• API For Flex Apps To Interact

  - by dimo414

  I have a large flex application (the app) running on one server, and many small flex applications (widgets) running on another server, which are to be included in the app so that visually the user see's one continuous application. Due to proprietary third party software, this structure cannot be changed. I am looking for some way to allow the app and the widgets to communicate, allowing the app to make changes to the widgets and the the widgets to notify the app when events are triggered, so that user interaction is fluid and continuous. There are a few related questions which indicate it's possible to do this by setting up event triggers and listeners. I am wondering if there is any standardized way to do this (the answers aren't very clear) or if anyone has developed a library or API to make this easier.

• how to get memory dump after blue screen

  - by user464164

  I'm getting a lovely BSOD on bootup (STOP: 0x0000007E) from a driver I'm writing, and would like to load up the memory dump for analysis. However, it's not getting dumped anywhere. Everything is setup correctly in the Startup and Recovery settings, but I get no dump file, and nothing in the event log stating a dump has taken place. It looks like a dump is not even occurring... I know the exact line of code causing it (a call to IoAttachDevice()), but am not sure why, and would like to view the DbgPrint output to see where exactly it's failing. Could Windows possibly be crashing before the dumping functionality is set up? If so, how do I get access to the state of the machine when the failure occurs? UPDATE: Other possibly useful information: I'm running Windows XP through VirtualBox on a Linux host.

• ASP.Net - Gridview row selection and effects

  - by Clint

  I'm using the following code in attempt to allow the user to select a gridview row by clicking anywhere on the row (plus mouse over and out) effects. The code doesn't seem to be applied on rowdatabound and I can't break into the event. (It is wired). The control is in a usercontrol, that lives in a content page, which has a masterpage. protected void gvOrderTypes_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gvOrdTypes = (GridView)sender; //check the item being bound is actually a DataRow, if it is, //wire up the required html events and attach the relevant JavaScripts if (e.Row.RowType == DataControlRowType.DataRow) { e.Row.Attributes["onmouseover"] = "javascript:setMouseOverColor(this);"; e.Row.Attributes["onmouseout"] = "javascript:setMouseOutColor(this);"; e.Row.Attributes["onclick"] = Page.ClientScript.GetPostBackClientHyperlink(gvOrdTypes, "Select$" + e.Row.RowIndex); } }

• Trigger button click with JavaScript on Enter key in Text Box

  - by ziondreams

  I have one text input and one button (see below). How can I use JavaScript to trigger the button's click event when the Enter key is pressed inside the text box? There is already a different submit button on my current page, so I can't simply make the button a submit button. And, I only want the enter key to click this specific button if it is pressed from within this one text box, nothing else. <input type="text" id="txtSearch" /> <input type="button" id="btnSearch" value="Search" onclick="doSomething();" /> Update: I'd like to accept my own answer below, but since that is now allowed I will accept the next best solution.

• How to subscribe to EventHandler of a private control outside of Form

  - by randooom

  Hi all, maybe my design is not good, or I don't see the obvious solution, but I want to subscribe to a buttonClick EventHandler of Form1 from outside form1. For example I have a Controller and Form1 who are both instanced in the main function. Now I want to subscribe a function from Controller to the buttonClick event from Button1_Click in Form1. But the button1 is declarded private, so i can't do form1->Button1->Click += gcnew EventHandler(controller->function) Is there any way to get around this? Ok I could write a setter or something in Form1, but is there any other solution? I read some examples, but they are all calling events from within the same class so they don't address my specific problem.

• How to calculate the touch location with convertToWorldSpace?

  - by Paul

  i would like to convert the touch location as a world coordinate in my tile game. With this code, i clicked on the right of the screen (so that my character walks in the tiled game, and the background goes slowly to the left) : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL: location]; CGPoint test = [self convertToWorldSpace:location]; CCLOG(@"test : %.2g", test.x); The test log gives me : 50, 72, 1e+02, 2.6e+02, 4.2e+02, (and then goes down) 3.2e+02, 9.5, -1.9e+02, etc. Does anyone know why? I would like to calculate the "real" coordinate of the touch, so that i know when the character has to keep going (click on the right of its actual position) or if he has to turn and go backwards. (click on the left of its actual position) Thanks for your help

• JQuery - which form was submitted?

  - by OneMostFrustratedChap

  Hello, I have a page of products and for each of them, I want to have a form that uses AJAX to update the session. I've done this bit - just providing background. I use the product's ID to create a different form class and name for each form, so each form is called something like this_form_name_567 and the next would be this_form_name_568 and so on. There is a submit button per form. I'm having trouble figuring out a) which event is best to use so that the correct form will be identified when a submit button is clicked, b) once clicked, how to then make sure the correct value is taken from a hidden field (unique ID) within the submitted form so that I can populate a line of code such as: $.post("compare_response.php", {compare_this: $("#compare_this").val()}, function(data){ } Any help would be greatly appreciated. Thank you

In this function if I say mycomponent._urlRequest ="http://mysite.com" the httpservice throws a null url error but if I say mycomponent.srv.url="http://mysite.com" it works fine. Why is this?

