Hey, i used the following technique in my program to solve a same problem.
when you recieve WM_INITDIALOG message, call ShowWindow(hDlg,SW_SHOW); //plese write the MFC equivalent urself;P)
After that, you can call MessageBox to do your stuff...
That's simpler solution.
Remember... testing & debugging are always part of programming ...so exterminate those stinking bugs

Hi ,
When i use the scrollbars the position of the window also changes.
Can i attach my code instead of pasting it?
Thanks and regards,
Salil.

I have a form based application window and i need to make its size fixed.How do i do it.
|
|
|
|

I'm assuming you are using MFC and your app is using a CFormView derived class and not a CDialog class.
Add a handler for the WM_GETMINMAXINFO in your CMainFrame class.
void CMainFrame::OnGetMinMaxInfo(MINMAXINFO FAR* lpMMI) <br />
{<br />
lpMMI->ptMaxSize.x = 800;<br />
lpMMI->ptMaxSize.y = 600;<br />
lpMMI->ptMaxTrackSize.x = 800;<br />
lpMMI->ptMaxTrackSize.y = 600;<br />
lpMMI->ptMinTrackSize.x = 800;<br />
lpMMI->ptMinTrackSize.y = 600;<br />
CFrameWnd::OnGetMinMaxInfo(lpMMI);<br />
}

HI Friends,
I would like to know how to hide the row in list ctrl. I tried the CListCtrl::SetItemState(). I have used all nState, nMask parameter which arespecified in MSDN.
It was given in MSDN that to hide the row in List Ctrl we need to use the CListCtrl::SetItemState(...). BUt unfortunately I am not able to figure out how to use it. This is very urgent. Please help me!!!
Thanks in Advance.

Hi,
But it is given in MSDN that it is possible by using CListCtr::SetItemState(...). U please read MSDN help about the CListCtrl.
|
|
|
|
|
SetItemState does not change the fact whether the row is 'shown' or not. It only changes the state values for the row, which are the following, as quoted from the April 2004 MSDN:
- LVIS_CUT: The item is marked for a cut-and-paste operation.
- LVIS_DROPHILITED: The item is highlighted as a drag-and-drop target.
- LVIS_FOCUSED: The item has the focus, so it is surrounded by a standard focus rectangle. Although more than one item may be selected, only one item can have the focus.
- LVIS_SELECTED: The item is selected. The appearance of a selected item depends on whether it has the focus and also on the system colors used for selection. Items will only show as selected if the list-view control has focus or the LVS_SHOWSELALWAYS style is used.
If you need to 'hide' a row, you must delete the corresponding item.
Software Zen: delete this;

Hi all,
Is it possible to MONITORING system activity such as file copying.?
I want to know what happens when a file is copied from one place to another place.How windows Copy or Cut a file from one place to another place.is it possible to HOOK this process.?
Thanks.

|

|

I think there is something called ICopyHook interface if you implement the interface and register the component the right way you can monitor the copying process.

ICopyHook is only for folders not for files
for files one will have to write a system driver
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

no wonder it didnt work for me when i was doing file copy operation.

where is the problem guys?!
just open the file with no share rights, then no other app can open/copy/delete/move/.. 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)

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

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?

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.
