  • Problem getting weeks in a month...

    - by AngrySpade
    I am creating a calendar control of sorts... One thing I need to know is how many weeks are there in a Month... So NSCalendar rangeOfUnit:inUnit:forDate Seems to be exactly what I need... Except I am noticing something that seems off and I can't quite figure out why this is happening... The following code... NSCalendar *calendar = [NSCalendar currentCalendar]; NSDateComponents *dateComponents = [[NSDateComponents alloc] init]; [dateComponents setYear: 2010]; [dateComponents setDay: 1]; for (int x=1; x<=12; x++) { [dateComponents setMonth: x]; NSDate *date = [calendar dateFromComponents:dateComponents]; NSLog(@"Date: %@", date); NSRange range = [calendar rangeOfUnit: NSWeekCalendarUnit inUnit: NSMonthCalendarUnit forDate:date]; NSLog(@"%d Weeks in Month %d", range.length, [dateComponents month]); } Is returning the following debug messages... 2010-03-14 13:08:10.350 Scrap[4256:207] Date: 2010-01-01 00:00:00 -0500 2010-03-14 13:08:10.351 Scrap[4256:207] 5 Weeks in Month 1 2010-03-14 13:08:10.352 Scrap[4256:207] Date: 2010-02-01 00:00:00 -0500 2010-03-14 13:08:10.352 Scrap[4256:207] 4 Weeks in Month 2 2010-03-14 13:08:10.353 Scrap[4256:207] Date: 2010-03-01 00:00:00 -0500 2010-03-14 13:08:10.353 Scrap[4256:207] 5 Weeks in Month 3 2010-03-14 13:08:10.354 Scrap[4256:207] Date: 2010-04-01 00:00:00 -0400 2010-03-14 13:08:10.355 Scrap[4256:207] 5 Weeks in Month 4 2010-03-14 13:08:10.356 Scrap[4256:207] Date: 2010-05-01 00:00:00 -0400 2010-03-14 13:08:10.357 Scrap[4256:207] 5 Weeks in Month 5 2010-03-14 13:08:10.358 Scrap[4256:207] Date: 2010-06-01 00:00:00 -0400 2010-03-14 13:08:10.358 Scrap[4256:207] 5 Weeks in Month 6 2010-03-14 13:08:10.359 Scrap[4256:207] Date: 2010-07-01 00:00:00 -0400 2010-03-14 13:08:10.360 Scrap[4256:207] 5 Weeks in Month 7 2010-03-14 13:08:10.361 Scrap[4256:207] Date: 2010-08-01 00:00:00 -0400 2010-03-14 13:08:10.364 Scrap[4256:207] 5 Weeks in Month 8 2010-03-14 13:08:10.364 Scrap[4256:207] Date: 2010-09-01 00:00:00 -0400 2010-03-14 13:08:10.365 Scrap[4256:207] 5 Weeks in Month 9 2010-03-14 13:08:10.366 Scrap[4256:207] Date: 2010-10-01 00:00:00 -0400 2010-03-14 13:08:10.366 Scrap[4256:207] 5 Weeks in Month 10 2010-03-14 13:08:10.367 Scrap[4256:207] Date: 2010-11-01 00:00:00 -0400 2010-03-14 13:08:10.367 Scrap[4256:207] 5 Weeks in Month 11 2010-03-14 13:08:10.369 Scrap[4256:207] Date: 2010-12-01 00:00:00 -0500 2010-03-14 13:08:10.369 Scrap[4256:207] 52 Weeks in Month 12 I cant quite figure out why I get 52 weeks in month 12. Any clues? Edit on 3/20/2010: Seeing as how I couldnt use rangeOfUnit:inUnit:forDate to calculate the number of weeks in a month. I decided to figure out a different way of calculating the same value. I figured I should do this in a non-Gregorian localized way, so I attempted to start with getting the number of days in a week, but I got the result of 28 days in a week. So I started writing more code to figure out why... I wanted to make sure that the type of NSCalendar that I was playing with was in fact what I was