  • Starting VM as an executable with as low overhead as possible

    - by Robert Koritnik
    Is there a solution to create a virtual machine and start it by having an executable file, that will start the machine? If possible to start as quickly as possible. Strange situation? Not at all. Read on... Real life scenario Since we can't have domain controller on a non-server OS it would be nice to have domain controller in an as thin as possible machine (possibly Samba or similar because we'd like to make it startup as quickly as possible - in a matter of a few seconds) packed in a single executable. We could then configure our non-server OS to run the executable when it starts and before user logs in. This would make it possible to login into a domain.

  • Samba port forwarding?

    - by Robert
    Here's my situation: On my network, most of the clients are on an outside router. Router 1 192.168.1.1 | | - Client | Router 2 192.168.1.2 to router 1, | 192.168.2.1 to clients within | Samba server - 192.168.2.25 I cannot figure out how to get clients under router 1 to access the Samba shares in router 2. I have forwarded ports 139 and 445 to the appropriate machine in router 2 but machines in router 1 still cannot access the server. How would I set this up?

  • Apache on CentOS 5.9 VM serves my optimized images corrupted (but my Mac doesn't)

    - by Robert K
    I'm using a Vagrant VM to mirror the client's environment as closely as I can. As part of our build process we do no optimization of assets early on; that comes as we're ready to take a site live. Needless to say, this issue is beginning to worry me as we need to take the site live very soon. I use ImageOptim to automate optimization of image assets, which runs a whole series of tools (Zopfli, PNGOUT, OptiPNG, AdvPNG, PNGCrush). I always set the optimizations to their maximum setting. After optimization, my PNGs start looking like this: What's weird is, if I serve the same file through my Mac's copy of Apache, not through Vagrant, the image loads fine. In fact, the only time it's ever corrupt like this is when the image is served from the Vagrant VM and its install of Drupal. All optimized JPEGs display only the first ~20% of the image. And PNGs, depending on the image, may show either a portion or the "progressive"-style corruption below. The browser itself makes no difference, the same browser will serve an uncorrupted image from my Mac's Apache instance and a corrupt image from the VM. When I disable all PNG optimizations except PNGCrush, and the removal of the PNG metadata, the image is served corrupted. I'm optimizing JPEG images with JPEGmini. The server is running CentOS 5.9, Apache 2.2.3-85, PHP 5.3.3, and Drupal 7. As best as I can tell the error lies somewhere within the VM, either with Apache or with (perhaps) the network stack. Seems like the tools that optimize the compression of the PNGs and JPEGs are what trigger this error. I've already determined that the .htaccess file isn't interfering with how the images load. What should I try to troubleshoot this?

  • Force Pinned taskbar items to be "icon only" all the time in Windows 7

    - by Robert
    By default (at least in my installation), pinned items on the taskbar will be "icon only" when they have no active windows, but when there are active window, the icon expanded to include text (typically some portion of the title text). I'm looking for a way to either: A (preferred option): For any single pinned item, force this pinned item to always display as just the icon even if it has active windows. OR B (acceptable option): Force ALL pinned items to always display as icon only in the taskbar

  • Multiple network interfaces and UDP packets distribution

    - by Robert Kubrick
    I have a Linux server with 2 1Gb network interfaces eth1 and eth2. If I start 2 clients listening to the same multicast address and each client connects through a different NIC (say client 1 listens to the multicast through eth1 and client 2 through eth2), then client 2 gets duplicate UDP packets. If both clients use the same interface eth1 on the other hand, both clients work fine. I have already tried to set arp_filter and proxy_arp to 1 (arp flux issue) but it hasn't solved the issue. Is this a Linux kernel problem? Or is there another way to setup the interfaces correctly?

  • Hardware recommendations for building an Ubuntu encrypted file server

    - by Robert Mashlan
    I would like to build a file server for my home network using Ubuntu. It will serve files from RAID1 configured disks, either in the OS or in hardware. It will be connected to a Gigabit ethernet LAN. The disks will use an encrypted file system. It will serve samba shares. I would like a recommendation on what kind of processing power/memory I would need to build a box that would be able to sustain the full capacity of the Gigabit ethernet connection in a file transfer for a single connection with the overhead of serving from an encrypted disk. I'm not looking to build a dream server, I just want enough processing capacity for high performance (and reliable) file sharing and spend as little as possible for it. This may be tangential, but what kind of hardware would I need to have a server be able to reliably go into a low power mode when no requests are being made of it?

  • How to set start screen tiles' language in Windows 8

    - by Robert Koritnik
    I've installed English Windows 8 x64 on my notebook and selected Slovenian as locale during installation. The problem I'm having now is that my tiles on start screen display in Slovenian even though my installation is English. I've also edited languages, adding English (British) on the list and putting it on top of Slovenian, but tiles still use Slovenian... All previous Windows versions were able to have English UI with a particular locale for input, time, dates, currency etc. How can I do the same in Windows 8?

  • Wallpaper in Windows 7 locked down by domain group policy?

    - by Robert Dailey
    So I am in a situation where my wallpaper is locked to a specific image on my work computer via group policy. I can't change it via the Personalization settings since it is grayed out and says it has been set by the system administrator. Anyone know some local GPO and/or registry hackery I can do to override the domain's policy? I could probably get away with logging in under a local account for this, but I want that to be a last resort. Thanks in advance.

    I have Thunderbird set up to auto-bcc my account for all emails, and disabled the 'Sent' folder. Unfortunately if I'm in an email threads and Reply to all I get double-copied: once by Reply to all; once bt auto-bcc. Are there any workarounds for this?

  • Is there an application that will move an active window to the system tray without minimizing it

    - by Robert
    I have an active application (lets say an instant messaging client) whose buddy list I have up (active) on one side of my screen at all times in Windows 7. I would like to remove that icon from the taskbar either by moving it to the system tray (as happens when the app is minimized) or by just removing it altogether. To be clear: I do not want to minimize the window to the system tray (as described in Windows app to hide application from taskbar) I want to keep the window its NORMAL size and location and just get rid of the taskbar icon for the app. I'm looking for any tool, third party, native, registry hack, to accomplish this.

  • How to control routes added by RasDial

    - by Robert Dodier
    I am using the RasDial function on a Windows box (Windows Server 2008) to dial a device from which the server then reads data. It seems that some new routes are added to the network routing table when the dial-up connection is made. That interferes with other network interfaces on the server. In particular, RasDial adds a default route which routes traffic to the device, which makes the server unreachable until the connection is dropped. Is there a way to control which routes are added by RasDial? I have been studying Microsoft's document for RasDial and associated items (RASDIALPARAMS, RASDIALEXTENSIONS) without finding anything about routing. There is an option for "Use default gateway on remote network" when configuring a VPN, but I don't see how to apply that in this case. Thanks for any light you can shed on this problem.

  • Which Windows 8 tool should I use to "read", "upload", my Windows 7 latest backup DVD (is it possible?)

    - by Robert
    Which Windows 8 tool should I use to "read", "upload", my Windows 7 latest backup DVD (is it possible?). I've just installed W8 and haven't made any changes to my new ecosystem and, what happened was that, as I was managing my new drivers, some mess* occurred, I confess, and now what I have left is every single backup tool I made use of W7, like system images, restore dvds, backup up to date monthly and so on, and would like to keep in touch with W8. I'm one of those with problems managing the amd switchable gpu drivers. Now I want to stay with W8 (download version - didn't clean install) but with my old personal files. I don't care to programs updates. I got everything original on dvds, of my interest. Yesterday I tried refreshing W8 once but didn't work. Maybe trying again tonight. What would you guys do in my place, please? *the mess I am talking about is to have disabled my intel (the only driver left) gpu in device manager tool in W8. I got black screen on system boot. Cheers, C.C.

