  • python and paramiko: how to check if end of ssh tunnel is still alive and reestablish if not?

    - by Christian
    Hello all, I'm trying to achieve the following: I have two hosts A and B. A establishes a remote port forwarding tunnel on B, i.e. B is the one a port is forwarded on to some where else and A is the one that sets up the tunnel. I tried the script rforward.py that ships with paramiko and it works very well so far. (I'm running rforward.py on A, which connects to B and forwards a port of B to somewhere else) However, when B is shutting down, A doesn't seem to recognize it. I'd rather like A to recognize that B is down and to try to reestablish the connection periodically in case B comes up again. Is there a way to do this? Thanks.

  • iOS4.2: TouchBegan does not draw more then one circle per sensed touch

    - by Christian
    Hi all, quick question (which might be a no-brainer for most here) :) My code below should draw a circle for every time touch that is recognised but although more than ones touches are sensed only one circle will drawn up at a time. Can anyone see any obvious issues? This method sits in the XYZViewControler.m class. TouchPoint.m is the class that defines the circle. Thanks a bundle for your help and redirects. Chris - (void) touchesBegan: (NSSet *) touches withEvent: (UIEvent *)event { NSSet * allTouches = [event allTouches]; // get all events for (UITouch * touch in touches) { TouchPoint * touchPoint = [[TouchPoint alloc] initWithFrame:CGRectMake(0, 0, circleWidth, circleWidth)]; touchPoint.center = [touch locationInView:[self view]]; touchPoint.color = [UIColor redColor]; touchPoint.backgroundColor = [UIColor whiteColor]; [[self view] addSubview: touchPoint]; [touchPoint release]; CFDictionarySetValue(touchMap, touch , touchPoint); } [[self view] setNeedsDisplay]; }

  • How can I create an editable combo box in HTML/Javascript?

    - by Christian Davén
    I need to let users select an item from a dropdown list, but also allow them to instead enter any text, even if it doesn't match an item in the list. How can I achieve this on a web page with HTML and Javascript? The select field doesn't let users enter text, and the input text field doesn't show the preferred alternatives. All items must show if the user opens the dropdown, so it can't be a simple auto-complete that only shows matching items.

  • PHP: Exception not caught by try ... catch

    - by Christian Brenner
    I currently am working on an autoloader class for one of my projects. Below is the code for the controller library: public static function includeFileContainingClass($classname) { $classname_rectified = str_replace(__NAMESPACE__.'\\', '', $classname); $controller_path = ENVIRONMENT_DIRECTROY_CONTROLLERS.strtolower($classname_rectified).'.controller.php'; if (file_exists($controller_path)) { include $controller_path; return true; } else { // TODO: Implement gettext('MSG_FILE_CONTROLLER_NOTFOUND') throw new Exception('File '.strtolower($classname_rectified).'.controller.php not found.'); return false; } } And here's the code of the file I try to invoke the autoloader on: try { spl_autoload_register(__NAMESPACE__.'\\Controller::includeFileContainingClass'); } catch (Exception $malfunction) { die($malfunction->getMessage()); } // TESTING ONLY $test = new Testing(); When I try to force a malfunction, I get the following message: Fatal error: Uncaught exception 'Exception' with message 'File testing.controller.php not found.' in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php:51 Stack trace: #0 [internal function]: application\Controller::includeFileContainingClass('application\Tes...') #1 D:\cerophine-0.0.1-alpha1\index.php(58): spl_autoload_call('application\Tes...') #2 {main} thrown in D:\cerophine-0.0.1-alpha1\application\libraries\controller.library.php on line 51 What seems to be wrong?

  • How do I find multiple matches with one regular expression?

    - by christian studer
    I've got the following string: response: id="1" message="whatever" attribute="none" world="hello" The order of the attributes is random. There might be any number of other attributes. Is there a way to get the id, message and world attribute in one regular expression instead of applying the following three one after another? / message="(.*?)"/ / world="(.*?)"/ / id="(.*?)"/

  • Use reflection to get a list of static classes

    - by Christian
    Hi, many questions are close, but none answers my problem... How do I use reflection in C# 3.5 to get all classes which are static from an assembly. I already get all Types defined, but there is no IsStatic property. Counting 0 constructors is really slow and did not work either. Any tips or a line of code? :-) Chris

  • SDL_BlitSurface() not displaying image?

