• Receiving Text From Another Application

  - by Garry

  Hi, I'm building some home automation software with Cocoa/Objective-C. The main application will have a minimal GUI and will most likely be represented by a status bar icon only. I'm using proprietary speech-to-text software (MacSpeech Dictate) that takes my voice command and converts it to plain text. I then need to send this plain text to my app for parsing. Is there a way to send a string to a Cocoa application? Could AppleScript achieve this? How would I make the NSString string in my app "available" to receive the passed string? For reasons that are beyond the scope of this question - it is not possible to dictate the command directly into my app. Many thanks in advance,

• Copy Paste is Disabled in Property Grid

  - by ofarooq

  Hi All, I have a FileNameEditor inside a property grid, which has a few entries like Main File : "C:\blah1" Sec File: "C:\blah2" and so on. My problem is that I cannot copy and paste from one property entry to another, and I cannot type in the fields manually as well. Is there a specific property that will enable editing inside the FileNameEditor. Example public class MyEditor : FileNameEditor { public override bool GetPaintValueSupported(ITypeDescriptorContext context) { return false; } public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value) { object e = base.EditValue(context, provider, value); if ((value as MyFileS) != null) { (value as MyFilesS).FileName = (String) e; } return e; } protected override void InitializeDialog(OpenFileDialog openFileDialog) { base.InitializeDialog(openFileDialog); } } Thanks

• .NET assembly in GAC + Config

  - by Dante

  I have a .NET 3.5 assembly, a DAL, that connects to a database through Linq2SQL. I deploy this assembly in the GAC as it can be used by multiple business layers. The question is: in a dev environment I have a connection string different than the one in the production environment. Before deploying the assembly to the prod GAC I need to recompile it with the appropriate connection string. Is there any way to allow deploying the assembly to the GAC independently of the connection string, being that info read from some config? Thx in advance

• Is this bad style of programming(C#) ?

  - by m0s

  Hi, so in my program I have parts where I use try catch blocks like this try { DirectoryInfo dirInfo = new DirectoryInfo(someString); //I don't know if that directory exists //I don't know if that string is valid path string... it could be anything //Some operations here } catch(Exception iDontCareWhyItFailed) { //Didn't work? great... we will say: somethings wrong, try again/next one } Of course I probably could do checks to see if the string is valid path (regex), then I would check if directory exists, then I could catch various exceptions to see why my routine failed and give more info... But in my program it's not really necessary. Now I just really need to know if this is acceptable, and what would a pro say/think about that. Thanks a lot for attention.

• Why have private fields in data contracts modified through public ones?

  - by Nordvind

  When you make a new WCF project, sample service is generated for you. The default data contract is (I've just changed the string type field title): [DataContract] public class CompositeType { bool boolValue = true; string name = ""; [DataMember] public bool BoolValue { get { return boolValue; } set { boolValue = value; } } [DataMember] public string Name { get { return name; } set { name = value; } } } What is the point of having those private fields boolValue and name? Is it a good practice writing some data sanitizing or some other manipulations in contract, thus bloating it? It seems the only sane reason for me not writing to fields directly. So is it a bloatware or it has some reason behind it?

• How to ignore an exception and continue processing a foreach loop?

  - by Barry Dysert

  I have a test program that is supposed to loop over all the files under C:. It dies when it hits the "Documents and Settings" folder. I'd like to ignore the error and keep looping over the remaining files. The problem is that the exception is thrown in the foreach, so putting a try/catch around the foreach will cause the loop to exit. And putting a try/catch after the foreach never fires (because the exception is thrown in the foreach). Is there any way to ignore the exception and continue processing the loop? Here's the code: static void Main(string[] args) { IEnumerable<string> files = Directory.EnumerateFiles(@"C:\", "*.*", SearchOption.AllDirectories); foreach (string file in files) // Exception occurs when evaluating "file" Console.WriteLine(file); }

• Javascript 'class' and singleton problems

  - by Kucebe

  I have a singleton object that use another object (not singleton), to require some info to server: var singleton = (function(){ /*_private properties*/ var myRequestManager = new RequestManager(params, //callbacks function(){ previewRender(response); }, function(){ previewError(); } ); /*_public methods*/ return{ /*make a request*/ previewRequest: function(request){ myRequestManager.require(request); //err:myRequestManager.require is not a func }, previewRender: function(response){ //do something }, previewError: function(){ //manage error } }; }()); This is the 'class' that make the request to the server function RequestManager(params, success, error){ //create an ajax manager this.param = params; this._success = success; //callbacks this._error = error; } RequestManager.prototype = { require: function(text){ //make an ajax request }, otherFunc: function(){ //do other things } } The problem is that i can't call myRequestManager.require from inside singleton object. Firebug consolle says: "myRequestManager.require is not a function", but i don't understand where the problem is. Is there a better solution for implement this situation?

