than a very brief interval can cause disk caches not to flush or cause the mouse to be unresponsive.


Return Values

If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Every thread has a base priority level determined by the thread"s priority value and the priority class of its process. The system uses the base priority level of all executable threads to determine which thread gets the next slice of CPU time. The SetThreadPriority function enables setting the base priority level of a thread relative to the priority class of its process. For more information, see Scheduling Priorities.
