判断文档是office打开 还是WPS打开

word和Excel文档的类型可以区分当前文档是用office打开还是wps打开，所以我们就获取文档类型，进行判断。wps打开的文档，它的文档类型是DOC、DOCX、XLS、XLSXoffice打开的文档，它的文档类型是Microsoft*****之类的

//strPath 文档路径//strExt 文档后缀BOOL OpenByWps(CString strPath, CString strExt){BOOL bWps = FALSE;//获取文件类型CString strVal(L"");SHFILEINFOA info;CStringA strA(strPath);LPCSTR ptr = strA;if (SHGetFileInfoA(ptr,FILE_ATTRIBUTE_NORMAL,&info,sizeof(info),SHGFI_TYPENAME | SHGFI_USEFILEATTRIBUTES)){strVal = info.szTypeName;if (strExt == L"doc" || strExt == L"docx"){if (strVal.Left(3) == L"DOC"){bWps = TRUE;}}else if (strExt == L"xls" || strExt == L"xlsx"){if (strVal.Left(3) == L"XLS"){bWps = TRUE;}}}return bWps;}
