  • Using "wildcards" in a vlist array to delete rows in Excel

    - by KMinner
    Good Morning All, I'm trying to setup a vba macro to delete all user IDs out of a spreadsheet that do not start with designated prefixes (e.g. US, A1, VM, etc). The below block of code was found on the Code Library and looks to be what I need but there is one problem: When I enter in UserID prefixes into the vlist fields, it treats them as absolute rather then a part of the string that I want to keep. Is there a way to incorporate wildcards into a vlist? Sub Example1() Dim vList Dim lLastRow As Long, lCounter As Long Dim rngToCheck As Range, rngFound As Range, rngToDelete As Range Application.ScreenUpdating = False With Sheet1 lLastRow = Get_Last_Row(.Cells) If lLastRow > 1 Then vList = Array("US", "A1", "EG", "VM") 'we don't want to delete our header row With .Range("A2:A" & lLastRow) For lCounter = LBound(vList) To UBound(vList) Set rngFound = .Find( _ what:=vList(lCounter), _ lookat:=xlWhole, _ searchorder:=xlByRows, _ searchdirection:=xlNext, _ MatchCase:=True) 'check if we found a value we want to keep If rngFound Is Nothing Then 'there are no cells to keep with this value If rngToDelete Is Nothing Then Set rngToDelete = .Cells Else 'if there are no cells with a different value then 'we will get an error On Error Resume Next If rngToDelete Is Nothing Then Set rngToDelete = .ColumnDifferences(Comparison:=rngFound) Else Set rngToDelete = Intersect(rngToDelete, .ColumnDifferences(Comparison:=rngFound)) End If On Error GoTo 0 End If Next lCounter End With If Not rngToDelete Is Nothing Then rngToDelete.EntireRow.Delete End If End With Application.ScreenUpdating = True End Sub

  • Android Cursor strange behaviour

    - by sandis
    After many houres of bug searching in a big app, I have finally tracked down the bug. This logging captures the problem: Log.d(TAG,"buildList, DBresult.getInt(1): "+DBresult.getInt(1)); Log.d(TAG,"buildList, DBresult.getString(1): "+DBresult.getString(1)); Log.d(TAG,"buildList, DBresult.getInt(4): "+DBresult.getInt(4)); Log.d(TAG,"buildList, DBresult.getString(4): "+DBresult.getString(4)); The resulting output: 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getInt(1): 0 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getString(1): false 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getInt(4): 0 05-06 11:11:20.123: DEBUG/TodoList(18943): buildList, DBresult.getString(4): true There are no backgroung threads running. As you can see the problem is that '0' is interpreted as false on one occasion, and as true on another. Since I am completely lost on how this can happen, I dont know how to proceed. What could possibly result in such a behaviour? Both the columns are of the type "boolean", i.e a numeric in sqlite. Unfortunately the string returned is the correct value, while the integer is always 0. If I export the database to my computer and check it with SQlite Administrator I can see that the values are correctly set, it is only the getInt()-function that always returns 0. I know for a fact that this works in other apps I have coded, and I dont know why this has stopped working. I have tried compiling the code under 2.0, 2.0.1 and 2.1, and it always appears. I can make my app runnable again by getting boolean values like this: myBool= (DBresult.getString(0).equals("true")); but that is both ugly and not optimized. Any suggestions on what is causing this behaviour is welcome. Cheers,

