• Extracting a .app from a zip file in Python, using ZipFile

  - by Yakattak

  I'm trying to extract new revisions of Chromium.app from their snapshots, and I can download the file fine, but when it comes to extracting it, ZipFile either extracts the chrome-mac folder within as a file, says that directories don't exist, etc. I am very new to python, so these errors make little sense to me. Here is what I have so far. import urllib2 response = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/LATEST') latestRev = response.read() print latestRev # we have the revision, now we need to download the zip and extract it latestZip = urllib2.urlopen('http://build.chromium.org/buildbot/snapshots/chromium-rel-mac/%i/chrome-mac.zip' % (int(latestRev)), '~/Desktop/ChromiumUpdate/%i-update' % (int(latestRev))) #declare some vars that hold paths n shit workingDir = '/Users/slehan/Desktop/ChromiumUpdate/' chromiumZipPath = '%s%i-update.zip' % (workingDir, (int(latestRev))) chromiumAppPath = 'chrome-mac/' #the path of the chromium executable within the zip file chromiumAppExtracted = '%s/Chromium.app' % (workingDir) # path of the extracted executable output = open(chromiumZipPath, 'w') #delete any current file there output.write(latestZip.read()) output.close() # we have the .zip now we need to extract the Chromium.app file, it's in ziproot/chrome-mac/Chromium.app import zipfile, os zippedFile = open(chromiumZipPath) zippedChromium = zipfile.ZipFile(zippedFile, 'r') zippedChromium.extract(chromiumAppPath, workingDir) #print zippedChromium.namelist() zippedChromium.close() #zippedChromium.close() Any ideas?

• Home folder only SFTP connection has limited access

  - by Tomasz Durka

  I have configured sftp access for user using this guide: Linux shell to restrict sftp users to their home directories? I have problem though. I have taken all steps. I have chown'ed root:user the home folder and I set permissions to 755. I can login normally using SFTP, however I can NOT transfer files, can NOT mkdir directories. If I change permissions to 777 it's ok do edit everything. However this is the thing I don't want. Additionally after exiting sftp and reconnecting then connection is reset by peer (due to setting 777). Anyone had similar problem? What I am doing wrong?

• Where can I find logs for SFTP?

  - by Jake

  I'm trying to set up sftp-server but the client is getting an error, Connection closed by server with exitcode 1 /var/log/auth.log (below) doesn't help much, how can I find out what the error is? I'm running Ubuntu 10.04.1 LTS sshd[27236]: Accepted password for theuser from (my ip) port 13547 ssh2 sshd[27236]: pam_unix(sshd:session): session opened for user theuser by (uid=0) sshd[27300]: subsystem request for sftp sshd[27236]: pam_unix(sshd:session): session closed for user theuser Update: I've been prodding this for a while now, I've got the sftp command on another server giving me a more useful error. Request for subsystem 'sftp' failed on channel 0 Couldn't read packet: Connection reset by peer Everything I've found on the net suggests this id a problem with sftp-server but when I remove the chroot from sshd config I can access the system. I assume this means sftp-server is accessible and set up correctly.

• Are MEF's ComposableParts contracts instance-based?

  - by Dave

  I didn't really know how to phrase the title of my questions, so my apologies in advance. I read through parts of the MEF documentation to try to find the answer to my question, but couldn't find it. I'm using ImportMany to allow MEF to create multiple instances of a specific plugin. That plugin Imports several parts, and within calls to a specific instance, it wants these Imports to be singletons. However, what I don't want is for all instances of this plugin to use the same singleton. For example, let's say my application ImportManys Blender appliances. Every time I ask for one, I want a different Blender. However, each Blender Imports a ControlPanel. I want each Blender to have its own ControlPanel. To make things a little more interesting, each Blender can load BlendPrograms, which are also contained within their own assemblies, and MEF takes care of this loading. A BlendProgram might need to access the ControlPanel to get the speed, but I want to ensure that it is accessing the correct ControlPanel (i.e. the one that is associated with the Blender that is associated with the program!) This diagram might clear things up a little bit: As the note shows, I believe that the confusion could come from an inherently-poor design. The BlendProgram shouldn't touch the ControlPanel directly, and instead perhaps the BlendProgram should get the speed via the Blender, which will then delegate the request to its ControlPanel. If this is the case, then I assume the BlendProgram needs to have a reference to a specific Blender. In order to do this, is the right way to leverage MEF and use an ImportingConstructor for BlendProgram, i.e. [ImportingConstructor] public class BlendProgram : IBlendProgram { public BlendProgram( Blender blender) {} } And if this is the case, how do I know that MEF will use the intended Blender plugin?

• unusual webpage access problem

  - by user28163

  This is one of the weirdest problems I've ever seen and I'm out of ideas. I cannot access a couple of websites from my home pc (for 3-4 days now), or at least they go really really slow ~700b/s I can access these same websites fine from my laptop from same IP address. - The websites originate from different countries and are huge popular sites. - I have tried both my PC's network cards. - I have reformatted my PC. - I have reset my router to factory settings. - I have created virtual computers on my PC, and from inside those I cannot access the webpages. - I have flushed my dns. - I tried specifying my dns server addresses to 8.8.8.8 and 8.8.4.4. I can only access the webpages using my PC, if I first connect to an outside VPN. Again, these sites work fine on the 2 other pcs in this house (same ISP and internet connection). help plz :)

• LED Display control software

  - by user978733

  My university bought new big led display from chinese manufacturers. What I want to do is, show some visualizations (like Windows Media Player, Winamp, Itunes ... does) with music. I'd just drag the application window to show on screen But main problem is,The software that controls it (called "Led Vision") doesn't support showing applications' windows: It shows limited types of the files, such as, powerpoint presentation, video files, picture files.. etc. Now the question is, where I can find the visualization video files? something that created in After Effects, looks like that:

• I'm looking for an online ASP.NET tutor.

  - by pkiyan

  $15/hr. I know it's not much but... Hi. I'm looking for an ASP.NET tutor. I want to use a remote desktop application so we can see each others screens and use Skype or phone to communicate with. You won't need to come up with any lessons or anything like that. I was thinking we could spend an hour or two each time we logged in to build a decent sized website from scratch. That's basically it. I'm a beginner with about 2 months experience with ASP.NET so we won't have to start from the very beginning, but pretty close. I wanted this site to have a little complexity to it and not just a website for beginners, but something I could study for a while. I'll pay you through PayPal or some other method if you prefer. By the way, it doesn't have to be a website that we work on together. I'll listen to other suggestions too. Maybe we could use an open source site/app to walk-through and study and modify. I've looked at 'My Web Pages Starter Kit 1.30', 'SubText 2.1.2', 'nopCommerce 1.5', and some others. They were all beyond me, and I couldn't make sense of any of the source code. But if you use and are really familiar with an open source app/site that I can download, we could study that. Here are some technical specs about the site I'd like to build/study: ASP.NET 2.0+ (preferably 3.5+, but I don't really care) C# / VB.NET ( don't really care, I suck at both. This is more about ASP.NET and helping me understand the structure of an ASP.NET website and the .NET framework in general. ) SQL Server ( I have SQL Server 2008 express and would someday like to learn how to use this thing. ) JavaScript / AJAX ( at least some use of this ) XML ( basically, I'd like to spend some time in the web.config file, and have some sense of what's going on in there. ) ASP.NET Folders ( I'd like to work with all of the ASP.NET folders if possible: App_Code, App_GlobalResources, etc.. and understand what does/doesn't go in them. Hopefully we can build more than one theme too. ) Assemblies ( how do you create a .dll and use it across different websites? maybe you could suggest a third party .dll that we could use ) Web Service ( I read about this once but didn't really get it ) I can't think of anything else but the above will definitely keep me busy. Hopefully we could make use of a lot of the server controls too (the nav controls gave me a headache when I tried customizing them). Is someone willing to help? I'll pay through PayPal 15 bucks an hour. I live in the Dallas, Texas (US) area so we'd have to synchronize time zones and agree on a day(s)/time of the week. I prefer working at night and on the weekends because I work during the week but whatever your schedule allows too. If you'd like to help me, can you post: years of experience with ASP.NET, your Time zone and time you're available and any ideas you might have about how you'd like to tutor? THANK YOU.

