What do you mean by fixed? Perhaps you can try posting some code sample on that.

Thanks alot for yr help.. but i still have some misunderstanding.. my program.. a simple server n client program.

For my client program.. the logged in ip. address is set in a uility.cpp (which is one of the header file..)

i was hoping to check it to more versitaile.. so that i can change the ip when the main dialog is running..

but it seem that the moment the program compile it read the uility first hence i can exe it.

is it possible to like by pass it then let call it back..

the ip.. setting is in uility.cpp and my simple edit. box is in dialog.cpp

anyhelp is greatly appraised

If that ip address is stored as a member variable of some class in utility.cpp, then you can just create a member function to modify it. If it is a global variable, just make sure it is declared with extern in the file that you want to access it. Again, post some code for the ip address part in utility.cpp if possible.

// utility.cpp -- contains stuff used by more than one thread
#include <stdafx.h>
#include "utility.h"

CString g_strServerName;
//The IP address in the following line is to be changed to that of the machine
//in which the Server is installed.
CString g_strServerIP = "192.0.3.109";volatile UINT g_nPort = 1500;
BOOL g_bConnected = FALSE;
BOOL g_bServerClosed = TRUE;
char *g_cRequest;
CBlockingSocket g_sClient;
CEvent g_eventKill;

that line already set is as that ip.. i wanna declare a variable in the main dialog.cpp then throw the value over.. is it possible.. thank alot

Ok since g_strServerIP is a global and you want to access it in dialog.cpp, then you need to put this line there:

extern CString g_strServerIP;

Now in your dialog.cpp you can access it to change the value:

// dialog.cpp
CString sNewIP = "255.255.255.255"
g_strServerIP = sNewIP;

thanks.. i try it and compile.. no error..
i add in
#include "stdafx.h"
#include "ChatClient.h"
#include "ChatClientDlg.h"
#include "utility.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;

extern CString g_strServerIP;#endif

and at a button..
void CChatClientDlg::Onipcon()
{
CString str;
m_IpCon.GetWindowText(str);
g_strServerIP=str;

}

it should work right!

but problem the moment the program started it retrive the ip from the uility and if there no fix ip.. the program freeze up although it can compile but i cant connect to the server..

Don't put it inside the #ifdef tags.

Check your connect function. Run a debug and see how or where it freezed.

ACTUALLY IT DIDNT FREEZE UP..the whole program still run but.. but when i key in my ip it didnt work..
i tink it because the compiler run though the uility first hence .. it "jam" the program because it cant find any ip address.. cos at the point of start it is a unknow number

Hello

You can use GetHtmlDocument() method to get IDispatch interface of HTML document object. Then you can query interfaces of your interest: IHTMLDocument2, IHTMLDocument3. With these interface you can access entire HTML document. Look at MSDN. All these MSHTML interfaces are documented pretty well.

You can get a handle to an IHTMLElement and then you'll be able to insert code in an html document position[^] or to replace the whole document[^]

Invalid command line arguments?

Just wanted to comfirm, is it true that characters like '>' or '<' can't be passed as command line arguments? I have a main function to take in parameters. However, it seems that characters like '>', '<' can't be passed in. e.g.

abc.exe 9000 // 9000 captured in main
abc.exe >9000 // Nothing captured in main

me think that < or > are used as indirection for the command parser ( dos ).

for example,

dir > qq.txt

will put the result of the dir command in the qq.txt file.

if you want to put < or > in a parameter, you could enclose it in "

Instead of arguments use the command line itself and parse it using your own code.
GetCommandLine provides you with the raw command line.

You can still call Win32 API's!!! Like GetCommandLine.

And, BTW you *can* create a "windows" even in a commandline program, JFYI!
