  • What information do you capture your software crashes in the field?

    - by Russ
    I am working on rewriting my unexpected error handling process, and I would like to ask the community: What information do you capture both automatic, and manually, when software you have written crashes? Right now, I capture a few items, some of which are: Automatic: Name of app that crashed Version of app that crashed Stack trace Operating System version RAM used by the application Number of processors Screen shot: (Only on non-public applications) User name and contact information (from Active Directory) Manual: What context is the user in (i.e.: what company, tech support call number, RA number, etc...) When did the user expect to happen? (Typical response: "Not to crash”) Steps to reproduce. What other bits of information do you capture that helps you discover the true cause of an applications problem, especially given that most users simply mash the keyboard when asked to tell you what happened. For the record I’m using C#, WPF and .NET version 4, but I don’t necessarily want to limit myself to those.

  • Flex Problem Enabling and Disabling Button in List

    - by pfunc
    I have a list with a dataprovider, it lists out buttons encapsulated in an item renderer. All I want it to do is have a skin that it changes to when it is clicked. I can get this to happen, but then it just goes back to its up state. I want it to stick on the down state, which I have to do by disabling the button. So I tried this: buttonList.selectedItem.enabled = false; for(var i:Number = 0; i< buttonList.numChildren; i++) { var loopBtn = buttonList.getChildAt(i); if(loopBtn != buttonList.selectedItem) { loopBtn.enabled = true; } } But this doesn't seem to work. What am I doing wrong here?

  • help me understand JS execution on onclick event of button

    - by Anil Namde
    <input type="button" name="reset" onclick="return ValidateValue(); __doPostBack('ApplyBtn','')" /> The above is the code generated for asp server button button control on browser. Now my query is that irrespective of ValidateValue() returning true/false __doPostBack('ApplyBtn','') function is not showing any effect for me. My understanding is that string passed to onclick acts like function body, and return will from first function will return control preventing second function from execution. Is that correct ? Please provide helpful inputs.

  • Overwrite queryset which builds filter sidebar

    - by cw
    Hi, I'm writing a hockey database/manager. So I have the following models: class Team(models.Model): name = models.CharField(max_length=60) class Game(models.Model): home_team = models.ForeignKey(Team,related_name='home_team') away_team = models.ForeignKey(Team,related_name='away_team') class SeasonStats(models.Model): team = models.ForeignKey(Team) Ok, so my problem is the following. There are a lot of teams, but Stats are just managed for my Club. So if I use "list_display" in the admin backend, I'd like to modify/overwrite the queryset which builds the sidebar for filtering, to just display our home teams as a filter option. Is this somehow possible in Django? I already made a custom form like this class SeasonPlayerStatsAdminForm(forms.ModelForm): team = forms.ModelChoiceField(Team.objects.filter(club__home=True)) So now just the filtering is missing. Any ideas?

  • Windows Identity Foundation - Local STS on Windows Azure.

    - by joe
    Hello, I am trying to use Federated authentication on Azure. I found a example of having a local sts outside azure which is used for authentication from a web role hosted in azure. This works perfectly. My issue is, i dont want to have an application outside azure. Instead, I want to host the local sts website also in azure. So in effect I will have two web roles (1. my actual website, 2. the sts). I tried the above approach my creating a new webrole and moving the files from my original sts project. But i am getting compilation errors even if I reference the required dlls. I have also set "copy local" to true. It will be very helpful if somebody can guide me.. Thanks

  • Is there a reliable way to activate / set focus to a window using C#?

    - by gtaborga
    Hey everyone, I'm trying to find a reliable way to activate / set focus a window using C#. Currently I'm attempting to achieve this using the following Windows API calls: SetActiveWindow(handle); SwitchToThisWindow(handle, true); Previously I also had ShowWindow(handle, SW_SHOWMAXIMIZED); executing before the other 2, but removed it because it was causing strange behavior. The problem I'm having with my current implementation is that occasionally the focus will not be set correctly. The window will become visible but the top part of it will still appear grayed out as if it wasn't in focus. Is there a way to reliably do this which works 100% of the time, or is the inconsistent behavior a side-effect I can't escape? Please let me know if you have any suggestions or implementations that always work. Thank you for your time.

