• proftpd, dynamic IP, and filezilla: port troubles

  - by Yami

  The basic setup: Two computers, one running proftpd, one attempting to connect via filezilla. Both linux (xubuntu on the server, kubuntu on the client). Both are at the moment behind a router on a residential (read: dynamic IP) connection; the client is a laptop I plan to take away from the home network, so I'll need this to work externally. I have my router set up to allow specific ports forwarded to each machine and, where possible, have plugged in those numbers into proftpd (via gadmin, double-checking the config file) and filezilla. Attempting to connect via active mode using the internal IP works: Status: Connecting to 192.168.1.139:8085... Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER <redacted> Response: 331 Password required for <redacted> Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PORT 192,168,1,52,153,140 Response: 200 PORT command successful Command: LIST Response: 150 Opening ASCII mode data connection for file list Response: 226 Transfer complete Status: Directory listing successful Attempting to connect via the domain name, however, leads to issues; in active mode, the PORT is the last command to be received according to the server's logs, and in passive mode, it's the PASV command. This leads me to believe I'm being redirected to a bad port? Active Sample: Status: Resolving address of <url> Status: Connecting to <ip:port> Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER <redacted> Response: 331 Password required for <redacted> Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PORT 174,111,127,27,153,139 Response: 200 PORT command successful Command: LIST Error: Connection timed out Error: Failed to retrieve directory listing Passive sample: Status: Resolving address of ftp.bonsaiwebdesigns.com Status: Connecting to 174.111.127.27:8085... Status: Connection established, waiting for welcome message... Response: 220 Crossroads FTP Command: USER yamikuronue Response: 331 Password required for yamikuronue Command: PASS ******* Response: 230 Anonymous access granted, restrictions apply Command: OPTS UTF8 ON Response: 200 UTF8 set to on Status: Connected Status: Retrieving directory listing... Command: PWD Response: 257 "/" is the current directory Command: TYPE I Response: 200 Type set to I Command: PASV Response: 227 Entering Passive Mode (64,95,64,197,101,88). Command: LIST Error: Connection timed out Error: Failed to retrieve directory listing In both cases, the log file ends at "PORT" or "PASV" - there's no record of ever receiving a "LIST" command. Just above that I can see the attempt to connect actively via the internal IP, which does indeed include a LIST command. My config file includes "PassivePorts 20001-26999", which are the port forwards I set up for the ftp server, and "Port 8085", which is also forwarded to the same machine. I also have a MasqueradeAddress set up to prevent it from reporting its internal IP, which was an earlier issue I had. I think what I'm asking is, is there another setting someplace I have to change to get this setup to work?

• Uncovering Compiler Errors in ASP.NET MVC Views

  - by Ben Griswold

  ASPX and ASCX files are compiled on the fly when they are requested on the web server. This means it’s possible that you aren’t catching compile errors associated with your views when you build your ASP.NET MVC project in Visual Studio.  Unless you’re willing to click through your entire application, rendering each view looking for errors, you application is left a little vulnerable to user issues.  Fortunately, there’s a work around.  Open up your MVC project file in notepad or within the Visual Studio IDE by unloading the project and then editing the .csproj file (both actions are available by right-clicking on the Project Node in Solution Explorer.)  Notice the MvcBuildViews option.  It’s probably set to false.  Flip the value to true and you’ll magically start compiling your views when you build your application. <MvcBuildViews>false</MvcBuildViews> Taking this action will slow down your builds a bit, but if you’re a hack like me, it’ll probably save your day in the long run. Now you’re probably thinking, “Neat trick – how’s it work?”  Scroll down toward the bottom of your csproj file and you will notice the AfterBuild target triggers the AspNetCompiler action if the MvcBuildViews option is set to true.  <Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Great. One more thing. Let’s say you don’t want to slow down all of your builds, but you absolutely want to know if there are any compiler issues with your views before you commit your code to version control or deploy or whatever.  Here’s what you can do – change the AfterBuild condition to run if your configuration is set to Release mode.  <Target Name="AfterBuild" Condition="'$(Configuration)'=='Release'">   <!– Always pre-compile ASPX and ASCX in release mode –>   <AspNetCompiler VirtualPath="temp"                   PhysicalPath="$(ProjectDir)\..\$(ProjectName)" /> </Target> Now your debug mode builds will continue to be as fast as ever and you can quickly validate your views by building in release mode when you so choose.  There’s one little catch – this setup won’t consider the MvcBuildViews option whatsoever! So if you decide to go with this configuration, you might want to add a comment near the MvcBuildViews option letting other developers know they can change the MvcBuildViews option as much as they’d like but it’s not going to affect the AfterBuild action.  Or don’t include the comment and let your team members figure it out for themselves…

• IPS Facets and Info files

  - by mkupfer

  One of the unusual things about IPS is its "facet" feature. For example, if you're a developer using the foo library, you don't install a libfoo-dev package to get the header files. Intead, you install the libfoo package, and your facet.devel setting controls whether you get header files. I was reminded of this recently when I tried to look at some documentation for Emacs Org mode. I was surprised when Emacs's Info browser said it couldn't find the top-level Info directory. I poked around in /usr/share but couldn't find any info files. $ ls -l /usr/share/info ls: cannot access /usr/share/info: No such file or directory Was I was missing a package? $ pkg list -a | egrep "info|emacs" editor/gnu-emacs 23.1-0.175.0.0.0.2.537 i-- editor/gnu-emacs/gnu-emacs-gtk 23.1-0.175.0.0.0.2.537 i-- editor/gnu-emacs/gnu-emacs-lisp 23.1-0.175.0.0.0.2.537 --- editor/gnu-emacs/gnu-emacs-no-x11 23.1-0.175.0.0.0.2.537 --- editor/gnu-emacs/gnu-emacs-x11 23.1-0.175.0.0.0.2.537 i-- system/data/terminfo 0.5.11-0.175.0.0.0.2.1 i-- system/data/terminfo/terminfo-core 0.5.11-0.175.0.0.0.2.1 i-- text/texinfo 4.7-0.175.0.0.0.2.537 i-- x11/diagnostic/x11-info-clients 7.6-0.175.0.0.0.0.1215 i-- $ Hmm. I didn't have the gnu-emacs-lisp package. That seemed an unlikely place to stick the Info files, and pkg(1) confirmed that the info files were not there: $ pkg contents -r gnu-emacs-lisp | grep info usr/share/emacs/23.1/lisp/info-look.el.gz usr/share/emacs/23.1/lisp/info-xref.el.gz usr/share/emacs/23.1/lisp/info.el.gz usr/share/emacs/23.1/lisp/informat.el.gz usr/share/emacs/23.1/lisp/org/org-info.el.gz usr/share/emacs/23.1/lisp/org/org-jsinfo.el.gz usr/share/emacs/23.1/lisp/pcvs-info.el.gz usr/share/emacs/23.1/lisp/textmodes/makeinfo.el.gz usr/share/emacs/23.1/lisp/textmodes/texinfo.el.gz $ Well, if I have what look like the right packages but don't have the right files, the next thing to check are the facets. The first check is whether there is a facet associated with the Info files: $ pkg contents -m gnu-emacs | grep usr/share/info dir facet.doc.info=true group=bin mode=0755 owner=root path=usr/share/info file [...] chash=[...] facet.doc.info=true group=bin mode=0444 owner=root path=usr/share/info/mh-e-1 [...] file [...] chash=[...] facet.doc.info=true group=bin mode=0444 owner=root path=usr/share/info/mh-e-2 [...] [...] Yes, they're associated with facet.doc.info. Now let's look at the facet settings on my desktop: $ pkg facet FACETS VALUE facet.locale.en* True facet.locale* False facet.doc.man True facet.doc* False $ Oops. I've got man pages and various English documentation files, but not the Info files. Let's fix that: # pkg change-facet facet.doc.info=True Packages to update: 970 Variants/Facets to change: 1 Create boot environment: No Create backup boot environment: Yes Services to change: 1 DOWNLOAD PKGS FILES XFER (MB) Completed 970/970 181/181 9.2/9.2 PHASE ACTIONS Install Phase 226/226 PHASE ITEMS Image State Update Phase 2/2 PHASE ITEMS Reading Existing Index 8/8 Indexing Packages 970/970 # Now we have the info files: $ ls -F /usr/share/info a2ps.info dir@ flex.info groff-2 regex.info aalib.info dired-x flex.info-1 groff-3 remember ...

