Question

我在Excel文件中定义了一个宏，我希望使用Jacob 1.18 jar和dll从Java程序中调用它。

以下是我目前使用的代码段。

import java.io.File;

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;


public class TestJacob {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        File file = new File("C:\\TestJacob\\TestExcel_copy.xlsm");
        String macroName = "TestMacro";
        callExcelMacro(file, macroName);

    }

    private static void callExcelMacro(File file, String macroName) {
        ComThread.InitSTA(true);
        final ActiveXComponent excel = new ActiveXComponent("Excel.Application");
        try{
            excel.setProperty("EnableEvents", new Variant(false));

            Dispatch workbooks = excel.getProperty("Workbooks")
                    .toDispatch();

            Dispatch workBook = Dispatch.call(workbooks, "Open",
                    file.getAbsolutePath()).toDispatch();

            // Calls the macro
            Variant V1 = new Variant( file.getName() + macroName);
            Variant result = Dispatch.call(excel, "Run", V1);

            // Saves and closes
            Dispatch.call(workBook, "Save");

            com.jacob.com.Variant f = new com.jacob.com.Variant(true);
            Dispatch.call(workBook, "Close", f);

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            excel.invoke("Quit", new Variant[0]);
            ComThread.Release();
        }
    }
}

以下是我在调用宏时获得的异常。

com.jacob.com.ComFailException: Invoke of: Run
Source: Microsoft Excel
Description: Cannot run the macro 'TestExcel_copy.xlsmTestMacro'. The macro may not be available in this workbook or all macros may be disabled.

    at com.jacob.com.Dispatch.call(Dispatch.java:541)
    at TestJacob.callExcelMacro(TestJacob.java:38)
    at TestJacob.main(TestJacob.java:16)

我还通过以下步骤在Excel文件中启用了宏。

文件＆gt;选项
信任中心 - ＆gt;信任中心设置
宏设置
已启用＆＃34;启用所有宏＆＃34;和＆＃34;信任对VBA项目对象模型的访问
按＆＃34;确定＆＃34;

Answer 1

你需要将你的宏调用更改为

Variant result = Dispatch.call(excel, "Run", new Variant("\'"+file.getName()+"\'"+ macroName));

因为在Excel中，文件的名称在引号之间，所以如果没有“\”，它就找不到你的宏名称

Answer 2

调用宏时无需添加file.getname（）。只有macroname就足够了。

使用

Variant result = Dispatch.call(excel, "Run", new Variant(macroName));

Answer 3

确切地说：

Dispatch.call(excel, "Run", new Variant("\'"+file.getName()+"\'!" + macroName));

使用Jacob 1.18从Java调用宏
