  • Prevent ASP.NET from encoding strings on output

    - by Darkwater23
    How can I stop ASP.Net from encoding anchor tags in List Items when the page renders? I have a collection of objects. Each object has a link property. I did a foreach and tried to output the links in a BulletedList, but ASP encoded all the links. Any idea? Thanks! Here's the offending snippet of code. When the user picks a specialty, I use the SelectedIndexChange event to clear and add links to the BulletedList: if (SpecialtyList.SelectedIndex > 0) { PhysicianLinks.Items.Clear(); foreach (Physician doc in docs) { if (doc.Specialties.Contains(SpecialtyList.SelectedValue)) { PhysicianLinks.Items.Add(new ListItem("<a href=\"" + doc.Link + "\">" + doc.FullName + "</a>")); } } }

  • Cant get Tomcat6.0 to work with Windows 7 Environment

    - by CitadelCSCadet
    Prior to upgrading to windows 7, I was able to use Tomcat 6.0, but when I upgraded to the new Windows, and downloaded Eclipse EE, and downloaded the apache content, I am unable to get Apache to run. When I attempt to start my apacher server through either system tray, or even windows services, it gives the followign error screen. "Windows could not start the Apache Tomcat 6 on local computer. For more information review the system event log. Refer to server specific error code 0." I have been able to locate some forums about error code 0, and some other documentation on this problem, but none of the solutions seems to work. One of the solutions I came across said to take the msvcr71.dll (mscvrt.dll on new platforms) and put it into the bin folder of apache. This also did not work. Does anybody know a fix for this problem, or a way to get around it so I can get my server up and running thanks.

  • How to wait for thread to finish with .NET?

    - by Maxim Z.
    I've never really used threading before in C# where I need to have two threads, as well as the main UI thread. Basically, I have the following. public void StartTheActions() { //Starting thread 1.... Thread t1 = new Thread(new ThreadStart(action1)); t1.Start(); //Now, I want for the main thread (which is calling StartTheActions() ) to wait for t1 to finish (I have created an event in action1() for this) and then start t2... //HOW DO I DO THIS? Thread t2 = new Thread(new ThreadStart(action2)); t2.Start(); } So, essentially, my question is how to have a thread wait for another one to finish. What is the best way to do this? Thanks!

  • Why do my WPF UIElements NOT have OnPreview events?

    - by Matt.M
    I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

  • jQuery, Forms, Browser Refreshes

    - by Eric Cope
    I have a large form with some fields values dependent on previous elements. I use jquery's .trigger event to trigger the dependent field's update functions. When I refresh the page (click reload or click back), the previous values selected are still there, but the dependent fields are not reflecting the other element's values. How can I trigger the update functions upon refresh? I saw a way to prevent the browser from using the form's cached values. I'd rather use the cached values and update the elements dependent on the elements with cached values.

    I have an asp:calendar on my view page and as I hover over it..it shows a javascript postback status bar. but I have an asp:button also on the same page and when I hover over it. The action from the controller is in the status bar..because I have an onClick attribute for the button that triggers an action on the server side. and in the asp:calendar I also have a trigger event OnSelectionChanged the has a method on the server side...but as I said when I hover over the calendar to pick a date in the status bar it shows:javascript:_doPostBack($ct100ContentPlaceHolder?mycalendar',''3270) and when I click a date I receive an error that says object doesnt support this method..Also mycalendar is the id name of the asp:calendar

  • Learning rails and AJAX. How do I load a div via ajax and then toggle hiding/showing it?

    - by Kevin L.
    I'm doing my first Ruby on Rails project. I am working on a project where the user can add a new message. Then they can add updates to this message like a thread. I've got it all written and now I'm going back and applying some AJAX. I want to show just the main message when the page first loads. Then when I click a link I want an AJAX event to fire that populates a div with all the updates to the message. Then I want this same link to toggle hiding and showing the div. I've made a submit button to fire the ajax and get back the updates using form_remote_tag. I've also created a separate link to toggle the hiding using $(div_id).toggle();. But now I'm stuck on how to combine these two things into one all purpose link. Thanks.

  • How to override JS function from a firefox extension?

