• GUID.TryParse() ?

  - by Jack Marchetti

  Obviously there is no public GUID.TryParse() in .NET CLR 2.0. So, I was looking into regular expressions [aka googling around to find one] and each time I found one there was a heated argument in the comments section about RegEx A doesn't work, use RegEx B. Then someone would write Regex C yadda yadda So anyway, What I decided to do was this, but I feel bad about it. public static bool IsGuid (string possibleGuid) { try { Guid gid = new Guid(possibleGuid); return true; } catch (Exception ex) { return false; } } Obviously I don't really like this since it's been drilled into me since day one to avoid throwing exceptions if you can defensibly code around it. Does anyonek now why there is no public Guid.TryParse() in the .NET Framework? Does anyone have a real Regular Expression that will work for all GUIDs?

• Regarding Authlogic and page redirection.

  - by Paddy

  I am using authlogic for authentication in my Rails app. Have named routes for the frequent actions, viz: map.login "login", :controller = "user_sessions", :action = "new" map.logout "logout", :controller = "user_sessions", :action = "destroy" map.register "register", :controller = "users", :action = "new" map.edit 'user/edit/:id', :controller = "users", :action = "edit" But also in my routes.rb i have these automatically created REST routes too: map.resources :user_sessions map.resources :users The problem now is that a user can login from two different routes. Ex: From, http://localhost/login and also from http ://localhost/user_sessions/new. How do i restrict access only from the named route i have defined and not allow from user_sessions/new?

Following http://corelib.rubyonrails.org/classes/Time.html#M000240 If I want to add 1 day, it actually adds 60*60*24 days (86,400 days) r=Record.find(:first) =>Sat, 30 Dec 1899 19:00:00 -0600 r.date + (60*60*24) =>Fri, 20 Jul 2136 19:00:00 -0600 But if I do this it actually adds 1 day: t = Time.now =>Mon Jun 14 10:32:51 -0600 2010 t + (60 * 60 * 24) =>Tue Jun 15 10:33:21 -0600 2010 I guess it has to do with the format...how do I make this work?

  - by kranthi

  hi, I am using jquery ajax method on my aspx page,which will invoke the webmethod in the code behind.Currently the webmethod takes a couple of parameters like firstname,lastname,address etc which I am passing from jquery ajax method using data:JSON.stringify({fname:firstname,lname:lastname,city:city}) now my requirement has been changed such that,the number and type of parameters that are going to be passed is not fixed for ex.parameter combination can be something like fname,city or fname,city or city,lname or fname,lname,city or something else.So the webmethod should be such that it should accept any number parameters.I thought of using arrays to do so, as described here.

• cross domain gwt ?

  - by jlo

  is there a way to run gwt on a proxy loaded web page ? ex) using proxy script on myexamplesite.com that loads finance.google.com, and running GWT on the newly loaded page. I've been doing the above before I found about GWT, using LAMP stack + Jquery (UI), which quickly turned out to be crap and inefficient. All this trouble to bypass browser's default Single Origin Policy. So, right now, is it possible to overcome this problem with GWT ? Is it possible to some how, run javascript on a html page from finance.google.com loaded into myexamplesite.com's frame with GWT or other solution? I am not looking to do JSON or RSS related topics. What I need is high lighted in bold. Is GWT + Gears what I should be using ? Thank you.

• How to set up dynamically Part in MultipartRequestEntity

  - by ee_vin

  Hello, I'm using commons-httpclient-3.1 inside my android application. And I would like to know if it possible to manipulate Part (org.apache.commons.httpclient.methods.multipart.Part) dynamically? Essentially adding new FilePart and new StringPart at runtime before sending the request. Every example I've found until now suppose that you know how many fields you are dealing with. Ex: File f = new File("/path/fileToUpload.txt"); PostMethod filePost = new PostMethod("http://host/some_path"); Part[] parts = { new StringPart("param_name", "value"), new FilePart(f.getName(), f) }; filePost.setRequestEntity( new MultipartRequestEntity(parts, filePost.getParams()) ); HttpClient client = new HttpClient(); int status = client.executeMethod(filePost); code from http://hc.apache.org/httpclient-3.x/apidocs/org/apache/commons/httpclient/methods/multipart/MultipartRequestEntity.html Android specific thread: http://groups.google.com/group/android-developers/browse_thread/thread/0f9e17bbaf50c5fc Thank you

• Visual Studio 2010 Macro - Reporting Progress

  - by user295841

  I have just discovered macros in Visual Studio and I can't be happier. Well... I have my complaints but... you know ;) A few of my macros are taking quite a while to complete and I am looking for a way to track progress. I build a log file during most of my macro processes but I have not found a good way to report progress without pausing the process. Ex. MsgBox("Progress") Any way to access the output window or even better the VS status bar?

