Custom Function basic

Joe_Germany

Hello all..

I am trying to make a custom function.. I am using german Excel..
My qn is - Can we use the standard functions inside vb..

For eg, ABRUNDEN(x,y) is the function for Round(x,y)
can i use abounden(x,y) as a vb code while making the custom function..

If not is there any way we can access the standard functions while
making custom functions?

Thanks all
Joe

Look in VBA help for all functions available.

Thax Toppers..

I got the result I wanted.. My FIRST custom function.. Im happy..
See if it is usefull..

I made this to add a number of working days on a given day..

---------

Function AddWorkDays(Date_St As Date, n As Integer) As Date

Dim WeekDay_St, n_Weekends, n_Shift As Integer

WeekDay_St = WorksheetFunction.WeekDay(Date_St, 2)
n_Weekends = WorksheetFunction.Floor((WeekDay_St + n - 2) / 5,
1)
n_Shift = n_Weekends * 2 + n - 1

AddWorkDays = Date_St + n_Shift

End Function

------
say A1 is the start date and A2 is the no of working day needed..

A1: 31/08/06
A2: 5

AddWorkDays(A1,A2) will give you 06/09/06

if A2 is 1, its the same day..
If A1 is a weekend and if A2 is 1, the out put is next monday..


Hope someone can use it..
suggessions / comments are most welcome

Bye.

It also counts too many if you input a sunday date.

One more qn ..
the help for WORKDAY says that the date has to be entered with DATE
function..

If i have a date in a cell, how I can use that directly to this fn,
rather than extracting year, month and date from that & in turn use
that in the DATE function for this..

Thanks a lot..

Hi

You need Analysis Toolpack Add-In for this. A lot of other useful functions
are added too.

Thanks especially to Toppers & Bob..

Thats true.. What I wanted was the WORKDAY fn..
Since I started making this I thought I would finish this.. So I did..

Adv from WORKDAY
-----------------------------
It takes weekend input better..

DisAdv frm WORKDAY
-----------------------------
It doesnt add -ve values..


So here it is..

------------------------

Function AddWorkDays(Date_St As Date, n As Integer) As Date
Dim WeekDay_St, n_Weekends, n_Shift As Integer

WeekDay_St = WorksheetFunction.WeekDay(Date_St, 2)
If (WeekDay_St = 7) Then
WeekDay_St = 6
End If
n_Weekends = WorksheetFunction.Ceiling((WeekDay_St + n - 1) /
5, 1) - 1
n_Shift = n_Weekends * 2 + n - 1

AddWorkDays = Date_St + n_Shift

End Function

------------------------------

Now I have to see how I can make it in such a way that it can be added
as ADD-INS..

Thx again guys..

Joe
