Yes, you need it in order to link with the Hammurabi code [^]. Roll eyes | :rolleyes:

I don't think you can, without going the owner draw route, and doing lots of work.

But what can *can* easily do, is use a static control with the SS_NOTIFY style turned on, and handle the WM_COMMAND/STN_CLICKED that it send you.

Same clickability, less graphic goings-on.

Good luck,

Iain.

For Owner draw Chris Maunder has a good article about it(on the codeproject) and I suggest you see it but for buttons Custom Draw Buttons & A Smarter Groupbox[^] (A class to make working with radio buttons easier, and another for custom drawing buttons )

The __FUNCTION__ macro will give you the function name.

I suppose __FUNCTION__ would expand to "foo" while he's looking for "call" (i.e. the caller function name).

The easiest way is to require the calling function to pass in its name, which it can get with __FUNCTION__:

void fun(const char* callerName) 
{ 
  string str; 

  str = callerName;

  cout << str << endl; // I want output "call" 
} 

void call()
{
  fun(__FUNCTION__);
}

The answer you got before allowed you to set the gamma curve of the screen - by setting the OUTPUT brightness for an INPUT signal, you are specifying a function mapping input signal to output brightness - that'll be the contrast behaviour of the screen.

Anyway - what makes you think you can set the contrast of a monitor programmatically? The standard video interfaces include no mechanism for altering monitor brightness, contrast or colour temperature - indeed, in many older monitors, these controls were analogue, so would be very difficult, if not impossible to control from software at all. Where software controlled brightness and contrast are available (for example, in a laptop), the control of monitor characteristics is dependent on the monitor being used.

I want open the IE and link a web page.

Im code:

STARTUPINFO         si;
PROCESS_INFORMATION pi;
				
ZeroMemory(&amp;pi,sizeof(PROCESS_INFORMATION));
ZeroMemory(&amp;si,sizeof(STARTUPINFO));
si.cb          = sizeof(STARTUPINFO);  
			
LPCTSTR lpszPath = _T("C:\\Program Files\\Internet Explorer\\iexplore.exe");
LPCTSTR lpszCmdLine = _T("\"C:\\Program Files\\Internet Explorer\\iexplore.exe\"  \"http://www.google.com\"");
if( !CreateProcess( lpszPath , lpszCmdLine , NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS, NULL, NULL, &amp;si, &amp;pi) )
   return FALSE;

It is success !
But the return value is wrong !
"pi.dwProcessId" is wrong.(I wang enum the IE windows for the process ID, but fail!)
I enum all process by SPY++ tools, but not found the value("pi.dwProcessId")! Confused | :confused:

I don't quite understand the problem you are facing.
Is the IE window opening and navigating to the google page?

I use CreateProcess open IE window, and navigating to a page.

The action is success, and return some value in PROCESS_INFORMATION struce, include an process id of the IE window(dwProcessId).

Now,i want to close the IE window in code by the dwProcessId.

This is my method:

1) I enumerate all window and find the IE window by the dwProcessId.

EnumWindows(EnumProcessWndProc,(LPARAM)dwProcessId); 
BOOL CALLBACK EnumProcessWndProc(HWND hWnd,LPARAM lParam) 
{ 
	DWORD   dwProcessId; 
	GetWindowThreadProcessId(hWnd, dwProcessId); 
	DWORD dwProcess = (DWORD )lParam; 
	if(dwProcessId == dwProcess ) 
	{ 
           // this is IE window.
           // close the IE window.
           ::SendMessage(hWnd,   WM_CLOSE,   NULL,   NULL);
	   return FALSE; 
	} 
	return TRUE; 
}

The question is the return value(dwProcessId) frome CreateProcess is invadite of wrong!

Because not found the value(dwProcessId) by spy++ tools search all process.

I do not know is why !

Actually, on my system, the dwProcessId member of the PROCESS_INFORMATION struct is set correctly by the CreateProcess call (verified with Spy++).

As only as open the IE by the CreateProcess call, the dwProcessId member is not correctly, but open the other program is correctly!! Confused | :confused:
