  • jQuery issue with anchor tag using jqTransform

    - by James Helms
    I'm using jqtransform on my site. When the user is on a for them to be able to use hot keys to move through the selections. I added this function: $wrapper.find('a').keydown(function (e) { var Esc = 27; var code = (e.keyCode ? e.keyCode : e.which); if(code== Esc || (code>=65 &&code<=90)){ var letter = String.fromCharCode(code); if (code==Esc) keyCodes = ""; else{ if (keyCodes=='') keyCodes += letter; else keyCodes += letter.toLowerCase(); var item = $wrapper.find('a[text^=\'' + keyCodes + '\']:first'); item.click(); } } }); inside of $.fn.jqTransSelect. This code works fine in all browsers but IE. the only thing i can find is that IE doesn't like the click event. Can anyone please help me with this? If i debug into the code I can see that item is a select not an anchor like i would expect it to be, and that confuses me even more.

  • How should I launch a Portable Python Tkinter application on Windows without ugliness?

    - by Andrew
    I've written a simple GUI program in python using Tkinter. Let's call this program 'gui.py'. My users run 'gui.py' on Windows machines from a USB key using Portable Python; installing anything on the host machine is undesirable. I'd like my users to run 'gui.py' by double-clicking an icon at the root of the USB key. My users don't care what python is, and they don't want to use a command prompt if they don't have to. I don't want them to have to care what drive letter the USB key is assigned. I'd like this to work on XP, Vista, and 7. My first ugly solution was to create a shortcut in the root directory of the USB key, and set the "Target" property of the shortcut to something like "(root)\App\pythonw.exe (root)\App\gui.py", but I couldn't figure out how to do a relative path in a windows shortcut, and using an absolute path like "E:" seems fragile. My next solution was to create a .bat script in the root directory of the USB key, something like this: @echo off set basepath=%~dp0 "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" This doesn't seem to care what drive letter the USB key is assigned, but it does leave a DOS window open while my program runs. Functional, but ugly. Next I tried a .bat script like this: @echo off set basepath=%~dp0 start "" "%basepath%App\pythonw.exe" "%basepath%\App\gui.py" (See here for an explanation of the funny quoting) Now, the DOS window briefly flashes on screen before my GUI opens. Less ugly! Still ugly. How do real men deal with this problem? What's the least ugly way to start a python Tkinter GUI on a Windows machine from a USB stick?

  • Minimal assembler program for CP/M 3.1 (z80)

    - by Andrew J. Brehm
    I seem to be losing the battle against my stupidity. This site explains the system calls under various versions of CP/M. However, when I try to use call 2 (C_WRITE, console output), nothing much happens. I have the following code. ORG 100h LD E,'a' LD C,2 CALL 5 CALL 0 I recite this here from memory. If there are typos, rest assured they were not in the original since the file did compile and I had a COM file to start. I am thinking the lines mean the following: Make sure this gets loaded at address 100h (0h to FFh being the zero page). Load ASCII 'a' into E register for system call 2. Load integer 2 into C register for system call 2. Make system call (JMP to system call is at address 5 in zero page). End program (Exit command is at address 0 in zero page). The program starts and exits with no problems. If I remove the last command, it hangs the computer (which I guess is also expected and shows that CALL 0 works). However, it does not print the ASCII character. (But it does print an extra new line, but the system might have done that.) How can I get my CP/M program to do what the system call is supposed to do? What am I doing wrong?

  • ASP.NET ListView, custom DataSources, and editing items

    - by Andrew Shepherd
    The MSDN walkthroughs provide a number of examples where you can drag a DataSource from the toolbox, run through some simple configuration steps, then drag a ListView onto the screen, point it at the DataSource, and hey - you've got full table editing. Now I'm trying to write my own DataSource class (a class that implements System.Web.UI.IDataSource) and my own DataSourceView class. I now assign an instance of this custom DataSource class to the ListView.DataSource propery. The display of all the items is working well. However, updating, inserting and deleting just is not working. I'm overriding every function I can in my DataSourceView class, and they just aren't being called. This is such a huge topic, I'll focus this question on one simple example: When you press the "Edit" button (the button inside the ItemTemplate with a CommandName of "Edit", you expect the ItemTemplate to be replaced by an EditItemTemplate. This did not happen. The only way I could get it to happen was to handle the onitemediting event. protected void _listViewPublicHolidays_ItemEditing(object sender, ListViewEditEventArgs e) { _listViewPublicHolidays.EditIndex = e.NewEditIndex; _listViewPublicHolidays.DataBind(); } This is hardly a problem, but how come I had to do it at all? In the MSDN walkthroughs where I attach a ListView to a LinqDataSource, this code doesn't have to be written. Can someone who's been here before hazard a guess as to what would be different or missing in my custom datasource?