• Mac Terminal: changed my shell, now can't start it

  - by kch

  I installed bash 4.0 via MacPorts, then used sudo chsh -s /opt/local/bin/bash my_user to change my shell. Before that I tried just running plain chsh without sudo, but it wouldn't allow me to change my shell to that path. Now when I try to start Terminal I'm getting a message that my shell has an illegal value, so Terminal won't start. I click Quit, and, unsurprisingly but annoyingly, it quits immediately. How do I reset my shell so I can start Terminal again? How do I set my shell to bash installed via MacPorts in a way that it'll work? Why does Terminal think my shell is illegal anyway? Is it siding with the neo-prohibitionists? Mac OS X 10.5.8. Everything super mega up-to-date.

• [Flex 4 and .Net] Retrieving tables from SQL database

• How can I get black window borders in Windows 8?

  - by sean e

  In Windows 8, when I go into Control Panel\Appearance and Personalization\Personalization\Window Color and Appearance the amount of control over window colors is greatly reduced as compared to Windows 7. The color controls do not allow you to make Window borders display in black. Is there some other way to set the window border color in Windows 8? Edit 1: Clearly the standard way does not work in Windows 8. The question is, is there another way? Perhaps through the registry for example? Edit 2: I tried copying the values in HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM from my Win7 system to the Win8 system without success (killing the 2 DWM processes after each change - they are automatically restarted and do use the new values).

• Router 2wire, Slackware desktop in DMZ mode, iptables policy aginst ping, but still pingable

  - by skriatok

  I'm in DMZ mode, so I'm firewalling myself, stealthy all ok, but I get faulty test results from Shields Up that there are pings. Yesterday I couldn't make a connection to game servers work, because ping block was enabled (on the router). I disabled it, but this persists even due to my firewall. What is the connection between me and my router in DMZ mode (for my machine, there is bunch of others too behind router firewall)? When it allows router affecting if I'm pingable or not and if router has setting not blocking ping, rules in my iptables for this scenario do not work. Please ignore commented rules, I do uncomment them as I want. These two should do the job right? iptables -A INPUT -p icmp --icmp-type echo-request -j DROP echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all Here are my iptables: #!/bin/sh # Begin /bin/firewall-start # Insert connection-tracking modules (not needed if built into the kernel). #modprobe ip_tables #modprobe iptable_filter #modprobe ip_conntrack #modprobe ip_conntrack_ftp #modprobe ipt_state #modprobe ipt_LOG # allow local-only connections iptables -A INPUT -i lo -j ACCEPT # free output on any interface to any ip for any service # (equal to -P ACCEPT) iptables -A OUTPUT -j ACCEPT # permit answers on already established connections # and permit new connections related to established ones (eg active-ftp) iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT #Gamespy&NWN #iptables -A INPUT -p tcp -m tcp -m multiport --ports 5120:5129 -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 6667 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 28910 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29900 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29901 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p tcp -m tcp --dport 29920 --tcp-flags SYN,RST,ACK SYN -j ACCEPT #iptables -A INPUT -p udp -m udp -m multiport --ports 5120:5129 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 6500 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 27900 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 27901 -j ACCEPT #iptables -A INPUT -p udp -m udp --dport 29910 -j ACCEPT # Log everything else: What's Windows' latest exploitable vulnerability? iptables -A INPUT -j LOG --log-prefix "FIREWALL:INPUT" # set a sane policy: everything not accepted > /dev/null iptables -P INPUT DROP iptables -P FORWARD DROP iptables -P OUTPUT DROP iptables -A INPUT -p icmp --icmp-type echo-request -j DROP # be verbose on dynamic ip-addresses (not needed in case of static IP) echo 2 > /proc/sys/net/ipv4/ip_dynaddr # disable ExplicitCongestionNotification - too many routers are still # ignorant echo 0 > /proc/sys/net/ipv4/tcp_ecn #ping death echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all # If you are frequently accessing ftp-servers or enjoy chatting you might # notice certain delays because some implementations of these daemons have # the feature of querying an identd on your box for your username for # logging.

