• zsh auto-complete event designator

  - by simont

  (See my previous question for additional context). I'm migrating to zsh from bash, and using oh-my-zsh. When my zsh history looks something like the following: git status git add -A git commit I want to be able to re-run git add -A. To do that, I could use !?git add, which should: !?str[?] Refer to the most recent command containing str. The trailing ‘?’ is necessary if this reference is to be followed by a modifier or followed by any text that is not to be considered part of str. The link for zsh event designators is here. Unfortunately, I can't do this - as I'm typing !?git add, as I hit the ' ', it auto-completes the command to the most recent command matching git (ie, it auto-completes with git commit). I can't use the event designator properly because of this auto-completion as I hit the space. I assume this is an oh-my-zsh feature. I have no idea where to look, though - greping for 'complet' in the oh-my-zsh source doesn't get me anywhere. My question: how do I turn off this feature? Or, if that's not something that's known, where should I be looking - if I was going to implement this auto-complete when whitespace is entered, where would be a logical place to do so in the oh-my-zsh framework?

• auto-mounting shared folders in VirtualBox

  - by brannerchinese

  I am writing to ask what the effect of the auto-mounting process is in VirtualBox, and where the folders can be accessed within a guest Linux system if auto-mount is used. I have VirtualBox 4.0.4 installed on Mac OS 10.6.7, with Guest Additions apparently running correctly. The guest OS is Ubuntu 10.04, and I observe no apparent problems with it. I find that if the shared folders have "auto-mount" unchecked in the VirtualBox settings, they can then be mounted using the prescribed syntax sudo mount -t vboxsf folder_name path_to_mount_point and all works as it is supposed to. But if the auto-mount option is checked, then I find that I can no longer mount the shared folders manually. I get the error mounting failed with the error: Invalid argument and the folders also do not appear to mount anywhere else accessible to me. Using the syntax sudo mount -t vboxsf without specifying a path installs them in /media, with their names prefixed with sf_, but they are not easily accessible there and I have not been able to change their owner using chown, either. Thanks for your patient explanation.

• How to take advantage of an auto-property when refactoring this .Net 1.1 sample?

  - by Hamish Grubijan

  I see a lot of legacy .Net 1.1-style code at work like in example below, which I would like to shrink with the help of an auto-property. This will help many classes shrink by 30-40%, which I think would be good. public int MyIntThingy { get { return _myIntThingy; } set { _myIntThingy = value; } } private int _myIntThingy = -1; This would become: public int MyIntThingy { get; set; } And the only question is - where do I set MyIntThingy = -1;? If I wrote the class from the start, then I would have a better idea, but I did not. An obvious answer would be: put it in the constructor. Trouble is: there are many constructors in this class. Watching the initialization to -1 in the debugger, I see it happen (I believe) before the constructor gets called. It is almost as if I need to use a static constructor as described here: http://www.c-sharpcorner.com/uploadfile/cupadhyay/staticconstructors11092005061428am/staticconstructors.aspx except that my variables are not static. Java's static initializer comes to mind, but again - my variables are not static. http://www.glenmccl.com/tip_003.htm I want to make stylistic but not functional changes to this class. As crappy as it is, it has been tested and working for a few years now. breaking the functionality would be bad. So ... I am looking for shorter, sweeter, cuter, and yet EQUIVALENT code. Let me know if you have questions.

• How can I make XAnalogTV fill my screen?

  - by Breakthrough

  I recently installed xscreensaver, as well as the additional/extra screensavers. Many of the OpenGL ones function correctly, going fullscreen as expected. However, for some reason, the XAnalogTV screensaver leaves two "blank" spots on the edges of my screen. If I manually launch XAnalogTV, it displays a window, which it fills correctly. When I maximize the window, the same effect occurs: the window maximizes, but the two edges of the screen are literally "transparent". This effect also occurs when the screensaver is set to fullscreen. For these reasons, I believe the problem may be related to the aspect ratio of the screen. The edges of the screen are literally "ignored", with nothing being drawn there. Specifically, note the transition between the maximized and full-screen screenshots (with the un-drawn whitespace shrinking as the vertical height has been increased). For reference, I am running Xubuntu 12.04 on a Dell Vostro 1520 (Intel P8600, Nvidia 9300M) with a 1440 x 900 display (16:10). I have also set the GetViewPortIsFullOfLies preference to true. Is there any way to force XAnalogTV to fill my entire screen? Relevant screenshots (windowed, maximized, and full-screen, respectively):

