powerpoint 通过C++插入公式

可以使用Microsoft Office Equation Editor COM接口来通过C++插入PowerPoint公式。以下是示例代码：

#include <windows.h>
#include <ole2.h>
#include <oaidl.h>
#include <office10/msword.h>
#include <office10/msppt.h>
#include <office10/vbe6ext.h>
#include <office10/office.h>
#include <vcclr.h>

using namespace System;
using namespace System::Runtime::InteropServices;
using namespace Microsoft::Office::Core;
using namespace Microsoft::Office::Interop::PowerPoint;

int main(array<System::String ^> ^args)
{
    // 初始化COM
    CoInitialize(NULL);
    
    // 创建PowerPoint应用程序对象
    PowerPoint::Application^ pptApp = gcnew PowerPoint::Application();
    
    // 创建新演示文稿
    Presentation^ pptPresentation = pptApp->Presentations->Add(MsoTriState::msoTrue);
    
    // 在第一张幻灯片上插入公式
    Slide^ slide = pptPresentation->Slides->Item(1);
    Shape^ equationShape = slide->Shapes->AddOLEObject(100.0f, 100.0f, 200.0f, 100.0f, "Equation.3");
    equationShape->OLEFormat->Object->Editable = true;
    equationShape->OLEFormat->Object->Formula = "x = {-b ± √(b^2 - 4ac)}/2a";
    equationShape->OLEFormat->Object->Editable = false;
    
    // 保存演示文稿并退出PowerPoint应用程序
    pptPresentation->SaveAs("test.pptx", PowerPoint::PpSaveAsFileType::ppSaveAsOpenXMLPresentation);
    pptApp->Quit();
    
    // 释放COM对象
    Marshal::ReleaseComObject(slide);
    Marshal::ReleaseComObject(pptPresentation);
    Marshal::ReleaseComObject(pptApp);
    
    // 反初始化COM
    CoUninitialize();
    
    return 0;
}

此代码使用Microsoft Office Equation Editor插入一个公式，并将演示文稿保存为PPTX文件。在运行此代码之前，请确保已将Microsoft Office Equation Editor安装在计算机上。
