  • Why an input button created dynamically through a literal tag doesn't work ?

    - by user284523
    I have created button 2 below: <input id="Button1" type="button" value="Stop" onclick="alert('hello world');"/> <input id="Button2" type="button" value="button" OnClik="alert('hello world');"/> using a litteral tag on page load like this: protected void Page_Load(object sender, EventArgs e) { Literal1.Text = "<input id=\"Button2\" type=\"button\" value=\"button\" OnClik=\"alert('hello world');\"/>"; } Incredibly when testing in browser, click on button 1 works, not click on button 2 whereas the codes are the same ! Am I missing something ?

  • GIMP: Slightly wrong color when saving images

    - by chris_l
    When I create a new image, fill it with a single color, and save it as *.png or *.jpeg, it gets a slightly wrong color. When I save it as *.gif, the color is correct. Does this have something to do with a color profile? How can I turn it off? (Gimp 2.6.7 on Mac) BTW, when I use "Digital Color Meter" to check the color in the GIMP window, I also get a wrong value - but that value is again a little bit different.

  • How do I make a simple image-based button with visual states in Silverlight 3?

    - by Jacob
    At my previous company, we created our RIAs using Flex with graphical assets created in Flash. In Flash, you could simply lay out your graphics for different states, i.e. rollover, disabled. Now, I'm working on a Silverlight 3 project. I've been given a bunch of images that need to serve as the graphics for buttons that have a rollover, pressed, and normal state. I cannot figure out how to simply create buttons with different images for different visual states in Visual Studio 2008 or Expression Blend 3. Here's where I am currently. My button is defined like this in the XAML: <Button Style="{StaticResource MyButton}"/> The MyButton style appears as follows: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"/> <VisualState x:Name="Pressed"/> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> I cannot figure out how to assign a different template to different states, nor how to change the image's source based on which state I'm in. How do I do this? Also, if you know of any good documentation that describes how styles work in Silverlight, that would be great. All of the search results I can come up with are frustratingly unhelpful. Edit: I found a way to change the image via storyboards like this: <Style x:Key="MyButton" TargetType="Button"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Image Source="/Assets/Graphics/mybtn_up.png" Width="54" Height="24" x:Name="Image"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="FocusStates"> <VisualState x:Name="Focused"/> <VisualState x:Name="Unfocused"/> </VisualStateGroup> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="Normal"/> <VisualState x:Name="MouseOver"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_over.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard Storyboard.TargetName="Image" Storyboard.TargetProperty="Source"> <ObjectAnimationUsingKeyFrames> <DiscreteObjectKeyFrame KeyTime="0" Value="/Assets/Graphics/mybtn_active.png"/> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> <VisualState x:Name="Disabled"/> </VisualStateGroup> </VisualStateManager.VisualStateGroups> </Image> </ControlTemplate> </Setter.Value> </Setter> </Style> However, this seems like a strange way of doing things to me. Is there a more standard way of accomplishing this?

  • SqlParameter contructor compiler overload choice

    - by Ash
    When creating a SqlParameter (.NET3.5) or OdbcParameter I often use the SqlParameter(string parameterName, Object value) constructor overload to set the value in one statement. When I tried passing a literal 0 as the value paramter I was initially caught by the C# compiler choosing the (string, OdbcType) overload instead of (string, Object). MSDN actually warns about this gotcha in the remarks section, but the explanation confuses me. Why does the C# compiler decide that a literal 0 parameter should be converted to OdbcType rather than Object? The warning also says to use Convert.ToInt32(0) to force the Object overload to be used. It confusingly says that this converts the 0 to an "Object type". But isn't 0 already an "Object type"? The Types of Literal Values section of this page seems to say literals are always typed and so inherit from System.Object. This behavior doesn't seem very intuitive given my current understanding? Is this something to do with Contra-variance or Co-variance maybe?

  • How can I have a serializable struct that wraps it's self as an int32 implicitly? in C#?

    - by firoso
    Long story short, I have a struct (see below) that contains exactly one field: private int value; I've also implemented implicit conversion operators: public static implicit operator int(Outlet val) { return val.value; } public static implicit operator Outlet(int val) { return new Outlet(val); } I've implemented all of the following : IComparable, IComparable<Cart>, IComparable<int>, IConvertible, IEquatable<Cart>, IEquatable<int>, IFormattable I'm at a point where I really have no clue why, but whenever I serialize this object, I get no value. For instance, with XmlSerialization: <Outlet /> Also, I'm not solely concerned about XmlSerialization, I'm concerned about ALL serialization (binary for instance) How can I ensure that this serializes properly? NOTE: I did this because mapping an int,int dictionary seemed rather poorly typed to me when explicit objects with validation behavior were desired.

  • c# Regex on XML string handler

    - by Dan Sewell
    Hi guys. Trying to fiddle around with regex here, my first attempt. Im trying to extract some figures out of content from an XML tag. The content looks like this: www.blahblah.se/maps.aspx?isAlert=true&lat=51.958855252721&lon=-0.517657021473527 I need to extract the lat and long numerical vales out of each link. They will always be the same amount of characters, and the lon may or may not have a "-" sign. I thought about doing something like this below: (The string in question is in the "link" tag): var document = XDocument.Load(e.Result); if (document.Root == null) return; var events = from ev in document.Descendants("item1") select new { Title = (ev.Element("title").Value), Latitude = Regex.xxxxxxx(ev.Element("link").Value, @"lat=(?<Lat>[+-]?\d*\.\d*)", String.Empty), Longitude = Convert.ToDouble(ev.Element("link").Value), }; foreach (var ev in events) { do stuff } Many thanks!

If so then there is a possibility that two items having same value in the column. Please confirm.

  • Is this a good or bad way to use constructor chaining? (... to allow for testing).

    - by panamack
    My motivation for chaining my class constructors here is so that I have a default constructor for mainstream use by my application and a second that allows me to inject a mock and a stub. It just seems a bit ugly 'new'-ing things in the ":this(...)" call and counter-intuitive calling a parametrized constructor from a default constructor , I wondered what other people would do here? (FYI - SystemWrapper) using SystemWrapper; public class MyDirectoryWorker{ // SystemWrapper interface allows for stub of sealed .Net class. private IDirectoryInfoWrap dirInf; private FileSystemWatcher watcher; public MyDirectoryWorker() : this( new DirectoryInfoWrap(new DirectoryInfo(MyDirPath)), new FileSystemWatcher()) { } public MyDirectoryWorker(IDirectoryInfoWrap dirInf, FileSystemWatcher watcher) { this.dirInf = dirInf; if(!dirInf.Exists){ dirInf.Create(); } this.watcher = watcher; watcher.Path = dirInf.FullName; watcher.NotifyFilter = NotifyFilters.FileName; watcher.Created += new FileSystemEventHandler(watcher_Created); watcher.Deleted += new FileSystemEventHandler(watcher_Deleted); watcher.Renamed += new RenamedEventHandler(watcher_Renamed); watcher.EnableRaisingEvents = true; } public static string MyDirPath{get{return Settings.Default.MyDefaultDirPath;}} // etc... }

  • SQL: join within same table with different 'where' clause

    - by Pmarcoen
    Ok, so the problem I'm facing is this, I have a table with 3 columns : ID, Key and Value. ID | Key | Value ================ 1 | 1 | ab 1 | 2 | cd 1 | 3 | ef 2 | 1 | gh 2 | 2 | ij 2 | 3 | kl Now I want to select the value of Keys 1 & 3 for all IDs, the return should be like this ID | 1 | 2 ================ 1 | ab | ef 2 | gh | kl So per ID 1 row containing the Values for Keys 1 & 3. I tried using 'join' but since I need to use multiple where clauses I can't figure out how to get this to work ..

  • Why does the data binding in this validation example work?

    - by MartyIX
    I'm wondering how exactly the XAML sample (MSDN sample) works: <Style x:Key="textBoxInError" TargetType="{x:Type TextBox}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/> </Trigger> </Style.Triggers> </Style> Questions: (Validation.Errors)[0].ErrorContent - Is this code somehow checked by WPF? Because Validation.Errors may be an empty collection and in ordinary C# code this code may throw an exception. If this data-binding returns null for valid input - the null value is then casted to empty string (in a text control for example)? The index 0 corresponds to the first error message. How can I return more error messages from Validate method? Thank you for responses!

  • How to increase Java heap space for a tomcat app

    - by Ankur
    There are lots of questions that ask this or a similar question. They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps. I read this page http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html and it says under the Tomcat section Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example, set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value) export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value) setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value) So I replaced the line set CATALINA_OPTS= with set CATALINA_OPTS=-Xms512m -Xmx512m But I still get the error.

  • What information should a SVN/Versioned file commit comment contain?

    - by RenderIn
    I'm curious what kind of content should be in a versioned file commit comment. Should it describe generally what changed (e.g. "The widget screen was changed to display only active widgets") or should it be more specific (e.g. "A new condition was added to the where clause of the fetchWidget query to retrieve only active widgets by default") How atomic should a single commit be? Just the file containing the updated query in a single commit (e.g. "Updated the widget screen to display only active widgets by default"), or should that and several other changes + interface changes to a screen share the same commit with a more general description like ("Updated the widget screen: A) display only active widgets by default B) added button to toggle showing inactive widgets") I see subversion commit comments being used very differently and was wondering what others have had success with. Some comments are as brief as "updated files", while others are many paragraphs long, and others are formatted in a way that they can be queried and associated with some external system such as JIRA. I used to be extremely descriptive of the reason for the change as well as the specific technical changes. Lately I've been scaling back and just giving a general "This is what I changed on this page" kind of comment.

  • jQuery validator and a custom rule that uses AJAX

    - by thatweblook
    Hi, I read your reply regarding the jQuery validator where you outline a method to check a username against a value in a database. Ive tried implementing this method but no matter what is returned from the PHP file I always get the message that the username is already taken. Here is ths custom method... $.validator.addMethod("uniqueUserName", function(value, element) { $.ajax({ type: "POST", url: "php/get_save_status.php", data: "checkUsername="+value, dataType:"html", success: function(msg) { // if the user exists, it returns a string "true" if(msg == "true") return false; // already exists return true; // username is free to use } })}, "Username is Already Taken"); And here is the validate code... username: { required: true, uniqueUserName: true }, Is there a specific way i am supposed to return the message from php.

  • Why the OnWorkflowItemChanged is different between List and document library?

    - by Yongwei Xing
    I am doing a workflow for a document library. I put a OnWorkflowItemChanged, and I want to get the value of the column which is changed. I use the workflowProperties.Item["name"] and use the afterProperties. But when I use the workflowProperties.Item["column name"], I still got the original value. When I use the afterProperties, it's NULL. Then I make another workflow that is the same as above for a list. I can use the workflowProperties.Item["column name"] to get the new value in OnWorkflowItemChanged. Has anyone come across this problem before? Can you give me some help?

  • Is it possible to protect a single element in the appSettings section instead of the entire section?

    - by hambonious
    I would like to protect one key/value pair in my appSettings but not the others using something like I've previously done with the ProtectSection method as seen below. var configurationSection = config.GetSection("appSettings"); configurationSection.SectionInformation.ProtectSection("DataProtectionConfigurationProvider"); Ideally I would like to do something like the following: var configurationElement = config.GetSection("appSettings").GetElement("Protected"); configurationElement.ElementInformation.ProtectElement("DataProtectionConfigurationProvider"); Here is the example appSettings I would be operating on: <configuration> <appSettings> <add key="Unprotected" value="ChangeMeFreely" /> <add key="Protected" value="########"/> </appSettings> </configuration> I've been searching but haven't found a way to do this. Is this possible?

    Is there a technique where I can execute code after a return? I want to return a value then reset the value without introducing a temporary variable. My current code is: function(a){ var b; if(b){ var temp = b; //I want to avoid this step b = false; return temp; }else{ b = a; return false; }; }; I want to avoid the temp var. Is that possible? var b holds a value between function calls because it is a memoization styled function.

  • IE browser script to determine which (if any) ActiveX control will handle specific mime type

    - by Jay13
    I'm trying to figure out in an IE script (javascript or vbscript) which ActiveX control will handle a specific mime type, "image/tiff" in this case. This is easy to do in other browsers that use plugins with; navigator.mimeTypes["image/tiff"].enabledPlugin.name which would return something like QuickTime Plug-in X.X.X I've found plenty of examples to tell if a specific plugin is loaded but since there are several plugins available that can handle tiff images I need to know which, if any, is registered to handle this mime type. The problem I'm trying to deal with is that QuickTime always wants to register itself as the default tiff viewer but it does a terrible job of it resulting in lots of support calls. Unfortunately, simply detecting that QuickTime is installed isn't good enough since the user may also have another tiff viewer installed (like Alternatiff) as the default tiff viewer or the user may have configured QuickTime to not be the default viewer for tiff images so the browser could be using a helper app to display the image instead. Not meaning to be difficult but before anyone suggests reengineering workarounds; yes I know I could force the user to use a specific ActiveX viewer in IE or to use a Java tiff viewer but I'd rather let them use a viewer of their choice rather than forcing them to install a viewer of my choosing, especially since their viewer may be a helper app that loads the tiff image into a business workflow within their office yes I know there are other image formats that I could use but tiff is the defacto standard for document imaging and that's what the vast majority of these users prefer to use. The problem isn't the image format, it's that QuickTime just doesn't cut it as a tiff viewer Thanks in advance for any suggestions or solutions...

  • Binary search of unaccesible data field in ldap from python

    - by EricR
    I'm interested in reproducing a particular python script. I have a friend who was accessing an ldap database, without authentication. There was a particular field of interest, we'll call it nin (an integer) for reference, and this field wasn't accessible without proper authentication. However, my friend managed to access this field through some sort of binary search (rather than just looping through integers) on the data; he would check the first digit, check if it was greater or less than the starting value, he would augment that until it returned a true value indicating existence, adding digits and continuing checking until he found the exact value of the integer nin. Any ideas on how he went about this? I've access to a similarly set up database.

  • Cannot write to SD card -- canWrite is returning false

    Sorry for the ambiguous title but I'm doing the following to write a simple string to a file: try { File root = Environment.getExternalStorageDirectory(); if (root.canWrite()){ System.out.println("Can write."); File def_file = new File(root, "default.txt"); FileWriter fw = new FileWriter(def_file); BufferedWriter out = new BufferedWriter(fw); String defbuf = "default"; out.write(defbuf); out.flush(); out.close(); } else System.out.println("Can't write."); }catch (IOException e) { e.printStackTrace(); } But root.canWrite() seems to be returning false everytime. I am not running this off of an emulator, I have my android Eris plugged into my computer via USB and running the app off of my phone via Eclipse. Is there a way of giving my app permission so this doesn't happen? Also, this code seems to be create the file default.txt but what if it already exists, will it ignore the creation and just open it to write or do I have to catch something like FileAlreadyExists(if such an exception exists) which then just opens it and writes? Thanks for any help guys.
