Override default behavior of SPACE key in .net WinForms ListView

- by Axarydax

Hello, I'd like to implement some custom behavior of Space key in a ListView. Basically I'd like to toggle selected status of the item under cursor - that should be fairly simple this.FocusedItem.Selected = !this.FocusedItem.Selected; but alas, it also does the default action, which is to select the focused item. This way I am unable to 'unselect' the focused item. I've looked for similar problems and they suggest using PreviewKeyDown event, in which I would process the key and disallow the ListView to do its default action. But the PreviewKeyDown event argument has no "handled" property, so I cannot 'eat' this key.

Getting Out Of Memory: Java heap space, but while viewing heap space it max uses 50 MB

- by ikky

Hi! I'm using ASANT to run a xml file which points to a NARS.jar file. (i do not have the project file of the NARS.jar) I'm getting "java.lang.OutOfMemoryError: Java heap space. I used VisualVM to look at the heap while running the NARS.jar, and it says that it max uses 50 MB of the heapspace. I've set the initial and max size of heapspace to 512 MB. Does anyone have an ide of what could be wrong? I got 1 GB physical Memory and created a 5 GB pagefile (for test purpose). Thanks in advance.

C# WinForms StatusStrip - How do I reclaim the space from the "Grip"

- by Clyde

I've got a StatusStrip with a single ToolStripStatusLabel, Spring=true and a background color for notifications. The problem is that there's an ugly gray square on the right side of the status strip. After fiddling for a while, I realized this is the sizing grip (I had is set to SizingGrip=false, GripStyle=Hidden). Yet even with it hidden, it still hogs the space. I can't get any content on the status strip to extend all the way to the right. How would you work around this? Note I can't just set the backcolor of the StatusStrip because the Status Label changes colors and has some fading effects.

How can I force overflow: hidden to not use up my padding-right space

- by AlfaTeK

I have the following code: <div style="width: 100px; overflow: hidden; border: 1px solid red; background-color: #c0c0c0; padding-right: 20px; "> 2222222222222222222222111111111111111111111111113333333333333333333</div> (XHTML 1.0 transitional) What happens is that the padding-right doesn't appear, it's occupied by the content, which means the overflow uses up the padding right space and only "cuts off" after the padding. Is there any way to force the browser to overflow before the padding-right, which means my div will show with the padding right? What I get is the first div in the following image, what i want is something like the 2nd div: image

Howto project a planar polygon on a plane in 3d-space

- by sum1stolemyname

I want to project my Polygon along a vector to a plane in 3d Space. I would preferably use a single transformation matrix to do this, but I don't know how to build a matrix of this kind. Given the plane's parameters (ax+by+cz+d), the world coordinates of my Polygon. As stated in the the headline, all vertices of my polygon lie in another plane. the direction vector along which to project my Polygon (currently the polygon's plane's normal vector) goal -a 4x4 transformation matrix which performs the required projection, or some insight on how to construct one myself

Regex: Matching a space-joined list of words, excluding last whitespace

- by Jesper

How would I match a space separated list of words followed by whitespace and some optional numbers? I have this: >>> import re >>> m = re.match('(?P<words>(\w+\s+)+)(?P<num>\d+)?\r\n', 'Foo Bar 12345\r\n') >>> m.groupdict() {'num': '12345', 'words': 'Foo Bar '} I'd like the words group to not include the last whitespace(s) but I can't figure this one out. I could do a .strip() on the result but that's not as much fun :) Some strings to test and wanted result: 'Foo & Bar 555\r\n' => {'num': '555', 'words': 'Foo & Bar'} 'Hello World\r\n' => {'num': None, 'words': 'Hello World'} 'Spam 99\r\n' => {'num': 99, 'words': 'Spam'} 'Number 1 666\r\n' => {'num': 666, 'words': 'Number 1'}