  • Customizing the TFS 2008 build sequence to avoid compilation and deploy SSRS

    - by Andrew
    I'm trying to create a CI process for SQL Server Reporting Services. I am fairly new to TFS but quite experienced with MSBuild. In the past I've used a combination of MSBuild with Team City so the whole build process is more or less custom. Here lies the start of my problems, as the solution I am deploying only contains Report Server projects (rds), no compilation is required. I thought that I would override the the first default task that TFS runs (EndToEndIteration) to override the default TFS build sequence and inject my own. The first snag that I have come across is that the build always fails, how can I set the status of the build to success? Currently the EndToEndIteration task is very light and only has a message. Is this the best method to create a custom build process in TFS where compilation is not required? Or should I use the default sequence and override one of the hook tasks mentioned in http://msdn.microsoft.com/en-us/library/aa337604%28VS.80%29.aspx (ie: AfterCompile) The core steps that I'd like to achieve are: Bundle the RDL and datasource files Connect to the host server to register/deploy the reports Re-apply any subscriptions that previously existed Run tests to verify the deployment succeeded and is returning results as expected I have found another article on Report services deployment: http://stackoverflow.com/questions/88710/reporting-services-deployment But it doesn't mention the best practice for customizing the standard build process. Any help would be appreciated.

  • How does the iPhone SDK Core Data system store date types to sqlite?

    - by Andrew Arrow
    I used core data to do this: NSManagedObjectContext *m = [self managedObjectContext]; Foo *f = (Foo *)[NSEntityDescription insertNewObjectForEntityForName:@"Foo" inManagedObjectContext:m]; f.created_at = [NSDate date]; [m insertObject:f]; NSError *error; [m save:&error]; Where the created_at field is defined as type "Date" in the xcdatamodel. When I export the sql from the sqlite database it created, created_at is defined as type "timestamp" and the values look like: 290902422.72624 Nine digits before the . and then some fraction. What is this format? It's not epoch time and it's not julianday format. Epoch would be: 1269280338.81213 julianday would be: 2455278.236746875 (notice only 7 digits before the . not 9 like I have) How can I convert a number like 290902422.72624 to epoch time? Thanks!

  • Change cell color in Excel according to adjacent dropdown value

    - by Andrew Heath
    I understand how to make a dropdown list. I understand how to make conditional formatting change the color of a cell. What I do not understand is how to make conditional formatting change the color of a cell based solely on the state of another cell (not a comparison). A1 is a No / Yes dropdown list B1 is a criteria statement If the user satisfies the criteria statement in B1, they select Yes on the dropdown list in A1. For quick reference, if possible, I'd like B1 to change to a green background color on this event... and of course change back to no-fill if the dropdown is reset to No. Is this possible in Excel 2003 and/or 2007?

  • Open Source Project & Language Selection

    - by James
    I'm getting ready to start an open-source project that will target .NET/Mono. For those who have started their own open source venture... Do you let the fact that a project is going to be open-source weigh on the decision of what language to use? For example. Most .NET open-source projects are written in C#. However, if you were more comfortable with VB.NET, Boo, Nemerle, etc... would you use it? What other considerations are there? This particular project will be a core library and application for geocaching. Similar to GSAK.

  • IgnoreArguments including an Action<T>

    - by James L
    I'm probably missing something obvious here, so apologies in advance! Using Rhino Mocks, how do I set an expectation that a method taking an Action will be called, but I want to use IgnoreArguments. Obviously I can't specify null as that isn't an Action, and I dont want any meaningless code in the test. As I said, it's probably obvious by the syntax is eluding me at the moment!

