检查工作簿中的VBA项目是否用JavaScript通过C++签名

您可以通过**工具 > 数字签名…**菜单命令，使用Microsoft Excel来检查您的VBA项目是否已签名。同样，您也可以使用Aspose.Cells的Workbook.vbaProject属性以编程方式来检查。

用JavaScript检查工作簿中的VBA项目是否已签名

以下代码加载工作簿，并使用Workbook.vbaProject属性检测其VBA项目是否已签名。若已签名，返回true；否则返回false。

            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Accessing the VBA project and checking if it's signed
            const isSigned = workbook.vbaProject.isSigned;

            console.log("VBA Project is Signed: " + isSigned);
            document.getElementById('result').innerHTML = `<p>VBA Project is Signed: ${isSigned}</p>`;
        });