  • Sending formatted Lotus Notes rich text email from Excel VBA

    - by Lunatik
    I have little Lotus Script or Notes/Domino knowledge but I have a procedure, copied from somewhere a long time ago, that allows me to email through Notes from VBA. I normally only use this for internal notifications where the formatting hasn't really mattered. I now want to use this to send external emails to a client, and corporate types would rather the email complied with our style guide (a sans-serif typeface basically). I was about to tell them that the code only works with plain text, but then I noticed that the routine does reference some sort of CREATERICHTEXTITEM object. Does this mean I could apply some sort of formatting to the body text string after it has been passed to the mail routine? As well as upholding our precious brand values, this would be quite handy to me for highlighting certain passages in the email. I've had a dig about the 'net to see if this code could be adapted, but being unfamiliar with Notes' object model, and the fact that online Notes resources seem to mirror the application's own obtuseness, meant I didn't get very far. The code: Sub sendEmail(EmailSubject As String, EMailSendTo As String, EMailBody As String, MailServer as String) Dim objNotesSession As Object Dim objNotesMailFile As Object Dim objNotesDocument As Object Dim objNotesField As Object Dim sendmail As Boolean 'added for integration into reporting tool Dim dbString As String dbString = "mail\" & Application.UserName & ".nsf" On Error GoTo SendMailError 'Establish Connection to Notes Set objNotesSession = CreateObject("Notes.NotesSession") On Error Resume Next 'Establish Connection to Mail File Set objNotesMailFile = objNotesSession.GETDATABASE(MailServer, dbString) 'Open Mail objNotesMailFile.OPENMAIL On Error GoTo 0 'Create New Memo Set objNotesDocument = objNotesMailFile.createdocument Dim oWorkSpace As Object, oUIdoc As Object Set oWorkSpace = CreateObject("Notes.NotesUIWorkspace") Set oUIdoc = oWorkSpace.CurrentDocument 'Create 'Subject Field' Set objNotesField = objNotesDocument.APPENDITEMVALUE("Subject", EmailSubject) 'Create 'Send To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("SendTo", EMailSendTo) 'Create 'Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("CopyTo", EMailCCTo) 'Create 'Blind Copy To' Field Set objNotesField = objNotesDocument.APPENDITEMVALUE("BlindCopyTo", EMailBCCTo) 'Create 'Body' of memo Set objNotesField = objNotesDocument.CREATERICHTEXTITEM("Body") With objNotesField .APPENDTEXT emailBody .ADDNEWLINE 1 End With 'Send the e-mail Call objNotesDocument.Save(True, False, False) objNotesDocument.SaveMessageOnSend = True 'objNotesDocument.Save objNotesDocument.Send (0) 'Release storage Set objNotesSession = Nothing Set objNotesMailFile = Nothing Set objNotesDocument = Nothing Set objNotesField = Nothing 'Set return code sendmail = True Exit Sub SendMailError: Dim Msg Msg = "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & Chr(13) & Err.Description MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext sendmail = False End Sub

  • Adding new record to a VFP data table in VB.NET with ADO recordsets

    - by Gerry
    I am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks. Any guidance would be greatly appreciated. cnn1.Open("Driver={Microsoft Visual FoxPro Driver};" & _ "SourceType=DBC;" & _ "SourceDB=" & mDataPath & ";Exclusive=No") Dim RS As ADODB.RecordsetS = New ADODB.Recordset RS.Open("select * from gennote", cnn1, 1, 3, 1) RS.AddNew() 'Assign values to the first three fields RS.Fields("ignnoteid").Value = NextIDI RS.Fields("cnotetitle").Value = "'" & mail.Subject & "'" RS.Fields("cfilename").Value = "''" 'Looping through 254 characters at a time and add the data 'to Ado Field buffer For i As Integer = 1 To Len(memo) Step liChunkSize liStartAt = i liWorkString = Mid(mail.Body, liStartAt, liChunkSize) RS.Fields("mnote").AppendChunk(liWorkString) Next 'Update the recordset RS.Update() RS.Requery() RS.Close()

  • How do I format the contents of a DataGrid cell as a Date? as Currency?

    - by Ben McCormack
    I have a Silverlight DataGrid that's being populated with different types of data for each column. I'm trying to figure out how to format some of the contents of the DataGrid's cells, specifically for dates and formatting. I have a date column that's currently displaying like: 3/11/2010 12:00:00 AM. I would rather it display like 3/14/2010. I have a number column that's currently displaying like: 51.32. I'd rather it display as currency like $51.32. I'm not sure how I can go about doing this. I'd prefer to do it in XAML instead of C#, but both solutions are fine. For reference, here's my XAML so far: </data:DataGridTextColumn> <data:DataGridTextColumn Header="Payee" Binding="{Binding Payee}"/> <data:DataGridTextColumn Header="Category" Binding="{Binding Category}"/> <data:DataGridTextColumn Header="Memo" Binding="{Binding Memo}"/> <data:DataGridTextColumn Header="Inflow" Binding="{Binding Inflow}"/> <data:DataGridTextColumn Header="Outflow" Binding="{Binding Outflow}"/> </data:DataGrid.Columns>

  • Writing an auto-memoizer in Scheme. Help with macro and a wrapper.

    - by kunjaan
    I am facing a couple of problems while writing an auto-memoizer in Scheme. I have a working memoizer function, which creats a hash table and checks if the value is already computed. If it has been computed before then it returns the value else it calls the function. (define (memoizer fun) (let ((a-table (make-hash))) (?(n) (define false-if-fail (?() #f)) (let ((return-val (hash-ref a-table n false-if-fail))) (if return-val return-val (begin (hash-set! a-table n (fun n)) (hash-ref a-table n))))))) Now I want to create a memoize-wrapper function like this: (define (memoize-wrapper function) (set! function (memoizer function))) And hopefully create a macro called def-memo which defines the function with the memoize-wrapper. eg. the macro could expand to (memoizer (define function-name arguments body ...) or something like that. So that I should be able to do : (def-memo (factorial n) (cond ((= n 1) 1) (else (* n (factorial (- n 1)))))) which should create a memoized version of the factorial instead of the normal slow one. My problem is that the The memoize-wrapper is not working properly, it doesnt call the memoized function but the original function. I have no idea how to write a define inside of the macro. How do I make sure that I can get variable lenght arguments and variable length body? How do I then define the function and wrap it around with the memoizer? Thanks a lot.