• 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.”

• Iframe auto-height not working when page changes in IE

  - by DisgruntledGoat

  I have an iframe in a page, with the following auto-height script. function autoHeight(e) { if ( e.contentDocument ) { e.height = e.contentDocument.body.offsetHeight + 35; } else { e.height = e.contentWindow.document.body.scrollHeight + 35; } } document.domain = "totalstudents.co.uk"; var ifr = document.getElementById('housingdata'); ifr.onload = function() { autoHeight(ifr); } The iframe resizes fine when the outer page is loaded, but when I go to a new page in the iframe, scrollbars appear and the page does not get resized in Internet Explorer. In other browsers the iframe gets resized, because the onload event fires each time. I'm using IE8 but the outer page is setting it to IE7 compatibility mode. Is there a workaround for IE?

• assistance with fxcop

  - by amateur

  I am at present developing a mvc4 project that comunicates to a set of wcf services. I am setting such up in tfs build for a team of developers. I am very much a newbie to fxcop and code analysis in general. I am currently researching it and have some questions following this: Is it recommended to use the rules that come with fxcop? Should it be included as a build task during builds? What is the value from it? Are there guidelines to what rules to abide by or is it best to go with the default? Is it correct to run the analysis as a post build event? I am a newbie to fxcop and would like some feedback. I am as it is integrating stylecop in to my build.

• ASP.NET: Including JavaScript libraries conditionally from CDN

  - by DigiMortal

  When developing cloud applications it is still useful to build them so they can run also on local machine without network connection. One thing you use from CDN when in cloud and from app folder when not connected are common JavaScript libraries. In this posting I will show you how to add support for local and CDN script stores to your ASP.NET MVC web application. Our solution is simple. We will add new configuration setting to our web.config file (including cloud transform file of it) and new property to our web application. In master page where scripts are included we will include scripts from CDN conditionally. There is nothing complex, all changes we make are simple ones. 1. Adding new property to web application Although I am using ASP.NET MVC web application these modifications work also very well with ASP.NET Forms. Open Global.asax and add new static property to your application class. public static bool UseCdn {     get     {         var valueString = ConfigurationManager.AppSettings["useCdn"];         bool useCdn;           bool.TryParse(valueString, out useCdn);         return useCdn;     } } If you want less round-trips to configuration data you can keep some nullable boolean in your application class scope and load CDN setting first time it is asked. 2. Adding new configuration setting to web.config By default my application uses local scripts. Although my application runs on cloud I can do a lot of stuff without staging environment in cloud. So by default I don’t have costs on traffic when including scripts from application folders. <appSettings>   <add key="UseCdn" value="false" /> </appSettings> You can also set UseCdn value to true and change it to false when you are not connected to network. 3. Modifying web.config cloud transform I have special configuration for my solution that I use when deploying my web application to cloud. This configuration is called Cloud and transform for this configuration is located in web.cloud.config. To make application using CDN when deployed to cloud we need the following transform. <appSettings>   <add key="UseCdn"        value="true"        xdt:Transform="SetAttributes"        xdt:Locator="Match(key)" /> </appSettings> Now when you publish your application to cloud it uses CDN by default. 4. Including scripts in master pages The last thing we need to change is our master page. My solution is simple. I check if I have to include scripts from CDN and if it is true then I include scripts from there. Otherwise my scripts will be included from application folder. @if (MyWeb.MvcApplication.UseCdn) {     <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.4.min.js" type="text/javascript"></script> } else {     <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> } Although here is only one script shown you can add all your scripts that are also available in some CDN in this if-else block. You are free to include scripts from different CDN services if you need. Conclusion As we saw it was very easy to modify our application to make it use CDN for JavaScript libraries in cloud and local scripts when run on local machine. We made only small changes to our application code, configuration and master pages to get different script sources supported. Our application is now more independent from external sources when we are working on it.

• Put a program in the system tray at startup

  - by cosmo0

  Hi I followed the commonly-linked tip for reducing an application to the system tray : http://www.developer.com/net/csharp/article.php/3336751 Now it works, but there is still a problem : my application is shown when it starts ; I want it to start directly in the systray. I tried to minimize and hide it in the Load event, but it does nothing. Edit : I could, as a poster suggested, modify the shortcut properties, but I'd rather use code : I don't have complete control over every computer the soft is installed on. I don't want to remove it completely from everywhere except the systray, I just want it to start minimized. Any ideas ? Thanks

• parsing primitive types using java.util.Scanner
