where is the problem guys?!
just open the file with no share rights, then no other app can open/copy/delete/move/.. it.
Don't try it, just do it!

Does anyone know where I can learn how to make an SMTP Server in C++ (no MFC please!!)
wWw.KruncherInc.com - My cool programs
|

Start with RFC Spec for SMTP server.
Then create a window Service.
Listen for incoming connection at port 25 ( i guess)
Spin off thread for each connection made and process the requests...
I guess these points are good enough to start with the design.

You need to find the RFCs for SMTP, Internet Message Format, and MIME etc.
From a programming pov there are three areas, a TCP server, a protocol implementation and mail processing. It's quite a big job.
I built a special purpose SMTP server last autumn using boost::spirit for the protocol parsing. I'd definitely recommend a proper parser here. I rolled my own TCP server utilising the Windows thread pool and IOCompletion Ports. Works well. This bit will be freely available for most uses soonish.

CHtmlEditCtrl is a new class introduced since MFC 7.0. It sounds like a great class, which can be used in dialogs for WYSIWYG html editing. But I have a big problem in using CHtmlEditCtrl::SetDocumentHTML after its creation:
<br />
BOOL CTestDlg::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
CString str = "<html><head><title>My page</title></head><body><p>test</p></body></html>";<br />
<br />
CHtmlEditCtrl* m_pHtmlEditor = new CHtmlEditCtrl();<br />
m_pHtmlEditor ->Create("",0,CRect(10,10,200,200),this,IDC_HTMLEDITOR);<br />
<br />
m_pHtmlEditor->SetDocumentHTML(str);<br />
<br />
return TRUE; <br />
}
Everything looks good, but when I run the app, the HTML code in "str" does not show up in the HTML Editor window  i.e., the html editor window is blank after the dialog appears on the screen.
What's more "interesting" (and frustrating) is, if I put a MessageBox before
m_pHtmlEditor->SetDocumentHTML(str);
i.e., change the code to:
<br />
BOOL CTestDlg::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
CString str = "<html><head><title>My page</title></head><body><p>test</p></body></html>";<br />
<br />
CHtmlEditCtrl* m_pHtmlEditor = new CHtmlEditCtrl();<br />
m_pHtmlEditor ->Create("",0,CRect(10,10,200,200),this,IDC_HTMLEDITOR);<br />
<br />
AfxMessageBox("test"); <br />
m_pHtmlEditor->SetDocumentHTML(str);<br />
<br />
return TRUE; <br />
}
It then works! The HTML code in "str" is showing up in the HTML editor window. But I really don't need that MessageBox.
Anybody has any idea? I am really stuck. I can provide a link to my test project if anyone needs it.
Big thanks! ![Rose | [Rose]](https://codeproject.freetls.fastly.net/script/Forums/Images/rose.gif)

Did you find any solution for this problem??

The Below code was able to take 2 char's from an array stream and turn it into an integer # and Convert it to Decimal.
However, unless I am missing something here, what it fails to do is the other half of what my problem was, that I wanted to take those 2 chars from the array stream and just convert them to an int value and leave them be, not convert them to decimal. I tried to do it myself, but it wasn't coming out correct.
Thank You

I don't understand what you're asking there. What's the expected behavior and how is it not working?

The above code takes 2 chars from the array and converts them to an int value.
However (and I proved this by running the code) it also converts the new int value from HEX to Decimal.
That helped me in one situation, but another situation where I dont want to convert that new int value from HEX to Dec, but need it to stay a HEX Value it doesnt help.
Hopefully someone understands what I am saying and can help.
Thanks

You dont convert from hex to decimal, they are just different ways of representing the same thing. In your case, you are outputting an 'int' variable to cout. Unless you tell cout otherwise, it will always display this as a decimal. If you want to display it as hex, then you need:
cout << hex << myNumber;
|
|
|
|

You can mofify the code as follows:
int Convert(char a, char b){
int intTemp=0;
char strBuffer[3];
strBuffer[0] = a;
strBuffer[1] = b;
strBuffer[2] = '\0';
sscanf(strBuffer,"%2x",&intTemp);
return intTemp;
}
This returns the HEX'ab' int value. The HEX or Decimal or Octal or whatever is just a representation of an integer number. What is exactly your problem?

Each of these functions returns a pointer to string. There is no error return.
Parameters

Base of value; must be in the range 2 – 36
Remarks
The _itoa, _i64toa, and _ui64toa function convert the digits of the given value argument to a null-terminated character string and stores the result (up to 33 bytes) in string. If radix equals 10 and value is negative, the first character of the stored string is the minus sign ( – ). _itow, _i64tow, and _ui64tow are wide-character versions of _itoa, _i64toa, and _ui64toa respectively.

how to add a formatted CString value to the original value, e.g: how to achieve these logical statements?!
CString str;
str += str.Format(" qer23 %d asdgsgd", var);
|
|
|
|
|
str.Format(...) doesn't return a string, it reassigns to str in-place. You'll need to use a second variable for the Format() call and append that to str.

Pinky, are you pondering what I'm pondering?
I think so Brain, but how will we fit the hamster inside the accordion?

You must use another variable for this purpose.
CString str, strTemp;
strTemp.Format(" qer23 %d asdgsgd", var);
str += strTemp;

This approach won't work.
To quote from the MSDN documentation for CString::Format()
The call will fail if the string object itself is offered as a parameter to Format. For example, the following code:
CString str = "Some Data";
str.Format("%s%d", str, 123); // Attention: str is also used in the parameter list.
will cause unpredictable results.

|
|
|
|
yeah sounds logical, coz its working on the same object, i assumed that a copy of the parameter would be made.

If you are using VS.NET 2002 or later, the CString class includes the member function AppendFormat, which does what you are asking.
If you are using VC6, you will need to do something like this:
CString str,tmp;
str = ";kj;lak;sajlg";
tmp.Format(" qer23 %d asdgsgd", var);
str += tmp;

Override PreCreateWindow and add WM_VSCROLL as shown below:
cs.style |= WS_VSCROLL;
Hope this helps.

try looking up strtok(), sample usage in MSDN library.

Use strchr or strtok.
