• Is it possible to synchronize with Microsoft Sync Framework through FTP-transfers?

  - by Christian80

  I'm looking at synchronize methods between two databases and found Microsoft Sync Framework recently. I've been trying to investigate if it suits my needs. My scenario is the following: Two SQL-databases located in different geographical parts. The remote database can go without internet connection for days at times and for some locations the only means of communicating is with ftp transfers to the main server. So my question is: Is it possible to sync between two servers and send the sync-information and data through a ftp-server?

• Is it possible to copy a set of files, but automatically skip if file already exists?

  - by awe

  I know that the copy command has an option to automatically replace a file if it already exists, but I want to know if it is a way to copy the files only if they not already exist (/Y). I do not know the actual file names in the batch code, as I copy from the source using wildcards in the copy command: copy *.zip c:\destination The reason I want this instead of automatic overwrite is that the files are large, and to skip existing would save a lot of execution time.

• Is it possible to compute the minimum of three numbers by using two comparisons at the same time?

  - by Milo Hou

  I've been trying to think up of some way that I could do two comparisons at the same time to find the greatest/least of three numbers. Arithmetic operations on them are considered "free" in this case. That is to say, the classical way of finding the greater of two, and then comparing it to the third number isn't valid in this case because one comparison depends on the result of the other. Is it possible to use two comparisons where this isn't the case? I was thinking maybe comparing the differences of the numbers somehow or their products or something, but came up with nothing. Just to reemphasize, two comparisons are still done, just that neither comparison relies on the result of the other comparison. EDIT: what about: boolA = A^2 + B^2 < C^2 boolB = A > B if boolA then max=C else if boolB then max=A else max=B

• Is it possible to create a sub window which will not deactivate the parent?

  - by Bob

  Normally when creating a sub window (WS_POPUP), the child window will become activate and the parent will become deactivated. However, with menus, both remain active. At least I am assuming the menu is active, it at least has focus. Example: Click on the file menu in notepad, the menu appears, yet the notepad window still looks active. Is it possible to mirror this behavior with either a window style or responding to a particular message? Thanks Another example: Combo boxes seem to show a subwindow, yet do not deactivate the window. And you can click on that subwindow, while still maintaining an activate main window. Any ideas on how to grab the class /style of that window?

• Is it possible to live-boot VirtualBox from a USB flash drive?

  - by bw.

  To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

• MySQL : select/join on strings as fieldnames - is this possible?

  - by Dylan

  I can retrieve all column names from table 'categories' with : SELECT col.column_name FROM information_schema.columns AS col WHERE col.table_schema= database() and col.table_name = "categories" This produces a resultset like this : column_name ----------------- categoryID name description I can retrieve all values for a specific category with : SELECT * FROM categories AS c WHERE c.categoryID=12345 this results in a resultset like this: categoryID | name | description ------------------------------------------------ 12345 | test | this is a test Now I would like to get some kind of join of above selects to get a resultset that looks something like this : fieldname | value ---------------------------------------- categoryID | 12345 name | test description | this is a test Does anyone know if this is possible ? Can you do a join on strings that come from another select ?? The reason for this is that I'm writing a universal stored procedure that outputs all fields + their values from a table, without knowing what fields there are in the table. (The tablename is given in a parameter)

• SQL Server on VMWare - is transaction log corruption possible?

  - by demp

  Scenario: SQL Server 2005 or 2008, Windows 2008 OS. Running in a VM hosted on VMWare ESX server. Is there any known issue with VMWare when it caches pass-through write request and it never reaches the disk, while SQL Server "thinks" that write actually happened? This may lead to transaction log corruption in case of power failure or VM reboot. Just overheard the conversation but couldn't find it in relation to ESX.

• Is it possible to autocomplete fields in Sharepoint with user info?

  - by Antoine

  Hi, I'm in charge of a Sharepoint collection, and a user asks this. Is it possible that when a user creates an item, some fields are automatically filled with some info, such as email address and location? Authentication uses Active Directory, so every user is identified when using Sharepoint. The only issue is that, being in a big corporate company, I don't have any access to the server, so it must be feasible through configuration of said site/list or using Sharepoint Designer, but I can't and won't be allowed to deploy anything server side. Any idea?

• Is it possible to run a hidden console application from a Windows service?

  - by norgepaul

  I've written a server in Delphi 2010 that needs to launch a console application every now and again to back up a database. The console application can send log information to the console window, but it is not required. This works fine when running as an application, but when run as a service I get an access violation when launching the console application. This is the case even if I launch it hidden (SW_HIDE). Is it possible to launch a hidden console application from a Windows service? The solution needs to work on XP, Vista and Windows 7.

• Is it possible to change the file path of the video using javascript?

  - by Manish

  I have an object tag in a HTML file: <object classid="clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95"> <param name="FileName" value="../ABC/WildLife.wmv" id="mediaPlayerFile"> <param name="AutoStart" value="false" /> </object> I want to change the filename using javascript. What I have so far is this: <script type="text/javascript"> function disp_current_directory() { var val = document.getElementById('mediaPlayerFile'); val.attributes['value'].value = "D:\XYZ\WildLife.wmv"; } </script> But this doesn't work. :( Is it possible? If yes, how?

• Is it possible to prevent iPhone/iPad orientation changing in the browser?

  - by BoomShaka

  I've seen similar questions on this issue, but they are related to native apps. I build web apps for the iPhone/iPad that run in the browser (Safari). I was wondering if there is a way to prevent orientation change in the browser, perhaps via some meta tag. I know of the viewport meta tag which allows you to specify scale and zooming capabilities, so figured maybe there is something similar for orientation. I doubt it is possible, but I thought I'd just pop a question on here to see.

• Is it possible to have Sharepoint display a Shared Exchange calendar?

  - by BejeweledOne

  The reason for this is that we use Live meeting heavily. While you can create a live meeting in a SharePoint calendar, because it is just a list, the links do not work if accessed through Sharepoint. We would need to have these links work properly. We use MOSS 2007 and Exchange/Outlook 2007

• Is it possible to create a jdbc connection without a password (using postgresql 'trust')?

  - by mojones

  I am using jdbc to connect to a postgresql database in a java application (actually the app is written in Groovy). I have postgresql set up to use the 'trust' authentication method. Is it possible to open a jdbc connection without specifying a password? When I try to use the normal constructor with a blank password, it fails with Exception in thread "Thread-2" org.postgresql.util.PSQLException: FATAL: password authentication failed for user "myuser" Even though, from the command line, this works fine psql -U myuser mydatabase Welcome to psql 8.3.5, the PostgreSQL interactive terminal. Type: \copyright for distribution terms \h for help with SQL commands \? for help with psql commands \g or terminate with semicolon to execute query \q to quit

• Stopped windows firewall service during ICS, how is this possible?

  - by insipid

  Although windows firewall is required to be on when you "start" Internet Connection Sharing, you can stop the WF service with MMC. When done a client can still use the host machines internet. The firewall had port 80/http blocked, and now it is open for incoming traffic. However other ports used by applications on the host and client which communicate with each other still seem to be blocked. Can anybody explain what might be happening here? Doesn't ICS need windows firewall for NAT? Note: I am not actually seeing anything in the firewall logs after stopping the service, but even packets sent localhost on the host machine never arriving on these other random ports.

• Learn as much as possible about the setup behind a website.

  - by carrier

  Let's say I'm in the process of planning the setup of a website. I study similar sites that offer similar services or might receive similar traffic model. Is there a way to determine a bit the kind of setup, software and/or hardware. Some things are obvious. If I see .php or .jsp then I already know a bit. But any ideas on how to decipher more? Maybe where the site is hosted, hardware, platforms...

• Possible to have empty values with Html For Helpers such as Html.TextBoxFor()?

  - by chobo2

  Hi Is it possible to have to make a html for helper in asp.net mvc 2.0 have a default value of "empty string" Like if I do this Html.TextBoxFor( u => u.ProductName) would render to <input id ="ProductName" name="ProdcutName" type="text" value="Jim" /> Now I don't want the textbox to display jim. I want it to display nothing. <input id ="ProductName" name="ProdcutName" type="text" value="" /> I tried to do this Html.TextBoxFor( u => u.ProductName, new { @value = " "}) but that seems to do nothing. So how can I do this. I hope you can do something like this otherwise I think these new helpers have a great flaw since now I need to use like javascript to remove them since I hardly ever want a default value in the textbox especially when I have a label right beside the textbox saying what it is.

• Algorithm: Removing as few elements as possible from a set in order to enforce no subsets.

  - by phimuemue

  Hello, I got a problem which I do not know how to solve: I have a set of sets A = {A_1, A_2, ..., A_n} and I have a set B. The target now is to remove as few elements as possible from B (creating B'), such that, after removing the elements for all 1 <= i <= n, A_i is not a subset of B'. For example, if we have A_1 = {1,2}, A_2 = {1,3,4}, A_3={2,5}, and B={1,2,3,4,5}, we could e.g. remove 1 and 2 from B (that would yield B'={3,4,5}, which is not a superset of one of the A_i). Does anybody know an algorithm for determining the (minimal number of) elements to be removed?

• What are possible results/side effects if replication between DC's in a Windows domain is unable to occur?

  - by hydroparadise

  There's plenty of administration literature out there how to properly manage Windows servers. But in dealing with real life, things don't always occur like you want them to. In Microsoft's Windows Server 2003 Administrator's Companion, out of 1400+ pages, theres only one page that I could find when it comes up setting up additional domain controlers. They make it sound seemless and don't reveal a whole lot on what happens if "peer" DC's are unable to replicate. Down to the specific issue at hand, we had a DC go down about a month ago due to a bad RAID controller. There was nothing critical that waranted imediate attention, so bringing it back up got put on the back burner. A month later, we get the DC back up and running and everyting seemed ok. The next day, nobody is able to logon complaining that the "user does not exist" or "unable to establish a trust relationship". Knowing that I had just put the downed DC back on the network, I immediately took it back off the network and had everybody restart the workstations. After that, exchange was fine, shares became available, and everybody was able to log in. After doing some event log swimming, it would appear that everything started due to replication issues on the SYSVOL. I've read where you can force replication, but that would mean putting it back on the network. I am afraid to put the DC back on the network in fear that something else could go wrong. So, what other issues could one expect to run into where two DC's are unreplicated for over a month?

• Is it possible to create a self-signed intermediate CA for ssl?

  - by limilaw

  I am trying to create my own SSL hierarchy like: MyRootCA --MyIntermediateCA ----MyCert I have installed MyRootCA and MyIntermediateCA, but windows points out that MyIntermediateCA doesn't have the right to issue certs. Therefore it invalidates MyCert. i.stack.imgur.com/XDtXp.png i.stack.imgur.com/rZNQZ.png I am using sign.sh from mod_ssl package, which utilizes openssl ca command. I wonder if there is any parameter/option that grants MyIntermediateCA the right to issue sublevel certs?

• Is it possible to use an incremental value within a variable name whilst declaring it within a loop?

  - by Jack

  Hi, I'm creating function which will read different XML files each time that will contain different amounts of the same nodes. I have already created a loop which stores the ID of each node into an array, and now I want to create variables for each array member which store attributes of the node with each ID. Because the number of nodes will be different for every XML document my function reads, I cannot manually assign variables for the attributes of each node ID not knowing how many to assign, so I have created a loop which runs specific to the number of items I have stored in the array. Inside this loop I was hoping to have something like: for (i=0; i<array.length; i++) { var ID + i + width = exampleheight var ID + i + height = exampleheight } I know this doesn't work, but was trying to outline what I am looking to find out. Is it possible to use some kind of variable or random number when declaring a variable?

• In Process Explorer is it possible change scaling of activity graph the be able to further analyse graph?

  - by therobyouknow

  Is there any way to zoom in, in the System Internals Process Explorer graph? Background I'm trying to work out why my PC freezes/locks up for about a second (the pointer does not move) every so often. This has only been happening for the last 2 days. There is a very narrow spike associated with the freeze, but it's hard to hover over it an analyse what is causing it. My PC spec: ThinkPad X201S 1440x900 i7 2.0GHz 8Gb RAM, 256GB Samsung 840Pro SSD, Windows 8.1 Pro 64bit CalDigit USB 3.0 ExpressCard 34, Ultrabase X200 with DisplayPort to HDMI

• In Linux, is it possible to get a listing of drives' disk space usage that also shows volume labels?

  - by DavidH

  I know about df, of course, but df does not output volume labels. I have 5 USB hard drives plugged into my NAS box, and would love to know which is which.

• Is it possible to supply the jQuery Validation plugin with a rules object?

  - by ethagnawl

  I took the rules that I'd been using to validate my form and broke them out into a JSON object, hoping to use the same set of rules for client/server validation. So, where I had: $(document.getElementById('new_listing_form')).validate({ rules: { apt: { required: true } } }); I'm attempting to use: var rules_obj = { apt: { required: true } }; $(document.getElementById('new_listing_form')).validate({ rules: rules_obj }); ... and the form is not being validated. Does anyone know if this is possible?

• Is it possible to view the contents of an underlying NFS mount without unmounting the NFS content?

  - by Brent

  I have a shared directory on a server - let's call it /home/shared - which is mounted with content from another server via nfs. When it is unmounted /home/shared is supposed to be empty - however, running du -x on the directory indicates that it is not empty. I cannot unmount the NFS content to inspect the mount point, since it is in use by others. Is there any way that I can view/edit the contents of the actual mount point (not the NFS content) while leaving the NFS content mounted for others to use?
