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;
};

But it still not be active. Could somebody know how to modify the AutoScrollMinSize of Form1?

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.

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

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

That is my partial source code:
public ref class PreviewView : public System::Windows::Forms::UserControl
{
LPDIRECT3DDEVICE9 d3ddev;
private: void initD3D(HWND hHandle)
{
d3d = Direct3DCreate9(D3D_SDK_VERSION); // create the Direct3D interface
ZeroMemory(pd3dpp, sizeof(*pd3dpp)); // clear out the struct for use
pd3dpp->Windowed = true; // program windowed, not fullscreen
pd3dpp->SwapEffect = D3DSWAPEFFECT_DISCARD; // discard old frames
pd3dpp->hDeviceWindow = hHandle; // set the window to be used by Direct3D
LPDIRECT3DDEVICE9 d3ddevTmp;
// create a device class using this information and information from the d3dpp stuct
d3d->CreateDevice(D3DADAPTER_DEFAULT,
D3DDEVTYPE_HAL,
hHandle,
D3DCREATE_SOFTWARE_VERTEXPROCESSING,
pd3dpp,
&d3ddevTmp);
d3ddev=d3ddevTmp;
}
When I create device, I must use another variable d3ddevTmp to return the D3DDevice and then set to d3ddev member variable. If I use d3ddev to create device, it will appear the error message as below:
Error 1 error C2664: 'IDirect3D9::CreateDevice' : cannot convert parameter 6 from 'cli::interior_ptr<Type>' to 'IDirect3DDevice9 **' d:\svn\......\PreviewView.h 121
Could somebody tell me how to solve this problem?

I have developed an application(managed + unmanaged) in VC++ using Visual Studio 2005. It can switch to either Console or to windows form depending upon the no of parameters passed to the application on command prompt console. Its basically a windows application but console has been implemented with the help of Attachconsole(), allocconsole() & freeconsole().
Now if i run a batch file, using command prompt console, all the output messages of the application can be seen on the console as shown below.
c:\test> testapp -f filename -l operationname -t otherparams
filename selected..
operation in progress..
operation completed successfully!!
But if i redirect the output of the console to a text file, i dont see any messages in the text file once the operation is complete.
for eg:
c:\test> testapp -f filename -l operationname -t otherparams >> logfile.txt
Clarifications i need are
1. am i missing something to log it in a text file?
2. Can output messages from the console be logged in such a fashion. if yes, how?
Thanks in advance for help/suggestions on the same.

This looks correct to me. What happens when you type a simple command (e.g. dir) instead of your application command line?
