• Are there any online database schema drawing tools?

  - by Pure.Krome

  Hi folks, i wish to draw up some database schemas. Eg, table 1 has zero to many rows in table 2, etc. It's purely for visual purposes (eg. no sql code, etc). Are there any online tools / website that offer this? (please don't say: Use Sql Server Database Diagrams, print screen, upload to image hosting service). thanks :) EDIT: Please take note of the keyword - ONLINE. I don't want any desktop solutions (because I already have one of these).

• Windows 7 Media Center suddenly Jerky..

  - by Kris Erickson

  Media Center in Windows 7 has been running great for me for the past few months since I switched to Windows 7. I can watch HD content on my Xbox, and I have had very few issues with it (occasionally it has locked up on the Xbox, but restarting the Xbox usually fixes that). All of a sudden it has gotten jerky, SD content playing on my computer (not even streaming to the Xbox) is Jerky. VLC and Windows Media Player play the same content perfectly, it is just when it is playing in Windows Media Center (whether streaming or not). Any ideas what could be the cause of this? And yes I have reboot several times...

• Cannot get Windows snipping tool to auto run with AutoHotKey

  - by jasondavis

  I am trying to get Windows 7 sniping tool to run when I hit my PRINTSCREEN keyboard button with AUTOHOTKEY. I have been unsuccessful so far though. Here is what I have for the AutoHotKey script. I have tried this PRINTSCREEN::Run, c:\windows\system32\SnippingTool.exe and this PRINTSCREEN::Run, SnippingTool.exe and this PRINTSCREEN::Run, SnippingTool And all those give me this error when I hit the PRINTSCREEN button... It basicly says it cannot find the file, however the file path seems to be correct, I can copy paste it into a window and it opens the snipping tool, any ideas why it will not work? Here is the full code to my AHK file... ; ; AutoHotkey Version: 1.x ; Language: English ; Platform: Win7 ; Author: Jason Davis <friendproject@> ; ; Script Function: ; Template script (you can customize this template by editing "ShellNew\Template.ahk" in your Windows folder) ; #NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases. SendMode Input ; Recommended for new scripts due to its superior speed and reliability. SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory. /* PRINTSCREEN = Will run Windows 7 snipping tool */ PRINTSCREEN::Run, c:\windows\system32\SnippingTool.exe return

• Upgrading Windows 8 Consumer Preview to Release Preview

  - by user1407016

  I currently have my main hard drive split into two partitions. One being Windows 7 with about 600 GB of memory, the other Windows 8 Consumer Preview with about 50 GB. As you can guess it is set up for a dual boot. Today while looking up how to get the C# Facebook SDK for Metro apps I learned about the Release Preview being released. I was wondering: How do I go about getting rid of Windows 8 Consumer Preview and replacing it with the Release Preview? I know i can't just wipe it off my second partition because the dual boot uses Windows 8 to choose the operating system to boot.

• Windows zip error: Windows cannot complete the extraction. The destination file could not be created

  - by Snake Eyes

  I have a strange error in Windows 7 when I want to execute/open a file inside ZIP archive. I have two files: File1.dwg File2.dwg The archive is not corrupted ( I checked with 7zip utility ) When I double click on the any file inside ZIP (I opened ZIP with Windows Explorer), the error occured: Ok. If I open zip file with 7-zip or WinRAR every file could be opened(executed) without error and the AutoCAD is opened to see the dwg content. Why in Windows ZIP ? What points have I to see to manage/remove this error ? Thank you. UPDATE If I click Extract all from Windows ZIP, the error occured as unspecified error:

• Caching web page data, Database or File

  - by Mahdi

  I am creating an RSS reader application that requests the RSS from my server. I mean, the RSS is first downloaded to my server, then application downloads it from my server. I want to create RSS cache for this. And for example, each RSS would be refreshed every 1 minute. So, If 10 users request RSS of example.com in 1 minute, my server will download it only for the first time, and in other 9 requests, RSS will be loaded from cache. My question is, Should I use a Database (MSSQL) for this purpose? or I should use files? I have no limit in Database size nor in file size... EDIT: I'm using ASP.NET for the server.

• Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

  - by ben

  I have an odd error that doesn't seem to fit in with any of the other odd Windows 7 x64 USB errors that have been kicked up on Google. Here we go: Uninstalled Tortoise SVN and clicked restart computer. My machine had been up for around 28 days On reboot my mouse and keyboard failed to work anymore, couldn't log in. Tried every USB port I have on my Dell 390 and the ports on my Dell 19's, nothing worked. They had power but Windows would not respond when I manipulated the keyboard/mouse. Rebooted my computer and pressed F2 to get into bios, my keyboard is working fine in bios. Keyboard and mouse work fine on other computers when using USB. Found adapters for keyboard and mouse to convert from USB to PS/2 ports, works fine. I'm actually typing this question on the same keyboard, same computer, just using PS/2 ports for my mouse and keyboard. It appears to be a Windows 7 x64 issue. Other things I have tried: Multiple other mice and keyboards, iphone, all with no luck. Each one gets power, but Windows never tries to install drivers or sees that they are connected. Uninstall and reinstall all USB drivers. Drives uninstall and reinstall fine and report no errors in Control Panel. In Power Management I disallow Windows from turning off USB ports to save power Installed the latest nVidia drivers for my graphics card, no change. Anyplace else I can look/try? Thanks!

• WEIRD netstat behavior on Windows XP re: www.partypoker.com

  - by tbone

  I really don't know if this is the right place to ask this, but I would really appreciate if someone that is more savvy on Windows XP (Professional) could help me out. For background, I am a 10+ years programmer, so I'm not a total idiot, but I am far from an expert on TCP/IP, etc, and this has me totally confused. When I do a netstat (on Windows XP) I seem to always get a huge amount of www.partypoker.com connections and I can't figure out where they are coming from. A netstat -o shows me that some are coming from PID xxx, which is firefox, but if I kill it, the connections still remain. Some are coming from PID 0, which makes no sense to me. SECOND PROBLEM: One would think you could edit the C:\WINDOWS\system32\drivers\etc\hosts file to block this, but it seems like my machine is ignoring the hosts file! (I have tried with the DNS client service both enabled and disabled, same result). So I just rebooted, killed all my normal programs, and I can't seem to reproduce the problem. If I was a paranoid person, I would think there was some sort of an intelligent trojan running. I am running Windows XP Pro, Kaspersky Antivirus, ccCleaner, and am fully up to date on Windows Update. What gives???? So, I guess my questions are: 1. Is anyone else seeing these wird connections to partypoker.com? 2. Why isn't my hosts filter working? 3. Is there some utility I can run to find out whats happening? I've tried autoruns.exe from sysinternals but don't see anything interesting. Am I the only one with this problem? If there are any additional things you need me to run, let me know.

• Windows XP Disc: corrupt or not corrupt?

  - by Wesley

  Hi all, I just finished one of my builds and am trying to install Windows XP onto it. Here are the specs beforehand... Intel Pentium 4 Northwood 2.4 GHz (512KB L2, 533MHz FSB) QDI Superb 4 Motherboard 2x 1GB PC3200 DDR RAM Seagate 80GB IDE HDD Bestec 250W PSU 16MB NVIDIA TNT2 Pro Samsung DVD-ROM USB 2.0 PCI Card Generic PCI Modem The issue right now is that when I'm running through the Windows Setup from my XP Pro SP3 disc, partway through the setup says that a random file on the disc is corrupt and the computer needs to be restarted. Every time I tried booting it up, a different file was noted as corrupt. However, I tested the same disc on another computer and the Windows XP disc ran to the end of the setup screen without error. I tried this on another computer and the same thing. What could possibly be happening on this one build to cause it errors during the Windows Setup? Thanks in advance.

• PHP 2D Array to MySQL Database

  - by Ashley Ward

  I have a PHP 2D array, many keys, each with one value, I need to put this into a MySQL database. The database has 8 fields. Eg. Field1, Field2, Field3, etc. I am trying to ensure value1 => field1, value2 =>field2, value3 => field3 and so on, when one record is full (i.e. after 8 values) a new record should be created for the next 8 values and so on. I am aware that the 1st, 9th, 17th, 26th values etc, will need an insert statement and the intermediate values will be an update statement. What is the best way of going about this?