  • Radiobutton in iphone

    - by Harita
    hi, i am using radio button image (empty circle) in button to answer the question from 3 options, and the 3 options are radio button's. i have created 3 uibuttons programmatically in tableview delegate method cellforrowatindexpath. i need when one button is selected(with filled circle image) other one if selected before gets unselected. i am using below code in button clicked method. static int _row; -(IBAction) optionClicked:(id)sender { UIButton *btn = (UIButton)sender; _row = btn.tag; if (btn.tag == 0) { if(btn1On) { [btnrad1 setImage:[UIImage imageNamed:@"unfilled.png"]forState:UIControlStateNormal]; btn1On=FALSE; } else { [btnrad1 setImage:[UIImage imageNamed:@"filled.png"]forState:UIControlStateNormal]; btn1On = TRUE; btn2On = FALSE; btn3On = FALSE; } } else if (btn.tag == 1) { if(btn2On) { [btnrad2 setImage:[UIImage imageNamed:@"unfilled.png"]forState:UIControlStateNormal]; btn2On=FALSE; } else { [btnrad2 setImage:[UIImage imageNamed:@"filled.png"]forState:UIControlStateNormal]; btn2On = TRUE; btn1On = FALSE; btn3On = FALSE; } } else if (btn.tag == 2) { if(btn3On) { [btnrad3 setImage:[UIImage imageNamed:@"unfilled.png"]forState:UIControlStateNormal]; btn3On=FALSE; } else { [btnrad3 setImage:[UIImage imageNamed:@"filled.png"]forState:UIControlStateNormal]; btn3On = TRUE; btn1On = FALSE; btn2On = FALSE; } } else { NSLog(@"Error"); } } above code is doing selection of button in another row. like i am selecting 1st option in 1st row but its is selecting 2nd row button. i don't know how to use _row to check for every cell of table view.

  • Accept templated parameter of stl_container_type<string>::iterator

    - by Rodion Ingles
    I have a function where I have a container which holds strings (eg vector<string>, set<string>, list<string>) and, given a start iterator and an end iterator, go through the iterator range processing the strings. Currently the function is declared like this: template< typename ContainerIter> void ProcessStrings(ContainerIter begin, ContainerIter end); Now this will accept any type which conforms to the implicit interface of implementing operator*, prefix operator++ and whatever other calls are in the function body. What I really want to do is have a definition like the one below which explicitly restricts the amount of input (pseudocode warning): template< typename Container<string>::iterator> void ProcessStrings(Container<string>::iterator begin, Container<string>::iterator end); so that I can use it as such: vector<string> str_vec; list<string> str_list; set<SomeOtherClass> so_set; ProcessStrings(str_vec.begin(), str_vec.end()); // OK ProcessStrings(str_list.begin(), str_list.end()); //OK ProcessStrings(so_set.begin(), so_set.end()); // Error Essentially, what I am trying to do is restrict the function specification to make it obvious to a user of the function what it accepts and if the code fails to compile they get a message that they are using the wrong parameter types rather than something in the function body that XXX function could not be found for XXX class.

  • How to perform Rails model validation checks within model but outside of filters using ledermann-rails-settings and extensions

    - by user1277160
    Background I'm using ledermann-rails-settings (https://github.com/ledermann/rails-settings) on a Rails 2/3 project to extend virtually the model with certain attributes that don't necessarily need to be placed into the DB in a wide table and it's working out swimmingly for our needs. An additional reason I chose this Gem is because of the post How to create a form for the rails-settings plugin which ties ledermann-rails-settings more closely to the model for the purpose of clean form_for usage for administrator GUI support. It's a perfect solution for addressing form_for support although... Something that I'm running into now though is properly validating the dynamic getters/setters before being passed to the ledermann-rails-settings module. At the moment they are saved immediately, regardless if the model validation has actually fired - I can see through script/console that validation errors are being raised. Example For instance I would like to validate that the attribute :foo is within the range of 0..100 for decimal usage (or even a regex). I've found that with the previous post that I can use standard Rails validators (surprise, surprise) but I want to halt on actually saving any values until those are addressed - ensure that the user of the GUI has given 61.43 as a numerical value. The following code has been borrowed from the quoted post. class User < ActiveRecord::Base has_settings validates_inclusion_of :foo, :in => 0..100 def self.settings_attr_accessor(*args) >>SOME SORT OF UNLESS MODEL.VALID? CHECK HERE args.each do |method_name| eval " def #{method_name} self.settings.send(:#{method_name}) end def #{method_name}=(value) self.settings.send(:#{method_name}=, value) end " end >>END UNLESS end settings_attr_accessor :foo end Anyone have any thoughts here on pulling the state of the model at this point outside of having to put this into a before filter? The goal here is to be able to use the standard validations and avoid rolling custom validation checks for each new settings_attr_accessor that is added. Thanks!