• Auto-hydrate your objects with ADO.NET

  - by Jake Rutherford

  Recently while writing the monotonous code for pulling data out of a DataReader to hydrate some objects in an application I suddenly wondered "is this really necessary?" You've probably asked yourself the same question, and many of you have: - Used a code generator - Used a ORM such as Entity Framework - Wrote the code anyway because you like busy work     In most of the cases I've dealt with when making a call to a stored procedure the column names match up with the properties of the object I am hydrating. Sure that isn't always the case, but most of the time it's 1 to 1 mapping.  Given that fact I whipped up the following method of hydrating my objects without having write all of the code. First I'll show the code, and then explain what it is doing.      /// <summary>     /// Abstract base class for all Shared objects.     /// </summary>     /// <typeparam name="T"></typeparam>     [Serializable, DataContract(Name = "{0}SharedBase")]     public abstract class SharedBase<T> where T : SharedBase<T>     {         private static List<PropertyInfo> cachedProperties;         /// <summary>         /// Hydrates derived class with values from record.         /// </summary>         /// <param name="dataRecord"></param>         /// <param name="instance"></param>         public static void Hydrate(IDataRecord dataRecord, T instance)         {             var instanceType = instance.GetType();                         //Caching properties to avoid repeated calls to GetProperties.             //Noticable performance gains when processing same types repeatedly.             if (cachedProperties == null)             {                 cachedProperties = instanceType.GetProperties().ToList();             }                         foreach (var property in cachedProperties)             {                 if (!dataRecord.ColumnExists(property.Name)) continue;                 var ordinal = dataRecord.GetOrdinal(property.Name);                 var isNullable = property.PropertyType.IsGenericType &&                                  property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>);                 var isNull = dataRecord.IsDBNull(ordinal);                 var propertyType = property.PropertyType;                 if (isNullable)                 {                     if (!string.IsNullOrEmpty(propertyType.FullName))                     {                         var nullableType = Type.GetType(propertyType.FullName);                         propertyType = nullableType != null ? nullableType.GetGenericArguments()[0] : propertyType;                     }                 }                 switch (Type.GetTypeCode(propertyType))                 {                     case TypeCode.Int32:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt32(ordinal), null);                         break;                     case TypeCode.Double:                         property.SetValue(instance,                                           (isNullable && isNull) ? (double?) null : dataRecord.GetDouble(ordinal),                                           null);                         break;                     case TypeCode.Boolean:                         property.SetValue(instance,                                           (isNullable && isNull) ? (bool?) null : dataRecord.GetBoolean(ordinal),                                           null);                         break;                     case TypeCode.String:                         property.SetValue(instance, (isNullable && isNull) ? null : isNull ? null : dataRecord.GetString(ordinal),                                           null);                         break;                     case TypeCode.Int16:                         property.SetValue(instance,                                           (isNullable && isNull) ? (int?) null : dataRecord.GetInt16(ordinal), null);                         break;                     case TypeCode.DateTime:                         property.SetValue(instance,                                           (isNullable && isNull)                                               ? (DateTime?) null                                               : dataRecord.GetDateTime(ordinal), null);                         break;                 }             }         }     }   Here is a class which utilizes the above: [Serializable] [DataContract] public class foo : SharedBase<foo> {     [DataMember]     public int? ID { get; set; }     [DataMember]     public string Name { get; set; }     [DataMember]     public string Description { get; set; }     [DataMember]     public string Subject { get; set; }     [DataMember]     public string Body { get; set; }            public foo(IDataRecord record)     {         Hydrate(record, this);                }     public foo() {} }   Explanation: - Class foo inherits from SharedBase specifying itself as the type. (NOTE SharedBase is abstract here in the event we want to provide additional methods which could be overridden by the instance class) public class foo : SharedBase<foo> - One of the foo class constructors accepts a data record which then calls the Hydrate method on SharedBase passing in the record and itself. public foo(IDataRecord record) {      Hydrate(record, this); } - Hydrate method on SharedBase will use reflection on the object passed in to determine its properties. At the same time, it will effectively cache these properties to avoid repeated expensive reflection calls public static void Hydrate(IDataRecord dataRecord, T instance) {      var instanceType = instance.GetType();      //Caching properties to avoid repeated calls to GetProperties.      //Noticable performance gains when processing same types repeatedly.      if (cachedProperties == null)      {           cachedProperties = instanceType.GetProperties().ToList();      } . . . - Hydrate method on SharedBase will iterate each property on the object and determine if a column with matching name exists in data record foreach (var property in cachedProperties) {      if (!dataRecord.ColumnExists(property.Name)) continue;      var ordinal = dataRecord.GetOrdinal(property.Name); . . . NOTE: ColumnExists is an extension method I put on IDataRecord which I’ll include at the end of this post. - Hydrate method will determine if the property is nullable and whether the value in the corresponding column of the data record has a null value var isNullable = property.PropertyType.IsGenericType && property.PropertyType.GetGenericTypeDefinition() == typeof (Nullable<>); var isNull = dataRecord.IsDBNull(ordinal); var propertyType = property.PropertyType; . . .  - If Hydrate method determines the property is nullable it will determine the underlying type and set propertyType accordingly - Hydrate method will set the value of the property based upon the propertyType   That’s it!!!   The magic here is in a few places. First, you may have noticed the following: public abstract class SharedBase<T> where T : SharedBase<T> This says that SharedBase can be created with any type and that for each type it will have it’s own instance. This is important because of the static members within SharedBase. We want this behavior because we are caching the properties for each type. If we did not handle things in this way only 1 type could be cached at a time, or, we’d need to create a collection that allows us to cache the properties for each type = not very elegant.   Second, in the constructor for foo you may have noticed this (literally): public foo(IDataRecord record) {      Hydrate(record, this); } I wanted the code for auto-hydrating to be as simple as possible. At first I wasn’t quite sure how I could call Hydrate on SharedBase within an instance of the class and pass in the instance itself. Fortunately simply passing in “this” does the trick. I wasn’t sure it would work until I tried it out, and fortunately it did.   So, to actually use this feature when utilizing ADO.NET you’d do something like the following:        public List<foo> GetFoo(int? fooId)         {             List<foo> fooList;             const string uspName = "usp_GetFoo";             using (var conn = new SqlConnection(_dbConnection))             using (var cmd = new SqlCommand(uspName, conn))             {                 cmd.CommandType = CommandType.StoredProcedure;                 cmd.Parameters.Add(new SqlParameter("@FooID", SqlDbType.Int)                                        {Direction = ParameterDirection.Input, Value = fooId});                 conn.Open();                 using (var dr = cmd.ExecuteReader())                 {                     fooList= (from row in dr.Cast<DbDataRecord>()                                             select                                                 new foo(row)                                            ).ToList();                 }             }             return fooList;         }   Nice! Instead of having line after line manually assigning values from data record to an object you simply create a new instance and pass in the data record. Note that there are certainly instances where columns returned from stored procedure do not always match up with property names. In this scenario you can still use the above method and simply do your manual assignments afterward.

