Resolution Resize and Run Time Control Resize. Module for automatically resizing forms and controls with varying screen resolutions. To use it
API Declarations
' Place this code
' Resolution Resize and Run Time Control Resize.
'Module for automatically resizing forms and
'controls with varying screen resolutions. This is
'an adaptation of a Microsoft Knowledge Base
'article. The example worked as it was but half the
'code was on the form. I wanted a complete module
'to add to any app easily. To use it simply add
' "Call G_P_AdjustForm(Me)" to the Form_Load event
'and "Call G_P_FormResize(Me)" to the Form_Resize
'event. Also change the design time resolution
'values.
' I have Refered some another code