supposed to be getting... And that led me to finding some differences... NSCalendar *currentCalendar = [NSCalendar currentCalendar]; NSLog(@"Calendar with 'currentCalendar' Identifier: %@", [currentCalendar calendarIdentifier]); NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; NSLog(@"Calendar created with identifier Identifier: %@", [calendarWithIdentifier calendarIdentifier]); NSDate *now = [[NSDate alloc] init]; NSDateComponents *currentMonth = [currentCalendar components: NSMonthCalendarUnit | NSYearCalendarUnit fromDate: now]; NSDate *currentMonthDate = [currentCalendar dateFromComponents: currentMonth]; NSRange daysInWeekRange = [currentCalendar rangeOfUnit: NSDayCalendarUnit inUnit: NSWeekCalendarUnit forDate: currentMonthDate]; NSLog(@"CurrentCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location); currentMonth = [calendarWithIdentifier components: NSMonthCalendarUnit | NSYearCalendarUnit fromDate: now]; currentMonthDate = [calendarWithIdentifier dateFromComponents: currentMonth]; daysInWeekRange = [calendarWithIdentifier rangeOfUnit: NSDayCalendarUnit inUnit: NSWeekCalendarUnit forDate: currentMonthDate]; NSLog(@"GregorianCalendar: Length:%u Location:%u", daysInWeekRange.length, daysInWeekRange.location); And that got me the following log results... 2010-03-20 21:02:27.245 Scrap[52189:207] Calendar with 'currentCalendar' Identifier: gregorian 2010-03-20 21:02:27.246 Scrap[52189:207] Calendar created with identifier Identifier: gregorian 2010-03-20 21:02:27.248 Scrap[52189:207] CurrentCalendar: Length:28 Location:1 2010-03-20 21:02:27.249 Scrap[52189:207] GregorianCalendar: Length:7 Location:1 Taking direction from @CarlNorum's experience, I compiled the code snippet as a 10.6 Cocoa application, and I got the following... 2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar with 'currentCalendar' Identifier: gregorian 2010-03-20 21:05:35.636 ScrapCocoa[52238:a0f] Calendar created with identifier Identifier: gregorian 2010-03-20 21:05:35.637 ScrapCocoa[52238:a0f] CurrentCalendar: Length:6 Location:1 2010-03-20 21:05:35.638 ScrapCocoa[52238:a0f] GregorianCalendar: Length:7 Location:1 I saw hope in that creating a NSCalendar Instance explicitly as a Gregorian Calendar would lead to better results in my original problem... So I modified that original code NSCalendar *currentCalendar = [NSCalendar currentCalendar]; NSLog(@"Calendar with 'currentCalendar' Identifier: %@", [currentCalendar calendarIdentifier]); NSCalendar *calendarWithIdentifier = [[[NSCalendar alloc] initWithCalendarIdentifier: NSGregorianCalendar] autorelease]; NSLog(@"Calendar created with identifier Identifier: %@", [calendarWithIdentifier calendarIdentifier]); NSDateComponents *dateComponents = [[[NSDateComponents alloc] init] autorelease]; [dateComponents setYear: 2010]; [dateComponents setDay: 1]; for (int x=1; x<=12; x++) { [dateComponents setMonth: x]; NSDate *date = [currentCalendar dateFromComponents: dateComponents]; NSRange range = [currentCalendar rangeOfUnit: NSWeekCalendarUnit inUnit: NSMonthCalendarUnit forDate: date];