  • Html encoding in MVC input

    - by fearofawhackplanet
    I'm working through NerdDinner and I'm a bit confused about the following section... First they've added a form for creating a new dinner, with a bunch of textboxes delcared like: <%= Html.TextArea("Description") %> They then show two ways of binding form input to the model: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create() { Dinner dinner = new Dinner(); UpdateModel(dinner); ... } or: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(Dinner dinner) { ... } Ok, great, that all looks really easy so far. Then a bit later on they say: It is important to always be paranoid about security when accepting any user input, and this is also true when binding objects to form input. You should be careful to always HTML encode any user-entered values to avoid HTML and JavaScript injection attacks Huh? MVC is managing the data binding for us. Where/how are you supposed to do the HTML encoding?

  • jquery multiple select x rails edit action

    - by VP
    Hi, i'm using the JQUERY multiselectable plugin. Because it's get one select box and transform it in two, where you can move one selected option to another select box. The problem is that i'm facing some problems with the edit action. When i load the form, the selected values (that are saved in my model) are not being populated in the "selected" select box. There is anybody with a good idea about how to "automatically" move the selected values in my database from the "available to be selected" to "selected" options? For now i'm doing something like <%= select "product", :option_ids, options_for_select(Option.all.map { |opt| [opt.description, opt.id]}), {},{:multiple=> true,:class=>'multiselect'} %> Here i can see already the problem. I could just use as options_for_select just all options - the options that are already choosed in my model. The problem is how to update the select box with this information?

  • Can't get ellipsis to work on Android

    - by Mark
    Hi, I have a TextView. I want it to ellipsize if longer than its available width. This does not work unless the input string has no spaces... can anyone provide an example of this working? I've tried different combinations of: singleLine="true" maxLines="1" scrollHorizontally="false" none of these have any effect. Again, if I supply a string that has no spaces in it, then the ellipsis appears correctly. What am I missing? I've tried this on 1.5, 1.6, 2.0, all same problem. Thanks

  • Why wouldn't I be able to establish a trust relationship for a SSL/TLS channel?

    - by Abe Miessler
    I have a piece of .NET code that is erroring out when it makes a call to HTTPWebRequest.GetRequestStream. Here is the error message: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. I've read a few things that suggest that I might need a certificate on the machine running the code, but i'm not sure if that's true or how to do it. If I need to get a certificate, how do I do it? Code: var request = (HttpWebRequest)HttpWebRequest.Create(requestUrl); //my url request.Method = StringUtilities.ConvertToString(httpMethod); // Set the http method GET, POST, etc. if (postData != null) { request.ContentLength = postData.Length; request.ContentType = contentType; using (var dataStream = request.GetRequestStream()) { dataStream.Write(postData, 0, postData.Length); } }

  • Writing Java code in Matlab?

    - by scooziexp
    Hi, I'm trying to use the Java commands pw.println() and br.readLine() in Matlab because I have set up a socket (input_socket2) between Matlab and a command-line program I want to control using Java classes BufferedReader and PrintWriter. Before the following snippet of code, I implemented another socket that goes between 2 computers. This works great and I also know that the following snippet of code successfully opens up a communication line between Matlab and the other program. However, Matlab throws an error at pw.println('noop'). I think it has something to do with syntax, but I'm not sure how to write the command in Matlab syntax then: try input_socket2 = Socket(host2,port2); input_stream2 = input_socket2.getInputStream; d_input_stream2 = DataInputStream(input_stream2); br = BufferedReader(InputStreamReader(input_stream2)); pw = PrintWriter(input_socket2.getOutputStream,true); pw.println('noop') br.read end Any ideas?

