You're blowing things way out of proportion. It doesn't use "all" your memory. Each executable image will be larger, however that is preferable to having to debug screwy problems caused by different DLL versions, which will appear to be your fault because, hey, your program is crashing.

.NET framework is not needed. You need to distribute MFC7 dll files with your app.
See informations about redistributable files in MSDN.

Yeah, thanx. Looked around, read some MSDN help that comes with VS.NET... Well redistributing MFC7 is better than the whole .NET framework, although it takes like 4Mb Frown | :(

MFC libraries have nothing in common with .NET Framework except that MFC7 is part of VS.NET studio. MFC is classic unmanaged C++ library. .NET is from another world.

I have not used VC7 yet. If the .NET framework is not required for programs written with VC7, then what is .NET framework for?

I got 2 different len from string !!!

You can write programs of two kinds using VC++ 7, unmanaged and managed. Unmanaged programs are using WIN32 API and optionally some libraries like MFC or ATL, nothing from .NET, it's the same programming as in previous versions with new IDE and some new features in libraries and compiler. Managed ones are interfacing with .NET framework using MS specific language extensions. .NET framework is an environment very similar to Java with bytecode(called MSIL here), garbage collector, objects and interfaces, rich libraries, see this[^].

Re: I got 2 different len from string !!!

Hello there,
It's my string that i added to Rich edit box:

Ali
Hadi
Asghar

I wrote them by my own function AddText:

AddText(m_Rich, "Ali\nHadi\nAsghar");

The problem is when i get the len, i got differet results in different OS ...
As i can remember, the result was same in Win98 and WinXP
But len was different in Win2000 OMG | :OMG:

I think the problem in for Enter character !
So, how can i get real len in Win2000 ???

I count 3+1+4+1+6 = 15
But the enter and lf would quite possible make 16 || 17
If it's a CString could you not perform a simple Replace on the text before input eg

m_Rich.Replace("\r","");

or use

m_Rich.TrimRight();

Does anyone know how I can set a timeout value for the connect() method of a socket? If it can't connect within about 200ms then I know that it never will.

At the moment the connect is waiting for about 5-10 seconds before it returns.

My code below:

<br />
target.sin_family = AF_INET;<br />
target.sin_addr.s_addr = *(long *)(host->h_addr);<br />
target.sin_port = htons(port);<br />
s=socket(AF_INET,SOCK_STREAM,0);<br />
<br />
if (s<0) exit(printf("Error creating socket.\n"));<br />
if (!connect(s,(struct sockaddr *)&target, sizeof(target)))<br />
{<br />
   // ....... do my thing here ....<br />
}<br />
if (closesocket(s)) exit(printf("error closing socket.\n"));<br />
<br />

I think you can use Winsock's "select" statement. Take a look at that along with the TIMEVAL structure.

Oh yeah, that only works on Winsock 2.0

Microsoft Web Browser ActiveX control

Using Visual C++.NET, I want to insert a IWebBrowser2 control. I have created a class with the "Add Class" wizard choosing "MFC Class From ActiveX Control". It worked fine and the class was added.

I then add 2 controls in my dialog. How do I bind them to variables of the class I added. When right-clicking on the control, the "Add Variable" item is disabled from the context menu, and the "Add Class" don't show the ActiveX class from the drop-down.

How do I do it? It was so easy in Visual C++ 6.0, but now it seems very difficult.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

As i recall, there's a utility that comes with CR that will figure it out for you, based on what features you use. If nothing else, the list should be in one of the help files also.

Hi guys,

I'm getting an assert failure from the following code.

//This is the class which holds the CListBox

CTestDlg::DoDisplay()
{
CListBox *box = (CListBox*)GetDlgItem(IDC_LIST);
//the above line throws an ASSERT
box->InsertString(-1, "It's Good");
}

And.....

//Class which generates the data to be added to the list
CDisplay::Foo()
{
CTestDlg dlg;
dlg.DoDisplay()
}

Assertion Error exactly is:
{ ASSERT(::IsWindow(m_hWnd)); return (int)::SendMessage(m_hWnd, LB_INSERTSTRING, nIndex, (LPARAM)lpszItem); }

And the I've already tried this with modal and modelss dlgs and nothing successful. And yes, the listbox is initialized and is visible in the program. In a nutshell, the DoDisplay() works (adds data to the listbox) inside the class of its own and doesn't when it's invoked outside of its owner class. Can you guys help me? Smile | :)

This test is failing because the dialog window isn't created (m_hWnd is NULL) until you call DoModal().

Call DoModal() to create the dialog, then in OnInitDialog() do whatever control setup is necessary.

Hi Mike,

The Dialog is already running and in there I got the List Box.
When I press a button, it processes data from one class and sending it to the dialog class.

I've already called the DoModal() in the beginning of the application part of th InitInstance() function.

This is how it's.

CTestDlg::DoDisplay(CString sString)
{
CListBox *box = (CListBox*)GetDlgItem(IDC_LIST);
box->InsertString(-1, sString);
}

and when I press a button named "Register" from the dialog (from CTestDlg class), it calls up the following function......

CDisplay::DoRegister()
{
CTestDlg pDlg;
CString sString = "I don't know what to do";
pDlg.DoDisplay(sString);
}

The assert is thrown at the line "CListBox *box = (CListBox*)GetDlgItem(IDC_LIST);" saying IsWindow()==mHandle == NULL.

Since I've already called up the DoModal() at the beginning, I don't see why I've to call it again, and calling it again will create another dialog.

Your help is appreciated.
Jey

Fill the dialog with data in WM_ONINITDIALOG message handler and use it this way:
<pre>
CDisplay::Foo()
{
CTestDlg dlg;
dlg.DoModal()
}
</pre>