  • How to close all tabs in Safari using AppleScript?

    - by Form
    I have made a very simple AppleScript to close all tabs in Safari. The problem is, it works, but not completely. Here's the code: tell application "Safari" repeat with aWindow in windows repeat with aTab in tabs of aWindow aTab close end repeat end repeat end tell I've also tried this script: tell application "Safari" repeat with i from 0 to the number of items in windows set aWindow to item i of windows repeat with j from 0 to the number of tabs in aWindow set aTab to item j of tabs of aWindow aTab close end repeat end repeat end tell ... but it does not work either. I tried that on my system (MacBook Pro jan 2008), as well as on a Mac Pro G5 under Tiger and the script fails on both, albeit with a much less descriptive error on Tiger. The problem is that only a couple of tabs are closed. Running the script a few times closes a few tab each time until none is left, but always fails with the same error after closing a few tabs. Under Leopard I get an out of bounds error. Since I am using fast enumeration (not using "repeat from 0 to number of items in windows") I don't see how I can get an out of bounds error with this... My goal is to use the Cocoa Scripting Bridge to close tabs in Safari from my Objective-C Cocoa application but the Scripting Bridge fails in the same manner. The non-deletable tabs show as NULL in the Xcode debugger, while the other tabs are valid objects from which I can get values back (such as their title). In fact I tried with the Scripting Bridge first then told myself why not try this directly in AppleScript and I was surprised to see the same results. I must have a glaring omission or something in there... (seems like a bug in Safari AppleScript support to me... :S) I've used repeat loops and Obj-C 2.0 fast enumeration to iterate through collections before with zero problems, so I really don't see what's wrong here. Anyone can help? Thanks in advance!

  • git-diff to ignore ^M

    In a project where some of the files contains ^M as newline separators. Diffing these files are apparently impossible, since git-diff sees it as the entire file is just a single line.

  • How do I add code automatically to a derived function in C++

    - by Ian
    I have code that's meant to manage operations on both a networked client and a server, since there is significant overlap between the two. However, there are a few functions here and there that are meant to be exclusively called by the client or server, and accidentally calling a client function on the server (or vice versa) is a significant source of bugs. To reduce these sorts of programming errors, I'm trying to tag functions so that they'll raise a ruckus if they're misused. My current solution is a simple macro at the start of each function that calls an assert if the client or server accesses members they shouldn't. However, this runs into problems when there are multiple derived instances of classes, in that I have to tag the implementation as client or server side in EVERY child class. What I'd like to be able to do is put a tag in the virtual member's signature in the base class, so that I only have to tag it once and not run into errors by forgetting to do it repeatedly. I've considered putting a check in a base class implementation and then referring to it with something like base::functionName, but that runs into the same issue as far as needing to manually add the function call to every implementation. Ideally, I'd be able to have parent versions of the function called automatically like default constructors do. Does anybody know how to achieve something like this in C++? Is there an alternate approach I should be considering? Thanks!

  • How to partition bits in a bit array with less than linear time

    - by SiLent SoNG
    This is an interview question I faced recently. Given an array of 1 and 0, find a way to partition the bits in place so that 0's are grouped together, and 1's are grouped together. It does not matter whether 1's are ahead of 0's or 0's are ahead of 1's. An example input is 101010101, and output is either 111110000 or 000011111. Solve the problem in less than linear time. Make the problem simpler. The input is an integer array, with each element either 1 or 0. Output is the same integer array with integers partitioned well. To me, this is an easy question if it can be solved in O(N). My approach is to use two pointers, starting from both ends of the array. Increases and decreases each pointer; if it does not point to the correct integer, swap the two. int * start = array; int * end = array + length - 1; while (start < end) { // Assume 0 always at the end if (*end == 0) { --end; continue; } // Assume 1 always at the beginning if (*start == 1) { ++start; continue; } swap(*start, *end); } However, the interview insists there is a sub-linear solution. This makes me thinking hard but still not get an answer. Can anyone help on this interview question?

