  • File Upload in GWT in a Special Case

    - by Maksud
    I am doing a software for a document system. In this system when a user completes a document and want to save it, the document will be uploaded directly to server without the user action. This system uses COM/ActiveX to facilitate user using native editors. Ok, my problem is: suppose I have a file say d:/notepad.txt. Using classical method a user can browse the file and upload it. I can do that with apache commonio and GWT FormPanel and FileUpload. But if I know the filename (d:/notepad.txt), is there any way to upload the file directly to server without the user having to browse the file. I am currently doing this by the ActiveX componenet calling some HttpUpload methods with POST. But that does not maintain session. Thanks

  • Large Scale VHDL techniques

    - by oxinabox.ucc.asn.au
    I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)

  • Is it possible to modify ASP.NET to no longer require runat="server"?

    - by sean2078
    I know why runat="server" is currently required (ASP.NET why runat="server"), but the consensus is that it should not be required if you incorporate a simple default into the design (I agree of course). Would it be possible to modify, extend, decompile and recreate, intercept or otherwise change the behavior of how ASP.NET parses ASPX and ASCX files so that runat="server" would no longer be required? For instance, I assume that a version of Mono could be branched to accomplish this goal. In case specific requirements are helpful, the following highlights one design: During parsing, when configured namespace tags are encountered (such as "asp"), default the element's runat property to "server" During parsing, when configured namespace tags are encountered (such as "asp"), if the element's runat property value is available, then that value should be used in place of the default New page-level setting introduced (can be set in the page directive or web.config) that specifies the default runat value for a specific namespace tag

  • Compressing large text data before storing into db?

    - by Steel Plume
    Hello, I have application which retrieves many large log files from a system LAN. Currently I put all log files on Postgresql, the table has a column type TEXT and I don't plan any search on this text column because I use another external process which nightly retrieves all files and scans for sensitive pattern. So the column value could be also a BLOB or a CLOB, but now my question is the following, the database has already its compression system, but could I improve this compression manually like with common compressor utilities? And above all WHAT IF I manually pre-compress the large file and then I put as binary into the data table, is it unuseful as database system provides its internal compression?

  • What causes my borderless C++/CLI app to crash when overriding WndProc?

    - by Ste
    I use a form with border NONE. I need to override WndProc for resize and move form. However, using this code, my app crashes! static const int WM_NCHITTEST = 0x0084; static const int HTCLIENT = 1; static const int HTCAPTION = 2; protected: virtual void Form1::WndProc(System::Windows::Forms::Message %m) override { switch (m.Msg) { case WM_NCHITTEST: if (m.Result == IntPtr(HTCLIENT)) { m.Result = IntPtr(HTCAPTION); } break; } Form1::WndProc(m); } virtual System::Windows::Forms::CreateParams^ get() override { System::Windows::Forms::CreateParams^ cp = __super::CreateParams; cp->Style |= 0x40000; return cp; } How can I fix my code not to crash but still allow my form to be moved and resized?

  • What Are Basic Tools For A New Project?

    - by Morgan Cheng
    For a long time, I thought that to start a new project we only need 3 basic tools. 1) A Build System (e.g. Maven & CruiseControl) 2) A Version Control System (e.g. CVS & SVN & GIT) 3) A Bug Tracking System (e.g. Bugzilla) Yesterday, a senior guy told me that we need at least one thing more. That is KPI(Key Performance Index). Without KPI, it is impossible to measure whether the project is progressing well or not. KPI is kind of SOFT tool compared to Maven/SVN/Bugzilla. I believe since I missed SOFT tools, there must be some other kind of tools I missed. So, anybody get some ideas what other basic tools necessary for a new project?

  • Can a 32-bit RHEL4 userland work with a 64-bit kernel?

    - by James
    Is there a way to change an i386 RHEL4 machine to run an amd64 kernel, but ensure that it still builds software into same i386 binaries? On Debian this seems quite straightforward: just install an amd64 kernel (worst case, build one like this guy: http://www.debian-administration.org/users/jonesy/weblog/1) and prefix everything with "linux32". Then everything that considers uname -m will be unchanged, I just need to handle the few cases that consider uname -r. What is the Red Hat equivalent? Is the only way a full 64-bit installation on another disk and then chrooting back to the 32-bit system before anyone builds anything? (Even the best examples of that seem to be Debian-based.) Background: We make a large system that runs on (a variant of) i386 RHEL4. However, some of the larger RHEL build machines now have enough RAM that they might benefit from going 64-bit (for the kernel and maybe some of the bigger build steps). Our build system doesn't support cross-compilation.