  • Need help troubleshooting why Solr wont start (or why solr admin page wont show)

    - by Camran
    I can't get Solr working. I have Jetty, and my server OS is Ubuntu 9.10. It is a VPS server. So, when I execute the java -jar start.jar everything seems fine. I even do a netstat to check if there are any listeners on the port before the start and after the start, and it seems solr is starting. However, I cant access the admin page. I have even turned off the firewall. Here is some info about my server: I have changed DocumentRoot to var/www/SV/ I have Apache2, PHP5, MySql installed I have "disabled" iptables firewall I have removed the htaccess files (I used them to passw protect my site under develop) I have installed JRE (NOT JDK) on my server. I use the "example" which comes with Solr, so I use Jetty as container on my Server. My Server has 768MB RAM Doing a java -version command shows this: java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode) And in the terminal the last lines when executing start.jar is: May 29, 2010 1:30:03 PM org.apache.solr.core.SolrCore registerSearcher INFO: [] Registered new searcher Searcher@1dc64a5 main NOTE: Also before this last line, there is a line which makes me suspicious: Started SocketConnector @ 0.0.0.0:8983 // Should this be with leading zeros? Is there any ways you know to troubleshoot this? Memory issue maybe? Thanks

  • XSL apply templates not working...could be XPath error

    - by AdRock
    I have converted mny stylesheet to use apply templates instead of call templates and it worked fine for my other styesheet, which was more complicated, but this one doesn't seem to work even thought it is a much simpler template. All that it outputs is the sex node and the userlevel node. I think it has to do with my Xpath. All i want is to output the < user information, nothing else <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template name="hoo" match="/"> <html> <head> <title>Registered Members</title> <link rel="stylesheet" type="text/css" href="user.css" /> </head> <body> <h1>Registered Members</h1> <xsl:for-each select="folktask/member/user"> <div class="userdiv"> <xsl:apply-templates/> </div> </xsl:for-each> </body> </html> </xsl:template> <xsl:template match="folktask/member/user"> <xsl:apply-templates select="@id"/> <xsl:apply-templates select="personal/name"/> <xsl:apply-templates select="personal/address1"/> <xsl:apply-templates select="personal/city"/> <xsl:apply-templates select="personal/county"/> <xsl:apply-templates select="personal/postcode"/> <xsl:apply-templates select="personal/telephone"/> <xsl:apply-templates select="personal/mobile"/> <xsl:apply-templates select="personal/email"/> <xsl:apply-templates select="personal"/> <xsl:apply-templates select="account/username"/> <xsl:apply-templates select="account"/> </xsl:template> <xsl:template match="@id"> <div class="heading bold"><h2>USER ID: <xsl:value-of select="." /></h2></div> </xsl:template> <xsl:template match="personal/name"> <div class="small bold">NAME:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/address1"> <div class="small bold">ADDRESS:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/city"> <div class="small bold">CITY:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/county"> <div class="small bold">COUNTY:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/postcode"> <div class="small bold">POSTCODE:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/telephone"> <div class="small bold">TELEPHONE:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="personal/mobile"> <div class="small bold">MOBILE:</div> <div class="large"><xsl:value-of select="." /> </div> </xsl:template> <xsl:template match="personal/email"> <div class="small bold">EMAIL:</div> <div class="large"> <xsl:element name="a"> <xsl:attribute name="href"> <xsl:text>mailto:</xsl:text> <xsl:value-of select="." /> </xsl:attribute> <xsl:value-of select="." /> </xsl:element> </div> </xsl:template> <xsl:template match="personal"> <div class="small bold">SEX:</div> <div class="colored bold"> <xsl:choose> <xsl:when test="sex='Male'"> <div class="sex male"><xsl:value-of select="sex/."/></div> </xsl:when> <xsl:otherwise> <div class="sex female"><xsl:value-of select="sex/."/></div> </xsl:otherwise> </xsl:choose> </div> </xsl:template> <xsl:template match="account/username"> <div class="small bold">USERNAME:</div> <div class="large"><xsl:value-of select="." /></div> </xsl:template> <xsl:template match="account"> <div class="small bold">ACCOUNT TYPE:</div> <div class="colored "> <xsl:choose> <xsl:when test="userlevel='1'"> <div class="nml bold">Normal User</div> </xsl:when> <xsl:when test="userlevel='2'"> <div class="vol bold">Volunteer</div> </xsl:when> <xsl:when test="userlevel='3'"> <div class="org bold">Organiser</div> </xsl:when> <xsl:otherwise> <div class="name adm bold">Administrator</div> </xsl:otherwise> </xsl:choose> </div> </xsl:template> </xsl:stylesheet> and some of my xml <?xml version="1.0" encoding="ISO-8859-1" ?> <?xml-stylesheet type="text/xsl" href="users.xsl"?> <folktask xmlns:xs="http://www.w3.org/2001/XMLSchema-instance" xs:noNamespaceSchemaLocation="folktask.xsd"> <member> <user id="1"> <personal> <name>Abbie Hunt</name> <sex>Female</sex> <address1>108 Access Road</address1> <address2></address2> <city>Wells</city> <county>Somerset</county> <postcode>BA5 8GH</postcode> <telephone>01528927616</telephone> <mobile>07085252492</mobile> <email>[email protected]</email> </personal> <account> <username>AdRock</username> <password>269eb625e2f0cf6fae9a29434c12a89f</password> <userlevel>4</userlevel> <signupdate>2010-03-26T09:23:50</signupdate> </account> </user> <volunteer id="1"> <roles></roles> <region>South West</region> </volunteer> </member> <member> <user id="2"> <personal> <name>Aidan Harris</name> <sex>Male</sex> <address1>103 Aiken Street</address1> <address2></address2> <city>Chichester</city> <county>Sussex</county> <postcode>PO19 4DS</postcode> <telephone>01905149894</telephone> <mobile>07784467941</mobile> <email>[email protected]</email> </personal> <account> <username>AmbientExpert</username> <password>8e64214160e9dd14ae2a6d9f700004a6</password> <userlevel>2</userlevel> <signupdate>2010-03-26T09:23:50</signupdate> </account> </user> <volunteer id="2"> <roles>Van Driver,gas Fitter</roles> <region>South Central</region> </volunteer> </member> </folktask>

