• Edit PDF files dynamically from Flash or Flex

  - by TandemAdam

  I am planning to do a CD-ROM in either Flash or Flex, possibly using the Adobe AIR runtime. This CD interactive will have a bunch of forms on it for the user to fill out. After they fill in a form, they will have the option of saving or printing a PDF that is based on there information. I am trying to find a way of editing the content of the PDF in Flash, so when the user fills out the form, the application will fill in the PDF with there details from the form fields. Is this is possible? It would be great if there was some way of having template PDFs (either on the CD as there own files, or in a Flash library), then flash could come along and fill in the specific fields inside the PDF. Can Adobe AIR help me in any way here?

• What to keep in mind when creating your own custom web services API?

  - by John Conde

  I have created a website which allows users to sign up for, and use, an online service. To help promote the website we will be have resellers who will be offering their own branded services through us. The initial plan is to allow resellers to place registration, login, and lost password forms on their own website and use an API created by us to handle these requests. I have begun outlining how I expect the API to work (and starting documenting it as well) and I want to make sure I get it right, or as close to right, as I can from the beginning as I know once you have declared a public API you want to avoid changing that API at all costs. So far I have decided: To have the user pass their account credentials with each request To require SSL for all requests What else should I be keeping in mind?

• Show file extensions in document libraries in Sharepoint 2010

  - by sebastian

  I've got a Sharepoint site collection with several sub sites each having their own document library. Now I want to add the file extensions to the document names in all those libraries. How should I do this? I've seen tips telling you to modify the onet.xml-file, but they never look like mine do, and furthermore I don't know for sure what happens to that onet.xml-file - does it change the existing libraries? Other tips tell me to use Sharepoint designer, that would mean I'll have to do it for every view in every library, wouldn't it? So I'd prefer doing it from code, where I feel more comfortable and where I can automate the process. So, all I want is to replace the "Name (linked to document with edit menu)" with the "Name (for use in forms)" but still keep the link and the edit menu. I've found I need to use the FileLeafRef-field, but I don't know how! Thankful for any new clues, Sebastian

• Strange CSS Positioning issue with a fader on a responsive site

  - by EPICWebDesign

  I'm developing a prototype responsive wordpress theme version of my homepage. I'm running into issues with the fader on the homepage. http://dev.epicwebdesign.ca/epicblog/ When the image switches, it uses position:absolute to overlay the pictures, then goes back to position:relative. I need to make the absolute be relative to the bottom left corner of the menu instead of the top left corner of #wrap so it doesn't overlap. I tried putting it in a container div like this: http://wiki.orbeon.com/forms/doc/contributor-guide/browser#TOC-Absolutely-positioned-box-inside-a-box-with-overflow:-auto-or-hidden but that doesn't seem to work. Any ideas? There are major CSS compatibility issues in IE, try it in chrome. It should look similar to http://epicwebdesign.ca. When the browser window is shrunk horizontially, the whole theme compensates.

• Replicating Active Directory - testing scenarios

  - by Naeem Sarfraz

  Replicating a production server's Active Directory is possible through a number of approaches as mentioned here and here. I'm looking for a simpler approach if one exists. I have a mixed-mode authentication site that I need to test. Quite simply AD users (internal) will have more privilege's than someone who logs in via forms (external). We have a web service that cache's an AD structure (users & groups). I'm thinking of building a module (http handler I guess?) that will pick up my specially formed URL (http://impersonateduser@localhost/mywebapp) and use the bit before the @ as the username. That will be the username I use for any subsequent operations. How does that sound? Has anyone got other proposals for testing scenarios like this?

• Alternatives to ASCX User Control without a server-side form?

  - by Andrew Murray

  I've got an ASP.NET 3.5 Web Forms application in which a large chunk of code needs to be duplicated between a few different pages. Sounds like the ideal candidate for a user-control right? Problem is, this cannot be contained within a <form runat="server"> because it contains a client-side form of it's own. There are no runat=server controls or postbacks or anything that really need that webform - think of it just as a chunk of HTML with a few basic <% %> tags. I'd just want to set a property on the control when it's loaded, so that it knows what to output. This is purely an exercise to make the code easier to maintain. Before I resort to using an oldskool <!--#include-->, is there some better way of doing this?

• Closing a dialog form closes the application

  - by user361633

  bool CheckAnswer() { DialogForm dialogForm = new DialogForm(); if (dialogForm.showDialog() == System.Windows.Forms.DialogResult.OK) return true; } The dialog form is invoked by a form created in the main form. When i close the dialog form the application is closed, not just the dialog form! If i invoke the dialog form in other form it works normally. The form from which i invoke the dialog form is top level, but even if i change that i'm getting the same result. Does anyone know what's wrong?

• Make Directory.GetFiles() ignore protected folders

  - by Kryptic

  Hello Everyone, I'm using the Directory.GetFiles() method to get a list of files to operate on. This method throws an UnauthorizedAccessException for example when trying to access a protected folder. I would like it to simply skip over such folders and continue. How can I accomplish this with either Directory.GetFiles (preferably) or another method? Update: Here is the code that throws the exception. I am asking the user to select a directory and then retrieving the list of files. I commented out the code (so this is now whole method) that iterates through the files and the problem still occurs. The exception is thrown on the Directory.GetFiles() line. FolderBrowserDialog fbd = new FolderBrowserDialog(); DialogResult dr = fbd.ShowDialog(); if (dr == System.Windows.Forms.DialogResult.Cancel) return; string directory = fbd.SelectedPath; string[] files = Directory.GetFiles(directory, "*.html", SearchOption.AllDirectories);

• How does .NET repaint controls?

  - by serhio

  Say I have a custom Label that I paint in my way. As lite example we have the code: Protected Overrides Sub OnPaint(ByVal e As System.Windows.Forms.PaintEventArgs) ' MyBase.OnPaint(e) DO NOT USE ' Dim f As Font = Me.Font Dim g As Graphics = e.Graphics Dim textRect As Rectangle = New Rectangle(Me.Location, Me.Size) Using br As New SolidBrush(Me._TextColor) g.DrawString(_Text, f, br, textRect) End Using End Sub maybe this example is useless, because does not bring different behavior that a simple label, but it just for example. Now, the problem is that if this label moves the ancient label area will not be updated, and the old text will remain until the parent will be invalidated. So the question is: How to invalidate the former control region?

• how to model editing of multiple related resources on the same webpage?

  - by amikazmi

  Lets say we have a Company model, that has many Employees And has many Projects If we want to show the projects, we'll go to "/company/1/projects/index" If we want to edit 1 project, we'll go to "/company/1/projects/1/edit" What if we want to edit all the projects at once on the same webpage? We can go to "/company/1/edit" and put a nested forms for all the projects But what if we need a different webpage to edit all the employees at once too? We can't use "/company/1/edit" again.. Right now we do "/company/1/projects/multiedit", "/company/1/projects/multupdate"- but as you can see, it's not rest. How can we model this restfully?

• Architecture Guidance for designing Workflow Foundation with WCF

  - by Matrix

  We are planning to use WF 3.5 with WCF 3.5 and Entity Framework 1.0 for the upcoming major project. I'm looking for guidance on the architecture side. This new application will be based on typical 3-tier architecture as depicted below: Presentation Tier: ASP.NET Web Forms 3.5 Business Tier: WF 3.5 + BLL's that expose the business logic through WCF service interfaces (using EF for Data Access) Data Tier: SQL Server 2000 Here are the questions: Though the Workflow Foundation has Workflow Services, where we can map the WCF service contracts to a workflow, is this the right way to design the applications? Is EF 1.0 business entities can be used in n-tier apps without sacrificing the tracking changes in the entities? Is there a sample reference application available to look? Thanks.

• User control blank on form in VS 2008

  - by Eric

  I've created a user control that contains a table layout control with various other standard controls like buttons and labels. Yet when I add the user control to one of my forms the control is blank. I've tried building the solution and a see the user-control flicker as if it's being updated, but it remains blank. Also if I actually run the program the usercontrol can not be see on the form. I've used usercontrols like this in the past. Is there something I'm missing?

• -1 as a return value

  - by dimadima

  This question is specifically about PHP, but I'm guessing it might be applicable to other languages as well. I've noticed that between PHP4 and PHP5, the designers of the language shifted away from using -1 as a return value to using constants or other forms of output. This makes sense, as -1 is not particularly evocative, and I'm guessing this practice led to confusion. That said, I am sometimes inclined to return -1 when I want to quickly add another return option to a function, and -1 often seems like a perfectly valid way to express the outcome I am coding for. So here are my questions: Is my observation generally correct, regarding the move away from -1 as a return value in PHP5 vs PHP4? What are the cons of returning -1, beyond for the reason I mentioned above, wherein the -1 return value doesn't contribute positively to code clarity?

• Calling member method on unmanaged C++ pointer from C# (I think)

  - by Jacob G

  I apologize in advance if this is a trivial question... I'm pretty C++ / unmanaged dumb. Here's a simplified analog to my setup: --In myUnmanagedObject.h in DLL: class myUnmanagedObject { public: virtual void myMethod(){} } --In MyControl.h in Assembly #1: #pragma make_public(myUnmanagedObject) [event_source(managed)] public ref class MyControl : public System::Windows::Forms::UserControl { public: myUnmanagedObject* GetMyUnmanagedObject(); } --in C# in Assembly #2: unsafe { MyControl temp = new MyControl(); myUnmanagedObject* obj = temp.GetMyUnmanagedObject(); obj-myMethod(); } I get a compile error saying that myUnmanagedObject does not contain a definition for myMethod. Assembly #2 references Assembly #1. Assembly #1 references DLL. If I compile the DLL with /clr and reference it directly from Assembly #2, it makes no difference. How, from C#, do I execute myMethod ?

• Hide other domains' menus from node edit form on a Drupal site using domain access

  - by monkeyninja

  I'm in the process of making some improvements to a live Drupal site that's using the Domain Access module to run a number of microsites. I'm trying to find a way of restricting the menus a user can post content to from the node edit screen. A user on one of the domains should only be able to post content to menus associated with that domain. Is there a simple way of achieving this? I'm guessing there are some hooks I could use, but so far I have been unable to identify them. I'd prefer not to have to install further modules to achieve this and to be able to add some code to the current site to alter the forms. The site is struggling with the large number of modules we've had to install on it already.

• How to modify the HTML and BODY tags in an ASP.NET page without adding runat=server to the elements?

  - by jon333

  In an ASP.NET web forms project that is not quite ready to be upgraded from 2.0 to 4.0 , there is a change that needs to be made to allow modifications to the HTML and BODY tags on the pages without adding runat=server to the tags which results in the 2.0 styled "ugly ids" like "ctrl_100..." For example, how could we change these using JavaScript, a Response Filter (the regex to find these specific tags would really help on this one), or something else...from: <html xmlns="//www.w3.org/1999/xhtml"> <body> To: <html lang="jp=JP" xmlns="//www.w3.org/1999/xhtml" dir="rtl"> <body dir="rtl"> JavaScript seems like a possibility, but functions from the server-side could would determine the language and direction the page should have.

• Unit Testing User Interface. What is an effective way ?

  - by pierocampanelli

  I have an accounting & payroll client/server application where there are several input form with complex data validation rules. I am finding an effective way to perform unit testing of user interface. For complex validation rules I mean: "Disable button X if I Insert a value in textfield Y" "Enable a combobox if I insert a value in a textfield" ...... ...... Most promising pattern i have found is suggested by M. Fowler (http://martinfowler.com/eaaDev/ModelViewPresenter.html). Have you any experience about Unit Testing of User Interface? As technology stack I am using: .NET 3.5 & Windows Forms Widget Library.

• Browser application & local file system access

  - by Beyond HTML

  I want to enhance my browser-based web application with functionality that enables management of local files and folders. E.g. folder tree structures should be synchronized between local workstation and server via HTTP(S). I am aware of security-related limitations in browser-based applications. However, there are some techniques that "work around" these issues: Signed Java applets (full trust) .NET Windows Forms browser controls (no joke, that works. Just the configuration is horrible) ActiveX My question is: What do you use/suggest, both technology and implementation practice? Key requirement is that the installation process is as simple as possible. Thanks for your opinions!

• cancel button not working in iframe but working when using url for the page

  - by user1327358

  I am working on a form that includes a cancel button. The button correctly closes the form if it is accessed directly through a URL. But once the form is placed in an iframe, the cancel function does not work. Can you please help? Here is the code: public class Cancell extends com.ford.forms.types.Button { /** * Cancel constructor comment. */ public Cancell() { setImageName("../images/cancel.png"); setOnClickScript("if (confirm('This selection will clear your entries and close this form. Click OK to close this form.')) {document.formApp.Command.value='Cancel';window.close();}"); //setOnClickScript("window.close();"); } }

• Multiple Payment options within the same order

  - by Rob Y

  I have a requirement to be able to accept different forms of payment within the same order - ie not just the usual credit card or paypal for the whole thing, but perhaps paypal for one item, cheque for another. I know this sounds quite crazy, but there is a good business reason for the requirement so I can't just push back. The best way I can think of implementing it at the moment is to have kind of a hub page, where you can "launch off" into multiple flows for each of the payments by opening new windows. I can't figure out a way of doing this in a linear flow as for example you can't guarantee that a user will come back from paypal, so you'd then lose the user completely. Is there a neater way of doing this that anyone can think of, or can anyone point me to an example of a site that does somethign similar for inspiration?

• Move Global.asax to iHttpModule when using ASP.NET MVC

  - by rockinthesixstring

  I have successfully created an iHttpModule to replace my Global.asax file in many Web Forms applications. But in looking at the Global.asax file in my MVC application, the methods are totally different. I'm wondering if it is still possible to create this same thing in an MVC app. I know it's not necessary and the Global.asax works just fine. I suppose I just want to have nothing but the web.config in the root directory of my application. Also, I am putting all of my classes in a separate class library project instead of a folder in my MVC application. Not sure if this makes a difference or not.

• Howto Plot "Reverse" Cumulative Frequency Graph With ECDF

  - by neversaint

  I have no problem plotting the following cumulative frequency graph plot like this. library(Hmisc) pre.test <- rnorm(100,50,10) post.test <- rnorm(100,55,10) x <- c(pre.test, post.test) g <- c(rep('Pre',length(pre.test)),rep('Post',length(post.test))) Ecdf(x, group=g, what="f", xlab='Test Results', label.curves=list(keys=1:2)) But I want to show the graph in forms of the "reverse" cumulative frequency of values x ? (i.e. something equivalent to what="1-f"). Is there a way to do it? Other suggestions in R other than using Hmisc are also very much welcomed.

• Automated browsing with javascript?

  - by Paul Wicks

  I'm trying to do some browser automation, but I'm having some problems. Basically, what I'd like to do is load a set pages, set some forms options, click a button and view the results for each page that I open. Originally, I tried to do this by placing the pages I wanted to automate in iframes and then using javascript to drive the interactions I want in each, but that results in a Permissions Error, since the sites I want to automate are not on my server. Is there any way around this? The other possibility I've thought of is to use QT's webkit class and the evaluateJavaScript method to accomplish what I'd like to do, but this seems a bit more heavy weight for something that is, conceptually, pretty simple.

• Automating site interaction

  - by Leocer

  I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.