  • Posting an image and textual based data to a wcf service

    - by James Hay
    I have a requirement to write a web service that allows me to post an image to a server along with some additional information about that image. I'm completely new to developing web services (normally client side dev) so I'm a little stumped as to what I need to look into and try. How do you post binary data and plain text into a servic? What RequestFormat should I use? It looks like my options are xml or json. Can I use either of these? Bit of a waffly question but I just need some direction rather than a solution as I can't seem to find much online.

    I am trying to copy all data from worksheet1 and paste the values into worksheet2 at the same position I am using office 2003 and the Interlop library. Here is my code; public void CreateExcelWorksheet() { Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); if (xlApp == null) { Console.WriteLine("EXCEL could not be started.

  • How can I create Wikipedia's footnote highlighting solely with jQuery

    - by andrew.bachman
    I would like to duplicate Wikipedia's footnote highlighting from in-text citation click solely in jQuery and CSS classes. I found a webpage that describes how to do so with CSS3 and then a JavaScript solution for IE. I would like however to do so solely with jQuery as the site I'm doing it on already has a bunch of jQuery elements. I've come up with a list of the process. In-Text Citation Clicked Replace highlight class with standard footnote class on <p> tag of footnotes that are already highlighted. Add highlight to the appropriate footnote Use jQuery to scroll down the page to appropriate footnote. I've come up with some jQuery so far but I'm extremely new to it relying heavy on tutorials and plugins to this point. Here is what I have with some plain English for the parts I haven't figured out yet. $('.inlineCite').click(function() { $('.footnoteHighlight').removeClass('footnoteHighlight').addClass('footnote'); //add highlight to id of highlightScroll //scroll to footnote with matching id }); If I had a method to pass a part of the selector into the function and turn it into a variable I believe I could pull it off. Most likely I'm sure one of you gurus will whip something up that puts anything I think I have done to shame. Any help will be greatly appreciated so thank you in advance. Cheers.

  • Creating a [materialised]view from generic data in Oracle/Mysql

    - by Andrew White
    I have a generic datamodel with 3 tables CREATE TABLE Properties ( propertyId int(11) NOT NULL AUTO_INCREMENT, name varchar(80) NOT NULL ) CREATE TABLE Customers ( customerId int(11) NOT NULL AUTO_INCREMENT, customerName varchar(80) NOT NULL ) CREATE TABLE PropertyValues ( propertyId int(11) NOT NULL, customerId int(11) NOT NULL, value varchar(80) NOT NULL ) INSERT INTO Properties VALUES (1, 'Age'); INSERT INTO Properties VALUES (2, 'Weight'); INSERT INTO Customers VALUES (1, 'Bob'); INSERT INTO Customers VALUES (2, 'Tom'); INSERT INTO PropertyValues VALUES (1, 1, '34'); INSERT INTO PropertyValues VALUES (2, 1, '80KG'); INSERT INTO PropertyValues VALUES (1, 2, '24'); INSERT INTO PropertyValues VALUES (2, 2, '53KG'); What I would like to do is create a view that has as columns all the ROWS in Properties and has as rows the entries in Customers. The column values are populated from PropertyValues. e.g. customerId Age Weight 1 34 80KG 2 24 53KG I'm thinking I need a stored procedure to do this and perhaps a materialised view (the entries in the table "Properties" change rarely). Any tips?

  • How to optimize this user ranking query

    - by James Simpson
    I have 2 databases (users, userRankings) for a system that needs to have rankings updated every 10 minutes. I use the following code to update these rankings which works fairly well, but there is still a full table scan involved which slows things down with a few hundred thousand users. mysql_query("TRUNCATE TABLE userRankings"); mysql_query("INSERT INTO userRankings (userid) SELECT id FROM users ORDER BY score DESC"); mysql_query("UPDATE users a, userRankings b SET a.rank = b.rank WHERE a.id = b.userid"); In the userRankings table, rank is the primary key and userid is an index. Both tables are MyISAM (I've wondered if it might be beneficial to make userRankings InnoDB).

  • Storing dates as UTC in database

    - by James
    I am storing date/times in the database as UTC and computing them inside my application back to local time based on the specific timezone. Say for example I have the following date/time: 01/01/2010 00:00 Say it is for a country e.g. UK which observes DST (Daylight Savings Time) and at this particular time we are in daylight savings. When I convert this date to UTC and store it in the database it is actually stored as: 31/12/2009 23:00 As the date would be adjusted -1 hours for DST. This works fine when your observing DST. However, what happens when the clock is adjusted back? When I pull that date from the database and convert it to local time that particular datetime would be seen as 31/12/2009 23:00 when in reality it was processed as 01/01/2010 00:00. Correct me if I am wrong but isn't this a bit of a flaw when storing times as UTC?

