  • Homework - C# - Creating an object instance with a button click

    - by Erica
    I'm new to learning Windows Programming with C#. My current assignment is to create a very simple bank account program: The user enters the accountholder name, account number and beginning balance, then presses a "Continue" button to work with that account by making deposits and withdrawals. I wrote a separate "BankAccount" class with the required data members and methods. I've put the code for the creation of the BankAccount object in the Continue button click event BankAccount currentAccount = new BankAccount(acctName, acctNum, beginningBalance); But that seems to make it local to that method only, and currentAccount is not recognized when I'm programming the click event for the "Record Transactions" (deposits and withdrawals) button. How and where should the creation of the BankAccount object be coded in order for it to be created when the "Continue" button is clicked and also recognized in the "Record Transactions" button click event? Please let me know if any clarification is needed, or if you need to see part or all of my code.

  • Is there a straightforward way to have a ThreadStatic instance member?

    - by Dan Tao
    With the ThreadStatic attribute I can have a static member of a class with one instance of the object per thread. This is really handy for achieving thread safety using types of objects that don't guarantee thread-safe instance methods (e.g., System.Random). It only works for static members, though. Is there some corresponding attribute that provides the same functionality, but for instance members? In other words, that allows me to have one instance of the object, per thread, per instance of the containing class?

  • Dangers of the pyton eval() statement

    - by LukeP
    I am creating a game. Specifically it is a pokemon battle simulator. I have an sqlite database of moves in which a row looks something like: name | type | Power | Accuracy | PP | Description However, there are some special moves. For said special moves, their damage (and other attributes not shown above, like status effects) may be dependant on certian factors. Rather than create a huge if/else in one of my classes covering the formulas for every one of these moves. I'd rather include another column in the DB that contains a formula in string form, like 'self.health/2'(simplified example). I could then just plug that into eval. I always see people saying to stay away from eval, but from what I can tell, this would be considered an acceptable use, as the dangers of eval only come into play when accepting user input. Am I correct in this assumption, or is there somthing i'm not seeing.

  • How do I move an Amazon micro instance to a small instance?

    - by Navetz
    I want to move my instance to a micro instance to a small instance but when I try to launch a new AMI based on my Micro instance AMI it only gives me the option for 64 bit instances. My initial ami is based off an ubuntu 10.04 image. Is it not possible to move between 64 bit and 32 bit instance? Would it be possible to use a load balancer to have a 32bit instance and a 64bit instance work together? I have a website/web app that I will be uploading huge volumes of data to. I will be starting with 65gigs of images and then moving up to 100+ gigs of images. I am not sure which instance type would be best for this. I was going to use a load balancer and auto scaling to increase the number of instance when the load is high. Also when using a load balancer, does one of the AMI instance become the primary image and the rest act as clones of it?

  • EMERGENCY - Major Problems After Perl Module Installed via WHM

    - by Russell C.
    I attempted to install the perl module Net::Twitter::Role::API::Lists using WHM and after doing so my whole site came down. It seems that something that was updated with the install isn't functioning correctly and since our website it written in Perl none of our site scripts will run. In almost 8 years of working with Perl I've never had any issues arise after installing a perl module so I have no idea how to even start troubleshooting. The error I see when trying to compile any of our Perl scripts is below. I'd appreciate any advice on what might be wrong and steps on how I can go about resolve it. Thanks in advance for your help!

  • Using EC2 instance as main development platform

    - by David
    My problem I am working as a consultant for various companies. Each company provides me with a laptop with their software on and I also have my own, where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the Large instance (cheapest 64-bit) for 8 hours a day for a year costs me 960$ per year, which is acceptable. I imagine that when I approach the workplace each day, I will make a single tap on my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you foresee?

  • How to load and pass a Xforms form in Orbeon (How to Send instance to XForms) ?

    - by Clem
    Hi, I am using the Orbeon Forms solution to generate messages from filled-in web forms. I read different code snippetse in Orbeon's wiki on XForms submission from a pipeline, and I tried different solutions but it doesn't work, and there is no example with a POST from a pipeline, caught by a PFC and sent to an XForms view that receives the posted data (all examples are done in the same page). I have the following pipeline which is received on his instance input: pipelineWrite.xpl <p:config ...> <p:param name="instance" type="input"/> <!-- instance containing the data of the form filled by user --> <p:param name="data" type="output"/> <p:processor name="oxf:java"> <!-- transforms the data into a file --> <p:input name="config"> <config sourcepath="." class="ProcessorWriteCUSDECCD001B"/> </p:input> <p:input name="input" href="#instance"/> <p:output name="output" id="file"/> <!-- XML containing the url of the file --> </p:processor> <p:processor name="oxf:xforms-submission"> <!-- post the XML to the success view --> <p:input name="submission"> <xforms:submission method="post" action="/CUSDECCD001B/success" /> </p:input> <p:input name="request" href="#file"/> <p:output name="response" ref="data"/> </p:processor> </p:config> Then there is the PFC which catch the actions : page-flow.xml <config xmlns="http://www.orbeon.com/oxf/controller"> <page path-info="/CUSDECCD001B/" view="View/ViewForm.xhtml"/> <!-- load the form to be filled in by user --> <page path-info="/CUSDECCD001B/write" model="Controller/PipelineWrite.xpl"/> <!-- send the instance of the form filled to the pipeline above --> <page path-info="/CUSDECCD001B/success" view="View/ViewSuccess.xhtml"/> <!-- send the instance containing the url of the file to the success view --> <epilogue url="oxf:/config/epilogue.xpl"/> </config> Then there is the success view, which is very simple : ViewSuccess.xhtml <html ... > <head> <title>Generation OK</title> <xforms:model> <xforms:instance id="FILE" src="input:instance"> <files xmlns=""> <file mediaType="" filename="" size="" /> </files> </xforms:instance> </xforms:model> </head> <body> Click here to download : <xforms:output ref="//file" appearance="xxforms:download"> <xforms:filename ref="@filename"/> <xforms:mediatype ref="@mediatype"/> <xforms:label>Download</xforms:label> </xforms:output> </body> </html> The problem is that the post is done well, the PFC catches the action well, load the correct view, but the view is loaded with no data (the view doesn't find the data on his instance input). I tried with a GET in the view to retrieve the POST data, and that's the same thing. No data is retrieved. So the download button doesn't work. I hope I'm clear enough to find a solution. Thanks in advance.

  • Inherit one instance variable from the global scope

    - by Julian
    I'm using Curses to create a command line GUI with Ruby. Everything's going well, but I have hit a slight snag. I don't think Curses knowledge (esoteric to be fair) is required to answer this question, just Ruby concepts such as objects and inheritance. I'm going to explain my problem now, but if I'm banging on, just look at the example below. Basically, every Window instance needs to have .close called on it in order to close it. Some Window instances have other Windows associated with it. When closing a Window instance, I want to be able to close all of the other Window instances associated with it at the same time. Because associated Windows are generated in a logical fashion, (I append the name with a number: instance_variable_set(self + integer, Window.new(10,10,10,10)) ), it's easy to target generated windows, because methods can anticipate what assosiated windows will be called, (I can recreate the instance variable name from scratch, and almost query it: instance_variable_get(self + integer). I have a delete method that handles this. If the delete method is just a normal, global method (called like this: delete_window(@win543) then everything works perfectly. However, if the delete method is an instance method, which it needs to be in-order to use the self keyword, it doesn't work for a very clear reason; it can 'query' the correct instance variable perfectly well (instance_variable_get(self + integer)), however, because it's an instance method, the global instances aren't scoped to it! Now, one way around this would obviously be to simply make a global method like this: delete_window(@win543). But I have attributes associated with my window instances, and it all works very elegantly. This is very simplified, but it literally translates the problem exactly: class Dog def speak woof end end def woof if @dog_generic == nil puts "@dog_generic isn't scoped when .woof is called from a class method!\n" else puts "@dog_generic is scoped when .woof is called from the global scope. See:\n" + @dog_generic end end @dog_generic = "Woof!" lassie = Dog.new lassie.speak #=> @dog_generic isn't scoped when .woof is called from an instance method!\n woof #=> @dog_generic is scoped when .woof is called from the global scope. See:\nWoof! TL/DR: I need lassie.speak to return this string: "@dog_generic is scoped when .woof is called from the global scope. See:\nWoof!" @dog_generic must remain as an insance variable. The use of Globals or Constants is not acceptable. Could woof inherit from the Global scope? Maybe some sort of keyword: def woof < global # This 'code' is just to conceptualise what I want to do, don't take offence! end Is there some way the .woof method could 'pull in' @dog_generic from the global scope? Will @dog_generic have to be passed in as a parameter?