    - by Christian Gonzalez
    So I'm trying to display a simply image with the SDL library, but when I use the function SDL_BlitSurface() nothing happens, and all I get is a black screen. I should also note that I have the .bmp file, the source, and the executable file all in the same directory. //SDL Header #include "SDL/SDL.h" int main(int argc, char* args[]) { //Starts SDL SDL_Init(SDL_INIT_EVERYTHING); //SDL Surfaces are images that are going to be displayed. SDL_Surface* Hello = NULL; SDL_Surface* Screen = NULL; //Sets the size of the window (Length, Height, Color(bits), Sets the Surface in Software Memory) Screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE); //Loads a .bmp image Hello = SDL_LoadBMP("Hello.bmp"); //Applies the loaded image to the screen SDL_BlitSurface(Hello, NULL, Screen, NULL); //Update Screen SDL_Flip(Screen); //Pause SDL_Delay(2000); //Deletes the loaded image from memory SDL_FreeSurface(Hello); //Quits SDL SDL_Quit(); return 0; }

  • .htaccess redirect umlaut domain

    - by Christian Engel
    I am trying to redirect requests from a umlaut domain to another domain. My following code works with ANY other domain, but not umlaut: <IfModule mod_rewrite.c> RewriteCond %{HTTPS} !=on RewriteCond %{HTTP_HOST} ^(www\.)?frankfurter-flöhe\.de/$ [NC] RewriteRule ^ http://kinderkultur-frankfurt.de/frankfurter-floehe-theaterprogramm.html [R=301,L] </IfModule> However, when I call the umlaut domain and copy it from google chromes address bar after that, I get this: http://xn--frankfurter-flhe-zwb.de/ Altough, if I use that obfruscated domain in my htaccess instead of the "real" umlaut domain, it doesn't work either. Does anybody have an idea how to match that domain?

  • Do I need to sanitize the callback parameter from a JSONP call?

    - by christian studer
    I would like to offer a webservice via JSONP and was wondering, if I need to sanitize the value from the callback parameter. My current server side script looks like this currently (More or less. Code is in PHP, but could be anything really.): header("Content-type: application/javascript"); echo $_GET['callback'] . '(' . json_encode($data) . ')'; This is a classic XSS-vulnerability. If I need to sanitize it, then how? I was unable to find enough information about what might be allowed callback strings.

    - by Christian
    We are a group of 3 people with computers who are inside a network that very closed and we don't have access to a bunch of ports. It would be benefitial to have a solution where we can also access the code from home. Is there a source control software that works well in a situation like this?

  • Is asp.net caching my sql results?

    - by Christian W
    I have the following method in an App_Code/Globals.cs file: public static XmlDataSource getXmlSourceFromOrgid(int orgid) { XmlDataSource xds = new XmlDataSource(); var ctx = new SensusDataContext(); SqlConnection c = new SqlConnection(ctx.Connection.ConnectionString); c.Open(); SqlCommand cmd = new SqlCommand(String.Format("select orgid, tekst, dbo.GetOrgTreeXML({0}) as Subtree from tblOrg where OrgID = {0}", orgid), c); var rdr = cmd.ExecuteReader(); rdr.Read(); StringBuilder sb = new StringBuilder(); sb.AppendFormat("&lt;node orgid=\"{0}\" tekst=\"{1}\"&gt;",rdr.GetInt32(0),rdr.GetString(1)); sb.Append(rdr.GetString(2)); sb.Append("&lt;/node&gt;"); xds.Data = sb.ToString(); xds.ID = "treedata"; rdr.Close(); c.Close(); return xds; } This gives me an XML-structure to use with the asp.net treeview control (I also use the CssFriendly extender to get nicer code) My problem is that if I logon on my pc with a code that gives me access on a lower level in the tree hierarchy (it's an orgianization hierarchy), it somehow "remembers" what level i logon at. So when my coworker tests from her computer with another code, giving access to another place in the tree, she get's the same tree as me. (The tree is supposed to show your own level and down.) I have added a html-comment to show what orgid it passes to the function, and the orgid passed is correct. So either the treeview caches something serverside, or the sqlquery caches it's result somehow... Any ideas? Sql function: ALTER function [dbo].[GetOrgTreeXML](@orgid int) returns XML begin RETURN (select org.orgid as '@orgid', org.tekst as '@tekst', [dbo].GetOrgTreeXML(org.orgid) from tblOrg org where (@orgid is null and Eier is null) or Eier=@orgid for XML PATH('NODE'), TYPE) end Extra code as requested: int orgid = int.Parse(Session["org"].ToString()); string orgname = context.Orgs.Where(q => q.OrgID == orgid).First().Tekst; debuglit.Text = String.Format("<!-- Id: {0} \n name: {1} -->", orgid, orgname); var orgxml = Globals.getXmlSourceFromOrgid(orgid); tvNavtree.DataSource = orgxml; tvNavtree.DataBind(); Where "debuglit" is a asp:Literal in the aspx file. EDIT: I have narrowed it down. All functions returns correct values. It just doesn't bind to it. I suspect the CssFriendly adapter to have something to do with it. I disabled the CssFriendly adapter and the problem persists... Stepping through it in debug it's correct all the way, with the stepper standing on "tvNavtree.DataBind();" I can hover the pointer over the tvNavtree.Datasource and see that it actually has the correct data. So something must be faulting in the binding process...

