  • Override properties block when including a psake script in an other psake script

    - by DanceAlot
    I am new to psake and I have this issue: I have 2 psake scripts: (1): base_tasks.ps1: properties{ $a = "hello" $b = "hi" } task One{ Write-Host $a } (2): install.ps1 Include .\base_tasks.ps1 properties{ $a = "Goodbye" $b = "Adjeu" } task default -depends One Now, is it possible to override the properties and variables from file 1? I want to use file 1 as "base tasks" and use the tasks in the install.ps1 and override the properties. Or do I have to do that an other way? I will invoke install.ps1 and use my $a and $b from install.ps1. DanceAlot

  • How to enabled Printer Sharing on Web Server 2008?

    - by FarrEver
    I am installing Web Server 2008 for my home network. I have 2 USB printers that I am connecting to this machine and want to share these printers so that my other machines can print to these 2 USB printers. (I previously had Win Server 2003 on this machine and was able to share both printers fine.) File and Printer sharing Inbound Role for my Private network is enabled, when I go into Network and Sharing Center and try to turn ON Printer Sharing, it never sticks. It always stays on OFF. I go to my installed printers and try to Share them and get the following error message: Printer Settings could not be saved. Remote connections to the Print Spooler are blocked by a policy set on your machine. I have not been able to find a policy on my machine that is preventing this. I have searched a lot over the past few days and most of the results say what I have done should work and there are also a number of search results that say Printer Sharing on Web Server 2008 is not allowed and you have to hack it. Has anyone installed Web Server 2008 and shared printers before? If so, what are the detailed steps you took to get this to work?

  • Printing special / extended characters on web page - Firefox or printer issue?

    - by edmicman
    My dad brought this to my attention and I'm looking into it, but thought I'd post here and see if anyone has any ideas... He's running Win7, using Firefox and printing to a wireless connected Brother HL-2170W printer. He's got a web page (http://cornandsoybeandigest.com/inputs/fertilizer/applying-nitrogen-after-planting-0512/index.html) that has extended/special characters in it - the funny "a" in Fernandez. The characters show correctly in Firefox on the page. He printed it, and the extended "a" printed as a diamond with a question mark. He says it shows that way in the print preview, too. I pulled up the same page in Ubuntu, Firefox, and it displayed in my print preview and physically printed everything correctly. I just checked on my wife's Win7 PC in Firefox and the print preview looked correct on her system, too. We have a Brother 2040 here. Soooo, my question is, is this possibly a problem in the browser somehow, or the printer driver? I'm leaning towards the printer driver now, but I can't say I've run into this before. Is it a setting somewhere? I just installed this printer for him the other day, using the CD that came with it; I could try updating the driver from Brother's website I guess. Is there anything else I should look at or check? Thanks!

  • Printing fails after first print with Centos 6 and HP LaserJet P3015dn printer

    - by Gavin Simpson
    Centos 6 recognises and configures a HP LaserJet P3015dn printer connected via USB. This machine is being configured as a small group file/print server. I can print a test page, which is processed/printed correctly. The next time printing is attempted (say printing a second test page), the page is not printed and the printer is set to disabled. The status of the printer is stated as: Stopped - /usr/lib/cups/backend/hp failed in the printer configuration dialogue. /var/log/cups/error_log contains this information (first two lines were there prior to the failed print job) E [24/Jun/2004:09:12:57 +0100] Returning HTTP Forbidden for Resume-Printer (ipp://localhost/printers/HP-LaserJet-P3010-Series) from localhost E [24/Jun/2004:09:20:59 +0100] Returning HTTP Forbidden for CUPS-Delete-Printer (ipp://localhost/printers/HP-LaserJet-P3010-Series) from localhost D [24/Jun/2004:09:37:28 +0100] [Job 28] The following messages were recorded from 09:36:43 AM to 09:37:28 AM D [24/Jun/2004:09:37:28 +0100] [Job 28] Adding start banner page "none".

  • Printer Redirection from 2003 Terminal Server to 2008 Terminal Server

    - by xmaveric
    Our environment is a terminal server cluster (Win2003 servers) that everyone connects to do do their work. I have set up a new Win2008 R2 machine with the intention of using it to publish our main application to the TS farm. The idea was to keep this server dedicated to one application to avoid driver/dll conflicts with other software. I created a RemoteApp on the new server and made an .rdp file and placed it on the desktop of our TS farm servers. The problem I am running into is that when I connect to the RemoteApp, it doesn't show the printers that are installed on the TS server I am connecting from. We have over 20 printers installed on our TS servers, each with different drivers and permissions. I really do not want to reinstall all of these on the RemoteApp server so I was hoping Printer Redirection would handle this. It would appear that because the RDP client for Server 2003 x64 is 6.0, that version doesn't support the Easy Print feature (requires 6.1). I can't find any newer version on the MS site to download for Win2003 x64. How can I get the printers on the TS farm machine to redirect so they are viewed by the RemoteApp machine?

  • Windows 7 add printer, cancelled, but port still in use. How to remove?

    - by Jake
    I tried to add a network printer at www.xxx.yyy.zzz, but halfway it when it asked for a driver, I cancelled it because I do not have the driver at hand. Later when I try to add again, it tells me the port (www.xxx.yyy.zzz), which is automatically specified as the same as the IP for the printer, is already in use and then suggest www.xxx.yyy.zzz_1 Now, I cannot find the www.xxx.yyy.zzz printer anywhere such that I can remove it and use back the same port. How should I do it? Any ideas? Thanks.

  • Does laser printer use toner when switched on/off?

    - by Alan Harris-Reid
    I have recently purchased a HP LaserJet M175nw laser printer which goes into sleep-mode after 10 minutes of non-use. I know sleep-mode uses a very small amount of power, but the flashing light on the control panel is driving me nuts! I know I can turn-off the printer via. the on/off button, but when it is turned-on manually, there is some whirring sound which I guess might be the machine warming-up. My question is... Is any toner used during this warm-up (or cleaning) cycle? Am I better-off keeping the printer in sleep mode, or is it ok to turn off manually? TIA Alan

  • Do any of the HP printers have implement printer sharing?

    - by BCS
    I've seen several (home grade) HP prints that have network port and allow connecting to them via that. However I haven't seen any way to use it without installing the printer specific drives. This seems a bit silly because I've seen printer sharing system (SMB I think) that didn't seem to need any printer specific software. My question is: Is there a way to use one of these with my printers? (I'm omitting the exact model in the hopes that answers for several models (or a resource that answers it for several models) will be given.)

  • How to make Delphi Prism indexed properties visible to C# when properties are not default

    - by Arcturus
    I have several Delphi Prism classes with indexed properties that I use a lot on my C# web applications (we are migrating a big Delphi Win32 system to ASP.Net). My problem is that it seems that C# can't see the indexed properties if they aren't the default properties of their classes. Maybe I'm doing something wrong, but I'm completely lost. I know that this question looks a lot like a bug report, but I need to know if someone else knows how to solve this before I report a bug. If I have a class like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; default; // make IndexedBool the default property end; I can use this class in C# like this: var myObj = new TMyClass(); myObj[0] = true; However, if TMyClass is defined like this: TMyClass = public class private ... method get_IndexedBool(index: Integer): boolean; method set_IndexedBool(index: Integer; value: boolean); public property IndexedBool[index: Integer]: boolean read get_IndexedBool write set_IndexedBool; // IndexedBool is not the default property anymore end; Then the IndexedBool property becomes invisible in C#. The only way I can use it is doing this: var myObj = new TMyClass(); myObj.set_IndexedBool(0, true); I don't know if I'm missing something, but I can't see the IndexedBool property if I remove the default in the property declaration. Besides that, I'm pretty sure that it is wrong to have direct access to a private method of a class instance. Any ideas?

  • Mouse settings/properties dialog box won't open in Windows 7

    - by ymasood
    Hi, I have a problem trying to open my computer's mouse settings by either going to the command prompt and typing, 'control mouse', 'main.cpl' (as researched online) or simply by trying to go to the Control Panel and clicking on 'Mouse' under Hardware and Sound section. I have also tried running cmd as Administrator and trying the above commands but that is of no help. Lastly, if I search for 'mouse' and click 'Mouse' from the Windows search bar, that doesn't work either. In the past I had bought and installed Microsoft Wireless Mobile Mouse 6000 software and have just now bought and installed HP's Wireless Comfort Mobile mouse. Any help in this regard is highly recommended. I won't be able to restore or reinstall my laptop since it's a heavy use machine. Thanks! Yasser

  • Very slow printing from print server

    - by evolvd
    Print server is a VM on Xen The VM is Windows 2003 32bit. During the issue the VM is not being taxed in anyway, cpu, memory, hd read/write, and network speed is all good. The problem that I see is the transfer of the print file from the print server to the printer. The 80Mb file is transferred from the client to the print server in about 2 minutes but then it takes about 2 hours for that file to be sent to the printer. I can't figure out why this would just start to happen. The printer is rebooted every evening and is just used for one large print job in the morning. The server has been rebooted with no effect I changed the spool option to send the entire spool to the server before printing starts and it had no effect. This printer problem did happen to come about after some changes to the Xen environment. The Xen servers changed from using HBA NIC cards to software iscsi and a new switch was put in. I don't think this is related to the problem since all the speeds on the VMs are better now. The changed happened on Saturday and the first print to this printer happened on Monday morning. I'm just putting that out there but like I said I don't think it is related but I don't want to rule it out. At this point I don't have many other options besides the physical layer. I can switch out network cable that goes to the printer and I might be able to print the same job to another printer. I wont be able to test those things out till this afternoon though. Any other ideas or test I could do to try to find the reason for the slow speed? I forgot to say that this is only happening when printing to this one printer. ===Update=== I found out that there are a few printers that currently have this issue, not just the one. There are over 30 printers on the server though so I know it's not happening to all of them. I printed a large pdf doc from the server and it was able to print at the normal speed. If the machine sends the large print request it gets to the server fine but then slow to get from the server to the printer. If sent directly from the printer it gets to the printer at the normal speed. The question now is why is there a speed difference when it comes from the machine and why would it start now?

