  • Changing mouse cursor in Share Point

    - by ephieste
    I designed a Share Point page in Share Point Designer. ( I cannot upload anything to the servers or no chance to use add-ons) Since it is requested I have to change the shape of mouse cursor. Some purple bubbles or a logo should follow the original mouse cursor when I move the mouse. How can do this? If I find the code where (in which file) should I put it? Can it be done with site based design? Thank you very much

  • PHP email form multiple select

    - by Justin Goodman
    I'm trying to set up a simple PHP contact form for a website and I need some help modifying the PHP to list multiple items from a select menu and would appreciate the help. I'm a graphic designer, not a developer, so a lot of this is way over my head. This is the problem area here: <label for="Events[]">Which Event(s) Will You Be Attending?</label> <div class="input-bg"> <select name="Events[]" size="6" multiple="MULTIPLE" class="required" id="Events[]"> <option value="Wednesday">Portfolio Show June 16</option> <option value="Thursday">Portfolio Show June 17</option> <option value="Saturday">Graduation Ceremony</option> <option value="Saturday Eve">Graduation Party</option> <option value="Not Sure">Not Sure</option> <option value="Not Coming">Not Coming</option> </select> </div> And here's the PHP: <?php // CHANGE THE VARIABLES BELOW $EmailFrom = "[email protected]"; $EmailTo = "[email protected]"; $Subject = "Graduation RSVP"; $Name = Trim(stripslashes($_POST['Name'])); $Email = Trim(stripslashes($_POST['Email'])); $Guests = Trim(stripslashes($_POST['Guests'])); $Events = Trim(stripslashes($_POST['Events'])); // prepare email body text $Body = ""; $Body .= "Name: "; $Body .= $Name; $Body .= "\n"; $Body .= "Email: "; $Body .= $Email; $Body .= "\n"; $Body .= "Guests: "; $Body .= $Guests; $Body .= "\n"; $Body .= "Events: "; $Body .= $Events; $Body .= "\n"; // send email $success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>"); // redirect to success page // CHANGE THE URL BELOW TO YOUR "THANK YOU" PAGE if ($success){ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation\">"; } else{ print "<meta http-equiv=\"refresh\" content=\"0;URL=http://justgooddesign.net/graduation/error.html\">"; } ?> Any help really is appreciated!

  • Power Analysis in [R] for Two-Way Anova

    - by Thomas
    I am trying to calculate the necessary sample size for a 2x2 factorial design. I have two questions. 1) I am using the package pwr and the one way anova function to calculate the necessary sample size using the following code pwr.anova.test(k = , n = , f = , sig.level = , power = ) However, I would like to look at two way anova, since this is more efficient at estimating group means than one way anova. There is no two-way anova function that I could find. Is there a package or routine in [R] to do this? 2) Moreover, am I safe in assuming that since I am using a one-way anova power calculations, that the sample size will be more conservative (i.e. larger)?

  • Dynamically showing fields to a Dev Express Grid view on windows form

    - by Bhaskar
    In one of windows application in C# , I am using Dev Express Grid view control to bind some data and display it to user. I have custom business objects with properties defined for this purpose.Then I simple set the DataSource of the grid to the list of my custom business objects. A while ago , there came a requirement which means that the columns to be displayed on to the grid will be dynamic. This means I cannot know at design time which fields I will need to display. I was thinking of abandoning setting the DataSource and populating the grid manually by code. But I think this will cause many of the grid's features not to work properly, for example , grouping the data by drag n drop of fields to the header area etc. Is there any way to tell a grid at runtime to skip certain fields from a list of BO's when databinding to the grid ?

  • Override transparency color when converting transparent PNG to JPG

    - by Alexander Malfait
    I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

  • Designing DAL in .NET to be "data-source independent" and not just "database independent" ?

    - by Munish Goyal
    How to design such flexible DAL (specifically in .NET) ? What interfaces .NET provides and what should be done on my own ? Its a greenfield project starting with SQL Server as data source but in future, parts of it will move to different NoSQL type of datastores. Also, we may need to experiment with lot of different datastores (like some data may have to go with Cassandra, some with RDBMS, some to other DHT etc.) Therefore easily switchable access layer will be needed. All i know right now is the 'data' and 'operations needed on that data'.

  • Why are hidden fields used?

    - by Pavan Reddy
    I have always seen a lot of hidden fields used in web applications. I have worked with code which is written to use a lot of hidden fields and the data values from the visible fields sent back and forth to them. Though I fail to understand why the hidden fields are used. I can almost always think of ways to resolve the same problem without the use of hidden fields. How do hidden fields help in design? Can anyone tell me what exactly is the advantage that hidden fields provide? Why are hidden fields used?

  • Using jQuery to create a video switcher

    - by techcastoni
    I've got a design for a video page which has a main video panel which will load the FLV file into JWPlayer when a thumbnail image is clicked. I think what I'm looking for is a partial page refresh? What is the best way to achieve this effect? This is the script I am using to display the video panel: var s1 = new SWFObject('player.swf','player','682','407','9'); s1.addParam('allowfullscreen','true'); s1.addParam('allowscriptaccess','always'); s1.addParam('flashvars','file=Welcome.f4v'); s1.write('preview');

  • How to achieve the recessed text style as in Apple's Messages for Mac?

    - by Thruth
    I'd like to replicate the recessed text style of Messages/iMessage, or, the text "white-shadow" style on a light gray background. Please refer to an image here for the style I desire. As you can see, the texts are with "white-shadow" even on the light gray background. The bold texts do have subpixel rendering while the gray texts don't (by design?). I've tried setBackgroundStyle:NSBackgroundStyleRaised . However it was generating shadows darker than the background. setBackgroundStyle:NSBackgroundStyleLowered was worse that it even overrode my font colour setting. So, what is the right way to do this? Any tricks or just have to subclass NSTextFields ? Thanks.

  • Can't change header logo in Magento?

    - by Jared
    Hello, I have created my own theme for magento, and I am trying to edit the logo and am having difficulty. I have created my own local/Mage/Page/etc/config.xml file, and specified within the config the following: <logo_src>images/Race-Ramps-logo-streaked-gradient.gif</logo_src> I created a custom layout in the file as well. I can see the custom layout file in the CMS, but my changes to the logo do absolutely nothing. I have even tried changing the original core config.xml, it still stays the same. On multiple websites, I have been told to go to System Configuration Design Header, but I do not have the header option? Help please!

  • How to plan my web based project before starting code ?

    - by Arsheep
    Me and my friend started working together as partners , we have decided to make Kick-as* website after website. We have the ideas written down like 100's of them (yes we are choosing best and easy among them first). My friend does the layout design and arranging things , and my part is coding and server management. The little problem i am facing is lack of experience in planing a project. What i do is, I just start the code straight away and along with code I make DB, like when i need a table i make it. I know this is very bad approach for a medium sized project. Here at stackoverflow i saw lots of experienced coders. Need to learn a lot from you guys :) . So can you plese help me on how to plan a project and what coding standard/structure/frameworks to be used (I do PHP code). Thanks in advance.

  • bad performance from too many caught errors?

    - by Christopher Klein
    I have a large project in C# (.NET 2.0) which contains very large chunks of code generated by SubSonic. Is a try-catch like this causing a horrible performance hit? for (int x = 0; x < identifiers.Count; x++) {decimal target = 0; try { target = Convert.ToDecimal(assets[x + identifiers.Count * 2]); // target % } catch { targetEmpty = true; }} What is happening is if the given field that is being passed in is not something that can be converted to a decimal it sets a flag which is then used further along in the record to determine something else. The problem is that the application is literally throwing 10s of thousands of exceptions as I am parsing through 30k records. The process as a whole takes almost 10 minutes for everything and my overall task is to improve that time some and this seemed like easy hanging fruit if its a bad design idea. Any thoughts would be helpful (be kind, its been a miserable day) thanks, Chris

  • Infopath form publishing and root content type ?

    - by Steve B
    Hi, I have several infopath 2010 form template that I want to publish to a form library in SharePoint 2010 Server with enterprise CaL. All of this forms have a common part (a template part actually). Is it possible to define a common "parent" content type of this forms ? In fact, I want : Form content type (SP OOB) My root form content type, with standard columns "requester", "process name", etc. Form 1 Form 2 etc. other unrelated form 1 other unrelated form 2 Instead of the standard behavior : Form content type (SP OOB) Form 1 Form 2 other unrelated form 1 other unrelated form 2 etc. Behind this question I want to be able to create a dashboard of all form request using a content query web, by simply specifying the content type ... One last word: the idea is to allow a customer (assuming its knowledge is limited to IP 2010 basic form design). So I can't accept answers like "extract files, use a text editor and hack the xsf file"... thx in advance

  • Silverlight Pixel Shader resource "not found"; what should the URI be?

    - by Grank
    So I've written and compiled an HLSL pixel shader with Shazzam, placed the resulting .ps file in my project, and am trying to instantiate it. No matter what URI I put, Blend tells me that the resource can't be found whenever I try to view any xaml designer, and Visual Studio just shows me a blank page, both in design view and if I try to run the application. This is a Silverlight 4 SketchFlow project, in Blend 4 RC and Visual Studio 2010. I've tried both Resource and EmbeddedResource as the Build Action for the .ps file, neither make any difference (I'm pretty sure it's supposed to be set to Resource). I've tried the following URI formats: "ShaderFileName.ps" "/ShaderFileName.ps" "AssemblyName;component/ShaderFileName.ps" "/AssemblyName;component/ShaderFileName.ps" I also tried moving the shader file from the Screens assembly to the root assembly (that's how SketchFlow projects are created) and that didn't help either. Anyone have any thoughts?

  • Where does complexity bloat from?

    - by AareP
    Many of our design decisions are based on our gut feeling about how to avoid complexity and bloating. Some of our complexity-fears are true, we have plenty of painful experience on throwing away deprecated code. Other times we learn that some particular task isn't really that complex as we though it to be. We notice for example that upkeeping 3000 lines of code in one file isn't that difficult... or that using special purpose "dirty flags" isn't really bad OO practice... or that in some cases it's more convenient to have 50 variables in one class that have 5 different classes with shared responsibilities... One friend has even stated that adding functions to the program isn't really adding complexity to your system. So, what do you think, where does bloated complexity creep from? Is it variable count, function count, code line count, code line count per function, or something else?

  • Writing asynchronously on a stream in cocoa

    - by Richard Ibarra
    Hi folks I have been trying to find any way for writing asynchronously on a stream in Cocoa. I have a set of events in my applications which will try to send data through the socket but i can't be blocked during this transmission due to design terms. I have tried setting a delegate on the output stream and check the event NSStreamEventHasSpaceAvailable but I don't know how this can be combined with the events that put data into the stream. Is there anyway for doing that? I thought using NSThread but I guess there is a better option. Cheers

  • Location of my own directories

    - by Nicsoft
    Hello, I am trying to understand how to create my own directory tree and access it from my application. I am doing some kind of learning program and want to create a directory structure like this: -MyLessonsDirectory --LessonDirectory_1 ---Step_1 ---Step_2 ---Step_3 --LessonDirectory_2 ---Step_1 ---Step_2 ---Step_3 . . and so on In each "Step"-directory I will have specific content for that step of the lesson. The content is added by me while developing. Hence, I don't want to create the structure and content from within the application, just access it and reading the content of the directories. If I can create this kind of structure and use it it will be very easy to create a nice design that makes it easy to create new lessons in my app. What I cannot figure out is where I should create those directories in the file-structure in xCode and what is the path to those directories from my application. Thanks in advance!

  • How to obtain Bing maps like InfoWindow in Google Maps?

    - by BillB
    I'm using Google Maps v3. I really like the InfoWindows found in Bing, as opposed to Google. Screenshots & functionality found here comparing the two: http://www.axismaps.com/blog/2009/07/data-probing-and-info-window-design-on-web-based-maps/ Question: How can I replicate Bing like InfoWindows while using Google Maps v3? UPDATE: To be more specific, what I like about Bing's InfoWindows include: - The pointer dynamically changes sides from left/right/bottom/top, as opposed to Google limited to only have the InfoWindow pointer on the bottom - Bing's InfoWindows use less space - You can configure Bing's InfoWindows to pop up outside of the map bounders so that you don't have to autopan the map to display the marker's InfoWindow

  • Is it possible to provide a resize indication (resizer-grip) on a form without adding a status bar?

    - by Marek
    I would like to have a resize indication on a windows forms Form (the same resize-grip as when you have a status bar). I do not want to add a status bar to the form - that would break the design of the form. The form can have various controls inside that are docked (Fill). I have not found any solution to this besides drawing the resize indication in lower right corner of every control, which is not very feasible. Is this possible without adding a picture of the resize grip to every control that can be docked in the form?

  • building a web application in eclipse

    - by Noona
    As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

  • Do you use enums in your data applications and how?

    - by Ivan
    My practice shows that a general enterprise application has a lot of entities which's nature corresponds to an elementary enumeration. For example We may have an Order entity which may have such fields as "OrderType", "OrderStatus", "Currency", etc. referencing corresponding Entities which are nothing more than just a textual name bound to a key to be referenced. Using enums would look very natural here. But entities have to be defined in application code at design-time, am I right? While in we need to be able to CRUD enum value variants at runtime and use enums in server-side SQL queries (like stored procedures and views). What are you practices and thoughts on this subject? I am particularly interested in C#4, linq and T-SQL.

  • Cocoa Key event problem

    - by Oscar
    I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?
