  • Problem setting row backgrounds in Android Listview

    - by zchtodd
    I have an application in which I'd like one row at a time to have a certain color. This seems to work about 95% of the time, but sometimes instead of having just one row with this color, it will allow multiple rows to have the color. Specifically, a row is set to have the "special" color when it is tapped. In rare instances, the last row tapped will retain the color despite a call to setBackgroundColor attempting to make it otherwise. private OnItemClickListener mDirectoryListener = new OnItemClickListener(){ public void onItemClick(AdapterView parent, View view, int pos, long id){ if (stdir.getStationCount() == pos) { stdir.moreStations(); return; } if (playingView != null) playingView.setBackgroundColor(Color.DKGRAY); view.setBackgroundColor(Color.MAGENTA); playingView = view; playStation(pos); } }; I have confirmed with print statements that the code setting the row to gray is always called. Can anyone imagine a reason why this code might intermittently fail? If there is a pattern or condition that causes it, I can't tell. I thought it might have something to do with the activity lifecycle setting the "playingView" variable back to null, but I can't reliably reproduce the problem by switching activities or locking the phone. private class DirectoryAdapter extends ArrayAdapter { private ArrayList<Station> items; public DirectoryAdapter(Context c, int resLayoutId, ArrayList<Station> stations){ super(c, resLayoutId, stations); this.items = stations; } public int getCount(){ return items.size() + 1; } public View getView(int position, View convertView, ViewGroup parent){ View v = convertView; LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (position == this.items.size()) { v = vi.inflate(R.layout.morerow, null); return v; } Station station = this.items.get(position); v = vi.inflate(R.layout.songrow, null); if (station.playing) v.setBackgroundColor(Color.MAGENTA); else if (station.visited) v.setBackgroundColor(Color.DKGRAY); else v.setBackgroundColor(Color.BLACK); TextView title = (TextView)v.findViewById(R.id.title); title.setText(station.name); return v; } };

  • Using s/// in an expression

    - by mikeY
    I got a headache looking for this: How do you use s/// in an expression as opposed to an assignment. To clarify what I mean, I'm looking for a perl equivalent of python's re.sub(...) when used in the following context: newstring = re.sub('ab', 'cd', oldstring) The only way I know how to do this in perl so far is: $oldstring =~ s/ab/cd/; $newstring = $oldstring; Note the extra assignment.

  • Some languages don't work when using Word 2007 Spellcheck from Interop

    - by Tridus
    I'm using the Word 2007 spellchecker via Interop in a VB.net desktop app. When using the default language (English), it works fine. If I set the language to French via LanguageId, it also works. But if I set it to French (Canadian) (Word.WdLanguageID.wdFrenchCanadian), it doesn't work. There's no error message, it simply runs and says the document contains no errors. I know it does, if I paste the exact same text into Word itself and run it with the French (Canadian) dictionary, it finds errors. Just why that dictionary doesn't work is kind of a mystery to me. Full code below: Public Shared Function SpellCheck(ByVal text As String, ByVal checkGrammar As Boolean) As String ' If there is no data to spell check, then exit sub here. If text.Length = 0 Then Return text End If Dim objWord As Word.Application Dim objTempDoc As Word.Document ' Declare an IDataObject to hold the data returned from the ' clipboard. Dim iData As IDataObject objWord = New Word.Application() objTempDoc = objWord.Documents.Add objWord.Visible = False ' Position Word off the screen...this keeps Word invisible ' throughout. objWord.WindowState = 0 objWord.Top = -3000 ' Copy the contents of the textbox to the clipboard Clipboard.SetDataObject(text) ' With the temporary document, perform either a spell check or a ' complete ' grammar check, based on user selection. With objTempDoc .Content.Paste() .Activate() .Content.LanguageID = Word.WdLanguageID.wdFrenchCanadian If checkGrammar Then .CheckGrammar() Else .CheckSpelling() End If ' After user has made changes, use the clipboard to ' transfer the contents back to the text box .Content.Copy() iData = Clipboard.GetDataObject If iData.GetDataPresent(DataFormats.Text) Then text = CType(iData.GetData(DataFormats.Text), _ String) End If .Saved = True .Close() End With objWord.Quit() Return text End Function

  • Invoking web service methods from code-behind

    - by Peter Wone
    The application on which I am working has a web service exposing various methods. Most of these methods use WebOperationContext.Current to set headers up to prevent cacheing. This works fine when the service methods are consumed in AJAX via the generated proxy, but when I attempt to do the same thing from code-behind, WebOperationContext.Current is null. Can anyone tell me how to confer appropriate call context on the method invocation?

