• Java: how to get mercurial current changeset number for use in program

  - by Rabarberski

  I've recently started using mercurial for version control in a Java project. When I run my program, the input parameters it has used to produce certain a output, are written to a specific file. It would be nice if I could add the current mercurial changeset number (indicating the version of my program) to that output file as well. What would be the easiest way to do so on Windows? I could write a simple Java parser to fetch the output of the first line of the hg log -l 1 command, but perhaps there is an easier way (i.e., less code lines)?

• 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);

• How to manage different form contexts of same form element in single DOM tree

  - by nimp

  Hi, As my question title could be bit unclear to you (I tried best), following is what I'm exactly trying to do. I'm having a form element (say a user_info form), where such form elements will be generated for different users by java script and displayed in different js tabs (example: dojo tabs). once form elements are generated, later I need to react on user actions performed on different html elements defined inside user_info form. In this case I need to identify what is the context (in which user_info form element) in which user is working on. The simplest example would be how to retrieve form id of the form in which user actions are being performed. According to my understanding, I can not simply retrieve from by form id, because now DOM tree contains duplicate form instances of the same from element. So, IS there anyway, I could identify form context based on the user actions on its input elements. Thank You.

• Mixing expressions and expression language (<%= %> inside of c:if)

  - by Jack

  I need to access some constants in my jsp, and sadly the EL does not offer any functionality for it. There are some options like the unstandard tag library, but I'd like to keep it a bit more standard. I tried: <%@ page import = "com.jackdane.Constants"%> <c:if test="${object.display == '<%=com.jackdane.Constants.YES %>}'"> //some display logic </c:if> But that doesn't appear to do the trick. It's been a while since I've used an expression so I might have made an error. Any input is appreciated. Edit: To clarify, the constants class is not in my control. It's inside a jar file that I recieved. It contains no getters/setters. Just private static final Strings.

• Send JSON object via GET and POST without having to wrapping it in another object literal, and manag

  - by Kucebe

  My site does some short ajax call in JSON format, using jQuery. At client-side i'd like to send object just passing it in ajax function, without being forced to wrap it in an object literal like this: {'person' : person}. For the same reasons, at server-side i'd like to manage objects without the binding of $_GET['person'] or $_POST['person']. For example: var person = { 'name' : 'John', 'lastName' : 'Doe', 'age' : 32, 'married' : true } sendAjaxRequest(person); in php, using: $person = json_decode(file_get_contents("php://input")); i can get easily the object, but only with POST format, not in GET. Any suggestions?

• How to change the range of a chart in Excel using VBA?

  - by Pieter

  Hi guys, I'm using an Excel sheet to keep track of a particular time series (my daily weight, if you must know). I created a macro that inserts a row, automatically adds today's date and calculates a moving average based on my input. There is also a chart to visualize my progress. I have tried recording a macro that updates the time series in the graph, but to no success. How can I create a macro or VBA script that, when executed, updates the range of the graph from A(x):Cy to A(x-1):Cy to include today's measurement? Thanks!

• WebUIView is very slow

  - by Shamil

  Hello, I'm building a custom RSS reader app with incorporated feed link view (UIWebView). Using the following code, when the view, containing WebUIView is loaded, it takes about 6 seconds before anything is outputted to the user: -(void)viewDidLoad{ [super viewDidLoad]; NSString *urlString = [[[self appDelegate] currentlySelectedBlogItem]linkUrl]; NSURL *url = [NSURL URLWithString:urlString]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [_webview loadRequest:requestObj]; [_webview setScalesPageToFit:YES]; } Any ideas why UIWebView is being so slow? I've checked the URL input, it's clean and what I'd expect it to be. I'm building for iOS 3.0 as base deployment target.

• Extract dates from filename

  - by Newbie

  I have a situation where I need to extract dates from the file names whose general pattern is [filename_]YYYYMMDD[.fileExtension] e.g. "xxx_20100326.xls" or x2v_20100326.csv The below program does the work //Number of charecter in the substring is set to 8 //since the length of YYYYMMDD is 8 public static string ExtractDatesFromFileNames(string fileName) { return fileName.Substring(fileName.IndexOf("_") + 1, 8); } Is there any better option of achieving the same? I am basically looking for standard practice. I am using C#3.0 and dotnet framework 3.5 Edit: I have like the solution and the way of answerig of LC. I have used his program like string regExPattern = "^(?:.*_)?([0-9]{4})([0-9]{2})([0-9]{2})(?:\\..*)?$"; string result = Regex.Match(fileName, @regExPattern).Groups[1].Value; The input to the function is : "x2v_20100326.csv" But the output is: 2010 instead of 20100326(which is the expected one). Can anyone please help.