• Clear Fillable Online PDF Files

  - by May

  I filled in an online pdf form. After I finished, I closed the window thinking that the form will clear itself since I didn't save it. When I went back to the website and clicked on the form again, it still had the information that I entered. Other than manually deleting all the information on the form, is there another way of clearing the form?

• Fill CSS box with text from MySQL till there is no overflow, scrollbar, or hidden text

  - by terrance branigan

  I want to fill a CSS box with text till there is no overflow or scrollbar. I fetch text from MySQL. The user clicks a button and the next bit of text that can fit will fill the box. The only way I've figured to do this is by parsing through the text and counting characters and newlines, etc and calculating whether it will fit in the box. Is there an easier way to do this? Thank you

• Spring validation errors not displayed

  - by Art Vandelay

  I have the following situation. I have a validator to validate my command object and set the errors on a Errors object to be displayed in my form. The validator is invoked as expected and works okay, but the errors i set on the Errors objects are not displayed, when i am sent back to my form because of the validation errors. Validator: public void validate(Object obj, Errors err) { MyCommand myCommand = (MyCommand) obj; int index = 0; for (Field field : myCommand.getFields()) { if (field.isChecked()) { if ((field.getValue() == null) || (field.getValue().equals(""))) { err.rejectValue("fields[" + index + "].value", "errors.missing"); } } index++; } if (myCommand.getLimit() < 0) { err.rejectValue("limit", "errors.invalid"); } } Command: public class MyCommand { private List<Field> fields; private int limit; //getters and setters } public class Field { private boolean checked; private String name; private String value; //getters and setters } Form: <form:form id="myForm" method="POST" action="${url}" commandName="myCommand"> <c:forEach items="${myCommand.fields}" var="field" varStatus="status"> <form:checkbox path="fields[${status.index}].checked" value="${field.checked}" /> <c:out value="${field.name}" /> <form:input path="fields[${status.index}].value" /> <form:errors path="fields[${status.index}].value" cssClass="error" /></td> <form:hidden path="fields[${status.index}].name" /> </c:forEach> <fmt:message key="label.limit" /> <form:input path="limit" /> <form:errors path="limit" cssClass="error" /> </form:form> Controller: @RequestMapping(value = REQ_MAPPING, method = RequestMethod.POST) public String onSubmit(Model model, MyCommand myCommand, BindingResult result) { // validate myCommandValidator.validate(myCommand, result); if (result.hasErrors()) { model.addAttribute("myCommand", myCommand); return VIEW; } // form is okay, do stuff and redirect } Could it be that the paths i give in the validator and tag are not correct? The validator validates a command object containing a list of objects, so that's why i give a index on the list in the command object when registering an error message (for example: "fields["+index+"]".value). Or is it that the Errors object containing the errors is not available to my view? Any help is welcome and appreciated, it might give me a hint or point me in right direction.

• Mechanize form submit not going to the correct response page, no errors as to why. Something I'm doing?

  - by Zack Shapiro

  I threw this all in one controller for testing purposes. My code fills out the form correctly for adding a new address to your Amazon account. There are two buttons that submit this form, one takes you to add a new address which is what I don't want, and the other is just a Save & Continue input/image. When I submit the form via that button, as I do below, the form is still on the page, filled out as I have with my code. Inspecting the page titles, they're the same. There are no discernible errors that Mechanize or Amazon spit back. Any ideas? class AmazonCrawler def initialize @agent = Mechanize.new do |agent| agent.user_agent_alias = 'Mac Safari' agent.follow_meta_refresh = true agent.redirect_ok = true end end def login # login_url = "https://www.amazon.com/ap/signin?_encoding=UTF8&openid.assoc_handle=usflex&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.mode=checkid_setup&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.max_auth_age=0&openid.return_to=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fcss%2Fhomepage.html%3Fie%3DUTF8%26ref_%3Dgno_yam_ya" login_url = "https://www.amazon.com/gp/css/account/address/view.html?ie=UTF8&ref_=ya_add_address&viewID=newAddress" @agent.get(login_url) form = @agent.page.forms.first form.email = "[email protected]" form.radiobuttons.first.value = "0" form.radiobuttons.last.check form.password = "my_password" dashboard = @agent.submit(form) end end class UsersController < ApplicationController def index response = AmazonCrawler.new.login form = response.forms[1] # fill out form form.enterAddressFullName == "Your Name" form.enterAddressAddressLine1 = "123 Main Street" form.enterAddressAddressLine2 = "Apartment 34" form.enterAddressCity = "San Francisco" form.enterAddressStateOrRegion = "CA" form.enterAddressPostalCode = "94101" form.enterAddressPhoneNumber = "415-555-1212" form.AddressType = "RES" new_response = form.submit( form.button_with(value: /Save.*Continue/) ) end end

