  • Usehttpget for script methods in config of asp.net web services

    - by Ajay
    Is there a way to put the usehttpget true/false option for scriptmethods in web.config? I see that even the scriptmethod annotations are placed inline with the code. Is there a way to move this to config as well? Ive seen usehttpget/post option in web.config for webservices but I need the same thing applicable for scriptservices.

  • .NET template class instance - passing a variable data type

    - by FerretallicA
    As the title suggests, I'm tyring to pass a variable data type to a template class. Something like this: frmExample = New LookupForm(Of Models.MyClass) 'Works fine Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine frmExample = New LookupForm(Of SelectedType) 'Ba-bow! frmExample = New LookupForm(Of InstanceOfMyClass.GetType()) 'Ba-bow! LookupForm<Models.MyClass> frmExample; Type SelectedType = InstanceOfMyClass.GetType(); frmExample = new LookupForm<SelectedType.GetType()>(); //Ba-bow frmExample = new LookupForm<(Type)SelectedType>(); //Ba-bow I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either. (How) can I create an instance of a dynamically typed repository at runtime?

  • .NET RegEx - First N chars of First M lines

    - by George
    Hello! I want 4 general RegEx expressions for the following 4 basic cases: Up to A chars starting after B chars from start of line on up to C lines starting after D lines from start of file Up to A chars starting after B chars from start of line on up to C lines occurring before D lines from end of file Up to A chars starting before B chars from end of line on up to C lines starting after D lines from start of file Up to A chars starting before B chars from end of line on up to C lines starting before D lines from end of file These would allow to select arbitrary text blocks anywhere in the file. So far I have managed to come up with cases that only work for lines and chars separately: (?<=(?m:^[^\r]{N}))[^\r]{1,M} = UP TO M chars OF EVERY LINE, AFTER FIRST N chars [^\r]{1,M}(?=(?m:.{N}\r$)) = UP TO M chars OF EVERY LINE, BEFORE LAST N chars The above 2 expressions are for chars, and they return MANY matches (one for each line). (?<=(\A([^\r]*\r\n){N}))(?m:\n*[^\r]*\r$){1,M} = UP TO M lines AFTER FIRST N lines (((?=\r?)\n[^\r]*\r)|((?=\r?)\n[^\r]+\r?)){1,M}(?=((\n[^\r]*\r)|(\n[^\r]+\r?)){N}\Z) = UP TO M lines BEFORE LAST N lines from end These 2 expressions are equivalents for the lines, but they always return just ONE match. The task is to combine these expressions to allow for scenarios 1-4. Anyone can help? Note that the case in the title of the question, is just a subclass of scenario #1, where both B = 0 and D = 0. EXAMPLE: SOURCE: line1 blah 1 line2 blah 2 line3 blah 3 line4 blah 4 line5 blah 5 line6 blah 6 DESIRED RESULT: Characters 3-6 of lines 3-5: A total of 3 matches: <match>ne3 </match> <match>ne4 </match> <match>ne5 </match>

  • Validation with State Pattern for Multi-Page Forms in ASP.NET

    - by philrabin
    I'm trying to implement the state pattern for a multi-page registration form. The data on each page will be accumulated and stored in a session object. Should validation (including service layer calls to the DB) occur on the page level or inside each state class? In other words, should the concrete implementation of IState be concerned with the validation or should it be given a fully populated and valid object? See "EmptyFormState" class below: namespace Example { public class Registrar { private readonly IState formEmptyState; private readonly IState baseInformationComplete; public RegistrarSessionData RegistrarSessionData { get; set;} public Registrar() { RegistrarSessionData = new RegistrarSessionData(); formEmptyState = new EmptyFormState(this); baseInformationComplete = new BasicInfoCompleteState(this); State = formEmptyState; } public IState State { get; set; } public void SubmitData(RegistrarSessionData data) { State.SubmitData(data); } public void ProceedToNextStep() { State.ProceedToNextStep(); } } //actual data stored in the session //to be populated by page public class RegistrarSessionData { public string FirstName { get; set; } public string LastName { get; set; } //will include values of all 4 forms } //State Interface public interface IState { void SubmitData(RegistrarSessionData data); void ProceedToNextStep(); } //Concrete implementation of IState //Beginning state - no data public class EmptyFormState : IState { private readonly Registrar registrar; public EmptyFormState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //Should Validation occur here? //Should each state object contain a validation class? (IValidator ?) //Should this throw an exception? } public void ProceedToNextStep() { registrar.State = new BasicInfoCompleteState(registrar); } } //Next step, will have 4 in total public class BasicInfoCompleteState : IState { private readonly Registrar registrar; public BasicInfoCompleteState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //etc } public void ProceedToNextStep() { //etc } } }

