  • Display graph without saving using pydot

    - by user506710
    Hello all I am trying to display a simple graph using pydot. My question is that is there any way to display the graph without writing it to a file as currently I use write function to first draw and then have to use the Image module to show the files. However is there any way that the graph directly gets printed on the screen without being saved ?? Also as an update I would like to ask in this same question that I observe that while the image gets saved very quickly when I use the show command of the Image module it takes noticeable time for the image to be seen .... Also sometimes I get the error that the image could'nt be opened because it was either deleted or saved in unavailable location which is not correct as I am saving it at my Desktop..... Does anyone know what's happening and is there a faster way to get the image loaded..... Thanks a lot....

  • Breaking out of .emacs script

    - by prosseek
    I use two emacs (Aquamcs and text based emacs) on my Mac. I normally use text based emacs for just editing something, so I don't want to load anything with it. What I came up with is to have the checking code in .emacs to exit/break if it's text based emacs (darwin system but not aquamacs). (when (and (equal system-type 'darwin) (not (boundp 'aquamacs-version))) (exit) ??? (break) ???? ) It seems to work, but I don't know how to break out of .emacs. How to do that? ADDED I just wanted to speed up in loading text based emacs on my mac, and I thought about breaking out as a solution. Based on the helpful answers, I came up with the following code that runs .emacs only when it's not a text based emacs. (setq inhibit-splash-screen t) (unless (null window-system)

  • Logging on to two sites simultaneously

    - by James Wakefield
    I want to log on to two sites simultaneously to enable a single sign on solution. We have a smallish wiki that is created with Apple wiki and we have an intranet site on a aspx cms system by Elcom. Both use Active Directory for credentials. Currently they are on different domains, but we could enable a rewrite using our load-balancer (Citrix Netscaler) or IIS. These sites are on different servers, one a mysterious Mac system and the other an IIS v6.0 on windows 2003. Now I am almost certain that a reverse proxy set up will solve this but I really just need someone to agree that this solves this issue, and if there are things I should look out for what they might be. I just want to have an invisible log on screen in an iframe and enter clone the user name and password using javascript.

  • best way to access/create SITE_ROOT and SERVER_ROOT values in PHP?

    - by Haroldo
    I need 2 different paths, one for includes and one for js/css etc. I'm using mod_rewrite. The below works fine.... Currently all my files contain this at the top define('SERVER_ROOT', 'C:/wamp/www/site_folder/'); define('SITE_ROOT', 'http://localhost/site_folder/'); and then files are called like so: require_once SERVER_ROOT . 'st_wd_assets/inc/func_st_wd.php'; <link rel="stylesheet" type="text/css" href="<?php echo SITE_ROOT;?>st_pages/user_area/css/user_area.css" media="screen"/> as you can probably see, it's going to be a massive chore to update the top of every file everytime i move versions between the localhost and my live server. What's the best/standard way of defining these ROOT values? I can't see a solution in the $_SERVER super global? Do people normally just use VirtualHosts? But then wouldn't it still be necessary to define ROOT constants?

  • C#.NET Problem with locking of page after writing stream to window.

    - by godlikeskills
    The code below works fine, the problem is the 1st two lines are appearing on screen. It basically loads the PDF but I can't see the btnAcceptProposal change name or become enabled. Tried a Thread for the load but it broke. Anyone got any ideas - it's a web application protected void btnPDFProposal_Click(object sender, EventArgs e) { btnAcceptProposal.Enabled = true; btnAcceptProposal.Text = "sss"; byte[] p = Order.Proposal; Response.AppendHeader("content-disposition", "attachment; filename=Proposal.pdf"); Response.ContentType = "Application/pdf"; Response.Clear(); Response.BinaryWrite(p); Response.End(); }

  • Have my UIPickerView having the same behavior than the keyboard.

    - by camilo
    Hi. So I have a UITableView where one of its rows is a UITextView. When the user is writing something to UITextView (using the keyboard) the user can scroll the tableview and select another cell. Everything works. When the user selects another cell, a datePicker appears, and the user can select a given date. I want the user to be able to scroll the tableView the same way like when the keyboard is on the screen. The problem here is that when I scroll with the picker, the table bounces back to the previous position (with some cells hidden by the picker). I assume that this happens because I add the picker to the main window, as a subview... but I'm honestly not sure... Where (and how) should I add my picker so that it "appears" where the keyboard appears? Not sure I was clear... Thanks a lot.

