• ViewStateMode property in Asp.Net 4.0

  - by AspOnMyNet

  I haven’t yet started learning Asp.Net 4.0, but I did read a bit on ViewState, where there is a new property ViewStateMode. In earlier versions of Asp.Net, if parent control had its ViewState disabled, then child controls also had their ViewState disabled, even if their EnableViewState was set to true. a) Thus if I understand it correctly, then a child control C having ViewStateMode property set to “Enable” causes C to save its view state, even if parent control has its view state disabled? b) Is there a reason why ViewStateMode property hasn’t/couldn’t be implemented in earlier versions of Asp.Net? thanx

• How can I capture the keystroke that triggers "CellEndEdit" on a DataGridView in C#?

  - by Andy Stampor

  I have a DataGridView that is set to EditOnF2. I do some special processing of data in the CellEndEdit eventhandler that sets the value of the cell. I still want the functionality of the EditOnKeystrokeOrF2 of reverting to the original value when the Esc key is pressed. Unfortunately, at the CellEndEdit eventhandler, I don't see a way to tell what caused the CellEndEdit event to be fired. I only want to change the value of the cell if the Esc key is not pressed. How can I tell if it was or not? Edit: It is worth noting that the KeyDown event does not get fired when the cell is being edited, nor for the final ending keystroke. Edit2: I have tried the KeyPreview suggestion, but the form still does not capture the Escape key being pressed. Edit3: I've been experimenting with trying to get this working. I originally posted some of the following as a separate post, but feel it might be more relevant to include it here. I have a cell in a DataGridView that is now set to EditProgrammatically. To capture the keystroke that starts an edit, I am setting the cell.Value equal to the keystroke. However, this ruins the "Escape" functionality of the cell - when you press escape, instead of reverting to the original value, it reverts to the keystroke that I programmatically inserted into the cell. I believe that if I could set the "EditedFormattedValue" on a cell, this would be where I want to put my keystroke value, however this appears to be read only. How can I accomplish what I am attempting? An example to clarify: If the cell has a value of "54.3" in it, and I press the "9" key, it begins editing the cell and places a "9" there. If I hit Escape, instead of reverting to "54.3" it reverts to "9". What I want is for it to return to its original value of "54.3". So, I am trying to tackle this issue from both the beginning and the end. I think the real problem is that I am overwriting the original value and have no way to determine if I should revert it or not. Edit4: It looks like CellValidating might be worth using, but I am seeing strange behavior when I experiment with it. In a new project, I create the DataGridView and register for the various events and see that CellValidating is fired before the CellEndEdit. However, in my project where I am trying to get this to work, CellEndEdit is firing BEFORE CellValidating. Any ideas on what the difference might be?

• I am unable to find login page for phpmyadmin

  - by Awan

  I was using phpmyadmin(in Wamp) without a password for root. I thought to set a password for root and goto Privileges page and set a password for root. Now whenever I go to localhost/phpmyadmin page it gives me the following error. MySQL said: Documentation #1045 - Access denied for user 'root'@'localhost' (using password: NO) phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server. I don't know that what is the problem. It is not showing me a login type page to enter a username and password. Any idea that what is the problem ? Thanks

The only thing it does is receives incoming calls and executes a Perl script. No outgoing calls, no incoming calls to an actual phone, no phones registered with Asterisk. It seems like there should be an easy way to block all unauthorized registration attempts, but I have struggled with this for a long time. It seems like there should be a more effective way to prevent these attempts from even getting far enough to reach my Asterisk logs. Some setting I could turn on/off that doesn't allow registration attempts at all or something. Is there any way to do this? Also, am I correct in assuming that the "Registration from ..." messages are likely people attempting to get access to my Asterisk server (probably to make calls on my account)? And what's the difference between those messages and the "Sending fake auth rejection ..." messages? Further detail: I know that the "Registration from ..." lines are intruders attempting to get access to my Asterisk server. With Fail2Ban set up, these IPs are banned after 5 attempts (for some reason, one got 6 attempts, but w/e). But I have no idea what the "Sending fake auth rejection ..." messages mean or how to stop these potential intrusion attempts. As far as I can tell, they have never been successful (haven't seen any weird charges on my bills or anything). Here's what I have done: Set up hardware firewall rules as shown below. Here, xx.xx.xx.xx is the IP address of the server, yy.yy.yy.yy is the IP address of our facility, and aa.aa.aa.aa, bb.bb.bb.bb, and cc.cc.cc.cc are the IP addresses that our VoIP provider uses.

• On Edit Grid view Multiple row edit validation

  - by franics

  I am using a telerik radgrid so there are around 5 columns each column edittemplate contains a control along with a required field validator and also a property called AllowMultiRowEdit is set to true so i am able to multiple rows in edit mode. If any of the values are cleared the for multiple rows I want only those to be validated on update of that particular row. So i implemented the Grids item data bound event find each and every validator along with the update button and set a unique validation group. The above implementation most times but fails at some time. Is there any other way of going about this ?

