• Perl Script in background

  - by himz

  I have a perl script i made to automatically telnet into different servers . but its interface is only command line. To make it more user friendly for general windows users , i need to make GUI for it . My idea is to make GUI in a language like VB,java ,etc and let that call perl script . my script will run in background in a command prompt and whatever the result it displays back in GUI. Got some success. GUI in vb ,I run an instance of CMD in background ,run perl script in that .But that is wer program fails .As perl script runs in a thread for perl , i only get the output when script completes(rather say when it timeout). i need a mechanism where i can interact with the perl script , take output of script and show to user , then take input from user and so on . Please can you all suggest me some way to actually make this happen. PS: No limitation on using any language for GUI (as core work is done by perl script,GUI only there to give appropriate commands to script) Thanks in advance

• Forms/AD Authentication with Sharepoint

  - by David Lively

  All, I'm configuring Sharepoint to use forms authentication with LDAP/Active Directory. I'm new to Sharepoint, so if this is obvious, please point me in the right direction. Whenever I attempt to log in with a bad account or password, I get the very friendly (and correct) error message, The server could not sign you in. Make sure your user name and password are correct, and then try again. ... which implies that Sharepoint is able to communicate with AD. If I log in with a valid account, I get a page that says: (I added the grey bar to cover up the login name) Any suggestions? The account I'm logging in with is an administrator and has been granted full control in central administration. Also, interesting note: If I click the "sign in as a different user" link, and attempt to sign in using with the same credentials I just used, the site just redirects back to the login page, with no error or status message. If I then manually enter the site url, it again shows the "Error: Access Denied" page. Argh.

• suggestions for a 3D graph rendering library?

  - by Sandro

  Hello coders! So I'm not sure how stackoverflow friendly this question is since it doesn't have a quick clear cut answer but here we go... I have a java program that generates data for a directed graph. Now I need to render this graph. The data needs to be laid out in 3D, and I want to be able to define which plane an edge lives in. (Each edge will only need to occupy 1 plane of the 3D space). I also need the ability to navigate around the graph. Since I know that this kind of stuff is hard, I'm going shopping. So far I've looked into (In no particular order): JUNG: lacks 3D support Cytoscape: not sure how much I'll be able to define edge drawing, haven't seen a non bio-informatics application of it yet JGraph: I didn't see any 3D applications yet Perfuse: looks promising, does anyone know anything else about it? Gephi: Documentation looks scarce Processing: does this play well with java? I'm also considering doing some combination of opengl + swing rendering to create a 3D graph from multiple 2D graphs. I am also not adverse to the idea of linking from another language Any Ideas? Thank you.

• problem with RenderOuterTable property for .net 4.0 controls

  - by Mario

  According to the new 4.0 framework overview, one should be able to add the attrib RenderOuterTable="false" to a control that supports the attribute and see css friendly code be spit out - in other words no html tables. To test this, I threw a login control into a basic fresh webpage with the following code: <asp:Login ID="Login1" runat="server" RenderOuterTable="false"></asp:Login> The result? Crappy html table output, which supposedly doesn't happen with this attrib set to false. Here is the output: &lt;table cellpadding=&quot;0&quot;&gt; <tr> <td align="center" colspan="2">Log In</td> </tr><tr> <td align="right"><label for="MainContent_Login1_UserName">User Name:</label></td><td><input name="ctl00$MainContent$Login1$UserName" type="text" id="MainContent_Login1_UserName" /><span id="MainContent_Login1_UserNameRequired" title="User Name is required." style="visibility:hidden;">*</span></td>... Hopefully you get the point. Anyone know how to stop these controls from outputting tables? This is super annoying.

• How to add and relate a node within the parent nodes add form in Drupal.

  - by Espen Christensen

  Hi, I want to accomplish the following scenario in Drupal: You have 2 content-types. Lets say, an application-form for a lisence, and a content-type for persons. Then when you go to add a lisence in the "node/add" submission form in Drupal, i would like to add a relative number of persons that would be related to this lisence, and only this lisence. Say you would like to apply for a lisence, and relate 4 persons to this lisence, then insted of creating the lisence and then create the 4 persons and relate them to the lisence, i would like to do this "inline". So when i add a lisence, there would be a way to add 1 or more persons that would relate to the lisence node. Is this possible, and if so how? I have been looking at the node reference module, and that manages to reference a node to another, but not to add them inline with the other. With the web-development framework Django, there is a way to this with something called "inline-editing", where you get the content-type fields inside another content-type creation form. There you bind them togheter with a ForeignKey. Anybody know of something simular in Drupal, if not, is it another way to achive something simular, that would be as user-friendly?