• What is the correct method to load an XML file and re-write it as a CVS? (C# Only)

  - by codesmack

  Hello, I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named and within the car element I need to process the element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C# Thank you, CodeSmack

Maybe indentation is wrong?

• How do I use comma-separated-value file received from a URL query in Objective-c?

  - by chiemekailo

  How do I use comma-separated-value file received from a URL query in Objective-c? when I query the URL I get csv such as "OMRUAH=X",20.741,"3/16/2010","1:52pm",20.7226,20.7594. How do I capture and use this for my application? My problem is creating/initializing that NSString object in the first place. An example is this link "http://download.finance.yahoo.com/d/quotes.csv?s=GBPEUR=X&f=sl1d1t1ba&e=.csv" which returns csv. I dont know how to capture this as an object since I cannot use an NSXMLParser object.

• XML Processing on iPhone: What is the best option?

  - by gonso

  Hello Im building a new version of an iPhone application and Im wondering if I should review how my app communicates with the server. My iPhone client sends and receives XML over HTTP requests. To send the information I use ASIHTTPRequest framework. I "manually" build the XML request by appending strings. To parse the response Im using a NSXMLParser. My question is if I have better options to A) Create an XML string from a memory object. B) Create a memory object from the XML string. Is there anything like JAXB to marshal XML into object? Thanks Gonso

• How to catch a moment when the external editor of TOLEContainer has been closed?

  - by Andrew

  Borland Developer Studio 2006, Delphi: I have a TOLEContainer object with AllowInPlace=False. When the external editor is closed and changed my OLE object I have to do something with this OLE object inside TOLeContainer. The problem is I can't catch a moment when the external editor is closed. OnDeactivate event is not working. Probably I should change the source code of TOLEContainer adding this event myself, but I don't know where is the best place for it. Can you advice some method?

• python dictionary with constant value-type

  - by s.kap

  hi there, I bumped into a case where I need a big (=huge) python dictionary, which turned to be quite memory-consuming. However, since all of the values are of a single type (long) - as well as the keys, I figured I can use python (or numpy, doesn't really matter) array for the values ; and wrap the needed interface (in: x ; out: d[x]) with an object which actually uses these arrays for the keys and values storage. I can use a index-conversion object (input -- index, of 1..n, where n is the different-values counter), and return array[index]. I can elaborate on some techniques of how to implement such an indexing-methods with reasonable memory requirement, it works and even pretty good. However, I wonder if there is such a data-structure-object already exists (in python, or wrapped to python from C/++), in any package (I checked collections, and some Google searches). Any comment will be welcome, thanks.

• How can I make this Dictionary TryGetValue code more readable?

  - by mafutrct

  I'd like to test if an id was not yet known or, if it is known, if the associated value has changed. I'm currently using code similar to this, but it is hard to understand for those not familiar with the pattern. Can you think of a way to make it more readable while keeping it short in LOC? string id; string actual; string stored; if (!someDictionary.TryGetValue (id, out stored) || stored != actual) { // id not known yet or associated value changed. }

• Bash: any command to replace strings in text files?

  - by mikez302

  I have a hierarchy of directories containing many text files. I would like to search for a particular text string every time it comes up in one of the files, and replace it with another string. For example, I may want to replace every occurrence of the string "Coke" with "Pepsi". Does anyone know how to do this? I am wondering if there is some sort of Bash command that can do this without having to load all these files in an editor, or come up with a more complex script to do it. I found this page explaining a trick using sed, but it doesn't seem to work in files in subdirectories.

• Displaying text in UILabel in iPhone

  - by SeniorLee

  OK. What's wrong with my code? - (void)viewDidLoad { [super viewDidLoad]; lblResult = [UILabel alloc]; } - (void)viewWillAppear:(BOOL)animated { lblResult.text = @"BlahBlah"; } I linked lblResult to Label object in IB well. But the label only shows the default text. Where's my BlahBlah?? And when the default string I set in the IB actually set to lblResult?? The reason that BlahBlah string is not displyed is I guess because lblResult.text is over-written by default string specified from IB. Just my guess. Can anyone make me clear with that?

