I haven’t personally come across a desire to constrain the types within data types I’ve created, but it’s not obvious to me why the language designers “decided it was a bad idea to allow”. Why is that? Because it was misleading and worked completely backwards from what would actually be useful. In particular, it didn’t … Read more
dtoa.c contains two main functions: dtoa(), which converts a double to string, and strtod(), which converts a string to a double. It also contains a lot of support functions, most of which are for its own implementation of arbitrary-precision arithmetic. dtoa.c’s claim to fame is getting these conversions right, and that can only be done, … Read more
When making calls to a contentservice script I always have sent a callback for JSONP. Since GAS does not support CORS this is the only reliable way to ensure your app doesn’t break when x-domain issues arrive. Making a call in jQuery just add “&callback=?”. It will figure everything else out. var url = “https://script.google.com/macros/s/{YourProjectId}/exec?offset=”+offset+”&baseDate=”+baseDate+”&callback=?”; … Read more
As you can see, it’s cutting everything off the url from the ampersand escape code and after. From the documentation of the characters() method: The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into … Read more
If you only want to highlight the cells with the text from the TextBox you could make an AttatchedProperty for the DataGrid to accept your search value from the TextBox and create another AttatchedProperty for the Cell to indicate a match that you can usee to set properties in the Cell style. Then we create … Read more
You can extend RangeReplaceableCollection, constrain its elements to Equatable and declare your method as mutating. If you want to return Bool in case the appends succeeds you can also make the result discardable. Your extension should look like this: extension RangeReplaceableCollection where Element: Equatable { @discardableResult mutating func appendIfNotContains(_ element: Element) -> (appended: Bool, memberAfterAppend: … Read more
You can use lookarounds, e.g: string[] tests = { “AutomaticTrackingSystem”, “XMLEditor”, }; Regex r = new Regex(@”(?!^)(?=[A-Z])”); foreach (string test in tests) { Console.WriteLine(r.Replace(test, ” “)); } This prints (as seen on ideone.com): Automatic Tracking System X M L Editor The regex (?!^)(?=[A-Z]) consists of two assertions: (?!^) – i.e. we’re not at the beginning … Read more
The next version of Eclipse (3.5, due next June) has an option to include all necessary jars. It was introduced in 3.5M5 (thanks, basszero). Or you can try to build your project with Maven 2. Then, you can build a “fat” jar with mvn assembly:assembly. Another option is to use ant. Unpack all JAR files … Read more
Try using P/Invoke to call InternetGetConnectedState. That should tell you whether or not you have a connection configured. You can then try checking the specific connection to your service using InternetCheckConnection. This is (sometimes) quicker than hooking up the connection directly, but I’d test it to see if it’s any better than just doing a … Read more
