It should be fine - you can't/shouldn't be calling BeginPaint()/EndPaint() for WM_NCPAINT, so i don't know what the problem would be.

i have a freeware which can download a large file by breaking it into pieces.
eg. for a 100M file, the software breaks it into 10 pieces and downloads them togather, then combines them into one.

I am interested about tech used by the software - i need to develop an auto-download software for a company now - i want to use the same tech for downloading.

any links or comments?

thanks

How to get the HTTP visit?

I want to get the HTTP visit in my computer, which OS is windows 2000 and has IIS.
I create a program that uses socket to listen 80 port every second, but nothing captured.
Should I close the IIS or listen HTML format?
How to get it?
Thanks!

Can you please explain a little bit more what do you mean by "visit"?! In case you're trying to create a server-type application that listens for the 80 port (which by the way is HTTP) then you should disable IIS or re-direct IIS on a different port than 80 because the two would be attempting to do the same task. Then you should have your application always listen to port 80 (every second doesn't seem like a good ideea -- it's a two seldom)

I'd advise you to check out some documentation on writing TCP/IP client/server applications.. there are a ton of examples out there and just do a bit of readion on how a server works before you decide what to do with your app!

Using a VC7.1 dll in VC6?

John M. Drescher27-Sep-05 4:17

27-Sep-05 4:17

I want to create an unmanaged VC7.1 dll and use it with VC6? Is this possible? Although my app is MFC the dll does not require any MFC at all. The reason for my question is I would like to use some boost code that does not compile with vc6 in an application that would take too much effort to port to vc7. I know I would have to keep the boost code internal to the dll but that is ok for my application.

Answering my own question...

Well that works. I created a w32 dll in VC7 and linked and executed it from a VC6 application without any problems at all. Big Grin | :-D

I did not add boost to the vc7 dll but I'm sure that would work too.

Hi ALL,
I have created a Win32 Simple DLL project in VC++ 6. But although it is producing the .DLL file it is not producing the .LIB file. I don't know what is the problem. Please help me out.

If a DLL has no exports, the linker will not generate a .lib file. See http://msdn.microsoft.com/library/en-us/vccore/html/vcurfLinkerPropertyPages.asp[^]

Line spacing in DrawText

Hi,

I'm using DrawText(...) fn to draw multiline text.
Can I increase the default line spacing with out changing the text size?
I can't replace the DrawText to TextOut because I need DT_WORDBREAK and DT_CALCRECT.

I would calculate where each line of text will break, create a new string for the new length and draw each line of text independently - then adjust the lpRect to move down the desired spacing.

Will this work:

COLORREF clrCtlBk = pWinState->m_hDlgBkBrush;
COLORREF clrCtlText = pWinState->m_crDlgTextClr

I got a different way to get these colors!

I sent WM_CTLCOLORDLG to parent and used the brush returned.

HBRUSH hBrush = (HBRUSH) pWndParent->SendMessage(
 WM_CTLCOLORDLG,
 WPARAM( dcMem.GetSafeHdc()),
 LPARAM( m_hWnd ));
::FillRect( dcMem, &rt, hBrush );

For static texts

HBRUSH hBrush = (HBRUSH) pWndParent->SendMessage(
 WM_CTLCOLORSTATIC,
 WPARAM( dcMem.GetSafeHdc()),
 LPARAM( m_hWnd ));
::FillRect( dcMem, &rt, hBrush );

I have a little fear about bugs!
Could you please tell me that it is bug free?

Thank you.

No, Excel is not a database. However, using ADO, you can access it like it is. As far as the exporting goes, if you're using automation, there are functions for transferring an Access table to Excel, I don't know about the reverse.
