试图建立在C＃中的数学输入面板 [英] Trying to create a Math Input Panel in C#

问题描述

如何创建在C＃中的数学输入面板？

How do I create a Math Input Panel in C#?

我试图把它变成一个DLL和调用它，但它只是关闭的时候了。

I have tried to put it into a dll and call it but it just closes right away.

#include <stdafx.h>
#include <atlbase.h>
#include "micaut.h"
#include "micaut_i.c"

extern "C" __declspec(dllexport) int run()
{
   CComPtr<IMathInputControl> g_spMIC; // Math Input Control
   HRESULT hr = CoInitialize(NULL);
   hr = g_spMIC.CoCreateInstance(CLSID_MathInputControl);
   hr = g_spMIC->EnableExtendedButtons(VARIANT_TRUE);
   hr = g_spMIC->Show();

   return hr;
}

我调用C＃DLL函数和面板弹出，但消失的时候了。有什么建议？

I call the dll function in C# and the panel pops up but disappears right away. Any suggestions?

推荐答案

在C＃项目中，添加对COM库的引用 micautLib 。然后你可以用下面的代码（在C＃）：

In your C# project, add a reference to the COM library micautLib. Then you can use the following code (in C#):

MathInputControl ctrl = new MathInputControlClass();
ctrl.EnableExtendedButtons(true);
ctrl.Show();

我不知道如果这正是你应该如何去做，但是这似乎。干净（完整的程序）工作。

I'm not sure if this is exactly how you're supposed to do it, but this seems to work cleanly (complete program).

using System;
using System.Windows.Forms;
using micautLib;

namespace MathInputPanel
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            MathInputControl ctrl = new MathInputControlClass();
            ctrl.EnableExtendedButtons(true);
            ctrl.Show();
            ctrl.Close += () => Application.ExitThread();
            Application.Run();
        }
    }
}
