How can I convert a String* data to char*? Is it possible to do Type convertion between managed type and unmanaged type. Is there any article which gives an explanation on this type conversion?

Please help.

Thanks very much. But now I get another error when I include the namespace System::Runtime::InteropServices.

error C2872: 'FILETIME' : ambiguous symbol
could be 'D:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\PlatformSDK\Include\WinDef.h(354) : _FILETIME FILETIME'
or 'stdafx.cpp(0) : System::Runtime::InteropServices::FILETIME'.

Kindly help.

Now its fine. I changed my function call to
IntPtr ip=System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi("hello World"),
instead of including the namespace in the using namespace stmt and then calling the function as
IntPtr ip=Marshal::StringToHGlobalAnsi("Hello World").

Thanks for the help

Calling an MFC dll

I have defined a managed C++ project to call into an unmanaged MFC project. The MFC project builds successfully. However, the build of the managed project fails because the linker cannot resolve the external symbols for the methods defined in the unmanaged class. Attached is the class definition for the managed class:

public __gc class MTracker
{
public:
MTracker(Control* pControl,Control* cControl)
{
m_CTracker = new CComTrackerApp();
IntPtr pPtr = pControl->Handle;
IntPtr cPtr = cControl->Handle;
HWND pHwnd = (HWND)pPtr.ToPointer();
HWND cHwnd = (HWND)cPtr.ToPointer();
m_CTracker->Create(pHwnd,cHwnd);
}
protected:
void Dispose(bool b)
{
MTracker::Dispose(b);

if (m_CTracker != NULL)
{
delete m_CTracker;
m_CTracker = NULL;
}
}
private:
CComTrackerApp* m_CTracker;
};

The CCOMTrackerAPP class is defined in the MFC project. The linker cannot resolve the addresses for CComTracker::CComTracker() or CComTracker::Create(HWND pHwnd,HWND cHwnd). Any suggestions would be appreciated.

Hi friends..

I have downloaded latest swfsource from www.sourceforge.com

In this swfsource two files : Xmlcompiler.h and XmlCompiler.cpp, are there but no source code is available for these files.

I think these files might be related with parsing Xml data, as this will help me a lot because i am also working on parsing Xml for use in swfsource.

Can somebody guide me regarding the functionality of these files and send me the code for these files ?

Thanks in advance.

Hi there,

I want to show a 3D Cube on a panel of a form using C++.Net. But I don't have any idea how to access the DX9 from C++.net and how to draw on a panel. I need a tutorial on C++.Net to use DirectX9 and D3D.

Hi Everybody,

I am working on open swfsource in VC++ .NET platform..
and in my application i want to parse XML using C++

Can anybody suggest me the way to parse XML data through C++ code?

And, please suggest me if there are any in-built C++ libraries available for parsing XML(preferably SAX) or if in-built libraries are not there, then which third party parser should i use for parsing XML(preferably SAX) data through C++?

Note: Code examples and links are welcome.

Thanks in advance.