  • Ways to implement tags - pros and cons of each

    - by bobobobo
    Related Using SO as an example, what is the most sensible way to manage tags if you anticipate they will change often? Way 1: Seriously denormalized (comma delimited) table posts +--------+-----------------+ | postId | tags | +--------+-----------------+ | 1 | c++,search,code | Here tags are comma delimited. Pros: Tags are retrieved at once with a single select query. Updating tags is simple. Easy and cheap to update. Cons: Extra parsing on tag retrieval, difficult to count how many posts use which tags. (alternatively, if limited to something like 5 tags) table posts +--------+-------+-------+-------+-------+-------+ | postId | tag_1 | tag_2 | tag_3 | tag_4 | tag_5 | +--------+-------+-------+-------+-------+-------+ | 1 | c++ |search | code | | | Way 2: "Slightly normalized" (separate table, no intersection) table posts +--------+-------------------+ | postId | title | +--------+-------------------+ | 1 | How do u tag? | table taggings +--------+---------+ | postId | tagName | +--------+---------+ | 1 | C++ | | 1 | search | Pros: Easy to see tag counts (count(*) from taggings where tagName='C++'). Cons: tagName will likely be repeated many, many times. Way 3: The cool kid's (normalized with intersection table) table posts +--------+---------------------------------------+ | postId | title | +--------+---------------------------------------+ | 1 | Why is a raven like a writing desk? | table tags +--------+---------+ | tagId | tagName | +--------+---------+ | 1 | C++ | | 2 | search | | 3 | foofle | table taggings +--------+---------+ | postId | tagId | +--------+---------+ | 1 | 1 | | 1 | 2 | | 1 | 3 | Pros: No repeating tag names. More girls will like you. Cons: More expensive to change tags than way #1.

  • Incorrect component when querying immediately after insert using NHibernate

    - by Am
    I have the following mapping for my table in MySql: <class name="Tag, namespace" table="tags" > <id name="id" type="Int32" unsaved-value="0"> <generator class="native"></generator> </id> <property name="name" type="String" not-null="true"></property> <component name="record_dates" class="DateMetaData, namespace" > <property name="created_at" type="DateTime" not-null="true"></property> <property name="updated_at" type="DateTime" not-null="true"></property> </component> </class> As you see the record_dates property is defined as a component field of type DateMetaDate. Both created_at and updated_at fields in 'tags' table are updated via triggers. Thus I can insert a new record like such: var newTag = new Tag() { name = "some string here" } Int32 id = (Int32)Session.Save(tag); Session.Flush(); ITag t = Session.Get<Tag>(id); ViewData["xxx"] = t.name; // -----> not null ViewData["xxx"] = t.record_dates.created_at; // -----> is null However when querying the same record back immediately after it was inserted the record_dates field ends up null even though in the table those fields have got values. Can any one please point out why the Session.Get ignores getting everything back from the table? is it because it caches the newly created record for which the records_dates is null? If so how can it be told to ignore the cached version?

Hate having a sql statement in the middle of everthing. Note: There is paging involved and I would prefer not returning all the data to the app server before cutting it down.

  • routes as explained in RoR tutorial 2nd Ed?

    - by 7stud
    The author, Michael Hartl, says: Here the rule: get "static_pages/home" maps requests for the URI /static_pages/home to the home action in the StaticPages controller. How? The type of request is given, the url is given, but where is the mapping to a controller and action? My tests all pass, though. I also tried deleting all the actions in the StaticPagesController, which just looks like this: class StaticPagesController < ApplicationController def home end def about end def help end def contact end end ...and my tests still pass, which is puzzling. The 2nd edition of the book(online) is really frustrating. Specifically, the section about making changes to the Guardfile is impossible to follow. For instance, if I instruct you to edit this file: blah blah blah dog dog dog beetle beetle beetle jump jump jump and make these changes: blah blah blah . . . go go go . . . jump jump jump ...would you have any idea where the line 'go go go' should be in the code? And the hint for exercise 3.5-1 is flat out wrong. If the author would put up a comment section at the end of every chapter, the rails community could self-edit the book.

