Passing User Defined type to Sub produces "Variable Required - can't assign to this expression" Error

Here's the code

Private Type Customer
    Name As String
    Address As String
    Spending As Single
End Type

Private Sub Form_Load()
    Dim myCustomer As Customer
    myCustomer.Name = "Johnny Boy"
    myCustomer.Address = "123 Main Street"
    myCustomer.Spending = 54000.3695

    showCustomer (myCustomer)
End Sub

Private Sub showCustomer(ByRef cust As Customer)
    txtname = cust.Name
    txtaddress = cust.Address
    txtspending = cust.Spending
End Sub

You could use a class module to act as your custom data type then pass the class module.  

---- in the class mod names clsMyObject.cls ---
public Name as string
public Address as String
public Spending as Single

---- in your form or basic modules ----
  dim oMyObject as clsMyObject

'--- create an instance of my custom typs
  set oMyObject as new clsMyObject

'--- put some data in your object
  oMyObject.Name = "Tester J. Test"
  oMyObject.Address = "123 Fake St."

'--- pass it along
  Call showCustomer(oMyObject)

---- in the mod you want to pass the custom object to

private sub showCustomer(byref oTemp as clsMyObjext)

'--- use the data from the custom object.
  txtname.text = oTemp.Name

end sub

There is a bunch of info on this in the MSDN ... search for "Sharing coffee" ... there are about 3 or 4 related articles about this.

hope it helps.

This will work if you change your line:

showCustomer (myCustomer)


Call showCustomer(myCustomer)

You always have to use 'Call' when you use sub-routines, as these are different from functions that produce a value.

Hope you get it to work!
