  • mscomctl.ocx on my dev machine gives me problems since security patch of MS

    - by Bronzato
    I am busy on this problem since 2 days ago and hope someone can get me out of it. I have Excel 2010 (full install 944Mb) on my Windows 8 computer. It works well. But when I modify my workbook (containing a ListView version 6.0) I am not able to run it on my client's computer. I get the error: Could Not Load An Object. Not Available on This Machine. Even it works well on my dev machine. The reason is: Microsoft applied a Security Patch (near august 2012 I think) on mscomctl.ocx and my Excel 2010 installation files (downloaded not long ago) contains the new version of mscomctl.ocx. The clients using my Excel file don't apply the security patch at this moment. Se everytime I publish my Excel file to client's computers (from my dev environment), I reference the new mscomctl.ocx. That's the problem. I already try to get the old mscomctl.ocx from client's computer and copy & register it on my dev machine but then I got errors (Class not registered, ...) when I create a userform and drag a listview on it. So: mscomctl.ocx on client's machine is version 6.1.98.13 from 2008. mscomctl.ocx on my dev machine is version 6.1.98.34 from 2012. My question: Does someone have an idea how to proceed to have a usable version of mscomctl.ocx on my dev machine? Thank you very much.

  • JQuery not copying state dropdown list 1 to DDL2 on checkbox change

    - by user1001411
    I've looked at similar posts on the subject but none of the recommended solutions have worked for me so I'm not sure where I'm going wrong. I have a billing and shipping address form with a dropdown list for the state. Upon checking/unchecking the "billing address same as shipping" everything copies over except the state dropdown list. The state dropdown list is populated from a SQLDataSource state table. Here's my code: <script type="text/javascript" language="javascript" src="../Scripts/jquery-1.4.1.min.js"></script> <script type="text/javascript"> $(document).ready(function () { $('input:checkbox[id*=chkCopy]').change(function () { if ($(this).is(':checked')) { $('input:text[id*=TextBox5]').val($('input:text[id*=TextBox1]').val()); $('input:text[id*=TextBox7]').val($('input:text[id*=TextBox2]').val()); $('input:text[id*=TextBox9]').val($('input:text[id*=TextBox3]').val()); $('input:text[id*=TextBox12]').val($('input:text[id*=TextBox4]').val()); $('select#DropDownList6').val($("select#DropDownList1").val()); $('input:text[id*=TextBox14]').val($('input:text[id*=TextBox6]').val()); } else { $('input:text[id*=TextBox5]').val(''); $('input:text[id*=TextBox7]').val(''); $('input:text[id*=TextBox9]').val(''); $('input:text[id*=TextBox12]').val(''); $('select#DropDownList6').val(''); $('input:text[id*=TextBox14]').val(''); } }); }); and here is my SQL for the DDL: <asp:DropDownList ID="DropDownList1" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource1" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource> the other one: <asp:DropDownList ID="DropDownList6" runat="server" DataTextField="Descr" DataValueField="ID" DataSourceID="SqlDataSource5" Width="254"> </asp:DropDownList> <asp:SqlDataSource ID="SqlDataSource5" runat="server" ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString1 %>" SelectCommand="SELECT * FROM [xrefState]"> </asp:SqlDataSource>

  • Maintain state of an ASP.NET page

    - by user279521
    Hi, what is your preferred method to maintain state of an asp.net page, if it is a public website (involving shopping cart, wish-list etc). I am in the process of designing a website that will need to ensure that the user is not able to tamper with the state (such as delete cookies etc).

  • Remember JVM state before executing a specific instruction.

    - by user559064
    I am working on a testing project using mutating technique. My project requires to manipulate a Java classfile and re-execute the classfile multiple times for testing. My implementation need to re-execute the whole system again after one manipulation, and that is not efficient. I am wondering whether I can save the JVM state right before executing a desired instruction in the classfile, so that I can start from that state after each manipulation. Thank you.

  • Filesystems for webserver with SATA and Solid State disk,

    - by Jorisslob
    We have just ordered a new webserver with 120 Gb solid state disk and a SATA disk. I am trying to plan ahead what sort of filesystem to use. This system will be running Linux, Apache/Tomcat to host java services. The main service is a system where people can upload reasonably large files (in the order of 100 Mb, images, image stacks and video), which people will be able to annotate and which will be sent to a database server when annotation is complete. Thus far, I plan to put most of the utility programs of the operating system om the SSD and put the large media files there. The SATA disks will hold the less volitile data like apache, tomcat and the servlets. For filesystems I have considered going for the stable EXT3 because I hear that it is best supported. The downside seems to be that it not the ideal choice for large files. That is why I am leaning towards using XFS for the SSD and EXT3 for the SATA. My questions are: 1) Does this sound like a reasonable setup? 2) What filesystems would you recommend for the SSD and for the SATA? Thanks

  • Computer loses all installed programs and appears to return OS-only state

    - by Jake
    This is a story regarding 3 laptops of different brand and models. On separate occassions, I configured each of these Windows 7 / Vista computers with the necessary configuration and applications (which are supposedly the same actually), e.g. join office domain, same windows updates, microft office etc. These machinese were configure in our office in Singapore, and then they were taken to India for use. Someday in India, when booting up the laptop, all went fine except when it reach the log in screen, it was no longer possible to login with domain credentials. Logging into the laptop local admin account will lead to discover that the machine has returned to "OS-only state". All the configurations and applications were gone. The actual user profiles are still in the C: drive so files can still be retrieved, but under Control Panel Uninstall Programs it is evident that at least the registry is corrupted. The above scenario happen to the first 2 laptops. For the third, the system reports "Operating System Not Found" on boot up. I cannot think of any reason except to suspect a power fluctuation issue. Question is, will a power issue create this behaviour? What else can cause this issue?

  • Mysql queries stuck in "sending data" state

    - by MarkPW
    I'm running a Litespeed web server and a database server (2 x Clovertown 5335) with MySQL 5.1.52-log (running on Cent OS 4.5 and 4.6 32bit respectively). Last week, I upgraded from 5.0.51a-community-log and since then I've been having a problem whereby my database server's load starts increasing for no apparent reason. Running SHOW PROCESSLIST; I see all of my SQL_CACHE queries that use a wildcard in WHERE, backing up and getting stuck in "sending data" state. However, other queries that use SQL_CACHE but no wildcard do not get caught up in this. To get things going again, the first time it happens (after about 24 hours), I have to restart mysql. 4/5 times it will re-occur after about 20 minutes or so and this time and for subsequent occurrences it is not necessary to restart mysql. Simply stopping the web server for a few minutes will suffice while I allow the stuck queries to clear themselves up. I had no such problem with the the previous mysql install. What could be causing the issue and how do I resolve it? Thanks

  • How to uninstall files and software from a Solid State Drive (SSD)

    - by jasondavis
    I am using a SSD drive just as a main Operation system and software drive. I have a regular spinning disk for data files. I have read that files are not REALLY deleted from a SSD drive when you "delete" them. So here is my situation and hopefully I can get some good advice. Let's say I have Windows 7 Pro x64bit installed on my 80gb Intel SSD. I then have Adobe Photoshop CS4 installed along with 50 other programs installed onto this SSD. I then decide I am done with Adobe Phjotoshop CS4 and want to remove it. I then decide I want to install another version of Adobe Photoshop and a few other software titles. Would I just do the usual, add/remove software from the windows control panel. Or if the software being removed has an "Uninstall" program to run, then run it and uninstall the software? I realize that all this WILL remove the software from Windows 7 but I am wanting to know if there is additional steps that should be taken since it is a solid state drive (SSD)?

  • Cluster Core Resource state of Exchange 2010 DAG

    - by Christoph
    I have two Exchange 2010 servers in a DAG and a witness server to implement mailbox resiliency. The two Exchange servers are in two subnets and the Windows failover cluster therefore has two IP address resources. I now that Exchange uses "core functionality" of Windows Server failover clustering, but it does not use all features. My setup also seems to work, but if I run the validation in the Windows Failover Cluster Manager, it complains about one of the IP address resources being offline. However, I cannot bring this resource online, because the server complains that "the specified cluster node is not the owner of the resource, or the node is not a possible owner of the resource". If I "Simulate failure of this resource", it becomes offline and the other IP becomes online. I have the vague idea that Exchange might use the state of the IP resource to identify the Primary Active Manager, but I am not sure. As it is obviously important that failover really works, I would like to be sure. Therefore, my question is: Is it normal that only one IP address resource in a Exchange 2010 DAG failover cluster is active at a time? If not, how do I bring both resources online at the same time given the error described above?

  • Solid State Drive Occasionally Freezes For A Minute While OS Is "Beach Balling"

    - by Boris_yo
    Almost a month ago I bought Intel 330 128GB solid state drive, migrated my data with Intel branded limited-feature Acronis from old HDD to new SSD, optimized with Intel Toolbox and started using it. Occassionally I get close to 1 minute freezes while seeing operating system "beach balls" and animations still work, I can interact and click on something but nothing responds, nothing loads. Recently a couple of such freezes occurred in shorter amount of time in a row. I have noticed that if I stop interacting with laptop, the freeze lasts less time than if I was interacting with laptop. But the bigger problem is when freeze just does not end and computer keeps being stuck unlil it is more than half hour and I run out of patience to keep waiting and feeling I need to restart the system because I am not getting anywhere. Such freeze happened while laptop was cold booting into Windows 7. This is when freeze hang occurred and I had to restart, only later to be greeted with Windows recovery screen stating something about faiure of boot sector and asking to insert Windows repair CD. But after I restarted, Windows booted successfully and all was well. I have filmed video of freeze hang occurring in cold boot which you can see here (on video page look below for description): http://www.youtube.com/watch?v=8b7MQlcDTUs As I have mentioned in the beginning, the SSD is less than a month old but here is S.M.A.R.T statistics just in case (TRIM is enabled btw according to CrystalDiskInfo): I want to emphasize that this SSD is the only drive I have, yet it is working in RAID mode (it was enabled initially in BIOS by previous laptop's owner) on Intel Rapid Storage drivers. I am contemplating about switching to AHCI mode but want to be sure this won't cause data loss. Additionally, the stock firmware is the only firmware available currently, yet Intel does not respond to my posts in their community board. If anyone here has this SSD model or generally has experience with SSD drives, I would love to know your thoughts.

  • Hadoop streaming job on EC2 stays in "pending" state

    - by liamf
    Trying to experiment with Hadoop and Streaming using cloudera distribution CDH3 on Ubuntu. Have valid data in hdfs:// ready for processing. Wrote little streaming mapper in python. When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

  • Mysql connections hanging in login state

    - by Mark Rose
    Suddenly today, I had an issue with connections to mysql hanging when connecting by IP address (e.g. mysql -h 10.1.248.20), but I could still connection using localhost fine, regardless the user. mysql> show processlist; +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ | Id | User | Host | db | Command | Time | State | Info | +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ | 1 | system user | | NULL | Connect | 10 | Connecting to master | NULL | | 2 | system user | | NULL | Connect | 10 | Has read all relay log; waiting for the slave I/O thread to update it | NULL | | 37 | unauthenticated user | 10.1.248.3:36694 | NULL | Connect | NULL | login | NULL | | 38 | unauthenticated user | 10.1.248.3:36695 | NULL | Connect | NULL | login | NULL | | 39 | unauthenticated user | 10.1.248.3:36696 | NULL | Connect | NULL | login | NULL | | 40 | root | localhost | NULL | Query | 0 | NULL | show processlist | +----+----------------------+------------------+------+---------+------+-----------------------------------------------------------------------+------------------+ 6 rows in set (0.00 sec) Yes, I realize replication was broken in that output above; that was after I tried restart MySQL (it was an emergency). And as suddenly as things stopped working, they started working again. DNS was working fine at the time. Replication was still working. MySQL was responsive. Does anyone have any idea what would cause MySQL logins from remote IPs to hang suddenly?

  • Recommended textbook for machine-level programming?

    - by Norman Ramsey
    I'm looking at textbooks for an undergraduate course in machine-level programming. If the perfect book existed, this is what it would look like: Uses examples written in C or assembly language, or both. Covers machine-level operations such as two's-complement integer arithmetic, bitwise operations, and floating-point arithmetic. Explains how caches work and how they affect performance. Explains machine instructions or assembly instructions. Bonus if the example assembly language includes x86; triple bonus if it includes x86-64 (aka AMD64). Explains how C values and data structures are represented using hardware registers and memory. Explains how C control structures are translated into assembly language using conditional and unconditional branch instructions. Explains something about procedure calling conventions and how procedure calls are implemented at the machine level. Books I might be interested in would probably have the words "machine organization" or "computer architecture" in the title. Here are some books I'm considering but am not quite happy with: Computer Systems: A Programmer's Perspective by Randy Bryant and Dave O'Hallaron. This is quite a nice book, but it's a book for a broad, shallow course in systems programming, and it contains a great deal of material my students don't need. Also, it is just out in a second edition, which will make it expensive. Computer Organization and Design: The Hardware/Software Interface by Dave Patterson and John Hennessy. This is also a very nice book, but it contains way more information about how the hardware works than my students need. Also, the exercises look boring. Finally, it has a show-stopping bug: it is based very heavily on MIPS hardware and the use of a MIPS simulator. My students need to learn how to use DDD, and I can't see getting this to work on a simulator. Not to mention that I can't see them cross-compiling their code for the simulator, and so on and so forth. Another flaw is that the book mentions the x86 architecture only to sneer at it. I am entirely sympathetic to this point of view, but news flash! You guys lost! Write Great Code Vol I: Understanding the Machine by Randall Hyde. I haven't evaluated this book as thoroughly as the other two. It has a lot of what I need, but the translation from high-level language to assembler is deferred to Volume Two, which has mixed reviews. My students will be annoyed if I make them buy a two-volume series, even if the price of those two volumes is smaller than the price of other books. I would really welcome other suggestions of books that would help students in a class where they are to learn how C-language data structures and code are translated to machine-level data structures and code and where they learn how to think about performance, with an emphasis on the cache.

  • Connectivity with SQL Server Express 2008 r2 and SQL Server 2000 on same machine

    - by Jim R
    At first glance this may same a duplicate of Installing both SQL Server 2000 and SQL Server 2008 on the same machine, but it is not. I have SQL Server 2000 and SQL Server 2008 R2 installed on the same machine and working fine. My problem lies with connecting to the 2008 R2 server from a remote machine. My connectivity needs to be TCP. The legacy installation or SQL 2000 uses the default port of 1433. The named instance is by default configured to use 'Shared Memory' and is working fine. When I configured the 2008 R2 server to use 1433 (I did not think that thru) the service refused to start becasue 1433 was already in use by the legacy SQL 2000 default instance. Doh! What I want to do is have both servers available simultaneously via TCP. both servers need not be on the same port, put if I cannot run them on the same port, then how do I configure the clients? Is there not some kind of proxy available that can monitor the 1433 port and pass the request thru to the correct SQL instance by name? Is this capability built into SQL server already? Thanks, Jim

  • Problem booting virtual machine after converting VMDK to VHD

    - by vg1890
    I used the VMWare VCenter Converter Standalone Client to convert a physical drive on my old PC to a virtual drive. The conversion worked fine and I ended up with a valid VMDK file. Next, I wanted to convert the VMDK to a VHD for use with Microsoft Virtual PC, since that's what I use on my new box. I used WinImage for the conversion and that worked fine, too. I can access the files from the virtual drive through WinImage. However, when I create a new virtual machine using Virtual PC and add the existing VHD file, the machine doesn't boot. The initial boot screen flashes with the amount of RAM and then the screen goes black. If I turn off the VM and reboot in safe mode I can see the drivers being loaded until eventually it gets to crcdisk.sys and hangs indefinitely. Any ideas how to fix this? I'm not opposed to starting over from scratch if there's another method to turn my physical machine into a Virtual PC VM. Thanks! EDIT - I should add that the virtual drive is a system boot drive and not a secondary drive. EDIT - I tried booting from the install CD and doing a repair. The result was that the system could not be repaired due to a "driver error."

  • Virtual Machines: What components should I upgrade to improve running virtual machines?

    - by joshsvoss
    at work I need to have one or sometimes two instances of a vmware virtual Windows 7 machine running on my real Windows 7 machine. The computer I'm using is Dell Precision 490 from 2009 I believe, possibly earlier. Running Windows 7 ultimate. Problems while running VM's: The entire computer slows down when a vmware instance is running. Pages take a while to react to a scroll, applications take forever to launch, and programs hang both in the virtual machines and on the real one. So, what components should I upgrade to improve this? I guess a more pointed question would be, which components will help the most? Possible options: Getting 8gb of RAM instead of 4gb new graphics card new processors? (Is that really an option?) My intuition tells me it will be a combination of the RAM and graphics card. There is also the possibility that an '09 tower just isn't cut out for vm's and our business should purchase a new tower.

  • Difference in performance: local machine VS amazon medium instance

  • How to remap IPs visible from local machine to IPs visible from a machine I have SSH access to?

    - by gooli
    I'm so far out of my depth I don't even know what to google for. There's a server I can connect to via SSH. Via that server I can access other server on its subnet via SSH. What I want to do is be able to access the machines that server has access to directly. Say the server IP is 192.168.7.7 and is the only one in the 192.168.x.x range I have access to. I'd like to configure things in such a way that when I to access say 192.168.7.100 on my machine, the connection will go through an SSH tunnel I open to 192.168.7.7 and out to 192.168.7.100. I would like this to work for any port if at all possible. I know I can set an HTTP proxy and even a SOCKS proxy, but I'm wondering is there is a way to actually remap some of the IP my machine sees to IP only visible from the remote machine. What would this configuration be called? IS this NAT, VPN, IP2IP or something else? How can I set up this on a Windows client box that connects via SSH to a Linux box? Sounds to me like I need to set up some kind of filtering on the network driver or possibly a virtual NIC, but I'm not sure where to go next.

When I click on an individual VM, and then click the camera image (or Ctrl+Shift+S) to take a snapshot, the snapshot process fails and VirtualBox gives the following error: Failed to create a snapshot of the virtual machine vmName. Details: Result Code: VBOX_E_IPRT_ERROR (0x80BB0005) This happens not only for one of my VMs, but all of them, if I try to take a snapshot of each one separately, one at a time. My computer is a Windows 7 machine. I have 200 GB free on my hard drive, and I see no reason why the error should occur. I can import VMs, run them, and clone then without any problems. Can anyone tell me what to do to fix the issue?

  • HAProxy "503 Service Unavailable" for webserver running on a KVM virtual machine

    - by Menda
    I'm setting up a server with KVM (IP 192.168.0.100) and I have created inside of it one virtual machine using network bridging at 192.168.0.194. This virtual machine has an nginx instance running, which I can access from the server or from any computer computer in the internal network just typing in the browser http://192.168.0.194. However, I try configure HAProxy in the same server that hosts KVM and looking the status page of HAProxy it always shows the virtual machine as "DOWN". If I try from the server http://localhost, it should be the same than if I go to http://192.168.0.194. My goal is to build a reverse proxy, but I tried this little example and won't work. What am I doing bad? This is my config file in the server: # /etc/haproxy/haproxy.cfg global maxconn 4096 user haproxy group haproxy daemon defaults log global mode http option httplog option dontlognull retries 3 option redispatch maxconn 2000 contimeout 5000 clitimeout 50000 srvtimeout 50000 listen ServerStatus *:8081 mode http stats enable stats auth haproxy:haproxy listen Server *:80 mode http balance roundrobin cookie JSESSIONID prefix option httpclose option forwardfor option httpchk HEAD /check.txt HTTP/1.0 server mv1 192.168.0.194:80 cookie A check Thanks.

  • What are the limitations of virtual machines?

    - by j-g-faustus
    I'm considering setting up a virtual machine running Windows, with Ubuntu 10.10 as the host OS, for those cases where I have a Windows-only program. I understand that using a VM will lose some performance, but are there other limitations to what the OS in a virtual machine can do compared to "running on bare metal"? For example: Can a VM play games, like Dragon Age Origins or Civilization V? (Possibly with poorer framerates and/or lower resolution, but does it play at all?) Can a VM rip DVD/Blue-ray using AnyDVD or similar Windows program? Can a VM handle new hardware that requires dedicated drivers, but the drivers are only available for the OS running inside the VM? (Ex. graphics card, digital camera, card reader for smart card authentication.) Is it possible to say anything about "general limitations" of VMs, or is this wholly dependent on the specific VM?
