如何在C#中创建数学输入面板?
我试图将它放入一个dll并调用它但它立即关闭.
#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;
}