  • Gaining access to jndi environment variables within a Tomcat LifecycleListener

    - by rmarimon
    I'm using a LifecycleListener in tomcat to initialize some objects required by contexts in my web server. Within LifecycleListener I would like to have access to GlobalNamingResources Environment variables to keep the configuration for the server inside the server.xml file. When trying various approaches I get the following error: javax.naming.NameNotFoundException: Name java:comp is not bound in this Context I'm assuming that the jndi is not initialized by this stage of the server startup process. Any ideas on how to tackle this?

  • Is a full html page needed when loading a page with jQuery mobile?

    - by Vincent Hiribarren
    I am currently looking at jQuery mobile and its system of loading web pages with XmlHttpRequest. Thanks to that it is possible to automatically perform transition animations between two pages, for instance. However, something is not clear to me. If I understand correctly, each new page of a jQuery mobile powered website is injected in the DOM of the initial web page. The documentation of jQuery mobile even tells that because of this mechanism, the <title> tag of new webpages are not taken into account. So, in a way, if my initial webpage A.html loads a page B.html, I would tend to think that the webpage B.html does not need to have a full HTML grammar with the <html>, <head> or <body> tags. My page B.html could directly begin with a <div> element. Am I right?Is a full html page needed when loading a HTML page with jQuery mobile?What are the pros and cons about having a webpage with a wrong/truncated HTML syntax (appart that this page should not be accessed directly but through the main page)?

  • How can I make properties in properties files mandatory in Spring?

    - by Paulo Guedes
    I have an ApplicationContext.xml file with the following node: <context:property-placeholder location="classpath:hibernate.properties, classpath:pathConfiguration.properties" /> It specifies that both properties files will be used by my application. Inside pathConfiguration.properties, some paths are defined, such as: PATH_ERROR=/xxx/yyy/error PATH_SUCCESS=/xxx/yyy/success A PathConfiguration bean has setters for each path. The problem is: when some of those mandatory paths are not defined, no error is thrown. How and where should I handle this problem?

  • How to extract ALL typedefs and structs and unions from c++ source

    - by Michael Wells
    I have inherited a Visual Studio project that contains hundreds of files. I would like to extract all the typedefs, structs and unions from each .h/.cpp file and put the results in a file). Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. typdef int myType; struct myFirstStruct { char a; int b;...}; union Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}myUnion; struct { bool c; int d;...}mySecondStruct; My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this). Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) Or a tool to accomplish this. Edit: I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.

  • Which project management software for technophobes who've never worked with something like that?

    - by Ernst
    Hi, Our director has asked me to get something to manage projects. Note that so far we haven't used anything of the sort. I did not get very clear instructions yet, probably because she doesn't know exactly what we need either. My guess is, we'll only find out while using something. I've looked at some, openworkbench, ganttproject, and microsoft project. The latter has the advantage of easy importing of users from exchange, are there others that do that (even if not directly, easily)? I don't think it's a critical requirement though. We're using some other custom software where I have to add users manually anyway and we're small enough that it's maybe once a month that I have to add or remove a user. In any case, I'm not in favour of buying anything, since I'm skeptic about us actually succeeding in putting it to good use, and even if we do, we will only during usage discover what we need. We're also not a tech shop, most people vary from not very technically adept to technophobic. This means we need something very userfriendly. I prefer to stay away from online solutions, since we deal with sensitive information and I prefer to keep that in house, but I guess it would be acceptable for the trial period. An intranet site is an option though, but preferably something that is easy to set up with IIS. Xplanner plus and redmine I found too hard to set up for this experiment. Some other options I haven't yet tried to install, but which look to complex for our technophobes: Endeavour Software Project Management, Project-Open, Trac. Any suggestions? Thanks, Ernst

  • What good open source programs exist for fuzzing popular image file types?

