  • VB.NET: Scrollbar "button"?

    - by Omega
    I plan on using a scrollbar for, well, scrolling an image. The image is 200x500, however, the only visible area is 200x250. So I set the max value to 250, and the min value to 0. The idea is that if I drag the scrollbar's button to the bottom, 250 pixels will have moved for the image, right? But wait, the scrollbar's button is.... very small. And the scrollbar is actually pretty long. Is there a way to make the scrollbar's button longer?

    - by user3519124
    :) i have a DAL class file in my project, that my teacher sent me and explained to me but i did not really understand it. It has number of functions, and I understand only few of them, like with connecting to the database or creating a command object but there are 2 that I dont understand: public static DataTable GetTable(string str) { OleDbConnection con = DAL.GetConnection(); OleDbCommand cmd = DAL.GetCommand(con, str); DataTable dt = new DataTable(); OleDbDataAdapter adp = new OleDbDataAdapter(); adp.SelectCommand = cmd; adp.Fill(dt); return dt; } public static int ExecuteNonQuery(string str) { int num = -1; OleDbConnection con = DAL.GetConnection(); con.Open(); if (con.State == ConnectionState.Open) { OleDbCommand cmd = DAL.GetCommand(con, str); num = cmd.ExecuteNonQuery(); con.Close(); } return num; } thank you :)

  • Please Explain .NET Delegates

    - by user275561
    So I read MSDN and Stack Overflow. I understand what the Action Delegate does in general but it is not clicking no matter how many examples I do. In general, the same goes for the idea of delegates. So here is my question. When you have a function like this: public GetCustomers(Action<IEnumerable<Customer>,Exception> callBack) { } What is this, and what should I pass to it?

  • .NET Splash screen issues

    - by CODe
    I have a splash screen for my C# database application that is called via the Shown event. The splash screen contains some information that is preprocessed when the main form's constructor is called, hence why I'm using the Shown event, because that information should be available. However, when the splash screen is shown, the main form is whited out, and the menu bar, bottom menu bar, and even the gray background are all white and invisible. It looks like the program is hanging, but after the 5 second delay I have built in, the banner goes away and the program is shown normally. Also, on the banner, I have labels that are not shown when the splash screen displays... Here is my code, some reasoning behind why it isn't working would help greatly. SPLASH SCREEN CODE : public partial class StartupBanner : Form { public StartupBanner(int missingNum, int expiredNum) { InitializeComponent(); missingLabel.Text = missingNum.ToString() + " MISSING POLICIES"; expiredLabel.Text = expiredNum.ToString() + " EXPIRED POLICIES"; } } CALLING CODE : private void MainForm_Shown(object sender, EventArgs e) { StartupBanner startup = new StartupBanner(missingPoliciesNum, expiredPoliciesNum); startup.MdiParent = this; startup.Show(); Thread.Sleep(5000); startup.Close(); } Using startup.ShowDialog() shows the correct label information on the splash screen, but that locks up the application, and I need the splash to go away after about 5 seconds, which is why it's a splash. ;)

  • vb.net array for slideshow button

    - by StealthRT
    Hey all, i am in the middle of trying to figure out how to go about doing this... I have a form that i call like so: call frmSlideShow.showWhat(1,4,8,9,11,22) Each of the numbers represents a different image slide (slide1.png, slide4.png, etc..). The problem i am having is trying to create a "previous" and "next" button to flip through them all. Trying to figure out what number the user is on and going from there and seeing what numbers are still left from the list above that was sent, etc. If anyone has an idea how i would go about doing that then that would be awesome! :) David

  • ASP.NET MVC Deployed Application Server Address

    - by Jacob Huggart
    I have an application that sends an email to a user so that they may access a web form. In the email there is just a link to the start page of this form. Currently, I have the value for the form location hardcoded. Once the app is deployed I know it is in inetpub/wwwroot/appName, which results in a URL of serverip:appPort/appName. What is the C# to get the serverip:appPort portion of the URL that I need? I think that server.mappath() might work, but for some reason I can't get to the method even though I have the necessary references.

  • Problem with ASP.NET MVC DropDownList not displaying selected value

    - by Jova
    I have an aspx page which allows me to edit articles. Among things I can edit is which category the article belongs to. The category is chosen through a DropDownList as shown here, <%= Html.DropDownList("categoryID", (IEnumerable<SelectListItem>)ViewData["CategoryID"], new { @class = "textbox" }) %> However, the articles category isn't selected when I go to that page. The ViewData I use for the DropDownList looks like this, ViewData["CategoryID"] = new SelectList(categories, "CategoryID", "Title", article.CategoryID); Which should select the article.CategoryID as it's selected value. Have I done this wrong?

  • ASP.NET MVC Patterns

    - by Sam Striano
    Hello, I am fairly new to MVC, but after playing with it (MVC 3/Razor), I am hooked. I have a few questions: 1) What is the best, or most widely used pattern to develop MVC apps in? Repository, DDD, UOW? 2) I am using the Entity Framework 4, so could some please explain to me or point me to a good source that will explain the Repository Pattern w/EF4? Doesn't EF4 take place as the business layer and the data access layer? Does the Repository Pattern even provide a benefit? 3) Also, one last question, could someone explain the whole relationship between the Controller, the Model and the View? I get the basics, but maybe a little more in depth of the correct way to use it. View Models - Say I have a view that displays customer info, and one that edits it, should I have a view model and an edit model, or can the be passed around? 4) Examples?? Thanks for the help up front, $("Sam") ** EDIT ** Am I on the right track here: Public Class HomeController Inherits System.Web.Mvc.Controller Function Index(ByVal id As Integer) As ActionResult Return View(New HomeModel) End Function <HttpPost()> _ Function Index(ByVal Model As HomeModel) As ActionResult Return View(Model) End Function End Class Public Class HomeModel Private _Repository As IRepository(Of Customer) Public Property Customer As Customer Public Sub New() End Sub Public Sub New(ByVal ID As Integer) _Repository = New CustomerRepository Customer = _Repository.GetByID(ID) End Sub End Class Public Interface IRepository(Of T) Function GetByID(ByVal ID As Integer) As T Sub Add(ByVal Entity As T) Sub Delete(ByVal Entity As T) End Interface Public Class CustomerRepository Implements IRepository(Of Customer) Public Sub Add(ByVal Entity As Customer) Implements IRepository(Of Customer).Add End Sub Public Sub Delete(ByVal Entity As Customer) Implements IRepository(Of Customer).Delete End Sub Public Function GetByID(ByVal ID As Integer) As Customer Implements IRepository(Of Customer).GetByID Return New Customer With {.ID = ID, .FirstName = "Sam", .LastName = "Striano"} End Function End Class Public Class Customer Public Property ID As Integer Public Property FirstName As String Public Property LastName As String End Class

  • .NET multithreading, volatile and memory model

    Assume that we have the following code: class Program { static volatile bool flag1; static volatile bool flag2; static volatile int val; static void Main(string[] args) { for (int i = 0; i < 10000 * 10000; i++) { if (i % 500000 == 0) { Console.WriteLine("{0:#,0}",i); } flag1 = false; flag2 = false; val = 0; Parallel.Invoke(A1, A2); if (val == 0) throw new Exception(string.Format("{0:#,0}: {1}, {2}", i, flag1, flag2)); } } static void A1() { flag2 = true; if (flag1) val = 1; } static void A2() { flag1 = true; if (flag2) val = 2; } } } It's fault!

    - by Louise
    I'm adding a ToolTip to a ListViewItem. However, the ToolTip only shows up when the user hovers over the first cell in the row to which the ToolTip has been applied. MyListViewItem.ToolTipText = "Important Message" The only other code I have related to ToolTips is this: MyListView.ShowItemToolTips = True Any idea how I can make the ToolTip show up on a specific cell in a row, or even the entire row?

  • Login time out when calling opening a new window from modal popup (ASP.NET)

    - by Harsh Shah
    I have a weird problem. I have a window, on a button click I open a modal popup (using ModelPopupExtender), that let's you select a few criteria and then click a submit button. On click of submit button, I open a new window (using window.open()) that shows the status of what happened to your submitted request. However, every time this status window is opened, it goes to the login page. I am thinking the modal popup can't pass the authentication cookie to the newly opened window, but I'm not sure. Here's my web.config portion:
