  • How to replace the nth column/field in a comma-separated string using sed/awk?

    - by Peter Meier
    assume I have a string "1,2,3,4" Now I want to replace, e.g. the 3rd field of the string by some different value. "1,2,NEW,4" I managed to do this with the following command: echo "1,2,3,4" | awk -F, -v OFS=, '{$3="NEW"; print }' Now the index for the column to be replaced should be passed as a variable. So in this case index=3 How can I pass this to awk? Because this won't work: echo "1,2,3,4" | awk -F, -v OFS=, '{$index="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{$($index)="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{\$$index="NEW"; print }' Thanks for your help!

  • Show extra info for Preference screens when CheckboxPreference summary field is not enough long?

    - by Pentium10
    I have situation when you can enabled/disable modules for my Android application. For this I use a CheckboxPreference screen. This is all good, but the summary field gets cut off if longer descriptions are added than 2 lines. Suppose I have 4-5 lines of description available for each module, I would like to display this in a helper window. I tried to bind a click event to the CheckboxPreference, but that fires for the whole line, so not only when the checkbox is clicked, and more, where ever you click on the line the checkbox is toggled. So now I am wondering if this can be fixed. So if the user needs more info, just taps the text and the helper opens up, and if want to toggle the settings it taps the checkbox. How would you do it? I am open to other ideas too, if they do work.

  • when i merge a data table with a typed dataset, one single field on a single row is DBNull sometimes

    - by benj007
    Hi everybody, I have a strange problem sometimes when I try to merge a data table with a typed dataset my data table is filled in with a stored procedure and when I checked the content of this table it is ok, everything is in there straight after I merge it with my core typed dataset like this : MyTypedDataSet.TheTable.Clear(); MyTypedDataSet.TheTable.Merge(MyDataTable); and now if i check the table in the dataset everything is ok except only one single field on one single row which is DBNull, that makes no sense because the source data table contains the good integer vaue. Thanks a lot in advance guys :)

  • Filling in a multi-choice field in a Sharepoint Doc-Lib using SetDocsMetaInfo Frontpage Server Extentions RPC method

    - by notnot
    I've been given a big chunk of code which eventually calls upon the SetDocsMetaInfo method from Frontpage Server Extension RPC. This is easy enough for most document uploading and property updating, except when dealing with multichoice fields. I've been scouring through MSDN and I can't find anything on how to fill in multiple values for such a field. The general syntax for properties is something like this: [SR|default], with the type (string in this case) followed by a pipe and then the value to be written. Does anyone know the syntax for multichoice fields? references: MSDN: SetDocsMetaInfo

  • Is it OK to mixed NumberLong and normal integers in the same field in MongoDB?

    - by Nicholas Tolley Cottrell
    I have been using Morphia to persistent objects from Java. I have also been running some batch processes from the console. I just realised that some values are now stored as NumberLong and number as plain Javascript numbers. I have an index on this field. Everything seems to be ok, but if I query: {f: 100} from the console it still returns the object even if it actually contains {f: NumberLong(100)} Is this true of all the drivers? It is best practice to avoid NumberLong is I can fit the value inside 32-bit? Will I save a lot of data and index space if I convert all NumberLongs to basic numbers?

  • In C# how can I serialize a List<int> to a byte[] in order to store it in a DB field?

    - by Matt
    In C# how can I serialize a List to a byte[] in order to store it in a DB field? I know how to serialize to a file on the disk, but how do I just serialize to a variable? Here is how I serialized to the disk: List<int> l = IenumerableofInts.ToList(); Stream s = File.OpenWrite("file.bin"); BinaryFormatter bf = new BinaryFormatter(); bf.Serialize(s, lR); s.Close(); I'm sure it's much the same but I just can't wrap my head around it.

  • Why will this for loop not return one field from list rather than the list?

