When i include winsock2.h i get a ton of compile errors... - C / C++ / MFC Discussion Boards

In the past, many libraries and samples are simulating VC interface. I'm wondering if there's the same stuff for VS.NET interface ?

I am trying to print the contexts of a CDialog that contains several ActiveX controls. I am looking for a function that I can send a pointer to the CDialog and it will prompt the user for the Printer to use. It would be helpful if the function would take into account Portrait of Lansscape. Any help would be appreciated.

I need any ideas about http requests catching, not only IE but also Netscape and Opera.
I think "AD Muncher" is very cool, it can catch all HTTP requests. FAQ about AD Muncher

Hi,
This will sound very basic and silly!!!
but can someone help me out with finding out how to go about
doing a substr() in C++;

Thanks,
Brgds,
John Cry | :((

doing a substr() in C++;

You use CString.Mid() (this requires MFC), or
you use std::string.substr() (this is standardized and portable), or
us use strstr(), the plain old C-Library function.

Its up to you.

if i include winsock2.h in my program i get 64 errors and 11 warning and i don't know why. i've added the Ws2_32.lib to external dependencies.

here are the errors:

thank you

I want to somehow make my "About" box able to automatically write out the version of my program so I don't have to update it each time I make a new version.

How can this be done?

Something else

I guess u should follow

AfxGetResourceHandle then FindResource with lpType RT_VERSION then LoadResource then LoadString
Hope this help!

The goal of Computer Science is to build something that will last at least until we've finished building it. - Unknown

HRSRC hVersionSrc = FindResource(NULL, (LPCSTR) VS_VERSION_INFO, RT_VERSION);
	HGLOBAL hVersion = LoadResource(NULL, hVersionSrc);
	void* pvVersion = LockResource (hVersion);
	VS_FIXEDFILEINFO * pFfi;
	UINT cbVerInfo;
	VerQueryValue(pvVersion,"\\", (void **) &pFfi, &cbVerInfo);

Thank you all very much for the help Smile | :)

My "About" box is now automatically updated with the correct version number.

Something funny

Is there any way I can create a a CIPAddressCtrl with a drop down history like a combo box? Or, a CComboBox control whose edit box acts like a CIPAddressCtrl?

Hi!

I was implementing the On-screen keyboard application that comes with Windows. I have two queries regarding this:

1. I have made my app 'always on top', but the problem is setting focus to the application just below this one. I am aware that SetFocus is useless in this case. I want to find a way to this using GetNextWindow

2. Let's assume notepad is going to be receiving keystrokes via this on-screen keyboard app. Can anyone send me code to this. I have tried something like:

DWORD dwProcessID;
::GetWindowThreadProcessId(hForeground,&dwProcessID);

::PostThreadMessage(dwProcessID, WM_KEYDOWN, 65, 1);
::PostThreadMessage(dwProcessID,WM_CHAR, 65,1);
::PostThreadMessage(dwProcessID, WM_KEYUP, 65,1);

But this doesnt help.

Any help will be greatly appreciated.
Thanks for your time

Richard

Better to use FindWindow or FindWindowEx and SendMessage or PostMessage

For Win32 applications, not MFC Smile | :)

thanks all!

The majority of the articles on CodeProject for sockets programming use the Win32 Sockets functions rather than hte MFC CSocket & CAsyncSocket, its only the user-interface that is built in MFC usually. So you can grab most of the socks code and build your win32 app around what you can pick up.

can't seem to find it...

thanks.