• How do I launch a WPF app from command.com. I'm getting a FontCache error.

  - by jttraino

  I know this is not ideal, but my constraint is that I have a legacy application written in Clipper. I want to launch a new, WinForms/WPF application from inside the application (to ease transition). This legacy application written in Clipper launches using: SwpRunCmd("C:\MyApp\MyBat.bat",0) The batch file contains something like this command: C:\PROGRA~1\INTERN~1\iexplore "http://QASVR/MyApp/AppWin/MyCompany.MyApp.AppWin.application#MyCompany.MyApp.AppWin.application" It is launching a WinForms/WPF app that is we deploy via ClickOnce. Everything has been going well until we introduced WPF into the application. We were able to easily launch from the legacy application. Since we have introduced WPF, however, we have the following behavior. If we launch via the Clipper application first, we get an exception when launching the application. The error text is: The type initializer for 'System.Windows.FrameworkElement' threw an exception. at System.Windows.FrameworkElement..ctor() at System.Windows.Controls.Panel..ctor() at System.Windows.Controls.DockPanel..ctor() at System.Windows.Forms.Integration.AvalonAdapter..ctor(ElementHost hostControl) at System.Windows.Forms.Integration.ElementHost..ctor() at MyCompany.MyApp.AppWin.Main.InitializeComponent() at MyCompany.MyApp.AppWin.Main..ctor(String[] args) at MyCompany.MyApp.AppWin.Program.Main(String[] args) The type initializer for 'System.Windows.Documents.TextElement' threw an exception. at System.Windows.FrameworkElement..cctor() The type initializer for 'System.Windows.Media.FontFamily' threw an exception. at System.Windows.Media.FontFamily..ctor(String familyName) at System.Windows.SystemFonts.get_MessageFontFamily() at System.Windows.Documents.TextElement..cctor() The type initializer for 'MS.Internal.FontCache.Util' threw an exception. at MS.Internal.FontCache.Util.get_WindowsFontsUriObject() at System.Windows.Media.FontFamily.PreCreateDefaultFamilyCollection() at System.Windows.Media.FontFamily..cctor() Invalid URI: The format of the URI could not be determined. at System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind) at System.Uri..ctor(String uriString, UriKind uriKind) at MS.Internal.FontCache.Util..cctor() If we launch the application via the URL (in IE) or via the icon on the desktop first, we do not get the exception and application launches as expected. The neat thing is that whatever we launch with first determines whether the app will launch at all. So, if we launch with legacy first, it breaks right away and we can't get the app to run even if we launch with the otherwise successful URL or icon. To get it to work, we have to logout and log back in and start it from the URL or icon. If we first use the URL or the icon, we have no problem launching from the legacy application from that point forward (until we logout and come back in). One other piece of information is that we are able to simulate the problem in the following fashion. If we enter a command prompt using "cmd.exe" and execute a statement to launch from a URL, we are successful. If, however, we enter a command prompt using "command.com" and we execute that same statement, we experience the breaking behavior. We assume it is because the legacy application in Clipper uses the equivalent of command.com to create the shell to spawn the other app. We have tried a bunch of hacks like having command.com run cmd.exe or psexec and then executing, but nothing seems to work. We have some ideas for workarounds (like making the app launch on startup so we force the successful launch from a URL, making all subsequent launches successful), but they all are sub-optimal even though we have a great deal of control over our workstations. To reduce the chance that this is related to permissions, we have given the launching account administrative rights (as well as non-administrative rights in case that made a difference). Any ideas would be greatly-appreciate. Like I said, we have some work arounds, but I would love to avoid them. Thanks!

• WebClient.DownloadDataAsync is freezing my UI

  - by Matías

  Hi, I have in my Form constructor, after the InitializeComponent the following code: using (WebClient client = new WebClient()) { client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(client_DownloadDataCompleted); client.DownloadDataAsync("http://example.com/version.txt"); } When I start my form, the UI doesn't appears till client_DownloadDataCompleted is raised. The client_DownloadDataCompleted method is empty, so there's no problem there. What I'm doing wrong? How is supposed to do this without freezing the UI? Thanks for your time. Best regards.

• WCF RIA Services Custom Type with Collection of Custom Types

  - by Blakewell

  Is it possible to have a custom type within a custom type and have the result returned via WCF RIA services? I have the following two classes below, but I can't gain access to the Verticies property within the Polygon class. I assume it is because it is a custom class, or something to do with it being a List collection. Polygon Class public class Polygon { public Polygon() { _vertices = new List<Location>(); } private int _id; [Key] public int Id { get; set; } private List<Location> _vertices; public List<Location> Vertices { get { return _vertices; } set { _vertices = value; } } } Location Class public class Location { public Location() { } /// <summary> /// Default constructor for creating a Location object /// </summary> /// <param name="latitude"></param> /// <param name="longitude"></param> public Location( double latitude, double longitude ) { _latitude = latitude; _longitude = longitude; } private int _id; [Key] public int Id { get { return _id; } set { _id = value; } } private double _latitude; /// <summary> /// Latitude coordinate of the location /// </summary> public double Latitude { get { return _latitude; } set { _latitude = value; } } private double _longitude; /// <summary> /// Longitude coordiante of the location /// </summary> public double Longitude { get { return _longitude; } set { _longitude = value; } } }

• How can I map stored procedure result into a custom class with linq-to-sql?

  - by Remnant

  I have a stored procedure that returns a result set (4 columns x n Rows). The data is based on multiple tables within my database and provides a summary for each department within a corporate. Here is sample: usp_GetDepartmentSummary DeptName EmployeeCount Male Female HR 12 5 7 etc... I am using linq-to-sql to retrieve data from my database (nb - have to use sproc as it is something I have inherited). I would like to call the above sproc and map into a department class: public class Department { public string DeptName {get; set;} public int EmployeeCount {get; set;} public int MaleCount {get; set;} public int FemaleCount {get; set;} } In VS2008, I can drag and drop my sproc onto the methods pane of the linq-to-sql designer. When I examine the designer.cs the return type for this sproc is defined as: ISingleResult<usp_GetDepartmentSummaryResult> What I would like to do is amend this somehow so that it returns a Department type so that I can pass the results of the sproc as a strongly typed view: <% foreach (var dept in Model) { %> <ul> <li class="deptname"><%= dept.DeptName %></li> <li class="deptname"><%= dept.EmployeeCount %></li> etc... Any ideas how to achieve this? NB - I have tried amending the designer.cs and dbml xml file directly but with limited success. I admit to being a little out of my depth when it comes to updating those files directly and I am not sure it is best practice? Would be good to get some diretion. Thanks much

• make IIS 7.5 cache static content files over diferent pages

  - by Achilles

  On a Windows 2008 R2, using DNS and IIS I've established my development test server; i.e. I'll have a web application that I can browse on http://test.dev I've moved all the static content files like images, js files and css files into another application which is visible on http://cdn.test.dev test.dev, uses cdn.test.dev urls like http://cdn.test.dev/js/jquery.js to load js, css and images. When I first load "~/" of test.dev, all files will load with a response code of 200; when I press F5 in Firefox, all files, except the "~/default.aspx", will load with 304 response code; but pressing Ctrl+F5 loads them again with a 200 code; if I browse another url like "~/pages/" in test.dev, all of those static files will reload with a 200 code... Is this normal or I'm doing something wrong? Actually, I'm looking for a behavior like this: I want the client to load http://cdn.test.dev/js/jquery.js, only once. I want the client's browser to use this jquery.js file, from cache, in all other pages of test.dev Is this possible? This is the web.config file I have in the root directory of cdn.test.dev: <configuration> <system.webServer> <caching> <profiles> <add extension=".png" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".gif" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".jpg" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".js" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".css" policy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> <add extension=".axd" kernelCachePolicy="CacheUntilChange" varyByHeaders="User-Agent" location="Client" /> </profiles> </caching> <httpProtocol allowKeepAlive="true"> <customHeaders> <add name="Cache-Control" value="public, max-age=31536000" /> </customHeaders> </httpProtocol> <validation validateIntegratedModeConfiguration="false" /> <modules runAllManagedModulesForAllRequests="true"> <remove name="RadUploadModule" /> <remove name="RadCompression" /> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" preCondition="integratedMode" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" preCondition="integratedMode" /> </modules> <handlers> <remove name="ChartImage_axd" /> <remove name="Telerik_Web_UI_SpellCheckHandler_axd" /> <remove name="Telerik_Web_UI_DialogHandler_aspx" /> <remove name="Telerik_RadUploadProgressHandler_ashx" /> <remove name="Telerik_Web_UI_WebResource_axd" /> <add name="ChartImage_axd" path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_SpellCheckHandler_axd" path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_DialogHandler_aspx" path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_RadUploadProgressHandler_ashx" path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" preCondition="integratedMode" /> <add name="Telerik_Web_UI_WebResource_axd" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" preCondition="integratedMode" /> </handlers> <security> <requestFiltering> <requestLimits maxAllowedContentLength="10485760" /> </requestFiltering> </security> <staticContent> <clientCache cacheControlMode="UseExpires" httpExpires="Wed, 01 Jan 2020 00:00:00 GMT"/> </staticContent> </system.webServer> <appSettings /> <system.web> <compilation debug="false" targetFramework="4.0" /> <pages> <controls> <add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI" /> </controls> </pages> <httpHandlers> <add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false" /> <add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false" /> <add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false" /> </httpHandlers> <httpModules> <add name="RadUploadModule" type="Telerik.Web.UI.RadUploadHttpModule" /> <add name="RadCompression" type="Telerik.Web.UI.RadCompression" /> </httpModules> <httpRuntime maxRequestLength="10240" /> </system.web> </configuration> and this is the resulting response header for http://cdn.test.dev/css/global.css: Cache-Control: private,public, max-age=31536000 Content-Type: text/css Content-Encoding: gzip Expires: Wed, 01 Jan 2020 00:00:00 GMT Last-Modified: Mon, 06 Sep 2010 08:53:06 GMT Accept-Ranges: bytes Etag: "0454eca04dcb1:0" Vary: Accept-Encoding Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 06 Sep 2010 14:57:08 GMT Content-Length: 4495

• Windows 7 Wireless Network Adapter Stopped Working

  - by Andrew B Schultz

  I have a Windows 7 Ultimate machine where the wireless adapter all of a sudden started having trouble connecting to wireless networks. Whenever I go to a new place and try to connect to a wireless network, it says that the DNS server is not responding, and tells me to go unplug the router and try again. After several locations in a row telling me this, I began to realize something was wrong with my adapter, not the routers. I am no longer asked to identify the security level for any new networks (Work, Home, or Public) like I used to be (it defaults to Public now - with the park bench icon). Often, resetting the router doesn't even work. Running the Windows 7 troubleshooter doesn't give me anything better than the advice to reset the router. However, the adapter will still connect to the wireless network at my main office without any problems. Does anyone know why a wireless network adapter can get so finicky so suddenly? Thanks!

• Simulating mouse clicks on Mac OS X does not work for some applications.

