Is there a way to monitor if the USB port on system has had its connector removed?

I'm trying to draw a bitmap with a highlighted effect with the following code:
HBRUSH hSelBrush = CreateSolidBrush(GetSysColor(COLOR_HIGHLIGHT));
DrawState(hDC, hSelBrush, NULL, MAKELPARAM(hBmp, 0), 0, x, y, ImgWidth, ImgHeight, DST_BITMAP | DSS_UNION);
DeleteObject(hSelBrush);
The problem is that it doesn't do it on the white pixels. Is there any way to fix it?
-thanks

Hi!
I would like to change the cursor of the entire system temporarily, so I cannot use SetSystemCursor. My goal is to hide the cursor, so I can either hide it or change it to a blank one that I load. ShowCursor(FALSE) seems to only apply to the current window.
Any help would be appreciated.

That's because the cursor is a shared resource. In Win32 one app isn't allowed to control such a resource since it would affect all apps running on the system.

You can change system wide cursor using ::SetSystemCursor() API. Then what else the problem u have. Just create a blank cursor in ur resource editor( here IDC_CURSOR1) Load it... Create another one cursor which is having ur system cursor ( here IDC_CURSOR2).
void CTestDlg::OnHideCursor()
{
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR1 ) ;// User your blank cursor here
HCURSOR h2 = CopyCursor ( h1 ) ;
::SetSystemCursor ( h2, OCR_NORMAL ) ;
}
void CTestDlg::OnShowCursor()
{
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR2 ) ;// User your system cursor here
HCURSOR h2 = CopyCursor ( h1 ) ;
::SetSystemCursor ( h2, OCR_NORMAL ) ;
}
Thatzaal..;)

Thanks
The hide cursor code works great, but when I show the cursor again, I want it to be the user's cursor, not one stored in my resources. So instead of AfxGetApp()->LoadCursor(...) for the show function, I'm trying this:
HCURSOR h1=LoadCursor(0,IDC_ARROW);<br />
HCURSOR h2=CopyCursor(h1); <br />
::SetSystemCursor(h2,OCR_NORMAL);
Which doesn't work, and I have to restore the cursor otherwise. How can I restore the original cursor?

Ya.. I dOno why its not working... but there is another one solution to restore the system cursor (without using ur resource). Declare a HCURSOR m_h; member variable to ur dlg class.
void CTestDlg::OnHideCursor()
{
m_h=CopyCursor(LoadCursor(NULL,IDC_ARROW)); // Store system cursor in m_h
HCURSOR h1 = AfxGetApp( ) -> LoadCursor ( IDC_CURSOR1 ) ; // Load ur cursor
::SetSystemCursor ( h1, OCR_NORMAL ) ; // Change system cursor with urs
}
void CTestDlg::OnShowCursor()
{
::SetSystemCursor ( m_h, OCR_NORMAL ) ; // Restore system cursor from m_h
}
It is working well for me. Try urself.
Hava nice day;)
with regards

That works wonderfully! Thank you very much! I tried doing something similar but mine involved copy cursor and it didn't work right, so simple and elegent.

I am writing a web download installer and need to make it as small as possible. A lot of MFC is a black box to me so I am not sure which pieces I can hack out and still expect the program to behave as expected.
It is currently 210 KB and I only wrote a thousand or so lines of source code (including comments). There is only 1 window and it is a dialog-based app. It does use the file open common dialog box and afxinet.h
Thanks!

lets see... you could use an executable compressor like UPX for instance. Once you compile it run upx and compress your executable. get it here

sorry about the link... get it at www.upx.sourceforge.net

Shrinking the size of an MFC app in VC++ 7.x is difficult. In VC++ 6.0, you could get it down to about 160k but not much more than that.
Since it's dialog based, I'd consider just converting it to a standard windows app and taking the parts of afxinet.h that you need.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

If you want to keep it small then I think you should avoid using MFC.... write a simple application without them...
Did you compiled your app using the static MFC library version? You cannot hope that who will use your installed has already the MFC Dlls

I've looked all over this site, and googled it but I can't seem to get the count function to work. here's what I have:
int iCount = count(vecWords.begin(),vecWords.end(),sWord)
where sWord is a struct variable of the type the vector is holding. I even try to hard-code a 1 or any other type of variable in there and I keep getting the same error message:
error C2678: binary '==' : no operator found which takes a left-hand operand of type 'std::allocator<_Ty>::value_type' (or there is no acceptable conversion)
Can anyone help? Thanks!!
If it's broken, I probably did it

Have you defined the == operator for the type used as your vector element?
|
|
|
|
|
NO, I haven't. thanks!! but can I define an '==' for a struct?

Sure:
struct foo
{
int x;
bool operator== ( const foo& rhs ) const
{
return x == rhs.x;
}
};

thanks; I knew how to make the overloaded operator, I'm just not that familiar with structs.;)

in C++, structs are only classes whose default attribute is public.
of course you can, and better, you must ! (in your case, if you want to use this function)

hi,
I'm trying to write my own mp3 player using DShow, since this point I've been able to let mp3 start,pause,stop and get duration of song, but I don't know where to start from for showing how times goes forward, need I to use threads or DirectShow provides a simple callback function?
thanks a lot

When you start a playback, first check the length of the song. Then calculate time in a seperate thread timer that runs on a second's interval. This allows you to track the position in the song. The idea is just that you start the timer at the same time when you begin playing.
If you have the DirectX SDK fully installed on your machine, you also get the documentations. Open up the DirectX C++ documentation, and look in the Contents. Go to DirectShow -> DirectShow Tutorials -> Implementing a Seek Bar. There's a concrete example on how to create a seek bar. If you don't have the docs, you can see this topic in the MSDN by following this link.
Happy reading.

I've got DirectX SDK Documentation, now I'll take a look, thanks a lot
