20,117,802 | 0 | Open links in webview android html <p>I am developing a webbased app for android, winpho and ios. One of the sections has a link to download a pdf.</p> <p>In winpho and ios, keep pressing for a second open a menu to open, download or save document but in android, seems to do nothing. I can't open just pressing once the button or open in another window or nothing.</p> <p>I don't know if I have to declare the button in other way in html or it just doesn't work in android. </p> <p>Any idea about what is the problem? If you need my html code, just ask but it is just a normal link with href=url.</p> <p>I added the android part in which I open the webpage: </p> <pre><code>mywebview = (WebView) findViewById(R.id.webview); if (savedInstanceState == null){ mywebview.loadUrl(url); } </code></pre> <p>The url is a normal webapage with a button on in. Clicking that button, the pdf is opened. In android chrome, it works. </p> |

8,778,008 | 0 | <p>The trouble here is that the underlying .NET dataset designer isn't properly schema-aware.

What I'd like for it to do is accept a command-line flag in place of req *http.Request.</p> </blockquote> <p>If you read <a href="http://golang.org/doc/go_spec.html" rel="nofollow noreferrer">The Go Programming Language Specification</a>, <a href="http://golang.org/doc/go_spec.html#Types" rel="nofollow noreferrer">§Types</a>, including <a href="http://golang.org/doc/go_spec.html#Function_types" rel="nofollow noreferrer">§Function types</a>, you will see that Go has strong static typing, including function types. While this does not guarantee to catch all errors, it usually catches attempts to use invalid, non-matching function signatures.</p> <p>You don't tell us why you want to change the function signature for <code>QR</code>, in what appears to be an arbitrary and capricious fashion, so that it is no longer a valid <code>HandlerFunc</code> type, guaranteeing that the program will fail to even compile. We can only guess what you want to accomplish. Perhaps it's as simple as this: you want to modify the <code>http.Request</code>, based on a runtime parameter. Perhaps, something like this:</p> <pre><code>// Note: flag.Parse() in func main() {...} var qrFlag = flag.String("qr", "", "function QR parameter") func QR(c *http.Conn, req *http.Request) { if len(*qrFlag) > 0 { // insert code here to use the qr parameter (qrFlag) // to modify the http.Request (req) } templ.Execute(req.FormValue("s"), c) } </code></pre> <p>Perhaps not!

490,919 | 0 | <p>Locking is platform and device specific, but generally, you have a few options:</p> <ol> <li>use flock(), or equivilent (if your os supports it). This is advisory locking, unless you check for the lock, its ignored.</li> <li>Use a lock-copy-move-unlock methodology, where you copy the file, write the new data, then move it (move, not copy - move is an atomic operation in Linux -- check your OS), and you check for the existence of the lock file.</li> <li>Use a directory as a "lock". This is necessary if you're writing to NFS, since NFS doesn't support flock().</li> <li>There's also the possibility of using shared memory between the processes, but I've never tried that; its very os-specific.</li> </ol> <p>For all these methods, you'll have to use a spin-lock (retry-after-failure) technique for acquiring and testing the lock. This does leave a small window for mis-synchronization, but its generally small enough to not be an major issue.</p> <p>If you're looking for a solution that is cross platform, then you're better off logging to another system via some other mechanism (the next best thing is the NFS technique above). </p> <p>Note that sqlite is subject to the same constraints over NFS that normal files are, so you can't write to an sqlite database on a network share and get synchronization for free.</p> |

Because NHibernate is popular and very good at what it does, and EF is likely to pick up most of the remainder (particularly devs that don't want to stray from Microsoft-supplied frameworks), the barrier to entry for a new player is very high. Another ORM would need to add something significant over and above what NHibernate currently offers in order to get any reasonable level of interest. </p> <p>If there was an open source project that wanted to deliver better Linq support in an ORM, in my opinion it would have greater success contributing to NHibernate Linq rather than attempting to build its own framework from scratch.</p> |

While it's thread-safe it doesn't mean you will get what expected when using it from different threads. For example, suppose you have the following code:</p> <pre><code>StringBuffer buf = new StringBuffer(); public void appendMessage(String message) { buf.append("INFO: ").append(message).append(System.lineSeparator()); } </code></pre> <p>If you are using it in multithread environment it will not fail, but you may end up having content like this:</p> <pre><code>INFO: INFO: thread1 message thread2 message </code></pre> <p>That's because individual <code>append</code> calls are synchronized, but the whole sequence is not.</p> <p>In order to ensure that your messages are separately added, you must have an external synchronization like this:</p> <pre><code>Object lock = new Object(); StringBuilder buf = new StringBuilder(); public void appendMessage(String message) { synchronized(lock) { buf.append("INFO: ").append(message).append(System.lineSeparator()); } } </code></pre> <p>Here the whole sequence of calls is synchronized, so you will have the whole message appended at once. And as you are using the external synchronization, <code>StringBuilder</code> will work fine as well.</p> <p>So in general <code>StringBuffer</code> should not be used in the most of situations.</p> |