  • Hang while starting several daemons

    - by Adrian Lang
    I’m running a Debian Squeeze AMD64 server. Target runlevel after boot is runlevel 2, which includes rsyslogd, cron, sshd and some other stuff, but not dovecot, postfix, apache2, etc. The system fails to reach runlevel 2 with several symptoms: The system hangs at trying to start rsyslogd Booting into runlevel 1 works, then login from the console works Starting rsyslogd from runlevel 1 via /etc/init.d/rsyslog hangs Starting runlevel 2 with rsyslogd disabled works But then, logging in via console fails: I get the motd, and then nothing Starting sshd from runlevel 1 succeeds But then, I cannot login via ssh. Sometimes password ssh login gives me the motd and then nothing, sometimes not even this. Trying to offer a public key seems to annoy the sshd enough to not talk to me any further. When rebooting from runlevel 1, the server hangs at trying to stop apache2 (which is not running, so this really should be trivial). Trying to stop apache2 when logged in in runleve 1 does hang as well. And that’s just the stuff which fails all the time. RAM has been tested, dmesg shows no problems. I have no clue. Update: (shortened) output from rsyslogd -c4 -d called in runlevel 1 rsyslogd 4.6.4 startup, compatibility mode 4, module path '' caller requested object 'net', not found (iRet -3003) Requested to load module 'lmnet' loading module '/user/lib/rsyslog/lmnet.so' module of type 2 being loaded conf.c requested ref for 'lmnet', refcount 1 rsylog runtime initialized, version 4.6.4, current users 1 syslogd.c requested ref for 'lmnet', refcount now 2 I can kill rsyslogd with Strg+C, then. /var/log shows none of the configured log files, though. Update2: Thanks to @DerfK I still have no clue, but at least I narrowed down the problem. I’m now testing with /etc/init.d/apache2 stop (without an apache2 running, of course) which hangs as well and looks like an even more obvious failure. After some testing I found out that a file with one single line: /usr/sbin/apache2ctl configtest /dev/null 2&1 hangs, while the same line executed in an interactive shell works. I was not able to further reduce this line while, i. e. every single part, the stream redirections and the commando itself is necessary to reproduce the hang. @DerfK also pointed me to strace which gave a shallow hint about what kind of hang we have here: wait4(-1for the init scripts futex(0xsomepointer, FUTEX_WAIT_PRIVATE, 2, NULL for rsyslogd / apache2 binaries called by the init scripts The system was installed as a Debian Lenny by my hoster in autumn 2011, I upgraded it to Squeeze immediately and kept it up to date with Squeeze, which then used to be testing. There were no big changes, though. I guess I never tried to reboot the system before.

  • Custom Expression in Linq-to-Sql Designer

  • How to Programmatically Identify a PI Font (a Dingbat) under OS X

    - by Glenn Howes
    There is a class of fonts called Pi fonts whose glyphs, under OS X, get mapped to the private Unicode space 0xF021-0xF0FF such that if you subtract 0xF000 from each unicode character to retrieve the 8-bit version of the character and be able to draw that character as if it were a standard Roman character. My question is how do I recognize these fonts? It's obvious the system can do so because there is a category on the Special Characters palette called "Pi Fonts" which apparently has the various such fonts installed on my system. In my case they are BookshelSymbolSeven, MSReferenceSpeciality, MT-Extras, Marlett, MonotypeSorts, Webdings, and various Wingdings. If I use the old fashioned QuickDraw routines to ask for the TextEncoding of these fonts, I get a value of 0x20000 which I do not see in the system header file TextCommon.h. Am I supposed to treat any font with a TextEncoding of 0x20000 as a Pi Font? And I'd rather not use any QuickDraw font handling routines for obvious reasons.

  • SecurityException from Activator.CreateInstance(), How to grant permissons to Assembly?