• Windows 7 Printing to a network printer

  - by JohnyV

  We have a 2008 server as our print server. Clients that use windows xp with a logon script to map have no problems printing. When I test printing to a network printer on a windows 7 machine it works fine up to a few machines as soon As i get 12-15 workstations trying to print, when they log in they get the yellow exclamation mark and needs troubleshooting against the printer name. It is being deploy by group policy. I have tried to deploy it by group policy also by group policy preferences and by using a script and i get the same error whatever i try. Does anyone have any suggestions to try and troubleshoot? Once again Windows xp clients have no issues printing at all. It is only windows 7 clients. Thanks

• Windows 7 won't show SATA Hard Drive in My Computer

  - by Darth

  I have clean install of Windows 7 x64 with two SATA hard drives. When I open My Computer, I can see only the drive where Windows are installed (and all partitions), but I don't see the other one. When I go to disk manager, I can see that both drives are detected and the one that I don't see in My Computer is also marked as Primary, but when I right click, the Open and Browse are gray. I also checked drives with gparted on live Ubuntu and they both seem to work correctly, the second drive wasn't marked hidden or anything else. Before installing Windows 7, I had Windows XP, where both drives worked properly.

• Representing a schedule in a database

  - by David Pfeffer

  I have the interesting problem of representing complex schedule data in a database. I need to be able to represent the entirety of what the iCalendar (ics) format can represent, but in my database. I don't care about insertion efficiency but query efficiency is critical. The operation I will be doing most often is providing either a single date/time or a date/time range, and trying to determine if the defined schedule matches any part of the date/time range. Other operations can be slower. For those unfamiliar, ics allows representation of a single event or a reoccuring event based on multiple times per day, days of the week, week of a month, month, year, or some combination of those. For example, the third Thursday in November, or the 25th of December, or every two weeks starting November 2nd and continuing until September the following year. Any suggestions?

• PHP mySQL database check

  - by kielie

  Hi guys, I am having endless troubles with duplicate entries, so I need to check the database, and if a user has already entered that day, their entry will not be submitted and they will be redirected to a landing page that tells them they have already entered that day, and that they may only enter again tomorrow. The field I would like to check is the id_number field in the database, since each user has a unique id number, so basically, if a user with the same id number submitted on the same date they should be redirected to a landing page, how would I go about doing this? I am still new to a lot of this, so please be forgiving. Thanx in advance.

• Creating database desktop application with data manipulation in Netbeans using Java Persistence

  - by Lulu

  It's my first time to use Persistence in developing a Java program because I usually connect via JDBC. I read that for large amounts of data, it is best to use persistence. I tried playing with the CRUD example of Netbeans. It's not very helpful thought because it only connects to the DB and allows addition and deletion of records. I need something that will allow me to manipulate the data like if the value from column C1 of table T1 is such, it will retrieve data from table t2. In short, I need to apply conditions before knowing what to retrieve exactly. The example in CRUD example already has a specific table to retrieve and only acts like a database manager. How is it possible to retrieve a specific item first then from this, will determine the next steps to be done. I'm also using embedded JavaDB/Derby as my database (also my first time to use because I usually use remote mysql)

• Suppressing / Accepting warning windows automatically in commands executed through batch file

  - by David Somach

  I am automating the uninstall of IE9 through executing the command in these instructions inside a batch file: http://answers.microsoft.com/en-us/ie/forum/ie9-windows_7/how-to-uninstall-ie9-beta-64-bit-it-is-not-in-the/863d8f3d-c4ab-43e6-9d57-e163ea3baddd The instructions say to run the command twice. The first time the command runs, I get the following error window (3 times): "Windows Package Manager Operation failed with 0x80070005 Access id denied." I click OK for each of these windows, and the rest of the script runs fine and IE8 is usable after restart. Is there a way to suppress these windows? I want this to be fully automated and these windows block the script until the user presses "OK".

• Automate creation of Windows startup script?

  - by Niten

  Is there a good way to automate installing local startup (rather than login) scripts in Windows XP and Windows 7, via the command line, WMI, or otherwise (even COM or Win32 if it comes to that)? I need to setup a local startup script on a large number of computers, and unfortunately, Active Directory is absolutely not an option. I would like to write a script or small program that I can run on each computer to perform the startup script installation in order to save myself a lot of error-prone point-and-click manual labor. I see that when one uses gpedit.msc to create a local startup script, information about the script gets stored in the registry here: HKLM\Software\Policies\Microsoft\Windows\System\Scripts\Startup However, if you create such a script and then delete its registry key, the script will remain listed in the local Group Policy editor; as is so often the case in Windows, apparently there is more going on there than meets the eye. This leads me to question whether it's safe to manually add subkeys for new startup scripts here (I wouldn't want my script to be overwritten by later changes made using the local Group Policy editor, for instance)... Another option that's occurred to me is to create an item in the Task Scheduler configured to run at system startup. However, my concerns there are twofold: Can this be automated any more easily? For instance, the at command doesn't appear to let you schedule a task for system startup, and WMI's Win32_ScheduledJob interface looks unreliable (it fails to show any of my currently scheduled tasks, for one thing). Would I be able to prevent users from logging in until the scheduled startup task is completed, as can be done with "normal" Windows startup scripts? Thanks in advance for any suggestions, I've been banging my head against this one for a bit...

