For an easy way out, first read Xiangyang Liu's article Start Your Windows Programs From An NT Service[^]
This article presents you with a service, which is able to start programs before users log on and keep them running after users log off. This way, you don't need to ponder about how to implement MFC to a Win32 service. You can just write a full-fledged MFC application using the MFC App Wizard, and let the XYNTService worry about the rest.

Yeah,
I think I will go for that solution. Thank you so much for pointing that out to me.

Recently i did a packet capture on my network of what was being sent when i logged into my router and viewed the status page that has the current ip for my router (the ip for the internet side). To my surprise i saw a packet of the http connection that had some XML data in it, like the external ip-address for one. But then when i pressed refresh in IE, or i closed and relogged into my router it didnt send that XML data anymore. Now my question would be why is this? And is there any way i can surely get this XML reply from my router when i connect to it manually? (I don't know much about XML)
Thank you for any assistance.

I desperately need help on setting up and using the FlatSB with C, no MFC.
I, by all means know nothing about C++ (btw, sorry if i posted this here), and I just migrated from VB.
I found some samples, like JonathanLivingstone's sample (http://www.codeproject.com/dialog/ScrollableChildDialog/ScrollableChildDialog_demo.zip) which is exactly i wanted.
I need to scroll (with FlatSB) my dialog which has about 50 editboxes & labels.
I know how to do this with VB. I just need to use canvas to group all of these controls, and then scroll it.
But I don't know how to do these with win32 API & C.
Please help me! 
I really appreciate any help regarding this.

In my program I have 2 file:input and output.
When I open the first file I am reading the lines where
I have my specific string, other lines I am skiping.
In my output file I need to write my lines with tab delimeter.
How do I do this?

What are you using to read with: FILE*, istream, CFile, etc?
Five birds are sitting on a fence.
Three of them decide to fly off.

Then use ostream::write() to write the data to an output stream (e.g., file).

hello all,
my name is durval and i've the following problem in my project:
when the color-palette from the windows-desktop (properties)
16-bit (65536) is set. on ms-c++ print-preview (mfc) the
::StretchBlt(...)/::StretchDIBits(...)/::::BitBlt(...)
doesn't work properly. the bitmap is dividing in 2 parts, the
right (1/3 from the bitmap) will be put on the left place and
the left is displaced to the right.
at all the other color-settings there's no problem: 8-bit, 24-bit...
do you know this problem?
please, if everybody could help me, it would be very nice.
thanx a lot,
durval.
the code:
BOOL CDib::Draw(CDC* pDC, CPoint origin, CSize size)
{
if(m_lpBMIH == NULL) return FALSE;
if(m_hPalette != NULL)
::SelectPalette(pDC->GetSafeHdc(), m_hPalette, TRUE);
pDC->SetStretchBltMode(COLORONCOLOR);
// ::BitBlt( pDC->GetSafeHdc(), origin.x, origin.y, m_lpBMIH->biWidth, m_lpBMIH->biHeight, memDC.m_hDC, 0, 0, SRCCOPY );
// ::StretchBlt( pDC->GetSafeHdc(), origin.x, origin.y, size.cx, size.cy, memDC.m_hDC, 0, 0, m_lpBMIH->biWidth, m_lpBMIH->biHeight , SRCCOPY );
::StretchDIBits(pDC->GetSafeHdc(), origin.x, origin.y, size.cx, size.cy,
0, 0, m_lpBMIH->biWidth, m_lpBMIH->biHeight,
m_lpImage, (LPBITMAPINFO) m_lpBMIH, DIB_RGB_COLORS, SRCCOPY);
return TRUE;
}

Hi Guys,
I'm having a heck of a time doing some rounding here, hoping someone has a quick solution.
Example:
CHAR string[xx] = "1.019", null terminated string holding the current release.
FLOAT instver, intended to hold the float value of string ( I want it to be 1.019 )
When I do:
sscanf ( string, "%5lf", &instver );
My result is always: 1.0189999
I've tried:
instver = atof ( string );
And I still get the same results. I've done some peeking around the helpfile, can't find anything that will let me truncate/round the decimal spots.
Anybody?
Thx.
Mike.