  • What's a better way to display a handle for resizing a view on iPhone / iPad?

    - by Christian
    I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.

  • ACCESS/VBA: How to create a ON/OFF type switch to allow record modification on a form ?

    - by Christian M
    I was using a combobox on my search form to select whether to consult or modify a record. To make it more user friendly (IMO), I put a togglebutton on a form, which controls the .AllowEdits property of my form. This way you can easily switch from reading to writing. However I run into a problem; once .AllowEdits is switched to false, the togglebutton is not clickable anymore ! What are my options ?

  • How can I sum number of rows of a table in SQL ORACLE?

    - by Christian Magro
    Dear community I have the follow instruction on SQL ORACLE: SELECT COUNT(FE_DAY) FROM TI_DATE WHERE (FE_MO = 02 AND FE_YEAR in ('2011', '2012')) GROUP BY FE_DAY In this instruction effectively obtain like SQL Answer a list of number that they sum=10 .But How can I don't show rows .I need only show the row's sum=10 I tried to apply the follow SQL instruction also: SELECT SUM(COUNT(FE_DAY)) FROM TI_DATE WHERE (FE_MO = 02 AND FE_YEAR in ('2011', '2012')) GROUP BY FE_DAY But the answer was 57, different of the number of rows, that I need.

  • NSTableView selection & highlights

    - by Christian
    I have a NSTableView as a very central part of my Application and want it to integrate more with the rest of it. It has only one column (it's a list) and I draw all Cells (normal NSTextFieldCells) myself. The first problem is the highlighting. I draw the highlight myself and want to get rid of the blue background. I now fill the whole cell with the original background color to hide the blue background, but this looks bad when dragging the cell around. I tried overriding highlight:withFrame:inView: and highlightColorWithFrame:inView: of NSCell but nothing happened. How can I disable automatic highlighting? I also want all rows/cells to be deselected when I click somewhere outside my NSTableView. Since the background / highlight of the selected cell turns gray there must be an event for this, but I can't find it. I let my cells expand on a double click and may need to undo this. So getting rid of the gray highlight is not enough. EDIT: I add a subview to the NSTableView when a cell gets double clicked and then resignFirstResponder of the NSTableView gets called. I tried this: - (BOOL)resignFirstResponder { if (![[self subviews] containsObject:[[self window] firstResponder]]) { [self deselectAll:self]; ... } return YES; } Besides that it's not working I would need to implement this method for all objects in the view hierarchy. Is there an other solution to find out when the first responder leaves a certain view hierarchy?

  • segmented reduction with scattered segments

    - by Christian Rau
    I got to solve a pretty standard problem on the GPU, but I'm quite new to practical GPGPU, so I'm looking for ideas to approach this problem. I have many points in 3-space which are assigned to a very small number of groups (each point belongs to one group), specifically 15 in this case (doesn't ever change). Now I want to compute the mean and covariance matrix of all the groups. So on the CPU it's roughly the same as: for each point p { mean[p.group] += p.pos; covariance[p.group] += p.pos * p.pos; ++count[p.group]; } for each group g { mean[g] /= count[g]; covariance[g] = covariance[g]/count[g] - mean[g]*mean[g]; } Since the number of groups is extremely small, the last step can be done on the CPU (I need those values on the CPU, anyway). The first step is actually just a segmented reduction, but with the segments scattered around. So the first idea I came up with, was to first sort the points by their groups. I thought about a simple bucket sort using atomic_inc to compute bucket sizes and per-point relocation indices (got a better idea for sorting?, atomics may not be the best idea). After that they're sorted by groups and I could possibly come up with an adaption of the segmented scan algorithms presented here. But in this special case, I got a very large amount of data per point (9-10 floats, maybe even doubles if the need arises), so the standard algorithms using a shared memory element per thread and a thread per point might make problems regarding per-multiprocessor resources as shared memory or registers (Ok, much more on compute capability 1.x than 2.x, but still). Due to the very small and constant number of groups I thought there might be better approaches. Maybe there are already existing ideas suited for these specific properties of such a standard problem. Or maybe my general approach isn't that bad and you got ideas for improving the individual steps, like a good sorting algorithm suited for a very small number of keys or some segmented reduction algorithm minimizing shared memory/register usage. I'm looking for general approaches and don't want to use external libraries. FWIW I'm using OpenCL, but it shouldn't really matter as the general concepts of GPU computing don't really differ over the major frameworks.
