  • Can I assign a object to a integer variable?

    - by AKN
    Let say I have a object. I'm assigning that to an integer. MyClass obj1 = 100;//Not valid Let's say, I have a parameterized constructor which accepts an integer. MyClass(int Num) { // .. do whatever.. } MyClass obj1 = 100;//Now, its valid Likewise on any circumstance, does the vice-versa becomes valid?!. eg) int Number = obj1;//Is it VALID or can be made valid by some tweeks

  • What is the RFC complicant and working regular expression to check if a string is a valid URL

    - by bestis
    There is question by the almost the same name already: What is the best regular expression to check if a string is a valid URL I don't understand this stackoverflow. It seems like I need reputation to comment an answer. As I don't have it, I don't know how to tell/ask that the proposed solution doesn't seem to work. So I'm forced to make a new question and ask for the solution this way? But that regexp seems to fail in input which has IPv6 address in it: For example facebook's IPv6 address: http://2620:0:1cfe:face:b00c::3/ Also link to localhost fails: http://::1/ Or is PHP to blame? /** * Validate URL - RFC 3987 (IRI) * * http://stackoverflow.com/questions/161738/what-is-the-best-regular-expression-to-check-if-a-string-is-a-valid-url * * @param string $str_url * @return boolean

  • Explained: EF 6 and “Could not determine storage version; a valid storage connection or a version hint is required.”

    - by Ken Cox [MVP]
    I have a legacy ASP.NET 3.5 web site that I’ve upgraded to a .NET 4 web application. At the same time, I upgraded to Entity Framework 6. Suddenly one of the pages returned the following error: [ArgumentException: Could not determine storage version; a valid storage connection or a version hint is required.]    System.Data.SqlClient.SqlVersionUtils.GetSqlVersion(String versionHint) +11372412    System.Data.SqlClient.SqlProviderServices.GetDbProviderManifest(String versionHint) +91    System.Data.Common.DbProviderServices.GetProviderManifest(String manifestToken) +92 [ProviderIncompatibleException: The provider did not return a ProviderManifest instance.]    System.Data.Common.DbProviderServices.GetProviderManifest(String manifestToken) +11431433    System.Data.Metadata.Edm.Loader.InitializeProviderManifest(Action`3 addError) +11370982    System.Data.EntityModel.SchemaObjectModel.Schema.HandleAttribute(XmlReader reader) +216 A search of the error message didn’t turn up anything helpful except that someone mentioned that the error messages was bogus in his case. The page in question uses the ASP.NET EntityDataSource control, consumed by a Telerik RadGrid. This is a fabulous combination for putting a huge amount of functionality on a page in a very short time. Unfortunately, the 6.0.1 release of EF6 doesn’t support EntityDataSource. According to the people in charge, support is planned but there’s no timeline for an EntityDataSource build that works with EF6.  I’m not sure what to do in the meantime. Should I back out EF6 or manually wire up the RadGrid? The upshot is that you might want to rethink plans to upgrade to Entity Framework 6 for Web forms projects if they rely on that handy control. It might also help to spend a User voice vote here:  http://data.uservoice.com/forums/72025-entity-framework-feature-suggestions/suggestions/3702890-support-for-asp-net-entitydatasource-and-dynamicda

  • How do I obtain a valid DNS resolution given just an IP address?

    - by Dee Newcum
    Is there a publicly-available DNS server somewhere that will respond to requests like: 74_125_225_50.anyip.com And will return 74.125.225.50 for the above request? That is, every single possible IP address can queried by name instead of number. http://ipq.co/ is close to what I'm looking for, but it requires you to first register an IP address before you can query its DNS name. I want a service that does a straightforward mapping from domain name to IP address. Why do I want to do this? I have a program that we use at work that requires a DNS lookup, but I need to be able to give it bare IP addresses. (long story... it's a server that I don't control, so I can't work around it using /etc/hosts)

  • Random BSODs on Win7 boot. Can't find a valid reason.

    - by 0plus1
    Hi, I bought and assembled a new pc: ASUS m4a785td-v EVO AMD x4 620 OCZ Black Edition 2x 2gb WD 500gb sata Win7 Ultimate 64bit fresh install BSOD on boot. Formatted, reinstalled, BSOD on install. Ran memtest - no errors. Ran Win7 install in safe mode. Installed, random BSOD on win7 startup, even in safe mode. Updated BIOS. Ran the win7 memtest (no error), booted after some tries and ran Prime95 blend test for 12 hours straight with no errors at all! When the pc has booted, win7 runs as smooth as possible, I've been playing STALKER for 4 hours straight with not a single hiccup. Using Blue Screen View I can see that every BSOD involves: ntoskrnl.exe Here are the dumps Any help would be greatly appreciated, this thing is driving me crazy.

  • Space a valid delimiter for email addresses in email header?

    - by semanticalo
    Is it syntactically correct to delimit multiple email recipients in the "To" header of an email with spaces only or do I need to use another delimiter (a semicolon or the like)? Example (MIME data reads as follows): Date: Mon, 04 Oct 2010 06:14:16 +0200 From: [email protected] To: [email protected] [email protected] [email protected] Subject: Test Subject The above will be processed by many email processing applications, but I need to know whether it's correct according to standard (RFC). Unfortunately I didn't find anything useful on the internet so far. Thanks a million for your help!

  • Is my Windows 7 x86 license key valid for a x64 installation of Windows?

    - by Kragen
    I've just got a new laptop with Windows 7 x86 Home Premium installed, however I ideally I'd like to be running a 64-bit operating system: Is my Windows license key "generic" (in that it entitles me to install either a x86 or x64 edition of Windows), or does this licence key specific to the x86 version of Windows? Is there any way of me installing and running Windows 7 Home Premium x64 using my x86 license key?

  • how can I manage user-dependent variables, that are valid on the whole domain ( Win Server 2003)

    - by Stephane R.
    Hello I am working on a system that needs a user-dependent variable, the user in on Windows XP and is connected to Windows Server 2003. I cannot save this variable in the registry of the local machine under HKCU, because the users are likely to exchange their machines. This variable must be accessible on the whole domain. Do you have any idea of implementing this ? Are there WMI features that may help me ?

  • Windows 8.1 wants to format a USB stick with an unusual but valid GPT partitioning scheme, why?

    - by DonGar
    I have a USB stick formatted with GPT partitions. Some of the partitions are ext2, some are ext4, some are custom and funky. However, there is also a standard EFI partition, and a standard vfat partition. In Windows 7, both the EFI partition and the standard VFAT partition are visible and mount normally. But Windows 8.1 prompts to reformat the drive when it's inserted. I'm not surprised if Win 8 hides the EFI partition, but I didn't expect it to prompt for reformatting. I want to leave existing partitions alone, but have a VFAT partition that Windows 7, 8, and 8.1 will mount and display normally. Exactly how does Win 8 decide if a device needs to be formatted?

    - by QXT
    I have been Google'ing my fingers off and simply can not find a working example of how to merge/proxy a OpenLDAP server and windows AD server. Have anyone worked with this before? Any suggestions would be appreciated. The idea is simple: openldap.mydomain.local ---- Linux LDAP Server winad.mydomain.local ---- Windows AD Server Some users are one Linux and some on WinAD. OpenLDAP should search both on login. A working example would be appreciated.

  • Horizontal page curl in iPhone - I have - But Valid ?

    - by sagar
    Hello ! Every one. I was googling for applying horizontal page curl in iPhone. I also tried this, but it wasn't appropriate for me (To change orientation & work in different ori.). I tried to google more. Finally I got a link or link . From Where, I could Understand the horizontal page curl. But when I went to code deeply, I found some confusing points. Let me list down. Please download attached code - it's not my code. ( I am not selling any code, but Direct project link would be better than placing multiple codes here. ) extern NSString *kCAFilterPageCurl; // From QuartzCore.framework is it valid to use internal variable ? ( as it's mentioned - from QuartzCore ) CAFilter *previousFilter = [[CAFilter filterWithType:kCAFilterPageCurl] retain]; Above statement is giving warning ( not error ) - no '+filterWithType:' method found Might be using internal (apple's private) method. [previousFilter setDefaults]; Above statement is giving warning ( not error ) - no '-setDefaults:' method found Might be using internal (apple's private) method. Now My queries. I have above doubts in the project ( that might be using apple's private methods ). Is this code safe for apple store approval ? If 2's answer is wrong, what should be done for horizontal page curl ? In short, I want a horizontal page curl, But Need your suggestions for having the proper solution, which might not trouble me in future. Thanks in advance for your great help. Sagar.

  • Flex through Flash Builder 4; Connecting to a dynamic XML feed: "The response is not a valid XML or

    - by jtromans
    I am learning how to use Flex with Adobe Flash Builder 4 standalone. I am working my through the Adobe Flash Build 4 Bible by David Gassner. This has led me to create my own micro problems to try and solve. I am trying to connect to a dynamix XML feed created by the following aspx page: generate_xml.aspx When I create the data connection through the Data/Service panel, I can pick between XML and HTTP. I figured because the generate_xml.aspx has to generate the XML file first, I should use the HTTP service as opposed to the XML. The HTTP service offers GET, which seems to be the kinda thing I want. However, I am really struggling to do this. I keep getting: "The response is not a valid XML or a JSON string" The actual STATIC generated XML file that is created by this page works perfectly when I save it and manually connect with the XML service. Therefore I know my XML code is properly formatted and contains no other HTML of JavaScript. I figure my problem occurs because the page itself is .aspx, but I cannot work out how to successfully ask Flex to request the output of this page, rather than the page itself.

  • How can I determine if an object or reference has a valid string coercion?

    - by Ether
    I've run into a situation (while logging various data changes) where I need to determine if a reference has a valid string coercion (e.g. can properly be printed into a log or stored in a database). There isn't anything in Scalar::Util to do this, so I have cobbled together something using other methods in that library: use strict; use warnings; use Scalar::Util qw(reftype refaddr); sub has_string_coercion { my $value = shift; my $as_string = "$value"; my $ref = ref $value; my $reftype = reftype $value; my $refaddr = sprintf "0x%x", refaddr $value; if ($ref eq $reftype) { # base-type references stringify as REF(0xADDR) return $as_string !~ /^${ref}\(${refaddr}\)$/; } else { # blessed objects stringify as REF=REFTYPE(0xADDR) return $as_string !~ /^${ref}=${reftype}\(${refaddr}\)$/; } } # Example: use DateTime; my $ref1 = DateTime->now; my $ref2 = \'foo'; print "DateTime has coercion: " . has_string_coercion($ref1) . "\n\n"; print "scalar ref has coercion: " . has_string_coercion($ref2) . "\n"; However, I suspect there might be a better way of determining this by inspecting the guts of the variable in some way. How can this be done better?

  • Creating .ics file from code sometimes givs "The file <filename>[<index>].ics" is not a valid intern

    - by KaJo
    Hi! I am building an ASP site where i use response.write to create an ics file where user can choose open or save dialog for the event. When the user choose open, outlook sometimes gives the error "The file [].ics" is not a valid internet Calender file"? It is always the same event that is written to the response. The code looks like this: this.Response.ContentType = "text/calendar"; this.Response.AddHeader("Cache-Control", "no-cache, must-revalidate"); this.Response.AddHeader("Pragma", "no-cache"); this.Response.Expires = -1; this.Response.AddHeader("Content-disposition", string.Format("attachment; filename={0}.ics",filename)); this.Response.Write("BEGIN:VCALENDAR"); this.Response.Write("\nVERSION:2.0"); this.Response.Write("\nMETHOD:PUBLISH"); this.Response.Write("\nBEGIN:VEVENT"); this.Response.Write("\nType:Single Meeting"); this.Response.Write("\nORGANIZER:MAILTO:" + organizer); this.Response.Write("\nDTSTART:" + startDate.ToUniversalTime().ToString(DateFormat)); this.Response.Write("\nDTEND:" + endDate.ToUniversalTime().ToString(DateFormat)); this.Response.Write("\nLOCATION:" + location); this.Response.Write("\nUID:" + Guid.NewGuid().ToString()); this.Response.Write("\nDTSTAMP:" + DateTime.Now.ToUniversalTime().ToString(DateFormat)); this.Response.Write("\nSUMMARY:" + summary); this.Response.Write("\nDESCRIPTION:" + description); this.Response.Write("\nPRIORITY:5"); this.Response.Write("\nCLASS:PUBLIC"); this.Response.Write("\nEND:VEVENT"); this.Response.Write("\nEND:VCALENDAR"); this.Response.End(); I usually get the error the first time I try to open the event in outlook, and the it works the second time? Does anyone knows how to solve this problem?