  • DomainContext class is not created in a RIA services class library solution

    - by Konamiman
    I have created a RIA services class library project and things are not going as I expected. The problem is that when I add domain service classes to the server project, the corresponding domain context classes are not generated on the client project. I start by creating a new project of type WCF RIA services class library. The generated solution has two projects: RIAServicesLibrary1 (the Silverlight class library project) and RIAServicesLibrary1.Web (the class library that will hold the services). Then I add a new project item to RIAServicesLibrary1.Web of type DomainServiceClass. I add a sample method so that the resulting class code is: namespace RIAServicesLibrary1.Web { using System; using System.Collections.Generic; using System.ComponentModel; using System.ComponentModel.DataAnnotations; using System.Linq; using System.ServiceModel.DomainServices.Hosting; using System.ServiceModel.DomainServices.Server; // TODO: Create methods containing your application logic. [EnableClientAccess()] public class DomainService1 : DomainService { [Invoke] void DoSomething() { } } } Then I generate the whole solution and... nothing happens on the client project. The Generated_Code folder is empty, and the domain context object for the service is not here. Funny enough, if I add a new item of type Authentication domain service, it works as expected: the file RIAServicesLibrary1.Web.g.cs is created on the client project, containing the AuthenticationDomainService1 class as expected. So what's happening here? Am I doing something wrong? Note: I am using Visual Studio 2010 Ultimate RTM and WCF RIA services 1.0.

  • Crosstab/Cube/Pivot Components for Delphi

    - by Anagoge
    I'm looking for a Delphi VCL crosstab/cube/pivotcube/olap grid component for Delphi 2009, 2010, or XE. I'm willing to sacrifice advanced features to get something open/free (or very cheap if I must) to make it easier to collaborate with any future developers without anyone having to purchase more components than I already use, since this will just be used in one screen. If there isn't anything appropriate out there, I may try to implement something simple on my own. I can live with some fairly basic features: drag and drop to configure dimensions, sort by a column, allow totals/min/max for a column, and (optionally) expand/collapse or drill down to sub-categories. Blazing performance and enterprise scalability are not required, since there should be less than 2000 source rows. There appear to be several decent options in the commercial space (ExpressPivotCube, FastCube, HierCube), but they are all a few hundred dollars. This project already uses existing installations of Excel 2007 and SQL Server 2005/2008, so I might consider leveraging those, though I'd prefer a native Delphi component, if possible. There are also the very old Decision Cube components included in Delphi's Source\xtab directory, but they apparently no longer support unicode compilers (Delphi 2009+), since I got dozens of unicode-related compilation errors while test compiling that source in Delphi XE. Those components also still link to the long-deprecated BDE! Has anyone modified Decision Cube to support unicode/pure-TDataSet? The online tutorials I found were incomplete and silent on the dozens of BDE/unicode compilation errors I see, so I might have to tackle that on my own. Does anyone have suggestions where to start for a free/cheap basic crosstab/pivot grid component?

