  • Dynamically Populate Listbox - Exclude Empty cells

    - by Daniel
    I am creating a form in excel (not a userform) and I am populating the listbox using cells. However, these cells are sometimes A1:10 and sometimes they are A1:A4. Is there a way to dynamically change what is shown in the listbox? Right now, when I use A1:10 and there are only 4 cells populated, I get the list of 4 populated cells followed by 6 blank entries. I'd like to get rid of the 6 blanks when there are only 4.

  • How do I use udev to find info about inserted video media (e.g. DVDs)

    - by Daniel
    I'm trying to port an application from using HAL to using pure udev. It is written in python and will use the gudev library, though I would love to see examples in any language. I'm able to get all attached video devices (such as cameras) via: import gudev client = gudev.Client(["video4linux"]) for device in client.get_devices(): print device.get_sysfs_attr("name"), device.get_device_name() This prints out something like: USB2.0 UVC WebCam /dev/video0 I am also able to get a list of block devices, but how can I: Tell if it is a CD/DVD drive? Tell if media is currently inserted if the drive supports removable media? Tell what the name/label of the media is (e.g. FUTURAMAS1 for a DVD)? The original code I am trying to port over is located at http://github.com/danielgtaylor/arista/blob/045a4d48ebfda44bc5d0609618ff795604ee134f/arista/inputs.py Any and all help would be greatly appreciated!

  • How can I automatically refactor my classes to use the default namespace for the folder they're in?

    - by Daniel Schaffer
    I've been playing around with the structure of my project, and I'd like to reset the namespaces of my classes to what the default would be. That is, the default namespace for the project, plus each of the folders in the hierarchy. It's not as simple as just find + replace, since I've both added and renamed some folders, and files from some namespaces were split into multiple other namespaces. I'm using VS 2010.

  • Restrict sprite movement to vertical and horizontal

    - by Daniel Granger
    I have been battling with this for some time and my noob brain can't quite work it out. I have a standard tile map and currently use the following code to move my enemy sprite around the map -(void) movePlayer:(ccTime)deltaTime { if (CGPointEqualToPoint(self.position, requestedPosition)) return; float step = kPlayerSpeed * deltaTime; float dist = ccpDistance(self.position, requestedPosition); CGPoint vectorBetweenAB = ccpSub(self.position, requestedPosition); if (dist <= step) { self.position = requestedPosition; [self popPosition]; } else { CGPoint normVectorBetweenAB = ccpNormalize(vectorBetweenAB); CGPoint movementVectorForThisFrame = ccpMult(normVectorBetweenAB, step); if (abs(vectorBetweenAB.x) > abs(vectorBetweenAB.y)) { if (vectorBetweenAB.x > 0) { [self runAnimation:walkLeft]; } else { [self runAnimation:walkRight]; } } else { if (vectorBetweenAB.y > 0) { [self runAnimation:walkDown]; } else { [self runAnimation:walkUp]; } } if (self.position.x > movementVectorForThisFrame.x) { movementVectorForThisFrame.x = -movementVectorForThisFrame.x; } if (self.position.y > movementVectorForThisFrame.y) { movementVectorForThisFrame.y = -movementVectorForThisFrame.y; } self.position = ccpAdd(self.position, movementVectorForThisFrame); } } movePlayer: is called by the classes updateWithDeltaTime: method. the ivar requestedPosition is set in the updateWithDeltaTime method as well, it basically gets the next point out of a queue to move to. These points can be anywhere on the map, so if they are in a diagonal direction from the enemy the enemy sprite will move directly to that point. But how do I change the above code to restrict the movement to vertical and horizontal movement only so that the enemies movement 'staircases' its way along a diagonal path, taking the manhattan distance (I think its called). As shown by my crude drawing below... S being the start point F being the finish and the numbers being each intermediate point along its path to create a staircase type diagonal movement. Finally I intend to be able to toggle this behaviour on and off, so that I can choose whether or not I want the enemy to move free around the map or be restricted to this horizontal / vertical movement only. | | | | | | | | | | | | | | | | | | | | | |F| | | | | | | | | |5|4| | | | | | | | | |3|2| | | | | | | | | |1|S| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

  • Limit output of all Linux commands

    - by daniel
    I'm looking for a way to limit the amount of output produced by all command line programs in Linux, and preferably tell me when it is limited. I'm working over a server which has a lag on the display. Occasionally I will accidentally run a command which outputs a large amount of text to the terminal, such as cat on a large file or ls on a directory with many files. I then have to wait a while for all the output to be printed to the terminal. So is there a way to automatically pipe all output into a command like head or wc to prevent too much output having to be printed to terminal?

  • How do I create a self referential association (self join) in a single class using ActiveRecord in Rails?

    - by Daniel Chang
    I am trying to create a self join table that represents a list of customers who can refer each other (perhaps to a product or a program). I am trying to limit my model to just one class, "Customer". The schema is: create_table "customers", force: true do |t| t.string "name" t.integer "referring_customer_id" t.datetime "created_at" t.datetime "updated_at" end add_index "customers", ["referring_customer_id"], name: "index_customers_on_referring_customer_id" My model is: class Customer < ActiveRecord::Base has_many :referrals, class_name: "Customer", foreign_key: "referring_customer_id", conditions: {:referring_customer_id => :id} belongs_to :referring_customer, class_name: "Customer", foreign_key: "referring_customer_id" end I have no problem accessing a customer's referring_customer: @customer.referring_customer.name ... returns the name of the customer that referred @customer. However, I keep getting an empty array when accessing referrals: @customer.referrals ... returns []. I ran binding.pry to see what SQL was being run, given a customer who has a "referer" and should have several referrals. This is the SQL being executed. Customer Load (0.3ms) SELECT "customers".* FROM "customers" WHERE "customers"."id" = ? ORDER BY "customers"."id" ASC LIMIT 1 [["id", 2]] Customer Exists (0.2ms) SELECT 1 AS one FROM "customers" WHERE "customers"."referring_customer_id" = ? AND "customers"."referring_customer_id" = 'id' LIMIT 1 [["referring_customer_id", 3]] I'm a bit lost and am unsure where my problem lies. I don't think my query is correct -- @customer.referrals should return an array of all the referrals, which are the customers who have @customer.id as their referring_customer_id.