• Parsing multibyte string in PHP

  - by Petr Peller

  I would like to write a (HTML) parser based on state machine but I have doubts how to acctually read/use an input. I decided to load the whole input into one string and then work with it as with an array and hold its index as current parsing position. There would be no problems with single-byte encoding, but in multi-byte encoding each value does not represent a character, but a byte of a character. Example: $mb_string = 'žšcr'; //4 multi-byte characters in UTF-8 for($i=0; $i < 4; $i++) { echo $mb_string[$i], PHP_EOL; } Outputs: L ž L A This means I cannot iterate through the string in a loop to check single characters, because I never know if I am in the middle of an character or not. So the questions are: How do I multi-byte safe read a single character from a string in a performance friendly way? Is it good idea to work with the string as it was an array in this case? How would you read the input?

• Ideas for a rudimentary software licensing implementation

  - by Ross

  I'm trying to decide how to implement a very basic licensing solution for some software I wrote. The software will run on my (hypothetical) clients' machines, with the idea being that the software will immediately quit (with a friendly message) if the client is running it on greater-than-n machines (n being the number of licenses they have purchased). Additionally, the clients are non-tech-savvy to the point where "basic" is good enough. Here is my current design, but given that I have little to no experience in the topic, I wanted to ask SO before I started any development on it: A remote server hosts a MySQL database with a table containing two columns: client-key and license quantity The client-side application connects to the MySQL database on startup, offering it's client-key that I've put into a properties file packaged into the distribution (I would create a new distribution for each new client) Chances are, I'll need a second table to store validation history, so that with some short logic, the software can decide if it can be run on a given machine (maybe a sliding window of n machines using the software per 24 hours) If the software cannot establish a connection to the MySQL database, or decides that it's over the n allowed machines per day, it closes The connection info for the remote server hosting the MySQL database should be hard-coded into the app? (That sounds like a bad idea, but otherwise they could point it to some other always-validates-to-success server) I think that about covers my initial design. The intent being that while it certainly isn't full-proof, I think I've made it at least somewhat difficult to create an easily-sharable cracking solution. Also, I can easily adjust the license amount for a given client/key pair. I gotta figure this has been done a million times before, so tell me about a better solution that's just as simple to implement and provides the same (low) amount of security. In the event that external libraries are used, I prefer Java, as that's what the software has been written in.

• How to use the Request URL/URL Rewriting For Localization in ASP.NET - Using an HTTP Module or Globa

  - by LocalizedUrlDMan

  I wanted to see if there is a way to use the request URL/URL rewriting to set the language a page is rendered in by examining a portion of the URL in ASP.NET. We have a site that already works with ASP.NET’s resource localization and user’s can change the language that they see pages/resources on the site in, however the current mechanism in not very search engine friendly since the language variations for each language all appear as one page. It would be much better if we could have pages like www.site.com/en-mx/realfolder/realpage.aspx that allow linking to culture specific versions of a page. I know lots of people have likely done localization through URL structures before and I wanted to know if one of your could share how to do this in the Global.asax file or with an HTTP Module (pointing to links to blog postings would be great too). We have a restriction that the site is based on ASP.NET 2.0 (so we can't used the 3.5+ features yet). Here is the example scenario: A real page exits at: www.site.com/realfolder/realpage.aspx The page has a mechanism for the user to change the language it is displayed in via a dropdown. There are search engine optimization and user links sharing benefits to doing this since people can link directly to a page that has content that is applicable to a certain language (this could also include right-to-left layouts for languages like Japanese). I would like to use an HTTP module to see if the first part of the URL after www.site.com, site.com, subdomain.site.com, etc. contains a valid culture code (e.g. en-us, es-mx) then use that value to set the localization culture of the page/resources based on that URL. So if the user accesses the URL www.site.com/en-MX/realfolder/realpage.aspx Then the page will render in Mexico’s variant of Spanish. If the user goes to www.site.com/realfolder/realpage.aspx directly the page would just use their browser’s language settings.

• Looking for recommnedation on JavaScript libraries in the leage of ExtJS and Qooxdoo for serious web

  - by Kabeer

  Hello. I'm looking for a JavaScript library for my web application. The application is very data intensive and has rich form controls (almost windows like). AJAX will be used liberally. The development platform is ASP.Net (mostly ASP.Net MVC will be used). I cannot pursue with ExtJs due to the price/license factor. I checked Qooxdoo but it is very windows-unfriendly. YIU fell short of my needs w.r.t. form controls it offers. Other libraries like jQuery do not offer rich form controls. So I am looking recommendations for a library that satisfies most of following needs: Rich UI controls Solid API for AJAX handling Employs good programming practices for scripting in frontend (preferably OO but not mandatory) Free. Else has only development cost and not production Windows friendly (or at least not unfriendly) Not monolithic. Should be independent (Not have development & production dependencies) Theme'ing should be easy (preferably wrapped by the library) I am not mentioning other basic needs (like browser compatibility). I hope any popular library will honor those.

• Which SCM/VCS cope well with moving text between files?

  - by pfctdayelise

  We are having havoc with our project at work, because our VCS is doing some awful merging when we move information across files. The scenario is thus: You have lots of files that, say, contain information about terms from a dictionary, so you have a file for each letter of the alphabet. Users entering terms blindly follow the dictionary order, so they will put an entry like "kick the bucket" under B if that is where the dictionary happened to list it (or it might have been listed under both B, bucket and K, kick). Later, other users move the terms to their correct files. Lots of work is being done on the dictionary terms all the time. e.g. User A may have taken the B file and elaborated on the "kick the bucket" entry. User B took the B and K files, and moved the "kick the bucket" entry to the K file. Whichever order they end up getting committed in, the VCS will probably lose entries and not "figure out" that an entry has been moved. (These entries are later automatically converted to an SQL database. But they are kept in a "human friendly" form for working on them, with lots of comments, examples etc. So it is not acceptable to say "make your users enter SQL directly".) It is so bad that we have taken to almost manually merging these kinds of files now, because we can't trust our VCS. :( So what is the solution? I would love to hear that there is a VCS that could cope with this. Or a better merge algorithm? Or otherwise, maybe someone can suggest a better workflow or file arrangement to try and avoid this problem?

• yahoo's attribute exchange -> blank data is coming

  - by Gaurav Sharma

  Hello everybody, I am trying to build openid login system for my website. To do this I used JanRain's php openid library v 2.1.3. I am also using openid selector to select the openid provider from the list. I first created the attributes array that I need to fetch from the provider as follows: $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/contact/email',2,1, 'email'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/first',1,1, 'firstname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/last',1,1, 'lastname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson',1,1, 'fullname'); $attribute[] = Auth_OpenID_AX_AttrInfo::make('http://axschema.org/namePerson/friendly',1,1, 'username'); $ax = new Auth_OpenID_AX_FetchRequest; foreach($attribute as $attr) { $ax-add($attr); } $auth_request-addExtension($ax); and in the finish_auth.php file I wrote this to fetch the attributes returned $ax = new Auth_OpenID_AX_FetchResponse(); $obj = $ax-fromSuccessResponse($response); Google gives me all the attributes requested but yahoo doesn't (as stated here that yahoo now supports attribute exchange). Is there any limitation set by yahoo on attribute exchange too. (they give limited websites access to sreg extension of openid). :( Please help me, I am stuck over here. Thanks

• Design suggestions for creating document management structure using hidden shares.

  - by focus.nz

  I need to add some document management functionality into my software. Documents will be grouped by company name and project name. The folders need to be accessed by the application using the id numbers of clients/projects, but also easily browsed by the end user using windows explorer. Clients and Projects will be stored in a database. I am thinking of having the software create the folders using the friendly name and then using a hidden share with the id number for the software to access the files. The folder structure would be something like this --Company 1 (Company-1234$) -- Project 101 (Project-101$) -- Project 102 (Project-102$) -- Project 103 (Project-103$) -- Company 2 (Company-5678$) -- Project 201 (Project-201$) -- Project 202 (Project-202$) -- Project 203 (Project-203$) So in the example above there would be a company called "Company 1" with a ID of "1234". When browsing the folders using windows explorer the user would see \\ServerName\Documents\Company1 and you could also access the same folder from \\ServerName\Documents\Company-1234$ By using the hidden share, if the company name changes or its renamed for some reason it doesn't break the link in the application because its using the hidden shared based on the ID that never changes. Will having hundreds (maybe thousands) or hidden shares on a server provide a huge performance hit? Does any one have any suggestions or alternatives to provide this feature?