    - by BruceBerry
    Hello, I am trying to intercept calls to document.write for all pages. Setting up the interception inside the page by injecting a script like function overrideDocWrite() { alert("Override called"); document.write = function(w) { return function(s) { alert("special dom"); w.call(this, wrapString(s)); }; }(document.write); alert("Override finished"); } is easy and works, but i would like my extension to setup the interception for each document object from inside the extension. I couldn't find a way to do this. I tried to listen for the "load" event and set up the interception there but it also fails. How do I hook calls to doc.write from an extension?

  • Why does my ASP.NET user control's field value reset to 0?

Maybe perhaps the AccountGrid created with groupId 1 is not the one that is loaded to the page? public partial class AccountGrid : System.Web.UI.UserControl { int groupId = 0; public AccountGrid() { } // an aspx page creates AccountGrid with "new AccountGrid(1)" public AccountGrid(int groupId) { this.groupId = groupId; } protected void Page_Load(object sender, EventArgs e) { DataAccessFacade facade = new DataAccessFacade(); // groupId resets to 0 here... grdAccount.DataSource = facade.GetAccountsByAccountGroupId(this.groupId); grdAccount.DataBind(); } } In my page, I have public partial class Default : System.Web.UI.Page { public Default() { } public void Page_Load(object sender, EventArgs e) { ctlAccountGrid = new Views.Controls.Account.AccountGrid(1); // should I do databind? ctlAccountGrid.DataBind(); } }

  • To Make Diversity Work, Managers Must Stop Ignoring Difference

    - by HCM-Oracle
    By Kate Pavao - Originally posted on Profit Executive coaches Jane Hyun and Audrey S. Lee noticed something during their leadership development coaching and consulting: Frustrated employees and overwhelmed managers. “We heard from voices saying, ‘I wish my manager understood me better’ or ‘I hope my manager would take the time to learn more about me and my background,’” remembers Hyun. “At the same token, the managers we were coaching had a hard time even knowing how to start these conversations.”  Hyun and Lee wrote Flex to address some of the fears managers have when it comes to leading diverse teams—such as being afraid of offending their employees by stumbling into sensitive territory—and also to provide a sure-footed strategy for becoming a more effective leader. Here, Hyun talks about what it takes to create innovate and productive teams in an increasingly diverse world, including the key characteristics successful managers share. Q: What does it mean to “flex”? Hyun: Flexing is the art of switching between leadership styles to work more effectively with people who are different from you. It’s not fundamentally changing who you are, but it’s understanding when you need to adapt your style in a situation so that you can accommodate people and make them feel more comfortable. It’s understanding the gap that might exist between you and others who are different, and then flexing across that gap to get the result that you're looking for. It’s up to all of us, not just managers, but also employees, to learn how to flex. When you hire new people to the organization, they're expected to adapt. The new people in the organization may need some guidance around how to best flex. They can certainly take the initiative, but if you can give them some direction around the important rules, and connect them with insiders who can help them figure out the most critical elements of the job, that will accelerate how quickly they can contribute to your organization. Q: Why is it important right now for managers to understand flexing? Hyun: The workplace is becoming increasingly younger, multicultural and female. The numbers bear it out. Millennials are entering the workforce and becoming a larger percentage of it, which is a global phenomenon. Thirty-six percent of the workforce is multicultural, and close to half is female. It makes sense to better understand the people who are increasingly a part of your workforce, and how to best lead them and manage them as well. Q: What do companies miss out on when managers don’t flex? Hyun: There are high costs for losing people or failing to engage them. The estimated costs of replacing an employee is about 150 percent of that person’s salary. There are studies showing that employee disengagement costs the U.S. something like $450 billion a year. But voice is the biggest thing you miss out on if you don’t flex. Whenever you want innovation or increased productivity from your people, you need to figure out how to unleash these things. The way you get there is to make sure that everybody’s voice is at the table. Q: What are some of the common misassumptions that managers make about the people on their teams? Hyun: One is what I call the Golden Rule mentality: We assume when we go to the workplace that people are going to think like us and operate like us. But sometimes when you work with people from a different culture or a different generation, they may have a different mindset about doing something, or a different approach to solving a problem, or a different way to manage some situation. When see something that’s different, we don't understand it, so we don't trust it. We have this hidden bias for people who are like us. That gets in the way of really looking at how we can tap our team members best potential by understanding how their difference may help them be effective in our workplace. We’re trained, especially in the workplace, to make assumptions quickly, so that you can make the best business decision. But with people, it’s better to remain curious. If you want to build stronger cross-cultural, cross-generational, cross-gender relationships, before you make a judgment, share what you observe with that team member, and connect with him or her in ways that are mutually adaptive, so that you can work together more effectively. Q: What are the common characteristics you see in leaders who are successful at flexing? Hyun: One is what I call “adaptive ability”—leaders who are able to understand that someone on their team is different from them, and willing to adapt his or her style to do that. Another one is “unconditional positive regard,” which is basically acceptance of others, even in their vulnerable moments. This attitude of grace is critical and essential to a healthy environment in developing people. If you think about when people enter the workforce, they're only 21 years old. It’s quite a formative time for them. They may not have a lot of management experience, or experience managing complex or even global projects. Creating the best possible condition for their development requires turning their mistakes into teachable moments, and giving them an opportunity to really learn. Finally, these leaders are not rigid or constrained in a single mode or style. They have this insatiable curiosity about other people. They don’t judge when they see behavior that doesn’t make sense, or is different from their own. For example, maybe someone on their team is a less aggressive than they are. The leader needs to remain curious and thinks, “Wow, I wonder how I can engage in a dialogue with this person to get their potential out in the open.”

  • Two-key encryption/decryption?

    - by Matt
    I'm looking to store some fairly sensitive data using PHP and MySQL and will be using some form of reversible encryption to do so since I need to get the data back out in plain text for it to be of any use. I'll be deriving the encryption key from the users' username/password combination but I'm stumped for what to do in the (inevitable) event of a password being forgotten. I realise that the purpose of encryption is that it can only be undone using the correct key but this must have been addressed before.. I'm trying to get my head around whether or not public key cryptography would apply to the problem but all I can think of is that the private key will still need to be correct to decrypt the data.. Any ideas?

  • How do I find the previous/default value of a radio button in JS?

    - by royrules22
    I'm not sure if this is even possible, but I figured I'd ask before clubbing togehter an ugly solution. What I have is a group of radio buttons and I want to trigger a function if the radio button value is changed. For example say there are three buttons X Y and Z with Y default selected. If a user clicks on an unselected button (i.e. X or Z) then the function gets triggered but if he/she clicks on Y (which is already selected) nothing happens. Naturally the best solution would be to fire the function on an onchange event but IE6 doesn't fire onchange until the focus is no longer on the element which is not satisfactory. So is there a way to know what the previous value of the radio button was or at least what its default value is? I could easily create an array of default values and check against that but I'm trying to reduce the overhead. Please no jQuery suggestions ;)

  • FLEX: UIComponent Click Handler??

    - by davidemm
    Hello, Thanks for reading. I'm trying to put a label and an image on a UIComponent, side-by-side. I want to use UIComponent for efficiency reasons, and the entire component is more complicated than just a button with an icon. I'm trying to get a click handler on ther entire UIComponent so that when a click happens on either the label or the image, the same [click] event handler is called. If I add a click handler on the root component, it works, but when I introduce space between the label and the image, the space between them becomes un-clickable. I produce the space by using the move(x,y) method for the label and the image with a small gap between the x/y coordinates. Any ideas how to remedy this? Thanks.

  • Connecting data to a GUI - OOP

    - by tau
    I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

  • Handling exceptions, is this a good way?

    - by Jorge Córdoba
    We're struggling with a policy to correctly handle exceptions in our application. Here's our goals for it (summarized): Handle only specific exceptions. Handle only exceptions that you can correct Log only once. We've come out with a solution that involves a generic Application Specific Exception and works like this in a piece of code: try { // Do whatever } catch(ArgumentNullException ane) { // Handle, optinally log and continue } catch(AppSpecificException) { // Rethrow, don't log, don't do anything else throw; } catch(Exception e) { // Log, encapsulate (so that it won't be logged again) and throw Logger.Log("Really bad thing", e.Message, e); throw new AppSpecificException(e) } All exception is logged and then turned to an AppSpecificException so that it won't be logged again. Eventually it will reach the last resort event handler that will deal with it if it has to. I don't have so much experience with exception handling patterns... Is this a good way to solve our goals? Has it any major drawbacks or big red warnings?