• Proper application shutdown before windows xp auto shutdown

  - by vashman

  I frequently leave the computer on playing a movie or downloading a file while I go to bed. I do use the 'shutdown computer when finished' feature of KMPlayer or getright or uTorrent or whatever program I am using. This method effectively shuts down the computer, but the problem is that there are some applications that seem to exit forcefully when doing this kind of shutdown, this being clearly reflected in winamp not saving the current playlist and config, messenger not saving the chat logs, etc. My goal here would be to have automatically close properly all applications when the auto/scheduled program triggers it. I am looking for some Windows shutdown mode/setting that does application closing like the user would do. I am not expecting to auto-click on save dialogs prompts, if this is needed I will do it before leaving the computer on for auto shutdown.

• How to make Excel's "Auto Fit Row Height" feature actually auto fit the row height?

  - by DanM

  For every generation of Excel I can remember (including 2010, which I'm using now), Excel's "Auto Size Row" features sometimes fails to actually auto size a row when the cell contains wrapped text. When it works properly, all the text is revealed and there is no additional space below the last line of text. When it fails, it adds extra space below the text. To make matters worse, what you see is not always what you get, i.e., text that appeared okay on screen gets cut off when it's printed. You also get different sizing depending on whether you are zoomed in/out or at actual size. Simple test case: Why is there a one-line gap after the text in cell A1 but in A2? (I double-checked that I applied Auto Fit Row Height to both rows. Zoom level is 100%.) Is there any known remedy for this without resorting to manually adjusting the row heights (which is not practical for more than a handful of rows)?

• Firefox "auto-complete" is very slow

  - by netvope

  Firefox version: 3.6 My places.sqlite is rather big (114MB, after being optimized by SpeedyFox.) If I turn on auto-complete, it may take 1 or 2 seconds for Firefox to accept a newly typed URL. To reproduce the issue: Type a URL into the URL bar, press enter. Nothing happens, and Firefox consumes 100% CPU (actually 50% of 2 cores) for 1 to 2 seconds Then Firefox start the network connection and load the webpage. Since it consumes 100% CPU, I don't think the bottleneck is the disk. I have some experience with SQLite and I know a 100MB DB is very small. To achieve the delay Firefox must be doing some expensive processing or inefficient queries. The issue does not appear if: auto-complete is turned off, or the URL is frequently used, or a new profile with no history is used Does anyone have any idea how to solve the problem? Should I file this as a bug? I don't want to give up my 100MB history, but I don't want to give up auto-complete either :)

• Set certain WSUS updates to auto-install

  - by Nicolas

  We're running a WSUS server for the simple purpose of caching updates. Since we are a very small network of all "power users", we've got the domain group policy for WSUS updates on the clients set to prompt for download/install. i.e. We don't want updates to install without our knowledge. But there are a few cases where it would be nice to be able to set a certain update to auto-install. e.g. Windows Defender updates, Malicious Software Removal Tool, Outlook Junk Email Filter, etc. Basically all the silly little updates that you would always install anyway and don't require a restart. Is there a way to set the general policy to prompt for download/install, but auto-install certain regular updates? P.S. WSUS itself does have the facility to auto-approve certain updates. That part works. Facts & Figures: SBS 2003 domain Windows 7 Pro clients Windows XP Pro clients

• Google Chrome auto-clicker extension?

  - by Joel Murphy

  I'm looking for an auto-clicker that will auto click page elements in Google Chrome. Standard auto-clickers work fine, but I'd like to continue working on my computer without having to keep Google Chrome open. Does anyone know of any extensions that offer this functionality? Anything that allows me to specify an element to be clicked on, or set screen co-ordinates within a webpage and will click away until I decide to stop the script would be perfect. I've tried looking at macro extensions, but they don't seem to offer the functionality I want. Can anybody suggest a particular extension? Thanks in advance.