  • ArgumentOutOfRangeException at MySql execution. (MySqlConnector .NET)

    - by Lazlo
    I am getting this exception from a MySqlCommand.ExecuteNonQuery(): Index and length must refer to a location within the string. Parameter name: length The command text is as follows: INSERT INTO accounts (username, password, salt, pin, banned, staff, logged_in, points_a, points_b, points_c, birthday) VALUES ('adminb', 'aea785fbcac7f870769d30226ad55b1aab850fb0979ee00481a87bc846744a646a649d30bca5474b59e4292095c74fa47ae6b9b3a856beef332ff873474cc0d3', 'cb162ef55ff7c58c7cb9f2a580928679', '', '0, '0', '0', '0', '0', '0', '2010-04-18') Sorry for the long string, it is a SHA512 hash. I tried manually adding this data in the table from MySQL GUI tools, and it worked perfectly. I see no "out of range" problem in these strings. Does anybody see something wrong?

  • ASP.NET-MVC2 Preview 1: Are There Any Breaking Changes?

    - by Jim G.
    I was following Steven Sanderson's 'Pro ASP.NET MVC Framework' book. On page 132, in accordance with the author's recommendation, I downloaded the ASP.NET MVC Futures assembly, and added it to my MVC project. Then, without encouragement from the author, I downloaded, installed, and incorporated the ASP.NET MVC2 Preview 1 dlls into my project. Now, I can no longer load the website. That is, when I hit F5 in Visual Studio, I get this error. In retrospect, I think it was a really bad idea to assume that ASP.NET MVC2 Preview 1 would only be additive; but I'd like other people to weigh in. Has anyone noticed any breaking changes in ASP.NET MVC 2 Preview 1? Also - Has anyone noticed any changes that impact Castle Windsor? Also, please let me know if I should be mindful of IIS6 vs. IIS7 ramifications.

  • ASP.NET - Overriding Gridview OnRowCreated to add sort images -- columns are null

    - by Zach
    I'm overriding the onrowcreated to add sort images to the header row of a gridview. This works, but actually adding a sortexpression doesn't. What I want to do is set the images as imagebuttons and set their commandarguments to the sort expression of the column they are sorting for. I would assume I could get the cell and from it's index get the gridviewcolumn. Then, I could just get the sortexpression of the gridview column, but this does not work. The columns are null. OnRowCreated Code snippet below: //if this is the header row, we add sort images to each cell if (row.RowType == DataControlRowType.Header) { //iterate through the cells for (int i = 0; i < row.Cells.Count; i++) { //if the column is sortable and visible if (this.Columns[i].SortExpression != string.Empty && this.Columns[i].Visible) { string strSort = this.Columns[i].SortExpression; } } } Can we not get columns in OnRowCreated like this?

  • A very weird problem with texbox control in .net

    - by Kazoom
    Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

  • ASP.Net AJAX controls, adding via .ashx page

    - by Matt Dawdy
    Okay, this is a continuation of a previous question of mine, but it is distinct enough to be its own question. Based on user interaction, I'm calling a .ashx handler via a jquery ajax call, and that handler is building some html for me that includes some Telerik controls like a masked textbox (masked for a phone number like "(###) ###-####". I got around all the hurdles of using Render() to get the html output of a server control even when it doesn't have a "Page" object or a ScriptHandler object. However, when I show the control to a user, I see the mask in the text of the textbox, but the mask doesn't "work" in the sense that when a user starts typing, it is as if the mask is really just text. So, my question is, after putting the html code out for a masked textbox, how do I tell whatever javascript is supposed to mask the input to really start masking on that specific control? I really hope this made sense. Please tell me if you need any clarification.

