• How to check misspelled email during user registration

  - by Nulldevice

  I use an email registration and confirmation in my project (yes, I know about OpenID. In my counry, a main email service lack it). Sometimes users misspell their email addresses. I know about this due to "message could not be delivered" letters in a mailbox. A misspelled address is absolutely correct, because I check it with a regular expression - say, [email protected] intstead of [email protected]. And I do not want to duplicate a email field in a registration form (who likes it?). Request processing routine cannot wait for email delivery - it could take an unpredictable time. So, my script will return to user a confirmation message "An email was sent". And the user will wait for it forever (of cause, not - he/she will turn to an alternative project with a more perfect registration system). Does someone knows how it can be improved (in any programming language)?

• How to Force iPhone to Check Orientation

  - by Shannon A.

  Here's the problem: View Controller #1 only runs in the two landscape orientations. View Controller #2 runs in any orientation. When view controller #2 is pushed on top of view controller #1 (using presentModalViewController:animated:, as it happens), there's no check for orientation. Instead, VC #2 just assumes the orientation is whichever landscape orientation VC #1 is currently in. This behavior is incorrect if the user happens to be holding the iPhone in a portrait orientation, despite the fact that he's viewing VC #1 where it's not supported. This can easily happen during startup, so it's not just a theoretical question. Is there any way to tell VC #2 to recheck what it's orientation actually is? If so, where would it be best placed? viewDidLoad?

• How to check if a generic type definition inherits from another generic type definition

  - by Anne

  I'm trying to check whether an open generic type definition implements some open generic interface. Look at the sample below: public interface IService<T> { } public class ServiceImpl<T> : IService<T> { } private static bool OpenGenericTypeImplementsOpenGenericInterface( Type derivedType, Type interfaceType) { return derivedType.GetInterfaces().Contains(interfaceType); } [TestMethod] public void Verify() { Type openGenericImplementation = typeof(ServiceImpl<>); Type expectedInterfaceType = typeof(IService<>); bool implDoesImplementInterface = OpenGenericTypeImplementsOpenGenericInterface( openGenericImplementation, expectedInterfaceType); // This assert fails. Why? Assert.IsTrue(implDoesImplementInterface); } I found out that the returned type from the Type.GetInterfaces() method does not match the type returned from typeof(IService<>). I can't figure out why that is and how to correctly validate whether some generic type definition inherits or implements some other generic type definition. What's going on here and how do I solve fix this problem?

• check if(country == @"(null)" doesn't work

  - by Sean

  hi all, I got the problem that the if-statement doesn't work. After the first code line the variable contains the value "(null)", because the user who picked the contact from his iphone address book doesn't set the country key for this contact, so far so good. but if I check the variable, it won't be true, but the value is certainly "(null)"... does someone have an idea? NSString *country = [NSString [the dict objectForKey:(NSString *)kABPersonAddressCountryKey]]; if(country == @"(null)") { country = @""; } thanks in advance sean

  - by StealthRT

  Hey all, this is the code i have to check for a day thats equal to the list of days in the comma seperated list: for(var i = 0; i < daysHidden.length; i++){ if (daysHidden[i] == d.getDate()); { alert(daysHidden[i] + '=' + d.getDate()); } } the daysHidden = 1 (its the only thing in the list April 1st is already gone and todays the 2nd so 1 is the only one in the list) and d.getDate() has 1-30 (for april) When i run the code, however, it keeps looping through the if code when it should only loop once (when it finds that 1=1 However, i keep getting the alert box that says: 1=1 1=2 1=3 etc.... 1=30 So i do not know what i am doing incorrect? I already tried putting them as strings: if (daysHidden[i].ToString == d.getDate().ToString); But that doesnt seem to work.... Any help would be great :) David

• jQuery: check all checkboxes

  - by pcampbell

  Consider this scenario: <asp:CheckBoxList> in a master page. the goal is to have all checkboxes in this list to be checked on page load. there are many checkbox lists on the page. The markup: <asp:CheckBoxList runat="server" ID="chkSubscriptionType" DataSourceID="myDS" CssClass="boxes" DataTextField="Name" DataValueField="Name" /> renders to: <input id="ctl00_cphContent_chkSubscriptionType_0" type="checkbox" name="ctl00$cphContent$chkSubscriptionType$0" /> Question: how can you use jQuery to check all boxes in this asp:CheckBoxList on document.ready? I see samples everywhere, but naming convention used by the master page throws off the samples in other places.

