Calling A Custom Function Within VBA
Sep 9, 2009
I have created a custom Function in excel. I would like to create a custom button so I can run this funtion with a Click of a button unstead of typing it in or clicking on the insert function button. I am not sure if this is possible to have VB call a custom function. Below is my VB for the Custom Function. I basically want the custom button to open the formula in excel.
Public Function CreateFlexstring(Company As String, Cost_Center As String, _
Division As String, Geography As String)
CreateFlexstring = Company & "-" & Cost_Center & "-" & Division & "-" & Geography
End Function

I can create events in my custom classes. When do I even want to raise an event like this instead of calling the corresponding Sub?
I imagine that I can create an event called OnColorChange or I can create a sub called OnColorChange.
Why would I want to create an event?

I have a function
VB:
Function f1(Matrix As Range)
'Does something and returns f1 = a double
End Function
And a second function which defines and constructs a matrix of doubles to use as an argument in f1 to return a double:
VB:
Function f2(dD As Double)
Dim MatrixRed() As Double
Redim MatrixRed(1 To dD, 1 To 10)
For i = 1 To dD
For j = 1 To 10
MatrixRed(i, j) = i * j
Next
Next
f2 = f1(MatrixRed)
End Function
I get an output error (#VALUE). I think it has something to do with MatrixRed not being a range anymore?

I guess I just don't understand the basics of calling a function. I have the following function in a standard module:
Function CleanUp(ws As Worksheets)
ws. Range("A2:P100").ClearContents
End Function
I have this code in a worksheet module:
Sub Trying_to_call_a_function()
CleanUp (ThisWorkbook.Worksheets("Month End"))
End Sub
But when I run the routine that calls the "CleanUp" function, I get the message: "Object doesn't support this property or method." I have tried changing the Function to this: CleanUp (ws as Worksheet) [instead of (ws as WorksheetS)]. Yet, this does not change anything.

I need to extract the filename “My Excel File” from Worksheets(“Sheet1”).Range(“A1”), whose value = C:Documents and Settingsuser1DesktopMy Excel File
I found on Chip Pearson’s site a Function TrimToChar which, using SearchFromRight and a TrimChar of “” will trim OFF the filename “My Excel File”, leaving the Path.
But, I think I could use his function to tell me the number of characters in the Path and then use that to extract the remaining characters from the total character length (Mid Function)
Problem is, I don’t have a clue how to call a Function in VBA to work on Worksheets(“Sheet1”).Range(“A1”). How do you set the InputText , TrimChar, & SearchFromRight?????
(eventually, this will be in a loop, where I extract the filename from a Dynamic Named Range (list) in Column A)

I have an add-in that has one function in it. We plan on adding more, but not until we figure out what's happening. The one function is a Select- Case statement...send the function an alpha code and it returns a numeric account number based on the alpha. About 20 "cases" in total. The add-in loads fine and the function works fine from a spreadsheet cell. However, we're getting differing results when we try to access the function from VBA code. I've been able to duplicate this several times on three different computers on our network.
The VBA code will work fine, several times and then on the 4th or 5th attempt it will cause Excel to crash ==> "Microsoft Office Excel has encountered a problem and needs to close. We are sorry for the inconvenience." If I " recover" the crashed file, comment out the line to call the function, run the program again it works. Then I can un-comment the line, re-run the program and it works fine again for 4 or 5 more attempts. I've tried running the Repair tool already. I've also copied the code out of the spreadsheet and started a new file. The same errors occur...works 4 or 5 times and then crashes the program. The add-in and the spreadsheet exists on networked drives.

