• Display Ajax Loader while page rendering

  - by Dean

  This is probably a simple question but how can I best use an AJAX loader in ASP.NET to provide a loading dialog whilst the page is being built? I currently have an UpdatePanel with an associated UpdateProgressPanel which contains the loading message and gif in a ProgressTemplate. Currently I have a page that onLoad() goes and gets the business entities and then displays them. While it is doing this I would like to display an AJAX loader. Would it be better to have nothing in the page load and have a hidden button that is triggered onLoadComplete or unLoad() which would then wait for the button click method to complete displaying the UpdateProgressPanel?

• touchesMoved QuartzDemo application

  - by BittenApple

  I am modifying the QuartzDemo application to include swipe detection while UIView is active (a PDF page being displayed in it via Quartz). This will not work, the event never gets to the QuartzView.m because it sits under scrollview? touchesBegan works fine and I can use single tap. How can I go about with catching touchesMoved while PDF page is being displayed? I need a simple example with code that does nothing on touchesMoved, I'll build up on that later. Please keep in mind that I still want to use the UIScrollview as it is and show PDF content based on selection in that scrollview.

• How do I trigger specific parts of a storyboard in WPF?

  - by George

  I have several grids in my window. I have created a storyboard that moves them left by x pixels when a button is clicked. I want to make it so that when the button is clicked again those grids move another x pixels, however I'm unable to find out how to do this as it's not a common task on tutorials. I have tried creating a second storyboard to do this, however that won't work as then the grids will be back at their starting positions. One solution might be to create a third set of keyframes after the first two sets, and somehow pause the animation when it gets there, and resumes it again when the button is clicked, however I'm not sure how to pause a storyboard when it reaches a keyframe. This would also make reversing the grids difficult (using this approach http://social.msdn.microsoft.com/forums/en-US/wpf/thread/ac54de71-f750-4940-91a2-231810308727/), as I'd like to make another button make the grids go the other way.

• .NET WebService IPC - Should it be done to minimise some expensive operations?

  - by Kyle

  I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

• Possible relationship between PHP Mailer and Mailer-Daemon

  - by XGreen

  Hi, I am using the PHPMailer Class from a website which sends confirmation of the user ajax upload to my client. This uses the mail.myclient.com SMTP Host. This is the same SMTP Host that my client uses for his outlook to check his emails. This email from the website gets sent without errors although I have received two emails from my client regarding Mail delivery failed: returning message to sender for the same address I have used to send confirmation emails out from. Can these two issues be related? Do I need to provide more info? Thanks a bunch!

• Problem with sys.argv[1] when unittest module is in a script

  - by chrissygormley

  Hello, I have a script that does various things and access paramenters using sys.argv but when the script gets to the unittest part of the code it says there is no module for this. The script that I have is: class MyScript(): def __init__(self): self.value = sys.argv[1] def hello(self): print self.value def suite(self): modules_to_test = ('external_sanity_onvif', 'starttest') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests if __name__ == '__main__': Run = MyScript() Run.hello() log_file = 'log_file.txt' test_file = open(log_file, "w") runner = unittest.TextTestRunner(test_file) unittest.main(defaultTest='Run.suite', testRunner=runner) Say I enter ./script.py Hello in the command line. The error I get is: AttributeError: 'module' object has no attribute 'Hello' If I remove the unittest module it works. Also if I remove the testrunner log and leave it at: unittest.main(defaultTest='Run.suite') This still doesn't work. Can anyone help. Thanks

• How to preload local javascript everytime a new tab or page is opened?

  - by Klerk

  I would like to autoload a local javascript file, everytime a new page/tab is opened in a browser. I tried the bookmarklet approach, but it gets tiresome as the button needs to be pressed everytime a new page/tab is opened. Chrome extensions also seem to work along the same lines (where you have to press an icon to run the js). Googling for javascript and preload seems to return everything except what I am looking for. Is there a browser indepent way of autoloading (no user action required) a local js file? If not, any browser specific info to do this would be appreciated (even if they mean reducing security by turning off required options). Thanks!

• Process a batch of items, return an object to report on status

  - by Naeem Sarfraz

  I'm looking for a pattern (or good practice) for the following scenario: My function List<BatchItemResponse> Process(List<BatchItem> Data) {..} will process a list of data, and return info on where each item in the batch could be processed. struct BatchItemResponse { int BatchItemID; bool Processed; string Description; } Any thoughts? Is what I've proposed as good as it gets?

• How can invoke a shell to make a new environment to run a make inside another make?

  - by WilliamKF

  I would like in my GNUmakefile to have a target rule that invokes a new shell and then with the clean slate of the new shell invokes a new make. What is the syntax to do this? I tried this but it didn't work: .PHONY: setup setup: shell cd myDir; make; cd .. It gets infinite repeat of the following error: make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found [...]

• Return specific HREF attribute using Xpath query

  - by Michael Pasqualone

  Having a major brain freeze, I have the following chunk of code: // Get web address $domQuery = query_HtmlDocument($html, '//a[@class="productLink"]'); foreach($domQuery as $rtn) { $web = $rtn->getAttribute('href'); } Which obviously gets the entire href attribute, however I only want 1 specific attribute within the href. I.e. If the href is: /website/product1234.do?code=1234&version=1.3&somethingelse=blaah I only want to return the variable for "version", so wish to only return "1.3" in my example. What's most efficient way to do this?

• CSS: set font weight depending on fallback font

  - by mikez302

  I am trying to set the font-weight for an element based on the font that gets chosen. For example, I may be trying to do something like this: h1 { font-family: Arial Narrow, Impact, sans-serif; font-weight: ?; } Let's say I want the font-weight to be "bold" if the user has Arial Narrow installed on their system, but "normal" if the browser has to use Impact, and maybe "bold" if the user's system has neither of those fonts. Is this possible? If so, how would I go about doing this?

• Activity should be transparent, but has black background

  - by Uwe Krass

  I followed the instructions of writing a transparent layout. My res/values/style.xml looks like this: <resources> <style name="Theme" parent="android:Theme" /> <style name="Theme.Transparent"> <item name="android:windowBackground">@drawable/transparent_background</item> </style> <drawable name="transparent_background">#00000000</drawable> </resources> The activity snippet looks like this: <activity android:name=".Controlls" android:label="Controlls" android:theme="@style/Theme.Transparent"> When I start this activity from my root activity, the layout gets drawn correctly, but the background stays black.

• Queue remote calls to a Python Twisted perspective broker?

  - by agartland

  The strength of Twisted (for python) is its asynchronous framework (I think). I've written an image processing server that takes requests via Perspective Broker. It works great as long as I feed it less than a couple hundred images at a time. However, sometimes it gets spiked with hundreds of images at virtually the same time. Because it tries to process them all concurrently the server crashes. As a solution I'd like to queue up the remote_calls on the server so that it only processes ~100 images at a time. It seems like this might be something that Twisted already does, but I can't seem to find it. Any ideas on how to start implementing this? A point in the right direction? Thanks!

• [Doing it Wrong] Auto Boxing of primitives

  - by Jonathan

  I can't seem to figure out how to get Objective-c to auto box my primitives. I assumed that i would be able to do the following NSString* foo = @"12.5"; NSNumber* bar; bar = [foo floatValue]; However i find that i have used to the more verbose method of NSString* foo = @"12.5"; NSNumber* bar; bar = [NSNumber numberWithFloat:[foo floatValue]]; Am i doing it wrong or is this as good as it gets?

• Scriptaculous Slider stops working in iFrame

  - by KcYxA

  Hi there, I am stumped! I have a form for leaving reviews that uses a slider from the Scriptaculous library. The form is retrieved through Ajax once a user clicks on a link to leave a review and all works fine. In order to enable ajax-looking file uploading, I'm using an iFrame to submit the review. My problem occurs when the form is returned due to user input errors. The slider stops working! No Javascript errors. The Control.Slider gets initialized, yet it doesn't work. Any ideas on why this could be happening? Thanks!

• Visual Studio 2008 Macro for Building does not block thread

  - by Climber104

  Hello, I am trying to write a macro for Building my application, kicking off an external tool, and ataching the debugger to that external tool. Everything is working except for the building. It builds, but it is not blocking the thread so the external tool gets kicked off before it can finish. Is there a way I can run ExecuteCommand and wait for the thread to finish? Code is below: DTE.ExecuteCommand("ClassViewContextMenus.ClassViewProject.Build") DTE.ExecuteCommand("Tools.ExternalCommand11") Try Dim dbg2 As EnvDTE80.Debugger2 = DTE.Debugger Dim trans As EnvDTE80.Transport = dbg2.Transports.Item("Default") Dim dbgeng(1) As EnvDTE80.Engine dbgeng(0) = trans.Engines.Item("Managed") Dim proc2 As EnvDTE80.Process2 = dbg2.GetProcesses(trans, "MINIPC").Item("_nStep.exe") proc2.Attach2(dbgeng) Catch ex As System.Exception MsgBox(ex.Message) End Try

• Getting the 'external' IP address in Java

  Hi I'm not too sure how to go about getting the external IP address of the machine as a computer outside of a network would see it. My following IPAddress class only gets the local IP address of the machine. Any help would be appreciated. Thanks. public class IPAddress { private InetAddress thisIp; private String thisIpAddress; private void setIpAdd(){ try{ InetAddress thisIp = InetAddress.getLocalHost(); thisIpAddress = thisIp.getHostAddress().toString(); } catch(Exception e){} } protected String getIpAddress(){ setIpAdd(); return thisIpAddress; } }

• Android RelativeLayout spacing

  - by fordays

  Hi, I'm just putting the finishing touches to my Android app. Unfortunately, I dug straight into development without reading the documentation and built my layout with AbsoluteLayout and it turned out to look terrible when I loaded the app on my phone. Now I'm redoing the UI in a RelativeLayout and I want to put empty canvas space in between my ViewGroups in the y-direction. I am currently achieving this by putting random TextView sentences that are of the same color as my View's background in order to make psuedo-empty space. Is there a better way to do this, because right now when I define a specific ViewGroup to be placed below another View, it gets stuck right below the top View. As I was writing this, it dawned upon me that using padding might be the answer.... Any other suggestions?

• how to store passwords in database?

  - by rgksugan

  I use jsp and servlets in my web application. i need to store passwords in the database. I found that hashing will be the best way to do that. I used this code to do it. java.security.MessageDigest d = null; d = java.security.MessageDigest.getInstance("SHA-1"); d.reset(); d.update(pass.getBytes("UTF-8")); byte b[] = d.digest(); String tmp = (new BASE64Encoder()).encode(b); When i tried to print the value of tmp, i get some other value.i guess its the hash value of the password. But when i persist this data to the database the original password gets saved there other than the value in tmp.. What is the problem???

• Getting data from a ListView into an array

  - by Joe

  I have a ListView control on my form set up like this in details mode: What I would like to do, is get all the values of the data cells when the user presses the Delete booking button. So using the above example, my array would be filled with this data: values(0) = "asd" values(1) = "BS1" values(2) = "asd" values(3) = "21/04/2010" values(4) = "2" This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(i).Text i = i + 1 Next End Sub But only values(0) gets filled with the first data cell of the selection (in this case "asd") and the rest of the array entries are blank. I have confirmed this with a breakpoint and checked the array entries myself. I'm REALLY lost on this, and have been trying for about an hour now. Any help would be appreciated, thanks :) Also please note that there can only be one row selection at once. Thanks.