• Flip clock showing time issue (animations invovled)

  - by Hwang

  I'm creating a flip clock (clock where you always see in airport), but I can't seems to get the time to show at the correct timing. After the flip, then will see the number changing. But I want it to change before it flips. Currently I'm not sure whether is the animation problem, or isit I have to do something else on the script. I've uploaded the FLA so that you could have a look on how I set up the flipping animation. http://www.mediafire.com/?nzmymjgtntz Below is the AS3 code: package { import flash.display.MovieClip; import flash.events.TimerEvent; import flash.utils.Timer; public class flipClock extends MovieClip { private var clock:clockMC=new clockMC(); //seconds private var secTop1=clock.second.top1.digit; private var secTop2=clock.second.top2.digit; private var secBot1=clock.second.bot1.digit; private var secBot2=clock.second.bot2.digit; private var seconds:Number; private var minutes:Number; private var hours:Number; private var days:Number; public function flipClock():void { decrease(); addChild(clock); } private function decrease():void { var countdownTimer:Timer=new Timer(1000); //Adding an event listener to the timer object countdownTimer.addEventListener(TimerEvent.TIMER,updateTime); //Initializing timer object countdownTimer.start(); } private function updateTime(event:TimerEvent):void { decreasTimerFunction(); updateSecond(); //updateMinute(); } private function updateSecond():void { clock.second.play(); secTop1.text=num2; secTop2.text=num1; if (num1<10) { num1="0"+num1; } if (num2<10) { num2="0"+num2; } if (num1==60) { num1=0; } if (num2==60) { num2=0; } secTop1.text=num1; secTop2.text=num2; //secBot1.text=num1; //secBot2.text=num2; } private function decreasTimerFunction():void { //Create a date object for Christmas Morning var endTime:Date=new Date(2010,4,26,0,0,0,0); //Current date object var now:Date=new Date(); // Set the difference between the two date and times in milliseconds var timeDiff:Number=endTime.getTime()-now.getTime(); seconds=Math.floor(timeDiff/1000); minutes=Math.floor(seconds/60); hours=Math.floor(minutes/60); days=Math.floor(hours/24); // Set the remainder of the division vars above hours%=24; minutes%=60; seconds%=60; } } }

• Anyone succeeded at injecting Interfaces into Entity Framework 4 Entities, using T4?

  - by Ciel

  Hello: POCO sort of leaves me wanting: (how can I say I use DI/IoC, if the Repository is not the only place that is creating the entities?)...hence my desire to lock it down, get rid of the temptation of newing up POCOs or EntityObjects anywhere in the code, and just allowing entity interfaces above the Repository/Factory layer. For a second there, I nearly thought I had it...was editing EF4's T4 in order to inject in an Interface def. Was going swimmingly, compiled and worked, until I got to the Associations... I wrapped them with a ICollection, and renamed the underlying original collection with a prefix of Wrapped.

• How to automate configurating DotNetNuke settings for several environments?

  - by Joosh21

  Are there any recommended methods for automating configuring DotnetNuke settings? We will have several instances of our DNN application (prod, beta, qa, dev, local, etc) and need to be able to configure them all the same and be able to make updates to them all with our future releases. The settings currently needed to be configured include Host Settings, Portal Settings and User Profile Definitions. Here are some approaches I have come up with so far: 1) Create a Configuration module and use SQL scripts for all the settings? Is it generally safe to manipulate the DNN tables directly? Often it is recommended to use APIs with many frameworks. 2) Create a Configuration module and implement IUpgradeable.UpgradeModule and programatically set the settings? 3) Create a PortalTemplate from a portal with the settings all set. I believe this will only work for creating new portals. I will not be able to update existing portals.

• Stack trace in website project, when debug = false

  - by chandmk

  We have a website project. We are logging unhanded exceptions via a appdomain level exception handler. When we set debug= true in web.config, the exception log is showing the offending line numbers in the stack trace. But when we set debug = false, in web.config, log is not displaying the line numbers. We are not in a position to convert the website project in to webapplication project type at this time. Its legacy application and almost all the code is in aspx pages. We also need to leave the project in 'updatable' mode. i.e. We can't user pre-compile option. We are generating pdb files. Is there anyway to tell this kind of website projects to generate the pdb files, and show the line numbers in the stack trace?

• In C#, can I hide/modify accessors in subclasses?

  - by Diego

  I'm not even sure what this principle is called or how to search for it, so I sincerely apologize if it has been brought up before, but the best way to do it is with an example. class Properties { public string Name { get; set; } } class MyClass { class SubProperties: Properties { public override Name { get { return GetActualName(); } set { _value = SetActualName(value); } } } public SubProperties ClassProperties; private GetActualName() { ClassProperties.Name = "name"; } private SetActualName(string s) { ClassProperties.Name = SomeOtherFunction(s); } } The idea is to have any object that instantiates MyClass have a fully accessible property ClassProperties. To that object, it would look exactly like a Properties object, but behind the scenes, MyClass is actually computing and modifying the results of the fields. This method of declaration is obviously wrong since I can't access GetActualName() and SetActualName() from within the SubProperties definition. How would I achieve something like this?

• jqueryForm and empty uploads

  - by Aiden Bell

  Hi All, Been scratching my head for too long on this: Using jquery.form, (http://malsup.com/jquery/form) with PHP ... my $_FILES['someimage'] gets set but the error number is always UPLOAD_ERR_NO_FILE, size is also 0. The JavaScript: $('form input[type=file]').change(function(){ $(this).clone().appendTo('#imgform'); $('#imgform').ajaxForm(); $('#imgform').ajaxSubmit( { type:'POST' } ); }); Which appends to: <form id="imgform" method="POST" action="/api/images.php" enctype="multipart/form-data"></form> From another form which has bog-standard file inputs. PHP logs are clean, but var_dumping $_FILES always shows that the index is set to the name of the form element ... but no data. Thanks guys! (Sorry, I know jQuery-like questions are too frequent round these parts).

• J2ME TextField Exception

  - by Bob

  When I instantiate a textField, I have a number in it that I want to be the default text. The problem is, I can't seem to be able to place that value into the textfield without getting an error. The strange thing about it is that the same TextField is what I use to set the value of the variable containing the number. TextField myTF = new TextField("Number", value, 10, TextField.NUMERIC); When I run this code, I receive an exception stating that value doesn't match the constraints of TextField.NUMERIC. However, when I check the vale of the value of the variable, I get the following output: value = 1234567890 value.length() = 10 The value is set by the same TextField, saved to the phone that I am working on, and when loaded from the phone's settings, throws an exception.

• How to use xcode compiler warnings to determine minimum IOS deployment target

  - by Martin Bayly

  I'm building an iOS app using Xcode 3.2.5 with the Base SDK set to iOS 4.2 I know I've used some api's from 4.0 and 4.1 but not sure about whether I actually require 4.2. According to the iOS Development Guide, "Xcode displays build warnings when it detects that your application is using a feature that’s not available in the target OS release". So I was hoping to use the compiler warnings to derive my minimum OS requirement. However, even when I set my iOS Deployment Target to iOS 3.0, I still don't get any compiler warnings. I must be doing something wrong, but not sure what? Can anyone confirm that they get compiler warnings when the iOS deployment target is less than the base SDK and the code uses base SDK functions? Or do the compiler warnings only show if you link a framework that didn't exist in the iOS deployment target version?

• applicationShouldTerminateAfterLastWindowClosed: does not seem to work when the red x is used to clo

  - by Michael Minerva

  I have a small OSX Cocoa app that just bring up an IKPicutreTaker and saves the picture to a file if one is set. I use applicationShouldTerminateAfterLastWindowClosed: to close the application when the pictureTaker is closed. This all works fine when I either set(this is done when you have picked the picture you want) or when you hit cancel, but when I click on the red arrow in the top left of the windows, the application does not quit when the window is closed this way. Is this intended functionality or am I doing something wrong (not setting some flag?). Also, is there some way to disable this button?

• Whats the best way to stop this app crash when buttons rapidly pressed iphone obj-c

  - by dubbeat

  Hi, I'm not entirely sure why this crash is happening and I'd like to get advice on the best way to deal with it. My app has 3 buttons. Each button requests a different XML file from a server which is used to populate a table view. If I rapidly press the buttons in sequence , button 1 button 2 button3 button 1 button 2 button3 button 1 button 2 button3 the application quits. What could be causing this. Would id be in the NSURLRequest side of things or the table view population side? How would you suggest I stop this behaviour? I was going to just set a boolean "isRequesting" to true when a button is pressed and set it to false when the table view is finished populating. If any button is pressed while isRequesting is True they do nothing. Does that sound wise or is there a better way? Thanks, dub

• Is Win32_PerfFormattedData_PerfDisk_PhysicalDisk missing from WMI in Vista?

  - by Martin

  From what I understand, the following script should work in Windows XP and higher, but it doesn't work for me in Vista Business 32-bit Service Pack 2. Thus far I have been very unsuccessful googling for information about this performance class. strComputer = "." Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2") Set colApps = objWMIService.ExecQuery("Select * from Win32_PerfFormattedData_PerfDisk_PhysicalDisk") For Each objApp in colApps Wscript.Echo objApp.Caption Next Does this WMI class simply not exist in Vista? If it is just me, is there a way to fix WMI? I have already tried running winmgmt /resetrepository and winmgmt /resyncperf and neither helps.

