You can overwrite the PreTranslateMessage(...) method like this:

BOOL CYourDialog::PreTranslateMessage(MSG* pMsg)
{
	if ((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == VK_RETURN))
		return TRUE;
	return CDialog::PreTranslateMessage(pMsg);
}

I doubt that you may need to disable the enter key in a dialog application...

If so then you can override the void OnOK() in your dialog class and avoid the calling of CDialog::OnOK() inside it.

tray icon specifics?

What are the limit to putting an icon on the system tray?
what size?
how many colors?

Everytime I get new artwork from our designers, they look crappy on the system tray.
What parameters should I give them in order to make a decent icon?

size: 16x16
colors: I think in Win 2K you can use 256 colors; in previous OSes it was 16 colors max. XP probably supports 32-bit icons now, but I can't quite tell now since the shadows are hard to detect against the blue taskbar.

EnumPrinters in Service doesn't work

Hi All,

I read in one of the forums that an EnumPrinters() for Network printers when used in a service , does not work because the service is running under SYSTEM account.

This is the problem. can any of u give me some inputs on how to solve this.I need to use

EnumPrinters() from the service.

are there any access rights that need to be given to the SYSTEM Account ? If yes, how do we set them ?

Any solutions ?

Thanks for the help.

A SYSTEM account service typically does not have full access to the network.
You can run your service under a specific account that DOES have network access.
You can imersonate a specific account which has network access from within your service which is running under the SYSTEM account.

There isn't a "recycle bin folder", each drive has its own directory (\recycled or \recycler depending on the file system).

For Accessing Recycle bin simple method is to get all the drives of the hard disk using _getdrive() API. Each drive contains 'Recycled' folder. using it you can get the information of the files in the recycle bin.
If you know any best solution then plz send it.

Actually I through the source code of given link,
Infact what I need is to first overwrite the files which are present in Recycle Bin and then delete the file .
So the idea of SHEmptyRecycleBin() or from the source code of above sample does not fulfill my requirement.

So please tell me that how to overwrite the files that are in RECYCLE BIN.

Please Help.
Thanks

Hard Disk Free space

Hi,

I have to display the Hard Disk free space in the Edit box, can anyone plz tell what function we have to use for calculating Hard disk free space and didplaying it in a edit box in read only mode.

Regards,
Parichay.

Hi,

BOOL GetDiskFreeSpaceEx(
LPCTSTR lpDirectoryName,
PULARGE_INTEGER lpFreeBytesAvailable,
PULARGE_INTEGER lpTotalNumberOfBytes,
PULARGE_INTEGER lpTotalNumberOfFreeBytes
);

where:
lpDirectoryName - Pointer to a null-terminated string that specifies a directory on the disk of interest. If this parameter is NULL, the function uses the root of the current disk.

You can use i.e.:
std::stringstream sstr;

sstr << lpTotalNumberOfFreeBytes << _T( " bytes" );

SetWindowText( hWnd, sstr.str().c_str() );

where hWnd is a handle to editbox window.

Use the SendMessage() or SendDlgItemMessage() function passing along the text you want to enter as the lParam and WM_SETTEXT as the message.

So if project is MFC you can do:

std::stringstream sstr;

sstr << lpTotalNumberOfFreeBytes << _T( " bytes" );

GetDlgItem( IDC_SPACE )->SetWindowText( sstr.str().c_str() );