  • How do I encapsulate form/post/validation[/redirect] in ViewUserControl in ASP.Net MVC 2

    - by paul
    What I am trying to achieve: encapsulate a Login (or any) Form to be reused across site post to self when Login/validation fails, show original page with Validation Summary (some might argue to just post to Login Page and show Validation Summary there; if what I'm trying to achieve isn't possible, I will just go that route) when Login succeeds, redirect to /App/Home/Index also, want to: stick to PRG principles avoid ajax keep Login Form (UserController.Login()) as encapsulated as possible; avoid having to implement HomeController.Login() since the Login Form might appear elsewhere All but the redirect works. My approach thus far has been: Home/Index includes Login Form: <%Html.RenderAction("Login","User");%> User/Login ViewUserControl<UserLoginViewModel> includes: <%=Html.ValidationSummary("") % using(Html.BeginForm()){} includes hidden form field "userlogin"="1" public class UserController : BaseController { ... [AcceptPostWhenFieldExists(FieldName = "userlogin")] public ActionResult Login(UserLoginViewModel model, FormCollection form){ if (ModelState.IsValid) { if(checkUserCredentials()) { setUserCredentials() return this.RedirectToAction<Areas.App.Controllers.HomeController>(x = x.Index()); } else { return View(); } } ... } Works great when: ModelState or User Credentials fail -- return View() does yield to Home/Index and displays appropriate validation summary. (I have a Register Form on the same page, using the same structure. Each form's validation summary only shows when that form is submitted.) Fails when: ModelState and User Credentials valid -- RedirectToAction<>() gives following error: "Child actions are not allowed to perform redirect actions." It seems like in the Classic ASP days, this would've been solved with Response.Buffer=True. Is there an equivalent setting or workaround now? Btw, running: ASP.Net 4, MVC 2, VS 2010, Dev/Debugging Web Server I hope all of that makes sense. So, what are my options? Or where am I going wrong in my approach? tia!

  • Is there any better IDOMImplementation other than MSXML?

    - by Chau Chee Yang
    There are 3 IDOMImplementation available in Delphi: MSXML Xerces XML ADOM XML v4 MSXML is the default IDOMImplementation. My test is count the time need to load a 10MB xml file. I use a Delphi unit generated from a XSD using XML data binding to load the xml file. This unit has 3 common function: function Getmenubar(Doc: IXMLDocument): IXMLMenubarType; function Loadmenubar(const FileName: WideString): IXMLMenubarType; function Newmenubar: IXMLMenubarType; I learn from the web that some comment that MSXML's overhead is high that it doesn't perform if compare to other XML parser. However, my study shows that MSXML is the best among others. Xerces XML 2nd and ADOM XML v4 the worst: MSXML - 0.6410 seconds Xerces XML - 2.4220 seconds ADOM XML v4 - 67.50 seconds I also come across with OmniXML that claim to have much better performance compare to MSXML but I never success using it with the unit generated by XML data binding. Is there any other vendor that implement IDOMImplementation of Delphi that work much better than MSXML? I am using Delphi 2010 and Windows 7.

  • How to keep text inside a circle using Cairo?

    - by miguelrios
    I a drawing a graph using Cairo (pycairo specifically) and I need to know how can I draw text inside a circle without overlapping it, by keeping it inside the bounds of the circle. I have this simple code snippet that draws a letter "a" inside the circle: ''' Created on May 8, 2010 @author: mrios ''' import cairo, math WIDTH, HEIGHT = 1000, 1000 #surface = cairo.PDFSurface ("/Users/mrios/Desktop/exampleplaces.pdf", WIDTH, HEIGHT) surface = cairo.ImageSurface (cairo.FORMAT_ARGB32, WIDTH, HEIGHT) ctx = cairo.Context (surface) ctx.scale (WIDTH/1.0, HEIGHT/1.0) # Normalizing the canvas ctx.rectangle(0, 0, 1, 1) # Rectangle(x0, y0, x1, y1) ctx.set_source_rgb(255,255,255) ctx.fill() ctx.arc(0.5, 0.5, .4, 0, 2*math.pi) ctx.set_source_rgb(0,0,0) ctx.set_line_width(0.03) ctx.stroke() ctx.arc(0.5, 0.5, .4, 0, 2*math.pi) ctx.set_source_rgb(0,0,0) ctx.set_line_width(0.01) ctx.set_source_rgb(255,0,255) ctx.fill() ctx.set_source_rgb(0,0,0) ctx.select_font_face("Georgia", cairo.FONT_SLANT_NORMAL, cairo.FONT_WEIGHT_BOLD) ctx.set_font_size(1.0) x_bearing, y_bearing, width, height = ctx.text_extents("a")[:4] print ctx.text_extents("a")[:4] ctx.move_to(0.5 - width / 2 - x_bearing, 0.5 - height / 2 - y_bearing) ctx.show_text("a") surface.write_to_png ("/Users/mrios/Desktop/node.png") # Output to PNG The problem is that my labels have variable amount of characters (with a limit of 20) and I need to set the size of the font dynamically. It must fit inside the circle, no matter the size of the circle nor the size of the label. Also, every label has one line of text, no spaces, no line breaks. Any suggestion?

