Call a VBA Function into a Sub Procedure

Question

I know this is a simple question for someone out there  but I have never really used function module at all because I did not understand what they were   So I have a whole bunch of things I can use this for  cut down on redundancy   but I want to know how I call into a sub  like a button click  procedure from a form   I tried this     Sub Command Click       Call  pptCreator  End Sub   I know that is pretty bad  but I have no idea how to bring this into a procedure

To Add a Function To a new Button on your Form   and avoid using macro to call function  After you created your Function  Function MyFunctionName    and you are in form design view   Add a new button  I don t think you can reassign an old button - not sure though    When the button Wizard window opens up click Cancel   Go to the Button properties Event Tab - On Click - field   At that fields drop down menu select  Event Procedure   Now click on button beside drop down menu that has     in it and you will be taken to a new Private Sub in the forms Visual Basic window   In that Private Sub type   Call MyFunctionName It should look something like this  Private Sub Command23 Click        Call MyFunctionName  End Sub   Then just save it

Calling a Sub Procedure     3 Way technique  Once you have a procedure  whether you created it or it is part of the Visual Basic language  you can use it  Using a procedure is also referred to as calling it   Before calling a procedure  you should first locate the section of code in which you want to use it  To call a simple procedure  type its name  Here is an example   Sub CreateCustomer       Dim strFullName As String      strFullName    Paul Bertrand Yamaguchi   msgbox strFullName End Sub  Sub Exercise       CreateCustomer End Sub   Besides using the name of a procedure to call it  you can also precede it with the Call keyword  Here is an example   Sub CreateCustomer       Dim strFullName As String      strFullName    Paul Bertrand Yamaguchi  End Sub  Sub Exercise       Call CreateCustomer End Sub   When calling a procedure  without or without the Call keyword  you can optionally type an opening and a closing parentheses on the right side of its name  Here is an example   Sub CreateCustomer       Dim strFullName As String      strFullName    Paul Bertrand Yamaguchi  End Sub  Sub Exercise       CreateCustomer   End Sub   Procedures and Access Levels  Like a variable access  the access to a procedure can be controlled by an access level  A procedure can be made private or public  To specify the access level of a procedure  precede it with the Private or the Public keyword  Here is an example   Private Sub CreateCustomer       Dim strFullName As String      strFullName    Paul Bertrand Yamaguchi  End Sub      The rules that were applied to global variables are the same       Private  If a procedure is made private  it can be called by other procedures of the same module  Procedures of outside modules cannot access such a procedure       Also  when a procedure is private  its name does not appear in the Macros dialog box      Public  A procedure created as public can be called by procedures of the same module and by procedures of other modules       Also  if a procedure was created as public  when you access the Macros dialog box  its name appears and you can run it from there

Here are some of the different ways you can call things in Microsoft Access  To call a form sub or function from a module The sub in the form you are calling MUST be public  as in  Public Sub DoSomething     MsgBox  quot Foo quot  End Sub  Call the sub like this  Call Forms  quot form1 quot   DoSomething  The form must be open before you make the call  To call an event procedure  you should call a public procedure within the form  and call the event procedure within this public procedure  To call a subroutine in a module from a form Public Sub DoSomethingElse     MsgBox  quot Bar quot  End Sub     just call it directly from your event procedure  Call DoSomethingElse  To call a subroutine from a form without using an event procedure If you want  you can actually bind the function to the form control s event without having to create an event procedure under the control   To do this  you first need a public function in the module instead of a sub  like this  Public Function DoSomethingElse     MsgBox  quot Bar quot  End Function  Then  if you have a button on the form  instead of putting  Event Procedure  in the OnClick event of the property window  put this   DoSomethingElse    When you click the button  it will call the public function in the module  To call a function instead of a procedure If calling a sub looks like this  Call MySub MyParameter   Then calling a function looks like this  Result MyFunction MyFarameter   where Result is a variable of type returned by the function  NOTE   You don t always need the Call keyword   Most of the time  you can just call the sub like this  MySub MyParameter

Procedures in a Module start being useful and generic when you pass in arguments   For example   Public Function DoSomethingElse strMessage As String        MsgBox strMessage End Function   Can now display any message that is passed in with the string variable called strMessage
