I am new with Esper so i am unable to solve a simple problem. All i have to do is to get the difference of current close of bar with the previous close of bar. Whats the smartest way to approach this problem in esper?
Result= CurrentBar.Close - PreviousBar.Close.
EDIT:
I am using following piece of code will this work?
select
prev(0,close) - prev(1,close) as return,
security
from
Bar.win:length(2);
The "prev()" special function.

Thanks in advance for your assistance here. I really appreciate it!!
I have built a script using the template here: https://developers.google.com/workspace/solutions/mail-merge
...And it's awesome. Working perfectly and solving a big problem for me!!
I have 2 problems I need to fix, and I need your help, please!!
Problem 1: Can I use a column (or cell reference) as a default "subjectLine" rather than it be user input each time the script is run?
Problem 2: Once Problem 1 (above) is solved, I'd like to trigger the script to automatically run every 15 minutes, continuously.
Any tips/scripts/pointers would be awesome. I am quite new to coding so have tried to dig up how to replace the user input piece of code with a default value for the subject line, but I can't figure it out. And only once this is done, can I then start to try and get code working for the second problem - so I'm stuck on both counts.
Thanks again!! Kind regards, Tom
I'm working on a DNN site that has been set up before my time here.
There's some conflict with the jQuery I believe, which prevents the modal pop up window in the attached calendar (link) events to not close properly:
http://www.sim-one.ca/NewsandEvents/calendar-of-events.aspx
I tried eliminating one script call at a time to see which one could be messing this up to no avail.
When I test this with the default theme it works like a charm.
Any ideas? Anyone came across something like this before?
Thank you!
You've got plenty of 404 errors on that page, ensure first, that files are in their place.
For example, http://www.sim-one.ca/NewsandEvents/Portals/_default/Skins/SimTwo/includes/js/jquery.listnav-2.1.js was not found. Ensure this path exists.
I agree with Anrie that your references are broken. For example, http://www.sim-one.ca/NewsandEvents/Portals/_default/Skins/SimTwo/includes/css/custom-theme/jquery-ui-1.8.9.custom.css is showing 404 but http://www.sim-one.ca/Portals/_default/Skins/SimTwo/includes/css/custom-theme/jquery-ui-1.8.9.custom.css
You can just use links like :
/Portals/_default/Skins/SimTwo/includes/css/custom-theme/jquery-ui-1.8.9.custom.css in order to fix this in skin file or use <%= SkinPath %>.
Try adding return false; on your event after calling the dnnModal.show()
SmartGWT has this property for a TreeGrid object:
employeeTreeGrid.setSelectionAppearance(SelectionAppearance.CHECKBOX);
This by default 'prepends' every nodes (including root) with checkbox.
(Just making myself clear.)
Also, I am aware of this similar solved question:
GWT tree with checkbox:How to get all checked tree items?
However, I do not seek this kind of solution..
What I'm looking for is a more efficient way, where I don't have to loop through 1000 items.
Is there any way to do this, if possible, using the widget I am using now?
If not, is there any other way, using other widget?
Thank you very much!
I think as you use SelectionAppearance.CHECKBOX you tell to the grid that the selected records are marked by the checkbox field value. So every time you check one you select a record.
You can get the set of selected records by either getSelection() method or getSelectedRecords(boolean) because of deprecation of the previuous one.
You can have a look at the code of this example of the smartgwt showcase.
This is probably jquery basics, but I can't find a solution after much googling.
How do you attach "non-events" to elements inserted in the DOM?
For events, like click, we can use live() or bind().
How would you, for instance, initialize tabs() or addClass() to a new element?
Specifically, I'm trying to get tabs() to work in the content of an ajax loaded dialog, but I think the correct solution should be applicable to any situation.
I did see a trick that involved $('body').mousemove() which did work, but that is still binding to an event and obviously a hack.
For instance, how would you get addClass() to fire on a newly inserted table row?
I mean to do this implicitly, meaning that I don't want to write out specific instructions for every event that adds nodes to the dom, I just want it to "run in the background".
Let me know if this needs clarification, I see many similar questions on SO but no answers that have helped.
EDIT: Simple example: A page calls $('a').addClass('highlight') which works on all anchors in the page. A new anchor is then added to the page dynamically by jQuery, but does not get the class added.
EDIT: I have tried all kinds of bind(), trigger() and change() methods but I'm afraid I'm barking up the wrong tree.
you need to look at livequery it will allow you to apply things to newly added elements
also if your adding the element you can do
$('body')append('<div>some content</div>').tabs();
or something like that
I know that I may contradicting your "non-event" rule here, but just by saying that you want something "triggered", you're already implying some kind of event.
In that case, may I suggest jQuery custom events? You may want to create a custom event, then trigger it manually somewhere in your code. It's not automatic (like when you add a row, BOOM, it fires™), but that's the closest thing I can think of with what you were describing.
Specifically, you may want to look at jQuery's .bind() and .trigger() methods.
The auto_complete_for dealio from script.aculo.us is great an all, but is there a way for me to selectively disable the fact that it always auto-selects the first item in the list?
The problem is that, if I want to type my own entry that is new, and novel, I don't want the first item in the list to be auto-selected. The reason is because when I TAB out of the field, it selects, and fills the text box with that first item.
I got around that, somewhat, by making the first item in the list the same as what I'm typing, but that's not perfect either, because the auto_complete list doesn't always update with every keystroke, depending on how fast I type. I've tried setting the list refresh rate to the lowest value (1 millisecond) but no go.
What I really want is an option in "auto_complete_for" that doesn't select that first item at all - the same way that Google Instant doesn't automatically select the first suggested search phrase - you have to arrow-down to select one.
Maybe I can do this via an HTML option that I'm missing?
Looking at the source, there doesn't appear to be an option for that, but I bet if you changed line 284 of controls.js to this.index = -1; it would do what you want.
Otherwise, it might be time to look for a different autocomplete widget.
If your requirements are too far away from the available plugin, then I guess there is no point in tinkering around. Its best to write your own JS code.
You might want to consider this: https://github.com/laktek/jQuery-Smart-Auto-Complete
or this : https://github.com/reinh/jquery-autocomplete
I'll add another alternative that works great with Rails 3:
http://github.com/crowdint/rails3-jquery-autocomplete
I recently implemented auto complete for more than a field for Rails 2.0.2.
The plugin I used is:- https://github.com/david-kerins/auto_complete . Not sure if it supports Rails 3.
I have also encountered issues on implementing the above scenario and have posted questions( Implementing auto complete for more than one field in Rails ; Implementing a OnClick kind of functionality and formatting wrt Rails Partial-Views ) on stackoverflow for the same, I have been lucky on getting things working for me based on my requirement.
Kindly refer to these questions, they might have relevance to your requirement.
