  • NDepend query methods/types in framework assembly being used by other assemblies/types

    - by icelava
    I am trying to determine which types or methods in a base framework assembly are being used by other assemblies in the application system. I cannot seem to find a straight-cut query to do that. What i have to do is first determine which assemblies are directly using the framework assembly, then manually list them in a second query SELECT TYPES FROM ASSEMBLIES "IBM.Data.DB2" WHERE IsDirectlyUsedBy "ASSEMBLY:FirstDirectUsedByAssebmly" OR IsDirectlyUsedBy "ASSEMBLY:SecondDirectUsedByAssebmly" OR IsDirectlyUsedBy "ASSEMBLY:ThirdDirectUsedByAssebmly" OR IsDirectlyUsedBy "ASSEMBLY:FourthDirectUsedByAssebmly" Is there a better/faster way to query for this? Additionally, the query results are focused on the matched types only. The Dependency graph or matrix exported only shows details of those. I do not know how to render a graph that shows those types or methods plus show the dependent types/methods from other assemblies that are consuming them?

  • WPF Theming and dynamic controls

    - by Eduard
    Hello, I am trying to add control to ContentPresenter on then run, but control I've added does not apply theme. Theres is code with reference to theme in xaml file: <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Resources/PocGraphDataTemplates.xaml" /> </ResourceDictionary.MergedDictionaries> Also I've tried to set style in code behind, does not work: this.graphLayout.Content = analyzerViewModel.AnalyzedLayout = new PocGraphLayout() { LayoutAlgorithmType = "FR" }; ResourceDictionary rd = new ResourceDictionary(); rd.Source = new Uri("Resources/PocGraphDataTemplates.xaml", UriKind.Relative); analyzerViewModel.AnalyzedLayout.Style = new Style(typeof(PocGraphLayout)); analyzerViewModel.AnalyzedLayout.Style.Resources.MergedDictionaries.Add(rd); When control was static everything worked fine: <ViewModel:PocGraphLayout x:Name="graphLayout" Graph="{Binding Path=Graph}" LayoutAlgorithmType="{Binding Path=LayoutAlgorithmType}" Sample:LayoutManager.ManagedLayout="True" OverlapRemovalAlgorithmType="FSA" HighlightAlgorithmType="Simple" /> Any ideas? PS. I am newbie in wpf.

  • Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

    - by Luke Mcneice
    I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

  • iPhone - how to find a parent View

    - by Oscar Peli
    Hi there, I need some help to find a View inside a hierarchy. Here is how I build up the View stack. Inside my first UITableViewController I push an UIViewController that contains an UITabBarController: [[self navigationController] pushViewController:itemVC animated:YES]; Inside the UITabBarController I add an UITableViewController: ISSTableViewController *graphics = (ISSTableViewController *)[tabBarController.viewControllers objectAtIndex:3]; Inside the didSelectRowAtIndexPath I present a Modal View Controller using a UINavigationController: GraficoViewController *graph = [[GraficoViewController alloc] initWithNibName:@"GraficoViewController" bundle:nil]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:graph]; [self presentModalViewController:navigationController animated:YES]; [navigationController release]; Now the (BIG) question is: I have to hide the NagivationBar of my first UITableViewController inside my last view. I tried with this: [[[[[self parentViewController] parentViewController] parentViewController] navigationController] setNavigationBarHidden:YES]; but it doesn't work. Can someone tell me how I can find my ancestor View??? Thanks.

  • How to persist a very abstract data type between sessions: PHP

    - by Greelmo
    I have an abstract data type that behaves much like stack. It represents a history of "graph objects" made by a particular user. Each "graph object" holds one or more "lines", a date range, keys, and a title. Each "line" holds a sql generator configured for a particular subset of data in my db. I would like for these "histories" to be available to users between their sessions. It will be in the form of a tab that reads something like "most recent graphs". What do you believe to be the best way to persist this type of data between sessions. This application could get rather large, so efficiency is a concern. Thanks in advance.

  • How can I use Perl and RRD to plot ping times?