I have a User Defined Function (for finding the next minimum value in a range) that is not working for nonconcurrent ranges when called from within a worksheet. It returns #VALUE!
This works: =nextmin(A11:A17)
This does not work: =nextmin(D13,E13,F13,F16)
However calling the function from within vba works:

how to properly write this kind of commands!
v_1 = Sheets("WB_Input").Cells(i, 2) 'It's gonna be a numeric value like 10
v_2 = "E"
v_3 = Sheets("WB_Input").Cells(i, j) 'It's gonna be a numeric value like 12
Sheets("WB_Output").Cells(i, j) = "=CONCATENATE(" & v_1 & "," & v_2 & "," & v_3 & ")"
Thing is once I look at the WB_Output Sheet what I see is an error and the cell shows this: =Concatenate(10,E,12)
So logically the problem is that I need to make it show up as =Concatenate("10","E","12")
Btw, I can't just put v_1 & v_2 & v_3, cause Excel understands "E" as exponential!

the macro works fine until it executes the paste values. At that point, the macro jumps to the "CountThem" function which is located in another workbook. The data that I am copy/pasting is in no way connected to any cells that are using that function. Although, other values in the workbook are passed down from data that uses that function.
I am still in the dark ages using Excel 2000.
This is the code for my macro.
Code:
Sub Current_to_Raw()
'
' Current_to_Raw Macro
' Macro recorded 2/12/2014 by
'
'
Range("N14").Select
[code]....

Imagine i have 2 columns: Open and Close, both of these got numbers like
1 ---- 2
3 ---- 1
4 ---- 10
and so on. I had to make a function which checks if some number is in between any of those Open and Close numbers and count how many, for example: im searching for number 1.3, so according to previously drawn table i would get answer of 2, because 2 is in between 1----2 and 3-----1, i achieved this by a simple function:
=IF(OR(AND(Bendras!$J$1>=Table1[[#This Row],[Open]],(Table1[[#This Row],[Close]]>=Bendras!$J$1)),AND((Bendras!$J$1<=Table1[[#This Row],[Open]]),(Table1[[#This Row],[Close]]<=Bendras!$J$1))),TRUE,FALSE)
this generated an additional column with TRUE and FALSE values which i counted with:
=COUNTIF(Table1[T/F],TRUE)
and got the answer.
so now then preparations are ready i need to make a function which would for example if the number i was searching was in 10th and 45th rows find the MAX/MIN values of Close column between those rows(hope i made my self clear)
this is how i was hoping to do that : first of all make a new array of all cell addresses from "Close" column which were "TRUE" from the first function i wrote and when do w/e i like with those cell addresses in other functions.

My co-worker created a function that would calculate the standard deviation according to whatever range is selected by the user.
I was hoping to add an if statement to the formula but am getting a #value! error.
coworker's function:
Function volatility(r As Range, Optional scl As Double = 252) As Double
Dim lr() As Double
rws = r.Rows.Count
ReDim lr(1 To (rws - 1)) As Double
Dim variance As Double
[code]....
What I'd like to do with the function:
=volatility(IF((YEAR(A8:A1036)>=K3)*(YEAR(A8:A1036)

I have a column of data with 2 possible values, "H" or "A". The second column contains numbers (unsorted).
How do I write the VBA code to return the Highest number, where the first column is 'H' ?
Eg.
Location Attendance
H 25365
A 17436
A 47252
H 15494
A 37578
H 17549
H 28756
A 59756
This would need to return 28756.

I am very proficient at Excel/VBA and have a question about custom/user-defined functions that may be a little more advanced. I understand how to write custom functions and access them through the user-defined functions menu, but I would like to be able to include my function in an add-in that users could simply add, and then access the function via the 'Fx' box at the top of Excel, like they would any other built-in function, instead of having to go to the user-defined functions menu. I guess what I am looking for is how to add 'built-in' functions and not user-defined ones. I just want the user to start typing '=customFunction(' and have the parameters pop-up in tool-tip form, like any Excel built-in function would.

I have a calendar I have developed that highlights the current date and opens by default to the current month. Each worksheet is a seperate month. The current date highlighting is written with a public macro and the opening to current month is a private macro. The problem comes when this workbook is shared and the other users have to agree to accept my macro because of security. I would like to bypass that requirement and just have the workbook stand alone without the permission.