  • EC2 instance store cloning or to ebs via gui management console

    - by devnull
    I have found similar questions here but the answer are either outdated or are from the command line. The case is this. I have an EC2 instance using instance store (this was the only AMI available for Debian 6 in Ireland). Now through the AWS GUI I can do a snapshot of the instance volume and/or even create a volume. But an image made from the snapshot doesn't boot. What is the best solution to either clone an EC2 instance that uses instance store OR from the created snapshot of the instance store to launch a new EBS instance (identical clone) FROM the gui aws management console and not command line ? Before turning this down consider that there is not similar question on how to do it via the aws management console. hint can't be done is not an appropriate answer. As you can create a snapshot of the instance store backed instance and/or a volume and create an AMI from that snapshot.

  • Unity: How to remove(unregister) registered instance from Unity mapping.

    - by bug0r
    Hello, I meet one problem that i can't solve now. I have the following: UnityHelper.DefaultContainer.RegisterInstance(typeof(IMyInterface), "test", instance); where UnityHelper.DefaultContainer is my helper for getting unity container with loaded configuration. here I registered instance as an instance of IMyInterface. So anywhere(some time after using) I want to remove this mapping. Remove it at all. How I can do it? I have tried UnityHelper.DefaultContainer.Teardown(instance) but is was unsuccessfull and the following code returns instance anyway. UnityHelper.DefaultContainer.ResolveAll() Any ideas? Thank you.

  • Purpose of Instance Methods vs. Class Methods in Objective-C

    - by qegal
    I have checked out all these questions... Difference Class and Instance Methods Difference between class methods and instance methods? Objective-C: Class vs Instance Methods? ...and all they explain is how instance methods are used on instances of a class and class methods are used with the class name, when a message is sent to a class object. This is helpful, but I'm curious to know why one would use a class method vs. an instance method. I'm fairly new to iOS application development, and usually use class methods, and I feel like I'm doing something wrong. Thanks in advanced!

  • greasemonkey: perform GM_xmlhttpRequest() from eval (follow up)

    - by Paul Tarjan
    How can you call GM_xmlhttpRequest inside of an eval where you are evaling some complicated code, some of which calls GM_xmlhttpRequest. This is a follow up to http://stackoverflow.com/questions/1074236 Here is some sample code: // ==UserScript== // @name Test GM AJAX // ==/UserScript== console = unsafeWindow.console; function fetch(msg) { console.log('fetching: '+msg); GM_xmlhttpRequest({ method: 'GET', url: 'http://google.com', onload: function(responseDetails) { console.log(msg); } }); } function complicated(arg1, arg2) { fetch(arg1 + arg2); } console.log('trying'); var code = 'complicated("Ya", "y!")'; function myEval(code) { eval(code); eval('setTimeout(function(){'+code+'},0)'); eval('setTimeout(fetch,0)'); eval('setTimeout(function(){console.log("here");fetch("cool")},0)'); fetch("BOO"); } myEval(code); which outputs: trying fetching: Yay! fetching: BOO fetching: Yay! fetching: 30 here fetching: cool BOO 30 So the only fetch that worked was the setTimeout(fetch,0) but I need to actually execute the code which includes come complicated code. Any ideas?