    - by ChrisMuench
    I'm trying to do my first rrd graph through Perl. I have tried RRD::Simple and rrds and just can't get either one to work. Here's what I have so far: use strict; use RRD::Simple (); # Create an interface object my $rrd = RRD::Simple-new( file = "server.rrd" ); # Put some arbitary data values in the RRD file for the same # 3 data sources called bytesIn, bytesOut and faultsPerSec. $rrd-create( EqSearch = "DERIVE", MfSearch = "DERIVE", EQCostBasis = "DERIVE", MFCostBasis = "DERIVE" ); $rrd-update( EqSearch = 2, MfSearch = 3, EQCostBasis = 10, MFCostBasis = 15 ); # Generate graphs: # /var/tmp/myfile-daily.png, /var/tmp/myfile-weekly.png # /var/tmp/myfile-monthly.png, /var/tmp/myfile-annual.png my %rtn = $rrd-graph( destination = "/Users/cmuench/Documents/Code/perl", title = "Server A", vertical_label = "", interlaced = "", periods = [qw(hour)] );

  • Internet Explorer discards cookie when printing?

    - by Gareth Saul
    I have an unusual issue with this page: http://reports.liftlogger.com/FleetReport/Status/ (username stackoverflow / password stackoverflow). The page loads and renders correctly in IE7/8. However, the graph does NOT print correctly. When printing or print previewing, the graph fails to load. I've identified that when printing, the browser attempts to reload the image, but does not send the ASPXAUTH authentication cookie along with it. This is required to generate the image (due to permission enforcement in the back-end). Can anyone help me identify why IE decides not to send this cookie, and is there a fix? Regards Gareth

  • 8-direction path finding algorithm

    - by frinkz
    I'm having trouble finding the right pathfinding algorithm for some AI I'm working on. I have players on a pitch, moving around freely (not stuck to a grid), but they are confined to moving in 8 directions (N NE E etc.) I was working on using A*, and a graph for this. But I realised, every node on the graph is equally far apart, and all the edges have the same weight - since the pitch is rectangular. And the number of nodes is enormous (being a large pitch, with them able to move between 1 pixel and another) I figured there must be another algorithm, optimised for this sort of thing?

  • Shortest-path algorithms which use a space-time tradeoff?

    - by Chris Mounce
    I need to find shortest paths in an unweighted, undirected graph. There are algorithms which can find a shortest path between two nodes, but this can take time. There are also algorithms for computing shortest paths for all pairs of nodes in the graph, but storing such a lookup table would take lots of disk space. What I'm wondering: Is there an algorithm which offers a space-time tradeoff that's somewhere between these two extremes? In other words, is there a way to speed up a shortest-path search, while using less disk space than would be occupied by an all-pairs shortest-path table? I know there are ways to efficiently store lookup tables for this problem, and I already have a couple of ideas for speeding up shortest-path searches using precomputed data. But I don't want to reinvent the wheel if there's already some established algorithm that solves this problem.

  • A couple questions using fwrite/fread with data structures

    - by Nazgulled
    Hi, I'm using fwrite() and fread() for the first time to write some data structures to disk and I have a couple of questions about best practices and proper ways of doing things. What I'm writing to disk (so I can later read it back) is all user profiles inserted in a Graph structure. Each graph vertex is of the following type: typedef struct sUserProfile { char name[NAME_SZ]; char address[ADDRESS_SZ]; int socialNumber; char password[PASSWORD_SZ]; HashTable *mailbox; short msgCount; } UserProfile; And this is how I'm currently writing all the profiles to disk: void ioWriteNetworkState(SocialNetwork *social) { Vertex *currPtr = social->usersNetwork->vertices; UserProfile *user; FILE *fp = fopen("save/profiles.dat", "w"); if(!fp) { perror("fopen"); exit(EXIT_FAILURE); } fwrite(&(social->usersCount), sizeof(int), 1, fp); while(currPtr) { user = (UserProfile*)currPtr->value; fwrite(&(user->socialNumber), sizeof(int), 1, fp); fwrite(user->name, sizeof(char)*strlen(user->name), 1, fp); fwrite(user->address, sizeof(char)*strlen(user->address), 1, fp); fwrite(user->password, sizeof(char)*strlen(user->password), 1, fp); fwrite(&(user->msgCount), sizeof(short), 1, fp); break; currPtr = currPtr->next; } fclose(fp); } Notes: The first fwrite() you see will write the total user count in the graph so I know how much data I need to read back. The break is there for testing purposes. There's thousands of users and I'm still experimenting with the code. My questions: After reading this I decided to use fwrite() on each element instead of writing the whole structure. I also avoid writing the pointer to to the mailbox as I don't need to save that pointer. So, is this the way to go? Multiple fwrite()'s instead of a global one for the whole structure? Isn't that slower? How do I read back this content? I know I have to use fread() but I don't know the size of the strings, cause I used strlen() to write them. I could write the output of strlen() before writing the string, but is there any better way without extra writes?

  • C# - Removing items from lists and all references to them.