  • C# WebBrowser Invoke issue

    - by James Jeffrey
    I am logging into facebook using a web browser. Everything works, but the problem is when I invoke the button click I need to check if the password is correct but, the check seems to happen before the button is invoked which makes no sense at all because the checking code is after the invoke. private void Facebook_Login(String username, String password) { webBrowser1.Url = new Uri("http://m.facebook.com"); while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection inputs = webBrowser1.Document.GetElementsByTagName("input"); foreach(HtmlElement input in inputs) { if (input.GetAttribute("name") == "email") { input.SetAttribute("value", "[email protected]"); } if (input.GetAttribute("name") == "pass") { input.SetAttribute("value", "kelaroostj"); // dont worry that pass wont work lol. } if (input.GetAttribute("name") == "login") { input.InvokeMember("click"); } } while (webBrowser1.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); HtmlElementCollection bs = webBrowser1.Document.GetElementsByTagName("b"); foreach(HtmlElement b in bs) { MessageBox.Show(b.InnerHtml); } Log_Message("Logged into Facebook with: [email protected]"); }

  • NHibernate. DTO -> Domain

    - by Andrew Kalashnikov
    Hello guys. I've got SOA which processing data for diff clients(asp,sl). The base of this design is domains of my business model. For transporting,showing it to clients I use DTO. For mapping domain to DTO I use AutoMapper. Now I should persist new entities from clients. I want use my DTO's at this scenario too. So i've got some questions as I'm not much familiar with this design 1) Is it a good practice build DTO on client and send it to web-service on the wire? MayBe i should pass my domains? 2) Is it possible have several DTO's to one domain (one show at grid, and one to save). For saving I need set all nonprimitive props at client. 3) DTO - to Domain. If I've got int can I use AutoMapper to generate NHibernate Proxy for this ID, or I should do i manually. Your expierence and practice are very interesting. Thanks for answer!!!

  • Use database field maxlength as html layout input maxlength best practice. asp.net mvc

    - by Andrew Florko
    Hello everybody, There are string length limitations in database structure (email is declared as nvarchar[30] for instance) There are lots of html forms that has input textbox fields that should be limited in length for that reason. What is the best practice to synchronize database fields and html layout input fields length limitations ? Can it be done automatically (html layout input fields declared the same max length as database data they represent)? Thank you in advance.

  • Implicit vs explicit getters/setters in AS3, which to use and why?

    - by James
    Since the advent of AS3 I have been working like this: private var loggy:String; public function getLoggy ():String { return loggy; } public function setLoggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc... this.loggy = loggy; } and have avoided working like this: private var _loggy:String; public function get loggy ():String { return loggy; } public function set loggy ( loggy:String ):void { // checking to make sure loggy's new value is kosher etc... this.loggy = loggy; } I have avoided using AS3's implicit getters/setters partly so that I can just start typing "get.." and content assist will give me a list of all my getters, and likewise for my setters. I also dislike underscores in my code which turned me off the implicit route. Another reason is that I prefer the feel of this: whateverObject.setLoggy( "loggy's awesome new value!" ); to this: whateverObject.loggy = "loggy's awesome new value!"; I feel that the former better reflects what is actually happening in the code. I am calling functions, not setting values directly. After installing Flash Builder and the great new plugin SourceMate ( which helps to get some of the useful features that FDT is famous into FB ) I realized that when I use SourceMate's "generate getters and setters" feature it automatically sets my code up using the implicit route: private var _loggy:String; public function get loggy ():String { return loggy; } public function set loggy ( loggy:String ):void { // do whatever is needed to check to make sure loggy is an acceptable value this.loggy = loggy; } I figure that these SourceMate people must know what they are doing or they wouldn't be writing workflow enhancement plugins for coding in AS3, so now I am questioning my ways. So my question to you is: Can anyone give me a good reason why I should give up my explicit g/s ways, start using the implicit technique, and embrace those stinky little _underscores for my private vars? Or back me up in my reasons for doing things the way that I do?
