  • Terminal services and screen savers

    - by Corsair
    I have a Window Server 2008 R2 server acting as a terminal server for mobile devices running a single application, but I am having issues with the screen saver popping on after ten minutes. Is there a setting in terminal services to make the screensaver settings universal? If not, how should I approach this issue?

  • Install a program from the network

    - by Gomibushi
    In Windows there is a place under the Control Panel called Get Programs and Install a program from the network (in Win 7 at least), possibly a slightly different name in Vista, but it was there too. The question is basically: How do you publish programs to that so users can go there and install? Bonus follow up: Is it a good way to deploy optional programs? (Compared to using GPO's.) In Windows 7 you can go to Control Panel, Programs, Programs and Features, and on the left hand menu: Install a program from the network.

  • Connection Filtering with Multiple DNSBL's?

    - by JohnyD
    Is there any advantage or disadvantage to using multiple DNSBL's with ones connection filtering? I just switched from SpamHaus to BarracudaCentral but have added in SpamHaus to test for increased effectiveness. So far there is no dip in performance and no increased load on our SMTP server.

  • Xpath > How can I select a node based on both its attributes and content?

    - by Andrew Kirk
    Sample XML: <assignments> <assignment id="911990211" section-id="1942268885" item-count="21" sources="foo"> <options> <value name="NumRetakes">4</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">-1</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignment id="1425185257" section-id="1505958877" item-count="4" sources="bar"> <options> <value name="NumRetakes">0</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">3</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignments> Using XPath, I would like to select all assignments/assignment/options/value nodes where the nodes "name" attribute is "MaxFeedbackAttempts" and the nodes content is "-1". That is to say, I want to return each node that looks like: <value name="MaxFeedbackAttempts">-1</value> I can get each assignments/assignment/options/value node with the specified attribute using: //assignment/options/value[@name="MaxFeedbackAttempts"] I am just not sure how to refine this path to also limit the results based on the nodes content. Is there any way to do this using XPath?

  • Pushin each_line into array not working

    - by zettt
    Hi, I've got a weird issue with Ruby. I want to read data from a file and put the data then into an array. The weird thing is, it's working in another script which does basically, the same thing. quoteArray = [] quoteFile = File.new("quotes.txt", "r") or die "Unable to open file..." quoteFile.each_line { |line| quoteArray.push line } puts quoteArray[0] All I get out of this is an array with one element where the whole text file is in. What's wrong? Is it my machine? The text file? Any ideas? Thanks in advance

  • Outsourcing Studies

    - by Mashmagar
    Outsourcing is typically disliked by programmers, but does anyone know any empirical studies of the cost/benefits of outsourcing for a company? I'm not looking for personal experiences here (as entertaining/frightening as they may be), but for actual research studies.

  • Visual Studio keeps inserting absurd default property value in designer file

    - by Bugz R us
    i have a simple usercontrol with following properties: public partial class RichTextEditorControl : UserControl { public string EditorText { get { return richTextBox1.Rtf; } set { richTextBox1.Rtf = value; } } public string EditorPlainText { get { return richTextBox1.Text; } set { richTextBox1.Text = value; } } } Now whenever I EDIT a form which contains this control, VS fills its designer file with the following code line, and then throws a designer error : this.richTextEditorControl1.EditorPlainText = global::Project.Resources.MyResources_de_DE.SomeString; Now I don't know where it gets this value from ??? I've searched entire solution, and nowhere there's mention of this var, except for 1 file, where it's needed ... Moreover, the code VS writes, has an error in it ?! It doesn't compile ... The only thing I can do is edit the designer file, but the next time I have to edit the form with the designer, the same error happens again ... Where on earth is VS getting this value from ??

