FPS is frame per second.
Sorry! m_FPS is customized strcut as below:
ref struct sFPS
{
sFPS()
{
Init();
}
void Init()
{
FrameCnt=0;
TimeElapsed=0;
dFPS=0;
}
void CalculateFPS()
{
dFPS = (Double)FrameCnt / (TimeElapsed/1000.0f);
}
DWORD FrameCnt;
DWORD TimeElapsed;
Double dFPS;
};
In MFC project, I can use the CWinApp::Idle to count the frame number for FPS. But in CLR project. Application::Idle is not always called(must have some windows messages be triggerred), so I cannot use it to calculate FPS if the mouse does not focus on the winform. I want to find a event that will be called at any time.

Right. But I asked "FPS of what? What frames?"
Video?

A Timer[^] maybe?

Not for video. I use for DirectX.

I guess I'm missing what you're trying to do.
It seems to me a FPS calculation should be done when each frame
(or multiple of frames) is rendered, not during an idle event,
unless the idle event is the only time a new frame is rendered.

Hi all,
Is there any function or API, which give me the name of opened .exe or file name and path(by right click->Open or by double clicking) from any drive or desktop.
thanks

I define a class MyObject. I want to use PropertyGrid to browse and modify the attributes of myObject (MyObject object).
Can I reach this goal? If the answer is "Yes". Could sombody tell me how to do?
ref class MyObject
{
public:
int x;
int y;
int rx;
int ry;
};
private: System::Void FormProperty_Load(System::Object^ sender, System::EventArgs^ e)
{
MyObject^ myObject=gcnew MyObject();
propertyGrid1->SelectedObject = myObject;
}

I had used public property to solve this problem. But... I meet another problem.
If SelectedObject is a nested object like basicobject, how to show the parameters of basiceffect in PropertyGrid?
public ref class BasicEffect
{
public:
BasicEffect(void)
{
}
virtual ~BasicEffect()
{
}
public:
[Browsable(true)]
property System::Boolean loop
{
bool get()
{
return _loop;
}
void set(System::Boolean value)
{
_loop=value;
}
}
private: System::Boolean _loop;
};
public ref class UIObject
{
public:
UIObject(void){_basiceffect=gcnew BasicEffect()};
virtual ~UIObject(void){};
public:
[Browsable(true)]
property int x
{
int get()
{
return _x;
}
void set(int value)
{
_x=value;
}
}
public:
[Browsable(true)]
property BasicEffect^ basiceffect2
{
BasicEffect^ get()
{
return _basiceffect2;
}
void set(BasicEffect^ value)
{
_basiceffect2=value;
}
}
private: int _x;
private: BasicEffect^ _basiceffect2;
};

first please download the PDFLibNet.dll from here: http://www.codeproject.com/KB/files/xpdf_csharp/PDFViewer.zip[^]
it's ok like this:
<br />
Assembly a = Assembly.LoadFile("PDFLibNet.dll");<br />
but exception like this:
byte[] b = File.ReadAllBytes("PDFLibNet.dll");<br />
Assembly a = Assembly.Load(b);<br />
throwing FileLoadException, telling me it could not verify the code or could not pass policy check. .net thinks that it is not a valid assembly.
I found a solution here: http://nonodes.spunow.co.uk/2009/04/assemblyload-c-cli-assembly-gives.html[^] telling me to build the C++ assembly with /clr:safe, but is there any other way out?

I want to modify the AutoScrollMinSize of Form1 by the code as below:
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e)
{
this->AutoScrollMinSize.Width=1000;
this->AutoScrollMinSize.Height=1000;
}
But it still not be active. Could somebody know how to modify the AutoScrollMinSize of Form1?
PS:already set Form1's AutoScroll as True.

a Size is a struct, hence a value type; you can't just modify part of it to modify the object. Assign a new Size with the width AND height you want.

Size is a struct, so when you directly modify its properties, you are actually modifying a copy of it. (Actually modifying two copies of it in your code, one for width and another for height ).
Use something like this:
this->AutoScrollMinSize = gcnew Size(1000,1000);

Could somebody know how to put any type controls on Toolstrip?
I want to put TrackBar and DomainUpDown controls to the Toolstrip.

System::IntPtr intPtr = pBitmap->GetHbitmap();

Assuming HBITMAP's type is defined somewhere (it is a HANDLE,
which is a void*)
HBITMAP hbitMap = intPtr.ToPointer();

FolderBrowserDialog FolderBrowserDialog1;
//FolderBrowserDialog1.RootFolder=System::Environment::SpecialFolder::Startup;

Something like,
FolderBrowserDialog folderBrowser;
folderBrowser.SelectedPath = Application::StartupPath;
Best wishes,

The application's current working directory can be obtained
with System::IO::Directory::GetCurrentDirectory().
The current working directory is not necessarily the same as
the startup path

My CLR project have many Split Containers, one Container has a customed user control.
I want to Render a cylinder with DirectX9 on the user control.
Could somebody tell how to get windows handle of user control or render with DirectX?

It depends on how your "customized user control" is implemented. However, it comes down to using the windows handle (HWND) and passing that to your DirectX device.
If you're using MFC, everything derives from CWnd. You'll want to use CWnd::m_hWnd.
If you're using Windows Forms with C++/CLI, everything will derive from Control, and you can use Control.Handle.
