Guys,
Is there an api that sends a file over the network between two computers using their computer names. Can someone give me guidance on how to do this.
Regards,
SAK

In C++, you would use CSocket class or a derivative.
One application would be the server, and listen for client(s) to connect on a given port.
The other app would be the client(s) and try to connect to a server by name and port.
Hint: if you are testing on 1 pc, hostname of "loopback" is valid.
Once a connection has been established, the client opens and Sends the file, and the server's Receive handles the incoming data packets, writing them to a file.
I suggest reading the online help on sockets.
There are also user-written wrapper classes for sockets you could examine.

Rick,
Thank you for the help, I was pretty sure I needed to use sockets (something I am not familiar with) but was hoping there was an API for this. Anyways, I am going see if I can learn how to use sockets. Thanks again for the response.

There is an API that uses the Windows File Manager (or how they call it) that can copy files or directories to a remote computer over the network, if it has a shared directory with full rights. E.g. it will copy the file to \\Destination_Comp\Directory\. If you are interested, I can tell you how it works.

TCHAR pszFrom[1024] = {0};
TCHAR pszTo[1024] = {0};
SHFILEOPSTRUCT shfo;
GetDlgItemText( IDC_SOURCE, pszFrom, 1024);
GetDlgItemText( IDC_DEST, pszTo, 1024);
ZeroMemory(&shfo, sizeof(SHFILEOPSTRUCT));
shfo.hwnd = AfxGetApp()->m_pMainWnd->m_hWnd;
shfo.wFunc = FO_COPY;
shfo.pFrom = pszFrom;
shfo.pTo = pszTo;
shfo.fFlags = FOF_NOCONFIRMATION | FOF_SILENT;
SHFileOperation(&shfo);
This is how it works for me  you can see more detailed info about SHFILEOPSTRUCT in the MSDN online reference...
If any questions, do not hesitate to ask...

The online help for each method describes which headers and libraries are required. Quite a few are different for NT than 9x.
You could create a new Build configuration for NT, and include the required libraries. That way you could still build for 9x and test.

OK... I had a program (originally written using VC 6.0) that, as part of its function, retrieves values from an open Internet Explorer window. However, when I compile the SAME EXACT code that works in VC6 in VS.NET, the retrieve function fails.
In the code, once I get the IE window, I check for frames:
IDispatchPtr dis;
IHTMLDocument2Ptr doc;
spBrowser->get_Document(&dis); //spBrowser is earlier declared and initialized
dis->QueryInterface(&doc);
IHTMLFramesCollection2* frames;
long num;
doc->get_frames(&frames); /* THIS IS THE PROBLEM
if (frames == NULL)
///failed
else
{
....
}
In VC6, the get_frames function returns a valid address everytime, whether it is a framesize of 1, or 2 or whatever...
However, when compiled in VS.NET, 'frames' ALWAYS ends up NULL.
What would cause this?
I am using the VS.net Beta 2. Is this a known problem that is fixed in the final release? Is there a solution??
Or is the problem something else entirely?
This was tested and confirmed using both IE5.5 and IE6.
Thanks!

I was just curious how I can change the background color of my dialog box. Any assistance would be appreciated.
Thanks in advance,

Have a look at WM_CTLCOLOR (OnCtlColor if MFC) - you get a chance to return the brush used to paint the background of this and other controls.
|
|
|
|

Overwrite CWnd::OnEraseBkgnd ( for WM_ERASEBKGND message), and paint yourself the background. For example :
BOOL CTestDlg::OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetWindowRect( &rect);
ScreenToClient( rect);
CBrush brh;
brh.CreateSolidBrush( RGB( 0, 0, 255));
pDC->FillRect( rect, &brh);
brh.DeleteObject();
return TRUE;
}
this will make the background for CTestDlg blue.

Thanks everyone for your help. It's people like you that make it all seem possible to distraught newbies like me.

In Prolog, if you are not interested in some variables, you can use "_" to represent it. It means you do not care its returned values or input values. In VC++, do we have some mechanism like Prolog does?
|

In functions, just leave out the variable name
int func ( int n, char ch, long, void* )
{
}

Whats the easiest way to dynamically load HTML into the IWebBrowser2 control ? If I have a CString that holds html text is it possible to load it into a browser control ?
Thanks in advance
|
|
|
|
|
Yes you can . Get the document, and use IHTMLDocument2::write / writeln methods to write raw HTML data into. Or if you want to use IWebBrowser2 interface direcly , use Navigate2 method.

You can also load the page from a resource using the LoadFromResource method. (Assuming you are using CHTMLView) or by using the res protocol (res:/<MODULE_NAME>/<RESOURCE>)

One way i use is to get a pointer to an Element,
usually the BODY element, but you can do the
trick with any other elements (DIVs,SPANs,Ps,etc).
Then use the put_InnerHTML method.
One bug/feature of this trick is that you can
load an HTML file from the disk/Resourse and then
replace the body with a dynamically generated HTML string.
The document will still have the Stylesteets,scripts,METAs
defined in the section and also the attributes
defined in the body.
ex.
- - - - - - - - - - - - - - - - - -

Dear all.
How to get the name of the recently added file to a Particular folder?
In my project i have to find the recently added file name for particular directory.
Presently i am watching the folder continuously and i am catching the event when ever the new file is entered to this folder( for this i am using Franky Braem Filemonitor control.. this is an exelent ATL control,please go through )
But i have to get the file name which is recently added to the folder.
advance thanks.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

Why not look at the time of last modification or time of creation, when you have to display the list of recently modified files.
But, if you have to display it realtime, watching the folder continuously seems to be the only option that you have ... If you need to display only the files that are modified during the lifetime of your application, then monitoring would be the best solution. It is not very expensive because the app is just waiting on an object...

The Win32 API functions to do this are
1. ReadDirectoryChangesW - not supported in 95/98/ME
2. FindFirstChangeNotification and
FindNextChangeNotification functions - works from 95 upwards
There is a C++ example in MSDN under the title
"Monitoring Changes in a Directory or Directory Tree". If you search this in MSDN for the exact string, ie using quotes on both sides, the example is the first result.
I am not very familiar with VB, so I do not know how you can use this info in VB. In C++, I would have a worker thread, that calls a callback function, with the changes as and when they occur.
Hope this helps

I know it's possible to wrap my entire application in an exception handler so that when our code does something it's not supposed to do, I can pop up a dialog saying, "We're crashing, here's a log of the application state."
I've even cut and pasted an example from MSDN, and I'm in the midst of trying to find that again. Can someone point me in the right direction?