  • How does ruby allow a method and a Class with the same name?

    - by Daniel Beardsley
    I happened to be working on a Singleton class in ruby and just remembered the way it works in factory_girl. They worked it out so you can use both the long way Factory.create(...) and the short way Factory(...) I thought about it and was curious to see how they made the class Factory also behave like a method. They simply used Factory twice like so: def Factory (args) ... end class Factory ... end My Question is: How does ruby accomplish this? and Is there danger in using this seemingly quirky pattern?

  • Create Macro With Several Variables

    - by Daniel
    I have several worksheets with similar code, so I'd like to turn it into a macro. My only problem is that there are several variables. So at certain points the code looks like this: Dim Msg_1 As String Dim Msg_2 As String Public Sub ListBox1_LostFocus() ListBox1.Height = 15 With ListBox1 Msg1 = "'" For i = 0 To .ListCount - 1 If .Selected(i) Then Msg1 = Msg1 & .List(i) & "','" End If Next i End With Msg1 = Left(Msg1, Len(Msg1) - 2) Sheets("Sheet1").Range("R3", "R3") = Msg1 End Sub and so on. How can I pass in a new value for Msg1, Msg2, Msg3 for each worksheet?

  • How to return a string from char[] array using recursion loop.(java)

    - by Daniel
    I am very bed in recursion... I need to convert a char[] array by using recursion loop only, into string. Without using for(),while()... loops. For example if i have char array: a[0]='H', a[1]='e', a[2]='l',a[3]= 'l',a[4]= 'o', it returns H e l l o. What I doing wrong? public String toFormattedString(char[] a) { int temp =a.length; if (a == null) return "null"; if (a.length == 0) return "0"; if( a.length == 1 ) else if( a[0] == a[a.length] ) return toFormattedString (a[a.length -1])+a[a.length];

  • Should I focus on java or on C#

    - by Daniel
    My friend started his computer engineering studies this semester, and wants to know if he should focus on Java or C#? While I am more on the Java side of life, I don't know what to answer him unbiased, so If you can give some unbiased statements on this, this would be great.

  • Error reading file with accented vowels

    - by Daniel Dcs
    The following statement to fill a list from a file : action = [] with open (os.getcwd() + "/files/" + "actions.txt") as temp:          action = list (temp) gives me the following error: (result, consumed) = self._buffer_decode (data, self.errors, end) UnicodeDecodeError: 'utf-8' codec can not decode byte 0xf1 in position 67: invalid continuation byte if I add errors = 'ignore': action = [] with open (os.getcwd () + "/ files /" + "actions.txt", errors = 'ignore') as temp:          action = list (temp) Is read the file but not the ñ and vowels accented á-é-í-ó-ú being that python 3 works, as I have understood, default to 'utf-8' I'm looking for a solution for two or more days, and I'm getting more confused. In advance thank you very much for any suggestions.

  • Creating a good search solution

    - by Daniel
    I have an app where users have a role,a username,faculty and so on.When I'm looking for a list of users by their role or faculty or anything they have in common I can call (among others possible) @users = User.find_by_role(params[:role]) #or @users = User.find_by_shift(params[:shift]) So it keeps the system Class.find_by_property So the question is: What if at different points users lists should be generated based on different properties.I mean: I'm passing from different links params[:role] or params[:faculty] or params[:department] to my list action in my users controller.As I see it all has to be in that action,but which parameter should the search be made by?

  • 2014 Conferences - JFokus, JavaLand & GeeCon!

    - by Heather VanCura
    There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage.  We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs.   First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event.  I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR.  There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman.  This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development.  The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining,  I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015.  Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area.  Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities.  JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs.  Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference!  The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters.  We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms.  If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future.  Favorite take home gift - GeeCon mug!   These were some of the highlights of the events--looking forward to Devoxx UK next week.  I will publish these details tomorrow!

  • Aggregate survey results recursively by manager

    I have a StaffLookup table which looks like this.

UserSrn | QuestionId | ResponseScore ==================================== ABC2 | 1 | 5 ABC2 | 3 | 4 ABC4 | 16 | 3 ... What I am trying to do sounds pretty simple but I am struggling to find a neat, quick way of doing it. I want to create a sproc that takes an Srn and returns back all the staff under that Srn in the structure. If there is a score for QuestionId of 16 then that indicates a completed survey. I would like to return a line for the Srn entered (The top manager) with a count of completed surveys for the direct reports under that manager. Under that I would like each manager under the original manager with a count of completed surveys for each of their direct reports and so on. I would like to see the data as such below when I set the top manager to be Joe (ABC2). UserName | Completed | Total ============================ Joe | 2 | 2 Paul | 1 | 2 David | 0 | 2 TOTAL | 3 | 6
