I am working on vba macros. I was trying to use a dictionary. But it is giving error 457 with debugger pointing to toprow.Add ActiveCell.value, val. Can anyone please tell the issue? I even used Cstr(activecell.value), Cstr(val) as mentioned in one of the answer on similar issue.
Dim toprow As New Dictionary, Dictkey As Variant
Dim val As String
Range("A1").Activate
i = 0
Do Until i = ColLen
val = Chr(65 + i)
toprow.Add ActiveCell.value, val
i = i + 1

Adding keys with dictionaries is only possible when a key does not already exist. Accidentally you could entered the key before, or you are watching the key with the debug watcher, creating the key instanteneously. (= If you watch a certain key in a dictionary it gets created if it doesn’t already exist).
You have to
- make sure you are not watching the key with the debugger
- create unique entries by testing on
d.Exists(keyname)and then use thed.Add keyname, valuemethod - alternatively you can default to overwrite existing keys by using
d.Item(keyname) = value

You can also add some very basic error handling, if all you wish to do is skip over the record throwing this error. I simply inserted the below line immediately above the one which was generating this error for me, and now it happily moves along, ignoring duplicate keys which used to throw this error.

I was getting the same error message: «Error This key is already associated with an element of this collection». In my case, the problem was that I had this:
'assign values to properties
Property Let EmployeeName(Valor As String)
m_employeename = Valor
End Property
Property Let EmployeeID(Valor As String)
m_employeename = Valor
End Property
I was supposed to have this:
'assign values to properties
Property Let EmployeeName(Valor As String)
m_employeename = Valor
End Property
Property Let EmployeeID(Valor As String)
m_employeeid = Valor
End Property
Maybe you just have to double check your «Property Let» code to see if you are using appropriate names for those variables that are private in your class.

#5 14.03.2015 14:31:20 ALFA, но ошибка по прежнему повторяется..[/QUOTE]Basic предполагает, что на метке line2 начинается обработчик ошибки. Он должен завершаться оператором Resume или выходом из процедуры. Если в обработчике ошибок возникает ошибка, она уже не обрабатывается *) и происходит останов. Это и происходит у Вас при следующем повторяющемся элементе, т.к. Basic не встретил оператор Resume и считает, что работает обработчик ошибок. Простейший обработчик ошибок должен выглядеть так:
*) Для обработки ошибок в обработчике ошибок можно использовать оператор On Error GoTo -1 |

#6 18.03.2015 14:48:29 Doober, Ваш вариант успешно подошел, работает, Спасибо!
не подходит, так как если ключ уже существует в коллекции мне необходимо было перейти в определенный участок кода, видимо я привел не совсем подходящий пример( Необходимо было в случае ошибки перейти не к следующему элементу а именно перепрыгнуть на line2: Всем спасибо за предложенные варианты решения! |

You test if r.Offset(,5) already exists but not if r.Offset(,6) exists before you try and add it (so you could simply test if it exists first). If it does exist, what do you want to do though? Just not add it and carry on with the rest of the code, or something else?

Thank you for the reply. Would you please explain more, I think I got lost.

This line:
If Not dic.exists(r.Offset(, 5).Value) Then
checks if the value contained in r.Offset(,5) already exists in the dictionary’s Keys. If it doesn’t already exist, then this line adds it to the Keys:
dic.Add r.Offset(, 5).Value, Nothing
That will work fine and you won’t get an error as you never try and add a value into the dictionary that already exists.
However, immediately following the line above, you try and add another value to the dictionary with:
dic.Add r.Offset(, 6).Value, Nothing
But you don’t first check that this value doesn’t already exist in the Dictionary — you get the error because it is already in the Dictionary (ie the value has been added in previously).
If you did check for r.Offset(,6).Value’s existence first, you could skip trying to add an already-existing value. This would mean, however, that your two arrays (m_price and m_serial) would be ‘out of step’. Because I don’t know exactly why you are doing this, I am not sure if this is important to you.

Thank you very much for your help.It is now working after eliminating that line.
Thanks again.
