Recently, I had prepared a java applet for my browser. I wanted to know is there somehow I could create a script that could be distributed and the applet could be embedded in any website?
View 4 RepliesI had came acroos an open source a java applet. I wanted to know is there somehow I could create a script that could be distributed and the applet could be embedded in any website? I have been able to inject jquery and JS scripts into websites by placing a tag pointing to a Javascript file and placing it in the header of the page but I don't know how a java applet can be injected?
View 1 RepliesI have a need to integrate a third-party Java applet into a custom web part I wrote for SharePoint 2007. The web part simply loads a user control I created that contains the bulk of the functionality, and that's where the applet will go. I added it to my user control project and it works fine outside of my SharePoint environment.
I installed the updated web part onto my MOSS 2007 development site and the part's page loads fine. The applet is triggered by clicking a link button on the page, which runs some client-side JavaScript to start it. The problem is nothing seems to happen when I click the link. No error messages appear, and the stuff the applet is supposed to do never occurs (it's for doing file transfers via FTP). I have the .jar file as an embedded resource in my user control DLL, which is deployed to the bin folder, and SharePoint fully trusts this DLL.
I used Firebug to step through the initialization code and I saw an HTTP GET that failed with a message about not being authorized, but it didn't give any details and I'm not positive it was related to the applet. Is there anything special I need to do to make the applet work? Or am I going about this the wrong way?
EDIT: The problem turned out to be the .jar file for the applet couldn't be found. SharePoint is clearly doing something different here, and I need to find out what. Can Java applets be used within a SharePoint site? This question suggests they can, but in that case a Page Viewer web part was used, which isn't going to really work for me.

View 1 RepliesI have created a Java Applet that will be used in IE to print images from a remote server. I load the applet in a new popup window from my main web page and it prints fine, but it locks up the new popup browser window while it is printing. When the print job is complete the popup window becomes responsive again. The main browser window remains functional during the printing. Is there something I can do during the printing process to cause it to yield so the popup does not lock up?

I have an aspx page with a java applet. At the end of the execution, the applet navigates to another aspx page, in which there is a button that gives the possibility to execute the applet again. I would like this second page to reload every time the applet calls it, but unfortunatelly this doesn't happen. If I start from the applet's page, all works fine; but if I call the applet's page from the other one, when the applet redirects to this second page the load event does not fire. Probably the code could be clearer, so this is it:
Dummy.aspx

Dummy.aspx.vb

In one website I am working on we're using a java applet in 2 places: the 1st one in a public area where it works just fine and one in a protected folder where it just doesn't work. The protection is performed with forms authentication. The error is shown below. Any clue ?

I am trying to write an asp.net webpage which contains an applet. Everything works fine when I run this in a development folder, but when I move it to the IIS web server public folder it doesn't work anymore. I don't get any error message. The browser doesn't repaint the applet area Here is the source code:
//web page
<script src="http://www.java.com/js/deployJava.js"></script>

var attributes = { code:'ImageApplet.class', archive:'ImageApplet.jar', width:864, height:1000} ;
var parameters = {jnlp_href: 'image-applet.jnlp'} ;

add("South", jumbleButton); }
I want to fetch a web page from a ASP.NET site that is only accessible from within a session. I'm using Apache HttpClient. I first open the main page of the site, then I search for the link to the "goal" page, and then I fire up a GET request for the "goal" page. The problem is that when I get the response for the second GET request, I always get the same (first) page. If I open the site with Firefox or Google Chrome I get the "goal" page.
From the first response from the server I get the following headers:
HTTP/1.1 200 OK
Date: Sun, 12 Dec 2010 19:03:56 GMT
Server: Microsoft-IIS/6.0
Platform: Mobitel Pla.NET
Node: 4
X-Powered-By: ASP.NET
X-AspNet-Version: 1.1.4322
Set-Cookie: ASP.NET_SessionId=0vpgd055cifko3mnw4nkuimz; path=/
Cache-Control: no-cache, must-revalidate
Content-Type: text/html; charset=utf-8
Content-Length: 7032
I inspected the traffic with WireShark and all headers look OK. I send the correct cookie back to the server on the second GET request.
I'm using Apache HttpClient. I have only one instance of DefaultHttpClient and I reuse that for the second request. I have BROWSER_COMPATIBILITY Cookie Policy.
I'm looking for a way to access a Java API from both a Java console application and an ASP.Net application.In short my Java API exposes a series of methods for dealing with invoices. All of these methods are essentially commands e.g.
GenerateAllInvocies
GenerateInvoiceNumber
PrintAllInvoices
PrintInvoiceNumber
All methods will interact with the database. I had believed Web Services was going to be my means for interop. But I have since been made aware of Java Stored Procedures in Oracle.
I got asked to write a java application for my company. I'm a seasoned .Net developer so this is all new ground to me.My task is to produce an invoicing application that has several high level tasks such as:Build single invoiceBuild all invoicesMy company want to be able to call these tasks from a java console application - passing in relevant commands and parameters to invoke the tasks. They also want to be able to invoke the same code from an ASP.NET application.
View 2 RepliesI created a website using VS2010. When I run the website using built-in web server, everything works fine. The website recognizes javascript and aurigma uploader. When I publish the website to local folder and tried to access using IIS 5.1 on local pc,

I am using a third party applet which enables a user to paste a screen shot into it and it posts the file data to an upload page. I am pretty new to asp.net (VB) and wondered if I could use a Generic Handler to read the post data and save the file to disk or just a normal web form to do this? All the examples I have received with the applet are in php of which i have had no experience coming from a Classic ASP background.
View 2 RepliesI have a web user control that actually takes a zipcode and based on that brings all the store locations. I am using this contol on couple of places. That works, but I have set of html pages and on one of them I have to setup the same functionality where user inputs zipcode and store locations are displayed to him/her.My question, Can I use that web user control as an applet on my html page without writing html markup and get post methods to achieve the same functionality?
View 1 Repliesi trying to inject js to page (to tags) by using ihttpmodule.but js isn't injected.

