  • LINQ query on a DataTable

    - by Calanus
    I'm trying to perform a LINQ query on a DataTable object and bizarrely I am finding that performing such queries on DataTables is not straightforward. For example: var results = from myRow in myDataTable where results.Field("RowNo") == 1 select results; This is not allowed. Any ideas how to get something like this working? I'm amazed that LINQ queries are not allowed on DataTables!

  • Display new image on web page

    - by RuiT
    Hello, I'm uploading images to a folder and I want to display each new image on a web page every time it is saved in the folder. I can display the initial image, which is already in the folder, and I can also detect when a new image is saved into the folder but I don't know how to display the new images. I'm new to web development. Can somebody help me? Here's the code: public partial class _Default : System.Web.UI.Page { string DirectoryPath = "C:\\Users\\Desktop\\PhotoUpload\\Uploads\\"; protected void Page_Load(object sender, EventArgs e) { FileSystemWatcher watcher = new FileSystemWatcher(); try { watcher.Path = DirectoryPath; watcher.Created += new FileSystemEventHandler(watcher_Created); watcher.EnableRaisingEvents = true; Image image = Image.FromFile(DirectoryPath + "inicial.jpg"); MemoryStream ms = new MemoryStream(); image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); byte[] im = ms.ToArray(); Context.Response.ContentType = "Image/JPG"; Context.Response.BinaryWrite(im); } catch (Exception ex) { } } void watcher_Created(object sender, FileSystemEventArgs e) { Console.WriteLine("File Created: Name: " + e.Name); try { //How to display new image? } catch (Exception ex) { } } }

  • Best solution for exporting Word documents to PDF programatically (without using a "software printer

    - by mbmccormick
    I'm looking for a way to export a Word document as a PDF. I would like to do this without the use of a "software printer" (such as CutePDF, etc.) and stick to reference assemblies if at all possible. I'm using Microsoft Office Interop Assemblies to generate a Word Document which I save to a temporary directory. So its not necessary for this solution to interact directly with Microsoft Office, unless it needs to. Any help or feedback you might have would be greatly appreciated! Thanks!

  • How do I deploy my ASP MVC project to my Win7 system?

    - by MedicineMan
    Hi, I am deploying my first ASP MVC project. The project runs just fine, I would like to take the next step and run this outside of my visual studio environment on my local IIS. I am running Windows7, Visual Studio 2008, and I have created a basic ASP MVC project. On my solution, I find the project I would like to deploy. I right click and select Publish. I have backed up C:\inetpub\wwwroot\ and would like to deploy there. I accept all defaults, and click the "Publish" button. The Output Build window shows 1 project failed. Basically is says that it is unable to add any of the binaries to the site, copy files, create new directories... Access is denied. When I do click "Publish" at work, I don't get these errors. What do I have to do here to publish the website to make the website available to the rest of my home network? Also wwwroot appears to be readonly, but telling the folder to not be read only doesn't seem to help, it still appears to be readonly even after I've unselected this property in the property dialog.

  • Pass Parameter to Subroutine in Codebehind

    - by Sanjubaba
    I'm trying to pass an ID of an activity (RefNum) to a Sub in my codebehind. I know I'm supposed to use parentheses when passing parameters to subroutines and methods, and I've tried a number of ways and keep receiving the following error: BC30203: Identifier expected. I'm hard-coding it on the front-end just to try to get it to pass [ OnDataBound="FillSectorCBList("""WK.002""")" ], but it's obviously wrong. :( Front-end: <asp:DetailsView ID="dvEditActivity" AutoGenerateRows="False" DataKeyNames="RefNum" OnDataBound="dvSectorID_DataBound" OnItemUpdated="dvEditActivity_ItemUpdated" DataSourceID="dsEditActivity" > <Fields> <asp:TemplateField> <ItemTemplate> <br /><span style="color:#0e85c1;font-weight:bold">Sector</span><br /><br /> <asp:CheckBoxList ID="cblistSector" runat="server" DataSourceID="dsGetSectorNames" DataTextField="SectorName" DataValueField="SectorID" OnDataBound="FillSectorCBList("""WK.002""")" ></asp:CheckBoxList> <%-- Datasource to populate cblistSector --%> <asp:SqlDataSource ID="dsGetSectorNames" runat="server" ConnectionString="<%$ ConnectionStrings:dbConn %>" ProviderName="<%$ ConnectionStrings:dbConn.ProviderName %>" SelectCommand="SELECT SectorID, SectorName from Sector ORDER BY SectorID"></asp:SqlDataSource> </ItemTemplate> </asp:TemplateField> </Fields> </asp:DetailsView> Code-behind: Sub FillSectorCBList(ByVal RefNum As String, ByVal sender As Object, ByVal e As System.EventArgs) Dim SectorIDs As New ListItem Dim myConnection As String = ConfigurationManager.ConnectionStrings("dbConn").ConnectionString() Dim objConn As New SqlConnection(myConnection) Dim strSQL As String = "SELECT DISTINCT A.RefNum, AS1.SectorID, S.SectorName FROM Activity A LEFT OUTER JOIN Activity_Sector AS1 ON AS1.RefNum = A.RefNum LEFT OUTER JOIN Sector S ON AS1.SectorID = S.SectorID WHERE A.RefNum = @RefNum ORDER BY A.RefNum" Dim objCommand As New SqlCommand(strSQL, objConn) objCommand.Parameters.AddWithValue("RefNum", RefNum) Dim ad As New SqlDataAdapter(objCommand) Try [Code] Finally [Code] End Try objCommand.Connection.Close() objCommand.Dispose() objConn.Close() End Sub Any advice would be great. I'm not sure if I even have the right approach. Thank you!

