Help use the same function on multiple command buttons

Seemingly simple. I have a form with 10 Command buttons, they all are used to Browse for a dir path. Each button returns the choosen dir to it's associated text box. So this is what I want, rather than copy the code for each button(10) I'd like to call a Public Function from each button, therfore only writing the code once.

Here is my problem. How/What variable do I pass to the function, and how do I get it to return to the proper textbox? Have I confused you? Here is my Code for the Browse Button:

Option Explicit

Private Type BrowseInfo
pIDLRoot As Long
pszDisplayName As Long
lpfnCallback As Long
lParam As Long
iImage As Long
End Type
Const BIF_RETURNONLYFSDIRS = 1
Const MAX_PATH = 260
Private Declare Sub CoTaskMemFree Lib "ole32.dll" (ByVal hMem As Long)
Private Declare Function lstrcat Lib "kernel32" Alias "lstrcatA" (ByVal lpString1 As String, ByVal lpString2 As String) As Long
Private Declare Function SHBrowseForFolder Lib "shell32" (lpbi As BrowseInfo) As Long
Private Declare Function SHGetPathFromIDList Lib "shell32" (ByVal pidList As Long, ByVal lpBuffer As String) As Long

Public Function Browse()

On Error GoTo Err_Browse

Dim lpIDList As Long
Dim udtBI As BrowseInfo
Dim iNull As Integer
Dim sPath As String

lpIDList = SHBrowseForFolder(udtBI)

If lpIDList Then
sPath = String$(MAX_PATH, 0)
'Get the path from the IDList
SHGetPathFromIDList lpIDList, sPath
'free the block of memory
CoTaskMemFree lpIDList
iNull = InStr(sPath, vbNullChar)
If iNull Then
sPath = Left$(sPath, iNull - 1)
End If
End If

Me.txtDir1 = sPath 'This is where I need the help

Exit_Browse:
Exit Sub

Err_Browse:
MsgBox Err.Description
Resume Exit_Browse

End Sub

Here I would call the Function

Private Sub Browse1_Click()
Browse
End Sub

The Browse Buttons a labled Browse1-10
The Text Boxes are labled txtDir1-10

The code is marked with this caption where I belive I need the help
'This is where I need the help

I know I need to pass variables but how?

TIA

From the sound of it you would be best off making a control array of buttons and a corresponding control array of text boxes. To make a control array, try to copy and paste a control (ie a textbox, label, button, listbox, you get the idea) and it should ask you if you want to create a control array. Click yes and keep pasting as many controls as you need.

The benefit of this is two-fold: Firstly you can refer to each element in a control array by controlname(index) where index is an integer which corresponds to the index property of one of the controls. This means you can use the index for the button that gets clicked as the index for the textbox it applies to. Secondly, all controls in a control array share their code, so you only have to write the code once into the cmdButton_click event and it will use that code for all of the buttons.

Oh but if for some reason you don't want to use control arrays, then to answer your question simply pass in a reference to an object of type TextBox:

Private Sub cmdButton_click

Dim theBoxToBePassed As TextBox
Set theBoxToBePassed = Text1
DoStuff theBoxToBePassed

End Sub

Private Sub DoStuff(theBox As TextBox)

'here you can refer to the textbox like this:
theBox.Text = "That command button affects this text box"

End Sub