  • Parsing third-party XML

    - by mare
    What path would you took to parse a large XML file (2MB - 20 MB or more), that does not have a schema (I cannot infer one with XSD.exe because the file structure is odd, check the snippet below)? Options 1) XML Deserialization (but as said, I don't have a schema and XSD tool complains about the file contents), 2) Linq to XML, 3) loading into XmlDocument, 4) Manual parsing with XmlReader & stuff. This is XML file snippet: <?xml version="1.0" encoding="utf-8"?> <xmlData date="29.04.2010 12:09:13"> <Table> <ident>079186</ident> <stock>0</stock> <pricewotax>33.94000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> <Table> <ident>079190</ident> <stock>1</stock> <pricewotax>10.50000000</pricewotax> <discountpercent>0.00000000</discountpercent> <pricebyquantity> <Table> <quantity>5</quantity> <pricewotax>10.00000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> <Table> <quantity>8</quantity> <pricewotax>9.00000000</pricewotax> <discountpercent>0.00000000</discountpercent> </Table> </pricebyquantity> </Table> </xmlData>

  • Terrible DotNetNuke performance

    - by Peter Bridger
    I'm involved with a project using DotNetNuke version 05.01.04 Community Edition. We are building our new Intranet using it, but performance is terrible. We have five people adding pages and content to it and every 15-30 seconds they experience a pause of 10 seconds or longer before the system continues and the next screens loads. The server is Windows 2003, 3.8GHz with 1GB of RAM. I'm told by our server admin that the CPU and memory performance don't appear to be the bottleneck. We currently have 350 pages in the system, we a plan to add 1000. So we need to resolve this performance problem so that we can enter content and so we can go live. I just can't see where the bottleneck is. Is there a good why to determine the bottleneck when using DotNetNuke? Modules installed Publish:Engage (Not currently in use) Page Blaster (Doesn't appear to providing caching when users logged in using Integrated Authentication) SimpleGallery XMod Content Manager IIS Setup Application recycling completely disabled (Apart from a 2am recycle) New findings: 18th March 2010 The main bottleneck was due to version 5.1.4 having a bug which caused 1300 database roundtrips on an average page, due to broken database in-memory caching. We've upgraded to 5.2.4 which has resolved this bottleneck. Now the next biggest bottleneck is the navigation. We've used both DDR:Menu and DDN:Nav, but both have a major impact on performance. Is there a navigation interface out there that doesn't drain performance so badly?

  • Snippets between desktop and laptop

    - by Jamie F
    The Situation: At work, I have a nice beefy desktop running Windows Server 2008 R2 (SharePoint dev machine). My handy ThinkPad is right next to it. Every once in a while I'd like to cut and paste or share something (usually text) between the machines: for example, I might be headed out and I'd like to take send the URL I'm reading from the desktop to the laptop. Of course I can create a share or use the Admin shares and create files to get stuff back and forth, but that seems heavyweight for what I'm thinking of. I'm thinking more along the lines of sending myself an IM. How do you get little things from machine to machine? Keep a shared folder pinned to the taskbar? Send an email to yourself? Bookmark sync? While on it, I'm looking for a decent multiple clipboard handler: maybe these two functions are combined in some nice little utility? I suspect I'm missing something simple here... Thanks...

  • EF4 Generate Database

    - by shaneseaton
    Hi, I am trying my hardest to find the simplest way to create a basic "model first" entity framework example. However I am struggling with the actually generation of the database, particularly the running of the SQL against the database. Tools Visual Studio 2010 SQL Server 2008 Express Process Create a new class project Add a new Server-Database item (mdf) named "Database1.mdf" to the project Add an empty ADO.net Entity Model Create a simple entity (Person: Id, Name) Generate the Script selecting the Database1 connection created for me by visual studio Right click the script editor and select the "Execute SQL..." option Log in to SQLEXPRESS This is where is falls over saying it cant find a database name "Database1". The "problem" is that the SQL server has not had Database1 attached to it. I am 100% positive that Visual Studio use to attach a database to SQLExpress when it created a new database (Step 2). This appears to not be the case any more (even the beta of VS2010 did it). Can someone confirm this? or tell me how to get this to happen? Is there a way that I can modify the TSQL script to use an un-attached database. ie a file. I know I can use SQL Management Studio or sqlcmd to attach the database, but I would ideally like to avoid the solutions as I would like to see the cleanest method of just using visual studio. Ideal Solutions (in order of most prefered) Get visual studio to attach the newly created database Modify the generated SQL to point to file Thanks in advance.