    - by Dick Eshelman
    import csv """sample row = 10/6/2010,73.42,74.43,72.9,74.15,2993500""" filename_in = 'c:/python27/scripts/fiverows.csv' reader = csv.reader(open(filename_in, "rb"), dialect="excel", delimiter="\t", quoting =csv.QUOTE_MINIMAL) for row in reader: for item in row: print 'row = ',row print 'item = ', item When you run this script and print the row you get the sample row returned in [] as a list. When you print the item you get the sample row as an unquoted string. Why do I not get each field ie, (10/6/2010), (73.42), etc. returned as an item? How do I return a single item?

  • How do I make my browser brute force an input field?

    - by user210904
    Hi, There's a website I frequent that gives codes such as GD??Q-TPY32-TPTT3-9CM9P-F2QMQ and hints that the ?? is a number and a letter. If you're the first to unlock the code you can redeem the modest prize. So the obvious way to solve this problem is to brute-force the code. But obviously I don't want to sit in front of the computer for an hour to manually input all 10 * 26 combinations. Is there a way for me to tell my browser to input these codes (assume that each 5-character block is an individual text field). Or is there a special browser that enables some sort of macro-type feature? Thanks.

  • Redemption using filter on a custom datetime field in contacts.

    - by Spitje
    Hello, I'm having a problem using a filter on a custom date in contacts. RDOItems Contacts = null; string strSearch = string.Empty; strSearch = AddQuotes("http://schemas.microsoft.com/mapi/string/{01234567-8901-2345-C678-901234567801}/CustomFieldString"); strSearch += " <> '' "; strSearch += " AND "; strSearch += AddQuotes("http://schemas.microsoft.com/mapi/string/{01234567-8901-2345-C678-901234567802}/CustomFieldDate"); strSearch += " < "; strSearch += "'2010-04-28 18:00'"; Contacts = (RDOItems)synContacts.Items.Restrict(strSearch) When i use only the first part of the filter (CustomFieldString) i get the right contacts, but when i expand the filter with the datetime field no contacts are returned. Thanks, Spitje

  • What is the response on a REST call where a field is not valid?

    - by MediaSlayer
    There are many questions on StackOverflow about this, but no definitive answer. I have a REST resource where an entity's field, ProductId, is sent. If the ProductId passed is invalid, what kind of response would you do? I want to send the right response code plus information to the requester on what they can do to fix it. Initial thoughts were 422 with the body containing the list of errors in JSON/XML format. Maybe like this (JSON): [ { FieldName : "ProductId", ErrorCode : "M123", Description : "Product Not Found" }, { FieldName : "Quantity", ErrorCode : "Q001", Description : "Quantity cannot be more than 100" } ] Thoughts?

    I have a Profile model with a hasOne relationship to a Detail model. I have a registration form that saves data into both model's tables, but I want the username field from the profile model to be copied over to the usernamefield in the details model so that each has the same username. function new_account() { if(!empty($this->data)) { $this->Profile->modified = date("Y-m-d H:i:s"); if($this->Profile->save($this->data)) { $this->data['Detail']['profile_id'] = $this->Profile->id; $this->data['Detail']['username'] = $this->Profile->username; $this->Profile->Detail->save($this->data); $this->Session->setFlash('Your registration was successful.'); $this->redirect(array('action'=>'index')); } } } This code in my Profile controller gives me the error: Undefined property: Profile::$username Any ideas?

  • jQuery: What listener do I use to check for browser auto filling the password input field?

    - by Jannis
    Hi, I have a simple problem that I cannot seem to find a solution to. Basically on this website here: http://dev.supply.net.nz/vendorapp/ (currently in development) I have some fancy label animations sliding things in and out on focus & blur. However once the user has logged in once the browser will most likely remember the password associated with the users email address/login. (Which is good and should not be disabled.) However I run into issues triggering my label slide out animation when the browser sets the value on the #password field automatically as the event for this is neither focus nor blur. Does anyone know which listener to use to run my function when the browser 'auto fills' the users password? Here is a quick screenshot of the issue:

  • How to style just one type of input field without also affecting other input types with CSS

    - by James
    Is there a way to write style rules that will only influence text fields. Suppose I have the following: <div id="helloDiv"> <input type="text" name="something" /><br /> <input type="checkbox" name="somethingElse" /><br /> <input type="submit" name="go" /> </div> div#helloDiv input { border: 1px solid red; } The problem with the above CSS rule is that it will affect ALL input fields not just input text but also radio buttons, submit buttons, etc. So is there a cross browser solution to affect just one type of input field within a div or other page element (without resorting to assigning the input fields styles individually).

  • Specifying default value for django hidden form field - bone DRY?

    - by jMyles
    So let's say at the last minute (in the view) I decide I want to specify a default for a field and make it hidden, like so: form.fields['coconut'] = forms.ModelChoiceField(label="", widget=forms.HiddenInput(), queryset=swallow.coconuts.all(), initial=some_particular_coconut) My question is this: Do I really need to specify queryset here? I mean, I already know, from initial, exactly which coconut I'm talking about. Why do I also need to specify that the universe of available coconuts is the set of coconuts which this particular swallow carried (by the husk)? Is there a way I can refrain from specifying queryset? Simply omitting causes django to raise TypeError. If indeed it is required, isn't this a bit damp?

  • What is a good solution to link different tables in Hibernate based on some field value?

    - by serg555
    I have article table and several user tables a_user, b_user, ... with exactly the same structure (but different data). I can't change anything in *_user tables except their table name prefix but can change everything else (user tables contain only user information, there is nothing about article or user_type in them). I need to link article to a user (many-to-one), but user table name is defined by user_type field. For example Article table record: ... user_id="5" user_type="a" means that it is linked to a user with id=5 from a_user table (id 5 is not unique in users scope, each user table can have its id 5). Any suggestions how to handle this situation? How can I map this relation in Hibernate (xml mapping, no annotations) so it will automatically pick up correct user for an article during select/update? How should I map user tables (one or multiple classes?)? I would need to run some queries like this: from Article a where a.userType=:type and a.user.name=:name Thanks.

  • HTML/Javascript: Is it possible to remember the filename from a fileupload field ONLY and then later

    - by Pieter Breed
    I have a HTML file upload field from which I'm reading the file name of the file that the user specifies. The actual contents of the file is never uploaded. At a later stage, is it possible to construct a link using this file name information so that if the user clicks on this link, the original file is launched into a new browser window? If not, what are the reason for disallowing this behaviour? The purpose of such a feature is to store links to documents that are available on a mapped local drive or a network share.

  • Shortcut to get all private field names combined with && operator as a generated line of code?

    - by burak ozdogan
    Hi, Is it possible to use reflection when we write a code-template? I was just thinking if it is possible to write a piece of code-template that will return me a list of all private field in the class separated by && operator in Visual Stuudio? Let's say, I will enter "getAllPrivates&&" (or press a shortcut key) in the VS editor and it will return me something like this: private bool _privateFiel1 = false; private bool _privateFiel2 = true; private bool _privateFiel3 = false; private bool _privateFiel4 = false; private bool _privateFiel5 = true; // Here I press the shortcut or call the code-template and get his: _privateFiel1 && _privateFiel2 && _privateFiel3 && _privateFiel4 && _privateFiel5

  • django - where to clean extra whitespace from form field inputs?

    - by Westerley
    I've just discovered that Django doesn't automatically strip out extra whitespace from form field inputs, and I think I understand the rationale ('frameworks shouldn't be altering user input'). I think I know how to remove the excess whitespace using python's re: #data = re.sub('\A\s+|\s+\Z', '', data) data = data.strip() data = re.sub('\s+', ' ', data) The question is where should I do this? Presumably this should happen in one of the form's clean stages, but which one? Ideally, I would like to clean all my fields of extra whitespace. If it should be done in the clean_field() method, that would mean I would have to have a lot of clean_field() methods that basically do the same thing, which seems like a lot of repetition. If not the form's cleaning stages, then perhaps in the model that the form is based on? Thanks for your help! W.
