Forms MS Access 2010表单框控件源IIF语句

当我试图将我的IIF语句放入我为计算表单上的分数而创建的框中时，我遇到了最大字符数问题。方框代码为：

=IIf([cbov1]="na" And [cbov2]="na" And [cbov3]="na" And [cbov4]="na" And [cbov5]="na" And [cboV6]="na" And [cboV7]="na" And [cboV8]="na" And [cboV9]="na" And [cboV10]="na" And [cboV11]="na" And [cboV12]="na" And [cboV13]="na" And [cboi1]="na" And [cboi2]="na" And [cboi3]="na" And [cboi4]="na" And [cbop1]="na" And [cbop2]="na" And [cbop3]="na" And [cbop4]="na" And [cbop5]="na" And [cbop6]="na" And [cbop7]="na" And [cbop8]="na" And [cbop9]="na" And [cbop10]="na" And [cbop11]="na" And [cbof1]="na" And [cbof2]="na" And [cbof3]="na" And [cbof4]="na" And [cbof5]="na" And [cbof6]="na" And [cbof7]="na" And [cbof8]="na" And [cbof9]="na" And [cbof10]="na" And [cbom1]="na" And [cbom2]="na" And [cbom3]="na" And [cbom4]="na" And [cbom5]="na" And [cbom7]="na" And [cbom8]="na" And [cbom9]="na" And [cbom10]="na" And [cbom6]="na",0,(IIf([cboV1]="yes",0,0)+IIf([cbov2]="yes",0,0)+IIf([cbov3]="yes",0,0)+IIf([cbov4]="yes",0,0)+IIf([cbov5]="yes",0,0)+IIf([cboV6]="yes",0,0)+ IIf([cboV7]="yes",0,0)+ IIf([cboV8]="yes",0,0)+ IIf([cboV9]="yes",0,0)+ IIf([cboV10]="yes",0,0)+ IIf([cboV11]="yes",0,0)+ IIf([cboV12]="yes",0,0)+ IIf([cboV13]="yes",0,0)+IIf([cboi1]="yes",5,0)+IIf([cboi2]="yes",3,0)+IIf([cboi3]="yes",3,0)+ IIf([cboi4]="yes",4,0)+IIf([cbop1]="yes",5,0)+IIf([cbop2]="yes",5,0)+IIf([cbop3]="yes",5,0)+IIf([cbop4]="yes",5,0)+ IIf([cbop5]="yes",5,0)+ IIf([cbop6]="yes",4,0)+ IIf([cbop7]="yes",4,0)+ IIf([cbop8]="yes",4,0)+ IIf([cbop9]="yes",4,0)+ IIf([cbop10]="yes",2,0)+IIf([cbop11]="yes",2,0)+IIf([cbof1]="yes",1,0)+IIf([cbof2]="yes",1,0)+IIf([cbof3]="yes",1,0)+IIf([cbof4]="yes",1,0)+ IIf([cbof5]="yes",1,0)+ IIf([cbof6]="yes",1,0)+ IIf([cbof10]="yes",0,0)+ IIf([cbof7]="yes",3,0)+ IIf([cbof8]="yes",3,0)+ IIf([cbof9]="yes",3,0)+IIf([cbom1]="yes",5,0)+IIf([cbom2]="yes",1,0)+IIf([cbom3]="yes",1,0)+IIf([cbom4]="yes",1,0)+IIf([cbom5]="yes",1,0)+IIf([cbom6]="yes",1,0) +IIf([cbom7]="yes",3,0) +IIf([cbom8]="yes",2,0) +IIf([cbom9]="yes",5,0) +IIf([cbom10]="yes",5,0))/(IIf([cboV1]="na",0,0)+IIf([cbov2]="na",0,0)+IIf([cbov3]="na",0,0)+IIf([cbov4]="na",0,0)+IIf([cbov5]="na",0,0)+IIf([cboV6]="na",0,0)+ IIf([cboV7]="na",0,0)+ IIf([cboV8]="na",0,0)+ IIf([cboV9]="na",0,0)+ IIf([cboV10]="na",0,0)+ IIf([cboV11]="na",0,0)+ IIf([cboV12]="na",0,0)+ IIf([cboV13]="na",0,0)+IIf([cboi1]="na",0,5)+IIf([cboi2]="na",0,3)+IIf([cboi3]="na",0,3)+ IIf([cboi4]="na",0,4)+IIf([cbop1]="na",0,5)+IIf([cbop2]="na",0,5)+IIf([cbop3]="na",0,5)+IIf([cbop4]="na",0,5)+ IIf([cbop5]="na",0,5)+ IIf([cbop6]="na",0,4)+ IIf([cbop7]="na",0,4)+ IIf([cbop8]="na",0,4)+ IIf([cbop9]="na",0,4)+ IIf([cbop10]="na",0,2)+ IIf([cbop11]="na",0,2)+IIf([cbof1]="na",0,1)+IIf([cbof2]="na",0,1)+IIf([cbof3]="na",0,1)+IIf([cbof4]="na",0,1)+ +IIf([cbof5]="na",0,1)+ +IIf([cbof6]="na",0,1)+ +IIf([cbof7]="na",0,3)+ +IIf([cbof8]="na",0,3)+ +IIf([cbof9]="na",0,3)+ +IIf([cbof10]="na",0,0)+IIf([cbom1]="na",0,5)+IIf([cbom2]="na",0,1)+IIf([cbom3]="na",0,1)+IIf([cbom4]="na",0,1)+IIf([cbom5]="na",0,1)+IIf([cbom6]="na",0,1) +IIf([cbom7]="na",0,3) +IIf([cbom8]="na",0,2) +IIf([cbom9]="na",0,5) +IIf([cbom10]="na",0,5)))*(IIf([cbov1]="no" Or [cbov2]="no" Or [cbov3]="no" Or [cbov4]="no" Or [cbov5]="no" Or [cboV6]="no" Or [cboV7]="no" Or [cboV8]="no" Or [cboV9]="no" Or [cboV10]="no" Or [cboV11]="no" Or [cboV12]="no" Or [cboV13]="no",0,1))