• MySQL Insert Statement Queue

  - by Justin

  We are building an ajax application in which a users input is submitted for processing to a php script. We are currently writing every request to a log file for tracking. I would like to move this tracking into a database table but I do not want to run a insert statement after request. What I would like to do is set up a 'queue' of transactions (inserts and updates) that need to be processed on the MySQL database. I would then set up a cron job or process to check and process the transactions in the queue. Is there something out there that we could build upon or do we have to just write to plain ol' text log files and process them?

• How doe we name test methods where we are checking for more than one condition?

  - by Sandbox

  I follow the technique specified in Roy Osherove's The Art Of Unit Testing book while naming test methods - MethodName_Scenario_Expectation. It suits perfectly well for my 'unit' tests. But,for tests that I write in 'controller' or 'coordinator' class, there isn't necessarily a method which I want to test. For these tests, I generate multiple conditions which make up one scenario and then I verify the expectation. For example, I may set some properties on different instances, generate an event and then verify that my expectations from controller/coordinator is being met. Now, my controller handles events using a private event handler. Here my scenario is that, I set some properties, say 3 condition1,condition2 and condition3 Also, my scenario includes an event is raised I don't have a method name as my event handler is private. How do I name such a test method?

• Equivalent of describeType for Flex Component EVENTS

  - by Joshua

  Using "introspection" In Flex I can say: var classInfo:XML=describeType(SomeObject); Which will list for me the Accessors, Methods And Variables. (http://livedocs.adobe.com/flex/3/html/help.html?content=usingas_8.html) But what is the equivalent to programmatically inspect all of an object's possible EVENTS? (NOT JUST the events for which event listeners have been set, but to somehow step through a list of all VALID EVENTS for which event listeners may POTENTIALLY be set -- I realize that such lists are readily available online, and that's great for cases when I know the object's type at design type, but I require some way to inspect any given displayobject programmatically at runtime, and determine what events, if any, are or may be associated with it.)

• InvalidOperationException When XML Serializing Inherited Class

  - by Nick

  I am having an issue serializing a c# class to an XML file that has a base class... here is a simple example: namespace Domain { [Serializable] public class ClassA { public virtual int MyProperty { get; set; } } } namespace Derived { public class ClassA : Domain.ClassA { public override int MyProperty { get { return 1; } set { /* Do Nothing */ } } } } When I attempt to serialize an instance of Derived.ClassA, I receive the following exception: InvalidOperationException(Types 'Domain.ClassA' and 'Derived.ClassA' both use the XML type name 'ClassA', from the namespace ". Use XML attributes to specify a unique XML name and/or namespace for the type.) The problem is that I want to create a single base class that simply defines the structure of the XML file, and then allow anyone else to derive from that class to insert business rules, but that the formatting will come through from the base. Is this possible, and if so, how do I attribute the base class to allow this?

• How to use ctrl-i for an emacs shortcut without breaking tabs

  - by mksuth

  I want to redefine the emacs keyboard shortcut control-i to be "MOVE CURSOR UP" To do this, I added the following line to my .emacs file: (global-set-key (kbd "C-i") 'previous-line) What I then discovered is that the tab key, by default, does whatever is bound to control-i, which is obviously not what I want. So, to restore normal tab behavior, I added this to my .emacs file (global-set-key (kbd "<tab>") 'indent-for-tab-command) This mostly works. BUT, tab no longer works for auto-completing commands in the mini buffer. How can I fix that? Or is there a better way of going about this? Thanks.

• IIS7 + ASP.NET MVC Client Caching Headers Not Working

  - by Tobin Harris

  Hey folks I've deployed an ASP.NET MVC app on IIS7 and Windows Server 2008. I've read posts on here, and around the web, but can't get the darn client-side caching to work. I'm trying to cache everything in the /Content folder. So far I've select that folder in IIS manager, and set the appropriate HTTP Response Headers (under Common Headers). I've also checked the web.config file in the /Content folder and the values there are being set. All resources in /Content come back with this (from FireBug): Cache-Control no-cache, no-store, must-revalidate Pragma no-cache Content-Type image/png Expires -1 Last-Modified Sun, 11 Oct 2009 19:01:40 GMT Accept-Ranges bytes Etag "f318d643a54aca1:0" Server Microsoft-IIS/7.0 X-Powered-By ASP.NET Date Sun, 11 Oct 2009 20:40:01 GMT Content-Length 620 Note the Cache-Control and Expires values for this static image being requested. The site is currently compiled in Debug (this will change), but surely that wouldn't make a difference? Obviously I'm overlooking something, any ideas would be appreciated. Thanks
