QuestionCursor, converting code from vb.net to c++ Pin
Andreoli Carlo21-Apr-11 3:48
professionalAndreoli Carlo21-Apr-11 3:48 
hello i'm trying to convert this piece of code from vb

Private Structure IconInfo
       Public fIcon As Boolean
       Public xHotspot As Int32
       Public yHotspot As Int32
       Public hbmMask As IntPtr
       Public hbmColor As IntPtr
   End Structure

   <DllImport("user32.dll", EntryPoint:="CreateIconIndirect")> _
   Private Shared Function CreateIconIndirect(ByVal iconInfo As IntPtr) As IntPtr
   End Function

   <DllImport("user32.dll", CharSet:=CharSet.Auto)> _
   Public Shared Function DestroyIcon(ByVal handle As IntPtr) As Boolean
   End Function

   <DllImport("gdi32.dll")> _
   Public Shared Function DeleteObject(ByVal hObject As IntPtr) As Boolean
   End Function

   Public Function CreateCursor(ByVal bmp As Bitmap) As Cursor

       'Setup the Cursors IconInfo
       Dim tmp As New IconInfo
       tmp.xHotspot = _gHotSpotPt.X
       tmp.yHotspot = _gHotSpotPt.Y
       tmp.fIcon = False
       If _gBlackBitBack Then
           tmp.hbmMask = bmp.GetHbitmap(Color.FromArgb(0, 0, 0, 0))
           tmp.hbmColor = bmp.GetHbitmap(Color.FromArgb(0, 0, 0, 0))
       Else
           tmp.hbmMask = bmp.GetHbitmap()
           tmp.hbmColor = bmp.GetHbitmap()
       End If

       'Create the Pointer for the Cursor Icon
       Dim pnt As IntPtr = Marshal.AllocHGlobal(Marshal.SizeOf(tmp))
       Marshal.StructureToPtr(tmp, pnt, True)
       Dim curPtr As IntPtr = CreateIconIndirect(pnt)

       'Save the image of the cursor with the _gBlackBitBack effect
       'Not really needed for normal use.
       'I use it to create a screen shot with the gCursor included
       _gCursorImage = Icon.FromHandle(curPtr).ToBitmap

       'Clean Up
       DestroyIcon(pnt)
       DeleteObject(tmp.hbmMask)
       DeleteObject(tmp.hbmColor)

       Return New Cursor(curPtr)
   End Function

By now i traslate the all thing into:

public struct IconInfo
	{
		bool fIcon;
		int xHotspot;
		int yHotspot;
		System::IntPtr hbmMask;
		System::IntPtr hbmColor;
	};

	[System::Runtime::InteropServices::DllImport("user32.dll, EntryPoint:=CreateIconIndirect")]
	System::IntPtr CreateIconIndirect(System::IntPtr iconInfo);

	[System::Runtime::InteropServices::DllImport("user32.dll, CharSet:=CharSet.Auto")]
	bool  DestroyIcon(System::IntPtr handle);

	[System::Runtime::InteropServices::DllImport("gdi32.dll")]
	bool DeleteObject(System::IntPtr handl);

System::Windows::Forms::Cursor ^CreateCursor(Bitmap ^bmp, int xHotSpot, int yHotSpot)
			{
				
				// Setup the Cursors IconInfo
				IconInfo tmp;
				tmp.xHotspot = 3;
				tmp.yHotspot = 3;
				tmp.fIcon = false;
				bool _gBlackBitBack=false;
				if (_gBlackBitBack) {
					tmp.hbmMask = bmp->GetHbitmap(Color::FromArgb(0, 0, 0, 0));
					tmp.hbmColor = bmp->GetHbitmap(Color::FromArgb(0, 0, 0, 0));
				}
				else {
					tmp.hbmMask = bmp->GetHbitmap();
					tmp.hbmColor = bmp->GetHbitmap();
				}

				// Create the Pointer for the Cursor Icon
				IntPtr pnt= Marshal::AllocHGlobal(Marshal::SizeOf(tmp));
				Marshal::StructureToPtr(%tmp, pnt, true);
				
				IntPtr curPtr = CreateIconIndirect(pnt);

				// Clean Up
				DestroyIcon(pnt);
				DeleteObject(tmp.hbmMask);
				DeleteObject(tmp.hbmColor);

				
				return gcnew System::Windows::Forms::Cursor(curPtr);
			}

the problem is that i get the following error and i don't know how to get it solved:

error C2665: 'System::Runtime::InteropServices::Marshal::SizeOf' : none of the 2 overloads could convert all the argument types
1> c:\windows\microsoft.net\framework\v2.0.50727\mscorlib.dll: could be 'int System::Runtime::InteropServices::Marshal::SizeOf(System::Object ^)'