  • USB Barcode Scanner and WM_KEYDOWN

    - by Bryce Fischer
    I am trying to write a program that can will read a barcode scanner. In addition, I need it to read the input even when the application is not the window in focus (i.e., running in system tray, etc). I found this article, titled Distinguishing Barcode Scanners from the Keyboard in WinForms, that seems to solve the exact problem. It is working pretty good, it detects my device and handles the WM_INPUT message. However, it is checking to see if the RAWINPUT.keyboard.Message is WM_KEYDOWN (0x100). It never seems to receive this. The only line of code I've altered in the code provided in the article is adding a Console.Out.WriteLine to output the actual values of that message: Console.Out.WriteLine("message: {0}", raw.keyboard.Message.ToString("X")); if (raw.keyboard.Message == NativeMethods.WM_KEYDOWN) { .... Here is what it outputs: message: B message: 1000B message: 3 message: 10003 message: 8 message: 10008 message: 3 message: 10003 message: 5 message: 10005 message: 3 message: 10003 message: 8 message: 10008 message: 8 message: 10008 message: 4 message: 10004 message: 9 message: 10009 message: 9 message: 10009 message: 3 message: 10003 The value I'm expecting to receive when this completes correctly is: 257232709 Which I verified by scanning to notepad. I don't know if the Operation System is relevant here, but I figured I should mention that I'm running this in Windows 7 64 and Visual Studio 2010 and .NET Framework 3.5. Scanner is a USB Barcode Scanner, Symbol LS2208, setup as "HID KEYBOARD EMULATION"

  • doublechecking: no db-wide 'unicode switch' for sql server in the foreseeable future, i.e. like Orac

    - by user72150
    Hi all, I believe I know the answer to this question, but wanted to confirm: Question Does Sql server (or will it in the foreseeable future), offer a database-wide "unicode switch" which says "store all characters in unicode (UTF-16, UCS-2, etc)", i.e. like Oracle. The Context Our application has provided "CJK" (Chinese-Japanese-Korean) support for years--using Oracle as the db store. Recently folks have been asking for the same support in sql server. We store our db schema definition in xml and generate the vendor-specific definitions (oracle, sql server) using vendor-specific xsl. We can make the change easily. The problem is for upgrades. Generated scripts would need to change the column types for 100+ columns from varchar to nvarchar, varchar(max) to nvarchar(max), etc. These changes require dropping and recreating indexes and foreign keys if the any indexes/fk's exist on the column. Non-trivial. Risky. DB-wide character encodings for us would eliminate programming changes. (I.e. we would not to change the column types from varchar to nvarchar; sql server would correctly store unicode data in varchar columns). I had thought that eventually sql server would "see the light" and allow storing unicode in varchar/clob columns. Evidently not yet. Recap So just to triple check: does mssql offer a database-wide switch for character encoding? Will it in SQL2008R3? or 2010? thanks, bill

  • OData / WCF Data Service - HTTP 500 Error

    - by Eric
    I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

  • Math operations in nHibernate Criteria Query

    - by Richard Tasker
    Dear All, I am having troubles with a nHibernate query. I have a db which stores vehicle info, and the user is able to search the db by make, model, type and production dates. Make, model & type search is fine, works a treat, it is the productions dates I am having issues with. So here goes... The dates are stored as ints (StartMonth, StartYear, FinishMonth, FinishYear), when the end-user selects a date it is passed to the query as an int eg 2010006 (2010 * 100 + 6). below is part of the query I am using, FYI I am using Lambda Extensions. if (_searchCriteria.ProductionStart > 0) { query.Add<Engine>(e => ((e.StartYear * 100) + e.StartMonth) >= _searchCriteria.ProductionStart); } if (_searchCriteria.ProductionEnd > 0) { query.Add<Engine>(e => ((e.FinishYear * 100) + e.FinishMonth) <= _searchCriteria.ProductionEnd); } But when the query runs I get the following message, Could not determine member from ((e.StartYear * 100) + e.StartMonth) Any help would be great, Regards Rich

  • Can the same ssh key be used to access two different users on the same server?

