Windows Slideshow Gadget enhance help

Posted 03 May 2015 - 04:54 AM

Hello,

I'm posting here becauseI need your help with editing Slideshow Gadget file (Win7). Unfortunately, I've no coding experience so that's why I can't find solution for it myself. What I've dreamed for is slideshow on my desktop where I can see motivational pictures that would change once per 30 mins. Unfortunately windows gadget doesn't have such option (5 mins max) and it is too small for my needs.

I tried to edit file by myself but I couldn't recieve results I wanted.

#1 when I tried to add 30 mins option in scroll menu the program wouldn't even start.

I changed this:

var pictureArray	= new Array();
var selectArray	= new Array();
var slideTimeArray	= new Array(
	["5 " + L_SECONDS_TEXT, 5],
	["10 " + L_SECONDS_TEXT, 10],
	["15 " + L_SECONDS_TEXT, 15],
	["30 " + L_SECONDS_TEXT, 30],
	["1 " + L_MINUTE_TEXT, 60],
	["2 " + L_MINUTES_TEXT, 120],
	["5 " + L_MINUTES_TEXT, 300]);

var gMaxSecondsToShow = 300;


into this:

var pictureArray	= new Array();
var selectArray	= new Array();
var slideTimeArray	= new Array(
	["5 " + L_SECONDS_TEXT, 5],
	["10 " + L_SECONDS_TEXT, 10],
	["15 " + L_SECONDS_TEXT, 15],
	["30 " + L_SECONDS_TEXT, 30],
	["1 " + L_MINUTE_TEXT, 60],
	["2 " + L_MINUTES_TEXT, 120],
	["5 " + L_MINUTES_TEXT, 300]),
    ["30 " + L_MINUTES_TEXT, 1800]);

var gMaxSecondsToShow = 1800;
.

#2 When I tried to change size of slideshow it wouldn't fit in border --> [img]http://oi61.tinypic.com/zsoh2q.jpg[/img]

I changed

this

var maxDockedWidth	= 120;
var maxDockedHeight	= 90;
var maxUndockedWidth	= 320;
var maxUndockedHeight = 240;


and this

function undockedState()
{
	gUndockFlag = true;
	with(document.body.style)
		width=360, 
		height=280;

	with(slideshowBg.style)
		width=360, 
		height=280;
	slideshowBg.src="url(images/on_desktop/slideshow_glass_frame.png)";

	with(bar.style)
		width=112,
		height=23,
		top=220,
		left=119;

	with(pictureFrame.style)
		top=16,left=17,width=320, height=240;
		
	if(imagePathAndName != undefined)
	{ 
		scaleImageForDisplay();
	}
}


into

this

var maxDockedWidth	= 120;
var maxDockedHeight	= 90;
var maxUndockedWidth	= 640;
var maxUndockedHeight = 480;


and this

function undockedState()
{
	gUndockFlag = true;
	with(document.body.style)
		width=640, 
		height=480;

	with(slideshowBg.style)
		width=640, 
		height=480;
	slideshowBg.src="url(images/on_desktop/slideshow_glass_frame.png)";

	with(bar.style)
		width=112,
		height=23,
		top=220,
		left=119;

	with(pictureFrame.style)
		top=16,left=17,width=640, height=480;
		
	if(imagePathAndName != undefined)
	{ 
		scaleImageForDisplay();
	}
}


I would really appreciate it if you could help me solve this.
