• How to create plots in multiple windows and keep them seperate in R

  - by PaulHurleyuk

  Hello SOers, I'm sure this is an easy problem, but my google / help foo has failed me, so it's up to you. I have an R script that generates several plots, and I want to view all the plots on screen at once (in seperate windows), but I can't work out how to open multiple graphics windows. I'm using ggplot2, but I feel this is a more basic problem, so I'm just using base grapics for this simple example x<-c(1:10) y<-sin(x) z<-cos(x) dev.new() plot(y=y,x=x) dev.off() dev.new() plot(x=x,y=z) But this doesn't work. I'm on Windows if this matters (Windows + Eclipse + StatEt)

• Why is TreeSet<T> an internal type in .NET?

  - by Justin Niessner

  So, I was just digging around Reflector trying to find the implementation details of HashSet (out of sheer curiosity based on the answer to another question here) and noticed the following: internal class TreeSet<T> : ICollection<T>, IEnumerable<T>, ICollection, IEnumerable, ISerializable, IDeserializationCallback Without looking too deep into the details, it looks like a Self-Balancing Binary Search Tree. My question is, is there anybody out there with the insight as to why this class is internal? Is it simply because the other collection types use it internally and hide the complexities of a BST from the general masses...or am I way off base?

• Manage multiple Jlabel's events

  - by IMAnis_tn

  I have a left Panel with multiples Jlabels which i use them as buttons to change a Main Panel's content which is layouted with a CardLayout. I cant work perfectly with these events: mouseEntered : to make highlight effect to the jlabel mouseExited : to take off the highlight effect. mouseClicked : to change the content of the main Panel and start some threads The problem here that can't found an event or a method tell me that another Jlabel has been clicked so i can stop my threads started in the mouseClicked event, OR an event or method tell me that a JPanel in the CardLayout has been displayed or hidden.

• mySQL & Relational databases: How to handle sharding/splitting on application level?

  - by Industrial

  Hi everybody, I have thought a bit about sharding tables, since partitioning cannot be done with foreign keys in a mySQL table. Maybe there's an option to switch to a different relational database that features both, but I don't see that as an option right now. So, the sharding idea seems like a pretty decent thing. But, what's a good approach to do this on a application level? I am guessing that a take-off point would be to prefix tables with a max value for the primary key in each table. Something like products_4000000 , products_8000000 and products_12000000. Then the application would have to check with a simple if-statement the size of the id (PK) that will be requested is smaller then four, eight or twelve million before doing any actual database calls. So, is this a step in the right direction or are we doing something really stupid?

• Quality Design for Asynchronous WCF Services Calls in a Middle-Tier and Returning Data to UI Tier

  - by Perplexed

  I have a WPF application with a group of asynchronous WCF service calls all mashed into the code behind, complete with event handlers and everything, that I have to refactor to productionize and maintain. I want to separate concerns here for maintainability and all the other good reasons to do this, but I'm not sure exactly how to achieve this. Anybody have any good ideas on how to do this, or at least some links to put me in the right direction? My thinking: Create an "infrastructure" layer and reference the services there. Move the asynchronous event handlers into this layer. When an update is called, I will bubble up my own event with my own derivation of the EventArgs class that contains the data the UI will need. I'll have a fairly coupled hooking of the UI to the infrastructure layer as it will consume events I fire off upon completion of an asynchronous data call.

• How can we block the user from unchecking a DataGridView checkbox?

  - by hawbsl

  We have a DataGridViewCheckBox column bound to a boolean property in our class. The property setter has some logic which says that under certain conditions a True flag cannot be changed, ie, it stays checked forever. This is on a per record basis. So the entire column can't be readonly, only certain rows. Pseudo code: Public Property Foo() As Boolean Get Return _Foo End Get Set(ByVal value As Boolean) If _Foo And Bar And value = False Then //do nothing, in this scenario once you're true, you stay true Else _Foo = value End If End Set End Property Databinding is handling all of this fine, except that the checkbox is visibly cleared when it's clicked. Then, of course, when the binding / setter is fired (as you move off that cell) it is restored to its checked status per the underlying logic. Ultimately it doesn't matter too much but it's a clumsy bit of UI. How can we intercept the user's click and keep it checked?

• Is it possible to programmatically control c# health monitoring without using the web.config file?

  - by Adam

  I have developed my own custom provider for the health monitoring; however, I use parameters in the constructor and this is not allowed when using the health monitoring from the web.config file. Does anyone know if I can turn on/off the monitoring and have it watch properly through code (possibly in my global.asax file on application startup). Or, is it possible for me to create my own watcher that will do the same thing as the health monitor. Or, finally - can I just pass variables from the web.config setup (i'm not familiar with the public token part of the provider type declaration). Thanks in advance

• How do you tell if a string contains another string in Unix shell scripting?

  - by Matt

  Hi all, I want to write a Unix shell script that will do various logic if there is a string inside of another string. For example, if I am in a certain folder, branch off. Could someone please tell me how to accomplish this? If possible I would like to make this not shell specific (i.e. not bash only) but if there's no other way I can make do with that. #!/bin/sh CURRENT_DIR=`pwd` if [ CURRENT_DIR contains "String1" ] then echo "String1 present" elif [ CURRENT_DIR contains "String1" ] then echo "String2 present" else echo "Else" fi

• .NET Performance: Deep Recursion vs Queue

  - by JeffN825

  I'm writing a component that needs to walk large object graphs, sometimes 20-30 levels deep. What is the most performant way of walking the graph? A. Enqueueing "steps" so as to avoid deep recursion or B. A DFS (depth first search) which may step many levels deep and have a "deep" stack trace at times. I guess the question I'm asking is: Is there a performance hit in .NET for doing a DFS that causes a "deep" stack trace? If so, what is the hit? And would I better better off with some BFS by means of queueing up steps that would have been handled recursively in a DFS? Sorry if I'm being unclear. Thanks.

• Serving large generated files using Google App Engine?

  - by John Carter

  Hiya, Presently I have a GAE app that does some offline processing (backs up a user's data), and generates a file that's somewhere in the neighbourhood of 10 - 100 MB. I'm not sure of the best way to serve this file to the user. The two options I'm considering are: Adding some code to the offline processing code that 'spoofs' it as a form upload to the blob store, and going thru the normal blobstore process to serve the file. Having the offline processing code store the file somewhere off of GAE, and serving it from there. Is there a much better approach I'm overlooking? I'm guessing this is functionality that isn't well suited to GAE. I had thought of storing in the datastore as db.Text or Dd.Blob but there I encounter the 1 MB limit. Any input would be appreciated,

• DrawString only works in top-left part of form vb.net

  - by WillumMaguire

  Here is my code Public Class Form1 Public MyFormObject As Graphics = Me.CreateGraphics Public objFont = New System.Drawing.Font("arial", 20) Public a, b As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Randomize() For i = 1 To 10 a = CInt(Int(Rnd() * Me.Width)) b = CInt(Int(Rnd() * Me.Height)) MyFormObject.DrawString("text", objFont, System.Drawing.Brushes.Black, a, b) Next End Sub End Class As you can see, I have one button that draws the string "text" randomly in the form 10 times. My problem is that it will ONLY draw the string in the upper-left portion of the form, roughly 260x260 starting at 0,0. It literally cuts off the text if it goes beyond. Why is this? Shouldn't it work for the entire form?

• "Use windows xp style dpi scaling" disables automatic auto-hide of taskbar on W7. Workaround?

  - by Pelle

  We noticed that on W7 with DPI set to 125% or to 100% with ("Use windows xp style dpi scaling") turned off, our fullscreen mode (which sets the client rect of our window = desktop rect of the main monitor) no longer hides the task bar like it does for other settings. (The setting can be found in the Control Panel\Appearance and Personalization\Display section after clicking on the "Set custom text size (DPI)" link) I found the following interesting article: http://www.mathies.com/weblog/?p=908 So I set out to try to work around the bug in other means than manually hiding/restoring the taskbar visibility but so far I've failed and currently believe it's a bug in W7 (and possibly vista). The following applications also fail to work properly in fullscreen mode (the taskbar is still visible): * Microsoft Visual Studio 2008 * Microsoft Word 2007 * Adobe Reader 9.1.3 These apps work (probably by hiding the task bar through the WIN32 API): * Powerpoint Slide Show I also tried creating a brand new MFC-based app and use its "SetFullScreenMode()" functionality but it fails in the same way as all other apps on the list. Does anyone know of a workaround? Thanks, Per

• Handover document for complete systems

  - by viraptor

  Hi, I need to create a handover document for a fairly large system consisting of all the stuff you'd expect from a telecom deployment: many servers, database clusters which copy some data between them in specific ways, tons of log files, both off-the-shelf and locally developed software, scripts, network configurations, local know-how, etc. It's really got as many sysadmin-typical elements, as development ones. The target of this document are in the first place sysadmins who take over the day-to-day operation tasks and some problem resolving, and in the second place people who want to learn about the system in general. Is there some place I can learn about how to write something like that? It could just as easily be a 10 page "what's where", as a 500 pages book about "all things telephony". Maybe it should be more than one document really. Please link some useful resources / books I could use for this task. PS: this is intended to be internal only, customer interactions etc. are out of scope here

• Custom Error mode in Web.Config File

  - by Zerotoinfinite

  Hi All, I have deployed my application on server and Now I am getting this error: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. ~~~ I have defined custom error pages for my applicatio. Please help me, how to rectify this issue. Thanks in advance.

• Print styles: How to ensure image doesn't span a page break

  - by notJim

  This is a problem I've had a few times, and I'm not sure how to deal with it. When writing a print stylesheet, is there a way to ensure that an image is always only on a single page. An example of the behavior I'm seeing is below: Page 1 | | | (text text text) | | (text text text) | | ________________ | | | Top of image | | |____________________| ------page break------ ____________________ Page 2 | | Rest of image | | | |________________| | | … | What I'd like Page 1 | | | (text text text) | | (text text text) | | | | | |____________________| ------page break------ ____________________ | ________________ | | | Full image | | | | | | | |________________| | | … | All those times I bitching about floats in LaTeX, and here I am asking for the same functionality... Can this be done? I'm not necessarily concerned about it working in all browsers, since this is often just a one-off document I'm writing to be turned into a PDF.

• How to retrieve files/documents that are not found on the web server machine.

  - by jhorton

  I am trying to create an export feature for a user to be able to download documents into a zip file. I have the feature working when the files are located on my local and I can use an absolute path on my local. But after talking to the infrastructure team, I found out that the documents are not stored on the same machine as the web server but located at a server farm located off site. I can query the database which gives me a file path. But the path is more of a relative path. So can anyone help me understand how to use FileInfo with getting files from another machine. I believe the infrastructure team said there is a virtual drive set up to the outside server. Am I able to use a virtual path some how? Thanks.

• Question regarding CGRectIntersectsRect and rotated rectangular image

  - by user309030

  Hi guys, I've got a long rectangular image which is rotated at different kind of angles. However the frame of the rectangular image does not rotate along with the image and instead, the rotation causes the frame to to become larger to fit the rotated image. So when I used CGRectIntersectsRect, the collision detection is totally off because the other image colliding with the rectangular image will collide before it even reaches the visible area of the rect image. In case you don't really know what I'm talking about, have a look at the ascii drawing: normal rectangular image frame, O - pixels, |, – - frame |----------| |OOOOOOOOOO| |----------| after rotation |----------| |O | | O | | O | | O | | O | | O | | O | | O | | O | |----------| I've read through some of the collision articles but all of them are talking about collision with a normal straight rectangle and what I really want is collision with a slanted image, preferably pixel collision detection. TIA for any suggestions made.

• ant cpptask with ivy

  - by AC

  A company I am working for, has some c binaries build with ant using cpptask. They use ivy to retrieve shared c libraries every time we start a build which wastes a significant amount of time comparing the revisions and downloading, when then only need to be download if the header files have changed. I have added a target which sets a var, which causes the build to skip over the ivy steps but I'd like a better solution. I see that cpptask creates a file history.xml and only rebuilds to binary if any of the sources have change. I'd like to know if there is way to independently test if the binary needs to build, and it does, I'd like it fire off the ivy targets. I'd also like for a variable to be set if the binary was rebuilt so that I can conditionally start an rpm generation task

• How to grab the lines AFTER a matched line in python

  - by toofly

  Hi All, I am an amateur using Python on and off for some time now. Sorry if this is a silly question, but I was wondering if anyone knew an easy way to grab a bunch of lines if the format in the input file is like this: " Heading 1 Line 1 Line 2 Line 3 Heading 2 Line 1 Line 2 Line 3 " I won't know how many lines are after each heading, but I want to grab them all. All I know is the name, or a regular expression pattern for the heading. The only way I know to read a file is the "for line in file:" way, but I don't know how to grab the lines AFTER the line I'm currently on. Hope this makes sense, and thanks for the help!

