vb 引用部件 Public Declare Function vba引用另一个模块函数 同其他编程语言一样,VBA有可以创建类对象,VBA的类对象有自己的属性、方法、事件 公共变量和私有变量的区别 公共变量:可以跨模块调用,使用public关键词,在模块最上方声明 私有变量:只能在本模块类使用,使用private关键词定义,在模块最上方声明 函数、过程未...
在VBA中,`Declare`语句用于声明自定义函数或子程序。以下是`Declare`语句的语法: ```vba [Public|Private] Declare Function procedurename Lib "libname" aliasname [(arglist)] As returntype [Public|Private] Declare Sub procedurename Lib "libname" aliasname [(arglist)] ``` 其中,关键字部分包括: *...
这样可以在VBA代码中使用这个外部函数。 Private Declare Function的用法如下: Private Declare Function functionname Lib "libraryname" (parameters) As returntype 其中: - functionname是外部函数的名称。 - libraryname是包含外部函数的DLL文件的名称。 - parameters是外部函数接受的参数列表。 - returntype是外部函数...
