I haven't had a re-occurrence since I simply initialised my structs, but thanks for pointing that out.

Hi,
I am working on an application, which calls a WPF page in MFC exe and loads it too, but the backgound for the WPF is coming black.
here is code snippet
Declaration
using namespace System;
using namespace System::Windows;
using namespace System::Windows::Controls;
using namespace System::Windows::Media;
ref class Globals
{
public:
static System::Windows::Interop::HwndSource^ gHwndSource;
static WpfApplication1::Window1^ gwcContainer;
};
i have added in oninitdialog,
System::Windows::Interop::HwndSourceParameters^ sourceParams = gcnew System::Windows::Interop::HwndSourceParameters("MyWindowName");
sourceParams->PositionX = 20;
sourceParams->PositionY = 30;
sourceParams->ParentWindow = System::IntPtr(this->GetSafeHwnd());
sourceParams->WindowStyle = WS_VISIBLE | WS_CHILD;
System::Windows::Interop::HwndSource^ source = gcnew System::Windows::Interop::HwndSource(*sourceParams);
source->SizeToContent = System::Windows::SizeToContent::WidthAndHeight;
Globals::gwcContainer = gcnew WpfApplication1::Window1();
FrameworkElement^ myPage = Globals::gwcContainer;
source->RootVisual = myPage;
I dont want the black color around.
Any help is highly appriciated.
Thanks&Regards,
KDevloper

I got 1231 error value when using the code below.
1231: The network location cannot be reached. For information about network troubleshooting, see Windows Help.
my lan and internet is working fine.
then where is actually the problem residing.
HANDLE hIcmpFile;
unsigned long ipaddr = INADDR_NONE;
DWORD dwRetVal = 0;
char SendData[] = "Data Buffer";
LPVOID ReplyBuffer = NULL;
DWORD ReplySize = 0;
ipaddr = inet_addr((const char*)m_sAddress);
ReplySize = sizeof(ICMP_ECHO_REPLY) + sizeof(SendData) +1;
ReplyBuffer = (VOID*)malloc(ReplySize);
hIcmpFile = IcmpCreateFile();
if (hIcmpFile == INVALID_HANDLE_VALUE)
{
return -1;
}
dwRetVal = IcmpSendEcho(hIcmpFile, ipaddr, SendData, sizeof(SendData) + sizeof(ICMP_ECHO_REPLY), NULL, ReplyBuffer, ReplySize, 500);
if(dwRetVal != 0)
{
PICMP_ECHO_REPLY pEchoReply = (PICMP_ECHO_REPLY)ReplyBuffer;
struct in_addr ReplyAddr;
ReplyAddr.S_un.S_addr = pEchoReply->Address;
m_sMessage.Format(_T("Received from %s Status = %ld RoundTripTime = %ld"), inet_ntoa(ReplyAddr), pEchoReply->Status, pEchoReply->RoundTripTime);
return 0;
}

If you want to use ping from your application, have a look at boost::asio. Boost have a ping example program that you may be able to adopt. Note that your application requires administrative privileges on Vista to create ICMP packets.

How to plug/unplug USB serial port problematically?
I am facing some strange issue with my USB serial port.

You cannot do that from user mode. You must ask the driver for that functionality if it supports it at all, which I doubt when it comes to serial port drivers for USB.

Perhaps you can elaborate on what the "strange issue" is all about.
It's quite possible that there is another solution than resetting the port/device.
What have you done so far and what problems are you facing that you want to solve by resetting the port?

Hi All,
I have a basic question , i have a dialog based application and in the App class we create an object for the dialog class and do DoModal()in InitInstance() of the App class ..
Can anyone tell me when Run the Application How the InitInstance will get called or the other of calls made which calls the App classes InitInstance()
Thanks,
Hari

There's a very easy way to check that: put a breakpoint in the function and start your debugger. Once the breakpoint is hit, take a look at the callstack.

I tried it and it says AfxWinMain() can anybody explain in detail and thks for the quick reply.

See here[^]. It's an old article but I think it will already give you valuable information.

I realize now why he's so busy these days....
Most problems in the world that some people are waiting for God to solve will remain due to all his calls to InitInstance()....
Revolutionary - I've never thought of it that way before!

However, as balance, there are all the missed problems due to the lack of God's intervention...

Hi All,
Need car motion simulator supporting directional control with ramp up/down facilities.
Do appreciate a plain text explanation for subject related physics algorithms.
Thanks.
|
|
|
|
|
What is your exact question ? Are you looking for a physics engine ? If yes, take a look at Newton Physics Engine[^]
|
|
|
|
|
I'm not looking for a physics engine, what I'm looking for is simple car shape that can move forward and backward along with left/right turn functionality and as well as ramp climbing option.
It is highly appreciated if the above mentioned motions formulas can be explained.

Well, they actually are explained: in physics books.

I want to write a class that creates its own device context (dc) and provide function to draw line between two points. This class should provide function CopyDC(srcDC, destDC); This class should be an independent class (should not be derived from any other class) so that i could use this class in any other project later.
i have no idea how to do this in MFC dialogs. Please help me....

If you need a full graph (not only a simple line), you can take a look at my signature. I developped such a charting control and it could be useful for you.