• Automatically update audit information on Entity

  - by Nix

  I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? Let me know if any more information is needed.

• Custom validatior in ASP.net

  - by DJPB

  Hi there. I'm working on an ASP.NET/C# app. I have 2 text boxes and I need to validate if the input text for both of them are not both null ex: if(string.IsNullOrEmpty(TextBox1.Text) && string.IsNullOrEmpty(TextBox2.Text) ) //FAIL!!! else // OK! that is, at least one txtBox has values I was planning on using a custom validator but it seems that the validation function only gets called when something is written on the textBox i'm using has the 'control to validate'. Now, that doesn't work for me since I want to show an error message when both text boxes are empty. Is there a way to make the validation function to be called with, for example a postback? Or is there any other better approach to this case than the custom validator? tks

• How to add characters to reach the maximum size of a char[].

  - by Bon_chan

  Hi folks, I have the following part of code : for(int i=0;i<n;i++) { printf("Student %d\n",i+1); printf("Enter name : "); scanf("%s",&(student+i)->name); fflush(stdin); lengthName = strlen((student+i)->name); while(lengthName !='\0') { }} when the length is shorter than 10, it will add hyphens until reaching the maximum size. Ex : John = 6 hyphens will be added I know how to do it in csharp but can't figure it out in c. Could some of you give me some lights please? PS : Oh yes the variable name is char name[10+1] and it a part of the structure called student.

• How can a string timestamp with hours 0 to 24 be parsed

  - by user897052

  I am trying to parse a string timestamp of format "yyyyMMddHHmmss" with DateTime.ParseExact(). The catch is I must allow for an hour value of "24" (i.e. hours can be from 0 to 24; Note: I can't control the input values.) and, of course, that results in an exception. Are there any settings/properties I can set instead of manually parsing/using regex's? If not, any efficient parsing ideas? ex. DateTime.ParseExact("20120911240000", "yyyyMMddHHmmss", System.Globalization.CultureInfo.InvariantCulture); hour 24 means hour 0 of next day (so day + 1, hour = 0)

• Creating an Attribute to check for Exceptions

  - by BiffBaffBoff

  I'm creating an attribute so that whenever an exception occurs on my site, I'll receive an email detailing the exception. I've got so far but my Attribute code doesn't seem to fire if an exception occurs: public class ReportingAttribute : FilterAttribute, IExceptionFilter { public void OnException(ExceptionContext filterContext) { // This will generate an email to me ErrorReporting.GenerateEmail(filterContext.Exception); } } Then above my Controller I'm doing: [ReportingAttribute] public class AccountController : Controller The other way to do it is ofcourse putting ErrorReporting.GenerateEmail(ex) inside my catch blocks? There must be a simpler way? Thats why I thought of creating the Attribute to handle this

• initialization of objects in c++

  - by Happy Mittal

  I want to know, in c++, when does the initialization of objects take place? Is it at the compile time or link time? For ex: //file1.cpp extern int i; int j=5; //file2.cpp ( link with file1.cpp) extern j; int i=10; Now, what does compiler do : according to me, it allocates storage for variables. Now I want to know : does it also put initialization value in that storage or is it done at link time?

• Validating IPv4 string in Java

• Writing WCF messages to a text log in configurable directory.

  - by Arsh

  Hello everyone, I have a WCF web service that is deployed at IIS. Part of the web service is to validate the inputs using EntLib 4.1 For ex, the string values can be of specific length and so on. In case of the validation being failed a fault exception is raised and the service is supposed to write the message in log file. How do I go about creating the log file to a location that can be configured from a config file. Basically how do we write messages from IIS (since the service is hosted at IIS, I am assuming that that will be the source !!!!) Regards.

• Microsoft Visual Studio License

  - by Germstorm

  I developed a small winforms application for myself in Microsoft Visual Studio 2008 Professional Edition at my workplace, the Visual Studio is licensed to the firm I work at. If I want to sell that application, what are my license options? EDIT: The issue here is not my relationship with my employer (the code was written after hours, we have an understanding) but my relationship with Microsoft. Ex. if I continue developing in Visual Studio Express can I keep my old code? Is there a way to verify if some assemblies were written using a Visual Studio Professional?

• Android: how to update UI dynamically?

  - by pandre

  I have an Android app and I need to change UI dynamically: ex: when user presses a button, I want to change the current activity's views and, as in some cases there are a lot of views involved, I need to display a ProgressDialog. I have been using an AsyncTask, but I think that it is not the best solution, because AsyncTask's doInBackground runs a different thread, so I can't update UI from there - I have to use runOnUiThread, which runs the code in the UI Thread, but freezes the progress dialog that is shown. I guess there should be more people with similar issues, as updating UI while displaying a ProgressDialog seems to be something done regularly by applications. So does anyone have a solution to this?
