  • Designing a Chart that expands as more data is entered in Excel

    - by Matt Ridge
    I have a worksheet that pulls data from another, it is designed to only show late jobs, and it works perfectly. I have it where it is broken down into quarters, and it gathers all this data and does everything I want. Except this one last bit... I want to have it where it shows charts, if there is data in said area the chart would self populate, otherwise it would be blank. If more data is entered into the range expand the chart accordingly. Attached is a simplified workbook with what it does, and what I'd like to see it do. I don't even know if this is possible... I thought if I wrote a script to make it so that the data changes with each addition it may fix my problem, but I'm not sure if that is the best way in this situation. https://dl.dropbox.com/u/3327208/Excel/Charts.xlsx

  • R data frame select by global variable

    - by Matt
    I'm not sure how to do this without getting an error. Here is a simplified example of my problem. Say I have this data frame DF a b c d 1 2 3 4 2 3 4 5 3 4 5 6 Then I have a variable x <- min(c(1,2,3)) Now I want do do the following y <- DF[a == x] But when I try to refer to some variable like "x" I get an error because R is looking for a column "x" in my data frame. I get the "undefined columns selected" error How can I do what I am trying to do in R?

  • FLOT: How to make different colored points in same data series, connected by a line?

    - by Mega Matt
    Hi all, I think I may have stumbled onto a limitation of Flot, but I'm not sure. I'm trying to represent a single data series over time. The items' "State" is represented on the Y-Axis (there are 5 of them), and time is on the X-Axis (items can change states over time). I want the graph to have points and lines connecting those points for each data series. In addition to tracking an item's State over time, I'd also like to represent it's "Status" at any of the particular points. This I would like to do by changing the color of the points. What this means is a single item may have different Statuses at different times, meaning for a single data series I need a line that connects different points (dots) of different colors. The only thing I've seen so far is the ability to specify the color for all points in a given dataseries. Does anyone know if there's a way to specify colors individually? Thanks.

  • Selecting items from events, as evenly spaced as possible

    - by Matt Warren
    If I have an event that happens 15 times a second (numbered 1 - 15), but I only want to process it 3 times I can choose [1], [6] and [11],. It's important that the events I process are as evenly spaced as possible and take into account wrap-around, i.e. the events are continuous 13, 14, 15, 1, 2, 3 etc. If I want 4 items the best I can do is [1], [5], [9] & [13]. Is there a general algorithm that will calculate which events I need to process given the total number of events (total) and the number to process (processAmount).

  • Get local network interface addresses using only proc?

    - by Matt Joiner
    How can I obtain the (IPv4) addresses for all network interfaces using only proc? After some extensive investigation I've discovered the following: ifconfig makes use of SIOCGIFADDR, which requires open sockets and advance knowledge of all the interface names. It also isn't documented in any manual pages on Linux. proc contains /proc/net/dev, but this is a list of interface statistics. proc contains /proc/net/if_inet6, which is exactly what I need but for IPv6. Generally interfaces are easy to find in proc, but actual addresses are very rarely used except where explicitly part of some connection. There's a system call called getifaddrs, which is very much a "magical" function you'd expect to see in Windows. It's also implemented on BSD. However it's not very text-oriented, which makes it difficult to use from non-C languages.

  • mysqli and php requesting rows returned in object oriented scripting...

    - by Matt
    in object oriented php mysqli I am trying to request a username, and return if it matches a row, without actually returning any user data. How would I write this?...so far I have... $sql = "SELECT NULL FROM database WHERE usernick=?"; $stmt = $link->prepare($sql) $stmt->bind_param('s', $snr); $stmt->execute(); After this step I need to see if a row matched the query...but I have no idea how to write it, everyone here pretty much writes in mysql if I dont mention I want object oriented mysqli :S