• Install GIMP 2.7.1 on Lucid Lynx using PPA

  - by Vivek

  GIMP lovers are going to be disappointed to hear that GIMP is going away in the next release of much awaited Ubuntu 10.04. Today we take a look at installing in on Lucid Lynx using PPA. The reason for getting rid of it as cited by the GIMP developers, is that GIMP is too professional a software to be included in regular desktop version of Ubuntu. And it takes up too much of space on the disk. Also, the fact that it’s too complicated for regular users. If you can’t live without it…let’s see how to install GIMP 2.7.1 on Lucid Lynx (Currently in Alpha). The new version of GIMP supports single window mode and we will also see how to enable this feature as well. First we need to add the official GIMP 2.7.1 PPA in the software sources of Ubuntu 10.04, by opening the terminal window and typing the following command: sudo sh -c “echo ‘deb http://ppa.launchpad.net/matthaeus123/mrw-gimp-svn/ubuntu lucid main’ >> /etc/apt/sources.list” Now that we have added the PPA we need to add the GPG key, so type the following in your Terminal window. sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 405A15CB Next up we have to update the software repository… sudo apt-get update All that is left is to install GIMP 2.7.1 by typing in the following… sudo apt-get install gimp Click ‘Y’ (for yes) to install GIMP Once GIMP is installed you can start it by going to Applications > Graphics > GNU Image Manipulation Program. You now have your favorite GIMP on your favorite Ubuntu 10.04. As you can see in the image below, GIMP still comes with default 3 windows, which could clog up your lower panel In Ubuntu 10.04. However, now you can run GIMP in single window mode by going to Windows > Single-Window mode. That’s all! Now you have your GIMP running in single window mode with less of hassle to manage 3 windows. It’s unfortunate that GIMP will not be included, but by following these instructions, you’ll be able to enjoy using it in Ubuntu 10.04.

• Secret Agent Man

  - by Bil Simser

  Just a quick one this morning as we all get started in the week. Something that comes into play (sometimes in a big way) is the user agent string your browser gives off. So for example using the User-Agent field in the request header, you can determine what browser the user is running and act accordingly.Internet Explorer 9 modified the UA string slightly so just in case you're looking for it here are the user agent strings for IE9 (in various modes):Internet Explorer 9 Mode: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)Internet Explorer 8 Mode: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MS-RTC LM 8; InfoPath.3; .NET4.0C; .NET4.0E; Zune 4.7)Internet Explorer 7 Mode: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MS-RTC LM 8; InfoPath.3; .NET4.0C; .NET4.0E; Zune 4.7)Internet Explorer 9 (Compatibility Mode): Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; MS-RTC LM 8; InfoPath.3; .NET4.0C; .NET4.0E; Zune 4.7)A couple of things to note here:This was from a 64-bit Windows 7 client so that might account for the WOW64 in the agent string (I don't have a 32-bit client to test from)Various applications and platforms add to the UA string just like they do in previous IE releases. So for example you can see I have various .NET versions installed as well as Zune. You can take advantage of this by querying the UA string for compatibilities and present options accordingly to the end user.As applications will continue to add and modify this string you'll want to query the string for parts not the entire string. For example if you want to detect if you're coming from IE running  on a Windows Phone 7 just look for "iemobile" in the user agent stringHappy hacking!

• Rotating text using CSS

  - by Renso

  Normal 0 false false false EN-US X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Goal: Rotating text using css only. How: Surprisingly IE supports this feature rather well. You could use property filters in IE, but since this is only supported on IE browsers, I would not recommend it. CSS3, still in proposal state, has a "writing-mode" property for doing this. It has been part of IE's browser engine since IE5.5. Now that it is part of the CSS3 draft specification, would be the best way to implement this going forward. Webkit based browsers; Firefox 3.5+, Opera 11 and IE9 implement this feature differently by utilizing the transform property. Without using third-party JavaScript or CSS properties, we can use the CSS3 "writing-mode" property, supported from IE5.5 up to IE8, the latter adding addition formatting options through -ms extensions. <style type="text/css"> .rightToLeft{ writing-mode: tb-rl; } </style> <p class="rightToLeft">This is my text</p> This will rotate the text 90 degrees, starting from the right to the left. Here are all the options: ·         lr-tb – Default value, left to right, top to bottom ·         rl-tb – Right to left, top to bottom ·         tb-rl – Vertically; top to bottom, right to left ·         bt-rl – Vertically; bottom to top, right to left ·         tb-lr – Available in IE8+: -ms-writing-mode; top to bottom, left to right ·         bt-lr – Bottom to top, left to right ·         lr-bt – Left to right, bottom to top What about Firefox, Safari, etc.? The following techniques need to be used on Webkit browsers like Firefox, Opera 11, Google Chrome and IE9. These browsers require their proprietary vendor extensions: -moz-, -webkit-, -o- and -ms-. -webkit-transform: rotate(90deg);    -moz-transform: rotate(90deg); -ms-transform: rotate(90deg); -o-transform: rotate(90deg); transform: rotate(90deg);

• Rotating WebLogic Server logs to avoid large files using WLST.

  - by adejuanc

  By default, when WebLogic Server instances are started in development mode, the server automatically renames (rotates) its local server log file as SERVER_NAME.log.n.  For the remainder of the server session, log messages accumulate in SERVER_NAME.log until the file grows to a size of 500 kilobytes.Each time the server log file reaches this size, the server renames the log file and creates a new SERVER_NAME.log to store new messages. By default, the rotated log files are numbered in order of creation filenamennnnn, where filename is the name configured for the log file. You can configure a server instance to include a time and date stamp in the file name of rotated log files; for example, server-name-%yyyy%-%mm%-%dd%-%hh%-%mm%.log.By default, when server instances are started in production mode, the server rotates its server log file whenever the file grows to 5000 kilobytes in size. It does not rotate the local server log file when the server is started. For more information about changing the mode in which a server starts, see Change to production mode in the Administration Console Online Help.You can change these default settings for log file rotation. For example, you can change the file size at which the server rotates the log file or you can configure a server to rotate log files based on a time interval. You can also specify the maximum number of rotated files that can accumulate. After the number of log files reaches this number, subsequent file rotations delete the oldest log file and create a new log file with the latest suffix.  Note: WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth. To Rotate via WLST : #invoke WLSTC:\>java weblogic.WLST#connect WLST to an Administration Serverawls:/offline> connect('username','password')#navigate to the ServerRuntime MBean hierarchywls:/mydomain/serverConfig> serverRuntime()wls:/mydomain/serverRuntime>ls()#navigate to the server LogRuntimeMBeanwls:/mydomain/serverRuntime> cd('LogRuntime/myserver')wls:/mydomain/serverRuntime/LogRuntime/myserver> ls()-r-- Name myserver-r-- Type LogRuntime-r-x forceLogRotation java.lang.Void :#force the immediate rotation of the server log filewls:/mydomain/serverRuntime/LogRuntime/myserver> cmo.forceLogRotation()wls:/mydomain/serverRuntime/LogRuntime/myserver> The server immediately rotates the file and prints the following message: <Mar 2, 2012 3:23:01 PM EST> <Info> <Log Management> <BEA-170017> <The log file C:\diablodomain\servers\myserver\logs\myserver.log will be rotated.

• Video works with 'Try me' but not after install. What is the difference? U12.04LTS,

  - by HarveyP

  My hard drive got corrupted so I did a reinstall. Tested Youtube in FF during 'try me' and it worked - jerky, but it worked. Instal without all the updates (576 outstanding now) in order to get ff installed as per the demo - to no avail. In 'try me' mode ff NEVER crashed! After install ff crashed whilst I was typing in 'youtube' in the address field. When I finally got to youtube - no video. What is the difference between ff in try me and ff after install? Off to try some selected updates now to see if I can see it for myself. In previous installation I had several profiles and aliased ff with -safe-mode switch to simplify startup of most stable ff. Also found that ff startup in graphic mode worked better (but still without video) with all of the extensions disabled and all of the plugins set to "ask" and always denied ... I have SiS graphic card in SiS Motherboard for XP and ancient Hyundai ImageQuest QV770 monitor. I have Ubuntu 12.04.01 LTS 1 day after install with only the immediate upgrades requested to language pack (English UK). Using FR Alternative keyboard. Connected with domestic wifi network from Orange (FT) I really want to use Skype, but won't bother installing it (again) without video as I can do my sms on FB - whilst ff is not crashed ... Update ... Is something overflowing? I have just had to reboot in order to get ff to restart in any way shape or form - restart on crash form generates new crash form, etc. It was however a good half hour before it crashed so some improvement over conditions before disk corruption. I have now installed all of the critical updates (332 recommended updates still outstanding) which included some relating to ff. Still no video. Still crashing - especially when on Grepolis website. Since the re-install I have had a lovely 1024x768 screen, but after last ff crash and reboot I got a message about 'low graphics mode' and 'setting things myself'. I was not sufficiently tuned in at the time to take proper note - I have no doubt I shall see it again and shall report accordingly. I still have only laptop options for my screen and do not know how to rectify this. Spent a few days with ubuntu on a different, newer machine which has now suffered a graphics breakdown. Returned to this old one again, but with new flat screen Monitor. Found SIS drivers for my graphics BUT it is intended for Red Hat 7.2. I chose this over the version for 7.0 because I thought what the hell, I might not be able to do anything with either of them but this is the later one ... The file will not open with software manager - found a similar problem on Overclock but it has not helped me to install this driver. File name is sis_drv.o-410 and it is currently idling away in my Downloads folder ... I have tried the solution offered on another sis problem, but this shows that my xserver-xorg-video-sis driver is up to date. I am now at a loss as to how to proceed if I can't install the latest sis driver from sis ... Does nobody know how FF changes from "try-me" to "installed"? Any time I MUST have video I reboot from the disk again, but this is tedious! Also one of the things I mock most about MS is the constant rebooting ... UPDATE 10/6/2014 I have installed chromium-browser - worse, crashes even more often than ff.I have installed epiphany - better; Video works but not the associated soundtrack.FireFox is version 14.01 in 'try me' and version 29.0 from my install. Would it be useful to try to downgrade FireFox in order to get video?

• Problem displaying custom error page in ASP.NET MVC 2

  - by robert_d

  This is customErrors section from my web.config file <customErrors mode="On"> <error statusCode="500" redirect="HTTP500.aspx" /> </customErrors> HTTP500.aspx is the same as standard /Views/Shared/Error.aspx page. When I get HTTP 500 error I see this page: Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed. Details: To enable the details of this specific error message to be viewable on the local server machine, 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 "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" 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. But when I change the above customErrors section like this: <customErrors mode="On"> <error statusCode="500" redirect="HTTP500.htm" /> </customErrors> then HTTP500.htm page is displayed when HTTP 500 error occurs. Why HTTP500.aspx page isn't displayed?

• Silverlight nested RadGridView SelectedItem DataContext

  - by Ciaran

  Hi, I'm developing a Silverlight 4 app and am using the 2010 Q1 release 1 RadGridView. I'm developing this app using the MVVM pattern and trying to keep my codebehind to a minimum. On my View I have a RadGridView and this binds to a property on my ViewModel. I am setting a property via the SelectedItem. I have a nested RadGridView and I want to set a property on my ViewModel to the SelectedItem but I cannot. I think the DataContext of my nested grid is the element in the parent's bound collection, rather than my ViewModel. I can easily use codebehind to set my ViewModel property from the SelectionChanged event on the nested grid, but I'd rather not do this. I have tried to use my viewModelName in the ElementName in my nested grid to specify that for SelectedItem, the ViewModel is the DataContext, but I cannot get this to work. Any ideas? Here is my Xaml: <grid:RadGridView x:Name="master" ItemsSource="{Binding EntityClassList, Mode=TwoWay}" SelectedItem="{Binding SelectedEntityClass, Mode=TwoWay}" AutoGenerateColumns="False" > <grid:RadGridView.Columns> <grid:GridViewSelectColumn></grid:GridViewSelectColumn> <grid:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description"/. </grid:RadGridView.Columns> <grid:RadGridView.RowDetailsTemplate> <DataTemplate> <grid:RadGridView x:Name="child" ItemsSource="{Binding EntityDetails, Mode=TwoWay}" SelectedItem="{Binding DataContext.SelectedEntityDetail, ElementName='RequestView', Mode=TwoWay}" AutoGenerateColumns="False" > <grid:RadGridView.Columns> <grid:GridViewSelectColumn></grid:GridViewSelectColumn> <grid:GridViewDataColumn DataMemberBinding="{Binding ServiceItem}" Header="Service Item" /> <grid:GridViewDataColumn DataMemberBinding="{Binding Comment}" Header="Comments" /> </grid:RadGridView.Columns> </grid:RadGridView> </DataTemplate> </grid:RadGridView.RowDetailsTemplate> </grid:RadGridView>

Also, when I click on second row, firstly first row fires the event and then the second row fires it and shows the nested grid. Please help.

• How can I sort a DataGridTemplateColumn on a WPF Toolkit DataGrid?

  - by Kilhoffer

  I have a WPF Toolkit DataGrid with one DataGridTemplateColumn. I've specified in a grid attribute that I wish all columns to be sortable, but the DataGridTemplateColumn won't allow it. All other columns do allow sorting. I've even tried explicitly setting CanUserSort to true for that column, but no luck. Is it even possible to sort a template column? I've provided a custom sorter that works for all columns, but the header won't allow a sort click. <Controls:DataGrid ItemsSource="{Binding Events}" AutoGenerateColumns="False" CanUserSortColumns="True" CanUserReorderColumns="False" Sorting="DataGrid_Sorting" x:Name="EventsGrid"> <Controls:DataGrid.Columns> <Controls:DataGridTemplateColumn Header="Type" Width="42" CanUserResize="False"> <Controls:DataGridTemplateColumn.CellTemplate> <DataTemplate> <Image Source="{Binding EventTypeImage, Mode=OneWay}" HorizontalAlignment="Center" Width="16"/> </DataTemplate> </Controls:DataGridTemplateColumn.CellTemplate> </Controls:DataGridTemplateColumn> <Controls:DataGridTextColumn Header="Source" Binding="{Binding Source, Mode=OneWay}" /> <Controls:DataGridTextColumn Header="Details" MinWidth="175" Binding="{Binding Details, Mode=OneWay}" /> <Controls:DataGridTextColumn Header="Timestamp" MinWidth="175" Binding="{Binding Timestamp, Mode=OneWay}" IsReadOnly="True"/> </Controls:DataGrid.Columns> </Controls:DataGrid>

• Using UIScreen to drive a VGA display - doesn't seem to show the UIWindow?

  - by Peter Hajas

  HI there, I'm trying to use UIScreen to drive a separate screen with the VGA dongle on my iPad. Here's what I've got in my root view controller's viewDidLoad: //Code to detect if an external display is connected to the iPad. NSLog(@"Number of screens: %d", [[UIScreen screens]count]); //Now, if there's an external screen, we need to find its modes, itereate through them and find the highest one. Once we have that mode, break out, and set the UIWindow. if([[UIScreen screens]count] > 1) //if there are more than 1 screens connected to the device { CGSize max; UIScreenMode *maxScreenMode; for(int i = 0; i < [[[[UIScreen screens] objectAtIndex:1] availableModes]count]; i++) { UIScreenMode *current = [[[[UIScreen screens]objectAtIndex:1]availableModes]objectAtIndex:i]; if(current.size.width > max.width); { max = current.size; maxScreenMode = current; } } //Now we have the highest mode. Turn the external display to use that mode. UIScreen *external = [[UIScreen screens] objectAtIndex:1]; external.currentMode = maxScreenMode; //Boom! Now the external display is set to the proper mode. We need to now set the screen of a new UIWindow to the external screen external_disp = [externalDisplay alloc]; external_disp.drawImage = drawViewController.drawImage; UIWindow *newwindow = [UIWindow alloc]; [newwindow addSubview:external_disp.view]; newwindow.screen = external; }

• Making Vim ubiquitous?

  - by Hamish Downer

  The Pragmatic Programmer recommends that you should use one text editor for everything. My chosen weapon editor is Vim. So I want to collect all the ways in which Vim (and the Vim keybindings) can be used and setting up your computer to make Vim work well. This includes how to embed Vim in your IDE, web browser, email client, command shell ... But I don't want Vim tips - there are other questions for them. I want tips to get into Vim, or Vim mode. Though tips about Vim mode not in an editor would be allowed (e.g. tips for vi mode when using Bash). Update: Going quite well so far, with ways to edit in Vim/gVim, or to get vi mode in Firefox, Safari, Thunderbird, many IDEs and command line applications, MS Outlook and Word. But I'm wondering if there are more. Particular applications I wonder about include OpenOffice.org KOffice Kmail Evolution Internet Explorer GIMP and Photoshop ... (only joking ;)

• .NET Fingerprint SDK

  - by Kishore A

  I am looking for a comparison of Fingerprint reader SDKs available for .NET (we are using .Net 3.5). My requirements are 1. Associate more than one fingerprint with a person. 2. Store the fingerprints it self. (So I do not have to change the Database for my program.) 3. Work in both event and no-event mode. (Event Mode: Give notification if someone swipes a finger on the reader; No-Event mode: I activate the reader in synchronous mode). 4. Should provide API for either confirming a user or Identifying a user. (Confirm API: I send the person's ID/unique number and it confirms that it is the same person; Identifying API: The sdk sends the person's ID after it looks up the person using the fingerprint) I would also like to get a comparison of Fingerprint readers if anybody knows of one available on the internet. Hope I was clear. Thanks, Kishore.

• iPhone Safari does not auto scale back down on portrait->landscape->portrait

  - by Tom

  Hi, I have a very simple HTML page with this META tag for the iPhone: <meta name="viewport" content="height=device-height,width=device-width,initial-scale=1.0,user-scalable=no" /> When the page loads in portrait mode it looks fine and the width fits the screen. When I rotate the iPhone to landscape mode the web page is auto resized to fit the landscape width. Good, this is what I want. But when I rotate back to landscape, the page is not resized back to fit the portrait width like it was before. It remains in the landscape width. I want the iPhone to set it back to the right width automatically, just like it did for the landscape mode. I don't think this should involve orientation listeners because it is all done automatically and I don't have any special styling for the different modes. Why doesn't the iPhone resize the web page back in portrait mode? How do I fix this? Thanks! Tom.

• Custom Installer class , rollback method never called.

  - by yossi1981

  Hi guys. I am having an installer class , Here is a snippet: [RunInstaller(true)] public partial class ServerWrapInstaller : Installer { public override void Install(IDictionary stateSaver) { EventLog.WriteEntry("Installer", "Install", EventLogEntryType.Information); base.Install(stateSaver); } public override void Commit(IDictionary savedState) { EventLog.WriteEntry("Installer", "Commit", EventLogEntryType.Information); base.Commit(savedState); } public override void Rollback(IDictionary savedState) { EventLog.WriteEntry("Installer", "Rollback", EventLogEntryType.Information); base.Rollback(savedState); } public override void Uninstall(IDictionary savedState) { EventLog.WriteEntry("Installer", "UnInstall", EventLogEntryType.Information); base.Uninstall(savedState); } } Now i start the installation in full GUI mode and then click the "Cancel" button in the middle of the process causing the installation to roll back. The problem is that the RollBack method is not called. I don't see the expected entry in the event log. I want to mention that if i let the installation to complete , I do see the "Install" message in the event log and If i then uninstall , I see the "uninstall" message in the event log. But if stop the installtion process in the middle , by pressing the "cancel" button , I do see the progress bar going backward , but the rollback method is not called. what am I doing wrong ? thanks in advance for any help. Edit: Providing more details... The installer is an MSI package. The package is built in vs2009 using a setup project. The installer class is used as a custom action by the setup project. Since this is a MSI Package I have an option to run it in silent mode or in user-interactive more . When I wrote "Full GUI mode" , I ment User-Interactive mode.