I have a server control that needs to programmatically inject a JavaScript reference into the page. It is to reference Microsoft's Bing map control which requires &s=1 to be appended to the script URL for use over SSL. The problem is that the .NET Framework encodes the attributes and changes the & to an & (verified with Reflector). At some point after that the & is removed altogether.
Desired script tag:
<script type="text/javascript"
src="https://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1">
</script>
Attempt 1:
var clientScriptManager = this.Page.ClientScript;
if (!clientScriptManager.IsClientScriptIncludeRegistered(this.GetType(), "BingMapControl"))
{
clientScriptManager.RegisterClientScriptInclude(
this.GetType(), "BingMapControl",
"https://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1");
}
Attempt 2:
HtmlGenericControl include = new HtmlGenericControl("script");
include.Attributes.Add("type", "text/javascript");
include.Attributes.Add("src",
"https://ecn.dev.virtualearth.net/mapcontrol/mapcontrol.ashx?v=6.2&s=1");
this.Page.Header.Controls.Add(include);
Consider this abstract class
public abstract class Foo
{
public Injectable Prop {get;set;}
}
i have an application that i want to enhance and simultaneously refactor for simplicity.
I have over 100 classes that call some same stuff (e.g Class Injectable) and i am thinking that this behaviour can be abstracted and set to a base class, and everybody will inherit from this base class so as to remove copy/paste code.
However, i want to avoid copy/paste code in the spring configuration file by defining an Injectable object and then define a child object foreach and every class that inherits from Foo.
I am looking for a way to set the abstract class's properties and then all child elements to automatically get them via configuration. I want to avoid to make the abstract class like this:

I would like to create a custom action filter attribute that adds a value in the HttpContext items that would be accessible during model binding.
I have tried to add it in the OnActionExecuting but it that seems the modelbinding is exectued before the filter. Maybe there's a method in the modelbinder that I could override that will be fired after the filter and use the value injected by my filter.
What I want to do, is to inject a validation context (the library I use for validation supports context, it is nvalid.net (www.nvalid.net) I would like to be able to place an attribute such as
[ValidationContext("Prevalidation")]
on my actionresult method, so that the validation that occurs in my custom model binder could know which context to use when doing the Validation. That's why I can't simply make a custom model binder.
I have a tricky problem and I'm not sure where in the view rendering process to attempt this. I am building a simple blog/CMS in MVC and I would like to inject a some html (preferably a partial view) into the page if the user is logged in as an admin (and therefore has edit privileges).
I obviously could add render partials to master pages etc. But in my system master pages/views are the "templates" of the CMS and therefore should not contain CMS specific <% %> markup. I would like to hook in to some part of the rendering process and inject the html myself.
how to do this in MVC? Where would be the best point, ViewPage, ViewEngine?
Say I got this .aspx:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="MyPage.aspx.cs" Inherits="MyPage" %>
<script type="text/javascript">
//<!-- I want to inject a JSON string here, which is generated per side-request -->
function doStuffToMyData(){
// .....
}
</script>
how I can inject a JSON string here? I got no problem generating the string, or parsing it in the browser..
It could be there's an easier way to do this? I basically want to manipulate the looks of the side, depending on changes to this data, so I figured it would be easiest to have the data as a JSON string.
I have a simple, but probably common problem on how to inject HTML inside an ASP.NET MVC master page. I have a google analytics tracking code that sits on my master page. The code looks like this:
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXX-1']);
_gaq.push(['_trackPageview']);
// need to inject ecommerce code here
(function () {
// google analytics code here
})();
I'm using ecommerce tracking and I want to inject the "cart" information in side this HTML on the receipt page (and ONLY on this page). So I do something like this:
var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXX-1']);
_gaq.push(['_trackPageview']);
<% if(ViewData["googleanalytics"]!=null) {%>
<%= ViewData["googleanalytics"] %>
<% } %>
(function () {
// google analytics code here
})();
Then in the controller, I have code that looks like this:
[HttpGet]
public ActionResult Receipt()
{
var receipt = // get receipt model
// get google analytics javascript. This function pulls
// the data from the receipt model
ViewData["googleanalytics"] = GetAnalyticsInfo(receipt);
return View(receipt);
}
I currently work on an in-house 'CMS' that is fairly old. It has one 'content' field where the html of a CKEditor is saved and presented to each content page.
What I would like to do is be able to replace some special tags with the output of a control. So for example:
The content string would be
[Code]....
Then, when rendering the page, replace the '[%LatestNews(to=2010/01/01)%]' with the result of a user control. The user control may contain a asp:Repeater control or something that lists the required content.
I have an Html Form that I want to set focus to when the page loads. What I have done is coded the Site.Master to run a javascript function on page load. That js function retrieves a hardcoded form name from the DOM and, if found, sets focus to an input field in that form.

I have a httpmodule that contains a property.
The httpmodule is used in my web application. I want to set the property in the httpmodule when my application starts and not have the overhead of setting it everytime the module is called.
The value for the application is read from my app settings in the web.config.
The httpmodule resides in a seperate dll to the web application.
So I want to inject/set the property from my web application on application start.
