Class: FormPos in Category Microsoft Visual Basic 6 : Forms from Total Visual SourceBook

A form class to position a form on a screen in VB6.

Easily save a form's position to the Windows registry, then restore it to its previously saved position. You may also center a form or move it to a specified location. This class uses the Windows registry location based on the specified RegistryPath and RootKey properties.

Procedure List

Procedure Name

Type

Description

(Declarations) Declarations Declarations and private variables for the CFormPos class
Form Property Get a pointer to the form that was previously assigned to this property
RegistryPath Property Get the current value of the RegistryPath used for form position entries in the registry (defaults to SOFTWARE\ plus the value of App.Title)
RootKey Property Get the current value of the RootKey used for the form position entries in the registry (defaults to fprkHKeyLocalMachine, or the "HKEY_LOCAL_MACHINE" root key hive of the registry)
SubKey Property Get the current value of the SubKey used for the form position entries in the registry. If not supplied, or set to "", the entries are stored in the root of the key indicated by the RegistryPath property.
Class_Initialize Initialize Set initial values to defaults which may be overridden with property settings
Class_Terminate Terminate Release resources used by the class
CenterForm Method Centers the form on the screen
RestoreForm Method Restores the form to the last-saved position stored by the SaveForm method. Use the fForceVisible argument to handle the case where the form position was saved at a high resolution, but the user then changed to a low-resolution.
SaveForm Method Saves the current position of the form to the Windows registry. This method stores the form's current Left, Top, Width, and Height values, along with its current WindowState property, to the Windows registry. The location where this value is saved is determined by the RootKey, RegistryPath and SubKey properties of the class.
RegistryGetKeyString Private Get a string value from the system registry
RegistrySetKeyValue Private Set a key value

Example Code for Using Class: FormPos

' Example of the CFormPos class
'
' To try this example, do the following:
' 1. Create a new form.
'    Leave the form's StartupPosition property set to 3 - Windows Default
' 2. Paste all the code from this example to the new form's module
' 3. Run the form. If the form's previous position was saved, it is restored on open.
'    When the form is closed its position is saved.

' In the Declarations section of the form define the variable
Private mFormPos As CFormPos

Private Sub Form_Load()

  ' Instantiate variable
  Set mFormPos = New CFormPos

  ' Assign current form to the Form property of the object
  Set mFormPos.Form = Me

  ' Assign alternative value to the AppName property
  mFormPos.RegistryPath = "SOFTWARE\FMS\Test CFormPos"
  mFormPos.SubKey = "Form Positions"

  ' Restore to previously saved locations. If not previously saved, then simply center the form
  If Not mFormPos.RestoreForm Then
    mFormPos.CenterForm
  End If

End Sub

Private Sub Form_Unload(Cancel As Integer)

  ' Save current position for next time
  mFormPos.SaveForm

End Sub
