Look for WM_POWERBROADCAST
and return BROADCAST_QUERY_DENY
<br />
case WM_POWERBROADCAST:<br />
MessageBox (hWnd, "Colsing Why, We've just met ","System CLosing??",0);<br />
return BROADCAST_QUERY_DENY;<br />

I would like to encyrpt the contents of my program before I write them to a file. How do I go about encypting the data before I write it to a file, (at the minute I am using serialization). One limitation is that I don't want to serialize the data to a temporary file and then encrypt the file as if the unencrypted file still exists then the data is not secure.
Could someone please just get me started, as I am not sure where to look as many encryption tutorials on this site encrypt and decrypt a file that already exists, I want to encrypt data in memory and write it to a file encrypted, then read the encrypted data back into the program's memory.
Thanks a lot

>> then the data is not secure.
secure from what? Depending on the definition of "secure" it can be almost impossible to accomplish.
>> many encryption tutorials on this site encrypt and decrypt a
>> file that already exists
Ok but at least one of them encrypts the data in memory and then writes it to the file. So that would show you how to do it yes?

If it's sufficient to just encrypt plain text data, you could encrypt your CStrings before writing them out and after reading them in.

Start by reading Applied Cryptography. Otherwise you will miss something subtile about encryption and get no benifit.

I have a MonthCalCtrl control in a dialog box. I want to set the daystates for the Month Cal Ctrl, the thing is I have a CArray of COleDateTime objects, and I'm not sure how to best set the daystates. Should I respond to the MCN_GETDAYSTATE message, and just update the visible months, or is there a way to set all of the daystates (visible or not) in the CDialog::OnInitDialog() function?
Any suggestions welcome,
Thanks

That would be dependant on the use model for your application.

Hi!
I currently write an application as a server that translate user uploaded office files into html or pdf. I write it in VB now, but I am also a VC coder.
My trouble is office will pop up dialog and wait for user to response sometimes. I trace the problems and do some prepare to make it not pop up. But I think I can't trace all the reasons to make office pop up. Is there any solution to make office work without asking question? I can accept it dont process on some file, but can't accept it stop working and have to press a button by human.
If there isn't such a solution. I think I have to use another "police" server that kill the application and recreate a new process when the application seems blocked and don't work for a long time.
I really wanna an elegant solution. Can any guru give me some suggestion?

Create a CRichEditCtrl member variable and then use SetWindowText().

thanks for your simple response
but now i'm trying to put text in a rich edit control
while accessing the way i put it there .
i mean how i can put text at a line number and a column i wish (example line 5 column 20 ) ?
setwindowtext() is good for one line rich edit
but i have a multiline rich edit box .so i need a way to write text in it
how i wish .
Strangely there is no function in rich edit class to do it (except SetWindowText() ) or maybe i dont know because i searched MSDN entirely but nothing found .
lots of thanks

SetWindowText() can be used, but you'll either need to call GetWindowText(), or have the text stored in a separate buffer. For example:
CString strBuffer1;
...
strBuffer1 = strBuffer1 + "\r\n" + ...
m_edit.SetWindowText(strBuffer1); The other way would look like:
CString strBuffer2;
m_edit.GetWindowText(strBuffer1);
strBuffer2 = strBuffer1 + "\r\n" + ...
m_edit.SetWindowText(strBuffer2); You can also use ReplaceSel().

I have hyperlink that is more than 50 character
when I specify it as the following to launch the outlook
CString str_content = "click here";
ShellExecute( NULL, "Open", "mailto:my@domain.com?Body=" + str_content, NULL, NULL, SW_SHOWNORMAL );
If i have shorter str_content and I launch, I can see hyperlink in
my outlook. However, if str_content becomes longer just text displayed in outlook content with all hyperlink code.
How can i get the hyperlink in outlook when i have longer string.

Hi,
Hope this helps
Retrieving the owner of a file requires:
obtain the security descriptor for the file, Use GetFileSecurity()
then using the security descriptor to get a pointer to the owner's Security Identifier (SID). GetSecurityDescriptorOwner()
Finally, you use the owner's SID to obtain the owner and domain name of the file LookupAccountSid()
Cheers

When a multiplayer game server outputs commands to your computer, where do they go? Is it possible to catch and log them?

It depends on the protocol used.
Run Network monitor and view the activity on your machine. Then save captured data to cap files.