Blank space after file extension -> weird FileInfo behaviour

- by Axarydax

Somehow a file has appeared in one of my directories, and it has space at the end of its extension - its name is "test.txt ". The weird thing is that Directory.GetFiles() returns me the path of this file, but I'm unable to retrieve file information with FileInfo class. The error manifests here: DirectoryInfo di = new DirectoryInfo("c:\\somedir"); FileInfo fi = di.GetFileSystemInfos("test*")[0] as FileInfo; //correctly fi.FullName is "c:\somedir\test.txt " //but fi.Exists==false (!) Is FileInfo class broken? Can I somehow retrieve information about this file? I really don't know how did that file appear on my file system, and I am unable to recreate some more of them. All of my attempts to create a new file with this type of extension have failed, but now my program is crashing when encoutering it. I can easily handle the exception when finding the file, but boy am I curious about this!

How to prevent Windows XP from stealing my input Ctrl-Space which is meant for Emacs

- by Dean

I am learning and using Emacs. What I found annoying is that Ctrl-Space input will be stolen by Windows XP to switch the language bar instead of setting the mark in Emacs. The "language bar" is the native input languages selection such as Chinese keyboard other than English keyboard. Is there a way to temporarily prevent XP from stealing it? I have disabled the language bar from "Regional and language options" from Control Panel but the problem still exists. It doesn't happen on my Windows 2000 desktop at office but it happens on my work Windows XP laptop. Thank you very much.

nested page-faulting of user-space address in Linux

- by shankar

Hi, I would like to know if it is functionally wrong to page-fault a user-space address when kernel is running fault-handler to bring in a user-page. OS is Linux 2.6.30 Assume that both user-addresses are valid ( falling within vma , rw permission ) for the task. When I check the kernel code, i find that the kernel does not mind the nested fault if the faulted-addresses are valid and the fault did not occur in atomic-context or in irq handler. (I dont think the answer is cpu-specific, but I would add that i am interested in arm and mips ). eg : The scenario can happen if I print stack-data from page-fault handler. thanks shankar

Huge file in Clojure and Java heap space error

- by trzewiczek

I posted before on a huge XML file - it's a 287GB XML with Wikipedia dump I want ot put into CSV file (revisions authors and timestamps). I managed to do that till some point. Before I got the StackOverflow Error, but now after solving the first problem I get: java.lang.OutOfMemoryError: Java heap space error. My code (partly taken from Justin Kramer answer) looks like that: (defn process-pages [page] (let [title (article-title page) revisions (filter #(= :revision (:tag %)) (:content page))] (for [revision revisions] (let [user (revision-user revision) time (revision-timestamp revision)] (spit "files/data.csv" (str "\"" time "\";\"" user "\";\"" title "\"\n" ) :append true))))) (defn open-file [file-name] (let [rdr (BufferedReader. (FileReader. file-name))] (->> (:content (data.xml/parse rdr :coalescing false)) (filter #(= :page (:tag %))) (map process-pages)))) I don't show article-title, revision-user and revision-title functions, because they just simply take data from a specific place in the page or revision hash. Anyone could help me with this - I'm really new in Clojure and don't get the problem.

How to increase Java heap space for a tomcat app

- by Ankur

There are lots of questions that ask this or a similar question. They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps. I read this page http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html and it says under the Tomcat section Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example, set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value) export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value) setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value) So I replaced the line set CATALINA_OPTS= with set CATALINA_OPTS=-Xms512m -Xmx512m But I still get the error.

Create hyperlink in django template of object that has a space

- by Ed

I am trying to create a dynamic hyperlink that depends on a value passed from a function: {% for item in field_list %} <a href={% url index_view %}{{ item }}/> {{ item }} </a> <br> {% endfor %} The problem is that one of the items in field_list is "Hockey Player". The link for some reason is dropping everything after the space, so it creates the hyperlink on the entire "Hockey Player", but the address is http://126.0.0.1:8000/Hockey How can I get it to go to http://126.0.0.1:8000/Hockey Player/ instead?