    - by user365164
    I have been loading an assembly via Assembly.LoadFrom(@"path"); and then doing Type t = asm.GetType("Test.Test"); test = Activator.CreateInstance(t, new Object[] { ... }); and it was working fine, but now I moved the dll I am getting the following System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.Security.SecurityException: Request for the permission of type 'System.Security.Permissons.SecurityPermission, etc .. For the sake of brevity it seems the demand was for an PermissionSet that allowed ControlAppDomain and it's not getting it. My question is how can I create this permissionset and pass it to the instance or assembly? I've been googling for hours to no avail.

  • Partition adjustment on live server

    - by keithwarren7
    Windows Server 2008 SP2 I have a server currently running several sites in production. It is partitioned in such a way that the System partition is small with just windows and the necessary program files and all the data is on another partition (the way my hosting company set it up) Is there a program I can use/purchase that will allow me to resize the system partition to something larger without needing physical access to the machine (ie over RDP)

  • I have two 'WsusContent' folders. One has about 55gb of files in it. How do I clear it out?

    - by MrVimes
    I ran the WSUS cleanup wizard in the WSUS MMC snap-in but this made no difference. I think the files are associated with System Center Essentials because they are in a folder called "data\SCE2007\WsusContent" I've looked for a similar cleanup wizard in System Center Essentials but can't find one. Is there a way to clear these files out that doesn't cause issues for SCE or anything else? FYI I've got both SCE and standalone WSUS settings already set to minimize the amount of updates downloaded from Microsoft to only those that are needed.

  • Possible to mount an ext4 partition image via FUSE?

    - by Catskul
    I'm attempting to mount an ext4 partition image in userspace. (no sudo, no special config/permissions modification to /dev/loop0 or /etc/fstab etc). So I'm hoping FUSE will come to the rescue. However it seems that each file system mounted through the FUSE system needs to have a special FUSE driver, and I've not been able to find a linux read-write ext4 FUSE driver for linux. Is there a way to mount ext4 images via FUSE (with write permission)?

    Hi I have a traditional telephony system at home. I also got an voip ATA device connected to the telephone socket. On a normal phone you can just plug it into the wall socket then multiple people on different phones can speak a the same time. Currently for me to take this call whoever answered the call will forward it onto my internal number. Is there not a way I can make it work like the analogue system so I can just pick up the phone?

  • SQL Server 2008 - Error starting service - model.mdf not found?!

    - by alex
    my SQL server 2008 was running fine. About an hour ago, it suddenly stopped - the MSSQLSERVER service had stopped I right clicked, clicked start, and it said the service had started, and stopped I looked in the event log and saw these two errors: 17207 : udopen: Operating system error 3(error not found) during the creation/opening of physical device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf. 17204 : FCB::Open failed: Could not open device C:\Program Files\Microsoft SQL Server\MSSQL\data\model.mdf for virtual device number (VDN) 1. The model.mdf db has NEVER been in that location - i specified drive F: to use for data / log during install. I checked the SQL Configuration Manager, to try and set startup params, but SQL Server is not listed as one of the services..... EDIT: I've now moved the db to where it was looking for: C:\Program Files\Microsoft SQL Server\MSSQL\data\ directory. Now if I start the service, it still does not work - i get this error message in the log: Could not find row in sysindexes for database ID 3, object ID 1, index ID 1. Run DBCC CHECKTABLE on sysindexes. Interestingly, i checked the error log - around the time users reported problems, there is this: 2010-01-08 17:11:26.44 spid51 Configuration option 'show advanced options' changed from 0 to 1.

  • EBS with RAID0 (striping) and restoring snapshots

    - by grourk
    We have a MySQL database on EC2 and are looking at the disk IO performance there. Currently we have a single EBS volume with XFS and take snapshots for backup. It seems that a lot of people have seen significant performance gains by striping across multiple EBS volumes with software RAID. If this is done, how does one take snapshots and ensure the consistency of the file system? It seems to me that restoring the file system from multiple snapshots could be tricky.

If so, how? EDIT #1: I added the following: Console.WriteLine( "user: " + user ); Below this line: UserPrincipal user = UserPrincipal.FindByIdentity(context, "someLimitedAccount"); And I get this: user: It doesn't look like user is null when I print it, but then again I'm not really a .Net guy - I seem to remember this being expected behavior.
