[vtkusers] Creating a .dll with VTK.

[ferluduena]

Hi! I've been making some progress with VTK, and my idea is to build a .dll
in Visual studio, where I use VTK, and then, use it on a C# application.

I have my VTK project, which i made using CMake, which is a console
application, and looks like this:

//---------------------------------------------------------------------------//
#include <vtkVersion.h>
#include <vtkSmartPointer.h>
#include <vtkPolyData.h>
#include <vtkXMLPolyDataWriter.h>
#include <vtkContourFilter.h>
#include <vtkGaussianSplatter.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkJPEGReader.h>
#include <vtkImageData.h>
#include <vtkImageViewer2.h>
#include <vtkOrientationMarkerWidget.h>
#include <vtkAxesActor.h>
#include <vtkSurfaceReconstructionFilter.h>
#include <vtkReverseSense.h>

void recon(int x, int y, int z);
void recondemo(void);

int main(int argc, char *argv[])
{
	int key = 0;
	cout << "Ingresar 1 Para reconstruir imagenes a partir de archivos, o 0
para demo" << endl;
	cin >> key;
	if (key == 1)
	{
		int x, y, z;
		x = y = z = 0;
		recon(x, y, z);
	}
	else
	{
		recondemo();
	}
	  return EXIT_SUCCESS;

}

void recon(int x=0, int y=0, int z=0){}

void recondemo(void){}

//----------------------------------------------------------------------------//

So what i tried to do is going to the project's configuration in VS and
change Type of configuration from .exe to .dll. 

after compiling i tried calling the .dll from a C# application, but when i
run it i get an error saying the format is incorrect.

This is how i call the function in c#:


//------------------------------------------------------------------------------------//
class PlatformInvokeTest
{
    [DllImport("EmbedPointsIntoVolume.dll")]
    public static extern int recodemo();
    [DllImport("EmbedPointsIntoVolume.dll")]
    internal static extern int _flushall();
//------------------------------------------------------------------------------------//
}

So, i'm pretty sure this can be done... but can someone give me an idea on
how? I've read about different ways of calling a .dll ... but i'm pretty
sure i'm not building the .dll right, to begin with.

Hope someone can help me!

Thanks in advance!