  - by Thomi

  I'm writing an application for Mac OS X 10.6 and later in C++. One part of the application needs to simulate mouse movement and mouse clicks. I do this currently by posting CGEvent objects using CGEventPost(kCGHIDEventTap, event);. This works, for the most part - I can simulate mouse movement and clicks just fine, but it seems to fail in some areas. For example: In Mozilla Firefox and Safari, I can click on all the menus, but cannot click on a link within a website. When I try, the link is highlighted, but the browser never follows the link. However, I can right-click on a link, select "open link in new tab", and everything works as expected. Solved - creating the mouse event using CGEventCreateMouseEvent(...) makes the event work within web browser. I can click on the "Dashboard" icon to brink up the dashboard, but I cannot click on the "i" button on any of the dashboard widgets. Similarly, clicking on any of the search results from the spotlight search widget doesn't work either. This inconsistency is along application boundaries. What might be the cause?

• Which software for intranet CMS - Django or Joomla?

  - by zalun

  In my company we are thinking of moving from wiki style intranet to a more bespoke CMS solution. Natural choice would be Joomla, but we have a specific architecture. There is a few hundred people who will use the system. System should be self explainable (easier than wiki). We use a lot of tools web, applications and integrated within 3rd party software. The superior element which is a glue for all of them is API. In example for the intranet tools we do use Django, but it's used without ORM, kind of limited to templates and url - every application has an adequate methods within our API. We do not use the Django admin interface, because it is hardly dependent on ORM. Because of that Joomla may be hard to integrate. Every employee should be able to edit most of the pages, authentication and privileges have to be managed by our API. How hard is it to plug Joomla to use a different authentication process? (extension only - no hacks) If one knows Django better than Joomla, should Django be used?

• C# internal VS VBNET Friend

  - by Will Marcouiller

  To this SO question: What is the C# equivalent of friend?, I would personally have answered "internal", just like Ja did among the answers! However, Jon Skeet says that there is no direct equivalence of VB Friend in C#. If Jon Skeet says so, I won't be the one telling otherwise! ;P I'm wondering how can the keyword internal (C#) not be the equivalent of Friend (VBNET) when their respective definitions are: Friend VBNET The Friend (Visual Basic) keyword in the declaration statement specifies that the elements can be accessed from within the same assembly, but not from outside the assembly. [...] internal C# Internal: Access is limited to the current assembly. To my understanding, these definitions mean quite the same to me. Then, respectively, when I'm coding in VB.NET, I use the Friend keyword to specify that a class or a property shall be accessible only within the assembly where it is declared. The same in C#, I use the internal keyword to specify the same. Am I doing something or anything wrong from this perspective? What are the refinements I don't get? Might someone please explain how or in what Friend and internal are not direct equivalences? Thanks in advance for any of your answers!

• Suggestions on implementing an iPad magazine app

  - by alku83

  I've been tasked with creating a magazine style app for iPad. Ideally it would look a little something like the Zinio app: http://www.zinio.com/ipad/ . This app is effectively a shell, allowing you to sample magazines (eg. read the first few pages) and select them for download. The magazines appear to have some sort of overlay, allowing you to interact with some things (eg. tap to watch a video). A few questions that come to mind: How would I go about delivering content to the user? In-app purchases aren't really an option, as some content will need to be delivered for free. Is it possible to download a package and make this available within the application? What format would be suitable for displaying the magazine? Sequential images, PDF, ebook? I'll need to have some form of interactivity. I guess I could have some form of lookup table, which would include information such as if the user taps on this page, within these coordinates, then launch this item. Anyone dealt with any similar issues?

• Why do all my browsers default to the "Impact" font?

  - by J Alain Ferry

  I've been struggling with a font issue which I hope you can help resolve. A few weeks ago I started seeing "Impact" as the default font on lots of webpages, rendering much of the content illegible. I think this issue began after I installed other fonts, but I'm not sure. The issue occurs on Chrome, IE and Firefox which suggests it is a Windows issue. By the time I tried to revert the changes via System Restore, it was too late. I tried to reset the default font but Windows does not seem to respond to that. When I click "Restore to default font settings" the button greys out but nothing else happens. No dialog box and no change in the issue. I've tried deleting the fonts in my font folder and re-installing them (from backup) but that did not work either. I inititially documented the issue here: http://forums.techguy.org/windows-7/1020796-help-weird-font-all-browsers.html Any ideas? Thanks!