  • How do you set up your web server & document's html to correctly serve HTML5 documents?

    - by joedevon
    Maybe I'm an idiot but I don't quite get what goes in the header of my HTML to use XHTML w/ HTML5. Is this still good and we just add the HTML5 tags?: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html dir="ltr" lang="eng" xmlns="http://www.w3.org/1999/xhtml"> Or is it <!DOCTYPE html> or what? Then at A List Apart they say: If you do go with XHTML 5, remember that your server must deliver the documents with a MIME type of application/xhtml+xml or text/xml. Please explain to me as if I was stupid :) what that means in a practical sense? "deliver the documents"? Meaning html? What happens to php? What are the steps required to set up your web server this way?

  • JSF managed bean question

    - by Nitesh Panchal
    Hello, I have one page which uses <ui:insert> called master.xhtml which uses one managedbean named MasterBean.java and its of viewScoped. It calls webservice and has all useful data which will be useful in master.xhtml as well as page which is built using master.xhtml (which uses <ui:include>). When i visit data.xhtml (which uses template as master.xhtml) and which uses managed bean as DataBean.java which is also of view scoped, how do i use MasterBean? If i directly use #{Masterbean.property}, won't it create a new instance again? or will it use the bean which is already in view scope? Also how do i use MasterBean in DataBean in such a way that existing MasterBean's instance is used in DataBean. I don't want new instance of MasterBean in DataBean. Thanks in advance. If i am not clear please let me know.

  • Cross-thread operation not valid: Control accessed from a thread other than the thread it was create

    - by SilverHorse
    I have a scenario. (Windows Forms, C#, .NET) There is a main form which hosts some user control. The user control does some heavy data operation, such that if I directly call the Usercontrol_Load method the UI become nonresponsive for the duration for load method execution. To overcome this I load data on different thread (trying to change existing code as little as I can) I used a background worker thread which will be loading the data and when done will notify the application that it has done its work. Now came a real problem. All the UI (main form and its child usercontrols) was created on the primary main thread. In the LOAD method of the usercontrol I'm fetching data based on the values of some control (like textbox) on userControl. The pseudocode would look like this: //CODE 1 UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") <<======this gives exception { //Load data corresponding to "MyName". //Populate a globale variable List<string> which will be binded to grid at some later stage. } } The Exception it gave was Cross-thread operation not valid: Control accessed from a thread other than the thread it was created on. To know more about this I did some googling and a suggestion came up like using the following code //CODE 2 UserContrl1_LOadDataMethod() { if(InvokeRequired) // Line #1 { this.Invoke(new MethodInvoker(UserContrl1_LOadDataMethod)); return; } if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be binded to grid at some later stage } } BUT BUT BUT... it seems I'm back to square one. The Application again become nonresponsive. It seems to be due to the execution of line #1 if condition. The loading task is again done by the parent thread and not the third that I spawned. I don't know whether I perceived this right or wrong. I'm new to threading. How do I resolve this and also what is the effect of execution of Line#1 if block? The situation is this: I want to load data into a global variable based on the value of a control. I don't want to change the value of a control from the child thread. I'm not going to do it ever from a child thread. So only accessing the value so that the corresponding data can be fetched from the database.

  • SSAS deployment error: Internal error: Invalid enumeration value. Please call customer support! is not a valid value for this element.

    - by Kevin Shyr
    The first search on this error yielded some blog posts that says to check SQL server version.  It suggested that I couldn't deploy a SSAS project originally set for SSAS 2008 to a SSAS 2008 R2, which didn't make sense to me.  Combined with the fact that the error message was telling me to call customer support.  Why do I need to call customer support unless something catastrophic happened?Turns out that one of the file on the SQL server is corrupt.  I could simply delete the database on the SSAS server and re-run deployment.  Problem solved.SSAS errors in visual studio: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Error      10           Internal error: Invalid enumeration value.
