Ошибка 438 в vba excel

First of all, you should know, that some of functions, used on the worksheet, have limitations. So my point is avoid of using them in VBA, if it is not necessary.
For example, function POWER() returns error on attempt to raise a zero to zero. An alternative is to use 0 ^ 0 combination, which is exactly doing the same, but looks more simply and operates without such error.
But also there is no embedded alternative in VBA to the FACT() function, so you can use it, or simply add your own function factor() — it’s uppon your choise.

If you just have started learning VBA, I would recomend you to use Option Explicit. It will help you to find out, which variables are not defined, and sometimes to avoid errors related to variable names missprint.

Here is your code, fixed and a little bit optimized:

Option Explicit' It is an option that turns on check for every used variable to be defined before execution. If this option is not defined, your code below will find undefined variables and define them when they are used. Good practice is to use this option, because it helps you, for example to prevent missprinting errors in variable names.

Sub Bezier()
    Dim C as Double , t As Double
    Dim k  As Long, n As Long, i As Long
    n = 3
    For i = 0 To 100
        t = i * 0.01
        Cells(i + 2, 6) = 0
        Cells(i + 2, 7) = 0
        For k = 0 To n
            C = (WorksheetFunction.Fact(n) / WorksheetFunction.Fact(k)) / WorksheetFunction.Fact(n - k)
            Cells(i + 2, 6) = Cells(i + 2, 6).Value + Cells(k + 2, 1).Value * C * (t ^ k) * ((1 - t) ^ (n - k))
            Cells(i + 2, 7) = Cells(i + 2, 7).Value + Cells(k + 2, 2).Value * C * (t ^ k) * ((1 - t) ^ (n - k))
        Next
    Next
End Sub

UPDATE
Here are some examples of factorial calculations.

    Public Function fnFact(number) ' a simple cycle example of Factorial function
    Dim tmp As Long ' new temporary variable to keep the "number" variable unchanged
    tmp = number
    fnFact = number
    While tmp > 1
        tmp = tmp - 1
        fnFact = fnFact * tmp
    Wend
End Function

Public Function fnFactR(number) ' a simple example of recursive function for Factorial calculation
    If number > 0 Then
        fnFactR = fnFactR(number - 1) * number ' function calls itself to continue calculations
    Else
        fnFactR = 1 ' function returns {1} when calculations are over
    End If
End Function

Sub Factor_test() 'RUN ME TO TEST ALL THE FACTORIAL FUNCTIONS
    Dim number As Long
    number = 170 ' change me to find Factorial for a different value
    MsgBox "Cycle Factorial:" & vbNewLine & number & "!= " & fnFact(number)
    MsgBox "WorksheetFunction Factorial:" & vbNewLine & number & "!= " & WorksheetFunction.Fact(number)
    MsgBox "Recursive Factorial:" & vbNewLine & number & "!= " & fnFactR(number)
End Sub

All those functions are available to calculate Factorial only for numbers before 170 inclusively, because of large result value.
So for my PC the limitation for WorksheetFunction.Fact() function is also 170.
Let me know, if your PC has different limitation for this function, — it’s quite interesting thing.

UPDATE2
It is recomended to use Long data type instead of Integer each type when integer (or whole number) variable is needed. Long is slightly faster, it has much wider limitations and costs no additional memory. Here are proof links:
1. MSDN:The Integer, Long, and Byte Data Types
2. ozgrid.com:Long Vs Integer
3. pcreview.co.uk:VBA code optimization — why using long instead of integer?
Thanks for @Ioannis and @chris neilsen for the information about Long data type and proof links!

Good luck in your further VBA actions!

Frequently encountering Run-time error ‘438′: Object doesn’t support this property or method whenever you try to start work in Excel?

What Are The Circumstances In Which Run-Time Error 438 In Excel Occurs?

There is not any specific reason for encountering this Excel runtime error 438: Object doesn’t support this property or method.

It is found that this Excel runtime error 438 occurs under several circumstances. So check this out:

• When anyone tries to make use of variables for workbooks and worksheet names.
• When executing a program within which form is already allotted to a variable. And that specific variable is now been used for accessing control over the form.
• This error also occurs when an installed AMD driver becomes out of date.
• The Macro you are using is maybe a wrong one or maybe it’s not working. Ultimately this will throw Excel runtime error 438.
• Runtime error 438 also encounters when you are trying to execute the designed macro of MS Excel previous version, into the latest MS Excel application.
• At the time of creating a custom toolbar in their Excel worksheet. User encounters a task failure error message i.e. “Object doesn’t support this property or method: Run-Time Error 438.
• In another instance in which this error occurs, the user tries to run the Microsoft VB for Excel macro. This macro tries to set the Excel worksheet properties but fails to complete this task which ultimately results in runtime error 438 in Excel.

How To Fix Runtime Error 438 In Excel?

Fix 1# MS Office Version Supporting Issue

Runtime error 438 in Excel also encounters while trying to work with the outdated macro function designed in older version MS Office application in some latest version of MS Office.

Even after trying all the above fixes if the Excel Object doesn’t support this property or method error won’t be resolved then let us inform by commenting in our comment section.

David Zemens got your answer.

Here’s how to avoid repeating it.

Looking at this line:

For Each item In Worksheets("Collector").SlicerCaches("Slicer_RptDate").SlicerItems

If we made every statement explicit, it would look like this:

For Each item In Worksheets.Item("Collector").SlicerCaches.Item("Slicer_RptDate").SlicerItems

In other words:

Worksheets.Item("Collector") _
          .SlicerCaches.Item("Slicer_RptDate") _
                       .SlicerItems

That’s a lot of member accesses for a single instruction.

By introducing intermediate variables…

Dim collectorSheet As Worksheet
Set collectorSheet = Worksheets("Collector")

Dim rptDateSlicerCache As SlicerCache
Set rptDateSlicerCache = collectorSheet.SlicerCaches("Slicer_RptDate") '*

For Each item In rptDateSlicerCache.SlicerItems
    '...
Next

…you could have noticed while typing the line marked with a '* comment, that IntelliSense doesn’t offer SlicerCaches as a member of collectorSheet.

Why? Because this:

Worksheets("Collector")

Returns an Object — and from that point on, you’re on your own: IntelliSense can’t help you with autocompletion, because members of an Object aren’t resolved until runtime.

By assigning that object to a Worksheet variable, you give yourself compile-time checking, and avoid that pesky runtime error 438.
