---- In case your application requires a fairly long time for a whole lot of information processing, this period of time lengthy enough to ensure that Windows doesn't detect consumer actions through the activation of the display saver, as soon as the screen saver starts , your plan is actually slower, and this may significantly impact the regular operation of the plan. Is there a approach to make the information processing program for any long time before making off the display screen safety? The answer is indeed. Windows just before beginning the screen saver will activate the software to send the existing WM_SYSCOMMAND concept, which wParam parameter specifies the type of system instructions to be executed, in this situation, the worth SC_SCREENSAVE. The issue is methods to seize the news program it? In C + + Builder might be used Tapplication OnMessage occasion handler class to handle the news. Any software received immediately after the Windows message will set off Tapplication OnMessage class activities, by defining the occasion handler, it is possible to deliver for the software captures all Windows messages (naturally not incorporated inside the plan together with the SendMessage perform to deliver the concept) .
---- OnMessage events are outlined as follows:

typedef void__fastcall (__closure
* TMessageEvent) (tagMSG & Msg, bool & Handled);
__property TMessageEvent OnMessage =
read = FOnMessage,Office 2007 Product Key, write = FOnMessage;


---- OnMessage which TMessageEvent sort is the type of event that defines the process of processing a message, Msg parameters are given facts about Windows messages Its structure is as follows:

typedef struct tagMSG
HWND hwnd;
UINT message;
WPARAM wParam;
LPARAM lParam;
DWORD time;
POINT pt ;


---- Handled parameter determines how the message for further processing, if a message is acquired soon after the Handled parameter is set to true, then the concept will not be further treatment, during this situation is to remove the display saver activated.

---- Start C + + Builder, create a project file, the header files to increase in the Private section with the member function CaptureMessage statement:

class TForm1: public Tform

__published:
private:
void __fastcall CaptureMessage (tagMSG & Msg, bool & Handled);
public:
__fastcall TForm1 (Tcomponent * Owner);
;


---- in. cpp file to add CaptureMessage definition:

void __fastcall TForm1:: CaptureMessage (tagMSG & Msg, bool & Handled)

if (Msg.message = = WM_SYSCOMMAND & & Msg.wParam = = SC_SCREENSAVE)
Handled = true; / / stop the screen saver starts
else
Handled = false; / / to the message The default processing



---- then function as outlined CaptureMessage OnMessage an occasion processor, the main form add the subsequent code in the OnCreate event handler :

void __fastcall TForm1:: FormCreate (Tobject * Sender)

Application-> OnMessage = CaptureMessage;



---- Press F9 to compile and run the plan, it is possible to advance the screen saver wait time set to a worth as small as attainable to test the operation from the plan. You will find within the plan is running, the display screen saver will not be activated, close running programs and then wait to get a while, the display screen saver would normally appear. The above code in C + + Builder3, win98 environment to run through the
