• Why does Excel now give me already existing name range error on Copy Sheet?

  - by WilliamKF

  I've been working on a Microsoft Excel 2007 spreadsheet for several days. I'm working from a master template like sheet and copying it to a new sheet repeatedly. Up until today, this was happening with no issues. However, in the middle of today this suddenly changed and I do not know why. Now, whenever I try to copy a worksheet I get about ten dialogs, each one with a different name range object (shown below as 'XXXX') and I click yes for each one: A formula or sheet you want to move or copy contains the name 'XXXX', which already exists on the destination worksheet. Do you want to use this version of the name? To use the name as defined in destination sheet, click Yes. To rename the range referred to in the formula or worksheet, click No, and enter a new name in the Name Conflict dialog box. The name range objects refer to cells in the sheet. For example, E6 is called name range PRE on multiple sheets (and has been all along) and some of the formulas refer to PRE instead of $E$6. One of the 'XXXX' above is this PRE. These name ranges should only be resolved within the sheet within which they appear. This was not an issue before despite the same name range existing on multiple sheets before. I want to keep my name ranges. What could have changed in my spreadsheet to cause this change in behavior? I've gone back to prior sheets created this way and now they give the message too when copied. I tried a different computer and a different user and the same behavior is seen everywhere. I can only conclude something in the spreadsheet has changed. What could this be and how can I get back the old behavior whereby I can copy sheets with name ranges and not get any errors? Looking in the Name Manager I see that the name ranges being complained about show twice, once as scope Template and again as scope Workbook. If I delete the scope Template ones the error goes away on copy however, I get a bunch of #REF errors. If I delete the scope Workbook ones, all seems okay and the errors on copy go away too, so perhaps this is the answer, but I'm nervous about what effect this deletion will have and wonder how the Workbook ones came into existence in the first place. Will it be safe to just delete the Workbook name manager scoped entries and how might these have come into existence without my knowing it to begin with?

• Which linux distro to use? Hyper-V hosting.

  - by TomTom

  Not a linux geek I am looking for a recommendation which Linux distro to use for a hyper-v based hosting envfironment (so access to the enlightment part easily is important). I Would also love to have something that alloows me to split operating system read only files and user files easily without too much tinkering onto two discs, so that the boot disc can be read only. (reasoning: This would allow me to set up a read only disc that is shared between multiple server instances, with the server disc only containing basically the user files)

• Data Center Design and Preferences

  - by Warner

  When either selecting a data center as a co-location facility or designing a new one from scratch, what would your ideal specification be? Fundamentally, diversified power sources, multiple ISPs, redundant generators, UPS, cooling, and physical security are all desireable. What are the additional key requirements that someone might not consider on the first pass? What are the functional details someone might not consider during the initial high level design?

• How to log nginx vhost bandwidth?

  - by bwizzy

  I'm looking for a way to be able to track the bandwidth of multiple vhosts on an nginx web server. I'm guessing there is a way that I can set up the log files to output this information and then I can write a script to parse through the log files and add up the file sizes. If that is the case does anyone know the correct log format, and if there is already a script out there that does this?

• A way to extract layer sets from PSD files without Photoshop?

  - by chaddjohnson

  Are there any tools for (in order of preference) Mac, Linux, or Windows to extract images per layer set from a PSD file, without using Photoshop? I had a web designer send me a PSD file containing multiple pages, and each page is apparently in a layer set, and GIMP cannot handle these--it can't understand layer groupings. a command line tool, a rinky-dink Windows tool...anything will work, so long as it's free (preferable) or under $30, does not leave watermarks or anything of the sort, and works well.

• MacOS' dll equivalent

  - by kalaracey

  Hello all-- so, a DLL is similar to a folder, but it allows for multiple programs/executables to access it at once, thus conserving memory (I think). What is Mac's equivalent of a DLL? I was looking through the Google Chrome folders inside ~/Library/Application Support, and instead of the regular Windows Default.dll there was just a folder, "Default" as a regular file, with contents, I assume, would regularly be inside the DLL. Does the Mac equivalent provide the same function?

• Two Raid 1s in a single system?