• Active Index is not being persisted in jQuery accordion change event

  - by Xaisoft

  I have an asp.net aspx page and on that page I have a hidden input field with and id of paneIndex. However, when I load the page, the alert shows index 1 which is correct on the first load, but if I open up pane 3 for example, the alert shows 1 still. Am I doing something wrong? In a Custom.js file, I have the following code: $(document).ready(function() { $("#accordion").accordion({ active: 1, collapsible: true, autoHeight: false, change: function(event, ui) { var activeIndex = $("#accordion").accordion('option', 'active'); $("#paneIndex").val(activeIndex); //alert(activeIndex); } }); }); In my server side button click, I have the following code: string activeIndex = Request.Form["paneIndex"]; string script = string.Format(@"<script type=""text/javascript"">var paneIndex = {0};</script>", activeIndex); if(!ClientScript.IsStartupScriptRegistered("JSScript")) ClientScript.RegisterStartupScript(this.GetType(),"JSScript", script);

• Hibernate and Child Objects (add versus clear)

  - by tyndall

  Lets say I have domain model with Automobile and Wheels. Wheels is a List of Wheels Wheels has a many-to-one relationship to Automobile. If I get an object back from Hibernate and it has 4 wheels. I take that object remove the 4 wheels and add 4. And then Save. If I ask Hibernate for the object again and it returns an auto with 8 wheels... what are we doing wrong? I don't have access to the source for a few days but want to give our Java devs a push in the right direction. Thanks.

• Django template context not working with imported class

  - by Andy Hume

  I'm using Django's templating on appengine, and am having a problem whereby a class I'm importing from another package is not correctly being made available to the template context. Broadly speaking, this is the code. The prop1 is not available in the template in the first example below, but is in the second. MyClass is identical in both cases. This does not work: from module import MyClass context = MyClass() self.response.out.write(template.render(path, context)) This does: class MyClass(object): def __init__(self): self.prop1 = "prop1" context = MyClass() self.response.out.write(template.render(path, context)) If I log the context in the above code I get: <module.MyClass object at 0x107b1e450> when it's imported, and: <__main__.MyClass object at 0x103759390> when it's defined in the same file. Any clues as to what might cause this kind of behaviour?

• Config file format

  - by Felics

  Hello, does anyone knows a file format for configuration files easy to read by humans? I want to have something like tag = value where value may be: String Number(int or float) Boolean(true/false) Array(of String values, Number values, Boolean values) Another structure(it will be more clear what I mean in the fallowing example) Now I use something like this: IntTag=1 FloatTag=1.1 StringTag="a string" BoolTag=true ArrayTag1=[1 2 3] ArrayTag2=[1.1 2.1 3.1] ArrayTag3=["str1" "str2" "str3"] StructTag= { NestedTag1=1 NestedTag2="str1" } and so on. Parsing is easy but for large files I find it hard to read/edit in text editors. I don't like xml for the same reason, it's hard to read. INI does not support nesting and I want to be able to nest tags. I also don't want a complicated format because I will use limited kind of values as I mentioned above. Thanks for any help.

• JQuery+Java setting field value with val() + single quote

  - by Fabio K

  I have a problem setting the value of a textarea element with jquery's val(). Basically, I have a JSP file which receives a string parameter called 'text'. Java code: String text = (String) request.getParameter('text'); Now I want my textarea element to receive this text: Javascript code: $('#textarea_id').val('<%=text%>'); It works when my text doesnt contain quotes single quotes (and possibly other chars). For example, for text = test' this error happens: Uncaught SyntaxError: Unexpected token ILLEGAL $('#textarea_id').val('test''); I hope you guys understand. I need a way to encode this value... i tried using escape so the quote is replaced by %27, but after unescaping its replaced again and the error happens. Thanks!

• FindControl table cell

  - by rlb.usa

  I want to reference a table cell via it's string ID in my code like this FindControl("tdAnswer_a") because I am manipulating string ID names. The ASPX code looks like this : <table>...<td ID="tdAnswer_a" runat="server" visible="true"> But FindControl is not able to find the table cell. When I reference it by ID like this : tdAnswer_a.Visible = true; in my codebehind, it has no problems. (This is not part of a repeater or gridview). How can I FindControl my table cells via string ID names?

• Urban Airship Tags issue

  - by Moshe

  I modified the alias sample code from: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"alias\": \"%@\"}", self.deviceAlias] dataUsingEncoding:NSUTF8StringEncoding]]; to: [request addRequestHeader: @"Content-Type" value: @"application/json"]; [request appendPostData:[[NSString stringWithFormat: @"{\"tags\": \"%@\"}", offsetStr] dataUsingEncoding:NSUTF8StringEncoding]]; offsetStr is a string containing a Timezone offset (which can be any number between -12 and 12). For some reason, Urban Airship is making each character of the string into its own tag. I've tried to substitute the - for a string neg with the same results. What's wrong?
