使用这个例子可以添加自定义函数说明。
对于xp系统,Const Lib = """c:\windows\system32\user32.dll""",其他系统需要找到user32.dll的路径填入。输入代码保存后,需要重启excel改函数才能加入说明
代码原地址:http://www.j-walk.com/ss/excel/eee/eee009.txt
基本原理是利用了Excel4Macro来伪造一个自定义函数同名的dll,使用dll的说明在添加自定义函数的说明,而excel正常调用的函数为自定义函数,参数显示为dll。
其他添加自定义函数说明的方法为:http://hi.baidu.com/%B4%BA%B7%D6 ... a7b6ae6d811925.html |
