Hi DavidCrow
You solved my problem. ruilin = mrby123
Thanks
By the way, I do not like the f_ptr1.getline (par1,par2,par3); I do not like to
specify the number of the characters or the third parameter ' '.
I like to use the string function: getline(f_ptr1,s), This looks more robust,
but it does not work. The compile do not know the function, even you can see
I have #include string
The program is funny, when I put #include iostream and #include fstream
I got :'ifstream' : undeclared identifier
I have to put: #include iostream.h and #include fstream.h
Then the program works. I do not understand why I can not use #include iostream.

You might want to start with a VC++ compiler.

I am using VC++ compiler.
My intention is to read a file completely. So my intension is to read until
the end of the file. I do not know what is the best symbol to put at
while(!(qq=="'\n'")). I tried a few symbols, does't help.
Thanks

Hi,
I currently porting some code from Linux to Windows. I have decided against a windows implementation of the POSIX threading libraries and opted for windows threading.
Previously in my code, I had conditional run conditions using the pthread_cond_t, is there an equivalent in the windows threading API?
Any help would be greatly appreciated,
Paul.

That was a mistake

Unfortunatelly, no, at least not directly. Look here[^] for a workaround.

Thanks for your reply, that link is useful. I did try using the win32 pthread libraries, but I kept getting exception errors. The code functions correctly on linux but not with the win32 pthreads library. The decision was made above me to use windows threading api.
Thanks again.
Paul.

1. barcode is drawn by lines (space and bar), why does it need font? font is useless when we draw lines.
2. what is correct width of bar or space? - i.e. 0.2 mm etc.
3. what is correct height of barcode?

See here.

A barcode is comprised of bars and spaces. I believe the leftmost bar, which is one unit wide, sets the stage for the remaining bars and spaces.
includeh10 wrote: 3. what is correct height of barcode?
I believe it is governed by the product on which the barcode is placed. For example, a large box can afford to have a large barcode where as box of cookies could not. Another determining factor is how far will the scanner be from the box.

I'm writing an application, where I need to save links to external documents (.xls, .doc, .txt, ...). In Windows, when I double-click to such a file, it'll be opened automatically by the corresponding application.
double-click to test.xls opens Microsoft Excel
double-click to test.doc opens Microsoft Word
double-click to test.tif opens the corresponding graphical application
and so on...
How can I implement this functionality in my application, working under Visual C++ / MFC ?
regards

a type of file (extension) is associated with an application.
u can find all info about this in system register (run regedit.exe).
e.g. doc file can be opened by Microsoft word.

Use ShellExecute() with the "open" verb will open the associated application.
Otherwise, if you are wanting to know how to register your own file type, this is handled for you automatically by MFC's AppWizard. It will create a .reg file in your project that can be merged on the target machine. Check out CWinApp::EnableShellOpen() and CWinApp::RegisterShellFileTypes().

This is code I've used successfully in the past:
WSADATA wsaData;
DWORD dwResult,
dwCount = 0xffffffff,
dwBufferSize = 16384;
HANDLE hEnum;
LPVOID lpBuffer;
LPNETRESOURCE lpNetResource = NULL;
dwResult = WSAStartup(MAKEWORD(1, 1), &wsaData);
if (0 == dwResult)
{
dwResult = WNetOpenEnum(RESOURCE_CONTEXT, RESOURCETYPE_ANY, NULL, NULL, &hEnum);
if (NO_ERROR == dwResult && NULL != hEnum)
{
lpBuffer = new BYTE[dwBufferSize];
dwResult = WNetEnumResource(hEnum, &dwCount, lpBuffer, &dwBufferSize);
if (NO_ERROR == dwResult && dwCount > 0)
{
lpNetResource = (LPNETRESOURCE) lpBuffer;
while (NULL != lpNetResource)
{
...
lpNetResource++;
}
}
delete [] lpBuffer;
}
dwResult = WSACleanup();
}

Hi All,
I have an utility programme that uses wchar_t. However interfacing to our programme which uses char's is a problem.
How does one convert to wchar_t to char, and visa versa?

Rich
