QUESTION
i am having a problem clearing a date text box. When ever i do a post back the date returns. I have tried multiple methods to clear the date the main one is calling into the in house library for the date control adding a clear button that clears it server side. I have also tried using the same clear button to clear it client side using JavaScript. No matter what method i use the original date returns to the box. This is causing validation errors when saving the page.
This is the original boxes with the dates in
If i clear the start date it disappears
When i clear the end date the start date returns
This is how i clear the dates
...ANSWER
Answered 2021-Jun-03 at 14:02As the text box, calendar extender and tool tips are bundles up within a single control when setting the value within the calendar extender's selected value it would return it on post back, as this is not required as the textbox will hold the current value it was easier to clear the selected value from the calendar extender or better just omit setting it at all during the page build action. I removed it completely and solved the problem of the original value been retained.
QUESTION
So I did a lot of digging around the internet, and I have been unable to come up with the answer to my problem. My goal is that I want to print any errors that are logged to the console into a database. However, I have gone far enough into my project that it would be a pain to go back into my try...catch...
blocks and edit them with an error extender, or to just create my own function in the catch area.
I wanted to know: is there a specific way to create an error interception in NodeJS? I mean, I assume that whenever an error is logged to the console, the code fires some sort of event, and I guess I am looking for something like:
process.on(error, async (e) => { // my code here })
Is that at all possible? Is there a module that will allow me to do this? For context, I am running the latest version of Node/NPM on a headless Ubuntu 18.04 server, and am using pm2
to control my program processes.

I have a user control that contains a confirm button extender and a modal popup extender. It looks like:
...ANSWER
Answered 2021-May-02 at 15:56When selected item changes, your javascript code is trying to click on btnConfirmSelection
button. The problem is, you have AutoPostBack="true"
. So it is posting back the page at the same time. For that reason it looks like the modal is closing down as you get the page again from server.
I haven't tested your code but I'd suggest to set AutoPostBack="false"
and check if that fixes the problem.

I have created a simple line chart visual using the d3.v4.min.js framework.
The visual looks like:
As you can see my problem is the alignment of the lines and their dots with the x-axis.
Below you can find the code implemented. I would like both lines to start off from Germany and not from the y-axis. I am guessing that due to a categorical and not numerical x-axis, javascript cannot distinguish the starting point so it paints the lines from the y-axis.

QUESTION
I am trying to use the Aspectj compiler ajc in a modular (OSGi setting). The standard way ajc seems to be used is to take aspects & java code and turn it into one a JAR with all classes and resources in the -inpath
, -aspectpath
, and -sourceroots
.
I am trying to weave aspects an OSGi executable JAR from bnd. This executable jar contains a set of bundles that need to be woven. However, in a modular system, the boundary is quite important. For one, the manifest often contains highly relevant information to that bundle or one of the many extenders. Flattening all the classes into a big blog won't work.
I am therefore weaving each bundle separately. However, then the output is cluttered with the aspects. I'd like to import these to keep the aspect modules proper modules. However, using the annotation programming model, I notice that ajc is modifying the aspect modules, so I need to rewrite those as well. This is fine, but since I weave each bundle separately, I have the question if the weaving of the aspect could depend on what gets other modules woven? That is, does the modification of the annotated aspect depend on the classes that it is woven in?
The other issue is what happens to resources with the same name? Since my -inpath
is only one JAR (the bundle), I notice I end up with the correct manifest (META-INF/MANIFEST.MF) in the output. However, if the -inpath
consists of many bundles, what will the manifest be? Or any other resource that has the same path and thus overlaps?
Last issue is external dependencies. I understand acj wants to see the whole world and include this whole world into the output JAR. However, I must exclude external dependencies of a bundle. Is there a way to mark JARs as: use, but do not include. A bit like the maven 'provided' scope?
Summary:
- Does the modification of an @Aspect annotated class depend on the targets that is applied to?
- Can I compile the @Aspect annotated classes into separate JARs?
- How to handle the external dependencies that will be provided in the runtime and thus must be excluded from the output JAR.
- What are the rules around overlapping resource paths in the
-inpath
and-sourceroots
?
UPDATE In the mean time I've made an implementation in Bndtools.
...ANSWER
Answered 2021-Mar-03 at 01:56Does the modification of an @Aspect annotated class depend on the targets that is applied to?
If you want to be 100% sure you have to read the AspectJ source code, but I would assume that an aspect's byte code is independent of its target classes, because otherwise you could not compile aspects separately and also not build aspect libraries.
Can I compile the @Aspect annotated classes into separate JARs?
Absolutely, see above.
How to handle the external dependencies that will be provided in the runtime and thus must be excluded from the output JAR.
If I understand the question correctly, you probably want to put them on the class path during compilation, not on the inpath.
What are the rules around overlapping resource paths in the
-inpath
and-sourceroots
?
Again, probably you have to look at the source code. If I was you I would simply assume that the selection order is undefined and make sure to not have duplicates in the first place. There should be Maven plugins helping you with filtering the way you want the result to be.
bndtools seems to have close ties to Eclipse. So does AspectJ as an Eclipse project. Maybe you can connect with Andy Clement, the AspectJ maintainer. He is so swamped with his day-time job though, he hardly ever has any free cycles. I am trying to unburden him as much as I can, but OSGi is one of my blind spots and I hardly know the AspectJ source code. I am rather an advanced user.

