  • Should Python import statements always be at the top of a module?

    - by Adam J. Forster
    PEP 08 states: Imports are always put at the top of the file, just after any module comments and docstrings, and before module globals and constants. However if the class/method/function that I am importing is only used in rare cases, surely it is more efficient to do the import when it is needed? Isn't this: class SomeClass(object): def not_often_called(self) from datetime import datetime self.datetime = datetime.now() more efficient than this? from datetime import datetime class SomeClass(object): def not_often_called(self) self.datetime = datetime.now()

  • delphi vs c# post returns different strings - utf problem?

    - by argh
    I'm posting two forms - one in c# and one in delphi. But the result string seems to be different: c# returns: ¤@@1@@@@1@@@@1@@xsm˱Â0Ð... delphi returns: #$1E'@@1@@@@1@@@@1@@x'#$009C... and sice both are compressed streams I'm getting errors while trying to decompress it... The C# is 'correct' - ie. extracts. I'm not an expert on delphi - I just need to convert some piece of code from c# to delphi. c# code: string GetData(Hashtable aParam, string ServerURL) { string Result = ""; WebRequest Request = HttpWebRequest.Create(ServerURL); Request.Method = "POST"; Request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8"; UTF8Encoding encUTF8 = new System.Text.UTF8Encoding(false); StreamWriter writer = new StreamWriter(Request.GetRequestStream(), encUTF8); foreach (DictionaryEntry element in aParam) { writer.Write(element.Key + "=" + element.Value + "&"); } writer.Close(); writer.Dispose(); WebResponse Response = Request.GetResponse(); StreamReader Reader = new StreamReader(Response.GetResponseStream(), System.Text.Encoding.Default); Result = Reader.ReadToEnd(); Reader.Close(); Response.Close(); Reader.Dispose(); return Result; } delphi code: function GetData(aParam:TStringList; ServerURL:string):string; var req: TIdHTTP; res: string; begin req := TIdHTTP.Create(); with req do begin Request.ContentType := 'application/x-www-form-urlencoded; charset=UTF-8'; Request.Method := 'POST'; Request.CharSet := 'utf-8'; Request.AcceptCharSet := 'utf-8'; res := Post(ServerURL, aParam); end; Result := res; req.Free; end; -edit- I'm using delphi 2010

  • What are the requirments for ISupportInitialize code to be serialized in InitializeComponent? .Net

    - by Jules
    I need to add some code to the EndInit method of a PictureBox control but unfortunately its private and, from what I can gather, I can't shadow it and call base - at least not in VB.Net. What I can do is add a dummy property to my picture box class. The type of the dummy property is simply a class that just implements ISupportInitialize. However, that doesn't work, I need the dummy class to inherit from Control. Is that the minimum requirement?

  • Add methods to generated WCF client proxy code

    - by dcstraw
    I'd like to add one additional method for each service operation in my WCF client proxy code (i.e. the generated class that derives from ClientBase). I have written a Visual Studio extension that has an IOperationContractGenerationExtension implementation, but this interface only seems to expose the ability to modify the service interface, not the ClientBase-derived class. Is there any way to generate new methods in the proxy client class?

  • Disable AND Grey out an eclipse widget

    - by Fredrik
    I have a org.eclipse.swt.widgets.Composite that I want to be able to enable/disable programatically. The org.eclipse.swt.widgets.Control.setEnabled(boolean enabled) method works fine, but it does not give any visual information that the widget(s) are disabled. What I would like to do is to have the disabled state mean the widgets are greyed out. Right now they just enter a weird state where the user is unable to click or perform any action on them.

    I'm converting from C# this LINQ expression. However, it does not seem to work. C# return (from w in fishSticks group w by w.FishQty into g orderby g.Key descending select g).First().First(); VB Return (From w In fishSticks Group w By w.FishQty Into g() Order By g.Key Descending Select g).First().First() Visual Studio turns g into g() itself and then gives me this error: Definition of method 'g' is not accessible in this context. Any ideas?

  • Java IDE - find all INDIRECT usages/references of a function or class?

    - by GreenieMeanie
    In Netbeans or in Eclipse, you can use "Find Usages" or "References" from the right click context menu. If a() calls b(), using the functionality from b() will show you a(). However, what I want is to be able to see some kind of tree or have an option to see all usages of a given/class or method, such that if z() calls a() that using the functionality will show both z() and a(). Any IDE plugins or external tools that can do this?