  • SQL Grouping with multiple joins combining results incorrectly

    - by Matt
    Hi I'm having trouble with my query combining records when it shouldn't. I have two tables Authors and Publications, they are related by Publication ID in a many to many relationship. As each author can have many publications and each publication has many Authors. I want my query to return every publication for a set of authors and include the ID of each of the other authors that have contributed to the publication grouped into one field. (I am working with mySQL) I have tried to picture it graphically below Table: authors Table:publications AuthorID | PublicationID PublicationID | PublicationName 1 | 123 123 | A 1 | 456 456 | B 2 | 123 789 | C 2 | 789 3 | 123 3 | 456 I want my result set to be the following AuthorID | PublicationID | PublicationName | AllAuthors 1 | 123 | A | 1,2,3 1 | 456 | B | 1,3 2 | 123 | A | 1,2,3 2 | 789 | C | 2 3 | 123 | A | 1,2,3 3 | 456 | B | 1,3 This is my query Select Author1.AuthorID, Publications.PublicationID, Publications.PubName, GROUP_CONCAT(TRIM(Author2.AuthorID)ORDER BY Author2.AuthorID ASC)AS 'AuthorsAll' FROM Authors AS Author1 LEFT JOIN Authors AS Author2 ON Author1.PublicationID = Author2.PublicationID INNER JOIN Publications ON Author1.PublicationID = Publications.PublicationID WHERE Author1.AuthorID ="1" OR Author1.AuthorID ="2" OR Author1.AuthorID ="3" GROUP BY Author2.PublicationID But it returns the following instead AuthorID | PublicationID | PublicationName | AllAuthors 1 | 123 | A | 1,1,1,2,2,2,3,3,3 1 | 456 | B | 1,1,3,3 2 | 789 | C | 2 It does deliver the desired output when there is only one AuhorID in the where statement. I have not been able to figure it out, does anyone know where i'm going wrong?

  • Error HRESULT E_FAIL when creating Exchange mailbox (CDOEXM.IMailboxStore.CreateMailbox)

    - by Matt
    I am trying to automate the process of creating an Exchange Mailbox for AD users and am running into an issue. When calling the CreateMailbox method I am receiving the error "Error HRESULT E_FAIL has been returned from a call to a COM component". I have installed and referenced the Exchange Management Tools and am using impersonation for permissions. Here is the code: ActiveDs.IADsUser adUser = (ActiveDs.IADsUser)user.NativeObject; adUser.AccountDisabled = !Active; user.CommitChanges(); //Set Password user.Invoke("SetPassword", Password); user.CommitChanges(); //Create Mailbox IMailboxStore mailbox; mailbox = (IMailboxStore)adUser; mailbox.CreateMailbox("LDAP://CN=StandardUsers,CN=StandardUsers,CN=InformationStore,CN=xxxxx," + "CN=Servers,CN=First Administrative Group,CN=Administrative Groups," + "CN=xxxxx Main,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=xxxxx,DC=com"); user.CommitChanges();

  • ASPX page renders differently when reached on intranet vs. internet?

    - by MattSlay
    This is so odd to me.. I have IIS 5 running on XP and it's hosting a small ASP.Net app for our LAN that we can access by using the computer name, virtual directory, and page name (http://matt/smallapp/customers.aspx), but you can also hit that IIS server and page from the internet because I have a public IP that my firewall routes to the "Matt" computer (like http://213.202.3.88/smallapp/customers.aspx [just a made-up IP]). Don't worry, I have Windows domain authentication is in place to protect the app from anonymous users. So all the abovea parts works fine. But what's weird is that the Border of the divs on the page are rendered much thicker when you access the page from the intranet, versus the internet, (I'm using IE8) and also, some of the div layout (stretching and such) acts differently. Why would it render different in the same browser based on whether it was reached from the LAN vs. the internet? It does NOT do this in FireFox. So it must be just an IE8 thing. All the CSS for the divs is right in the HTML page, so I do not think it is a caching matter of a CSS file. Notice how the borders are different in these two images: Internet: http://twitpic.com/hxx91 . Lan: http://twitpic.com/hxxtv

  • Build Path issue with Java Android project when starting Eclipse

    - by Matt Smith
    I booted up eclipse to start on a project, and without typing in a word I already have several errors. package department.namespace; import android.app.Activity; import android.os.Bundle; public class DepartmentActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } At package department.namespace, it says: multiple marks at this line and the type java.lang.Object cannot be resolved. It is indirectly referenced from required .class files The import android.os cannot be resolved. Override cannot be resolved as a type The method OnCreate(Bundle) is undefined for the type Activity R. cannot be resolved as a variable. Since this JUST came up when I started Eclipse, how do I fix this?

  • Is there a way to give a subquery an alias in Oracle 11g SQL?

    - by Matt Pascoe
    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

  • Does the java JFC hash table use seperate chaining resolution? Can I traverse each list in the table

    - by Matt
    I have written a program to store a bunch of strings in a JFC hash table. There are defiantly collisions going on, but I don't really know how it is handling them. My ultimate goal is to print the number of occurrences of each string in the table, and traversing the bucket or list would work nicely. Or maybe counting the collisions? Or do you have another idea of how I could get a count of the elements?

