  • Adding new records in Access without wrecking the form

    - by Matt Parker
    I'm working on a simple Access 2003 application to keep track of things that need to be done for clients for some colleagues. Each colleague has a set of clients, and each client has a set of actions that need to be taken by a certain date. I've set up a form that consists of a combobox for client ID (indexed), a drop-down for the person who is handling that client's case, and a button for adding new clients (a standard Access-created Add Record button). The actions are listed in a subform below these three elements. The problem I've run into is that the first person I tested this on clicked the button to add a new record, then didn't fill it out and tried to select another client from the drop-down list. Access interprets this as an attempt to set the selected Client ID as the ID for the new record and rightfully throws an error for duplicate primary keys. I can think of a couple of ways around this problem, but I'd much rather hear your elegant solutions than kludge together some junk in a language I don't know. Let me know if you have any questions. Thank you.

  • jCarousel jQuery ajax loading 1000 records

    - by user1714862
    I'm using jCarousel to present a vertical scolling list of +-1000 names. I am using ajax to load the data 100 records at a time then when all the data has loaded I just let the jCarousel loop in the DOM. I have the ajax and loop all working but would like to make the code work no matter how large the total record count becomes. 1) I'd like to eliminate the 1201 fixed number and use a variable. 2) I currently loop on every record I see (carousel.first) to see if it matches my reload position(s) (albeit the loop is ony 12x it still seems a little "loopy") Any suggestions on improving this? function mycarousel_itemLoadCallback(carousel, state) { //if (carousel.has(carousel.first, carousel.last)) { //return; //} var getCount = 100; // Number of records to grab at a time var maxCount = 1201; // total possible number of records var visible = 9; // the number of records you can see in the window so this creates a pre-load by this number of records for (var i = 1; i < maxCount; i+=getCount ) { if (carousel.first === 1 || carousel.first === (i-visible)){ var getFrom = i; var getTo = getFrom+(getCount-1); //alert('TOP Record ='+carousel.first+'\n Now GET '+getFrom+'-'+getTo); jQuery.get('#ajaxscript#', { first: getFrom, last: getTo }, function(xml) { mycarousel_itemAddCallback(carousel, getFrom, getTo, xml); }, 'xml' ); break; } } };

  • Tracking down origin of I/O in multi-process server

    - by Craig Ringer
    I'm currently trying to track down some phantom I/O in a PostgreSQL build I'm testing. It's a multi-process server and it isn't simple to associate disk I/O back to a particular back-end and query. I thought Linux's perf tool would be ideal for this, but I'm struggling to capture block I/O performance counter metrics and associate them with user-space activity. It's easy to record block I/O requests and completions with, eg: sudo perf record -g -T -u postgres -e 'block:block_rq_*' and the user-space pid is recorded, but there's no kernel or user-space stack captured, or ability to snapshot bits of the user-space process's heap (say, query text) etc. So while you have the pid, you don't know what the process was doing at that point. Just perf script output like: postgres 7462 [002] 301125.113632: block:block_rq_issue: 8,0 W 0 () 208078848 + 1024 [postgres] If I add the -g flag to perf record it'll take snapshots of the kernel stack, but doesn't capture user-space state for perf events captured in the kernel. The user-space stack only goes up to the entry-point from userspace, like LWLockRelease, LWLockAcquire, memcpy (mmap'd IO), __GI___libc_write, etc. So. Any tips? Being able to capture a snapshot of the user-space stack in response to kernel events would be ideal.

  • Allowing Xform controls for optional XML elements

    - by Cam
    Hi, In designing an XForm interface to an XML database (using eXist and XSLTForms), I'd like to include an input control for an optional element. The XML data records already exist and while some contain the optional element, others don't. To update a record, I'm using the existing XML record as the model instance. The problem is that the form control is not displayed when the optional element is not present, which is logical, but presents a problem when a user wants to add data to the optional element. To be more explicit, here's an example data record, data.xml: <a> <b>content</b> </a> with RNC schema: start = element a { element b { text }, element notes { text }? } XForms model: <xf:model> <xf:instance xmlns="" src="data.xml"/> <xf:submission id="save" method="post" action="update.xq" /> </xf:model> And control: <xf:input ref="/a/notes"> <xf:label>Notes (optional): </xf:label> </xf:input> The problem is that the 'Notes' input control is simply not displayed. An obvious solution is to add a trigger button to allow the user to insert the element if needed, but it is preferable to just have the input control appear, and be empty. My question is: is there some subtle combination of lesser-know attributes/binds/multiple instances/xpath expressions that will cause the control to always be displayed? Thanks

  • Hibernate saveOrUpdate fails when I execute it on empty table.