    - by LiamV
    Hi there, I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node? Much appreciated, Liam

  • Real-time data on webpage with jQuery

    - by Steven Hepting
    I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to the page at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (this part is already complete). Update It sounds as though the solution is to use the jQuery.ajax() function ( http://api.jquery.com/jQuery.ajax/) with a function as the .complete callback that will schedule another request several seconds later to a URL that will return the data in JSON format. How can that method be scheduled? With the .delay() function?

  • Simple reduction (NP completeness)

    - by Allen
    hey guys I'm looking for a means to prove that the bicriteria shortest path problem is np complete. That is, given a graph with lengths and weights, I need to know if a there exists a path in the graph from s to t with total length <= L and weight <= W. I know that i must take an NP complete problem and reduce it to this one. We have at our disposal the following problems to choose from: 3-SAT, independent set, vertex cover, hamiltonian cycle, and 3-dimensional matching. Any ideas on which may be viable? thanks

  • Filter on button click D3.js?

    - by user1461701
    I'm working on a version of this bubble chart http://vallandingham.me/vis/gates/. As I'm using a different set of data - instead of the "All Grants" and "Grants by Year" buttons - I have one for 5 consecutive years - 2010, 2009 etc. My opening graph depicts the data for 2010 which is achieved by filtering the data from the .csv file , which contains the data for all 5 years. The problem I'm having is filtering and re-rendering the graph if another year is then chosen. I'd really appreciate it if anyone has any suggestions how I could simply achieve this? Thanks, Majella

  • NSNumberFormatter to display custom labels for 10^n (10000 -> 10k)

    - by Michele Colombo
    I need to display numbers on a plot axis. The values could change but I want to avoid too long numbers that will ruin the readability of the graph. My thought was to group every 3 characters and substitute them with K, M and so on (or a custom character). So: 1 - 1, 999 - 999, 1.000 - 1k, 1.200 - 1.2k, 1.280 - 1.2k, 12.800 - 12.8k, 999.999 - 999.9k, 1.000.000 - 1M, ... Note that probably I'll only need to format round numbers (1, 10, 1000, 1500, 2000, 10000, 20000, 30000, 100000, ...). Is that possibile with NSNumberFormatter? I saw that it has a setFormat method but I don't know how much customizable it is. I'm using NSNumberFormatter cause the graph object I use wants it to set label format and I want to avoid changing my data to set the label.

  • Does anyone know a better alternative to MS Excel's Solver?

    - by tundal45
    My company has to crunch a lot of data and part of the process involves running the solver and plotting a graph through resulting data points. Obviously there is a lot of copy and paste involved and the whole process is shaky, error prone and all round cluster-fudge. I was wondering if there was an alternative to the solver that can be used so that even if we have to use excel to plot the final graph, there will be a lot less data that needs to be copied and pasted back and forth. It would be great especially if the tool could be easily integrated into a .NET application but I am open to suggestions that may require a little bit of code-fu to get this to work. Thanks!

  • Depth First Search Basics

    - by cam
    I'm trying to improve my current algorithm for the 8 Queens problem, and this is the first time I'm really dealing with algorithm design/algorithms. I want to implement a depth-first search combined with a permutation of the different Y values described here: http://en.wikipedia.org/wiki/Eight_queens_puzzle#The_eight_queens_puzzle_as_an_exercise_in_algorithm_design I've implemented the permutation part to solve the problem, but I'm having a little trouble wrapping my mind around the depth-first search. It is described as a way of traversing a tree/graph, but does it generate the tree graph? It seems the only way that this method would be more efficient only if the depth-first search generates the tree structure to be traversed, by implementing some logic to only generate certain parts of the tree. So essentially, I would have to create an algorithm that generated a pruned tree of lexigraphic permutations. I know how to implement the pruning logic, but I'm just not sure how to tie it in with the permutation generator since I've been using next_permutation. Is there any resources that could help me with the basics of depth first searches or creating lexigraphic permutations in tree form?

  • GNUPlot: change axis labels

    - by Robert
    Dear Guys, I have used the following statement to get the GNUPlot plot a grah for me: plot "force.dat" using 1:2 title "Detroit" with lines, \ "force.dat" u 1:3 t "US Avergae" w linepoints and the "force.dat" looks like 2005 0 0 2006 104 51 2007 202 101 It draws nice graph for me. However, I don't like the X-axis, because it is labelled as 2005, 2005.5, 2006, 2006.5, 2007 etc.. However, those are year identifiers, I only want the 2005, 2006, 2007 etc., how could I get rid of the 2005.5, 2006.5 etc. labels in my GNUPlot graph? Thank you very much for your ideas.
