On Error GoTo Err_Command83_Click
Dim stDialStr As String
Dim PrevCtl As Control
Const ERR_OBJNOTEXIST = 2467
Const ERR_OBJNOTSET = 91
Const ERR_CANTMOVE = 2483
Set PrevCtl = Screen.PreviousControl
If TypeOf PrevCtl Is TextBox Then
stDialStr = IIf(VarType(PrevCtl) > V_NULL, PrevCtl, "")
ElseIf TypeOf PrevCtl Is ListBox Then
stDialStr = IIf(VarType(PrevCtl) > V_NULL, PrevCtl, "")
ElseIf TypeOf PrevCtl Is ComboBox Then
stDialStr = IIf(VarType(PrevCtl) > V_NULL, PrevCtl, "")
Else
stDialStr = ""
End If
Application.Run "utility.wlib_AutoDial", stDialStr
Exit_Command83_Click:
Exit Sub
Err_Command83_Click:
If (Err = ERR_OBJNOTEXIST) Or (Err = ERR_OBJNOTSET) Or (Err = ERR_CANTMOVE) Then
Resume Next
End If