• Dependency Injection and decoupling of software layers

  - by cs31415

  I am trying to implement Dependency Injection to make my app tester friendly. I have a rather basic doubt. Data layer uses SqlConnection object to connect to a SQL server database. SqlConnection object is a dependency for data access layer. In accordance with the laws of dependency injection, we must not new() dependent objects, but rather accept them through constructor arguments. Not wanting to upset the DI gods, I dutifully create a constructor in my DAL that takes in SqlConnection. Business layer calls DAL. Business layer must therefore, pass in SqlConnection. Presentation layer calls Business layer. Hence it too, must pass in SqlConnection to business layer. This is great for class isolation and testability. But didn't we just couple the UI and Business layers to a specific implementation of the data layer which happens to use a relational database? Why do the Presentation and Business layers need to know that the underlying data store is SQL? What if the app needs to support multiple data sources other than SQL server (such as XML files, Comma delimited files etc.) Furthermore, what if I add another object upon which my data layer is dependent on (say, a second database). Now, I have to modify the upper layers to pass in this new object. How can I avoid this merry-go-round and reap all the benefits of DI without the pain?

• Localization: How to allow the user to define custom resources without compiling?

  - by gehho

  In our application, we have a collection of data items, each with a DisplayedName property. This property should be localized, i.e. it should be displayed in the language selected by the user. Therefore, another property, DisplayedNameResourceKey, specifies which resource should be returned by the DisplayedName property. In simplified code this means something like this: public string DisplayedName { get { return MyResources.ResourceManager.GetObject(this.DisplayedNameResourceKey); } } public string DisplayedNameResourceKey { get; set; } Now, the problem is: The user should be able to edit these items including the DisplayedName, or more precisely the DisplayedNameResourceKey. And not only this, but the user should also be able to somehow define new resources which he can then reference. That is, he can either choose from a predefined set of resources (some commonly used names), or define a custom resource which then needs to be localized by the user as well. However, the user cannot add custom resources to MyResources at runtime and without compiling. Therefore, another approach is needed. It does not have to be an extremely user-friendly way (e.g. UI is not required) because this will typically be done by our service engineers. I was thinking about using a txt or csv file containing pairs of resource keys and the corresponding translations. A separate file would exist for every language at a predefined location. But I am not really satisfied with that idea because it involves a lot of work to resolve the resources. Does anyone know a good approach for such a situation?

• Packaging reference documentation with jar file

  - by soren.enemaerke

  We are porting our .NET library to a java equivalent and is now looking at how to distribute this port. Packaging the classes into a jar-file seems like best practice and we would then ship this jar file in a zip along with some license terms. But what about the documentation? In .NET land it seems like best practice to distribute the xml file that can be consumed by tooling (Visual Studio) but we can't seem to find such best practices for java. We have javadoc comments on our public classes and interfaces, so we are just looking for a way to generate and distribute these comments in a way that is developer friendly (we're thinking easily consumed from various IDEs). What are developers expecting and how do you best deliver this? We would really prefer to bundle the documentation along with the jar file and not have to host the documentation on our website EDIT: We would like for our documentation to appear inside the java IDEs so we want to provide the documentation in a way that integrates into the IDEs as gracefully as possible. In .NET land this is as an xml file placed next to the .dll file, but is there a similar concept for jar files that enables the integration into tooling? PS: We are developing in Eclipse and have an ant task doing the building and jar-file packaing in our automated build.

• Search book by title, and author

  - by Swoosh

  I got a table with columns: author firstname, author lastname, and booktitle Multiple users are inserting in the database, through an import, and I'd like to avoid duplicates. So I'm trying to do something like this: I have a record in the db: First Name: "Isaac" Last Name: "Assimov" Title: "I, Robot" If the user tries to add it again, it would be basically a non-split-text (would not be split up into author firstname, author lastname, and booktitle) So it would basically look like this: "Isaac Asimov - I Robot" or "Asimov, Isaac - I Robot" or "I Robot by Isaac Asimov" You see where I am getting at? (I cannot force the user to split up all the books into into author firstname, author lastname, and booktitle, and I don't even like the idea to force the user, because it's not too user-friendly) What is the best way (in SQL) to compare all this possible bookdata scenarios to what I have in the database, not to add the same book twice. I was thinking about a possibility of suggesting the user: "is THIS the book you are trying to add?" (imagine a list instead of the THIS word, just like on stackoverflow - ask question - Related Questions. I was thinking about soundex and maybe even the like operators, but so far i didn't get the results i was hoping.

