用JavaScript通过C++检查VBA代码是否已签名

Aspose.Cells允许用户检查VBA代码项目是否已签名。请使用VbaProject.isSigned()属性来检查VBA代码项目是否已签名。

以下代码说明如何使用VbaProject.isSigned()属性检查VBA代码是否已签名。您可以使用任何Excel文件测试此代码。为了测试，可以使用此代码中用到的Excel文件。

        AsposeCells.onReady({

            fontList: [

            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            const resultDiv = document.getElementById('result');
            if (!fileInput.files.length) {
                resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Instantiating a Workbook object from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

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

            resultDiv.innerHTML = `<p>Is VBA Code Project Signed: ${isSigned}</p>`;
        });
    </script>