• Windows 7: enabling navigation of subfolders in pinned Start Menu folders

  - by AspNyc

  I'm just about to move from Windows XP to Windows 7, and I'm struggling with some of the interface changes. In XP, I was able to throw a folder intoC:\Documents and Settings\username\Start Menuand have it appear on the Start Menu, complete with the ability to navigate through subfolders. I've figured out how to pin a folder onto the Start Menu in Windows 7, which required a registry hack. However, I am unable to view the subfolders of the pinned folder without opening a new Windows Explorer window. Is there any way to replicate the old XP behavior I'm used to? I'd like to be only a single click away from these handful of application links and folders, since I use them all the time throughout the day.

• Simple database design and LINQ

  - by Anders Svensson

  I have very little experience designing databases, and now I want to create a very simple database that does the same thing I have previously had in xml. Here's the xml: <services> <service type="writing"> <small>125</small> <medium>100</medium> <large>60</large> <xlarge>30</xlarge> </service> <service type="analysis"> <small>56</small> <medium>104</medium> <large>200</large> <xlarge>250</xlarge> </service> </services> Now, I wanted to create the same thing in a SQL database, and started doing this ( hope this formats ok, but you'll get the gist, four columns and two rows): > ServiceType Small Medium Large > > Writing 125 100 60 > > Analysis 56 104 200 This didn't work too well, since I then wanted to use LINQ to select, say, the Large value for Writing (60). But I couldn't use LINQ for this (as far as I know) and use a variable for the size (see parameters in the method below). I could only do that if I had a column like "Size" where Small, Medium, and Large would be the values. But that doesn't feel right either, because then I would get several rows with ServiceType = Writing (3 in this case, one for each size), and the same for Analysis. And if I were to add more servicetypes I would have to do the same. Simply repetitive... Is there any smart way to do this using relationships or something? Using the second design above (although not good), I could use the following LINQ to select a value with parameters sent to the method: protected int GetHourRateDB(string serviceType, Size size) { CalculatorLinqDataContext context = new CalculatorLinqDataContext(); var data = (from calculatorData in context.CalculatorDatas where calculatorData.Service == serviceType && calculatorData.Size == size.ToString() select calculatorData).Single(); return data.Hours; } But if there is another better design, could you please also describe how to do the same selection using LINQ with that design? Please keep in mind that I am a rookie at database design, so please be as explicit and pedagogical as possible :-) Thanks! Anders

• Getting 0x80070043 error when accessing Samba share from Windows 7

  - by FelixM

  I created a Samba share on my new Ubuntu 10.04 machine. When I try to access it from a Windows 7 client, I get network error 0x80070043 (The network path not found). However, I get this error when I click on the share in the Windows Explorer, so it seems that Windows does find the path. I already enabled NTLMv1, disabled 128bit security and made sure that NetBIOS is running. I briefly disabled the Windows firewall, it didn't make a difference. What could be the problem?

• Thoughts/Input about Database Design for a CMS

  - by dallasclark

  I'm just about to expand the functionality of our own CMS but was thinking of restructuring the database to make it simpler to add/edit data types and values. Currently, the CMS is quite flat - the CMS requires a field in the database for every type of stored value (manually created). The first option that comes to mind is simply a table which keeps the data types (ie: Address 1, Suburb, Email Address etc) and another table which holds values for each of these data types. Just like how Wordpress keeps values in the 'options' table, PHP serialize would be used to store an array of values. The second option is how Drupal works, the CMS creates tables for every data type. Unlike Wordpress, this can be a bit of an overkill but really useful for SQL queries when ordering and grouping by a particular value. What's everyone's thoughts?

• Does Windows 7 allow advanced skinning like Windows XP?

  - by Vilx-

  The Windows 7 Aero interface looks great, but after looking at it for months it gets boring. So I was wondering - is it possible to create advanced skins for Windows 7 that use full Aero capabilities but are redesigned from ground up, including common controls, animations, effects, etc? Windows XP allowed that, although only with a patched uxtheme.dll. Or do you have to implement a custom shell for that?