  • There is a Default instance of form in VB.Net but not in C#, WHY?

    - by Shekhar_Pro
    I'm just curious to know that there is The (Name) property, which represents the name of the Form class.This property is used within the namespace to uniquely identify the class that the Form is an instance of and, in the case of Visual Basic, is used to access the default instance of the form. Now where this Default Instance come from, why can't C# have a equivalent method to this. Also for example to show a form in C# we do something like this: //Only method Form1 frm = new Form1(); frm.Show(); But in VB.Net we have both ways to do it: //'First common method (used slash because editor wouldn't format it properly) Form1.Show(); //'Second method Dim frm as New Form1(); frm.Show(); My question comes from this first method. What is this Form1, is it an instance of Form1 or the Form1 class itself. Now as i mentioned above the Form name is the Default instance in VB.Net. But we also know that Form1 is a class defined in Designer so how can the names be same for both the Instance and class name. If Form1 is Class then there is no (Static\Shared) method named Show(). So where does this method come from. And finally why C# can't have an equivalent of this. If there some mistake in my question Please let me know *I've checked this on stackoverflow, but couldn't find an answer to this.If you do find then please give a link to it.*

  • SQL 2008 R2 Named Instance Client Connectivity Issues?

    - by Jerry Dodge
    We're upgrading our software from using SQL 2000 to 2008 R2. Our customers will be installing an update which uninstalls 2000 and installs 2008 R2 under the same instance. So if no instance existed, then no instance name will be set (default). However, the problem starts with the customers which have a named SQL instance. Starting in 2008 R2 (not sure of ones before), for some reason, a client connecting to the server by its instance name is unsuccessful. I'm testing from the Management Studio - if I can't connect this, then nothing can connect. I browse network servers, and find the specific server\instance in the list. But, upon trying to connect to an instance name like MyServer\INST, I get: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) I do in fact have TCP/IP and Named Pipes protocols enabled, this is the first thing I did. When I connect to the server using a comma (,) and port number like MyServer, 49195, it works just fine. So it appears that client computers are just unable to identify the instance names. This has happened on all our installations of SQL 2008 R2 and from all client computers, including Win 7, XP, Vista, Server 2008, and Server 2003. We never experienced such issues on earlier versions of SQL. The problem even persists if the firewalls and antiviruses are all disabled. Now, this is a large update which we will be distributing soon to all our customers, and we want to minimize the interaction they need with us to get this installed. We absolutely hate the idea of using a port number, because it will always be different, and we would have to modify each client to point to this server/port. Some of our customers may have hundreds of client computers. How do I make client connections to a named SQL instance work again? After all, this is the whole purpose of named instances, and if a client can't connect to this instance by its name, then what is it even named for? EDIT It was mentioned to make sure SQL Browser is running, so I checked, and it is running. The server is also able to connect to its self (locally) - just external connections are refused. UPDATE After more careful checking, I learned the firewall wasn't completely disabled when testing, and upon disabling it completely, this works. So it appears that SQL Browser is being blocked by the firewall from external clients from accessing.

