How to read File Attributes

Strange, as I use that function all the time on non-DC machines. What problem(s) are you seeing?

Hi all,

I want to read the attributes of a file. Sounds easy, but there must be more attributes that just "Hidden and "System" and so on.
If you open the properties of a file, then there is a property-page, where you can store the author of this document, a short description, keywords and so on. I want to read and write these informations. Can anyone tell me, how it is done?

Hello every one,
Please I need to know how is it possible to convert a decimal number to its binary, octal, and hex equivalents using C++ but without using predefined functions

The classical question Unsure | :~

... A number is neither binary, nor octal, nor hex, nor... It is just a number. What is binary or octal is its representation (so how you gonna print the value, to be 'readable' for a human).
A little example: if you have 31 apples on the table, you can say 'I have 31 apples' or 'I have 0x1F apples', you will still have the same number of apples.

So, you want to convert a number into a string ?

Which string ?
Could you be more explicit and explain what you are trying to do exactly ?

Here is a base-10 to base-2 converter:

// szBase2 must be at least 33 bytes
void DWORD_To_BinaryString( DWORD dwBase10, char szBase2[] )
{    
    for (int bit = 0; bit < 32; bit++) 
    {        
        DWORD dwMask = 0x80000000 >> bit;        
        
        if ((dwBase10 & dwMask ) == dwMask) 
            szBase2[bit] = '1';        
        else                        
            szBase2[bit] = '0';    
    }    
    
    szBase2[32] = '\0';
}

will this be ok??

<br />
int deci = 4;<br />
char binStr[10];<br />
binStr=itoa(deci,binStr,2); //2 for bin, 16 for hex <br />
<br />
printf("Binary:%s",binStr);<br />
<br />

ouput:
Binary: 100. Unsure | :~

It does not satisfy the "but without using predefined functions" requirement.

[OT] Re: SHBrowseForFolder - start up dir

8-May-06 4:50

i have 2 types of buttons in my app, ones i create dynamically using Create Method and by this the OnChildNotify with WM_CTLCOLORBTN working 100% ok. the other type is resource buttons, where i place them in my resource editor on my dialog, and then in my code i use
void CDlg::DoDataExchange(CDataExchange* pDX)
to add a member to my button with the type of MyButton....but in this situation, i don't see the font change??? i've i place a break point (in debug mode) i do step in the if (CTLCOLORBTN == message) and i see the selectobject with my phone, but the result is not font changing but the font i see in the resources...

any ideas?

thanks

Re: [OT] Re: SHBrowseForFolder - start up dir

That was a mistake on my part. The CFont object should be a member of the dialog, and created in the constructor. In OnInitDialog(), call SetFont() for each of the buttons.

Try:

CMyButton::CMyButton()
{
    LOGFONT lf = {0};

    _tcscpy(lf.lfFaceName, _T("MS Sans Serif"));
    lf.lfHeight = 28;
    lf.lfWeight = FW_BOLD;

    m_font.CreateFontIndirect(&lf);
}
 
void CMyButton::PreSubclassWindow() 
{
    SetFont(&m_font);	
    CButton::PreSubclassWindow();
}