  • ASP.Net HttpModule List<> content

    - by test
    We have created an http module that loads data on initialize into a list, and uses that list on every endrequest event of application. However we got a null reference exception on the module at endRequest event complaining that the content is null. Yet we are sure that at module initialization we have put non-null objects correctly. How is this possible? Any ideas? Thanks in advance. The place where i fill the data into the list what named as "Pages" : using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { LandingPageDetails details = new LandingPageDetails(); details.DomainId = Convert.ToInt32(reader["DomainId"]); details.PageId = Convert.ToInt32(reader["TrackingPageId"]); details.PageAddress = Convert.ToString(reader["PageAddress"]); if (!string.IsNullOrEmpty(details.PageAddress)) { Pages.Add(details); } } } // Find the related record on EndRequesst event LandingPageDetails result = Pages.Find ( delegate(LandingPageDetails current) { return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); } ); The line what we get the error return current.PageAddress.Equals(url, StringComparison.InvariantCultureIgnoreCase); "current" is the null object P.S : It works properly, but one day later contents become null. Possibly, there is something wrong on IIS. Our server is Windows 2003, IIS 6.0

  • add on click event to picturebox vb.net

    - by Matt Facer
    I have a flowLayoutPanel which I am programatically adding new panelLayouts to. Each panelLayout has a pictureBox within it. It's all working nicely, but I need to detect when that picture box is clicked on. How do I add an event to the picture? I seem to only be able to find c# examples.... my code to add the image is as follows... ' add pic to the little panel container Dim pic As New PictureBox() pic.Size = New Size(cover_width, cover_height) pic.Location = New Point(10, 0) pic.Image = Image.FromFile("c:/test.jpg") panel.Controls.Add(pic) 'add pic and other labels (hidden in this example) to the big panel flow albumFlow.Controls.Add(panel) So I assume somewhere when I'm creating the image I add an onclick event. I need to get the index for it also if that is possible! Thanks for any help!

  • performance of large number calculations in python (python 2.7.3 and .net 4.0)

    - by g36
    There is a lot of general questions about python performance in comparison to other languages. I've got more specific example: There are two simple functions wrote in python an c#, both checking if int number is prime. python: import time def is_prime(n): num =n/2 while num >1: if n % num ==0: return 0 num-=1 return 1 start = time.clock() probably_prime = is_prime(2147483629) elapsed = (time.clock() - start) print 'time : '+str(elapsed) and C#: using System.Diagnostics; public static bool IsPrime(int n) { int num = n/2; while(num >1) { if(n%num ==0) { return false; } num-=1; } return true; } Stopwatch sw = new Stopwatch(); sw.Start(); bool result = Functions.IsPrime(2147483629); sw.Stop(); Console.WriteLine("time: {0}", sw.Elapsed); And times ( which are surprise for me as a begginer in python:)): Python: 121s; c#: 6s Could You explain where does this big diffrence come from ?

  • DataAnnotations in ASP.NET MVC 2 - Stop MVC from applying RequiredAttribute to Non-nullable DateTime

    - by jwwishart
    Im trying to create a custom version of the RequiredAttribute to replace the built in one and I've got it working for properties that have strings values, but with properties that are DateTime or integer for example, the default RequiredAttribute seems to be applied automatically (IF the property is not nullable!) My problem is that i want to be able to specify a DateTime property as required using my custom required validator which gets the error message from a resources file (I don't want to have to tell the RequiredAttribute the type of the resource file and the key every time i apply it. That is why I'm making a custom one.) How can i prevent the framework from applying the required attribute to properties of type DateTime and int etc without changing them to nullable. Thanks

  • Using ASP.NET Redirect without string URL?

    - by David Dietrich
    For instance, what I have right now is the following: Page.Response.Redirect("Default.aspx", false); Needing to hardcode the string just seems odd to me. The Default.aspx page is already in my project. So is there a way to do the redirect something like the following: Page.Response.Redirect(Default.aspx, false); Where Default.aspx is just the web form. I'd think that this way it would be obvious if there was a problem such as you deleted the web form but didn't update the redirects. Is this possible? Or is there another way entirely I should be looking at this? I suppose I could do something with a static property on the class, but I am wondering if there is a built in thing for this?

  • DateTime from Javascript post to Controller in ASP.NET results in null (01/01/0001)

    - by Geoffrey
    This is driving me crazy, similar to this. If I use a standard form and no javascript the controller correctly binds the datetime. However when I'm posting from a form it always binds as null: "MyObject.Name": "Test name", "MyObject.Date": "5/1/2001" I've tried a couple of variations, 5-1-2001, etc. but cannot seem to get it to take. I can confirm that it is being passed to the server as it shows up in the Request.Form string. My culture is Gregorian and I've set: Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture; In Application_BeginRequest(). What gives?