  • How should I display invalid options?

    - by mafutrct
    I've got a WinForms client-server app that displays various offers in a list. Every user (client) has a "rating". An offer consists of various data including a minimum and maximum rating. If a user's rating does not fall in that interval, he should not be able to take the offer. Of course I could just perform some server filtering and send a list of offers prefiltered for each user to the client application. But that would surely, and rightfully, lead to confused requests "Why isn't this offer showing up? I know it exists, it shows up on [other user]'s screen." How should I handle this? My favorite solution so far is to grey out the offer and add a tooltip "You can't take this offer because your rating is too high/low" while displaying greyed-out offers at the bottom of the list to leave the actually valid offers easily visible on top of the list.

  • Shortest distance between points on a toroidally wrapped (x- and y- wrapping) map?

    - by mstksg
    I have a toroidal-ish Euclidean-ish map. That is the surface is a flat, Euclidean rectangle, but when a point moves to the right boundary, it will appear at the left boundary (at the same y value), given by x_new = x_old % width Basically, points are plotted based on: (x_new, y_new) = ( x_old % width, y_old % height) Think Pac Man -- walking off one edge of the screen will make you appear on the opposite edge. What's the best way to calculate the shortest distance between two points? The typical implementation suggests a large distance for points on opposite corners of the map, when in reality, the real wrapped distance is very close. The best way I can think of is calculating Classical Delta X and Wrapped Delta X, and Classical Delta Y and Wrapped Delta Y, and using the lower of each pair in the Sqrt(x^2+y^2) distance formula. But that would involve many checks, calculations, operations -- some that I feel might be unnecessary. Is there a better way?

  • Animation with CGPoint in for loop

    - by user1066524
    I'm trying to do an animation where when a person clicks from point A to Point B on screen the object should slowly slide straight across (horizontally) from point A to Point B. I tried doing a for loop with something like: for (CGFloat i=previousPoint.x; i <= newPoint.x; i++){ [UIView animateWithDuration:10 delay:0 options:nil animations:^ { [magnifier removeFromSuperview]; magnifier = [[MagnifierView alloc] init]; CGPoint np = {i, newPoint.y}; magnifier.viewToMagnify = imageView; magnifier.touchPoint = np; [imageView addSubview:magnifier]; [magnifier setNeedsDisplay]; } completion:^(BOOL finished) { }]; } but for some reason it is moving it way up and then eventually to point B. sort of in a weird curve. how can I do this correctly?

  • Can I distort a bitmap image in Flash?

    - by drpepper
    Hi, what I would like to do is to take a loaded GIF file as a Bitmap, and then distort it by stretching and shrinking parts of it, so it would look like it got squished up against the screen. I'm pretty sure that there's no easy way in Flash to go beyond scaling and shearing, but I wonder if there might be some simple techniques to accomplish this kind of effect. By the way, I've also thought of pre-deforming the images in GIMP and saving them there, but I can't find a simple way to do it without learning their scripting language. Thanks for your help!

  • Method for demonstrating iPad application in online meetings

    - by competent_tech
    We have recently developed an iPad application and now need to start demonstrating it to customers and prospects as part of our overall product suite during webinars. As part of our Agile methodology, we also need to periodically review the application with key customers without having to distribute it since the application is not a standalone application and requires a connection to web services installed at each customer site. We have searched high and low for any solution that doesn't involve rooting the device but have been unable to find one. The most common suggestion seems to be to point a webcam at the device, but that comes across as very unprofessional. I know that there are VGA out adapters that can be plugged into the iPad and we have used these to present through a projector when the customer is physically present, but this is a relatively rare occurrence. Perhaps there are solutions that we are unaware of that can be used to send VGA output back into a desktop device for screen sharing?

  • providing a java servlet with information

    - by tom
    Hi, i am new to servlets. I made a simple hello world programme that prints those famous 2 words to the screen when i access the page via a browser using http://localhost:8080/mypath/path... My question is now, how do i provide a servlet with information? Specifically considering the fact that my c# programme calculates a lookup value for a global system, then the "java" servlet processes that and returns a set of results. I have done the reverse thanks to help on here, regarding calling a returned string from the java servlet in c#. However i am not sure how i go about providing the servlet information. Do i pass it via the url? Thank you

  • Snapping elements / conditional layouts

    - by Felix
    Sorry for the extremely bad title, I have no other idea what to call this question. What I'm trying to do is this: have a RelativeLayout which has two children: one with layout_centerInParent="true" one with layout_alignParentBottom="true" However, when the device is in landscape mode, element (1) appears slightly over or under element (2). But, element (1) has enough space above it to appear above element (2). How could I make the layout so that if the screen is too small to center element (1) and make both elements not overlap, then align element (1) above (as in layout_above) element (2)?

  • Can nohup change the result of a C++ code?

    - by Biga
    I am having this very weird behaviour with a C++ code: It gives me different results when running with and without 'nohup' (reproducible in cygwin and linux). I mean, if I get the same executable and run it like './run' or run it like 'nohup ./run out.log', I get different results! I use std::cout to output to screen, all lines ending with endl; I use ifstream for the input file; I use ofstream for output, all lines ending with endl. I am using g++ 4. Any idea what is going on?

  • C++ code visualization

    - by bobobobo
    A sort of follow up/related question to this. I'm trying to get a grip on a large code base that has hundreds and hundreds of classes and a large inheritance hierarchy. I want to be able to see the "main veins" of the inheritance hierarchy at a glance - not all the "peripheral" classes that only do some very specific / specialized thing. Visual Studio's "View Class Diagram" makes something that looks like a train and its sprawled horizontally across the screen and isn't very organized. You can't grok it easily. I've just tried doxygen and graphviz but the results are .. somewhat similar to Visual Studio. I'm getting sweet looking call graphs but again too much detail for what I'm trying to get. I need a quick way to generate the inheritance hierarchy, in some kind of collapsible view.

  • WPF - collapsing grid cells

    - by user553765
    Hi, I'm having some problems with the layout of buttons on a screen. There are a number of buttons with the visibility set to collapsed depending on certain criteria. Anyway, with the buttons sitting in a stackpanel, the contents determine the width of the buttons. Because these should share the same size, I put them in a grid where the columns are using the SharedSizeGroup. Having done this, buttons now all share the same width, the smallest width needed to display the button with the largest content. What it does mean though is that buttons don't display at the required position. That is - assume five buttons in columns 0-4 where the first button is collapsed, buttons should ideally all shift to the left so that they always occupy space left to right. Is there any way I can accomplish this or, if not, how can I get buttons in a stackpanel to share the same width? Any help is much appreciated.

  • Why are button sizes on Eclipse vs Device not the same.

    - by Mike Droid
    O.k....this is weird. I had my buttons looking fine last week, now something has changed. My buttons on the eclipse emulator are much larger than on my device (Droid 2.1). I checked my skin settings, screen size permissions, density factors....what am I missing? My skin is set to WVGA854, but when the app goes to the phone the buttons are smaller!? Text and pictures are fine...looking the same as the emulator...just the buttons are shrunk! Hmm....I know it has to be something simple...:)

  • Android Terminal and Log Dumping

    - by J3hova
    I am trying to send terminal commands programmaticly from an android activity. At the moment I'm using something like the following: Process process = null; DataOutputStream os = null; process = Runtime.getRuntime().exec("su"); os = new DataOutputStream(process.getOutputStream()); os.writeBytes("./data/program1\n"); os.writeBytes("./data/program2\n"); os.writeBytes("exit\n"); os.flush(); However, my program1 is failing to run successfully and I believe it is due to inadequate user permissions. Now for my question: Does anyone know how I can dump the terminal to a file and save it on the phone or sdcard? The program is tying into the terminal to feed it commands, I want to know a way to open a connection the otherway and access the (what is normally visual on a terminal screen) output.

  • Calling finish() After Starting a New Activity

    - by stormin986
    The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag? Is it correct to call finish() after calling startActivity() on the new activity? onCreate() { ... startActivity(new Intent(this, NextActivity.class)); finish(); ... } I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?
