Unanswered: Using Call Sub, but not running all of the code?
Need a bit of help.
I have two Subs, SubA and SubB.
SubA is Public
SubB is Private
SubA contains a lot of code.
SubB contains: Call SubA, and nothing else.
I need to put a line of code in SubA, that only only runs when SubA itself is run, so it doesn't occur when SubB Calls it.
Is this possible?
I've tried putting a sub-Sub, and declaring it as Private (as I would do in Java - Well, kind of anyway), but VBA won't have any of it.
Any ideas on how to sort this?
What I'm doing is using the 'dropdown' method of a combo box, it needs to be used on the 'Change' (which is SubA), but not on the 'AfterUpdate' (which is SubB). I can't put it on the 'GotFocus' event, because it's part of a tabbed form, and is no.1 on the tab priority, and I don't want it to open everytime the tab is changed as it's a multicolumn combobox, and its contents is pretty huge.
I realise I can copy and paste all the code from SubA, into SubB, whilst omitting the 'dropdown' method, but this violates best practice because it's repeating code. As there's quite a lot of it, and it's fairly complex, I don't want to have to make amendments twice all the time, and risk causing additional errors.
Any advice/solutions, please fire away...
Thanks in advance peeps!Looking for the perfect beer...

You could declare a public variable in a class module along with your code for subA, as follows...
Option Compare Database Public SubACheck As Boolean Public Sub SubA() If SubACheck = False Then MsgBox ("Code would run.") 'Code to run here Else MsgBox ("Code would NOT run.") End If SubACheck = False End Sub
Private Sub SubB() SubACheck = True Call SubA End SubHope this helps,

You can also use an optional argument :
Public Sub SubA([Other arguments (if any)], Optional Byval CalledBySubB as Boolean) If CalledBySubB = False Then ' Code would run. 'Code to run here Else ' Code would NOT run. End If End Sub
Private Sub SubB() Call SubA [Other arguments (if any)], True End SubHave a nice day!
