    Eu sempre trabalhei com projetos CLR, sendo assim quando precisava instanciar um objeto de uma classe de um projeto em outro projeto, bastava adicionar a referencia do projeto e colocar o using namespace. Agora estou fazendo projetos WIN32, mas não estou conseguindo mais fazer isso. Para conseguir fazer a mesma coisa, tive que além de colocar a reference e o namespace, tive que adicionar o .h da classe no additional include directories e tive que adicionar o .cpp da classe no projeto, esse método é o correto? Fazendo isso acabo passando dependência de um projeto, coisa que eu gostaria de evitar.

    é uma função que através dos valores RGB do pixel classifica o pixel em ciano, rosa, verde ou preto utilizando uma rede neural MLP

    Está função trabalha em cima de vários frames(Bitmaps) de um vídeo, porém o programa trava quando chega na linha de comando: "classificacao = ClassificarMLP(ptr[pix + 2], ptr[pix + 1], ptr[pix]);" e recebo está mensagem: AccessViolationException was unhandled Tentativa de leitura ou gravação em memória protegida. Normalmente, isso é uma indicação de que outra memória está danificada. Segue o código-fonte: void Orientacao(Bitmap imagem, ArrayList objetos, int qt_objetos, double raio) { int i,j; int classificacao; double raio_temp1,raio_temp2; Posicao ponto = new Posicao(); Bitmap image = (Bitmap)imagem.Clone(); BitmapData data = image.LockBits(new Rectangle(0, 0, image.Width, image.Height), ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb); unsafe { byte* ptr = (byte*)(data.Scan0); Int32 pix; for (i = 0; i < qt_objetos; i++) { if (((Objeto)objetos[i]).rotulo == 0) { for (j = 0; j < 90; j++) { raio_temp2 = j * 4 * 0.01745; raio_temp1 = Math.Cos(raio_temp2); raio_temp2 = Math.Sin(raio_temp2); if ((((Objeto)objetos[i]).ponto.x + (int)(raio * raio_temp1)) < data.Height && (((Objeto)objetos[i]).ponto.x + (int)(raio * raio_temp1)) > 0 && 3 * (((Objeto)objetos[i]).ponto.y + (int)(raio * raio_temp2)) < data.Width && 3 * (((Objeto)objetos[i]).ponto.y + (int)(raio * raio_temp2)) > 0) { pix = ((((Objeto)objetos[i]).ponto.x + (int)(raio * raio_temp1)) * data.Stride + 3 * (((Objeto)objetos[i]).ponto.y + (int)(raio * raio_temp2))); classificacao = ClassificarMLP(ptr[pix + 2], ptr[pix + 1], ptr[pix]); if (classificacao > -1) //ciano, rosa ou ver { j += 3; raio_temp2 = j * 4 * 0.01745; raio_temp1 = Math.Cos(raio_temp2); raio_temp2 = Math.Sin(raio_temp2); pix = ((((Objeto)objetos[i]).ponto.x + (int)(raio * raio_temp1)) * data.Stride + 3 * (((Objeto)objetos[i]).ponto.y + (int)(raio * raio_temp2))); classificacao = ClassificarMLP(ptr[pix + 2], ptr[pix + 1], ptr[pix]); ponto.x = ((Objeto)objetos[i]).ponto.x + (int)(raio * raio_temp1); ponto.y = ((Objeto)objetos[i]).ponto.y + (int)(raio * raio_temp2); if (classificacao > -1) { ponto = CentroideNovo(ponto, image, 1); j += 20; switch (classificacao) { case 0: //((Objeto)objetos[i]).ponto.ang = ((Objeto)objetos[i]).ponto.Angulo(ponto); //ciano break; case 1: ((Objeto)objetos[i]).ponto.ang = ((Objeto)objetos[i]).ponto.Angulo(ponto);//ImagemProcessada->Picture->Bitmap->Canvas->Brush->Color=(TColor)16744703; //rosa break; case 2: //((Objeto)objetos[i]).ponto.ang = ((Objeto)objetos[i]).ponto.Angulo(ponto); //verde break; } } } } else { j++; } } } } } image.UnlockBits(data); }

    consegui resolver o problema era : Onde tinha : private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { //if (video == nullptr) SAASCapturaNS::SAASCaptura^ video = (gcnew SAASCapturaNS::SAASCaptura()); button2->Enabled = true; button1->Enabled = false; Era pra ser : private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { //if (video == nullptr) video = (gcnew SAASCapturaNS::SAASCaptura()); button2->Enabled = true; button1->Enabled = false;

    Estou tentando fazer um programa que exibe em um picturebox os frames capturados por uma webcam, essa biblioteca SAASCapturaNS é que tem as funções de captura, mas o problema do programa está no uso da System::Windows::Forms::Timer, porque já consigo capturar uma única imagem, mas quando tento capturar uma sequencia usando o timer não dá certo.