31,715,355 | 0 | <p>From the <a href="https://docs.python.org/2/library/webbrowser.html#webbrowser.open" rel="nofollow">doc</a>.</p> <blockquote> <p>The webbrowser module provides a high-level interface to allow displaying Web-based documents to users. Under most circumstances, simply calling the open() function from this module will do the right thing.</p> </blockquote> <p>You have to import the module and use <code>open()</code> function.</p> <p><strong>To open in new tab:</strong></p> <pre><code>import webbrowser webbrowser.open('nabinkhadka.com.np', new = 2) </code></pre> <p><strong>Also from the doc.</strong></p> <blockquote> <p>If new is 0, the url is opened in the same browser window if possible. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page (“tab”) is opened if possible</p> </blockquote> <p>So according to the value of new, you can either open page in same browser window or in new tab etc.</p> <p>Also you can specify as which browser (chrome, firebox, etc.) to open. Use <strong>get()</strong> function for this.</p> |
28,196,027 | 0 | <p>The problem you're having is not related to GWT <em>per se</em>, but with Java itself. When you do:</p> <pre><code>private void setMuplDef(MultiUploader muplDef, ...) { muplDef = new MultiUploader(); </code></pre> <p>... you must remember that in Java you always copy the reference of the parameter when you call a method (more about that in <a href="http://stackoverflow.com/questions/40480/is-java-pass-by-reference-or-pass-by-value">here</a>). In that matter, you can't pass your <code>muplDefPdf</code> field as parameter expecting it to be instantiated inside the method.</p> <p>For your code to work properly, you need to do:</p> <pre><code>public MyClass() { muplDefPdf = new MultiUploader(); setMuplDef(muplDefPdf, "pdf", onFinishUploaderHandlerPdf, onCancelUploaderHanderPdf); muplDefJpg = new MultiUploader(); setMuplDef(muplDefJpg, "jpg", onFinishUploaderHandlerJpg, onCancelUploaderHanderJpg); initWidget(uiBinder.createAndBindUi(this)); } </code></pre> <p>... and remove the <code>muplDef = new MultiUploader();</code> line inside the <code>setMuplDef</code> method.</p> |

7,135,252 | 0 | <p>By setting RightToLeft to Yes, you are asking the Windows text rendering engine to apply the text layout rules used in languages that use a right-to-left order. Arabic and Hebrew. Those rules are pretty subtle, especially because English phrases in those languages are not uncommon. It is not going to render "txeT emaN" as it normally does with Arabic or Hebrew glyphs, that doesn't make sense to anybody. It needs to identify sentences or phrases and reverse those. Quotes are special, they delineate a phrase.</p> <p>Long story short, you are ab-using a feature to get alignment that was <em>really</em> meant to do something far more involved. Don't use it for that.</p> |

13,763,076 | 0 | <p>There's a bug in your calculation: For <code>1000</code> activities and <code>200</code> resources, you don't have <code>200*1000</code> possible allocations but <code>200^1000</code> possible allocations (so more than <code>10^2000</code> possible allocations). Are you sure your optimization engine scales that much?</p> <p>Have you looked into doing resource allocation with <a href="http://docs.jboss.org/drools/release/5.5.0.Final/drools-planner-docs/html_single/index.html" rel="nofollow">Drools Planner</a> instead? Drools Planner can handle such allocation sizes and much bigger too. It searches for the best solution (and scales out well) and it uses Drools to calculate the score (= negative of the number of forbidden allocations) for each solution it evaluates.</p> |
6,086,670 | 0 | <p>In a DataTemplate, the DataContext is set by default to the item that is represented by the DataTemplate (in that case, the Car object). If the EditCar command is on the main viewmodel (which also contains the MyCars collection), you need to explicitly set the Source of the Binding to that object. This would be (assuming that you are using the MVVM Light's ViewModelLocator and that your VM is named Main) {Binding Source={StaticResource Locator}, Path=Main.EditCar}</p> <p>Cheers, Laurent</p> |

I'll try to explain:</p> <p>On the developer machine (PC1) the language setting is German(Germany). At the machine where the app is installed (PC2) the language was German(Austria). With these slight but important difference I got a FormatException when parsing a string to a double value at PC2 (',' <-> '.'). After changing the language settings at PC2 the issue was solved.</p> <p>Without remote debugging I wouldn't have detected this behaviour.</p> |