Here is the code I have so far: FUNCTION calcTargetTotal(accountId varchar2, newTotal numeric ) RETURN number is oldTotal numeric(20,6); difference numeric(20,6); begin difference := 0; begin select value into oldTotal from target_total WHERE account_id = accountId for update of value; if (oldTotal != newTotal) then update target_total set value = newTotal WHERE account_id = accountId difference := newTotal - oldTotal; end if; exception when NO_DATA_FOUND then begin difference := newTotal; insert into target_total ( account_id, value ) values ( accountId, newTotal ); -- sometimes a race condition occurs and this stmt fails -- in those cases try to update again exception when DUP_VAL_ON_INDEX then begin difference := 0; select value into oldTotal from target_total WHERE account_id = accountId for update of value; if (oldTotal != newTotal) then update target_total set value = newTotal WHERE account_id = accountId difference := newTotal - oldTotal; end if; end; end; end; return difference end calcTargetTotal; This works as expected in unit tests with multiple threads never failing. However when loaded on a live system we have seen this fail with a stack trace looking like this: ORA-01403: no data found ORA-00001: unique constraint () violated ORA-01403: no data found The line numbers (which I have removed since they are meaningless out of context) verify that the first update fails due to no data, the insert fail due to uniqueness, and the 2nd update is failing with no data, which should be impossible. From what I have read on other thread a MERGE statement is also not atomic and could suffer similar problems. Does anyone have any ideas how to prevent this from occurring?

  • Ruby on Rails: How to create associated models on the fly ?

    - by Misha Moroshko
    I have the following models: class Product < ActiveRecord::Base belongs_to :brand belongs_to :model accepts_nested_attributes_for :brand, :model ... end class Brand < ActiveRecord::Base has_many :products has_many :models ... end class Model < ActiveRecord::Base has_many :products belongs_to :brand accepts_nested_attributes_for :brand ... end I have a problem to create a new product. Here is the relevant code in the controller: class ProductsController < ApplicationController ... def create @product = Product.new(params[:product]) if @product.save ... # Here is the error end ... end When user adds a new brand and a new model, params[:product] contains the following: "brand_attributes"=>{"name"=>"my_new_brand"} "model_attributes"=>{"model_no"=>"my_new_model"} and I got the following error: Mysql2::Error: Column 'brand_id' cannot be null: INSERT INTO `models` ... because model has a foreign key brand_id which is not set. I can't set it because the brand (like the model) is created on the fly when the product is created. I don't want to create the brand before the product, because then I the product has errors, I will need to delete the created brand. Then I tried to change params[:product] like this: "brand_attributes"=>{"name"=>"my_new_brand", "model_attributes"=>{"model_no"=>"my_new_model"}} but I end up with this: unknown attribute: model_attributes What would be the proper way to handle this ?

  • Rails partial gets double escaped when using link_to_function

    - by dombesz
    Hi, I have the following code. def add_resume_link(name, form) link_to_function name do |page| html = form.fields_for :resumes, @general_resume.resumes.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial => 'resume_form', :locals=>{:form=>form_parent} end page << "$('resumes').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, id) });" end end And on the resume_form i have somewhere: =add_skill_link("Add Skill", form, "resume_#{id}_skills") and the function looks like: def add_skill_link(name, form, id) link_to_function name do |page| html = form.fields_for :skill_items, @general_resume.skill_items.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial=>'skill_form', :locals=>{:form=>form_parent, :parent=>id} end page << "$('#{id}').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, new Date().getTime()) });" end end So basically i have a javascript code which dinamically adds a piece of html (add_resume) and contains another javascript code which dinamically adds a select box to the page. My problem is that the add_skill_link works fine if i use from the server side, i mean rendering from server side. And gets double escaped when using within the upper described way. I tried to remove the escape_javascript from the add_skill_link bit still not good. Any ideas?

