  • How to make a Windows Mobile based WinForms .Net application easily changeable?

    - by Arthur
    I need to build a Win Mobile WinForms .Net application that once developed will be easy to morph or adjust to new user requirements quickly (including changes in GUI). The main objective is to minimize the development time (development to production roll-out effort). Also, a nice thing to have is to be able to test it in an automated way. The application must be able to: 1) Persist state (may use a local database); 2) Sync data across (via Radio or WiFi); 3) Exchange info with a desktop PC or a central server;

  • How to dispatch a multimethod on the type of an array

    - by Arthur Ulfeldt
    I'm working on a multimethod that needs to update a hash for a bunch of different things in a sequence. Looked fairly straitforward until I tried to enter the 'type of an array of X'. (defmulti update-hash #(class %2)) (type (byte 1)) => java.lang.Byte (defmethod update-hash java.lang.Byte [md byte] (. md update byte)) (type (into-array [ (byte 1)])) => [Ljava.lang.Byte; (defmethod update-hash < WHAT GOES HERE > [md byte]

  • Stop MSVC++ debug errors from blocking the current process?

    - by Mike Arthur
    Any failed ASSERT statements on Windows cause the below debug message to appear and freeze the applications execution. I realise this is expected behaviour but it is running periodically on a headless machine so prevent the unit tests from failing, instead waiting on user input indefinitely. Is there s a registry key or compiler flag I can use to prevent this message box from requesting user input whilst still allowing the test to fail under ASSERT? Basically, I want to do this without modifying any code, just changing compiler or Windows options. Thanks!

  • What does the condition "new pull" mean?

    - by Nathan DeWitt
    I'm looking for a hard drive, and some of the conditions are listed as "New Pull" or "System Pull". I figure the System Pull means "taken from a computer and now sold separately" but what does New Pull mean? Does this mean it was assembled and never used? Or maybe it has been freshly pulled from a used machine?

  • Correct PHP5 DLL for Apache 2.2?

    - by Nathan Long
    I have installed Apache 2.2.14 (Win32) on a Windows XP machine and am trying to add the latest PHP module. I downloaded the ZIP file from here labeled "VC9 x86 Non Thread Safe" and extracted to my Apache directory. I then copied php5.dll to Apache's bin directory and copied php.ini to C:\Windows. In httpd.conf, I added these lines: LoadModule php5_module "C:/Program Files/Apache Software Foundation/Apache2.2/bin/php5.dll" AddType application/x-httpd-php .php Now Apache will not start. error.log says this: "Can't locate API module structure php5_module in file C:/Program Files/Apache Software Foundation/Apache2.2/bin/php5.dll": No error" I think I may have the wrong .dll file, because I found tutorials that use the filename php5apache2.dll and I didn't see that in the PHP package I got. Also, I have seen references to a file called php5ts.dll, but I don't see that either. What exactly do I need to make PHP5 work?

  • IIS7 Custom ASP.NET Errors

    - by Nathan Roe
    I'm trying to setup a custom error page for the IIS 7 404.13 (Content length too large) error. Here's the relevant sections of my web.config file: <system.webServer> <httpErrors errorMode="Custom" existingResponse="Replace"> <remove statusCode="404" subStatusCode="13" /> <error statusCode="404" subStatusCode="13" prefixLanguageFilePath="" path="/FileUpload/Test.aspx" responseMode="ExecuteURL" /> </httpErrors> <security> <requestFiltering> <requestLimits maxAllowedContentLength="10240" /> </requestFiltering> </security> </system.webServer> The response that is being sent back to the server is blank. The Test.aspx file is not blank. Any idea what's going on here?

  • 3GB RAM Installed and Detected by BIOS, Windows Vista 32bit Only Sees 2GB

    - by Nathan Taylor
    I am attempting to install more RAM on a Windows Vista 32bit machine which is using a X6DAL-XG motherboard and the RAM amount reported in the BIOS is 3GB+, but Windows is only reporting 2GB installed. The motherboard has 6 RAM bays which I have populated with various combinations of 4 1GB sticks, and 2 512mb sticks, but no matter how I configure them Windows doesn't see more than 2GB. I realize of course 32-bit Windows has a 3gb cap on memory, but that doesn't explain why it will only report 2GB when there are in fact (currently) 5GB installed. I should think I would be able to see at least 3GB. According to the spec list for the motherboard the minimum RAM requirements are DDR333/266mhz installed in pairs. I have done this exactly, and the BIOS isn't reporting any problems at POST. RAM Configuration (according to CPU-Z): Slot #1: Kingston 128mx72D266C25 - 1024mb PC2100 (133mhz) Slot #2: Kingston KVR266X72RC25/1024 - 1024mb PC2100 (133mhz) Slot #3: PQI - 512mb PC2700 (166mhz) Slot #4: Kingston 128mx72D266C25 - 1024mb PC2100 (133mhz) Slot #5: Kingston KVR266X72RC25/1024 - 1024mb PC2100 (133mhz) Slot #6: PQI - 512mb PC2700 (166mhz) I'm not sure if memory specs above conflict with this statement in the motherboard manual or not: Memory Support The X6DAL-XG supports up to 12GB/24GB of registered ECC DDR333/266 (PC2700/PC2100) memory. The motherboard was designed to support 4GB (PC2100) modules in each slot, but only the 2GB modules have been tested. When using registered ECC DDR333 (PC2700) memory, installing four pieces of double-banked memory or six pieces of single-banked memory is supported. So, am I doing something wrong with the RAM I have now, or is there some sort of compatibility problem which I am missing? Thanks!

  • Xen HVM networking wont work

    - by Nathan
    I'm trying to get a Xen HVM network working using route however I am failing. Xen PV works fine using Ubuntu but when installing Ubuntu on HVM it fails to pick up the network. I'll let you know now that I'm not that experienced with Xen so I would appreciate any help. vm104 is the HVM thats causing me the problems, here is the configs that I believe should help resolve the problem. [root@eros vm104]# cat vm104.cfg import os, re arch = os.uname()[4] if re.search('64', arch): arch_libdir = 'lib64' else: arch_libdir = 'lib' kernel = '/usr/lib/xen/boot/hvmloader' builder = 'hvm' memory = 6000 shadow_memory = '8' cpu_weight = 256 name = 'vm104' vif = ['type=ioemu, ip=85.25.x.y, vifname=vifvm104.0, mac=00:16:3e:52:3d:fe, bridge=xenbr0'] acpi = 1 apic = 1 vnc = 1 vcpus = 4 vncdisplay = 3 vncviewer = 0 vncconsole = 1 vnclisten = '217.118.x.y' vncpasswd = 'kCfb5S4tE7' serial = 'pty' disk = ['phy:/dev/vpsvg/vm104_img,hda,w', 'file:/home/solusvm/xen/iso/Windows-Server-2008-RC2.iso,hdc:cdrom,r'] device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm' boot = 'cd' sdl = '0' usbdevice = 'tablet' pae=1 [root@eros /]# cat /etc/xen/xend-config.sxp | egrep -v "(^#.*|^$)" (xend-unix-server yes) (xend-unix-path /var/lib/xend/xend-socket) (xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$') (network-script network-route) (vif-script vif-route) (network-script 'network-route netdev=eth0') (dom0-min-mem 256) (dom0-cpus 0) (vnc-listen '0.0.0.0') (vncpasswd '') (keymap 'en-us') The Windows install will not pick up the network - I've tried setting the IP manually by using the Xen servers IP as the gateway and setting the main IP in Windows but no luck. If anyone needs any more information let me know and I appreciate any input!

  • Triple boot WIndows 7, Windows 8, and Mountain Lion on Macbook Pro

    - by Nathan
    Ok, So I have a bit of a unique situation here I could use some help on. I've modded my summer 2011 MBPro to have 2 harddrives by replacing the optical drive. OSX Mountain Lion is installed on a single partition of a 120GB SSD. The second drive is 750GB, partitioned as 550GB, 150GB, and ~50GB. I've set the 550GB to act as my OSX homefolder, but I'd like to install windows 7 and Windows 8 on the remaining partitions. It Took a while, but by following this guide, I eventually found a way to install Windows without a CD/DVD drive by following this http://huguesval.com/blog/2012/02/installing-windows-7-on-a-mac-without-superdrive-with-virtualbox/ It worked flawlessly for creating both windows 7 and windows 8 images that I could clone onto FAT32 partitions. However, I have encountered a problem when trying to triple boot. After I put Windows 8 onto the ~50GB partition and tried to boot into windows 7 I get an error that says something like: error: 0x0000000e The Boot selection failed because the required device is inaccessible. If I re-clone the windows 7 image onto the drive and select the option to "replace BCD" file for the drive, windows 7 will boot but windows 8 now gives me the same exact error. I realize this is a pretty extensive setup, but if anyone has some insight I'd love to hear it.

  • Cannot install xdebug

    - by Nathan Mann
    I'm getting a large number of undefined references when using $ld xdebug.so I have added the "zend_extension="/bla/xdebug.so"" to the conf for apache and it is giving me a config test failed because it cannot find the file. The file has been chown'd to www-data, so I do not believe it is a permissions error. I have run the wizard at xdebug.org/wizard.php to make sure the version would be correct, I updated to the version it recommended with an install from source and still receive the same error with apache and same output from $ld. I originally installed xdebug with: $apt-get install php5-xdebug And have also tried with: $pecl install xdebug

  • Saving a modified InfoPath form to its form library

    - by Nathan Lykken
    Within our corporate SharePoint 2007 site, there is a particular form library that contains 10 separate files. 9 of these are either Excel, Word, or PowerPoint files and one of these is an InfoPath 2007 form that serves as a report. After noticing an error within this InfoPath form, I saved this InfoPath form to my local directory and then, within the design mode of InfoPath, I modified this InfoPath form. What is the proper way to save this modified InfoPath form to its form library? Everything that I have tried results in nobody except myself having access to this modified InfoPath form. I can open this InfoPath form without error but when my coworkers try to open this InfoPath form on their machines, they receive this error: “The form cannot be opened because it requires the domain permission level and it currently has restricted permission. To fix this problem, open the form from the location it was published to."

  • Which user account should be used for WSGIDaemonProcess?

    - by Nathan S
    I have some Django sites deployed using Apache2 and mod_wsgi. When configuring the WSGIDaemonProcess directive, most tutorials (including the official documentation) suggest running the WSGI process as the user in whose home directory the code resides. For example: WSGIScriptAlias / /home/joe/sites/example.com/mod_wsgi-handler.wsgi WSGIDaemonProcess example.com user=joe group=joe processes=2 threads=25 However, I wonder if it is really wise to run the wsgi daemon process as the same user (with its attendant privileges) which develops the code. Should I set up a service account whose only privilege is read-only access to the code in order to have better security? Or are my concerns overblown?

  • Retrieving an RSA key from a running instance of Apache?

    - by Nathan Osman
    I created an RSA keypair for an SSL certificate and stored the private key in /etc/ssl/private/server.key. Unfortunately this was the only copy of the private key that I had. Then I accidentally overwrote the file on disk (yes, I know). Apache is still running and still serving SSL requests, leading me to believe that there may be hope in recovering the private key. (Perhaps there is a symbolic link somewhere in /proc or something?) This server is running Ubuntu 12.04 LTS.

