Downloading a web page

[SteveCRM]

how could I download a web page? I've never used winsock before and I thought this might be a good way to dive in

You can send the GET command to the webserver

GET /index.html

This will return the source to the HTML file.

Maybe you can use this API:

URLDownloadToFile
HRESULT URLDownloadToFile(
LPUNKNOWN pCaller,
LPCSTR szURL,
LPCSTR szFileName,
DWORD dwReserved,
LPBINDSTATUSCALLBACK lpfnCB
);

Downloads bits from the Internet and saves them to a file. The client can choose to be notified of progress through a notification callback.

pCaller
Address of the controllingIUnknown interface of the calling ActiveX component (if the caller is an ActiveX component). If the calling application is not an ActiveX component, this value can be set to NULL. Otherwise, the caller is a COM object that is contained in another component (such as an ActiveX control within the context of an HTML page). This parameter represents the outermost IUnknown of the calling component. The function attempts the download within the context of the ActiveX client framework and allows the caller's container to receive callbacks on the progress of the download.
szURL
String containing the URL to be downloaded. Cannot be NULL.
szFileName
String containing the name of the file to create for bits that come from the download.
dwReserved
Reserved for future use. Must be zero.
lpfnCB
Address of the caller's IBindStatusCallback interface. URLDownloadToFile calls this interface's IBindStatusCallback::OnProgress method on a connection activity, including the arrival of data. IBindStatusCallback::OnDataAvailable is never called. Implementing IBindStatusCallback::OnProgress allows a caller to implement a user interface or other progress monitoring functionality. It also allows the download operation to be canceled by returning E_ABORT from the IBindStatusCallback::OnProgress call. Can be NULL.

to use winsock, do you just have to include windows.h? or something else?

[SteveCRM]

I think for this it's just windows.h

for something like a chat you'd use soemthing like winsock.h

i think....

[sail3005]

ahhh...i see

thanks steve

game.obj : error LNK2001: unresolved external symbol _URLDownloadToFileA@20
Debug/WebRover.exe : fatal error LNK1120: 1 unresolved externals

I get it here

char URL[150];
GetWindowText(SearchBox, URL, 150);		
URLDownloadToFile(NULL, URL, "url.txt", 0, NULL);

[Vlatko]

You need to include a library(urlmon.lib i think).

[SteveCRM]

thats it! Thanks vlatko!
