In a Class Module there is:
Private Enum colType
ID = "A"
SSN = "B"
lName = "H"
fName = "G"
End Enum
as a private member. Whenever the class initializes I get the Compile Error: Type Mismatch message. If I declare colType as Private Enum coltype As String. That gets highlighted red as an error and I get the message:
Compile Error: Expected end of statement
Is specifying the values of enumerated elements Unallowed in Excel VBA?
As written in the comments, this is not possible. There is possible workaround though that I used in the past. Have:
Private Enum colType
ID = 1
SSN = 2
lName = 3
fName = 4
End Enum
And then create a separate String property of function such as:
Public Property Get colType_String(colType) as String
Dim v as Variant
v= Array("A","B", ...)
colType_String = vba.cstr(v(colType))
End Property
This is not the most universal solution, but it is easy to implement and it does the job... If you have this in the class module already you can even use property on private colType variable and there is no need to have colType input into the property.
v(colType) exactly do?I quite like ex-man's solution in certain circumstances, for which reason I've upvoted it. The solution more often posited goes along the following lines:
Enum myEnum
myName1 = 1
myName2 = 2
myName3 = 3
End Enum
Function getEnumName(eValue As myEnum)
Select Case eValue
Case 1
getEnumName = "myName1"
Case 2
getEnumName = "myName2"
Case 3
getEnumName = "myName3"
End Select
End Function
Debug.Print getEnumName(2) prints "myName2"
I have been searching for a very long time for the answer to this question. I do not want to have to relist the contents of an Enum in either a Case statement or an array. I couldn't find the answer, but I have managed to do after finding the code somewhere to change Module content. An alteration of that has produced the following working code, to be placed in Module1:
Option Explicit
Enum MensNames
Fred
Trev = 5
Steve
Bill = 27
Colin
Andy
End Enum
Sub EnumStringTest()
MsgBox EnumString(Steve) & " = " & Steve
End Sub
Function EnumString(EnumElement As MensNames) As String
Dim iLineNo As Integer
Dim iElementNo As Integer
iElementNo = 0
EnumString = vbNullString
With ThisWorkbook.VBProject.VBComponents("Module1").CodeModule
' Find the Enum Start
For iLineNo = 1 To .CountOfLines
If InStr(.Lines(iLineNo, 1), "Enum MensNames") > 0 Then
Exit For
End If
Next iLineNo
' Find the required Element
iLineNo = iLineNo + 1
Do While InStr(.Lines(iLineNo, 1), "End Enum") = 0 And .Lines(iLineNo, 1) <> ""
If InStr(2, .Lines(iLineNo, 1), "=") > 0 Then
iElementNo = CLng(Mid(.Lines(iLineNo, 1), InStr(2, .Lines(iLineNo, 1), "=") + 1))
End If
If iElementNo = EnumElement Then
EnumString = Left(Trim(.Lines(iLineNo, 1)), IIf(InStr(1, Trim(.Lines(iLineNo, 1)), " ") = 0, 1000, InStr(1, Trim(.Lines(iLineNo, 1)), " ") - 1))
Exit Do
End If
iElementNo = iElementNo + 1
iLineNo = iLineNo + 1
Loop
End With
End Function
To improve the solution of Rich Harding, I use the enum to improve on readability and make it less prone to mistakes:
Enum myEnum
myName
someOtherName
lastName
End Enum
Function getEnumName(eValue As myEnum) As String
Select Case eValue
Case myName: getEnumName = "myName"
Case someOtherName: getEnumName = "someOtherName"
Case lastName: getEnumName = "lastName"
End Select
End Function
The long integers in the Enum could be Base-10 encodings. The ToAlpha function below converts the number to Base-26, represented with uppercase alphabet characters. To get the number, call the ToLong function with a string.
This would work up to 6 characters (anything above 2,147,483,647 overflows the Enum value).
Private Enum colType
ID = 0 'A
SSN = 1 'B
lName = 7 'H
fName = 6 'G
WORD = 414859
FXSHRXX = 2147483647 'Maximum long
End Enum
Sub test()
Debug.Print "ID: " & ToAlpha(colType.ID)
Debug.Print "SSN: " & ToAlpha(colType.SSN)
Debug.Print "lName: " & ToAlpha(colType.lName)
Debug.Print "fName: " & ToAlpha(colType.fName)
Debug.Print "WORD: " & ToAlpha(colType.WORD)
Debug.Print "FXHRXX: " & ToAlpha(colType.FXSHRXX)
End Sub
Function ToAlpha(ByVal n)
If n < 0 Or Int(n) <> n Then Exit Function 'whole numbers only
Do While n > 25
ToAlpha = Chr(n Mod 26 + 65) & ToAlpha
n = n \ 26 - 1 'base 26
Loop
ToAlpha = Chr(n + 65) & ToAlpha
End Function
Function ToLong(ByVal s)
s = UCase(s)
Dim iC
For i = 1 To Len(s)
iC = Asc(Mid(s, i, 1))
If iC < 65 Or iC > 90 Then 'A-Z only
ToLong = -1
Exit Function
End If
ToLong = ToLong * 26 + (iC - 64) 'base 26
Next
ToLong = ToLong - 1
End Function
ToLong(ByVal enumAlpha As String) As Long) and variables, and maybe edit to include the print output to make it clear that ToAlpha(WORD) actually prints "WORD".My solution of this looks like this:
Private Enum ColType
ID = 1
SSN = 2
lName = 3
fName = 4
End Enum
Private Function GetEnumName(ByVal value As ColType)
GetEnumName = Choose(value, _
"A", _
"B", _
"H", _
"G" _
)
End Function
Using Choose looks more tidy.
Sample usage: ... = GetEnumName(ColType.ID)
I hope this help

Instead of Enum, define a Type(struct)
Public Type colType
ID As String
SSN As String
lName As String
fName As String
End Type
And then create a object of type colType and set desired values to it.
Public myColType As colType
myColType.ID = "A"
myColType.SSN = "B"
myColType.lname = "H"
myColType.fName = "G"
