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 />
}<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

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?

ASSERT(::IsWindow(m_hWnd));
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.

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

I've already invoked the DoModal() in InitInstance() part of the application. And if I do it again, it would create another dialog which I dont' want. Anyother ideas???
Thanks...

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?
-Jack
If things are as bad as they can be, you can be sure there'll be a brighter tomarrow.

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.

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.

Hi dear,
How can I split a MPEG file into two or several small files or merge two or several MPEG files to one file?
What about DAT file?
Thank you.

I know there is a program which will patch it for VS6, but has one been released for .NET?
|

Why bother? From a command prompt you can yourself start MSDev.exe in low priority. Just type "start /?" and there you go.
|
|
|
|

Maybe he just want the compiler/linker etc to run at low priority, but the IDE should remain as responsive as possible...

newbie beware,
how could i convert this CString for an encryp routine?
CString tm;
tm = "Hello";
i've tried this, and everything else i could think of:
LPTSTR lpsz = new TCHAR[tm.GetLength()+1];
_tcscpy(lpsz, tm);
TCHAR HelloCrypt[] = lpsz;
i get, "can't convert char* too char[]"
any helps really appreciated.

You can't assign a pointer to an array.
Should be:
LPTSTR HelloCrypt = lpsz;
TCHAR HelloCrypt[] = "Hello" is possible, because it's constant known at compile time.
It's not VB, at runtime you must create arrays of unknown size using new.
