Administration Rights for my Application by Token

Hi,

because of the CRegistry class and some other classes in my Application I need to have Administration rights for it. I want to have the same effect like set the "Run programm as Administrator" checkbox in the compatibility options of my Application, but in my Visual C++ code. I`m using the Visual Studio 2008.

I discovered, that AdjustTokenPrivileges is the function I probably need, but I don`t understand how to use it.

I get my token using the following lines:

HANDLE hToken = NULL;

if (!OpenProcessToken(GetCurrentProcess(), TOKEN_DUPLICATE,&hToken)) {
	AfxMessageBox("Error");
}

CloseHandle(hToken);

But I don`t know how to set the Privileges to the token, and I don`t understand how to set it for my whole application?

Can someone help me?

Thank you!

Try it

However, I hold it in a service code, that is started by SYSTEM user...
(Die Funktion aktiviert eine existierende Begünstigung,
verteilt aber nichts, wenn diese für den Benutzer nicht vorhanden ist)

BOOL AdjustTokenPrivileges(LPCTSTR lpName)
{
  BOOL bRes = TRUE;

  HANDLE hToken;
  if (OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken)) {
    LUID luid;
    if (LookupPrivilegeValue(NULL, lpName, &luid)) {
      TOKEN_PRIVILEGES tp;
      tp.PrivilegeCount = 1;
      tp.Privileges[0].Luid = luid;
      tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;

      if (!::AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), NULL, NULL)) {
        bRes = FALSE;
      }
    } else {
      bRes = FALSE;
    }
    CloseHandle(hToken);
  } else {
    bRes = FALSE;
  }

  return bRes;
}
 
void Usage()
{
  AdjustTokenPrivileges(SE_RESTORE_NAME);
  AdjustTokenPrivileges(SE_BACKUP_NAME);
...
}

WM_GETFONT returns NULL

I need to get the font of a static control, but the documentation says WM_GETFONT will return null if the control is using the system font. How can I get the system font?

[Edit]
I see GetStockObject can return the font, but there are many options. Which one of those do I need:

DEVICE_DEFAULT_FONT Windows NT/2000/XP: Device-dependent font.
DEFAULT_GUI_FONT Default font for user interface objects such as menus and dialog boxes. This is MS Sans Serif. Compare this with SYSTEM_FONT.
OEM_FIXED_FONT Original equipment manufacturer (OEM) dependent fixed-pitch (monospace) font.
SYSTEM_FONT System font. By default, the system uses the system font to draw menus, dialog box controls, and text.
Windows 95/98 and Windows NT: The system font is MS Sans Serif.

Windows 2000/XP: The system font is Tahoma

SYSTEM_FIXED_FONT Fixed-pitch (monospace) system font. This stock object is provided only for compatibility with 16-bit Windows versions earlier than 3.0.

We've been using GetStockObject(DEFAULT_GUI_FONT) and that has worked from Win95 to Windows 7. What do you need it for?

Thanks. I derive a class from cstatic with functions for changing font size and name. I do it by calling CWnd::GetFont, changing what I need and then calling CWnd::SetFont

HTML Editing Control for Win32

Can anyone suggest a library/control for editing HTML that can be added to a program written in C/C++ that only uses the Windows API (no MFC etc). We currently use nBit's HTML Editor OCX[^] but this has some small issues and hasn't been updated since 2006. The library/control will need to be royalty free.

No Method for Changing CMFCRibbonPanel Control Name Dynamically

CMFCRibbonPanel class do not implement any method for changing the control name at running time,
I think there should be a method like CMFCRibbonPanel::SetName since there is method like CMFCRibbonPanel::GetName so How could we change the name of this control dynamically?

0. Try the SetWindowText(..) function
1. Debug the drawing of the text and find an access to the found member Smile | :)

Use a Boolean member variable in your dlg class and initialise it as FALSE. Set it as TRUE in left button Down event. Then check it in the mouse move. If it is true then redraw the dlg contents. Also set it as FALSE in the left button up event.

eg:

BOOL m_bClicked=FALSE;

	LRESULT OnLButtonDown(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
	{
		m_bClicked=TRUE;
		
		return 0;
	}
	LRESULT OnLButtonUP(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
	{
		m_bClicked=FALSE;


		return 0;
	}

        LRESULT OnMouseMove(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
        {
                if(m_bClicked)
                {
                      //redraw code
                }
        }

What is the Base class of your dialog? Is it CDialog? Or is it a class derived from CDialog?

Re: problem on resize and move dialog window

If possible please post the code.. Smile | :)

Actually you need not handle any of these messages, because CDialog will do it for you.
This post is duplicate post of your previous question.didn't the solution posted in previous question help you. I have created a sample, and it's working fine