  • Modules vs. Classes and their influence on descendants of ActiveRecord::Base

    - by Chris
    Here's a Ruby OO head scratcher for ya, brought about by this Rails scenario: class Product < ActiveRecord::Base has_many(:prices) # define private helper methods end module PrintProduct attr_accessor(:isbn) # override methods in ActiveRecord::Base end class Book < Product include PrintProduct end Product is the base class of all products. Books are kept in the products table via STI. The PrintProduct module brings some common behavior and state to descendants of Product. Book is used inside fields_for blocks in views. This works for me, but I found some odd behavior: After form submission, inside my controller, if I call a method on a book that is defined in PrintProduct, and that method calls a helper method defined in Product, which in turn calls the prices method defined by has_many, I'll get an error complaining that Book#prices is not found. Why is that? Book is a direct descendant of Product! More interesting is the following.. As I developed this hierarchy PrintProduct started to become more of an abstract ActiveRecord::Base, so I thought it prudent to redefine everything as such: class Product < ActiveRecord::Base end class PrintProduct < Product end class Book < PrintProduct end All method definitions, etc. are the same. In this case, however, my web form won't load because the attributes defined by attr_accessor (which are "virtual attributes" referenced by the form but not persisted in the DB) aren't found. I'll get an error saying that there is no method Book#isbn. Why is that?? I can't see a reason why the attr_accessor attributes are not found inside my form's fields_for block when PrintProduct is a class, but they are found when PrintProduct is a Module. Any insight would be appreciated. I'm dying to know why these errors are occurring!

  • Ruby on Rails controller and architecture with cells

    - by dt
    I decided to try to use the cells plugin from rails: http://cells.rubyforge.org/community.html given that I'm new to Ruby and very used to thinking in terms of components. Since I'm developing the app piecemeal and then putting it together piece by piece, it makes sense to think in terms of components. So, I've been able to get cells working properly inside a single view, which calls a partial. Now, what I would like to be able to do (however, maybe my instincts need to be redirected to be more "Rails-y"), is call a single cell controller and use the parameters to render one output vs. another. Basically, if there were a controller like: def index params[:responsetype] end def processListResponse end def processSearchResponse end And I have two different controller methods that I want to respond to based on the params response type, where I have a single template on the front end and want the inner "component" to render differently depending on what type of request is made. That allows me to reuse the same front-end code. I suppose I could do this with an ajax call instead and just have it rerender the component on the front end, but it would be nice to have the option to do it either way and to understand how to architect Rails a bit better in the process. It seems like there should be a "render" option from within the cells framework to render to a certain controller or view, but it's not working like I expect and I don't know if I'm even in the ballpark. Thanks!

  • form:select items problem in spring mvc portlet

    - by dhaval
    I have a set of drop-down control which I want to render with my custom tag library. The following is the code of the tag lib: <spring:bind path="${path}"> <c:choose> <c:when test="${readOnly}"> <span class="readOnly">${status.value}</span> </c:when> <c:otherwise> <form:select path="${path }" itemLabel="${label }" itemValue="${value }" items="${itemList}"> </form:select> </c:otherwise> </c:choose> And this is the code I have written in the JSP file: <tag:conditionalListControl path="model.selectedCountry" readOnly="false" label="name" value="id" listItems="model.countryList" className="simple" /> Upon execution the paring returns the following error: [jsp:165] javax.servlet.jsp.JspException: Type [java.lang.String] is not valid for option items But if i change the items="${itemList}" to items="${model.countryList}" which is the list I want to display, it works fine without any problem and also bind to required variables on form submit. But i don't want to hard code any variables in the tag lib. Any suggestions???
