ReportDocument DataSource [modified]

It's all about polymorphism!

A Googly search on "C++ virtual functions" yields billions of articles on the subject (ok, maybe
not that many).

For example: Polymorphic and Virtual Functions in C++[^]

Have you looked at the scores of .NET Database Articles here on CodeProject?

Hello Sir
I am very happy because for the first time I print in Visual c++ NET with report. This what I do:
SqlConnection^ cprl = gcnew SqlConnection();
cprl->ConnectionString = "Persist Security Info=False;Integrated Security=SSPI;database=payroll05;server=sem;Trusted_Connection=Yes;" ;
cprl->Open();
Ds_report^ data = gcnew Ds_report();
SqlDataAdapter^ adapt = gcnew SqlDataAdapter();
SqlCommand^ Cmd = gcnew SqlCommand();
Cmd->CommandText = "select* from ficag21";
Cmd->CommandType = CommandType::Text;
Cmd->Connection = cprl;

adapt->SelectCommand::set(Cmd) ;
adapt->Fill(data,"ficag21");

rptsearchsig->SetDataSource(data);
rptsearchsig->Load("C:\\Documents and Settings\\miki\\Mes documents\\Visual Studio 2005\\Projects\\payroll\\payroll\\rp_signal.rpt");
rptsearchsig->PrintToPrinter(1,true,0,65500);

It's very simple but I take three days to do it.

I will send you my article to explain well for helping others that are in the same difficult.

Thanks to all halp me

Here's an example using WMI to get the MAC addresses for all the "Ethernet 802.3" adapters on
the system:

#using <System.Management.dll>
using namespace System::Management;
...
ManagementObjectSearcher searcher("SELECT Name,MACAddress FROM Win32_NetworkAdapter WHERE AdapterType = 'Ethernet 802.3'"); 
ManagementObjectCollection::ManagementObjectEnumerator^ enumerator = searcher.Get()->GetEnumerator();
while (enumerator->MoveNext())
{
   Console::WriteLine(enumerator->Current["Name"]);
   Console::WriteLine("   {0}", enumerator->Current["MACAddress"]);
}

which probably means you should "Add a reference" to System.Management.dll to your project

Which language are you coding in? This forum is for dot net cpp stuff. Whatever the case you'll probably need to provide some more info or post some small sections of your code. I've been doing some UDP stuff the last few months so I might be able to help

I would suggest that you post this in the Visual C++ forum and enclose the code inside

tags, or click the "Ignore HTML tags in this message" check box so that its easier to read

I'm not sure I'm understanding your problem, but do you have your recvfrom() call in a loop? If you don't, you'll just get one datagram and your thread function will continue to whatever's next.

Using Static Libraries in Managed C++

We have some static libraries created long time back say 10/15 yrs back.
We have build all the libraries in visual studio 2005.
But when we create a managed C++ application and try to use classes from the static libraries , the application just crashes with no traces as to why did the application crash.
Application crashes in dbgheap.c.
the static libraries which we use have reference to ATL as well.

With the same set of project settings if a create MFC application in Visual studio 2005 everything seems to be working fine.

Questions:
1. Is it possible for managed C++ application to use static libraries , if yes then what is to be done.
2.What are the options use a static library in managed code.

I have not used static linking for years. If it turns out there is some problem with that you might consider turning the libraries into DLLs. We have several projects using old code from DLL libraries that work just fine.

Ah, I've been reading this forum for months, waiting for a question I could actually answer. Big Grin | :-D

At least, I hope I can answer it. If, when you say "managed C++", you actually mean C++/CLI, then the answer is yes. I have written a couple of test applications that statically link one of my native-code libraries to a C++/CLI application that uses managed code. I had some trouble getting static variables in the library to initialize properly, which caused various crashes. I was an MSDN subscriber at the time, and I got a solution from the MSDN-only forums in a matter of days -- I was impressed.

If you're trying to link to a C++/CLI application and you have static variables in your library, I'd be happy to send you the workaround. If you're using the old Managed C++ or don't have any static variables in your library, then I can't help you, sorry.

PostMessage - WTF?!

ok, so I am using the function PostMessage(msg, wParam, lParam) TWICE in succession:

if (m_pSelectionDlg->GetSafeHwnd()) {
	// #1
	m_pSelectionDlg->PostMessage(WM_ADDENTITY,wParam, lParam);

	//NEW!!
	static CWnd *pWnd;
	if ( (pWnd = FindWindow("MyAppClass",0)) != NULL)
		// #2
		pWnd->PostMessage(WM_ADDENTITY,wParam,lParam);
}

for the first call (#1), wParam = 1 and lParam = 0.

for the second call (#2), I step inside the PostMessage() function and wParam = 0 and lParam = 0. Why? Confused | :confused:
