  • WPF: Apply ScrollBar Style to ListBox Template - Error object cannot be added to border

    - by TheMar
    Hi, I thought this may be straightforward question but did not find any definitive answer while searching net or SO. I have created scrollbar style (using standard scroll bard template - Blend 2) I am not sure how to apply this style "MyScrollStyle" to a ListBox Template . I saw on ListBox template they have Scroll Viewer -- which should contain the scrollbar Assuming it is something simple as ---Content Added--- After going through lot of xaml in template edit I kind of understood how to apply style. I am trying to add the scroll view style set in this example -http://blog.xamltemplates.net/wp-content/uploads/2008/12/scrollviewer.zip, to my list view template but it gives error -- System.Windows.Markup.XamlParseException was unhandled Message="'ScrollViewer' object cannot be added to 'Border'. Exception has been thrown by the target of an invocation. Error at object 'System.Windows.Controls.ScrollViewer' in markup file 'MenuModule, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null;component/resources/Resources.xaml' Line 19 Position 26." Source="PresentationFramework" LineNumber=19 LinePosition=26 NameContext="1_T" Any help is appreciated Thank you, The Mar

  • Custom DataAnnotation attribute with datastore access in ASP.NET MVC 2

    - by mare
    I have my application designed with Repository pattern implemented and my code prepared for optional dependency injection in future, if we need to support another datastore. I want to create a custom validation attribute for my content objects. This attribute should perform some kind of datastore lookup. For instance, I need my content to have unique slugs. To check if a Slug already exist, I want to use custom DataAnnotation attribute in my Base content object (instead of manually checking if a slug exists each time in my controller's Insert actions). Attribute logic would do the validation. So far I have come up with this: public class UniqueSlugAttribute : ValidationAttribute { private readonly IContentRepository _repository; public UniqueSlugAttribute(ContentType contentType) { _repository = new XmlContentRepository(contentType); } public override bool IsValid(object value) { if (string.IsNullOrWhiteSpace(value.ToString())) { return false; } string slug = value.ToString(); if(_repository.IsUniqueSlug(slug)) return true; return false; } } part of my Base content class: ... [DataMember] public ContentType ContentType1 { get; set; } [DataMember] [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = "Validation_SlugIsBlank")] [UniqueSlug(ContentType1)] public string Slug { get { return _slug; } set { if (!string.IsNullOrEmpty(value)) _slug = Utility.RemoveIllegalCharacters(value); } } ... There's an error in line [UniqueSlug(ContentType1)] saying: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type." Let me explain that I need to provide the ContentType1 parameter to the Constructor of UniqueSlug class because I use it in my data provider. It is actually the same error that appears if you try do to this on the built-in Required attribute: [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = Resources.Localize.SlugRequired] It does not allow us to set it to dynamic content. In the first case ContentType1 gets known at runtime, in the second case the Resources.Localize.SlugRequired also gets known at runtime (because the Culture settings are assigned at runtime). This is really annoying and makes so many things and implementation scenarios impossible. So, my first question is, how to get rid of this error? The second question I have, is whether you think that I should redesign my validation code in any way?

  • heroku corrupted object, git fsck fails in rails

    - by Ryan Max
    Hello. I am trying to push an app to heroku and I am getting the error detailed here. So I am trying to determine the corrupt objects using git fsck -full but it isn't returning anything. Nothing happens: Ryan@Ryan-PC ~ $ git fsck --full Ryan@Ryan-PC But I get the object error when I try to push the object to heroku. Is there anyway I can go about repairing the corrupt repository, or can I just delete it and start over? How do I go about doing this?

  • Using 32bit COM object from C# or VBS on Vista 64bit and getting error 80004005

    - by alexandroid
    I need some mind reading here, since I am trying to do what I do not completely understand. There is a 32-bit application (electronic trading application called CQG) which provides a COM API for external access. I have sample programs and scripts which access this API from Excel, .NET (C++, VB and C#) and shell VBScript. I have these .NET applications as source code and as compiled executables (32-bit, compiled on Windows XP). Now I have Windows Vista Home 64-bit which makes my head to spin. Excel examples work just fine (in Excel 2003). Compiled .NET sample executables work as well. But when I am trying to run .NET C# sample converted to and compiled by Visual Studio C# Expression, or run the VBScript script, I am getting error 80004005 when trying to create an object. Initially the .NET application also gave me 80040154 but then I figured how to make it produce 32-bit code and not 64-bit, so now the errors in C# and VBScript applications are the same. That's all the progress I got for now. And yes, I tried running 32-bit versions of cscript.exe/WScript from SysWOW64 folder on my VBS, but still the result is the same (80004005). How to solve this problem? I am almost ready to believe it is practically impossible, but the fact that Excel VBA works and .NET executables compiled on Windows XP run just fine just makes me angry. There should be a way to beat this thing (some secret which probably only Windows Vista developers know)! I will appreciate any help! PS: I believe code samples do not make much sense here, but this is the line of VBScript which fails: Set CEL = WScript.CreateObject("CQG.CQGCEL.4.0", "CEL_") And this is C#: CQGCEL CEL = new CQGCEL(); Update: Forgot to say UAC is off, of course. And I am working from account with administrator priviledges. I also tried watching which registry keys are read using Process Monitor but everything looks OK for GUIDs of this object. I could not recognize some other GUIDs so I am not sure whether they were critical or not. Is there a chance that this COM object uses Internet Explorer and gets the wrong one (like Internet Explorer 7 instead of Internet Explorer 6 engine or something)?

  • Cannot use standard android color attribute in custom color selector

    - by Manish Gupta
    So, android defines the following in themes.xml: <style name="Theme"> ... <item name="colorPressedHighlight">@color/legacy_pressed_highlight</item> </style> and: <style name="Theme.Holo"> ... <item name="colorPressedHighlight">@color/holo_blue_light</item> </style> I want to use this colorPressedHighlight as the background color for my custom Button when it is pressed. So I defined the following in res/color/app_button_background.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_pressed="true" android:drawable="?android:colorPressedHighlight"/> <item android:drawable="@android:color/transparent" /> </selector> Finally, I define my custom ImageButton style: <style name="App_ImageButtonStyle" parent="@android:style/Widget.ImageButton"> <item name="android:gravity">center</item> <item name="android:background">@color/app_button_background</item> </style> I crash on app launch with the following call stack: 06-27 20:24:41.954: E/AndroidRuntime(532): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.StateListDrawable.inflate(StateListDrawable.java:178) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXmlInner(Drawable.java:867) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.graphics.drawable.Drawable.createFromXml(Drawable.java:804) 06-27 20:24:41.954: E/AndroidRuntime(532): at android.content.res.Resources.loadDrawable(Resources.java:1920) I know that directly accessing @color/legacy_pressed_highlight or @color/holo_blue_light instead of accessing them through the colorPressedHighlight fixes the crash but it does not solve the problem. Themes can vary, hence I need to access it through the colorPressedHighlight attribute. PS: I had a similar problem to which I haven't found an answer yet. Can someone please help!

  • Making an svg image object clickable with onclick, avoiding absolute positioning

    - by user256410
    I have tried to change the images on my site from to svg, changing img tags to embed and object tags(standard procedure, i think). But, implementing the onclick function, which previously was contained in the img tag is proving most difficult. I found onclick had no effect when placed inside the object or embed tag. So, I made a div exclusively for the svg, and placed onclick in this div tag. But, no effect unless visitor clicks on the edges/padding of the image. I have read about overlaying a div, but am trying to avoid using absolute positioning, or specifying positions at all. Maybe there's a way to do it without specifying postions? Or maybe theres another way to apply onclick to a svg. Has anyone encountered this problem? Questions and suggestions are welcome.

  • How do you guys handle custom yum repository?

    - by luckytaxi
    I have a bunch of tools (nagios, munin, puppet, etc...) that gets installed on all my servers. I'm in the process of building a local yum repository. I know most folks just dump all the rpms into a single folder (broken down into the correct path) and then run createrepo inside the directory. However, what would happen if you had to update the rpms? I ask because I was going to throw each software into its own folder. Example one, put all packages inside one folder (custom_software) /admin/software/custom_software/5.4/i386 /admin/software/custom_software/5.4/x86_64 /admin/software/custom_software/4.6/i386 /admin/software/custom_software/4.6/x86_64 What I'm thinking of ... /admin/software/custom_software/nagios/5.4/i386 /admin/software/custom_software/nagios/5.4/x86_64 /admin/software/custom_software/nagios/4.6/i386 /admin/software/custom_software/nagios/4.6/x86_64 /admin/software/custom_software/puppet/5.4/i386 /admin/software/custom_software/puppet/5.4/x86_64 /admin/software/custom_software/puppet/4.6/i386 /admin/software/custom_software/puppet/4.6/x86_64 Ths way, if I had to update to the latest version of puppet, I can save manage the files accordingly. I wouldn't know which rpms belong to which software if I threw them into one big folder. Makes sense?

  • How to Deserialize XMLDocument to object in C#?

    - by Deepfreezed
    I have a .Net webserivce that accepts XML in string format. XML String sent into the webserivce can represent any Object in the system. I need to check the first node to figure out what object to deserialize the XML string. For this I will have to load the XML into an XMLDocument (Don't want to use RegEx or string compare). I am wondering if there is a way to Deserialize the XMLDocument/XMLNode rather that deserializing the string to save some performance? Is there going to be any performance benefit serializing the XMLNode rather that the string? Method to Load XMLDocument public void LoadFromString(String s) { m_XmlDoc = new XmlDocument(); m_XmlDoc.LoadXml(s); } Thanks

  • Actionscript/Flex - Is it possible to dynamically extend an object, modify functions, add functions

    - by RR
    I know this question might be frowned upon, but actionscript is a dynamic language similar to javascript and in javascript I can take an object from a library written by someone else and dynamically (at runtime) add/remove/modify functions, properties, prototypes etc. this is kind of like dynamically extending an object to make it work with the library it came with as well as another library. Is something like this possible in flex actionscript? I'm thinking it is only possible with classes that are declared 'dynamic' and definitely not possible with classes declared 'final'. What are your thoughts? Any ideas/tricks?

  • Linux LiveCD (or LiveUSB) with custom xorg.conf

    - by Jakub Narebski
    Is there some Live Linux distribution (on CD, DVD or USB), which allow one to use specific xorg.conf file, i.e. specific X11 configuration? The problem I am trying to solve is to find Linux Live distribution for web browsing which would work well with NEC LCD 22WV monitor. It is supposedly DDCCCI capable, but X.Org X Window System autoconfiguration fails to detect proper modeline, and uses fallback 800x600 screen resolution, instead of preferred screen resolution of 1680x1050.

  • How to use a custom .bashrc file on SSH login

    - by gsingh2011
    I've found that with the new company I'm working with I often have to access linux servers with relatively short lifetimes. On each of these servers I have an account, but whenever a new one is created, I have to go through the hassle of transferring over my .bashrc. It's possible however that in about a months time that server won't be around anymore. I also have to access many other servers for short periods of times (minutes) where it's just not worth it to transfer over my .bashrc but since I'm working on a lot of servers, this adds up to a lot of wasted time. I don't want to change anything on the servers, but I was wondering if there was a way to have a "per-connection" .bashrc, so whenever I would SSH to a server my settings would be used for that session. If this is possible, it would be nice if I could do the same thing with other configuration files, like gitconfig files.

  • D3.js binding an object to data and appending for each key

    - by frshca
    I'm a D3.js newbie and I'm learning how to play around with data. Let's say I have an object with names as keys, and each key has an array of numbers like this: var userdata = { 'John' : [0, 1, 3, 9, 8, 7], 'Harry': [0, 10, 7, 1, 1, 11], 'Steve': [3, 1, 4, 4, 4, 17], 'Adam' : [4, 77, 2, 13, 11, 13] }; For each user, I would like to append an SVG object and then plot the line with the array of values for that user. So here is my assumption of how that would look based on tutorials, but I know it is incorrect. This is to show my limited knowledge and give better understanding of what I'm doing: First I should create the line var line = d3.svg.line().interpolate('basis'); Then I want to bind the data to my body and append an svg element for each key: d3.select('body') .selectAll('svg') .data(userdata) .enter() .append('svg') .append(line) .x(function(d, i) { return i; }) .y(function(d) { return d[i]; }); So am I close??

  • Correct way to load image into UIWebView from NSData object

    - by rustyshelf
    I have downloaded a gif image into an NSData object (I've checked the contents of the NSData object and it's definitely populated). Now I want to load that image into my UIWebView. I've tried the following: [webView loadData:imageData MIMEType:@"image/gif" textEncodingName:nil baseURL:nil]; but I get a blank UIWebView. Loading the image from the same URL directly works fine: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:imageUrl]]; [imageView loadRequest:request]; Do I need to set the textEncodingName to something, or am I doing something else wrong? I want to load the image manually so I can report progress to the user, but it's an animated gif, so when it's done I want to show it in a UIWebView. Edit: Perhaps I need to wrap my image in HTML somehow? Is there a way to do this without having to save it to disk?

  • Deserialization of JSON object by using DataContractJsonSerializer in C#

    - by user2539667
    enter code hereI'm sure this question has been asked over and over again, but for some reason, I still can't manage to get this to work. I want to deserialize a JSON object that contains a single member; a string array: [{"idTercero":"cod_Tercero"}] This is the class that I'm trying to deserialize into: [DataContract] public class rptaOk { [DataMember] public string idTercero { get; set; } public rptaOk() { } public rptaOk(string idTercero) { this.idTercero = idTercero; } } This is the method that I try to deserialize: public T Deserialise<T>(string json) { DataContractJsonSerializer deserializer = new DataContractJsonSerializer(typeof(T)); using (MemoryStream stream = new MemoryStream(Encoding.Unicode.GetBytes(json))) { T result = (T)deserializer.ReadObject(stream); return result; } } And so try to fill the object: rptaOk deserializedRpta = deserializarOk(rpta); But for some reason, this returns "" MessageBox.Show(deserializedRpta.idTercero);

  • Custom PHPINIDir setting in VirtualHost affecting other VirtualHosts

    - by Radio
    One of the clients requested a personal php.ini configuration for his website, so I have set his VirtualHost as follows: <VirtualHost *:80> DocumentRoot "/home/alex/www.domain.tld" ServerName www.domain.tld AssignUserID alex alex PHPINIDir /home/alex/php.ini </VirtualHost> The client created php.ini file under /home/alex/ which contains only this setting: session.save_path = "/home/alex/.php_sessions/" Afterall he started to complaint that he sees all other session files generated by other clients' websites. After doing some basic troubleshooting, I realized, that his php.ini settings are affecting all websites specified in the httpd-vhosts.conf. Question is why? Since PHPINIDir is only specified inside one specific VirtualHost?