    - by JohnnySoftware
    I am looking for a free, open source, portable fuzzing tool for popular image file types that is written in either Java, Python, or Jython. Ideally, it would accept specifications for the fuzzable fields using some kind of declarative constraints. Non-procedural grammar for specifying constraints are greatly preferred. Otherwise, might as well write them all in Python or whatever. Just specifying ranges of valid values or expressions for them. Ideally, it would support some kind of generative programming to export the fuzzer into various programming languages to suit cases where more customization was required. If it supported a direct-manipulation GUI for controlling parameter values and ranges, that would be nice too. The file formats that should be supported are: GIF JPEG PNG So basically, it should be sort of a toolkit consisting of ready-to-run utility, a framework or library, and be capable of generating the fuzzed files directly as well as from programs it generates. It needs to be simple so that test images can be created quickly. It should have a batch capability for creating a series of images. Creating just one at a time would be too painful. I do not want a hacking tool, just a QA tool. Basically, I just want to address concerns that it is taking too long to get commonplace image rendering/parsing libraries stable and trustworthy.

  • Why would Visual Studio 2010 say it can't show a variable during debug?

    - by Edward Tanguay
    In Visual Studio 2010 sometimes when I want to get the value of a variable while debugging, it tells me that it "does not exist in this context" when it obviously does. I have found that if I use the variable, as in the screenshot below, then it is able to show it. Has anyone experienced this? Visual Studio 2008 never did this. How can I get Visual Studio 2010 to always show me variable values while debugging?

  • Different ways of accessing configuration parameters from a JAX-WS service

    - by ecerulm
    As far as I know I can access the web.xml <context-param>s by making my class implement ServletContextListener and use the ServletContext.getInitParam(String) to read them, but it´s cumbersome as only one instance of the class will receive the contextInitialized(ServletContextEvent sce) call, so I need to make the ServletContext an static member of the class. What other ways exist of setting conf params at deployment time and what are the recommended ones?

  • Executing JavaScript with Python without X.

    - by Thomas
    I want to parse a html-page that unfortunately requires JavaScript to show any content. In order to do so I use a small python-script that pulls the html-code of the page, but after that I have to execute the JavaScript in a DOM-context which seems pretty hard. To make it even harder I want to use it in a server environment that has no X11-server. Note: I already read about http://code.google.com/p/pywebkitgtk/ but it seems to need a X-server.

  • QWebFrame::evaluateJavaScript vs. script-tag in HTML

    - by jwg
    Hi, I want to develop an application that uses QtWebKit and JQuery. What I need to know is, is there any difference between reading JQuery from a file and evaluateJavaScript it, or embedding it as a script tag within the "page" that is displayed within the widget? If there is a difference, I am curious if anyone could explain why it would be. As far as I understood it, evaluateJavaScript() would feed the script parameter to the JavaScript interpreter, which interprets it in the current page's context. Thanks.

  • Is it bad to redirect http to https?

    - by jasondavis
    I just installed an SSL Certificate on my server. I use a web hosting panel called ZPanel that is an open source project. It then set up a redirect for all traffic on my domain on Port 80 to redirect it to Port 443. In other words, all my http://example.com traffic is now redirected to the appropriate https://example.com version of the page. The redirect is done in my Apache Virtual Hosts file with something like this... RewriteEngine on ReWriteCond %{SERVER_PORT} !^443$ RewriteRule ^/(.*) https://%{HTTP_HOST}/$1 [NC,R,L] My question is, are there any drawbacks to using SSL? Since this is not a 301 Redirect, will I lose link juice/ranking in search engines by switching to https? I appreciate the help. I have always wanted to set up SSL on a server, just for the practice of doing it, and I finally decided to do it tonight. It seems to be working well so far, but I am not sure if it's a good idea to use this on every page. My site is not eCommerce and doesn't handle sensitive data; it's mainly for looks and the thrill of installing it for learning. UPDATED ISSUE Strangely Bing creates this screenshot from my site now that it is using HTTPS everywhere...
