Hi,
i would like to build a small program (to get into networking) that sends a
file to a server program and the server program should store the file locally.
You should then be able to download it again or another file that is on the server.
Now, i have worked with sockets before but only in a simple chat server/client program. How does one send a file over a socket? Do you cut the file in pieces and then send the pieces (in a loop) or is there a way to send the files in 1 time? (i can't see how) I have seen articles that talk about streaming an object. This sounds interesting as i mainly use an O.O. design. Any small samples around that show this kind of stuff?
Thanks,
BK

Look at the RFC959 for the official definition of the Ftp protocol. It does exactly what you are asking. The RFC will tell you how it does it. This stuff is pretty dense. There may be more accessible descriptions around, but I haven't seen them.

Hope this helps,

Take a look at the VNC project. VNC is a project created by AT&T. It's an open-source, cross-platform equivalent to pcAnywhere. It might be applicable to what you're doing.

I have to work with a large file with variable rows and columns and I want to make it into 1 large column so I can read all the data using the ReadString command i.e. I need to replace the spaces along each row with newlines(\n)'s. What can I use to do this? Any help would be much appreciated...

Well, I have a couple of solutions:
1) You could replace the spaces as you read the strings from the file
2) You could use CQStringParser, and let it parse each string as it's read into space-delimited fields, and the read the fields one at a time out of the object. Of course, you'd probably want to create an array of CQStringParser objects too.

What do I use to replace the spaces as I read the strings from the file? I am trying to use strtok at present with limited success. Thanks for your help by the way,

I wouldn't use strtok (mostly because I wrote the CQStringParser class).
If you're using CStdio, you're using MFC. If you're using MFC, CQStringParser would be abetter choice because it parses the strings for you without you having to do anything but instantiate an object with a string and a delimiter character.
Check out that class and see if it doesn't work better than strtok.
Besides all that, CString has a Replace() function that can replace all instances of one character with another.

Do you just need to make a one-time change to the file? (That's what it sounds like to me.) Install Perl from ActiveState and run this from the command line:
perl -pi.bak -e 's/\s+/\n/g' yourfile.txt
That replaces any group of 1+ spaces with a newline (and saves a backup in yourfile.txt.bak just in case).

Hi,
Can anyone reccomend a good replace for the MFC CDatabase and CRecordset classes? I am trying to port an MFC based database app to plain Win32 and I haven't been able to find anything powerful enough.
Cheers

Have you searched this site's Database section?
I can't recommend one specifically because I've never used anything except MFC's and my own portable class library. However, I must ask: why? Why go to plain Win32?
You may consider copying MFC's classes and "adapting" them as your own, since they wrap around the Win32 API.

You can use ADO. It is a COM object. Just create an instance and go to it.
Long ago (1995), I used a thing called DBLib. It was pretty primative. I don't know if its still avaialble.
Hope this helps,

I have added speech to one of my applications using the Microsoft SDK 5.0. It works on my development machine, but not on machines that do not have the SDK loaded. Are there files from the SDK that need to be added to the target machine?
|
|
|
|
|
Yes. They are described in the documentation for the SDK. If you are really documenation adverse, try running the DEPENDS utility that ships with VC. It will tell you all the things your program needs to run. Go to a standard configuration system and see which ones are missing. If this is for wide distribution, better go with the documentation.
P.S. Remember, when redistributing other peoples software, check the licensing agreements. This is especially true if you are developing commercial software and distributing Microsoft stuff.
Hope this helps,
Bill

I use a CHtmlView to display a web page,and i can use this code to get the IHTMLDocument2 interface pointer:
CDhtmlView * pView = (CDhtmlView *)GetActiveView();
LPDISPATCH pDispatch;
pDispatch = pView->GetHtmlDocument();
IHTMLDocument2 * pHTML;
pDispatch->QueryInterface(IID_IHTMLDocument2,(void **)&pHTML);
then i can use this pointer to do something.
but when a homepage use the to split into same frame. how i get the IHTMLDocument2 pointer of a homepage in a frame??
|
|
|
|
|
Call IHTMLDocument2::get_frames() to get a IHTMLFramesCollection2 interface. For each frame in the collection, query it for IHTMLWindow2, then call get_document(). (There's sample code in MSDN on the IHTMLFramesCollection2::item page.)

I want to read/write a unicode file. Is there a API through which I know whether the file is unicode or not, is there a file header for a unicode file. If this is not there, what is the function (string related) i need to use.
thanks

Here's some code I use to avoid using a UNICODE file in a non-unicode build (gpfs the kernel):
#if !defined(_UNICODE)
DWORD dwBytesRead;
ReadFile(hFile, szBuf, 4096*sizeof(TCHAR), &dwBytesRead, NULL);
if(dwBytesRead > 7) {
DWORD dwUnicode = IsTextUnicode(szBuf, dwBytesRead, NULL);
if(dwUnicode) {
m_bStringsLoaded = FALSE;
retval = MD_UNICODE_ERROR;
}
}
#endif
Not guaranteed to work for small strings - hence the '> 7' check (as if thats gonna help me!). Check the docs for IsTextUnicode - interesting stuff.

Thanks. It works For me.

I'm trying to use the windows media player active-x control in my app but i can't seem to load a file. This is what i have:
CString Movie = "C:\mymovie.avi";
m_cPlayer.SetFileName(Movie);
m_cPlayer.Play();
i tried to put "file:///" before the path because some web related stuff needs it, but that didn't work either. 
How do i load the file?
Thanks

The backslash should be typed twice:
CString Movie="C:\\mymovie.avi";
...

In msdn ,in "Recordset: Locking Records (ODBC)",It
said "Relatively few ODBC drivers currently support pessimistic locking."
How can I know my ODBC driver support pessimistic locking?
|
|
|
|
|
SQLGetInfo should do it.
