Windows has a feature called Backup. Find it here , and a list of related actions here.

A Universal TCP Socket Class for Non-blocking Server/Clients Single Threaded The function PumpMessages() processes all Windows messages which arrive in the application so the GUI stays responsive although the code runs an endless loop:

// Set Timeout 50 ms
mi_Socket.Listen(0, ms32_Port, 50);

while (...) // This loop runs in the GUI thread
{
PumpMessages(); // process Windows messages

DWORD u32\_Event;
SOCKET  h\_Socket;
// ProcessEvents() returns after 50 ms or after an event was received
DWORD u32\_Error = mi\_Socket.ProcessEvents(&u32\_Event, &h\_Socket, ....);

if (u32\_Error == ERROR\_TIMEOUT)
    continue;

if (u32\_Event & FD\_ACCEPT) { /\* A new client has connected \*/ }
if (u32\_Event & FD\_READ)   { /\* Data has been received \*/ }
if (u32\_Event & FD\_CLOSE)  { /\* A socket has closed \*/ }

if (u32\_Error) { /\* handle error \*/ }

XmlDocument::ImportNode does the job, It states and i quote: "The ImportNode method is the mechanism by which a node or entire node subtree is copied from one XmlDocument to another. The node returned from the call is a copy of the node from the source document, including attribute values, the node name, node type, and all namespace-related attributes such as the prefix, local name, and namespace Uniform Resource Identifier (URI). The source document is not changed. " more from MSDN.. Code from MSDN:

#using <System.Xml.dll>

using namespace System;
using namespace System::IO;
using namespace System::Xml;
int main()
{

//Create the XmlDocument.
XmlDocument^ doc = gcnew XmlDocument;
doc->LoadXml( "<bookstore><book genre='novel' ISBN='1-861001-57-5'><title>Pride And Prejudice</title></book></bookstore>" );

//Create another XmlDocument which holds a list of books.
XmlDocument^ doc2 = gcnew XmlDocument;
doc2->Load( "books.xml" );

//Import the last book node from doc2 into the original document.
XmlNode^ newBook = doc->ImportNode( doc2->DocumentElement->LastChild, true );
doc->DocumentElement->AppendChild( newBook );
Console::WriteLine( "Display the modified XML..." );
doc->Save( Console::Out );

uh huh, I ripped that code from there :cool:

Here you go.

Does this help? If not, more here on splitters.

MSDN says: The following example calls the HH_DISPLAY_TOPIC command to open the help file named Help.chm and display its default topic in the help window named Mainwin. Generally, the help window specified in this command is a standard HTML Help Viewer. MSDN Example

HWND hwnd =
HtmlHelp(
GetDesktopWindow(),
"c:\\Help.chm::/Intro.htm>Mainwin",
HH_DISPLAY_TOPIC,
NULL) ;

#include <windows.h>
#include <stdio.h>
#define BUFFER_SIZE 200

int main()
{
TCHAR infoBuf[BUFFER_SIZE];

// Change accordingly to other path of your machine
TCHAR lpPathName[200] = "c:\\";

// get the current working directory
if(!GetCurrentDirectory(BUFFER_SIZE, infoBuf)) printf("GetCurrentDirectory() failed!\n");

printf("Your current directory is: %s\n", infoBuf); printf("Changing directory...\n");

// set to current working directory
if(!SetCurrentDirectory(lpPathName)) printf("SetCurrentDirectory() failed!\n");

// do some verification...
if(!GetCurrentDirectory(BUFFER_SIZE, infoBuf)) printf("GetCurrentDirectory() failed!\n");

printf("Your current directory is: %s\n", infoBuf);

// get and display the Windows directory.
if(!GetWindowsDirectory(infoBuf, BUFFER_SIZE)) printf("GetWindowsDirectory() failed!\n");

printf("Your Windows directory is: %s\n", infoBuf);

// get and display the system directory.
if(!GetSystemDirectory(infoBuf, BUFFER_SIZE)) printf("GetSystemDirectory() failed!\n");

printf("Your system directory is: %s\n", infoBuf);

return 0;
}

is done like this:

#include <iostream>
using namespace std;

void charray(char test[]) {
strncpy(test,"test",sizeof(test));
}

int main() {
char test[256]={' '};
charray(test);
printf("Text in %s!\n", test);
return 0;
}

What you are likely seeing is a call to MessageBox() before the exception is thrown. To turn that off, you can go into the Project Options and add NO_PROMPT_ON_HRCHECK_FAILURE to the Conditionals list. The exception will then be thrown without any prompting. If you are still using the TComInterface wrapper, the '->' operator validates whether the interface pointer is available or not. If it is not, an ASSERT is thrown. To disable the prompt on that error, you can define NO_PROMPT_ON_ASSERTE_FAILURE in the Project Options. If you implement a try..catch block, it will catch errors normally without messagebox prompt interruptions. (sample try catch)

try {
buf = new char[512];
if( buf == 0 ) throw "Memory allocation failure!";
}
catch( char * str ) {
cout << "Exception raised: " << str << '\n';
}

Change this line:

HRESULT __fastcall GetHTMLItem(ParentIntf *CollectionOrElement, const WideString &name, ItemIntf** ppIntf)

To this:

HRESULT __fastcall GetHTMLItem(TComInterface<ParentIntf> &CollectionOrElement, const WideString &name, ItemIntf** ppIntf)

I hope this Boland C++ Builder 6 code might work..

#include utilcls.h
#include Mshtml.h

{
TVariant vName = name;
TVariant vIndex = 0;
TComInterface disp;

HRESULT hRes = CollectionOrElement->item(vName, vIndex, &disp);
if( SUCCEEDED(hRes) )
hRes = disp->QueryInterface(\_\_uuidof(ItemIntf),(LPVOID\*)ppIntf);
return hRes;

}

void __fastcall TForm1::CppWebBrowser1DocumentComplete (TObject*
Sender, LPDISPATCH pDisp, TVariant *URL)
{
if( CppWebBrowser->Document )
{
TComInterface HTMLDoc;
if(SUCCEEDED(CppWebBrowser->Document->QueryInterface(
IID_IHTMLDocument2,(LPVOID*)&HTMLDoc) ) )
{
TComInterface forms;
if( SUCCEEDED(HTMLDoc->get_forms(&forms)) )
{
TComInterface form;
if( SUCCEEDED(GetHTMLItem(forms, "loginform", &form)) )
{
TComInterface userid;
TComInterface password;

			GetHTMLItem(form, "userid", &userid);
			GetHTMLItem(form, "password", &password);

			if( userid )
			userid->put\_value(WideString("username"));

			if( password )
			password->put\_value(WideString("password"));
			}
		}
	}
}

}

I hope this Boland C++ Builder 6 code might work too..

Yes QtGui on Linux. I's so easy to learn , like so:

#include int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel label("Hello, world!");
label.show();
return app.exec();
}
