Re: How do I traget the Every one permission in Windows using VC 6.0 or 7.0

Why are you trying to do this? And by the way this is not possible at all.
This is how the usermgmt of NT was designed. If You create an user he must recieve
some initial rights. So everyone was introduced.

All I want to do is to write a script that will modify they rights of the everyone group. Which you can do on any object by going to it's security page. all I am tyying to do is automate this process which I know is possible because when edit an objects security page all you are doing is executing a series of API functions and any API function is accessible from C++ I know I cannot delete the everyone group but I also know I can assign rights to the everyone group and this is what I want to do please help

Hiya I am looking to see if I have SourceSafe 6.0 ( that ships with .net - Enterprise developer - which is what I have ) installed...

Does anyone know where abouts it is in the MICROSOFT VISUAL STUDIO.NET directory.

Also where can I get info on using it.

Thanks,

SourceSafe 6.0 was only marginally updated for .NET. As a result, it installs in

\Program Files\Microsoft Visual Studio

(no .NET) by default.

I have an MFC dialog app that has a Webbrowser object in it. I put a bitmap as a background to that application and now whenever something covers my dialog app, the webbrowser control doesn't get redrawn. How can I fix this problem? This is probably an easy question for many of you to solve, but embarrassingly it has left me scratching my head for the last half-hour.

Your help in answering my question will be greatly appreciated. Thanks in advance. Smile | :)

I stumbled across an MSDN entry recently about something like this but I can't seem to find it now... Frown | :-(

IIRC, the problem was related to the control's or the parent window's style not being set properly - you needed to add or remove WS_CLIPCHILDREN or WS_CLIPSIBLINGS. Something like that.

Sorry for being so vague. HTH.

I think the problem is the dialog has the CS_HREDRAW and CS_VREDRAW styles by default. In CDialog::PreCreateWindow register a new class without these styles. This will prevent the erasing of the entire window which is what these flags do when you move the window or some window comes on top. Now your browser control should hopefully stop behaving nastily Smile | :)

ceil and floor?

Hi,

I have a bit of code that does this ...

<br />
X = (int)ceil( phi*y );<br />
Y = (int)floor( delta*pi );<br />

... but I get compile error C2065: 'floor' : undeclared identifier and
error C2065: 'ceil' : undeclared identifier.

Do I need to include some file or something?

stdafx.h question

I understand that all *.cpp files in Visual C++ must
start with ...

<br />
#include "stdafx.h"<br />

... how can I make my C++ code portable with such
a restriction?

I tried this ...

<br />
#ifndef GNU<br />
#include "stdafx.h"<br />
#endif<br />

... but that doesn't seem to work.

What should I do if I want my code to compile under
more than ONE compiler?

For portable files you probably don'twant to use stdafx.h, which means no precompiled headers. Just set the Precompiled Headers switch for such files to "Not using precompiled headers".

I feel inadequate ... CButton question.

I fell so dumb and inadequate today ... yesterday was such a good day!

I have a CButton derived button in a dialog ( a dialog app ) :

// .h
#include "MyButton.h"
//{{AFX_DATA(CTestColorControlDlg)
 CMyButton m_HelpButton;
//}}AFX_DATA

and

// .cpp 
...
void CTestColorControlDlg::DoDataExchange(CDataExchange* pDX)
{
 CDialog::DoDataExchange(pDX);
 //{{AFX_DATA_MAP(CTestColorControlDlg)
 DDX_Control(pDX, IDC_HELP_BUTTON, m_HelpButton);
 //}}AFX_DATA_MAP
}
...

My button is working nicelly, but I don't receive and message for WM_CREATE, or even the OnCreate virtual is not called.

I need to change the button size, from inside the class, at creation time; I don't want to have to manually create the button in the dialog's OnInitDialog just to do it.

Thank yo for helping a programmer in need!

You don't get the WM_CREATE message because windows creates a normal button first, and then subclasses it in the first call to the DoDataExchange method. When your class is attached to the button, the button has already been created.

You may be able to do want you want in the PreSubclassWindow() virtual method - this is called after the HWND is attached to your button, but before the window procedure has been replaced.

Controls created via a dialog template do not recieve the WM_CREATE message. Handle all control initialization in PreSubclassWindow() instead.

Hello,
I am trying to use SHGetFolderPath in MFC app, however, I get error C2065: 'SHGetFolderPath' : undeclared identifier.

I have latest SDK, WinXP, and included the required header file shlobj.h.

if(SUCCEEDED(SHGetFolderPath(NULL, CSIDL_HISTORY, NULL, 0, lpPath)))<br />
		{<br />
			::SetCurrentDirectory(lpPath); 	//set current directory<br />
		}

Why can't the linker find this shell function?