    - by Vladimir
    I'm try to insert or update db record with following code: Category category = new Category(); category.setName('catName'); category.setId(1L); categoryDao.saveOrUpdate(category); When there is a category with id=1 already in database everything works. But if there is no record with id=1 I got following exception: org.hibernate.StaleStateException: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1: Here is my Category class setters, getters and constructors ommited for clarity: @Entity public class Category { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; @ManyToOne private Category parent; @OneToMany(fetch = FetchType.LAZY, mappedBy = "parent") private List<Category> categories = new ArrayList<Category>(); } In the console I see this hibernate query: update Category set name=?, parent_id=? where id=? So looks like hibernates tryis to update record instead of inserting new. What am I doing wrong here?

  • Creating nested fields for column on assignment table?

    - by H O
    I have three models, that represent a many to many relationship - Product, Sale and Product_sale. I have a nested form that allows me to create new products from the sale form - so far, so good. I have, however, added some additional fields to the assignment table - price, for example. How can I set the price on the assignment table from the product form, when it is nested in the sale form? I currently have the code below: <%= sale.fields_for :products do |products_builder| %> <%= render :partial => "products/form", :locals => {:f => products_builder, :form_actions_visible => false} %> <% end -%> I could nest a Product_sale form within the product form, but this would create a new product_sale, which is not what I am looking for. I will most likely need to nest the price field within the product form, to ensure that it updates the correct assignment record (since there could be multiple products on one sale form). How can I use a fields_for loop on the product form to update the existing assignment record that is built when I do @sale.products.build? The assignment record will not yet be saved, so I can not access it using a where clause and edit it that way. Thanks!

  • fluent nhibernate - storing and retrieving three classes in/from one table

    - by Will I Am
    Noob question. I have this situation where I have these objects: class Address { string Street; string City; ... } class User { string UserID; Address BillingAddress; Address MailingAddress; ... } What is the proper way of storing this data using (fluent) nHibernate? I could use a separate Address table and create a reference, but they are 1:1 relationships so I don't really want to incur the overhead of a join. Ideally I would store this as a single flat record. So, my question is, what is the proper way of storing an instance of class 'User' in such a way that it stores its contents and also the two addresses as a single record? My knowledge is failing me on how I can store this information in such a way that the two Address records get different column names (e.g. BillingAddress_Street and MailingAddress_Street, for example), and also how to read a record back into a User instance.

  • guarantee child records either in one table or another, but not both?

    - by user151841
    I have a table with two child tables. For each record in the parent table, I want one and only one record in one of the child tables -- not one in each, not none. How to I define that? Here's the backstory. Feel free to criticize this implementation, but please answer the question above, because this isn't the only time I've encountered it: I have a database that holds data pertaining to user surveys. It was originally designed with one authentication method for starting a survey. Since then, requirements have changed, and now there are two different ways someone could sign on to start a survey. Originally I captured the authentication token in a column in the survey table. Since requirements changed, there are three other bits of data that I want to capture in authentication. So for each record in the survey table, I'm either going to have one token, or a set of three. All four of these are of different types, so my thought was, instead of having four columns where either one is going to be null, or three are going to be null ( or even worse, a bad mashup of either of those scenarios ), I would have two child tables, one for holding the single authentication token, the other for holding the three. Problem is, I don't know offhand how to define that in DDL. I'm using MySQL, so maybe there's a feature that MySQL doesn't implement that lets me do this.

  • Drupal 7 - I can't pass post data in module function

I can browse to http://mysite.com/getstates ok but when I call this function using ajax it is not passing the value of "test" which is "1" to $_POST["test"]. I am new to Drupal so I am positive that I miss something here. I thought I need a new set of eyes.

  • What is the most challenging part of a project like MyLifeBits

    - by kennyzx
    I have made a small utility to keep track of my daily expenses, and my coffee consumption (I always want to quit coffee but never succeed), and of course, this kind of utility is quite simple, just involving an xml file and a few hundred lines of code to manipulate the file. Then I find this project MyLifeBits, it is very intesting, but I think it should require a lot of effort to achieve its goal- that is, to record everything about a person that can be digitally record. So I wonder, it is possible to write an advanced version of my own utility - but a tiny version of MyLifeBits, that can capture: Every webpage I've read, no matter what browser I am using, just download its contents for offline reading, Auto archive emails/documents/notes that I edited, Auto archive Codes that I run/written. Well, these are basically what I do on my PC. And the captured records can be searched easily. My question is, What do you think is the most challenging part? Interoperating with Visual Studio/Office/Lotes Notes/Web browsers is one thing, Database is another thing given that "everything" is record, Advanced programming patterns since it is not a "toy project"? And others that I have overlooked but can be very difficult to handle?

  • Windows file locks allowing multiple users to write to open file over network

    - by JPbuntu
    I have 6 windows computers (xp,vista,7) that need to access a samba share (Ubuntu 12.04). I am trying to make it so only one client can open a file at a given time. I thought this was pretty standard behavior of file locks, but I can't get it to work. The way it is right now a file can be open by two users, and changed and saved by either one of them. The last file saved overwrites what ever changes the other user made. At first I thought this was a Samba configuration problem, but I get this behavior even between two windows machines. So far I have only tested: Windows Xp Windows Vista Windows XP Samba << Windows Vista and both give the same behavior. When I tested the Samba configuration, I had set strict locking = yes and get errors logged like this: close_remove_share_mode: Could not get share mode lock for file _prod/part_number_list_COPY.xlsx Eventually all of the files are going to be moved onto the Samba share, so that is the configuration I am most concerned about fixing. Any ideas? Thanks in advance. EDIT: I tested an excel file again, and it is now working properly in both above mentioned cases, I am also no longer getting the above mentioned error. I don't know what happened, perhaps a restart fixed it? (also works with strict locking = no) Although I still need to find a solution for the CAD/CAM files we use, the software is Vector and it does not seem to be using file locks. Is there any software that I can use to manage these files, so two people can't open/edit them at a time? Maybe a windows application that forces file locks? Or a dirt simple version control system? (the only ones I have seen at are too complicated for our needs).

  • Networking Problem MrxSmb event 50 "Delayed Write Failed" errors occurring all of the sudden

    - by Johnny Musso
    JUST THIS MONTH, we have started getting reports from a number of very stable clients that MrxSmb event id 50 errors keep appearing in their system event logs. Otherwise, they do not appear to have any networking problems except that there is a critical legacy application which seems to either be generating the MrxSmb errors or having errors occur because of them. The legacy application is comprised of 16 bit and 32 bit code and has not been changed or recompiled in many years. It has always been stable on Windows XP systems. The customers that have the problem usually have a small (5 clients or less) peer to peer network with all Windows XP systems. All service packs are loaded on the XP machines. Note: The only thing that seems to correct the problem is disabling opportunistic locking. I don't like this solution because it seems to slow down the network and sometimes causes record locking issues between users (on some networks). Also, this seems to have just started happening - as if a Windows update for XP has caused it? However, I have removed recent updates and it did not correct the issue. Thanks in advance for any help you can provide.

  • How to prevent samba from holding a file lock after a client disconnects?

    - by Jean-Francois Chevrette
    Here I have a Samba server (Debian 5.0) thats is configured to host Windows XP profiles. Clients connects to this server and work on their profiles directly on the samba share (the profile is not copied locally). Every now and then, a client may not shutdown properly and thus Windows does not free the file locks. When looking at the samba locking table, we can see that many files are still locked even though the client is not connected anymore. In our case, this seems to occur with lockfiles created by Mozilla Thunderbird and Firefox. Here's an example of the samba locking table: # smbstatus -L | grep DENY_ALL | head -n5 Pid Uid DenyMode Access R/W Oplock SharePath Name Time -------------------------------------------------------------------------------------------------- 15494 10345 DENY_ALL 0x3019f RDWR EXCLUSIVE+BATCH /home/CORP/user1 app.profile/user1.thunderbird/parent.lock Mon Nov 22 07:12:45 2010 18040 10454 DENY_ALL 0x3019f RDWR EXCLUSIVE+BATCH /home/CORP/user2 app.profile/user2.thunderbird/parent.lock Mon Nov 22 11:20:45 2010 26466 10056 DENY_ALL 0x3019f RDWR EXCLUSIVE+BATCH /home/CORP/user3 app.profile/user3.firefox/parent.lock Mon Nov 22 08:48:23 2010 We can see that the files were opened by Windows and imposed a DENY_ALL lock. Now when a client reconnects to this share and tries to open those files, samba says that they are locked and denies access. Is there any way to work around this situation or am I missing something? Edit: We would like to avoid disabling file locks on the samba server because there are good reasons to have those enabled.

  • OS X: Storing MySQL data securely, on an encrypted FileVault image using a soft link

    - by GJ
    I am trying to get a macports-installed MySQL to use a data directory stored inside my FileVault-protected home dir. I used sudo cp -a /opt/local/var/db/mysql5 ~/db/ (the -a to ensure file permissions remain intact) and then replaced the original mysql5 directory with a soft link: sudo ln -s ~/db/mysql5 /opt/local/var/db/mysql5 However, when I now try to start MySQL it fails. It follows the soft link at least to the extent that it modifies some files in the ~/db/mysql5 dir, notably the error log which gets appended to it this: 110108 15:33:08 mysqld_safe Starting mysqld daemon with databases from /opt/local/var/db/mysql5 110108 15:33:08 [Warning] '--skip-locking' is deprecated and will be removed in a future release.

    I wanted to ask a multi-part question. Does Comcast Cable Internet services record MAC Addresses of the Router behind the cable modem. I know they record it for the modem itself. But is there a way for the Modem/Comcast to relay and keep logs of the MAC ID of the Router itself? Then does a windows operating system Log the MAC ID of the Router when its connected to it? If so where do I locate and purge this? Please let me know all areas where it is Logged within the operating system. Thank you!

  • Cisco ASA Hairpinning with Dynamic IP

    - by Joseph Sturtevant
    I currently have my Cisco ASA 5505 firewall configured to forward port 80 from the outside interface to a host on my dmz interface. I also need to allow clients on my inside interface to access the host in the dmz by entering the public ip / dns record in their browsers. I was able to do that by following the instructions here, resulting in the following configuration: static (dmz,outside) tcp interface www 192.168.1.5 www netmask 255.255.255.255 static (dmz,inside) tcp 74.125.45.100 www 192.168.1.5 www netmask 255.255.255.255 (Where 74.125.45.100 is my public IP and 192.168.1.5 is the IP of the dmz host) This works great except for the fact that my network has a dynamic public IP and this configuration will therefore break as soon as my public IP changes. Is there a way to do what I want with a dynamic ip? Note: Adding an internal DNS record won't solve my problem since I have multiple dmz hosts mapped to different ports on the public IP.

  • Got black screen when recording screen from xvfb by ffmpeg x11grab device

    - by shawnzhu
    I'm trying to record video from a firefox run by xvfb-run but it always output nothing in the video file except black screen. Here's what I did: start a firefox, open google.com: $ xvfb-run firefox https://google.com Then it will use the default display server number 99. I can see the display information by command xdpyinfo -display :99. A screenshot works very well by command: $ xwd -root -silent -display :99.0 | xwdtopnm |pnmtojpeg > screen.jpg Start using ffmpeg to record a video: $ ffmpeg -f x11grab -i :99.0 out.mpg When I play the video file out.mpg, there's black screen all the time. Is there any parameter I missed? Updates I made progress that the video works instead of black screen only by this command: $ ffmpeg -y -r 30 -g 300 -f x11grab -s 1024x768 -i :99 -vcodec qtrle out.mov Notice it requires the screen resolution matches by specify more options to xvfb-run: $ xvfb-run -s "-screen 0 1224x768x16" -a firefox http://google.com But I still want to get more feedbacks and answers here.

  • james - mail server DNS configuration

    - by Chaitanya
    hi, I am setting up james mail server. I installed James and added in the config.xml added the servername as mydomain.com. In the DNS for mydomain.com, I have created a A-record, say mx.mydomain.com, which corresponds to the ipaddress of the above mail server machine. Then added mx.mydomain.com as MX record for mydomain.com. In James, I have created a new user test. From the user I have sent a mail to my gmail account. I see that the mail is accepted and the mail is in outgoing folder of James. But it's not relay to the gmail server. In the config.xml of James, I have added 8.8.8.8 and 8.8.4.4 as the dns server addresses, which are public DNS servers hosted by Google. IPTables on the machine is stopped. Thanks for your help!

  • Encode real-time dvb-s stream using mencoder

    - by karatchov
    My satellite receiver can stream the mpeg-2 video/audio output through lan. Using mencoder, I'm trying to build a script to encode and save the stream in real time with my Core2Duo 1.8 Ghz. Right now, I'm using a single pass, it produces good quality for a video rate of 800Kb/s, but takes more then 95% of CPU power, thus making a lot of frameskips is the computer is used while encoding. mencoder -o -vf lavcdeint -oac mp3lame -lameopts abr:q=2:aq=2 -ovc x264 -ffourcc avc1 -x264encopts crf=25:me=hex:subq=9:frameref=2:nocabac:threads=auto -mc 3 So, I'm considering using a 2-pass encoding to alleviate the processor and record 100% of the stream. But I have no idea how to start. For the info: Standard Stream: mpeg-2 720*576 25fps HD Stream: 1920*1080 50fps (this is not my goal to record it, but it will be super cool if I could)

There is "MX" record for domain3 and no "A" records for domain3, only one for "www.domain3" Update" all domains are public and have fully-qualified names, all dns's are accessible." Update2: domain1 has only "A" record, but not the MX one. Can it be a problem?

  • DNS - Redirect from old server to new.

    - by jyoseph
    I have a server, (Server A) Windows Server 2003 that I was hosting some sites on. Now they are hosted on a different server (Server B). I recently switched the DNS at godaddy to point to the new nameservers. Is there something I can do on Server A to point all requests to Server A to Server B (basically a redirect from Server A to B)? What type of record would that be? This is while I'm waiting for the DNS changes I made to fully resolve. edit To further clarify. test.com may still be resolving to Server A, I'd like a DNS record on Server A that tells it to go to the new server. Is that possible?