• return sql query in xml format in python

  - by Ramy

  When I first started working at the company that i work at now, I created a java application that would run batches of jasper-reports. In order to determine which parameters to use for each report in the set of reports, I run a sql query (on sqlserver). I wrote the application to take an xml file with a set of parameters for each report to be generated in the set. so, my process has become, effectively, three steps: run the sql query and return the results in XML format (using 'for XML auto') run the results of the sql query through an XSLT transformation so the xml is formatted in such a way that is friendly with the java application i wrote. run the java application with that final xml file As you can imagine, what I'd like to do is accomplish these steps in python, but i'm not quite sure how to get started. I know how to run an SQL query in Python. I see plenty of documentation about how to write your own xml document with Python. I even see documentation for xsl transformations in python. the big question is how to get the results of the sql query in XML through python. Any and all pointers would be very valuable.

• How to add text to email sent from a php contact form

  Hi all this is the PHP im using: <?php $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $message = $_POST['message']; $formcontent=" From: $name \n Phone: $phone \n Message: $message"; $recipient = "[email protected]"; $subject = "Contact Form"; $mailheader = "From: $email \r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none; color:#ff0099;'> Return Home</a>"; ?> Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the: mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); line but with no success. Thanks for taking the time any help would be welcome.

• Password Confirmation Overlay

  - by Alasdair

  Hello, I'm creating a J2EE web application that uses jQuery and Ajax to help with some of the presentation for a user-friendly interface. I've done a lot of work ensuring security around persistant login cookies, and I've decided to request the password from any user that logged in using a persistant login cookie before being allowed to make any changes that could be malicious. This request would only happen once to confirm the user is who they say they are and will last throughout the session. At present, any requests that meet this criteria has their request information stored in session and then the user is forwarded to a page to confirm their password. Once confirmed, the user's original request is then performed and the requestion information removed from session. What I would like to do is avoid all this redirection and minimize what's held in session (even if it's just for a small time), thus improving usability and convenience for the user. I believe that a jQuery overlay could allow me to prompt the user for their password (if required) and then continue to submit the request if successful. I would of originally used ThickBox, but since that's now deprecated I don't see the benefit in implementing it in an application at this development stage. However, I have tried to create an overlay using jQuery but I've scrapped every attempt as I can't seem to make it all come together. My main problem is preventing the submission when the user incorrectly types a password or cancels the overlay. Desired Flow Persistant Login Sensitive Page Submit Password Confirmation Overlay [Continue Submit | (Cancel | Incorrect] I have already created JavaScript code to encrypt the password to be sent in a parameter, but all I need now is a method of controlling the overlay and how best to use Ajax for this purpose. Please ignore the fact that this is a J2EE web application when answering as it is irrelevant really. Thanks in advance, Alasdair

• Codeplex/Sourceforge for internal use

  - by Josh

  I'm looking for a free/open source collaborative project manager that can be deployed internally in my workplace that would act similar to Codeplex or Sourceforge. Does anyone know of something like this, and if so do you have experience with it. Requirements: Open Source or Free Locally Deployable Has the same types of features found in Sourceforge / Codeplex Issue/Feature Tracking Community Interaction (ie. Voting, Roles, etc.) SCM Integration (Optional) .NET/Windows Friendly (Optional) Every business ends up having internal utilities, and domain specific apps that developers create to make life easier. Given the input of the internal developer community they have the potential to become much better (can you say GMail...), and I would simply like to foster such an environment internally by providing an easy place for that interaction to take place. UPDATE: So I like what I am seeing in both Trac and GForge, but both are heavily geared towards UNIX/Subversion environments. I should have specified this, but we are a MS shop from top to bottom. How practical do you think it is going to be to try and use these in a MS .NET environment? Would that be like trying to shove a square peg through a round hole?

• How do I stop the m2eclipse plugin interfering with command line mvn builds?

