#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!

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.

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
abc.exe >9000

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!

AfxMessageBox("Hello Message" ) is appear a message box in the screen right? But I just want a message to print out on the screen not a message box

Try to use TextOut() function with reference to window rect coordinates from GetWindowRect() ...
I did not try it out ...but this should work

I have an external application that launches my application. I have a global variable that determines whether my app was launched via the other app or just by opening the executable. If launched via the other application, two processes or instances gets created and the global variable is set to 1. The first instance will be created but the window frame will not be shown. The other instance will display the window. One instance has the global value initialized to 0 while the other one has it set to 1. I need to block the instance that has global variable = 0 and let the other one run. Once that thread completes, I want the other thread (I believe it’s the main thread) to continue running. I tried using a mutex around my code but it still seems to be doing context-switching. How can I put a hold on thread1? I’ve tried using events but no such luck. This is what I have. Thanks!
<pre>
InitInstance()
{
mutex = ::CreateMutex(NULL, FALSE, “X”);
if(mutex==NULL)
{
AfxMessageBox("Error: Problem with creating the mutex");
return FALSE;
}
else {
WaitForSingleObject(mutex, INFINITE);
if (!bGlobalVariable)
{
OneInstance = ::CreateMutex(NULL, FALSE, “instance”);
DWORD dwMutexErr = GetLastError();
if (dwMutexErr == ERROR_ALREADY_EXISTS)
return FALSE;
}
ReleaseMutex(mutex);
}
if (!GlobalVariable)
//show window
return TRUE;
}
</pre>

I'm looking for ideas. I have an embedded application that must respond to a changing system environment. A good analogy would be a loosely networked set of PCs. My application (SDI, but heavy on dialogs) monitors this system and allows the user to program it. If everything is stable, then I have no problems. The issues start when I have a 4 node system, and the 2nd node drops out. Because of my dialog layers, I could easily be 4 layers into dialogs when this occurs.
Is there any way to cleanly "unwind" from my dialog stack in a programmatic fashion?