    - by Nick
    I have an new ubuntu (hardy 8.04) server, it has two users, User1 and User2. User1 is listed in sudoers. I appended my public ssh key to authorized_keys in /home/user1/.ssh/authorized_keys, changed the permissions on user1/.ssh/ to 700 and user1/.ssh/authorized_keys to 600 and both file and folder are owned my User1. Then added I User1 to sshd_config (AllowUsers User1). This works and I can login into User1 debug1: Offering public key: /Users/nick/.ssh/id_rsa debug1: Server accepts key: pkalg ssh-rsa blen 277 debug1: Authentication succeeded (publickey). debug1: channel 0: new [client-session] debug1: Entering interactive session. Last login: Mon Mar 15 09:51:01 2010 from 86.141.61.197 I then copied the authorized_keys file to /home/user2/.shh/ and changed the permissions and ownership and added User2 to AllowUsers in sshd_config (AllowUsers User1 User2). Now when I try to login to User2 it will not authenticate the same public key. debug1: Offering public key: /Users/nick/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /Users/nick/.ssh/identity debug1: Trying private key: /Users/nick/.ssh/id_dsa debug1: No more authentication methods to try. Permission denied (publickey). Am I missing something fundamental about the way ssh works? Thanks in advance, Nick

  • AuthResend query string being appended to URL

    - by Alastair Pitts
    One of our clients is having an issue where POSTBACK seems to be broken when they connect to our Sharepoint application. When they navigate to a URL, an erroneous query string gets appended to the URL, so the end of the URL becomes: .../default.aspx&AuthResend1908BC2350124b5095AB75012FA405BA this isn't something that appears on any other clients computers or ours internally. This is the only difference and it seems to be breaking their pages. I had a quick Google and it seems that it's to do with a Microsoft ISA server, but I have no experience with that. Is this a bug or setting on their ISA server?

  • Mac Joining Active Directory Still Prompts For Authentication

    - by David Potter
    My Mac is joined to an Active Directory domain. What I expected to see was the same ease of access to file shares and internal websites that Windows computers joined to the domain experience (i.e., no authentication needed; it just uses Windows Integrated Authentication). Instead I am asked for credentials each time I try to access those shares and protected websites (e.g. SharePoint). Is this normal behavior, or is something wrong with my Mac that it prompts me for my username and password for the domain when I access Windows file shares or intranet sites protected by NTLM/Kerberos? Machines include: MacBook Pros running Mountain Lion MacBook Pros running Lion MacServer running Lion Server

  • How does GMail implement Comet?

    - by Morgan Cheng
    With the help of HttpWatch, I tried to figure out how GMail implement Comet. I Login in GMail with two account, one in IE and the other in Firefox. Chatting in GTalk in GMail with some magic words like "WASSUP". Then, I logoff both GMail accounts, filter any http content without "WASSUP" string. The result shows which HTTP request is the streaming channel. (Note: I have to logoff. Otherwise, never-ending HTTP would not show content in HttpWatch.) The result is interesting. The URL for stream channel is like: https://mail/channel/bind?VER=8&at=xn3j33vcvk39lkfq..... There is no surprise that GMail do Comet in IE with IFRAME. The Http content starts with " Originally, I guessed that GMail do Comet in Firefox with multipart XmlHttpRequest. To my surprise, the response header doesn't have "multipart/x-mixed-replace" header. The response headers are as below: HTTP/1.1 200 OK Content-Type: text/plain; charset=utf-8 Cache-Control: no-cache, no-store, max-age=0, must-revalidate Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Date: Sat, 20 Mar 2010 01:52:39 GMT X-Frame-Options: ALLOWALL Transfer-Encoding: chunked X-Content-Type-Options: nosniff Server: GSE X-XSS-Protection: 0 Unfortunately, the HttpWatch doesn't tell whether a HTTP request is from XmlHttpRequest or not. The content is not HTML but JSON. It looks like a response for XHR, but that would not work for Comet without multipart/x-mixed-replace, right? Is there any way else to figure out how GMail implement Comet? Thanks.