• UIImageView is clipping a pixel of the bottom of my UIImage...?

  - by akaii

  I'm not sure what might be causing this, but UIImageView occasionally clips off about a pixel or 2 from the bottom of some square/rectangular UIImages I'm using as subviews for UITableViewCells. These UIImageViews are well within the borders of the cell, so it shouldn't be due to cliptobounds. There seems to be no consistency or pattern to which images are being clipped, nor when they're clipped, other than that it only happens to (or is only noticable in) square/rectangular icons, and only ones that are parented to UITableViewCells (or their subclasses). I'm having trouble reproducing the problem consistently, which is why I haven't posted any code this time. Has anyone encountered something similar to this before? I've encountered a similar bug that involved floating point values for origin/size being interpreted weirdly... but that doesn't seem to be the cause of this particular problem. I don't need a specific solution at this point, I'm just making sure I haven't missed any well-known bugs or documented problems that involve UIImageView.

• How can I receive messages using over http without MSMQ

  - by pduncan

  I need a reliable messaging framework that runs over http/https (due to client security requirements) and that doesn't use MSMQ (because some clients will use Windows XP Home). The clients only need to be able to receive messages, not send them. We already have a message queue on the server for each user, and the receivers have been getting messages by connecting to an HttpHandler on the server and getting a Stream from WebResponse.GetResponseStream() We keep this stream open, and pull messages off of it using Stream.Read(). This MOSTLY works, but Stream.Read() is a blocking call, and we can't reliably interrupt it. We need to be able to stop and start the receiver without losing messages, but the old stream often hangs around, even after we call Thread.Abort on its thread. Any suggestions?

• Unreachable code detected in case statement

  - by alex

  I have a code: protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { switch (keyData) { case Keys.Alt|Keys.D1: if (this._condition1) { return true; } else { return base.ProcessCmdKey(ref msg, keyData); } break; case Keys.Control |Keys.U: if (this._condition2) { return true; } else { return base.ProcessCmdKey(ref msg, keyData); } break; default: return base.ProcessCmdKey(ref msg, keyData); } return true; It gives me "unreachable code detected" warning on breaks. Is it good practice not to use break operator here ? I don't want to turn off "unreachable code detected" warning. PS: There are many case in my ProcessCmdKey method.

• Apache server-side files caching via .htaccess?

  - by purpler

  Hi, I'm starting new website and gonna include several JS libs and would like to know how .htaccess file template should look like with caching of media and JS files on? Whats better for compression, GZip or Deflate? Is it better/faster solution to serve those JS libs of the Google CDN perhaps then locally? I'm asking CDN question since some of scripts served off GoogleCDN are potentially going to update and eventually break the website layout so i thought it would be better for me to host them locally and cache via webserver if its going to work with same/near-same speed.

• How to break up HTML documents into pages for ebook?

  - by radnoise

  For an iPhone ebook application I need to break arbitrarily long HTML documents up into pages which fit exactly on one screen. If I simply use UIWebView for this, the bottom-most lines tend to get displayed only partly: the rest disappears off the edge of the view. So I assume I would need to know how many complete lines (or characters) would be displayed by the UIWebView, given the source HTML, and then feed it exactly the right amount of data. This probably involves lots of calculation, and the user also needs to be able to change fonts and sizes. I have no idea if this is even possible, although apps like Stanza take HTML (epub) files and paginate them nicely. It's a long time since I looked at JavaScript, would that be an option worth looking at? Any suggestions very much appreciated!

We install the .NET Framerwork to the local PCs and also set the full trust via the following: %windir%\Microsoft.NET\Framework\v1.1.4322\caspol -pp off -cg LocalIntranet_Zone FullTrust This has worked fine on all PCs to date however now we have a few new PCs with Win7 and the process no longer is working. The app will run fine from a local drive in Win7 but running the networked copy results in a general exception error. Any ideas on how to get this to work under Win7?