• Intellij Idea 9, what folders to check into (or not check into) source control?

  - by Benju

  Our team has just moved from Netbeans to Intellij 9 Ultimate and need to know what files/folders should typically be excluded from source control as they are not "workstation portable" ie: they reference paths that only exist on one user's computer. As far as I can tell Intellij wants to ignore most of the .idea project including .idea/artifacts/* .idea/inspectionProfiles/* .idea/copyright/* .idea/dataSources.ids .idea/dataSources.xml .idea/workspace.xml However it seems to want to check in the .iml files that exist in each module's root directory. I originally checked in the entire .idea directory via the command line which is obviously not aware of what "should" be ignored by Idea. Is the entire .idea directory typically ignored?

• I-Phone: Trying to check an Array for an item based on a string produced

  - by MB

  Hello! I'm writing a program that will concatenate a string based on letters, and then check an array to see if that string exists. If it does, then it will print a line in IB saying so. I've got all the ins-and-outs worked out, save for the fact that the simulator keeps crashing on me! Here's the code: -(IBAction)checkWord:(id)sender { NSMutableArray *wordList = [NSMutableArray arrayWithObjects:@"BIKE", @"BUS", @"BILL", nil]; if([wordList containsObject:theWord]) { NSString *dummyText = [[NSString alloc] initWithFormat:@"%@ is a real word.", theWord]; checkText.text = dummyText; [dummyText release]; } } "theWord" is the string that is being referenced against the Array to see if it matches an item contained within it. In this case "BIKE" is 'theWord'. Thank you for your help in advance! -MB

• Programatically check whether a drive letter is a shared/network drive

  - by Philip Daubmeier

  Hi SO community! I searched a while but found nothing that helped me. Is there a way to check whether a drive letter stands for a shared drive/network drive or a local disc in python? I guess there is some windows api function that gives me that info, but I cant find it. Perhaps there is even a method already integrated in python? What I am looking for is something with this or similar behaviour: someMagicMethod("C:\") #outputs True 'is a local drive' someMagicMethod("Z:\") #outputs False 'is a shared drive' That would help me as well: someMagicMethod2() #outputs list of shared drive letters Thanks a lot in advance!

• bash script to check running process

  - by elasticsecurity

  I wrote a bash-script to check if a process is running. It doesn't work since the ps command always returns exit code 1. When I run the ps command from the command-line, the $? is correctly set, but within the script it is always 1. Any idea? #!/bin/bash SERVICE=$1 ps -a | grep -v grep | grep $1 > /dev/null result=$? echo "exit code: ${result}" if [ "${result}" -eq "0" ] ; then echo "`date`: $SERVICE service running, everything is fine" else echo "`date`: $SERVICE is not running" fi Bash version: GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu)

• Jquery username check

  - by Sergio

  I'm using this Jquery function for available username check. How can I fire this Jquery function only if the username field is greater of 5 characters?

• What's the best way to check that environment variables are set in Unix shellscript

  - by AndrewR

  I've got a few Unix shell scripts where I need to check that certain environment variables are set before I start doing stuff, so I do this sort of thing: if [ -z "$STATE" ]; then echo "Need to set STATE" exit 1 fi if [ -z "$DEST" ]; then echo "Need to set DEST" exit 1 fi which is a lot of typing. Is there a more elegant idiom for checking that a set of environment variables is set? EDIT: I should mention that these variables have no meaningful default value - the script should error out if any are unset.

• How Can I Check an Object to See its Type and Return A Casted Object

  - by Russ Bradberry

  I have method to which I pass an object. In this method I check it's type and depending on the type I do something with it and return a Long. I have tried every which way I can think of to do this and I always get several compiler errors telling me it expects a certain object but gets another. Can someone please explain to me what I am doing wrong and guide me in the right direction? What I have tried thus far is below: override def getInteger(obj:Object) = { if (obj.isInstanceOf[Object]) null else if (obj.isInstanceOf[Number]) (obj:Number).longValue() else if (obj.isInstanceOf[Boolean]) if (obj:Boolean) 1 else 0 else if (obj.isInstanceOf[String]) if ((obj:String).length == 0 | (obj:String) == "null") null else try { Long.parse(obj:String) } catch { case e: Exception => throw new ValueConverterException("value \"" + obj.toString() + "\" of type " + obj.getClass().getName() + " is not convertible to Long") } }

• rdlc - phantom page break, what to check?

  - by Antonio Nakic Alfirevic

  I have a RDLC report which has some controls on the first page, which are inside a rectangle and which display ok. Beneath the rectangle, i have a matrix, which spans more than one page both in width and in height. I want the matrix to start rendering on the second page. If I enable "insert break before" on the matrix, there is an extra blank page before the matrix(in print layout), which is my problem. If I reduce the amount of data, so the matrix does not span more than one page in width, there is no blank page, and all is well. I checked the Page and Body sizes, they are ok. Any tips? This has been driving me crazy all day, what can I check? Thx

• ASP.net MVC - Check status request

  - by vdhant

  Hi guys Just wondering if its possible to get the status of a request from another request? To help provide some context, I want to use ajax to upload some files to the server. When the upload is started I want triggered another ajax request that checks to see how much of the file has been uploaded (or in other words how big was the other request and how far through receiving the request is the server). I was thinking that I could use a guid or something similar to ensure that I am checking the status of the right request. But how do I check the status of another request??? Cheers Anthony

• Linq sql Attach, Update Check set to Never, but still Concurrency conflicts

  - by remdao

  In the dbml designer I've set Update Check to Never on all properties. But i still get an exception when doing Attach: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." This approach seems to have worked for others on here, but there must be something I've missed. using(TheDataContext dc = new TheDataContext()) { test = dc.Members.FirstOrDefault(m => m.fltId == 1); } test.Name = "test2"; using(TheDataContext dc = new TheDataContext()) { dc.Members.Attach(test, true); dc.SubmitChanges(); }

• how to check if the enddate is after the startdate in a zend form

  - by murze

  I have a zend form with a start- and an endate. $form = new Zend_Form(); $form->setName($this->formName) ->setMethod('post'); $feStartdate = new Zend_Form_Element_Text('startdate'); $feEnddate = new Zend_Form_Element_Text('enddate'); $form->addElement($feStartDate) ->addElement($feEndDate) ->addElement('submit', 'submit', array('label' => 'Save')); I assume I must write a custom validator for to check this. How would this custom validator look like and how can I call it? I assume something like $feEnddate->addValidator('dateComesAfter', $feStartDate)

• T-SQL query to check number of existences

  - by abatishchev

  I have next approximate tables structure: accounts: ID INT, owner_id INT, currency_id TINYINT related to clients: ID INT and currency_types: ID TINYINT, name NVARCHAR(25) I need to write a stored procedure to check existence of accounts with specific currency and all others, i.e. client can have accounts in specific currency, some other currencies and both. I have already written this query: SELECT ISNULL(( SELECT 1 WHERE EXISTS ( SELECT 1 FROM [accounts] AS A, [currency_types] AS CT WHERE A.[owner_id] = @client -- sp param AND A.[currency_id] = CT.[ID] AND CT.[name] = N'Ruble' )), 0) AS [ruble], ISNULL(( SELECT 1 WHERE EXISTS ( SELECT A.[ID] FROM [accounts] AS A, [currency_types] AS CT WHERE A.[owner_id] = @client AND A.[currency_id] = CT.[ID] AND CT.[name] != N'Ruble' )), 0) AS [foreign] Is it possible to optimize it? I'm new to (T)SQL, so thanks in advance!

• Check if serial port is listening

  - by Hyposaurus

  I have an Arduino sending and receiving instructions with a python script via a serial port. The Arduino takes a button state and when it is pushed it will send a message via serial to a python script and await a response. (via Serial.available()). Works well enough. However if the python script has crashed for whatever reason (ideally it will run in the background, so cant be easily checked) the Arduino will wait forever and even on a script restart will we unavailable. Is there a way for my Arduino to check if there is something listening on the serial port? (and alert me with flashing lights etc if not) or is this not how serial works? Worst case I guess I could use a timeout, although that is not ideal.

• Any way to trigger interface orientation check?

  - by Johnny Tee

  My app is going from a flipside view (only one orientation) to its main view (can have any sort of orientation. When I go from flipside back to main view, the main view's orientation is not checked and changed immediately. I need a way to trigger the built in orientation check that happens in willRotateToInterfaceOrientation so that the orientation is correct when the user goes from flipside view to main view. Any help is appreciated. I saw another question about this but didn't see a definitive answer. Thanks!
