i use DirectX 6.1
following is a piece of code to be compiled
//inside a function
IDirectDraw*pdd;
HRESULT hr;
hr=::DirectDrawCreate(0,&pdd,0);
IDirectDraw4*ppd4;
hr=pdd->QueryInterface(IID_IDirectDraw4,(void**)&ppd4);
pdd->Release();
in win32 App, the code is compiled no problem.
but once in MFC, i got compile error:
*****************************************************
error LNK2001: unresolved external symbol _IID_IDirectDraw4
*****************************************************
to solve the error, i try all but none of them working,
following is includes and libs in CPP file:
#define INITGUID
#include <objbase.h>
#include <initguid.h>
#include <stdio.h>
#include <stdarg.h>
#include <windows.h>
#include <mmsystem.h>
#include <ddraw.h>
#pragma comment(lib,"ddraw.lib")
#pragma comment(lib,"ddraw.lib")
#pragma comment(lib,"winmm.lib")
#pragma comment(lib,"kernel32.lib")
#pragma comment(lib,"user32.lib")
#pragma comment(lib,"gdi32.lib")
#pragma comment(lib,"winspool.lib")
#pragma comment(lib,"comdlg32.lib")
#pragma comment(lib,"advapi32.lib")
#pragma comment(lib,"shell32.lib")
#pragma comment(lib,"ole32.lib")
#pragma comment(lib,"oleaut32.lib")
#pragma comment(lib,"uuid.lib")
#pragma comment(lib,"odbc32.lib")
#pragma comment(lib,"odbccp32.lib")
#pragma comment(lib,"dxguid.lib")
//-------------------------
where is IID_IDirectDraw4 defined?
why no problem in win32, but trouble in MFC?
thx for any help

Consider downloading the latest Platform SDK, or the DirectX SDK (microsoft.com/directx). Either case, this should be at least 200MB a download.
IDirectDraw4 is an interface which appeared in DirectX 7.

nothing about sdk.
it can be compiled in win32 app.

Hi,
I have a CRichEditView derived class. I want to handle when the user selects text with the mouse by pressing the left button. This works fine but when the mouse pointer is dragged belov or over the window the selections stops, which means that the user only can select text that is visible in the window. So I want to scroll when this happens.
Does this make sense?
Regards

use SetCapture() on LButton down
and ReleaseCapture() on LButton up

Thanks that seems to do the trick.
Do you know how to handle ctrl-key input?
I can get when the user press ctrl and when a user press another one. Do I need to keep track if the ctrl is pressed or is there a predefined way to do that, multiple key input?
Cheers

use GetKeyboardState() in key down and char down messages.

Hi,

I don't know. I just answered his question..
I know it is possible though. You can read and write ethernet packets without any special voodoo. And ICMP packets are quite easy to construct as well, so I do know that it is not impossible.

I know that the answer is yes too but , if i really dont know how to do it, then no point in replying the question.

Thanks Mr.Prakash.
But, the source code you specified is using socket commands
like gethostbyname,WSAStartup...

Hi,
I am writing a P2P chat application. It allows two persons to communicate with each other over the internet using their IP addresses. The application works fine when both users are directly connected to the internet. but if one user is behind a firewall or proxy, the application does not connect. I understand that I have to bypass the proxy using SOCKS protocol. I want to ask is there some class or other method, that does this for me, that is, any implementation of the SOCKS protocol. I am using Visual C++ 6.0.

hy, i have a virtual function in a class. i must go sure, that every class who is inherited from this class overwrites this function, otherwise a warning shoud occur at runtime, or something like that. is this possible??
thanx andreas

|
|
|
|
in the base class make the functino pure virtual
like
virtual void somefunction() = 0; //pure virtual function.
this ensures that the derived class has to override/implement the method.
|
|
|
|
|
yes, but i need a technique, who workes also when i derive a class from a derived class and so on!
is there any trick?
|
|
|
|
|
Please do read about pure virtual function.
|
|
|
|
|
yes, but what, if i make a pure virtual function (abstract class) then derive a class from it, and implement this function. now i derive a class from this class, and forget to overwritte this function, how will i know?

It will cause a compile error.