  • What's the reason both Image and Bitmap classes don't implement a custom equality/hashcode logic?

    - by devoured elysium
    From MSDN documentation, it seems as both GetHashCode() and Equals() haven't been overriden in Bitmap. Neither have them been overriden in Image. So both classes are using the Object's version of them just compares references. I wasn't too convinced so I decided to fire up Reflector to check it out. It seems MSDN is correct in that matter. So, is there any special reason why MS guys wouldn't implement "comparison logic", at least for the Bitmap class? I find it is kinda acceptable for Image, as it is an abstract class, but not so much for the Bitmap class. I can see in a lot of situations calculating the hash code can be an expensive operation, but it'd be alright if it used some kind of lazy evaluation (storing the computed hash code integer in a variable a variable, so it wouldn't have to calculate it later again). When wanting to compare 2 bitmaps, will I have to resort to having to run all over the picture comparing each one of its pixels? Thanks

  • Why would a error get thrown inside my try-catch?

    - by George Johnston
    I'm pushing a copy of our application over to a new dev server (IIS7) and the application is blowing up on a line inside of a try-catch block. It doesn't happen locally, it actually obey's the rules of a try-catch block, go figure. Any idea why this would be happening? Shouldn't it just be failing silently? Is there something environmental I need to enable/disable? Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Line 229: Try Line 230: Here >> : _MemoryStream.Seek(6 * StartOffset, 0) Line 232: _MemoryStream.Read(_Buffer, 0, 6) Line 233: Catch ex As IOException End Try Although it doesn't matter for answering this question, I thought I would mention that it's third party code for the Geo IP lookup.

  • How can I dynamically clear all controls in a user control?

    - by Michael
    Is it possible to dynamically (and generically) clear the state of all of a user control's child controls? (e.g., all of its TextBoxes, DropDrownLists, RadioButtons, DataGrids, Repeaters, etc -- basically anything that has ViewState) I'm trying to avoid doing something like this: foreach (Control c in myUserControl.Controls) { if (c is TextBox) { TextBox tb = (TextBox)c; tb.Text = ""; } else if (c is DropDownList) { DropDownList ddl = (DropDownList)c; ddl.SelectedIndex = -1; } else if (c is DataGrid) { DataGrid dg = (DataGrid)c; dg.Controls.Clear(); } // etc. } I'm looking for something like this: foreach (Control c in myUserControl.Controls) c.Clear(); ...but obviously that doesn't exist. Is there any easy way to accomplish this dynamically/generically?

  • How can I get System.Type from "System.Drawing.Color" string

    I have an xml stored property of some control <Prop Name="ForeColor" Type="System.Drawing.Color" Value="-16777216" /> I want to convert it back as others System.Type type = System.Type.GetType(propertyTypeString); object propertyObj = TypeDescriptor.GetConverter(type).ConvertFromString(propertyValueString); System.Type.GetType("System.Drawing.Color") returns null. The question is how one can correctly get color type from string (it will be better not to do a special case just for Color properties) Update from time to time this xml will be edited by hand

  • ModelState always valid

    - by Jaimal Chohan
    I've got something seemingly very simple not working. I have got a model public class Name: Entity { [StringLength(10), Required] public virtual string Title { get; set; } } public class Customer: Entity { public virtual Name Name { get; set; } } a view model public class CustomerViweModel { public Customer Customer { get; set; } } a view <% using(Html.BeginForm()) { %> <%= Html.LabelFor(m => m.Customer.Name.Title)%> <button type="submit">Submit</button> <% } %> and a controller [HttpPost] public ActionResult Index([Bind(Prefix = "Customer")] Customer customer) { if(ModelState.IsValid) Save else return View(); } No matter what I enter as the title (null, or a string 10 chars), ModelState.IsValid is always true. The Title field in the Customer object has a value, so the data is being passed around, but not being validated? Any clues?