  - by DebAtCQ

  I'm building a Raid array for the first time in my system and I have a question regarding having multiple Raid 1 arrays in a single Win 7 system. I'm a bit of an organizational freak with my data and I currently have two separate hard drives I want to mirror. The new motherboard I'm looking to buy supports Raid, so my question is this: a) can I have more than one Raid 1 array in a single system? b) would I have to buy a separate controller for the second array?

  - by Redconnection

  I would like to forward mail that gets sent root@localhost on multiple servers to our company admin account (e-mail is hosted on gmail) I have installed ssmtp on centos 5.5 via yum and configured it. i've also changed the last line in /etc/aliases to reflect where mail to root should go to. I've then tried sending mail to root - this gets delivered without a problem (mail -v root) I've also tried sending mail to root@localhost - this is not delivered to the specified gmail account.

• Are there any USB flash drives or SD cards which use RAID or redundant storage for additional reliability?

  - by Luke Dennis

  I'm looking to get a fault-tolerant USB flash drive, which saves data to multiple independent locations, whether using RAID or some other means to back up data. Has a product like this ever been created, or are my only options to hack something together? (By the way: I'm aware that RAID doesn't prevent data corruption from software or the file system. I'm just looking for something that can handle one of the memory sticks going dead.)

• Any consumer routers with Outgoing VPN support?

  - by Brian Lacy

  When I'm working at home, I need to be able to connect to three different outgoing VPNs, two of which happen to use the same internal IP addressing schemes (192.168.0.*). I also need a static address for my VirtualBox VM so I can connect to my testing web server. Are there any routers which will allow me to connect to multiple outgoing VPNs and assign different internal IP addresses through NAT? Is such a thing even possible, or are there alternate solutions available? Thanks!

• Excel 2010: dynamic update of drop down list based upon datasource validation worksheet changes

  - by hornetbzz

  I have one worksheet for setting up the data sources of multiple data validation lists. in other words, I'm using this worksheet to provide drop down lists to multiple other worksheets. I need to dynamically update all worksheets upon any of a single or several changes on the data source worksheet. I may understand this should come with event macro over the entire workbook. My question is how to achieve this keeping the "OFFSET" formula across the whole workbook ? Thx To support my question, I put the piece of code that I'm trying to get it working : Provided the following informations : I'm using such a formula for a pseudo dynamic update of the drop down lists, for example : =OFFSET(MyDataSourceSheet!$O$2;0;0;COUNTA(MyDataSourceSheet!O:O)-1) I looked into the pearson book event chapter but I'm too noob for this. I understand this macro and implemented it successfully as a test with the drop down list on the same worksheet as the data source. My point is that I don't know how to deploy this over a complete workbook. Macro related to the datasource worksheet : Option Explicit Private Sub Worksheet_Change(ByVal Target As Range) ' Macro to update all worksheets with drop down list referenced upon ' this data source worksheet, base on ref names Dim cell As Range Dim isect As Range Dim vOldValue As Variant, vNewValue As Variant Dim dvLists(1 To 6) As String 'data validation area Dim OneValidationListName As Variant dvLists(1) = "mylist1" dvLists(2) = "mylist2" dvLists(3) = "mylist3" dvLists(4) = "mylist4" dvLists(5) = "mylist5" dvLists(6) = "mylist6" On Error GoTo errorHandler For Each OneValidationListName In dvLists 'Set isect = Application.Intersect(Target, ThisWorkbook.Names("STEP").RefersToRange) Set isect = Application.Intersect(Target, ThisWorkbook.Names(OneValidationListName).RefersToRange) ' If a change occured in the source data sheet If Not isect Is Nothing Then ' Prevent infinite loops Application.EnableEvents = False ' Get previous value of this cell With Target vNewValue = .Value Application.Undo vOldValue = .Value .Value = vNewValue End With ' LOCAL dropdown lists : For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value If .Validation.Type = 3 And .Validation.Formula1 = "=" & OneValidationListName And .Value = vOldValue Then ' Debug ' MsgBox "Address: " & Target.Address ' Change the cell value cell.Value = vNewValue End If End With Next cell ' Call to other worksheets update macros Call Sheets(5).UpdateDropDownList(vOldValue, vNewValue) ' GoTo NowGetOut Application.EnableEvents = True End If Next OneValidationListName NowGetOut: Application.EnableEvents = True Exit Sub errorHandler: MsgBox "Err " & Err.Number & " : " & Err.Description Resume NowGetOut End Sub Macro UpdateDropDownList related to the destination worksheet : Sub UpdateDropDownList(Optional vOldValue As Variant, Optional vNewValue As Variant) ' Debug MsgBox "Received info for update : " & vNewValue ' For every cell with validation For Each cell In Me.UsedRange.SpecialCells(xlCellTypeAllValidation) With cell ' If it has list validation AND the validation formula matches AND the value is the old value ' If .Validation.Type = 3 And .Value = vOldValue Then If .Validation.Type = 3 And .Value = vOldValue Then ' Change the cell value cell.Value = vNewValue End If End With Next cell End Sub

