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);

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

FolderBrowserDialog FolderBrowserDialog1;

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.

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?

You have to "pin" d3ddev which is currently controlled by the GC. That is, assign it to a pin_ptr<D3DDevice>.

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?