  • Saving table yields "Record is too large" in Access

    - by C. Ross
    I have an access database that I gave to a user (shame on my head). They were having trouble with some data being too long, so I suggested changing several text fields to memo fields. I tried this in my copy and it worked perfectly, but when the user tries it they get a "Record is too large" messagebox on saving the modified table design. Obviously the same record is not too large in my database, why would it be in theirs?

  • Deleting file with SharePoint List web service fails

    - by Robert MacLean
    I am trying to delete a file from SharePoint using the list web service which is failing with the following error. Error Code: 0x81020030 Message: Invalid file name Detail: The file name you specified could not be used. It may be the name of an existing file or directory, or you may not have permission to access the file. The update XML I sent through is: <Batch OnError="Continue" PreCalc="TRUE" ListVersion="0" ViewName="{8FE4E2C8-939E-4462-ABA2-D633EED7F76E}"><Method ID="1" Cmd="Delete"><Field Name="ID">84</Field><Field Name="FileRef">http://win-4h0xp59sn75:40414/Shared%20Documents/del.txt</Field></Method></Batch> The SharePoint server error logs indicate: ERROR: Failed to OpenThreadToken, LastError=1008 The file you are attempting to save or retrieve has been blocked from this Web site by the server administrators. Things I have tried I've tried the changes in #1372971 which has no helped. I have also tried the changes recommended on the Microsoft Social site, which has also not helped. I have confirmed that the txt file extension is not blocked as indicated here. In addition I can remove the file via the website, it is just on the web service that this fails. The permissions are correct (or rather not in play) as I am running as a SharePoint administrator, which is the same account that uploaded it via the copy web service.

  • Entity Framework - adding new items via a navigation property

    - by Robert
    I have come across what appears to be very peculiar behaviour using entity framework 4.0. I have a User entity, which has a Company (A Company has many Users). If I do this, everything works as expected and I get a nice shiny new user in the database: var company = _model.Companies.First(); company.Users.Add(new User(1, "John", "Smith")); _model.SaveChanges(); However, if I do this, then I get nothing new in the database, and no exceptions thrown: var existingUser = _model.Users.First(); var company = existingUser.Company; company.Users.Add(new User(1, "John", "Smith")); _model.SaveChanges(); So it appears that if I add a User to the Company that is pulled directly from the model, then everything works fine. However if the User is added to a Company that is pulled as a navigation property of another object, then it doesn't work. Can someone tell me if this is expected behaviour, or if there is something I can do to make it so that it is? Thanks!

  • .NET Access automation with Access 2007 Runtime

    - by Robert Morgan
    I'm having trouble deploying .NET application which uses Microsoft Access automation. I've installed the Access 2007 Runtime and Primary Interop Assemblies (PIAs) on the target machine: Access 2007 Runtime Office 2007 PIAs However, when I try to create the ApplicationClass: Application access = new ApplicationClass(); I get the following exception: Unhandled Exception: System.Runtime.InteropServices.COMException (0x80080005): Retrieving the COM class factory for component with CLSID {73A4C9C1-D68D-11D0-98BF-00A0C90DC8D9} failed due to the following error: 80080005. I've googled the error code and tried tweaking the security settings in dcomcnfg, to no avail. Any ideas? I don't want to install the full version of Access due to the cost, and the runtime should at least be able to create an instance of the application, surely?

  • Are Visual Studio Setup Projects suitable for complex setups

    - by Robert
    Are "Visual Studio Setup" Projects suitable for complex setups in different versions? The application is rather large ( 500.000 lines of code) and is under continuous development. Every 6 to 10 month a new version gets released. We have multiple configuration files (INI and XML), registry keys, database migration scripts, etc. The application is in the progress of being migrated from VB6 to .NET . The old installer was build with Installshield. The feedback to Installshield is: Bad adaptability, bad reuse - thats way we are evaluating "Visual Studio Setup" as an alternative. Other products we consider: Free Solutions WiX NSIS Commercial Solutions Installshield (again..) Wise Advanced Installer sth. missing? Solutions we don't like to consider: Inno Setup (It just doesn't feel right)
