很遗憾,我是一个语言模型AI,并不能直接在PowerPoint中获取文本框中所有的公式。但我可以告诉你一些思路:
你可以使用Microsoft Office Interop API,通过C++代码访问PowerPoint的COM组件,从而获取文本框中的内容。具体步骤如下:
1. 创建PowerPoint应用程序对象
```
_Application* pApp = NULL;
CoInitialize(NULL);
HRESULT hr = CoCreateInstance(CLSID_Application, NULL, CLSCTX_LOCAL_SERVER, IID__Application, (LPVOID*)&pApp);
if (FAILED(hr))
{
// 处理错误
return;
}
```
2. 打开PPT文件
```
_Document* pDoc = NULL;
hr = pApp->Presentations->Open(filePath, msoTrue, msoFalse, msoFalse);
if (FAILED(hr))
{
// 处理错误
return;
}
pDoc = pApp->ActivePresentation;
```
3. 遍历Slide中的Shapes,找到文本框
```
_Slide* pSlide = pDoc->Slides->Item(1);
for (int i = 1; i <= pSlide->Shapes->Count; i++)
{
Shape* pShape = pSlide->Shapes->Item(i);
if (pShape->HasTextFrame == msoTrue)
{
TextFrame* pTextFrame = pShape->TextFrame;
// TODO: 获取文本框中的内容
}
}
```
4. 在文本框中查找公式
公式是以“$”符号包含的文本,所以可以通过查找“$”符号来判断是否为公式。
```
if (pTextFrame->HasText == msoTrue)
{
TextRange* pTextRange = pTextFrame->TextRange;
BSTR bstrText = pTextRange->Text;
CString strText(bstrText);
SysFreeString(bstrText);
int pos = strText.Find(_T("$"));
while (pos >= 0)
{
// TODO: 判断是否为公式
pos = strText.Find(_T("$"), pos+1);
}
}
```
以上是大致思路,具体实现还需要根据你的具体需求进行调整和完善。同时,需要注意的是,使用COM组件需要了解一些基础知识,并且需要在编译时链接相应的库文件。
