当name在变量中时如何调用函数 [英] how to call a function when name is in a variable

问题描述

这里非常棘手。


我希望能够调用一个函数，但函数名在一个变量中。

代码是一个安全模块，查询存储

函数，表单，报告等名称以及某些组具有访问权限的表。表格，

报告等工作正常，因为我使用


DoCmd.OpenForm objectToRunName


但我该怎么办它当objectToRunName时有一个功能名称？


感谢您的帮助

Alan

really tricky one here.

I want to be able to call a function but the function name is in a variable.
The code is a security module that is querying a table that stores names of
functions, forms, reports etc and what access certain groups have. forms,
reports etc work fine as I use

DoCmd.OpenForm objectToRunName

but how do I do it when "objectToRunName" has a function name?

Thanks for any help

推荐答案

Alan，

你的意思是你的objectToRunName来自一个函数吗？

Dim strObject as string

strObject = YourFunction（ ）

DoCmd.OpenForm strObject

希望这会有所帮助

Alan,
Do you mean that your objectToRunName comes from a function?

Dim strObject as string
strObject=YourFunction()
DoCmd.OpenForm strObject

您好

我已经在vb6中完成了这项工作但忘记了如何。

但是我在access97帮助文件（有用的东西）中看到它说：


您可以使用Eval函数来计算结果的表达式

在文本字符串或数值中。

您可以构造一个字符串，然后将其传递给Eval函数，就像

字符串是实际表达式一样。 Eval函数计算

字符串表达式并返回其值。例如，Eval（1 + 1）

返回2.

如果传递给Eval函数一个包含名称的字符串

函数，Eval函数返回函数的返回值。

例如，Eval（" Chr

Hi
I have done this in vb6 but forgotten how.
However I see in the access97 help file (useful things) it says:

You can use the Eval function to evaluate an expression that results
in a text string or a numeric value.
You can construct a string and then pass it to the Eval function as if
the string were an actual expression. The Eval function evaluates the
string expression and returns its value. For example, Eval("1 + 1")
returns 2.
If you pass to the Eval function a string that contains the name of a
function, the Eval function returns the return value of the function.
For example, Eval("Chr
