Microsoft Access provides no built in support to scale a form's size tomatch the current screen resolution. A form that you design on a computerwith a video driver resolution of 1024x768 (Super VGA) may appear too largeon computers running at 640x480 (VGA) resolution. A form that you designusing 640x480 resolution may appear too small on computers running at1024x768 resolution.
The following information describes where you can obtain two Access Basicfunctions, glrScaleForm() and glrResizeForm(), that you can use todynamically scale and size a form. The glrScaleForm() function can becalled from the Open event of your form to scale the size of a form to thecurrent screen resolution when the form loads. The glrResizeForm() can becalled from the Resize event of the form to automatically move and size thecontents of a form proportionally to fit the new dimensions of the formwindow.
glrScaleForm()The glrScaleForm() function can be called from the Open event of your formto automatically scale the form to the current screen resolution.
Syntax: Function glrScaleForm (frm As Form, intX As Integer, intY As Integer) frm: form to be scaled intX: horizontal resolution at which the form was designed intY: vertical resolution at which the form was designed Example: Sub Form_Open (Cancel As Integer) Dim RetVal RetVal = glrScaleForm(Me, 1024, 768) End Sub
glrResizeForm()The glrResizeForm() function can be called from the Resize event of yourform to automatically move and resize the contents proportionally to fitwithin the new form window size.
Syntax: Function glrResizeForm (frm As Form, fDoResize As Variant) frm: form to resized fDoResize: boolean value indicating if the form should be resized or the information tracked Example: Sub Form_Resize () Dim RetVal RetVal = glrResizeForm(Me, True) End Sub
How To Obtain The glrScaleForm And glrResizeForm FunctionsThe glrScaleForm() and glrResizeForm() functions, written by Ken Getz, arepublished in the following book:
Microsoft Access 2 Developer's Handbook. Ken Getz, Paul Litwin, Greg Reddick. Sybex: 1994 ISBN: 0-7821-1327-3
Discussion of these function begins on page 506, chapter 8, "ScreenResolution and Distributing Forms." The functions are included in the file_Glrfile.exe on the accompanying companion disk. This self-extracting,compressed file contains the file _Chapter.exe, another self-extracting,compressed file, which contains the database CH8.mdb. The formfrmTest1280x1024 in CH8.mdb demonstrates the use of these functions. Checkthe "Enable Automatic Resizing?" check box in the upper-left corner ofthe form frmTest1280x1024, and then resize the form window to see theglrResizeForm() function work.
These functions were originally published with a column in Smart Accessmagazine.