  • ruby inject recursion?

    - by Matt Humphrey
    the goal is to start with ['a','b','c'] and end up with {'a'={'b'={'c'={}}}} so, getting my bearings, i did this: ruby-1.8.7-p174 ['a','b','c'].inject({}){|h,v| h.update(v = {})} = {"a"={}, "b"={}, "c"={}} and then figured, if i actually pass on the result hash, it will recurse and nest, but: ruby-1.8.7-p174 ['a','b','c'].inject({}){|h,v| h.update(v = {}); h[v]} = {} why is this? any idea how to achieve the desired result in an elegant one-liner?

  • Unit Testing Model Classes that inherits from NSManagedObject

    - by Matt Baker
    So...I'm trying to get unit tests set up in my iPhone App but I'm having some issues. I'm trying to test my model classes but they inherit directly from NSManagedObject. I'm sure this is a problem but I don't know how to get around it. Everything is building and running as expected but I get this error when calling any method on the class I'm testing: Unknown.m:0:0 unrecognized selector sent to instance 0xc2b120 If I follow this structure (http://chanson.livejournal.com/115621.html) to create my object in my tests I end up with another error entirely but it still doesn't help me. Basically my question is this: how can I test a class that inherits from NSManagedObject?

  • Wasteful Ajax Page Loading

    - by Matt Dawdy
    I've started a new job, and the portion of the project I'm working has a very odd structure. Every pages is a .Net aspx page, and it loads just fine, but nothing is really done at load time. Everything is really loaded from a jquery document.onready handler. What is even more...interesting...is that the onready handler calls some ajax calls that drop entire .aspx pages into divs on the page, but first it strips out several parts of the the returned page. This is the "magic" script the previous programmer ran on all the returned html from his ajax calls: function CleanupResponseText(responseText, uniqueName) { responseText = responseText.replace("theForm.submit();", "SubmitSubForm(theForm, $(theForm).parent());"); responseText = responseText.replace(new RegExp("theForm", "g"), uniqueName); responseText = responseText.replace(new RegExp("doPostBack", "g"), "doPostBack" + uniqueName); return responseText; } He then intercepts any kind of form postback and runs his own form submission function: function SubmitSubForm(form, container) { //ShowLoading(container); $(form).ajaxSubmit( { url: $(form).attr("action"), success: function(responseText) { $(container).html(CleanupResponseText(responseText, form.id)); $("form", container).css("margin-top", "0").css("padding-top", "0"); //HideLoading(container); } } ); } Am I way offbase in thinking that this is less than optimal? I mean, how does a browser take out the html and head and other tags that don't have anything to do with what you are really trying to drop into that div? Also, he's returning things like asp:gridview controls, and the associate viewstate, which can be quite large if his dataset is big. Has anyone seen this before?

  • Will iPhone OS4 make your life easier or harder as a lone app developer?

    - by Matt
    I am interested to hear what people feel about the new iPhone OS4 release. It is obviously very exciting having access to all the new features, apparently (from apple.com) it has over 1500 new APIs. My original thoughts were "Wow, this is awesome", and I suppose it is. I was just getting comfortable with OS 3.2 development though, and now there is a raft of additional stuff to learn in order to keep up with the pack. So I am feeling quite frustrated! Do you think, when working as an individual app developer, having access to these additional features would improve your applications or just water down the quality? I guess being giving the opportunity to improve applications and provide better features should be welcomed. I think frustration comes from struggling to keep up with the continuous changes, but thats the industry we are in I suppose! Any thoughts/comments?

  • Force Binding Update Silverlight

    - by Matt
    How can I force my objects DataContext bindings to update? I'm using an event on a grid, and binding updates are not being processed before my event fires. Any cheap tricks to get around this? In the end I can always do things the old manual way of getting the values from my textboxes and updating my object, but it'd be nice to have binding do it for me.

  • What IoC Containers Support Silverlight?

    - by Matt Casto
    I'm looking for a list of IoC Containers that support Silverlight. I know that Unity and Ninject work with Silverlight, but I haven't found any information that suggests that other well known containers, like StructureMap, Castle Windsor or Autofac, support Silverlight. Has anyone used these, or other, containers or compared them with the Silverlight platform in mind?