  • Reverse-engineer SharePoint fields, content types and list instance—Part3

    - by ybbest
    Reverse-engineer SharePoint fields, content types and list instance—Part1 Reverse-engineer SharePoint fields, content types and list instance—Part2 Reverse-engineer SharePoint fields, content types and list instance—Part3 In Part 1 and Part 2 of this series, I demonstrate how to reverse engineer SharePoint fields, content types. In this post I will cover how to include lookup fields in the content type and create list instance using these content types. Firstly, I will cover how to create list instance and bind the custom content type to the custom list. 1. Create a custom list using list Instance item in visual studio and select custom list. 2. In the feature receiver add the Department content type to Department list and remove the item content type. C# AddContentTypeToList(web, “Department”, ” Department”); private void AddContentTypeToList(SPWeb web,string listName, string contentTypeName) { SPList list = web.Lists.TryGetList(listName); list.OnQuickLaunch = true; list.ContentTypesEnabled = true; list.Update(); SPContentType employeeContentType = web.ContentTypes[contentTypeName]; list.ContentTypes.Add(employeeContentType); list.ContentTypes["Item"].Delete(); list.Update(); } Next, I will cover how to create the lookup fields. The difference between creating a normal field and lookup fields is that you need to create the lookup fields after the lists are created. This is because the lookup fields references fields from the foreign list. 1. In your solution, you need to create a feature that deploys the list before deploying the lookup fields. 2. You need to write the following code in the feature receiver to add the lookup columns in the ContentType. C# //add the lookup fields SPFieldLookup departmentField = EnsureLookupField(currentWeb, “YBBESTDepartment”, currentWeb.Lists["DepartmentList"].ID, “Title”); //add to the content types SPContentType employeeContentType = currentWeb.ContentTypes["Employee"]; //Add the lookup fields as SPFieldLink employeeContentType.FieldLinks.Add(new SPFieldLink(departmentField)); employeeContentType.Update(true); private static SPFieldLookup EnsureLookupField(SPWeb currentWeb, String sFieldName, Guid LookupListID, String sLookupField) { //add the lookup fields SPFieldLookup lookupField = null; try { lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; } catch (Exception e) { } if (lookupField == null) { currentWeb.Fields.AddLookup(sFieldName, LookupListID, true); currentWeb.Update(); lookupField = currentWeb.Fields[sFieldName] as SPFieldLookup; lookupField.LookupField = sLookupField; lookupField.Group = “YBBEST”; lookupField.Required = true; lookupField.Update(); } return lookupField; }

  • EXALYTICS - If Oracle BI Server Does Not Fail Over to the TimesTen Instance

    - by Ahmed Awan
    If the BI Server does not fail over to the second TimesTen instance on the scaled-out node, then ensure that the logical table source (LTS) for the repository has mapped both TimesTen physical data sources. This mapping ensures that at the logical table source level, a mapping exists to both TimesTen instances. If one TimesTen instance is not available, then failover logic for the BI Server at the DSN level tries to connect to the other TimesTen instance.

  • Server 2008R2 in Extra Small Windows Azure Instance?

    - by Shawn Eary
    Windows Azure hosting for an Extra Small (XS) Windows VM seems to come out to be about $10 a month right now. I think this XS instance gives you the equivalent of a 1 GHZ CPU with 768MB of RAM. I think the minimum requirements for Server 2008 is 1GHZ CPU with 512MB of RAM. Also, I think the minimum requirements for SQL Server Express is 1GHZ CPU with 256 MB of RAM and that the minimum requirements for Team Foundation Server Express 11 Beta is 2.2 GHZ CPU with 1 Gig of RAM (this 2.2 GHZ part could be a problem for my 1 GHZ XS VM...). Given the performance of the XS Azure instance, would I be able to install: a very basic MVC web site; a free instance of SQL Server Express; a free single user instance of Team Foundation Server Express 11 Beta and run the XS VM instance without serious crashing? I know there are other Shared WebHost providers that can provide these features for me, but those hosting providers have the following disadvantages: They sometimes cost a lot of money after all of the "addons" are in place They probably don't provide the level of security and employee integrity that Microsoft can provide They don't provide the total control that an Azure VM seems to provide

  • Using EC2 instance as main development platform

    - by David
    My problem I am working as a consultant for various companies. Each company provides me with a laptop where with their software on and I also have my own where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also sometimes spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the High-CPU On-Demand Instances (medium) for 8 hours a day for a year costs me 580$, which is acceptable. I imagine that when I approach the workplace each day, I will make a single click my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you forsee?