  • Bind Data to Multiple Labels From Multiple DataSources

    - by Steven
    I have two AccessDataSources each returning one row. I want to use the data in each row to populate content on my page, so I figured I would use a Repeater or FormView. However, I would not necessarily want the labels bound to a particular DataSource placed together. For example, I might want labels from the following columns in order (DataSourceName.ColumnName): TestSetup.TestType, TestSummary.FormattedValue, TestSetup.DeviceChannel, TestSummary.CompletedOn. How do I handle this? Do I just have a separate Repeater/FormView for each value? Can I have both Repeater's/FormView's in 'scope' at the same time? Note: No language preference (C#/VB).

  • What are the benefits of using WCF?

    - by sontek
    We currently just utilize soap webservices for all our communication but have been thinking about moving to WCF instead. What are the benefits of using it over an asmx service? If we do go with a WCF service, can other languages still communicate with it? SOAP is standardized and all languages can interact with it. Are there any really good examples of how to get started with WCF that show the benefits of it over soap? EDIT I just found this question which is quite helpful. The Getting Started Tutorial is great.

  • Why always fires OnFailure when return View() to Ajax Form ?

    - by Wahid Bitar
    I'm trying to make a log-in log-off with Ajax supported. I made some logic in my controller to sign the user in and then return simple partial containing welcome message and log-Off ActionLink my Action method looks like this : public ActionResult LogOn(LogOnModel model, string returnUrl) { if (ModelState.IsValid) { if (MembershipService.ValidateUser(model.UserName, model.Password)) { FormsService.SignIn(model.UserName, model.RememberMe); if (Request.IsAjaxRequest()) { //HERE IS THE PROBLEM :( return View("LogedInForm"); } else { if (!String.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } else { ModelState.AddModelError("", "The user name or password provided is incorrect."); if (Request.IsAjaxRequest()) { return Content("There were an error !"); } } } return View(model); } and I'm trying to return this simple partial : Welcome <b><%= Html.Encode(Model.UserName)%></b>! <%= Html.ActionLink("Log Off", "LogOff", "Account") %> and of-course the two partial are strongly-typed to LogOnModel. But if i returned View("PartialName") i always get OnFailure with status code 500. While if i returned Content("My Message") everything is going right. so please tell me why i always get this "StatusCode = 500" ??. where is the big mistake ??. By the way in my Site MasterPage i rendered partial to show long-on simple form this partial looks like this : <script type="text/javascript"> function ShowErrorMessage(ajaxContext) { var response = ajaxContext.get_response(); var statusCode = response.get_statusCode(); alert("Sorry, the request failed with status code " + statusCode); } function ShowSuccessMessage() { alert("Hey everything is OK!"); } </script> <div id="logedInDiv"> </div> <% using (Ajax.BeginForm("LogOn", "Account", new AjaxOptions { UpdateTargetId = "logedInDiv", InsertionMode = InsertionMode.Replace, OnSuccess = "ShowSuccessMessage", OnFailure = "ShowErrorMessage" })) { %> <%= Html.TextBoxFor(m => m.UserName)%> <%= Html.PasswordFor(m => m.Password)%> <%= Html.CheckBoxFor(m => m.RememberMe)%> <input type="submit" value="Log On" /> < <% } %>

  • How does MVC ViewData work?

    - by Matt
    I am toying around with an MVC application just to learn the technology. I am mocking up a check register application that keeps track of a checking account, what has cleared the bank and what has not. I am using EF for my model and everything seems to be working correctly insofar as Edit, Create, etc. However, I have a couple of totals at the top. One to show the bank's balance and another to show the actual balance. It works most of the time but when I do Edit's it does not always accurately reflect the new total and I need it to update everytime a change is made (i.e when something clears the bank): [Authorize(Roles = "admin, checkUser")] public ActionResult Index() { var resultSet = from myChecking in chk.tblCheckings orderby myChecking.id descending select myChecking; ViewData.Model = resultSet.Take(45).ToList(); //for balances var actualBalance = from theChecking in chk.tblCheckings select theChecking.deposit - theChecking.withdrawal; var bankBalance = from theChecking in chk.tblCheckings where theChecking.cleared == true select theChecking.deposit - theChecking.withdrawal; //get bank balance ViewData["bankBalance"] = bankBalance.Sum(); //get actual balance ViewData["actualBalance"] = actualBalance.Sum(); return View(); } I am showing the actual and other balance in the Index view as follows: <td colspan="9" style="text-align: center; font-size: 11pt; color: white;"> <%= string.Format("Bank Balance: {0:c}", ViewData["bankBalance"]) %> ------ <%= string.Format("Actual Balance: {0:c}", ViewData["actualBalance"]) %> </td>