Color space - RGB and YCbCr question

- by HardCoder1986

Hello! I am now trying to understand how JPEG encoding works and everything seems fine except the color transformation part. Before attempting to do a DCT in JPEG algorithm, the image is transformed into YCbCr color space. To me this essentially means that we just (comparing to initial RGB image) take a chunk of color information and dispose it while applying the RGB -> YCbCr transformation. So, our encoding steps look generally like RGB -> YCbCr -> DCT -> Huffman. The decoding means inversing this process. And my question is - why does the image (for example, created and exported to JPEG) remain the same in terms of color, although we have to make inverse YCbCr -> RGB transform. Where does the disposed part of color information comes from or how is it handled?

Tab versus space indentation in C#

- by Lars Fastrup

I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

Problems crossing the boundary between protected greasemonkey execution space and the unsafeWindow l

- by Chilly

Hi guys. Here is my problem: I've registered some callbacks into a Yahoo event driven webpage (betfair.com market views) and am trapping the betsPlaced events with a handler. So far so simple. Next stage is to get the event back into greasemonkey land, and while I know that from greasemoney space you can call unsafeWindow.stuff, there is no reverse operation (by design). So if I want to send the contents of the event over, say, a cometd queue, my carefully set up jquery, greasemonkey, YUI2, betfair environment fails by telling me that unsafeWindow processes cant call GM_ajax stuff. This is obviously safe and sane, but it basically stops me doing what I want to do. Has anyone tried doing this (ignore the cometd stuff, just general ajax calls) and succeeded? I've had a look at pages like this: http://wiki.greasespot.net/0.7.20080121.0%2B_compatibility but it doesnt appear to work for all the calls.

Set asisde space for ADT when reading integers from file

- by That Guy

I'm using C to make maze solver. The program should be able read a maze from a text file containing a grid of 1 and 0 representing walls and paths. This file could be of any size as the user selects which maze to use. The program should then show the maze being solved. As the maze is being solved it should show where has been walked and how many steps have been taken. I have made an ADT called Cell containing a bool for wall or path and an integer for steps taken. I now need to populate a 2D array of Cells which means I need to set aside enough space to store a Cell for every integer in the maze file. What would be the best way to do this?

Faking a Single Address Space

- by dsimcha

I have a large scientific computing task that parallelizes very well with SMP, but at too fine grained a level to be easily parallelized via explicit message passing. I'd like to parallelize it across address spaces and physical machines. Is it feasible to create a scheduler that would parallelize already multithreaded code across multiple physical computers under the following conditions: The code is already multithreaded and can scale pretty well on SMP configurations. The fact that not all of the threads are running in the same address space or on the same physical machine must be transparent to the program, even if this comes at a significant performance penalty in some use cases. You may assume that all of the physical machines involved are running operating systems and CPU architectures that are binary compatible. Things like locks and atomic operations may be slow (having network latency to deal with and all) but must "just work".

Running python batch file that has a path with SPACE character

- by prosseek

The batch file is something like this, I put the python in some directory that has SPACE character in its path. C:\"Documents and Settings"\Administrator\Desktop\bracket\python\python C:\\"Documents and Settings"\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py When I run this one, I get this error. C:\Documents and Settings\Administrator\Desktop\bracket\python\python: can't ope n file 'C:\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\bra ckettest.py': [Errno 2] No such file or directory C:\Documents and Settings\Administrator\Desktop\bracket What might be wrong? Wrapping the path doesn't solve this problem. "C:\\Documents and Settings\\Administrator\\Desktop\\bracket\\[10,20]\\brackettest.py" Are the brackets ('[]') cause of the problem? On Mac, python works well with bracket character.

What will happen if on my DB server I'll run out of space?

I'm seeing a hugh difference of free disk space between df -h and du -sxh / I've understood in my question Resolving unix server disk space not adding up that du -sxh / is a better estimation as to when I will run out of disk space. Having said that, assuming in my case the above sentence will prove to be wrong and I will run soon out of disk space, what will happen? I assume the MySQL will fail INSERT queries, but other than that, will I just need to delete some files or will it be a problematic situation?