QUESTION
ASP.NET 4.7.2 Web Forms c# VS 2019
I am trying to use a modalpopupextender
to prompt for new data for foreign key fields. Like the form itself, the MPE is built on the fly in code -- in this case the click handler for the hidden button that the Javascript fires off to build and show the MPE.
I read every single article on SO and the ASP forums and tried everything I saw there. No joy. I get the popup perfectly. Hitting OK closes the popup, but never fires the OK Event.
Here is the code:
...ANSWER
Answered 2020-Dec-23 at 06:49You can't add a server side button or inject a server side button into the page DOM.
When you drag a asp.net button onto the form, BOTH the "mypage.cs" and mypage.desinger.cs ARE updated. The wire up of the button occurs at design time, and you would have to modify mypage.desinger.cs ALSO and ADD a button event stub.
So you can't do this.
A compromise would be to also add some js and have that HTML button execute a .click() method of a hidden asp.net button you drop into that page (that would give you the post back, and the running behind of a separate button event code stub.
This event resolution occurs at compile time - not at page render time. You have to drop that button onto the page.
I suppose you could adopt a standard that you always place right below that "div" on the page the button (hidden with style=none. And then as noted, have your injected code along with some js execute a click on the hidden button. Or just have the js button code execute a __doPostback("some value") and pick this up in the page on-load event, and then call the routine (function) from on-page load event.
I think better would be to use a jQuery.UI dialog, as that dialog CAN say load + use another different web page into a “div” on the existing page. So you layout, make, and create the nice looking popup form as a separate web page. jQuery is able to remove the “form” and additonal tags out of that page load, and then inject it into the existing page. (that code would be rather hard to re-produce). so jQuery.UI is able to pop up that separate page. however, the buttons on that loaded page (into that div) of course can't really run any code behind in the current page. However, the buttons CAN run local js in the current page. Thus the actions of this injected page would be local to each page. But the popup would not be directly calling a code behind stub.
Now, to adopt jQuery.UI, then you also have to of course adopt jQuery. So that is two extra libraries you need. (but, jQuery you likely already have).
However, I suppose the whole point of using the ajax toolkit is to avoid jQuery.ui in the first place. To be fair, before jQuery.ui came along, that tool kit was REALLY impressive, and gave asp.net folks a REAL leg up on the competition. (and it tends to be MUCH less wiring up then say using jQuery.UI
So the AjaxToolkit in its heyday was impressive. Now, it of course showing its age, but I still use the kit, and this is especially the case for the AjaxFileUploader. And yes I do use the popups – even to this day. However, I find now that jQuery.UI dialogs are more flexible, and would be better in this case (because you want a on-the fly setup).
Also, having code behind buttons in even the jQuery.UI dialog, or in this case the ajax popup? Well, only the action button can run code behind. The cancel button of course will just dismiss the dialog. However, any button in the dialog that WILL run code behind? Well, that's ok, since you have a page post back, and it actually the page postback that BLOWS out the dialog anyway.