I have a custom function that will tell me which quarter it is based on a date entered into a cell. It works except if the cell is empty is still returns the last Case but not my Case else. If the cell is blank I wanted the function to not return anything.
Function QuarterMonth(InputDate As Date)
Dim MonthNumber As Integer
MonthNumber = Month(InputDate)
Select Case MonthNumber
Case 1
QuarterMonth = "Q1 - 13"

Basically i want to use a UDF to count cells in a range of a certain colour.
But i want to make it easy for the user to be able to change the colour the function counts, so i thought i could ask them to colour the cell in which the function is written.
Is there a way to tell the function to pick up the Interior.ColorIndex of the cell it is written in?
Use Application.caller.interior.colorindex

I am trying to use the AutoFilter/Custom function in Excel (it is available under the Data Menu). It offers me two conditions/criteria that I can apply using and/or. For eg:
Filter:
does not begin with - 3
and / or
does not begin with - 9.
I want to add a third 'and' criteria .. is it possible, and if so, how?
The column that I am trying to filter has numbers formatted as text.

A custom function as shown below is not reading in the value of the parameter Ttorefinance which is an Excel cell value (actually a link in the spreadsheet). Eg when Ttorefinance cell value is 13, the function reads in 0.

I have created an addin (myAddin.xla) with custom functions in it. In a given cell, my funtion would look something like "=myCustomFunction(A1, B5)".
Periodically, while I'm working with the spreadsheet, I'll do something to a cell and the formulas in all the cells which used a custom function immediately get reset to something along the lines of "=C:...Application DataMicrosoftAddInsmyAddin.xla'!myCustomFunction(A1, B5)". The reset function also causes the function not to work properly and I get a "#NAME?" error in the cell.
I haven't yet figured out what sequence of actions causes the reset (it happens infrequently, but often enough to be a major problem) but it happens while I'm working with the document (i.e., it doesn't seem to be linked to saving/closing/reopening/etc). After I notice the reset, if I go to each cell that uses a custom function and delete everything from "C:... to myAddin.xla!" in the formula bar and hit enter, the function works normally as before.
(Technically, my Windows XP Pro system uses synchronization with a server at work, so the file path is not "C:...Application DataMicrosoftAddInsmyAddin.xla'!" but rather "\myServerNamemyDirectoryDocuments and SettingsmyUserNameApplicationDataMicrosoftAddInsmyAddin.xla'!". I'm not sure if this reset error has anything to do with being connected to the server or not, but figured I'd mention it anyway.)

Actually, I've created the user defined function (UDF) to interpolate (both linear and bilinear). It's just, I keep getting this annoying error that says "A value used in the formula is of the wrong data type." But here's the kicker...I converted the UDF into a subroutine for trouble shooting, and I was able to step through the entire code and get the correct output.
Function itcinter(efpd As Single, pwr As Single) As Variant
Dim rnge, mtrnge As Range
Dim w, x, y, z, xx, yy, b As Single
Dim scenario, a As Integer
Dim J As Variant
scenario = Worksheets("Input").Range("B1").Value
pwr = pwr / 100#
If (scenario = 1) Then
Worksheets("ITC").Select
'Make table into a range for VLookUp
Set rnge = Worksheets("ITC").Range("A3", [A3].End(xlDown).End(xlToRight))
Set mtrnge = Worksheets("ITC").Range("A3", [A3].End(xlDown))
'If the given value does not match a table value exactly

I have a simple function defined in one of my worksheets (Sheet1):
Function AddFuel(fuel As String)
MsgBox fuel
End Function
How would I be able to call this from a form button event?
Private Sub CommandButton1_Click()
Sheet1.AddFuel(TextBox1)
End Sub
Everytime I try running this code I receive the error: Run-time error '1004'; Application-defined or, Object-defined error. I've even tried Application.Run("Sheet1.AddFuel", TextBox1) but still no luck. I think this is a pretty common question but I couldn't find any answer to it on the forums.
