Body
<p>I compiled the following code:</p> <pre><code>// Triangle.cpp // Our first OpenGL program that will just draw a triangle on the screen. #include <GLTools.h> // OpenGL toolkit #include <GLShaderManager.h> // Shader Manager Class #ifdef __APPLE__ #include <glut/glut.h> // OS X version of GLUT #else #define FREEGLUT_STATIC #include <GL/glut.h> // Windows FreeGlut equivalent #endif GLBatch triangleBatch; GLShaderManager shaderManager; /////////////////////////////////////////////////////////////////////////////// // Window has changed size, or has just been created. In either case, we need // to use the window dimensions to set the viewport and the projection matrix. void ChangeSize(int w, int h) { glViewport(0, 0, w, h); } /////////////////////////////////////////////////////////////////////////////// // This function does any needed initialization on the rendering context. // This is the first opportunity to do any OpenGL related tasks. void SetupRC() { // Blue background glClearColor(0.0f, 0.0f, 1.0f, 1.0f ); shaderManager.InitializeStockShaders(); // Load up a triangle GLfloat vVerts[] = { -0.5f, 0.0f, 0.0f, 0.5f, 0.0f, 0.0f, 0.0f, 0.5f, 0.0f }; triangleBatch.Begin(GL_TRIANGLES, 3); triangleBatch.CopyVertexData3f(vVerts); triangleBatch.End(); } /////////////////////////////////////////////////////////////////////////////// // Called to draw scene void RenderScene(void) { // Clear the window with current clearing color glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); GLfloat vRed[] = { 1.0f, 0.0f, 0.0f, 1.0f }; shaderManager.UseStockShader(GLT_SHADER_IDENTITY, vRed); triangleBatch.Draw(); // Perform the buffer swap to display back buffer glutSwapBuffers(); } /////////////////////////////////////////////////////////////////////////////// // Main entry point for GLUT based programs int main(int argc, char* argv[]) { gltSetWorkingDirectory(argv[0]); glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH | GLUT_STENCIL); glutInitWindowSize(800, 600); glutCreateWindow("Triangle"); glutReshapeFunc(ChangeSize); glutDisplayFunc(RenderScene); GLenum err = glewInit(); if (GLEW_OK != err) { fprintf(stderr, "GLEW Error: %s\n", glewGetErrorString(err)); return 1; } SetupRC(); glutMainLoop(); return 0; } </code></pre> <p>But when i try to execute it the program crash, then the debugger gives me the following error:</p> <pre><code>Excepción no controlada en 0x00000000 en Triangle.exe: 0xC0000005: Infracción de acceso al leer la ubicación 0x00000000. </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
