modifying C# file through another script ? unity code example

Example 1: accessing form controls from another class c#

public partial class Form1 : Form
{
//https://stackoverflow.com/questions/12983427/accessing-forms-controls-from-another-class
    // Static form. Null if no form created yet.
    private static Form1 form = null;

    private delegate void EnableDelegate(bool enable);

    public Form1()
    {
        InitializeComponent();
        form = this;
    }

    // Static method, call the non-static version if the form exist.
    public static void EnableStaticTextBox(bool enable)
    {
        if (form != null)
            form.EnableTextBox(enable);
    }

    private void EnableTextBox(bool enable)
    {
        // If this returns true, it means it was called from an external thread.
        if (InvokeRequired)
        {
            // Create a delegate of this method and let the form run it.
            this.Invoke(new EnableDelegate(EnableTextBox), new object[] { enable });
            return; // Important
        }

        // Set textBox
        textBox1.Enabled = enable;
    }
}

Example 2: how read a shader from another file c++

#include "GLShader.hpp"

#include <string>
#include <iostream>
#include <fstream>
#include <vector>
#include <algorithm>


std::string readFile(const char *filePath) {
    std::string content;
    std::ifstream fileStream(filePath, std::ios::in);

    if(!fileStream.is_open()) {
        std::cerr << "Could not read file " << filePath << ". File does not exist." << std::endl;
        return "";
    }

    std::string line = "";
    while(!fileStream.eof()) {
        std::getline(fileStream, line);
        content.append(line + "\n");
    }

    fileStream.close();
    return content;
}


GLuint LoadShader(const char *vertex_path, const char *fragment_path) {
    GLuint vertShader = glCreateShader(GL_VERTEX_SHADER);
    GLuint fragShader = glCreateShader(GL_FRAGMENT_SHADER);

    // Read shaders

    std::string vertShaderStr = readFile(vertex_path);
    std::string fragShaderStr = readFile(fragment_path);
    const char *vertShaderSrc = vertShaderStr.c_str();
    const char *fragShaderSrc = fragShaderStr.c_str();

    GLint result = GL_FALSE;
    int logLength;

    // Compile vertex shader

    std::cout << "Compiling vertex shader." << std::endl;
    glShaderSource(vertShader, 1, &vertShaderSrc, NULL);
    glCompileShader(vertShader);

    // Check vertex shader

    glGetShaderiv(vertShader, GL_COMPILE_STATUS, &result);
    glGetShaderiv(vertShader, GL_INFO_LOG_LENGTH, &logLength);
    std::vector vertShaderError((logLength > 1) ? logLength : 1);
    glGetShaderInfoLog(vertShader, logLength, NULL, &vertShaderError[0]);
    std::cout << &vertShaderError[0] << std::endl;

    // Compile fragment shader

    std::cout << "Compiling fragment shader." << std::endl;
    glShaderSource(fragShader, 1, &fragShaderSrc, NULL);
    glCompileShader(fragShader);

    // Check fragment shader

    glGetShaderiv(fragShader, GL_COMPILE_STATUS, &result);
    glGetShaderiv(fragShader, GL_INFO_LOG_LENGTH, &logLength);
    std::vector fragShaderError((logLength > 1) ? logLength : 1);
    glGetShaderInfoLog(fragShader, logLength, NULL, &fragShaderError[0]);
    std::cout << &fragShaderError[0] << std::endl;

    std::cout << "Linking program" << std::endl;
    GLuint program = glCreateProgram();
    glAttachShader(program, vertShader);
    glAttachShader(program, fragShader);
    glLinkProgram(program);

    glGetProgramiv(program, GL_LINK_STATUS, &result);
    glGetProgramiv(program, GL_INFO_LOG_LENGTH, &logLength);
    std::vector<char> programError( (logLength > 1) ? logLength : 1 );
    glGetProgramInfoLog(program, logLength, NULL, &programError[0]);
    std::cout << &programError[0] << std::endl;

    glDeleteShader(vertShader);
    glDeleteShader(fragShader);

    return program;
}
