Hi DavidCrow,

What product are you talking about when you say profiler? VC6 or something else?

George

The profiler that comes with VS. It's on the Build menu.

Hi DavidCrow,

I have found that in the build menu of Visual Studio 2003, there is nothing called profier. Which IDE are you using?

George

How get net screen size?

I've got an application which I want to fit into the y dimension of the screen. The function:
cyMon = ::GetSystemMetrics( SM_CYSCREEN);
gives me the screen dimension, but I want the net dimension not including the task bar, if the task bar isn't being auto-hidden.
I see that if I hit the maximize button, the system is clever enough to take into consideration whether or not the task bar is displayed.
If I could somehow get the system to tell me what its maximize size it, that would give me the answer. The GetSystemMetrics gives me the same answer, with and without the task bar.
Does anyone know the appropriate call?

Thanks,
Ilan

You need to use SystemParametersInfo with the SPI_GETWORKAREA value: Retrieves the size of the work area on the primary display monitor. The work area is the portion of the screen not obscured by the system taskbar or by application desktop toolbars. The pvParam parameter must point to a RECT structure that receives the coordinates of the work area, expressed in virtual screen coordinates.

i use the code to mininmize all open windows
::PostMessage(FindWindow("Shell_TrayWnd",NULL)->GetSafeHwnd(),WM_COMMAND,MAKELONG(415,0),0);
::PostMessage(FindWindow("Shell_TrayWnd",NULL)->GetSafeHwnd(),WM_COMMAND,MAKELONG(416,0),0);
but the dialog box on which button to minimize all does not minmimize.
that is all open windows minimize except the dialog box containing button
.and i do coding on this button
thanks

why not call ShowWindow(SW_MINIMIZE)after your ::PostMessage commands?

You can accomplish this in three calls then...the PostMessage commands you have (will minimize all windows except the dialog calling it).

Then use ShowWindow(SW_MINIMIZE) to minimize the current window.

but it does not minimize all windows it minimize only itself and one window.
and also tell me if button is on third dialog then last two dialog are not minimized

Doesn't this mean that the only window not minimized is the one with the "button" on it? At this point in your program, you only have 1 window left open? If so, call the ShowWindow now and this one window will minimize.

Why not something as simple as:

keybd_event(VK_LWIN, 0, 0, 0);
keybd_event(77, 0, 0, 0);
keybd_event(VK_LWIN, 0, KEYEVENTF_KEYUP, 0);

That's a terrible technique. You need to check if applications have a systembox and, if so, if the minimize button is visible. Otherwise you are risking sending an application a message it specifically chooses not to handle, often triggering unexpected states in the code.

i have the folowing function that doesn't work:
i get an error like: "MultiByteToWideChar' : cannot convert parameter 5 from 'char *' to 'unsigned short *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast"

I think you need to use WCHAR instead of LPTSTR and for sizeof(TCHAR) use sizeof(WCHAR)
hope this helps

Shouldn't that be:
LPWSTR lpszBuffer = reinterpret_cast<LPWSTR>(_alloca(dwBytesRead+1)*sizeof(WCHAR));

Personally, I wouldn't use _alloca, I'd use something like

WCHAR wszBuffer[102]; // If you really must use magic numbers...

Hello,

replace your code:

<br />
 // Convert the ANSI data to Unicode<br />
LPTSTR lpszBuffer = LPTSTR(_alloca((dwBytesRead+1)*sizeof(TCHAR)));<br />

with this code:

<br />
// i use similar like this:<br />
TCHAR* unicode_string;<br />
unicode_string = (TCHAR*)calloc(dwBytesRead+1, sizeof(TCHAR));<br />

maybe helps?

or try instead LPTSTR to use LPWSTR???
regards

maybe u haven't define _UNICODE. Hence
LPTSTR lpszBuffer is equavalent to char* lpszBuffer.

so

Either define _UNICODE
or
change LPTSTR lpszBuffer to wchar_t* lpszBuffer;
