Hello,
look this,

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

Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

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 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.

Hi,
I am trying to build a application using MC++, but what I found out is that each time when I am runing the application in debug mode (have not tried release yet), it always takes more than 5 seconds to start the applicaiton. First, I thought there was something wrong with my code, but when I tried to build some sample codes, which I downloaded from web, it was the same. It took more then 5 seconds to start the program. I am wondering if this is the way it is supposed to be or there is something that I need to setup with my VS.Net, which I didn't...Can anyone give me some suggestions about what is wrong and what I should do with it. Thanks alot

Whats your system Configuration?
and Check below things in your System.
1.Clean Your temp files from the system
2.Check the Virtual memory you set, if it is less than some 500MB then increase it to 1000 MB

How about:
char *input = malloc(sizeof(char) * 4294967296);
BTW:
Unless your computer has 4 gigabytes of RAM, you'll really need to redesign your data input code

Try int x = Convert::ToInt32(str); or int x = Convert::ToInt16(str);
Convert has several conversions available.

ok this is annoying...the following line is killing vs...(hate this)
containerListViewItem2->Tag = __box(0);
ive seen this problem before, its like when you add components to c++ .net...if it makes this __box command it kills the visualizer and only way to fix is to continiously delete that line from form1.h and offcurce vs.net re adds it