• What are the advantages and disadvantages of plug-in based architecture?

  - by RP

  I want to do the architectural design for a software that can be used integrate various third party software’s (executable) under one platform. Standard project types will be added to the platform by default. The project type defines the way in which the different software will be executed and their input and output files. The user can customize the available standard project type and that will be added to the platform as new project type which defines new custom execution flow. Also it should support easy extension and customization of the features. I read that plug-in based architecture supports both. What are the advantages and disadvantages of plug-in based architecture? Do we have any better architecture which can be used for this kind of scenario? Thanks in advance:)

• I'd like to preview a Word document on form.

  - by Tychumsempir

  I'm writing a VB program that fills in values within a word document. I'm utilizing the Microsoft Word 12.0 Object Library as a Reference. I'd like to provide a scrollable preview pane to my user that is within the form he or she is using. It would be even cooler if the user could edit the document through this pane. I've done Interop extensively, so I'm well aware of how to write and edit a Word document. I just want to put it into a frame and preview it. I'll probably try to select around the document based on what is changing as the user provides input so they can see what's being changed and where. Thoughts? Thanks

• form submits in FireFox when any button on page is clicked

  - by RememberME

  First time using Asp.net-mvc and originally followed the NerdDinner tutorial. My form submit button looks like this: <p> <input type="submit" value="Save" /> </p> I've now added another button to the page with jQuery code attached. It works in IE, but when I test in FireFox the form submits. I tried adding another button, this time with no attached jQuery code and the same thing happens. When the button is clicked, the form submits. <button id="random-button">Do Nothing</button> ??

• Performing regex on a stream

  - by takoi

  I have some large text files which im going to preform consecutive matching on (just capturing, not replacing). Im thinking its not such a good idea to keep the whole file in memory, but rather use a Reader. What i know about the input is that if there's a match, its not going to span more than 5 lines. So my idea was to have some sort of buffer which just keeps these 5 lines, or so, do the first search, and continue. But it has to "know" where the regex match ended for this to work. e.g if the match ends at line 2 it should start the next search from here. Is it possible to do something like this in an efficient way?

• Regex to *not* match any characters

  - by Erick

  I know it is quite some weird goal here but for a quick and dirty fix for one of our system we do need to not filter any input and let the corruption go into the system. My current regex for this is "\^.*" The problem with that is that it does not match characters as planned ... but for one match it does work. The string that make it not work is ^@jj (basically anything that has ^ ... ). What would be the best way to not match any characters now ? I was thinking of removing the \  but only doing this will transform the "not" into a "start with" ...

  - by jpjp

  I want to make a textbook where it starts out as a given width/height. Then if users type more then the given amount of space, the textbox expands downward. How do I go about doing this?

• SQL Server 2008 + expensive union all

  - by Tim Mahy

  Hi al, we have 5 tables over which we should query with user search input throughout a stored procedure. We do a union all of the similar data inside a view. Because of this the view can not be materialized. We are not able to change these 5 tables drastically (like creating a 6th table that contains the similar data of the 5 tables and reference that new one from the 5 tables). The query is rather expensive / slow what are our other options? It's allowed to think outside the box. Unfortunately I cannot give more information like the table/view/SP definition because of customer confidentiality... greetings, Tim

• Extract IP address from an html string (python)

  - by GoJian

  My Friends, I really want to extract a simple IP address from a string (actually an one-line html) using Python. But it turns out that 2 hours passed I still couldn't come up with a good solution. >>> s = "<html><head><title>Current IP Check</title></head><body>Current IP Address: 165.91.15.131</body></html>" -- '165.91.15.131' is what I want! I tried using regular expression, but so far I can only get to the first number. >>> import re >>> ip = re.findall( r'([0-9]+)(?:\.[0-9]+){3}', s ) >>> ip ['165'] In fact, I don't feel I have a firm grasp on reg-expression and the above code was found and modified from elsewhere on the web. Seek your input and ideas!