  - by locka

  I use the m2eclipse plugin in Eclipse so that I can import a Maven project. The plugin reads the pom.xml and sorts out the dependencies in the projects in an Eclipse friendly way so I'm not looking at a sea of broken references and errors. I use Eclipse for code development however I usually build the projects from the command line, e.g. "mvn clean install". Unfortunately when I do this, m2eclipse detects disk activity and attempts to rebuild the workspace. This interferes with the command line build and sometimes results in a race condition. For example the command line might be in its clean phase but fails because it tries to delete a file or directory which is locked during the workspace rebuild. Aside from that workspace rebuilding is incredibly slow, and between failed builds and wasted CPU my build process is 2-3x longer than it should be. It isn't an option to not use Eclipse (e.g. to use Netbeans), or to disable m2eclipse. It is a useful plugin except for this behaviour. So my question is, how do I stop m2eclipse from rebuilding the workspace all the time? Can I invoke a manual refresh and otherwise disable this behaviour?

• Microsoft Solver Foundation constraint

  Hello, I'm trying to use Microsoft Solver Foundation 2 to solve a fairly complicated situation, however I'm stuck with an UnsupportedModelException even when I dumb down the model as much as possible. Does anyone have an idea of what I'm doing wrong? Following is the least example required to reproduce the problematic behavior. var ctx = SolverContext.GetContext(); var model = ctx.CreateModel(); var someConstant = 1337.0; var decisionA = new Decision(Domain.Real, "decisionA"); var decisionB = new Decision(Domain.Real, "decisionB"); var decisionC = new Decision(Domain.Real, "decisionC"); model.AddConstraint("ca", decisionA <= someConstant); model.AddConstraint("cb", decisionB <= someConstant); model.AddConstraint("cc", decisionC <= someConstant); model.AddConstraint("mainConstraint", Model.Equal(Model.Sum(decisionA, decisionB, decisionC), someConstant)) model.AddGoal("myComplicatedGoal", GoalKind.Minimize, decisionC); var solution = ctx.Solve(); solution.GetReport().WriteTo(Console.Out); Console.ReadKey(); Please consider that my actual model should include, once complete, a few constraints in the form of a*a+b*a <= someValue, so if what I'm willing to do ultimately isn't supported, please let me know in advance. If that's the case I'd also appreciate a suggestion of some other solver with a .NET friendly interface that I could use (only well-known commercial packages, please). Thanks in advance

• Problems with "global" exception handlers for unhandled exceptions in multithreaded WPF

  - by JustABill

  I have a program that, among other things, needs to be able to refresh the contents of a directory when the user tells it to. The actual task doesn't really matter, but this is the simplest way of causing this problem to occur that I know of. If I tell it to open a directory that doesn't exist, I get the "unhandled exception" dialog in VS with a stack trace of, from outer to inner: [External code] Textbox PreviewKeyUp event [External code] ClassA's path property being set ClassA's internal path update function being called A call to the INotifyPropertyChanged event [External code] A call to the getter for ClassB's list of children A call to ClassB's internal directory list function And then it fails inside this internal function. I have the following in my App.xaml.cs: private void Application_Startup(object sender, StartupEventArgs e) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Application.Current.Dispatcher.UnhandledException += new System.Windows.Threading.DispatcherUnhandledExceptionEventHandler(Dispatcher_UnhandledException); } But neither of their exception handlers are being called. If I run this program from outside VS, I don't get notified of an exception at all, it just breaks because of the invalid input. And yes, the Application_Startup event is being called. How can I properly "trap" this exception so I can provide a friendly error message and kill the program?

• Enter ID instead of name on submit (form)

  - by Derek

  In my activities table, I have a user ID and a project ID. When a user (of admin level) creates an activity they select from a drop down menu a project. Here is the select query to draw up appropriate values: $sql = "SELECT usersprojects_tb.projectid, projects.projectname FROM projects INNER JOIN usersprojects on projects.projectid = usersprojects.projectid WHERE usersprojects.userid = '".$_SESSION['SESS_USERID']."'"; And for the tag with the dropdown menu, I have this: <?php echo $row['projectname']?> I have tried submitting the form with 'projectid' here instead and the project ID is stored successfully in my activies table. However, the user needs to see the project names (IDs arent exactly user-friendly!) And with 'projectname' as displayed, they can select the names of the available projects (to associate an activity with) but the project ID is not stored, how I link this up, so that when the project name is sent, the ID for this project is stored properly in my activities table. I'm also having the exact same problem with the users drop down. As the admin user selects a user from the drop down to assign the task to. I exactly what I want, but I think I may be using the wrong syntax! Any help is much appreciated. Thanks.
