If I click Cntrl+Alt+E, I get an exceptions window, how can I use it in this situation, seems like some exception is not being caught here. Also what other debugging aids can I use here in Visual Studio 2010?

  • Efficiently Combine MatchCollections in .Net Regex

    - by Laramie
    In the simplified example, there are 2 Regular Expressions, one case sensitive, the other not. The idea would be to efficiently create an IEnumerable collection (see "combined" below) combining the results. string test = "abcABC"; string regex = "(?<grpa>a)|(?<grpb>b)|(?<grpc>c)]"; Regex regNoCase = new Regex(regex, RegexOptions.IgnoreCase); Regex regCase = new Regex(regex); MatchCollection matchNoCase = regNoCase.Matches(test); MatchCollection matchCase = regCase.Matches(test); //Combine matchNoCase and matchCase into an IEnumerable IEnumerable<Match> combined= null; foreach (Match match in combined) { //Use the Index and (successful) Groups properties //of the match in another operation } In practice, the MatchCollections might contain thousands of results and be run frequently using long dynamically created REGEXes, so I'd like to shy away from copying the results to arrays, etc. I am still learning LINQ and am fuzzy on how to go about combining these or what the performance hits to an already sluggish process will be.

  • Upload Image with Django Model Form

    - by jmitchel3
    I'm having difficulty uploading the following model with model form. I can upload fine in the admin but that's not all that useful for a project that limits admin access. #Models.py class Profile(models.Model): name = models.CharField(max_length=128) user = models.ForeignKey(User) profile_pic = models.ImageField(upload_to='img/profile/%Y/%m/') #views.py def create_profile(request): try: profile = Profile.objects.get(user=request.user) except: pass form = CreateProfileForm(request.POST or None, instance=profile) if form.is_valid(): new = form.save(commit=False) new.user = request.user new.save() return render_to_response('profile.html', locals(), context_instance=RequestContext(request)) #Profile.html <form enctype="multipart/form-data" method="post">{% csrf_token %} <tr><td>{{ form.as_p }}</td></tr> <tr><td><button type="submit" class="btn">Submit</button></td></tr> </form> Note: All the other data in the form saves perfectly well, the photo does not upload at all. Thank you for your help!

  • How get file names using OpenFileDialog in .NET (1000+ file multiselect)

    - by Cole
    Maybe some of you have come across this before.... I am opening files for parsing. I'm using OpenFileDialog, of course, but i'm limited to a buffer of 2048 on the .FileNames string. Thus, I can only select a few hundred files. This is OK for most cases. However, fore example, I have in one case 1400 files to open. Do you know a way to do this with the open file dialog. I just want the string array of .FileNames, I pass that to parser class. I was also thinking of offering a FolderBrowserDialog option and then I'd use some other method to just loop through all the files in a directory, like the DirectoryInfo class. I'd do this as a last resort if I can't have an all in one solution.

    - by Pinu
    I have a page where a product appears on the right side and the user can add comment so i have a user control which gets all the comments and a small text area where user can add new comment for that product. the link of the page is like http://localhost/Product/TestComment/1 Where 1 indicates the id of the product and I have been hard coding my AddNote function below and fourth argument you see has been hard coded, but i need to pass that as the id of the product. How do i do this AddNote(HttpContext.User.Identity.ToString(), txtComment, 1, DateTime.Now, true); [AcceptVerbs(HttpVerbs.Post)] public ActionResult AddComment(string txtComment) { bool rst = _NotesService.AddNote(HttpContext.User.Identity.ToString(), txtComment, 1, DateTime.Now, true); return RedirectToAction("TestComment"); }

  • .NET 3.5: Dynamically adding classes without recompiling

    - by Nir
    I'd like to build an infrastructure that will monitor a server and check ping, response time, and more. The catch is that future checks (for example: does a certain file exist) will be added without recompiling the infrastructure. How do I build it in such a way that will enable me to attach inherited classes with different functionality, and execute them without recompiling? Thanks!

  • Select All CheckBoxes in GridView ASP.NET using JQuery

    - by dexter
    I have checkBoxes in my Gridview templete columns called "Category A" and "Category B". I want Select-All functionality, i.e. when the user checks the Select-All check Box in category A column, all the checkboxes must get checked under that column. Same for Category B. I am trying with the code below. The problem with my code is, it selects all the check boxes in the entire gridview, "Category A" as well as "Category B"s checkboxes. But, I want only checkboxes selected under the same column. function SelectAllCheckboxesA(chk) { $('#<%=gvSurveys.ClientID %>').find("input:checkbox").each(function() { if (this != chk) { if ($(this).hasClass('CatA') != false) { this.checked = chk.checked; } } else { alert($(this)); } }); } <asp:GridView ID="gvSurveys" runat="server" AutoGenerateColumns="false" AllowSorting="True" Width="1500px"> <Columns> <asp:TemplateField> <HeaderTemplate>Category A <asp:CheckBox ID="chkSelectAllCatA" runat="server" Visible="false" onclick="javascript:SelectAllCheckboxesA(this);" CssClass="SACatA" /> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="chkCatA" runat="server" Enabled="false" CssClass="CatA" /> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <HeaderTemplate> Category B <asp:CheckBox ID="chkSelectAllCatB" runat="server" Visible="false" CssClass="CatB" onclick="javascript:SelectAllCheckboxesB(this);" /> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="chkCatB" runat="server" Enabled="false" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView>

  • How to prevent a javascript/backbone.js cloned model from sharing attributes

    - by user540727
    I'm working with backbone.js models, so I don't know if my question is particular to the way backbone handles cloning or if it applies to javascript in general. Basically, I need to clone a model which has an attribute property assigned an object. The problem is that when I update the parent or clone's attribute, the other model is also updated. Here is a quick example: var A = Backbone.Model.extend({}); var a = new A({'test': {'some': 'crap'}}); var b = a.clone(); a.get('test')['some'] = 'thing'; // I could also use a.set() to set the attribute with the same result console.log(JSON.stringify(a)) console.log(JSON.stringify(b)) which logs the following: {"test":{"some":"thing"}} {"test":{"some":"thing"}} I would prefer to clone a such that b won't be referencing any of its attributes. Any help would be appreciated.

  • Displaying Many-To-Many Database relationship in VB.NET 2008 with DataGrid, MS SQL 2008

    - by user337501
    Computer bombed while posting this, couldnt find a duplicate question but if there is one, forgive me. So, I've run into a wall. And rather than use a ladder to avoid it, I'd like go through it. I'm setting up what I can best describe as a many-to-many relationship in a database. To examplify, imagine I have three primary tables: Items, Categories, Sections(nevermind the potential redundancy) Then I have another table, Properties. Items, Categories, and Sections can be associated with many properties. A single property can be associated with one, all, or none of the other tables. The best way I can figure to do this is to have join tables make the relationship. i.e. tblItems----(Foreign Key)----tblItems_To_Properties----(Foreign Key)----tblProperties In this example, tblItems simply has an "ItemID" Primary Key. tblItems_To_Properties has its own Primary Key(tblItems_To_PropertiesID), a Foreign Key to the Item(ItemID) and a Foreign key to the Property(PropertyID). The Properties table simply has its primary key(PropertyID) I hope this example isnt too confusing...if I have to I can find a way to put a diagram up or something. My problem is, I want to display this in a DataGrid using the Master-Detail method(DevExpress GridControl). I use the tblItems as a test, and I can see the Items in the parent view, but in the child view I see(understandably) the join table and that is it. My goal is to make it so the Grid ignores the join table and shows the Properties table as the only child. Any help on this method or insight into another solution would be muuuuuuuch appreciat

  • ASP.NET MVC unit test controller with HttpContext

    - by user299592
    I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Current.Session. Everytime I create a new instance of my controller is calls the basecontroller constructor and the test fails with a null pointer exception on the HttpContext.Current.Session. Here is the code: public class BaseController : Controller { protected BaseController() { ViewData["UserID"] = HttpContext.Current.Session["UserID"]; } } public class IndexController : BaseController { public ActionResult Index() { return View("Index.aspx"); } } [TestMethod] public void Retrieve_IndexTest() { // Arrange const string expectedViewName = "Index"; IndexController controller = new IndexController(); // Act var result = controller.Index() as ViewResult; // Assert Assert.IsNotNull(result, "Should have returned a ViewResult"); Assert.AreEqual(expectedViewName, result.ViewName, "View name should have been {0}", expectedViewName); } Any ideas on how to mock the Session that is accessed in the base controller so the test in the descendant controller will run?

  • URLRewriter.net fails relative paths when using more than one substring in URL

    - by Andreas Strandfelt
    Hi. I have installed the URLRewriter on my server, and it works fine, but I have a rather big problem. Relative links in hyperlinks, CSS-links, images etc. doesn't work when I have URLs with more than one substring. E.g. (sorry, no http:// in front, as I do not have enough reputation): dkbyg.strandweb.dk/Leje-og-udlejning-arbejdskraft leads to the path dkbyg.strandweb.dk/Workers.aspx and works just fine. But dkbyg.strandweb.dk/Leje-og-udlejning-arbejdskraft/Midtjylland leads to dkbyg.strandweb.dk/Workers.aspx?Region=Midtjylland using this line in the Web.config: <rewrite url="~/Leje-og-udlejning-arbejdskraft/(.+)" to="~/Workers.aspx?Region=$1"/> It rewrites just fine, but my relative links doesn't work anymore. CSS, Images, links and so on thinks my root is now http://dkbyg.strandweb.dk/Leje-og-udlejning-arbejdskraft, which of course doesn't exist. Can't this be fixed? All my links are correctly set using the ~/, like this: <asp:HyperLink ID="HyperLink3" CssClass="black_text" NavigateUrl="~/Forgot-Password" runat="server">I have forgotten my password</asp:HyperLink>

  • .net OpenFileDialog changing the CurrentDirectory

    - by meowing
    Hi, I am using OpenFileDialog. But using it changes the Environment.CurrentDirectory. Using the RestoreDirectory property solves this issue, but I'm using external dlls that I can't control that don't use RestoreDirectory. Is there a way to make it true as default? Or is there any other solution to this annoying problem? Thanks.

  • .NET Working with Locking and Threads

    - by aherrick
    Work on this small test application to learn threading/locking. I have the following code, I would think that the line should only write to console once. However it doesn't seem to be working as expected. Any thoughts on why? What I'm trying to do is add this Lot object to a List, then if any other threads try and hit that list, it would block. Am i completely misusing lock here? class Program { static void Main(string[] args) { int threadCount = 10; //spin up x number of test threads Thread[] threads = new Thread[threadCount]; Work w = new Work(); for (int i = 0; i < threadCount; i++) { threads[i] = new Thread(new ThreadStart(w.DoWork)); } for (int i = 0; i < threadCount; i++) { threads[i].Start(); } // don't let the console close Console.ReadLine(); } } public class Work { List<Lot> lots = new List<Lot>(); private static readonly object thisLock = new object(); public void DoWork() { Lot lot = new Lot() { LotID = 1, LotNumber = "100" }; LockLot(lot); } private void LockLot(Lot lot) { // i would think that "Lot has been added" should only print once? lock (thisLock) { if(!lots.Contains(lot)) { lots.Add(lot); Console.WriteLine("Lot has been added"); } } } }