  • OpenLayers FramedCloud Autosizing

    - by Kyle
    According to the documentation, I should be able to configure the size of my OpenLayers popup by declaring an OpenLayers.Size object in the FramedCloud constructor: this.popup = new OpenLayers.Popup.FramedCloud('featurePopup', this.options.feature.geometry.getBounds().getCenterLonLat(), new OpenLayers.Size(80, 60), this.template(this.formattedAttrs()), null, true, this.onPopupClose ); Currently the popup that is rendered is autosized no matter what dimensions I use in the constructor. I've tried manually setting the autosizing attribute of the FramedCloud to false as well as manually adjusting the css styling for the popup without achieving the results I need. I checked and found some similar issues in the OpenLayers 2.11 issues list, but I haven't found a workaround. Any ideas?

  • JNI: dll function works ok in C++ main, but not with dll wrapper

    - by Joseph Lim
    I have an a.dll (not modifiable as i do not have the source) with a function bool openPort(DWORD mem).I wrote a c++ main, loaded this dll using LoadLibrary, and the function works well.It returns true. Now, I need to call this function from Java via JNI. I wrote another b.dll with a function like so JNIEXPORT void JNICALL Java_MyClass_openPortFunc (JNIEnv *env, jobject obj, jint pMemPhy) { hInstLibrary = LoadLibrary("a.dll"); typedef bool (*openPort)(DWORD); openPort _openPort; _openPort = (openPort)GetProcAddress(hInstLibrary, "openPort"); DWORD memAddr = 0xda000; if(_openPort(memAddr)){ cout << "ok" << endl; }else{ cout << "failed " << endl; } } This however, causes the openPort to return false despite using the same parameters. I hope someone can advise me. Thank you. :)

  • RelativeLayout - positioning a View under a ViewGroup

    - by Richard
    I have the following structure defined in an xml layout file. <RelativeLayout android:id="@+id/mainLayout" xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <FrameLayout android:id="@+id/frame" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" ></FrameLayout> <Button android:id="@+id/button" android:layout_below="@id/frame" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </RelativeLayout> The FrameLayout is positioned correctly in the center of its parent. But the Button isn't getting positioned under it. Instead it's displaying in the top left corner. Am I doing something incorrectly or is this a bug with RelativeLayout?

  • Rsspnse.redirect will not redirect on Internet explorer

    - by Amit
    Hi, I am using Response.Redirect("someurl",true); in the page_preInit event to redirect all the requests that come to a page. It works fine on Firexox, but if i access the page from internet explorer 7/8, it says page can not be found and will not redirect to new URL. Any idea why this happens?? Update: I tried giving a radom URL in the redirect such as google.com and it works fine. Actually the URL I am trying to redirect is not accessible on my machine, it is on another VPN. I guess IE will not change the URL on the addressbar if it can not access the URL. Firefox on the other hand changes the address on the address bar.

  • Time complexity O() of isPalindrome()

    - by Aran
    I have this method, isPalindrome(), and I am trying to find the time complexity of it, and also rewrite the code more efficiently. boolean isPalindrome(String s) { boolean bP = true; for(int i=0; i<s.length(); i++) { if(s.charAt(i) != s.charAt(s.length()-i-1)) { bP = false; } } return bP; } Now I know this code checks the string's characters to see whether it is the same as the one before it and if it is then it doesn't change bP. And I think I know that the operations are s.length(), s.charAt(i) and s.charAt(s.length()-i-!)). Making the time-complexity O(N + 3), I think? This correct, if not what is it and how is that figured out. Also to make this more efficient, would it be good to store the character in temporary strings?

  • Refining Solr searches, getting exact matches?

    - by thebluefox
    Afternoon chaps, Right, I'm constructing a fairly complex (to me anyway) search system for a website using Solr, although this question is quite simple I think... I have two search criteria, location and type. I want to return results that are exact matches to type (letter to letter, no exceptions), and like location. My current search query is as follows ../select/?q=location:N1 type:blue&rows=100&fl=*,score&debugQuery=true This firstly returns all the type blue's that match N1, but then returns any type that matches N1, which is opposite to what I'm after. Both fields are set as textgen in the Solr schema. Any pointers? Cheers gang
