The link you gave me before didn't help. The code was in C++ not Boralnd C++ Builder. The two are very very different!
I'll try this one and let you know

thx

If it is a windows API, there must be someway to call the API from Borland C++.

Check in the documentation of BC++ if that API is supported.

Hi Mr.Prakash
As i told the others, i'm very new in Borland C++ and it would really help me if you could elaborate more or give me a complete code or anything as such. I don't know about what API you are talking about!

Many thanks,
Priya

Sorry, I haven't used BC++ since the early 90's. You're best off Googling or checking their documentation. (It may be worth the effort to switch to VC++ if this is possible).

29-Dec-05 18:10

i set up a program in C# using incrementing and decrementing information so i wanted to try to make this same program in C++ well so far i have it done all but the decrementer i have a

const int iPLEFT = 200; and under that i have

i have

const int iAP1 = 1; <-- i have this all the way up to 12

well the decrement i want to take the base 200 and subtract the iAP1-12 when the button is pushed

example.
i select the chosen name in my combo box then i click a button to add points. the incrementer will add 1 to the Ppoint1 label when there is 1 listed in the Ppoint1 label then i want the 200 to decrement 1 and so on.

also if anyone knows of some realy good MFC books that will help me learn and understand MFC / C++ programming. i realy enjoy learning to program so any extra information will be very helpfull

thank you for your time

lots of resources in the Codeproject

This is the way u capture bitmap from clipboard.

BOOL bRes = OpenClipboard();<br />
HBITMAP hBmp = (HBITMAP) GetClipboardData(CF_BITMAP);<br />
if ( hBmp != NULL )<br />
{<br />
      CClientDC dc(this);<br />
      HDC hDC = CreateCompatibleDC(NULL);<br />
      SelectObject(hDC, hBmp);<br />
      if ( !BitBlt(dc.m_hDC, 0, 0, 200, 200, hDC, 0, 0, SRCCOPY) )<br />
	AfxMessageBox("Err");<br />
}<br />
	<br />
bRes = CloseClipboard();

Saving the bmp into a file is simple as well. You can look into the MSDN. or below link on codeproject for saving HBITMAP to File.

does anyone how internet accelerators work, if they do, and what it would take to make a simple program to boost internet speed?
I have dsl and have seen a lot of programs that claim to speed internet speed and thought i would try to make one of my own (mostly for fun).

any help, includeing websites tutorial or ideas would be greatly appreciated.

thank you in advance for the help and happy new year!

Generally when a big file is downloaded say 1MB, the internet explorer downloads the file using one single socket i.e. serially, The problem with this approch is that the data back should come to you without wasting the bandwidth i.e. There should be no time gab between 2 packets.

So the accelerators opens more than one socket and downloads the file from different part of the file, i.e partial download, partial download is possible in http1.1 and also the server should support the partial download.

Downloading the same file from different offset, to some extend improves the bandwith utilization and hence improves the download time.

Check the GET HTTP request for more info, You might need to know the HTTP protocol for this too.
or google "partial get request"

Partial request can also be achived using FTP protocol, so the download accelerators uses either FTP or HTTP depending on the location of the content i.e. on http server or ftp server.

Printing Problem - Console App - C++ - VS2005

LudwigKeck29-Dec-05 12:00

I need a console app (it is called from various other programs) that processes some data from various files and at times needs to send data to a (let's say generic text) printer with some printer control instructions. I cam across a sample in the help files with starts:
Frown | :(

// RawDataToPrinter - sends binary data directly to a printer<br />
      // <br />
      // szPrinterName: NULL-terminated string specifying printer name<br />
      // lpData:        Pointer to raw data bytes<br />
      // dwCount        Length of lpData in bytes<br />
      // <br />
      // Returns: TRUE for success, FALSE for failure.<br />
      // <br />
      BOOL RawDataToPrinter(LPSTR szPrinterName, LPBYTE lpData, DWORD dwCount)<br />
      {<br />
        HANDLE     hPrinter;<br />
        DOC_INFO_1 DocInfo;<br />
        DWORD      dwJob;<br />
        DWORD      dwBytesWritten;<br />
<br />
        // Need a handle to the printer.<br />
        if( ! OpenPrinter( szPrinterName, &hPrinter, NULL ) )<br />
          return FALSE;<br />
       .....

This seemed to do what I need. I included WinNT.h and then the fun began: Compiling just presents a long list off errors in the WinNT.h file:
c:\program files\microsoft visual studio 8\vc\platformsdk\include\winnt.h(273) : error C2146: syntax error : missing ';' before identifier 'WCHAR'
c:\program files\microsoft visual studio 8\vc\platformsdk\include\winnt.h(273) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
c:\program files\microsoft visual studio 8\vc\platformsdk\include\winnt.h(276) : error C2143: syntax error : missing ';' before '*'
and many others.

Any ideas? Suggestions? -- Honestly I have not yet started to celebrate the new year!

Hi and belated Merry Christmas to everybody! I wish you all a Happy New Year and may it bring you all health and happyness and luck to your families.

Oh and yes, I do have a question: I got a VC++ 6 DLL project. Simple. Win32. How can I add a "Description", "Company Name" and "Version" to it?

Hi basementman. I can't really add a version resource 'cause as I said this is an emtpy win32 DLL project. It only holds a .cpp and a couple of Hs. Can I do it like this?? How can I add such a resource?

Hi,

I have a this problem that I don't succeed in connecting to another computer through the net, can anyone please help me?

I have two computers in different locations:
1) Both get the ip through the local computer name and then a call to gethostbyname and inet_ntoa. Is there a better way achieving the current ip?
2) I use a hub, how can I get my real IP and not what the hub gives me?
3) On the other computer a server listens on INADDR_ANY and a certain port, when I try to connect to it with the ip found in section 1, I fail after a timeout. I tried pinging the computer with the ip found, but it was unreachable. Can it be the ip is unreachable (even when the firewall is down)? What can be the problem? The socket connects without problems to sites on the internet and to the local computer ip.

thanks in advance,

O.

If you are behind a NAT server, you cannot really get your public IP, except by doing something externally like doing an HTTP connect to download a webpage that simply returns your IP address. For e.g., you could connect to www.whatismyip.com and download the index page, and then parse out the IP address from there.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
