编辑:新文件。我在访问 Form1 类中的公共函数时遇到问题。当我尝试使用它时找不到标识符。表格1:
#pragma once
#include "OpenGL.h"
#include "serialcom.h"
#include "calculations.h"
namespace GUI_1 {
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Drawing;
using namespace OpenGLForm;
/// <summary>
/// Summary for Form1
/// </summary>
public ref class Form1 : public System::Windows::Forms::Form
{
public:
Form1(void)
{
InitializeComponent();
OpenGL = gcnew COpenGL(this->panel4, this->label16, 785, 530);
}
void changelabel2(float num)
{
label2 -> Text = " " + num;
}
protected: ...
OpenGL.h:
#include "stdafx.h"
#ifndef opengl
#define opengl
#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glu32.lib")
#include <windows.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>
#include <math.h>
// Declare globals
...
using namespace System::Windows::Forms;
namespace OpenGLForm
{
public ref class COpenGL: public System::Windows::Forms::NativeWindow
{
public:
COpenGL(System::Windows::Forms::Panel ^ parentForm, System::Windows::Forms::Label ^ lbl, GLsizei iWidth, GLsizei iHeight)
{
CreateParams^ cp = gcnew CreateParams;
c_p_v v1, v2;
changelabel2(189);
...
所以这不起作用(上面,在“changelabel2”中)。也许是因为我没有使用类名?
这是我的主要内容:
#include "stdafx.h"
#include <string.h>
#include <iostream>
#include <stdio.h>
#include < vcclr.h >
#include < stdio.h >
#include < stdlib.h >
#include < vcclr.h >
#include "Form1.h"
#include "calculations.h"
#include "serialcom.h"
using namespace GUI_1;
[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Form1^ form = gcnew Form1();
Application::Run(form);
return 0;
}
调用 form.changelabel2 也不起作用。
