vba基础知识汇总 1.工作簿事件写到THISWORKBOOK中,工作表事件写到sheet中,其他通用代码和函数子程序之类的写到模块中,窗体代码写到对应的窗体中,类相关的代码写到类模块中。2.If 句法,if 有两种写法,单行和块结构。 1、If 条件 Then 符合条件后的语句2、If ...
NewBook.SaveAs Filename:=fName Application.GetSaveAsFilename为调出标准的“另存为”对话框,获取用户文件名,但并不真正保存任何文件,然后使用代码保存文件。还有Application.GetOpenFileName可以调出标准的“打开”对话框。 5、关闭文件 关闭文件可以使用Workbooks集合或Workbook对象的 Close 方法。前者是关闭所有打开的工...