• Custom settings with PHP on Nginx

  - by miki

  I have multiple websites setup using Nginx and Apache, but when I try to add a vhost based PHP directive using fastcgi_param PHP_VALUE , the value get added to all of my vhosts. Checking the value of the PHP parameter from PHP-CLI remain the actual one for whole server. e.g. I used fastcgi_param PHP_VALUE "memory_limit=512M" for a domain based nginx config, but it will be propagated to all domains on server. The 'php -i | grep memory_limit' show 128M though Not sure what I am missing

• How can I backup a remote dedicated Server 2008 to my own computer at home?

  - by Nishant

  My server 2008 has mysql databases, SQL Server databases, and multiple websites. How do I back this information up? I have setup the dedicated server to have two 300GB hard drives and they are both mirrored. I want to make sure that I have a backup somewhere else as well. If it's not my home server, I don't mind backing up somewhere else either but I want to make sure I can restore it completely in case of a failure.

• advise on pointing reporting service data sources

  - by pearcewg

  It's possible I am unable to resolve this because I have been spoiled in other DEV environments where I had one database server for each reporting server. I need some advise on how to point a single SQL Server reporting server to multiple database servers. These databases correspond to DEV, TEST and QA environments. The way the reporting is currently configured I am unable to toggle between environments gracefully. Any advise would be greatly appreciated.

• Reviews Cheyney Group Marketing: What accounting softwares are available in the market for small businesses?

  - by user225556

  Accounting is the language of business, and good accounting software can save you hundreds of hours at the business equivalent of Berlitz. There's no substitute for an accounting pro who knows the ins and outs of tax law, but today's desktop packages can help you with everything from routine bookkeeping to payroll, taxes, and planning. Each package also produces files that you can hand off to an accountant as needed. Small-business managers have more accounting software options than ever, including subscription Web-based options that don't require their users to install or update software. Many businesses, however--including those that need to track large inventories or client databases, and those that prefer not to entrust their data to the cloud--may be happier with a desktop tool. We looked at three general-purpose, small-business accounting packages: Acclivity AccountEdgePro 2012 (both the product and the company were previously called MYOB), Intuit QuickBooks Premier 2012, and Sage's Sage 50 Complete 2013 (the successor to Peachtree Complete). All three packages offer a solid array of tools for tracking income and expenses, invoicing, managing payroll, and creating reports. These full-featured and highly mature programs don't come cheap. Acclivity AccountEdge Pro, at $299, is the least expensive; and prices climb if you opt to use common time-saving add-ons such as payroll services, or if you add licenses for multiple user accounts. All three are solid on the basics, but they have distinct differences in style and focus. The more you know about your accounting requirements, the more closely you'll want to look at the software you're thinking of buying. Sage 50 Complete should appeal most to people who understand the fine points of accounting and can use the product's many customization features (especially for businesses that manage inventory). QuickBooks works hard to appeal to newbies who need only the basics and might be intimidated by the level of detail and technical language exposed in the other two packages. At the same time, it also has a slew of third-party add-ons that meet specific needs and greatly expand its capabilities. AccountEdge Pro balances accessibility with a strong feature set at an affordable price. It's especially suitable for businesses that need to provide simultaneous access to multiple users.

• Burn 30GB zip file to DVD

  - by Joel Coehoorn

  I have a zip 30GB zip file containing an archive a digital materials available in the school library that I want to burn to dvd. Of course, 30Gb is far too large for a single dvd and the content is already zipped. I'm open to ideas, but leaning towards suggestions that will help me automatically spread the file over multiple dvds, including a simple program to stitch it back together again later.
