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[^].

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();

Setting timeout on socket connect

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.

CListBox and GetDlgItem Error

Licensed2Code14-Sep-02 8:17

14-Sep-02 8:17

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>

Simulating doubleclick

Jack Handy14-Sep-02 7:47

14-Sep-02 7:47

Currently I'm using

mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

I could easily do the same thing with SendInput() but my question is, is this the right way to simulate a doubleclick?

According to the MSDN the mouse_event function has been superseeded by the SendInput() function so i think it would be best to use that.

What causes a "User breakpoint" to be called?

My program worked fine two minutes ago, but now when i enumerate a list with ACM compressors, i get a "Unhandled exception at 0x77f767cd in MP3.exe: User breakpoint." Why does it do that? I have never had problems with that before. It happens when i open an ACM driver:

acmDriverOpen(&hacm, hadid, 0);

It's opened inside an enumeration function where i get a HACMDRIVERID delivered inside the function so it should be valid. Anyone have some info on "user breakpoints" or know what could be wrong?

Thanks in advance.

Your program got lost probably and jumped randomly somewhere into memory. Maybe a stack was damaged before returning from a function.