  • Fast user switching is logging users off instead of switching users

    - by Nathan Osman
    I have a netbook running Windows 8.1 Pro that will no longer allow more than one user to be logged in at the same time. The steps necessary to reproduce this are as follows: The current user presses WIN to bring up the start screen. The user clicks his name in the corner and a list of other users appears. As soon as one of the other names is clicked, the user is unceremoniously logged off without any prompts. This behavior seems to have started some time after upgrading to Windows 8.1 from Windows 8. Before that point, everything worked fine and more than one user could be logged in at the same time. I've tried searching for others experiencing similar problems but this appears to be unique. System Details: CPU: Intel Atom N455 @ 1.66 GHz RAM: 1 GB OS: Windows 8.1 Pro w/ Media Center 32-bit

  • Unable To Successfully Use Java Anywhere (Windows 7 64bit)

    - by Nathan Smith
    This is a bit of an odd issue: (This is with JRE 7u7 32bit.) New Lenovo W530 laptop, everything is shiny. I tried to use a java applet for the first time recently (in Chrome). I got the Java logo and it started spinning like it was going to load, but didn't get anywhere and the browser locked up. I tried IE. Same deal. Tried Firefox. Same deal. So, I did the usual things: Rebooted, nothing. Un-installed Java, rebooted, re-installed, nothing. Tried it installing a 64bit Java as well. Same thing. I tried JRE6. Same thing. I uninstalled and manually deleted all the registry entries I could find related to it, then re-installed. Same thing. I un-installed and used the JavaRa utility. Same exact thing. I've not been able to use web applets or desktop stuff (minecraft), until yesterday. I did a graphics driver update and I was able to play minecraft for small amounts of time. It crashed regularly and wouldn't start reliably. No change in web applets. I'm at my wits end here. I'm to the point where reformatting is my only option. If anyone has any ideas at all, that would be awesome.

  • Avast Antivirus downloading data from net even when told not to update.

    - by Nathan W
    Hi all, This is a strange problem that I have never seen before. I have two machines, both running Win 7 and running the latest version of Avast, both seem to be downloading large amounts of data. I noticed it when we were using more data for our monthly limit then normal, 2gb+ in a couple of days when really only browsing. I installed NetLimiter and let it run for couple of hours and this is the result for the avast! Service (c:\program files\alwil software\avast5\avastsvc.exe ). The other computer downloaded twice as much data in the same amount of time. Both installs of avast have their automatic updates (turned off at 4:00pm), for both program and definitions. Does anyone know what might be going on here.

  • Quick access to program shortcut

    - by Nathan DeWitt
    I need to edit a text file on my computer that requires admin access (hosts). I used to do this by hitting WIN and typing "Note". The shortcut for Notepad would show up, and I could right-click and choose Run as Administrator. How do I accomplish the same thing in Windows 8? Notepad isn't something I see pinned to my start menu, and I don't really want to clutter up my menu with something I may use infrequently. I want very quick access to my programs by typing a few letters in the name. If I use WIN-R, I have to know exactly the name of the executable. I want to just type Glob and see options for Sonic Global VPN. And I want to be able to execute that found executable as an admin if I need to. Windows Vista & Windows 7 are excellent at this. Surely this functionality has not been deprecated in Windows 8...

  • Windows 7 using exactly HALF the installed memory

    - by Nathan Ridley
    I've taken this directly from system information: Installed Physical Memory (RAM) 4.00 GB Total Physical Memory 2.00 GB Available Physical Memory 434 MB Total Virtual Memory 5.10 GB Available Virtual Memory 1.19 GB Page File Space 3.11 GB Also the BIOS reports a full 4GB available. Note the 4gb installed, yet 2gb total. I understand that on a 32 bit operating system, you'll never get the full 4gb of ram, however typically you'll get in the range of 2.5-3.2gb of ram. I have only 2gb available! My swap file goes nuts when I do anything! Note that I have dual SLI nvidia video cards, each with 512mb of on board ram, though I have the SLI feature turned off. Anybody know why Windows might claim that I have exactly 2gb of ram total? Note: previously asked on SuperUser, but closed as "belongs on superuser" before this site opened: http://serverfault.com/questions/39603/windows-7-using-exactly-half-the-installed-memory (I still need an answer!)
