You can't.
If the LPVOID points to character data, you can create a CString from that data. You'd need
to know the type of the characters (char or wchar_t) so the appropriate constructor is called.
Something like these should work:
// LPVOID pVoid = ...;
// pVoid points to unicode characters, null terminated
CString str((wchar_t *)pVoid);
// pVoid points to ANSI characters, null terminated
CString str((char *)pVoid);
If the character data is not null-terminated and you know the length, there's CString constructors
which take a length (int) as a second parameter.

How many controls do you have on the form?

I think you must add some member in header file , for example : in following
code , when you want add double click to add a new member in dialog, the
"Cannot add new member " message will be occur. please move the
private:
int m_iValue
below the ADX_DATA will be fixed!
// Dialog Data
//{{AFX_DATA(CDlg)
enum { IDD = IDD_DIALOG };
CButton m_ABC;
CRichEditCtrl m_RichEdit;
private:
int m_iValue
//}}AFX_DATA
Also this inidicates that the file is readonly, or that perhaps the various magic comments have
been corrupted

hello,
I want to create a dynamic Bitmap (size + data), what is the way doing this?
I try to use CreateBitmap without big success.
Thanks.

Can you more explain about create a dynamic Bitmap

Please use the following code if u can use MFC.
UINT BITS_IN_A_BYTE = 8;
CBitmap BlankBmp;
BYTE *pbyBits = 0;
SIZE_T nBits;
nBits = m_uImgWidth * m_uImgHeight;
pbyBits = new BYTE[nBits + UNITY];
if( 0 == pbyBits )
{
return;
}
// Fill it with Black RGB values (R=0, G=0, B=0)
ZeroMemory( pbyBits, nBits + UNITY );
BlankBmp.CreateBitmap( m_uImgWidth, m_uImgHeight,
1, BITS_IN_A_BYTE, pbyBits );
delete[] pbyBits;

Using Win32 APIs or MFC? Do you want a DIB, DDB, or a DIB section?

Hi,
use "WTSRegisterSessionNotification()" to register your window to receive
the notification "WM_WTSSESSION_CHANGE" which has "WTS_SESSION_LOCK" & "WTS_SESSION_UNLOCK" parameter to identify that.
Best Regards
Raj

Implement the ISensLogon interface. The DisplayLock() and DisplayUnLock() methods are of interest to you.
