• ReportViewer height issue. Hiding scrollbars.

  - by Tommy Jakobsen

  Hi, I'm using MSSQL 2005 Reporting Services and in this case I need to display some reports on an ASP.NET page using the ReportViewer control (I guess thats the only way, right?). The problem is that I can't get the property SizeToReportContent to work. When displaying the report, I get a vertical scrollbar because the report is too large. It looks like an iframe window. Searching on google it seems to be a bug. It can be fixed by setting AsyncRendering to false but I don't want that. I need another solution. I was wondering if it's possible to set the height on the report element using JavaScript after the report has been loaded? Or do you know of another solution? This is really annoying. Thanks in advance.

• Deselecting a form input and waiting for a function before submitting

  - by blcArmadillo

  I have a form with an input field where a user enters a unique identifier. I then have some jQuery code that upon the user moving away from the input field (blur) goes out and fetches details about the part and populates some fields on the page. The problem is if the user clicks the submit button before moving out of the input field the jQuery code never has a chance to load in the data and populate the necessary fields. Whats the best way to go about doing this? I thought about maybe setting the focus to body and then having an infinite loop that keeps checking the page until all fields that should be filled in have been filled in but I feel like some sort of event based solution would be better than unpredictable infinite loops. Any ideas?

• Ant ignores attempt to override the LANG environment variable

  - by Steen

  We need to test a java build with the languages set to different values. I can manually (i.e. via export LANG=en_DK.UTF-8 and export LANG=en_DK) test that the unit tests run with the ant build script behaves differently, but I need to set the environment variable from ant. I have tried setting it using these methods (with the shell $LANG set to en_DK.UTF-8): using -D on the command line: ant -DLANG=en_DK using a build.properties file with the line LANG=en_DK in it using the following statements in the build.xml file (sorry for the formatting, I can't get SO to display it otherwise): : <property environment="ANTENV"/> <property name="ANTENV.LANG" value="en_DK"/> Using any of the three possibilities, and when run with -debug, ant reports that: Override ignored for property "LANG" What can I do to set the LANG environment variable from within ant?

• Ad-Hoc mode and Cell (how does it work)?

  - by Ori Cohen

  hello, I am setting up a wireless Ad-Hoc network manually in linux using iwconfig and ifconfig. I have gotten everything working, and I think I understand it all except access point. The part that confused me is this: If I have essid='some_id', channel=11, Mode=Ad-Hoc and appropriate routing/ip on both laptops, why do I need to make sure the Cell is the same? I was under the impression that Ad-Hoc worked independently of the access point. I can easily get around this, I just use iwconfig wlan0 ap 00:00:00:00:00:01 Why is this necessary? I've been unable to find a good tutorial on this. If anyone can clear this up I'd appreciate it. Thanks

• Handling Character Encoding in URI on Tomcat

  - by ZZ Coder

  On the web site I am trying to help with, user can type in an URL in the browser, like following Chinese characters, http://localhost:8080?a=?? On server, we get GET /a=%E6%B5%8B%E8%AF%95 HTTP/1.1 As you can see, it's UTF-8 encoded, then URL encoded. We can handle this correctly by setting encoding to UTF-8 in Tomcat. However, sometimes we get Latin1 encoding on certain browsers, http://localhost:8080?a=ß turns into GET /a=%DF HTTP/1.1 Is there anyway to handle this correctly in Tomcat? Looks like the server has to do some intelligent guessing. We don't expect to handle the Latin1 correctly 100% but anything is better than what we are doing now by assuming everything is UTF-8. The server is Tomcat 5.5. The supported browsers are IE 6+, Firefox 2+ and Safari on iPhone.

• Autoplay an Audio File on Mobile Safari

  - by phantomdata

  Hey guys, I've got a little system dashboard web app that I've written, replete with alarm notifications. I've had it working for quite some time on mobile safari, but recently wanted to add audio to the alarm notifications to allow me to easily know when there are alarms and I'm not looking directly at the display. The alarm notifications are populated through a (relatively) constantly polling ajax request that pulls in and displays an alarm banner if alarms are present. I wanted to add an auto-playing 'alarm' sound as well, but no dice for Safari Mobile. I've tried using HTML5 and embedded objects with no avail. The Apple documentation does state that you can't auto-play an audio file and it must be activated through user action to conserve bandwidth. Has anyone found a way around this in a WLAN setting?

• How does load balancing work with multiple server with multiple DBs

  - by Matt

  I guess what im looking for is a description on how this all works together. I'm used to setting up one server with maybe another server to handel the DB. My question is how does the load balancer work where do all the script(php,python) files go? If i make a change to one i have to rsync them to all the server that the balancer refers to? Also does each server need client side DB's installed so they can reference the DB's that are on other servers? If there is a site that explains all this i would be happy to read it.

• Pygame program that can get keyboard input with caps

  - by None

  I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I relize this is because the program ignores shift input and instead writes the text if it's number is under 128. I have thought of setting a variable when shift is pressed then capitalizing if it was true, but string capitalization only woks on letters, not things like numbers or semicolons. Is there maybe a number I can add to the ascii number typed to modify it if shift is pressed, or something else?

• Why won't Silverlight handle the conversion of my custom float property

  - by Jeff Weber

  In a Silverlight 4 project I have a class that extends Canvas: public class AppendageCanvas : Canvas { public float Friction { get; set; } public float Restitution { get; set; } public float Density { get; set; } } I use this canvas in Blend by dragging it onto another control and setting the custom properties: When I run the app, I get the following error when InitializeComponent is called on the control containing my custom canvas: I'm not sure why Silverlight isn't able to convert this property from it's string representation in Xaml, to the float that it is. Anyone have any ideas?

• WCF Windows service permissions problem

  - by Elad

  I have created a WCF service and hosted it using Windows Services host. To install the project I created an installation project (as described here). In the tutorial, it says to define in the ProjectInstaller.cs the serviceProcessInstaller1 Account property to be Network Service. When using this setting the service did not started on the server. When I tried to start the process manually, it immediately return to stopped state. After when I changed the Account to LocalSystem the service works properly. My questions are: Any ideas why it won't work with Network Service account? What are the security implications of using a server with LocalSystem account? This server is used locally in the intranet as a reporting server for other servers.

• How do you change the style of cell in a JQuery.DataTable?

  - by Sephrial

  Hello fellow coders, I have a question about setting the style attributes for a data cell in the jQuery.DataTable. I was able to set the width for each column when initializing the dataTable using the following: oTable = $('#example').dataTable( { "aoColumns" : [ { sWidth: '40%' }, { sWidth: '60%' } ] } ); However, now I want to change the alignment for the second column like so: style="text-align: right;". I am adding rows dynamically: /* Global var for counter */ var giCount = 2; function fnClickAddRow() { oTable.fnAddData( [ 'col_1', 'col_2' ] ); giCount++; } Can you tell me how I can select the second cell of the added row after it's inserted? OR can you tell me how to set the style of the row before/during insertion? Any help would be greatly appreciated!

• Implementing Read Only view in Winform App

  - by Refracted Paladin

  I have an in house winform app for viewing, editing, and inserting member data. There are about 40 sepertate form pages that they use to manipulate different portions of the data. My question is this; What is the best way of implementing a read only view for a form page? My thoughts were to cycle through the controls setting Enabled = False or leave them be but not allow any data changes(no Save Button etc) unless it is "unlocked". I am curious how others handle this with WinForm apps?

• Ruby gems gone after after jruby install

  - by James

  Today I installed jruby by downloading it, extracting it to /home/james/jruby-1.4.0 and adding the following line to .bashrc export JRUBY_HOME=/home/james/jruby-1.4.0 export PATH=$JRUBY_HOME/bin:$PATH And then I installed some jruby gems via jruby -S gem install ... Jruby works fine, but this seemed to have cause two problems: 1) When I try to run a ruby (not jruby) on rails migration, I see: Missing the Rails gem. Please `gem install -v= rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed. 2) when I do gem list --local, I only see the gems that I've installed for jruby. Launching web applications via ruby script/server succeeds without any warnings. Please help.

• Program skips code after trying to parse XML in VB.NET

  - by Bead

  I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break. I tried catching exception but none are occurring, so I'm not sure what the problem is. Here is my code: Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream()) Dim xDoc As XmlDocument = New XmlDocument() xDoc.LoadXml(reader.ReadToEnd()) Dim omfg As String = xDoc.ChildNodes().Item(0).InnerText() Dim name As XmlNodeList = xDoc.GetElementsByTagName("div") Dim jj As Integer = name.Count For i As Integer = 0 To name.Count - 1 MessageBox.Show(name.Item(i).InnerText) Next i Anything after the "xDoc.LoadXml(reader.ReadToEnd())" doesn't execute.. Any ideas on this? My XML does have some whitespace at the beginning, I don't know if that is causing the problem...

• ASP.NET Canceling the Default Submit Button

  - by Ryan Smith

  I have an ASP.NET application where there's a few ASP.NET buttons and several plain HTML buttons. Anytime there's a textbox where a user hits enter, the ASP.NET button trys to submit the form. I know I can change the defaultButton, but I don't want there to be any default button. I just want it so when the user presses enter it doesn't do anything. I've tried setting defaultButton to blank, but that doesn't seem to work and I can't seem to find the answer anywhere on the web. What's the code to make this happen? Thanks.

• best practice to obtain time zone for iPhone vs iPod Touch

  - by johnbdh

  I am creating an app that requires the users current time zone. If the device being used is an iPhone and the user has their Time Zone set to automatically change, I think I can be fairly confident that localTimeZone or systemTimezone will give me the correct time zone for the user's location. If on the other hand the device is an iPod Touch, the time zone returned by localTimeZone and systemTimeZone appears to always be whatever time zone is set in the Date & Time settings, regardless of the user's actual location. I tried using location services but, while the lat/long is being provided properly, the time zone offset in the timesStamp I am getting is always the same as whatever the user has set for their time zone setting. Any suggestions? John

• Render view as string then redirect.

  - by JohnRudolfLewis

  In my ASP.NET MVC application, I would like my controller action to render a view to a string, send an email using that string as the body, then do a redirect. I've found several articles here on SO and elsewhere on how to render the view to a string. That part was easy. But when I attempt to perform the redirect, I get an HttpException: Cannot redirect after HTTP headers have been sent. I've tried setting Response.Buffer and Response.BufferOutput to true, I've tried Response.Clear, nothing seems to work. Is it possible to render a view to a string, then do a redirect?

• Browser caching issue on a https site pressing f5

  - by sushil bharwani

  i am working on a website where i have content entry form. This form contains a tiny mce control. The control is composed of some 40-50 files. The testing reported that the entry form loads slow and evertime shows up 50 files loading to completely load the page. Is there a way i can decrease this time. I have taken help of browser caching by setting the expires header of static content to very far date. When i access the form through its link second or later times it loads fast without saying 40 files remaining. but when i do f5 it reloads the entire page. I m confused as to how is f5 different from clicking on the link. Just to add my url is https.Any suggestion to increase the performance of this form will be great.

• Post login execution

  - by Javi

  Hello, I need to do some processing only after the user has successfully logged in the system. I have thought that I can do a RESTful method and setting it as the default-target-url so when the login is successful it goes to this url and then I can redirect to the real index of my web application. <form-login login-page='/login.htm' default-target-url='/home.htm' always-use-default-target='true' /> The problem is that this processing can be executed by calling its URL so it could be executed by any user at any time. I want to make sure it is only executed after login. Is there any way to do this? Thank you very much.

• How to specify a font from javascript?

  - by Steven Lu

  I am trying to customize a view-src bookmarklet for iPad. This one is looking pretty good so far. But I want to make it just a little more readable: The Courier (New) font is a bit ugly even (especially?) on the retina display and I'd prefer any one of DejaVu Sans Mono, Monaco, Lucida Console, Bitstream Vera Sans Mono. I tried to modify the bookmarklet script by adding: pre.style.fontFamily = '"DejaVu Sans Mono", "Lucida Console", Monaco;'; It's not doing the trick. Perhaps prettyprint cancels out my fontFamily setting when it loads. Maybe I can set it at the end of the script somehow...