评分的目的是得分为“是”，得分为“否”，然后将NA从总分中删除。因此，如果一个人67分中有67分，他们会得到100分。如果所有问题的答案都是“是”或“否”，则最高分为100分。我需要计算所有部分，因为CBOV1-13规定，如果答案为“否”，则分数自动为0%

我不知道通过“属性”表在“控制源”框的“表达式生成器”中获得的最大字符的解决方法

任何关于这个问题的解决方法的帮助，或者如何使代码缩短并适合相同的最终结果，都将是一个巨大的帮助。

首先，我会尝试将我的字段设置为数字0,1,2，而不是na，是，否 然后你可以使用加法…IIF{cvb01+Cvb02+cvb03=0，0，…else

使用字符串 我可以想出两种方法。一种是在公式中使用串联 IIF[cvb01]&[cvb02]&[cvb03]=纳纳纳，0，…其他

我更倾向于编写一个函数来处理它

dim NAcount as integer
Dim YesCount as integer
Dim NoCount as integer

dim ctr as integer
dim StrAns as string

for ctr = 1 to 10
 StrAns = Fields ("cvb" & Ctr)

Select case StrAns
   Case "NA"
     NaCount = NACount + 1
     '...add values here

   Case "Yes"
     '...more values go here

   Case "No"
     '... more values
End Select

Next Ctr
...

你确定你的表设计已经规范化了吗？你能澄清这个问题吗？@Northcat当你说写函数时，我会在Access的查看代码部分这样做吗？我对VBA代码不太熟悉，所以当你有了…这应该是插入的东西吗？接下来是如果我在VBA代码中这样做，分数会显示在f上吗orm作为持续计算？