You are always going to get this degradation of floating point accuracy. You need to read up on how floats are stored in IEEE 754 specification.
Floats are stored as a binary value that is composed of the mantissa and the exponent just like in regular scientific notation, however they are binary, so you are converting a decimal format into binary - this is going to cause round-off error.
It is still basicly fairly accurate. If it is just a cosmetic thing you can use format statements and they will round to the correct value for you. printf("%.3f", val); will do this.

 I'm trying to find "Exact Analysis of Merge sort"- M.Golin & R.Sedgewich - Fourth SIAM Conference on Discrete Mathmatics for my assignment. Could you show me where to find it or if you got it, please send to my email
azury_thanh@yahoo.com
Thank you so much 
Study is suffering!!

merge sort can be implemented in various ways but a very good way to do it is to use the Divide and Conquer Algo.
it divides the array into two.. then sorst the two seperately and then finally merge them back to get the final sorted one.
we use recursive divide calls to divide the array till we get the array with 2 or 1 element.
it runs in time O(n ln n)
if u need the code and the detailed analysis how to derive the complexity.. then mail me.
hope this satisfies u

I have created a lsitbox control, and got a database into MFC application. i am trying to display data from a particular field into the listbox.when i did this
CListBox* pListBox = static_cast<clistbox*> (GetDlgItem(IDC_COURSE));
pListBox->AddString(m_pSet->m_Course);
it is only showing the first one. how can i make display all, and let me choose from it.please let me know

How about a loop?

One solution is InsertItem().

Which would be for a list control, would it not?

Hi!
I have a dialog based project.
The first dialog is the login, the second the menu.
When I exit from the login (cancel), my thread exits with code 0.
But when I exit from the menu, I close my menu dialog with cancel, and automaticaly my login dialog with CDialog::OnOK(), and the thread exits with code 13.
I don't know where is my bug...
Thanks

Thread exit codes can be whatever you want. The fact that it's non-zero doesn't necessarily indicate an error, and in fact the return code of the main thread of a GUI app is generally not useful.

Hi,
I've subclassed a an edit control from CEdit.
below is what's in the header file:
class CMyEdit: public CEdit<br />
{<br />
public:<br />
void ChangeColour(const unsigned long &bg, const unsigned long &fg);<br />
protected:<br />
afx_msg HBRUSH OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor);<br />
<br />
DECLARE_MESSAGE_MAP()<br />
private:<br />
CBrush m_brush;<br />
unsigned long TextColour;<br />
unsigned long BKColour;<br />
CFont m_TextFont;<br />
};<br />
<br />
}<br />
the methods in my C++ files are:
HBRUSH CMyEdit::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) <br />
{<br />
HBRUSH hbr = CEdit::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
pDC->SetTextColor(TextColour);<br />
<br />
return m_brush;<br />
}<br />
<br />
void CMyEdit::ChangeColour(const unsigned long &fg, const unsigned long &bg)<br />
{<br />
TextColour = fg;<br />
BKColour = bg;<br />
m_brush.DeleteObject();<br />
m_brush.CreateSolidBrush(BKColour);<br />
Invalidate();<br />
My problem is why the method OnCtlColor is NOT being called?
Any explanations
Thanks, Alton

Have you set a reflection mapping up (ON_WM_CTLCOLOR_REFLECT) in the class's message map?

In my Cdialog based class, I have three buttons arranged vertically and centered in the dialog at design time. I dont do anything special to the class when I run it. It shows up with the right side of the dialog larger than the left side, i.e. the buttons are no longer horizontally centered. I can I guess do a runtime positioning with MoveWindow etc but am wondering why this is happening. ANything short of runtime positioning I can do at designtime to fix this?
Thanks,
ns

That shouldn't happen. Windows won't move/align your controls by itself.
