Perhaps I need to do a little more clarification here. I do not need to format a date string. I need to et the control so that it formats the date string. The Win32::GUI::DateTime control, which is what I suspect Grid is using, can be set to use different dat/time format via the Format method. I just don't know how to access the DateTime object within the Grid Cell object so that it displays the correct format. Here is a short piece of code to demonstrate the issue: 
#!c:\perl\wperl.exe

use strict;

use Win32::GUI;
use Win32::GUI::Grid;

my $mainform = Win32::GUI::Window->new(-name=>'main',-text=>'Grid Date
+ Format Problem',-width=>810,-height=>625,-dialogui=>1);
my $grid = $mainform->AddGrid(-name=>'grid',-pos=>[25,85],-rows=>2,-co
+lumns=>3,-fixedrows=>1,-fixedcolumns=>1,-editable=>1,-size=> [520,400
+],-addstyle=>WS_VSCROLL|WS_TABSTOP);
    
    $grid->SetColumnWidth(0,100);
    $grid->SetColumnWidth(1,100);
    $grid->SetColumnWidth(2,100);

    $grid->SetRowHeight(1,30);
    
    $grid->SetCellText(0, 0, "ID");
    $grid->SetCellText(0, 1, "GVIT_DATECAL");
    $grid->SetCellText(0, 2, "GVIT_DATE"); 

    $grid->SetCellFormat(1, 1, 'yyyy-MM-dd');
    $grid->SetCellType(1, 1, GVIT_DATECAL);
    $grid->SetCellText(1, 1, "2005-07-19");
    
    $grid->SetCellFormat(1, 2, 'yyyy-MM-dd');
    $grid->SetCellType(1, 2, GVIT_DATE);
    $grid->SetCellText(1, 2, "2005-07-19");

$mainform->Show();
Win32::GUI::Dialog();

The SetCellFormat method is probably not what I need to use here but I have no idea how to make it work. After you select a date using the control, the cell will display the date in whatever your short date format is. If you change your short date format and re-run the program, it will display in the new format you set. I want to ignore the default setting for the system and set the format myself.

By the way, the code you provided doesn't work as far as I can tell. Whether I send it a date like 2005/7/19 or 7/19/2005 it returns something that doesn't look like a date to me.

But again, thanks for replying.