  • Diagnosing the problem when Canon printer fails to print under Ubuntu

    - by MMA
    I understand that the issue of Canon printer under Linux has a number of posts. Actually one of these, was started by me. After inputs from others I have successfully printed using Canon LBP6000 from my Ubuntu machine for around a year. If it failed to print, restarting the daemon using this homemade script coaxed the printer to print. #!/bin/bash pkill -9 -x ccpd pkill -9 -x captmoncnabc /etc/init.d/ccpd start /etc/init.d/ccpd status Recently, I am not successful any more, or successful on a limited and sporadic basis. Sometimes it prints when turned on after logging in, sometimes when the driver is reinstalled. I keep on trying the random steps (call abracadabras) until I get success. Again, not always success comes. I frustrate on for hours only to get single page printed. I loose precious time on the issue of printing. I have read and read all the documents available over the Internet. However, if you please notice, none of the guides, articles, tutorials (these are too many to list here) seem to be dealing with diagnosing the problem when it fails to print. They tell you where to find the drivers, how to install them, or which script to run to make the installation process automatic. Yes, some of the articles or comments suggest a step to try, without any systematic order. But these fail to suggest a step based on symptoms, mostly. This morning, my Canon LBP6000 failed to print. After sometime, there was a message for system error, details of which was found to be something like this. When I search for this error (c3pldrv crashed with SIGSEGV in write ()), I find a number of articles including this one. None of these are actually helpful. Mostly, these are 'me too', 'tell me if you find anything'. Running captstatusui -P LBP6000 produced this, Yes, the printer is connected and actually turned on. I believe that there a number of frustrated Canon printer users out there like me. But there is not a step by step definitive guide to systematically diagnose a non-printing printer. Do you think that you can provide your diagnosing inputs so that a systematic document can be built? May be we will want the Ubuntu users to stay away from Canon printers. But as I believe, as a Linux user for more than fifteen years, such a scenario is not acceptable any more. May be this was acceptable in the infancy days of Linux, but not today. I am using Ubuntu 12.04, by the way, I prefer LTS versions.

  • Use of properties vs backing-field inside owner class

    - by whatispunk
    I love auto-implemented properties in C# but lately there's been this elephant standing in my cubicle and I don't know what to do with him. If I use auto-implemented properties (hereafter "aip") then I no longer have a private backing field to use internally. This is fine because the aip has no side-effects. But what if later on I need to add some extra processing in the get or set? Now I need to create a backing-field so I can expand my getters and setters. This is fine for external code using the class, because they won't notice the difference. But now all of the internal references to the aip are going to invoke these side-effects when they access the property. Now all internal access to the once aip must be refactored to use the backing-field. So my question is, what do most of you do? Do you use auto-implemented properties or do you prefer to always use a backing-field? What do you think about properties with side-effects?

  • How can I invoke the dialog to set printer options manually?

    - by FromTheMountain
    I'm using WPF and need to let users set some print related options like printer and printer properties (e.g. papertray, landscape/portrait, duplex, etc). I'm aware of the PrintDialog class to get a PrintQueue and PrintTicket object. However I need to create I custom solution and can not show the PrintDialog. I manage to get the available PrintQueue objects and let users select a printer. I'm struggling with the printer properties. My question is: how can I show the dialog in which a user can set the printer properties for the selected PrintQueue (the dialog that is shown when a user clicks on the Properties button in the WPF PrintDialog).

  • Delayed "rendering" of WPF/Silverlight Dependency Properties?

    - by Aardvark
    Is there a way to know the first time a Dependency Property is accessed through XAML binding so I can actually "render" the value of the property when needed? I have an object (class derived from Control) that has several PointCollection Dependency Properties that may contain 100's or 1000's of points. Each property may arrange the points differently for use in different types shapes (Polyline, Polygon, etc - its more complicated then this, but you get the idea). Via a Template different XAML objects use TemplateBinding to access these properties. Since my object uses a Template I never know what XAML shapes may be in use for my object - so I never know what Properties they may or may not bind to. I'd like to only fill-in these PointCollections when they are actually needed. Normally in .NET I'd but some logic in the Property's getter, but these are bypassed by XAML data binding. I need a WPF AND Silverlight compatible solution. I'd love a solution that avoids any additional complexities for the users of my object.

  • Add properties to stdClass object from another object

    - by Florin
    I would like to be able to do the following: $obj = new stdClass; $obj->status = "success"; $obj2 = new stdClass; $obj2->message = "OK"; How can I extend $obj so that it contains the properties of $obj2, eg: $obj->status //"success" $obj->message // "OK" I know I could use an array, add all properties to the array and then cast that back to object, but is there a more elegant way, something like this: extend($obj, $obj2); //adds all properties from $obj2 to $obj Thanks!

  • How to have Vista OS send documents to printer without waiting in front?

    - by Greenleader
    Hi, I got a print server on our old printer. I have a problem, because Vista has its own queue. I want to bypass this queue and send everything straight away to printer so the print server deals with queue and not vista. Problem is, when second document is being printed from the same computer after first one. Vista is still waiting for info on finishing the first job even 5 minutes after it was REALLY finished.