• How do I handle nils in views?

  - by Badweather

  I have the following models set up: class Contact < ActiveRecord::Base belongs_to :band belongs_to :mode validates_presence_of :call, :mode validates_associated :mode, :band validates_presence_of :band, :if => :no_freq? validates_presence_of :freq, :if => :no_band? protected def no_freq? freq.nil? end def no_band? band.nil? end end class Band < ActiveRecord::Base has_many :logs end class Mode < ActiveRecord::Base has_many :logs end When I enter a frequency on my new view it allows for no band to be specified if a freq is entered. This creates a problem in my other views though because band is now nil. How do I allow for band not to be specified and just show up as empty on my index and show views, and then in the edit view allow one to be specified at a later point in time. I have been able to get my index to display a blank by doing: contact.band && contact.band.name But I'm not sure if this is a best approach, and I'm unsure of how to apply a similar solution to my other views.

• How to perform two-way data binding of controls in a user control inside a FormView

  - by Sandor Drieënhuizen

  I'm trying to perform two-way data binding on the controls in my user control, which is hosted inside a FormView template. FormView: <asp:ObjectDataSource runat="server" ID="ObjectDataSource" TypeName="WebApplication1.Data" SelectMethod="GetItem" UpdateMethod="UpdateItem"> </asp:ObjectDataSource> <asp:FormView runat="server" ID="FormView" DataSourceID="ObjectDataSource"> <ItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </ItemTemplate> <EditItemTemplate> <uc:WebUserControl1 runat="server"></uc:WebUserControl1> </EditItemTemplate> </asp:FormView> User control: <%@ Control Language="C#" ... %> <asp:TextBox runat="server" ID="TitleTextBox" Text='<%# Bind("Title") %>'> </asp:TextBox> The binding works fine when the FormView is in View mode but when I switch to Edit mode, upon calling UpdateItem on the FormView, the bindings are lost. I know this because the FormView tries to call an update method on the ObjectDataSource that does not have an argument called 'Title'. I tried to solve this by implementing IBindableTemplate to load the controls that are inside my user control, directly into the templates (just like I had entered them declaratively like in the code above). However, when calling UpdateItem in edit mode, the container that gets passed into the ExtractValues method of the template, does not contain the TextBox anymore. It did in view mode! I have found some questions on SO that relate to this problem but they are rather dated and they don't provide any answers that helped me solve this problem. How do you think I could solve this problem? It seems to be such a simple requirement but apparently it's more like opening a can of worms...

• Very strange jQuery / AJAX behavior

  - by Dr. DOT

  I have an Ajax call to the server that only works when I pass an alert(); to it. Cannot figure out what is wrong. Can anyone help? This Does Not Work (ie., Ajax call to server does not get made): <!-- jQuery.support.cors = true; // needed for ajax to work in certain older browsers and versions $('input[name="status"]').on("change", function() { if ($('input:radio[name="status"]:checked').val() == 'Y') { $.ajax({ url: 'http://mydomain.com/dir/myPHPscript.php?param=' + $('#param').val() + '&id=' + ( $('#id').val() * 1 ) + '&mode=' + $('#mode').val() }); } window.parent.closePP(); window.top.location.href = $('#redirect').val(); // reloads page }); //--> This Works! (ie., Ajax call to server gets made when I have the alert() present): <!-- jQuery.support.cors = true; // needed for ajax to work in certain older browsers and versions $('input[name="status"]').on("change", function() { if ($('input:radio[name="status"]:checked').val() == 'Y') { $.ajax({ url: 'http://mydomain.com/dir/myPHPscript.php?param=' + $('#param').val() + '&id=' + ( $('#id').val() * 1 ) + '&mode=' + $('#mode').val() }); **alert('this makes it work');** } window.parent.closePP(); window.top.location.href = $('#redirect').val(); // reloads page }); //--> Thanks.