  • Maven (EJB) project with client and server artifacts

    - by Cornel Masson
    Here's my variation on the "multiple artifacts from Maven build" question: I'm porting from Ant to Maven. My application is an EJB server that is packaged as an EAR, but it also exposes a client JAR for use by other client apps. This jar contains the EJB interfaces, facade class and some helpers. I know that the Maven way is to have one artifact per project (POM); however, both artifacts (server EAR and client JAR) need to be built from the same source tree - server and client share, for example, the EJB and 'home' interfaces. How do I do this in Maven? Do I have one project containing two POMs, say server-pom.xml & client-pom.xml? I was thinking I could also have a parent POM (pom.xml) that can be used to build both client and server with one foul swoop? However, the lifecycles diverge after the 'package' phase, since the server has to go through assembly (tar/gzip), while the client is done after 'package' and can simply be installed into the repository. Any advice/experience on the best way to approach this?

  • Win CE 6.0 client using WCF Services - Reduce Bandwidth

    - by Sean
    We have a Win CE 6.0 device that is required to consume services that will be provided using WCF. We are attempting to reduce bandwidth usage as much as possible and with a simple test we have found that using UDP instead of HTTP saved significant data usage. I understand there are limitations regarding WCF on .NET Compact Framework 3.5 devices and was curious what people thought would be the appropriate way forward. Would it make sense to develop a custom UDP binding, and would that work for both sides? Any feedback would be appreciated. Thanks.

  • How to tell Java SAX Parser to ignore invalid character references?

    - by Epaga
    When trying to parse incorrect XML with a character reference such as &#x1, Java's SAX Parser dies a horrible death with a fatal error such as org.xml.sax.SAXParseException: Character reference "&#x1" is an invalid XML character. Is there any way around this? Will I have to clean up the XML file before I hand it off to the SAX Parser? If so, is there an elegant way of going about this?

  • Creating a cocoa Application without nib files/fully pragmatic

    - by Moddy
    Yes, I know this goes against the whole MVC principle! However, I'm just trying to whip up a pretty trivial application - and I've pretty much implemented it pragmatically. However, I have a problem... I create an Empty Project, copy all the frameworks over and set the build settings - and I get errors about the executable.. or lack of executable. The build settings all appear fine, but it tells me there is no executable - it will build + run fine.. however it doesn't run. There is no error either - it just appears to run very fast and cleanly! Unless I try and run gdb which politely tells me I need to give it a file first.. Running… No executable file specified. Use the "file" or "exec-file" command. So I created a Cocoa Application, removed all the stuff I didn't need (i.e the MainMenu.xib file..) and now I can compile my code perfectly.. however it dies with complaining that its "Unable to load nib file: MainMenu, exiting" I have gone through the Project Symbols and see that the code actually relies upon the nib file heavily, even if you don't touch it code-wise. (MVC again I guess..) So my question is - is there a simple way to compile just what you code, no added nib files, just the code you write and the frameworks you add? I assume it would be a blank project but my experience tells me otherwise?!

    - by henna
    In my application i have a button initially on the screen and in onclick of the button ,popup window should open. In the popup window i have an imagebutton , now on click of this button i want to start an activity. The popup window opens but i dont understand how to handle the onclick of the imagebtn inside popup window. In main.xml i have a button and in popup_example.xml i have an imagebutton. Hi my Java code is as follows: final LayoutInflater inflater = (LayoutInflater)this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); final Button b=(Button)findViewById(R.id.btn); b.setOnClickListener(new OnClickListener() { public void onClick(View v) { PopupWindow pw = new PopupWindow(inflater.inflate(R.layout.popup_example,(ViewGroup)findViewById(R.layout.main))); pw.showAtLocation(v, Gravity.LEFT,0,0); pw.update(8,-70,150,270); //if onclick written here, it gives null pointer exception. ImageButton img=(ImageButton)findViewById(R.id.home); img.setOnClickListener(new OnClickListener() { public void onClick(View v) { Intent..... } }); //if onclick is written here it gives runtime exception. }); and i have two xml layouts.........1)main.xml 2)popup_example.xml main.xml popup_example.xml <ImageButton android:id="@+id/home" android:layout_width="wrap_content" android:layout_height="wrap_content" android:focusable="true" android:src="@drawable/vitalss" android:layout_weight="1" android:background="#8E2323" />

  • ASP.NET HttpContext.GetLocalResourceObject() throws InvalidOperationException

    - by Dylan Lin
    Hi all, Let's say we have such site structure: App_LocalResources       |- A.aspx.resx       |- B.aspx.resx A.aspx B.aspx Now I use HttpContext.GetLocalResourceObject("~/A.aspx") in A.aspx.cs, and it works fine. But if I use HttpContext.GetLocalResourceObject("~/A.aspx") in B.aspx.cs, it throws an exception: The resource class for this page was not found. Please check if the resource file exists and try again. Exception Details: System.InvalidOperationException: The resource class for this page was not found. Please check if the resource file exists and try again. How can I resolve this problem? I want to read the local resources from an external page, and I don't want to read the .resx file myself. Thanks :-)

  • Problem with upper-case and lower-case xpath functions in selenium IDE

    - by Aristotelis
    Hi, I am trying to get a xpath query using the xpath function lower-case or uppper-case, but they seem to not work in selenium (where I test my xpath before I apply it). Example that does NOT work: //*[.=upper-case('some text')] I have no problem locating the nodes I need in complex path and even using aggregated functions, as long as I don't use the upper and lower case. Has anyone encountered this before? Does it make sense? Thanks.

  • Can we have a component-scoped bean in a JSF2 composite component?

    - by Pradyumna
    Hi, I was wondering how I could create "component-scoped" beans, or so-to-say, "local variables inside a composite component" that are private to the instance of the composite component, and live as long as that instance lives. Below are more details, explained with an example: Suppose there is a "calculator" component - something that allows users to type in a mathematical expression, and evaluates its value. Optionally, it also plots the associated function. I can make a composite component that has: a text box for accepting the math expression two buttons called "Evaluate", and "Plot" another nested component that plots the function It is evidently a self-contained piece of function; so that somebody who wants to use it may just say <math:expressionEvaluator /> But obviously, the implementation would need a java object - something that evaluates the expression, something that computes the plot points, etc. - and I imagine it can be a bean - scoped just for this instance of this component, not a view-scoped or request-scoped bean that is shared across all instances of the component. How do I create such a bean? Is that even possible with composite components?

  • Overflow exception while performing parallel factorization using the .NET Task Parallel Library (TPL

    - by Aviad P.
    Hello, I'm trying to write a not so smart factorization program and trying to do it in parallel using TPL. However, after about 15 minutes of running on a core 2 duo machine, I am getting an aggregate exception with an overflow exception inside it. All the entries in the stack trace are part of the .NET framework, the overflow does not come from my code. Any help would be appreciated in figuring out why this happens.

  • Counting a cell up per Objects

    - by Auro
    hey i got a problem once again :D a little info first: im trying to copy data from one table to an other table(structure is the same). now one cell needs to be incremented, beginns per group at 1 (just like a histroy). i have this table: create table My_Test/My_Test2 ( my_Id Number(8,0), my_Num Number(6,0), my_Data Varchar2(100)); (my_Id, my_Num is a nested PK) if i want to insert a new row, i need to check if the value in my_id already exists. if this is true then i need to use the next my_Num for this Id. i have this in my Table: My_Id My_Num My_Data 1 1 'test1' 1 2 'test2' 2 1 'test3' if i add now a row for my_Id 1, the row would look like this: i have this in my Table: My_Id My_Num My_Data 1 3 'test4' this sounds pretty easy ,now i need to make it in a SQL and on SQL Server i had the same problem and i used this: Insert Into My_Test (My_Id,My_Num,My_Data) SELECT my_Id, ( SELECT CASE ( CASE MAX(a.my_Num) WHEN NULL THEN 0 Else Max(A.My_Num) END) + b.My_Num WHEN NULL THEN 1 ELSE ( CASE MAX(a.My_Num) WHEN NULL THEN 0 Else Max(A.My_Num) END) + b.My_Num END From My_Test A where my_id = 1 ) ,My_Data From My_Test2 B where my_id = 1; this Select gives null back if no Rows are found in the subselect is there a way so i could use max in the case? and if it give null back it should use 0 or 1? greets Auro
