  • Using Client Application Services in windows forms not working

    - by Nickson
    i am trying to implement asp.net membership, profile and role based security in a windows application by configuring client Application Services for my windows forms application. I have followed both these articles http://www.dotnetbips.com/articles/e863aa3c-0dd6-468d-bd35-120a334c5030.aspx and http://msdn.microsoft.com/en-us/library/bb546195.aspx step-by-step but for some reason i can't get the authentication working. I have a deployed intranet asp.net website which is already using an asp.net membership database for authentication and want to use that same database for authenitcation in my windows forms application. The site URL is http://myServer_Name:My_Port and i am specifying that URL as the both the Authentication service location and Roles service location in the windows application services property tab. But in the windows application login form, when i say Dim msg As String = "Welcome " If Not Membership.ValidateUser(UsernameTextBox.Text), PasswordTextBox.Text)) Then MessageBox.Show("Invalid User ID or Password!") Else msg = msg + UsernameTextBox.Text End If i get my "Invalid User ID or Password!" message even when i supply a valid user name with the corresponding password. i am able to login with the same credentials from the asp.net site. How can i test if the Authentication service location is being reached from the windows application?? Or what other information can i provide here such that one is able to help me get this working??

  • Need to get back form controls' information externally

    - by Tom
    Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

  • Double confirmation on exit

    - by Sean
    I am trying to make it so that the user is prompted to confirm exiting my program in c#, but for some reason, if they say "yes" they would like to exit, the confirmation box would pop up again. I can't figure out why. if (MessageBox.Show("Are you sure you want to exit?", "Confirm exit", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No) { e.Cancel = true; } else { Application.Exit(); }

  • How to display static (shared) object's properties via a Forms PropertyGrid?

    - by Paul Sasik
    I would like to display static (shared) objects at runtime in a PropertyGrid but if I try to set the selected object property of the grid like this: _propertyGrid.SelectedObject = System.Windows.Forms.Application I get this compilation error: 'Application' is a type and cannot be used as an expression. Is there a way to display a static (shared) object or the object's properties in the PropertyGrid?

  • Can you expose XML webservices from a Windows Forms Application?

    - by Andrei
    This might sound like a silly question, but when I search for webservices, I get no information about how to create them in a windows forms application. The only result is how to create and expose them by creating an .aspx page. So my questions is: Can you create and expose webservices within a windows forms application or are they somehow tied in with .asp pages? Thanks! later edit: Is there an example of how to create a webservice in a .cs file and not in a .aspx file?

  • ListView Final Column Autosize creates scrollbar

    - by Courtney de Lautour
    Hi There, I am implementing a custom control which derives from ListView. I would like for the final column to fill the remaining space (Quite a common task), I have gone about this via overriding the OnResize method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (Columns.Count == 0) return; Columns[Columns.Count - 1].Width = -2; // -2 = Fill remaining space } or via another method: protected override void OnResize(EventArgs e) { base.OnResize(e); if (!_autoFillLastColumn) return; if (Columns.Count == 0) return; int TotalWidth = 0; int i = 0; for (; i < Columns.Count - 1; i++) { TotalWidth += Columns[i].Width; } Columns[i].Width = this.DisplayRectangle.Width - TotalWidth; } Edit: This works fine until I dock the ListView into a parent container and resize via that control. Every second time the control size shrinks (IE, drag the the border one pixel), I get a scroll bar on the bottom which can't move at all (not even one pixel). The result of which is when I drag the size of the parent I am left with a flickering scroll bar in the ListView, and a 50% chance it will be there when the dragging stops.

    - by peace
    Contact Title has a default value which is Sales Person. Anyhow, when a user click Edit on the chosen ListView record, i need Contact Title to have the right value that corresponds to the chosen record. For example, if user clicks edit, the fields on the left side will be filled with values. In this case, i want Contact Title to view the right value. How can i do it? I hope my question is clear enough.

  • Windows.Forms.Timer instance and UI threads

    - by David Rutten
    I have a custom control whose primary purpose is to draw data. I want to add a ScheduleUpdate(int milliSeconds) method to the control which will force an update X milliseconds from now. Since this is all GUI land, I should be using a Windows.Forms.Timer, but how does this timer instance know which thread it belongs to? What if ScheduleUpdate() is called from a non-UI thread? Should I construct the timer in the Control constructor? Or perhaps the Load event? Or is it safe to postpone construction until I'm inside ScheduleUpdate()? I know there are some very similar questions about this already, but I don't have a Timer component on my control, I'm constructing it on a when-it's-needed basis.

  • Is this part of MVC in .NET?

    - by 4thSpace
    I have a .NET MVC winform app. I've created an AppDelegate class that handles application startup and shutdown...for now (it might do more later). Winform apps have a Program.cs file that does some app initialization, starts the message pump and creates the first form. In my app, the first form is AppDelegate, which isn't really a form but is forced that way by Application.Run(). AppDelegate does any further app initialization and starts the first Controller, which then initializes any child controllers (these then create their views). I don't consider events occuring in Program.cs and AppDelegate as part of the MVC. Conceptually, what would these be called?

  • Automatically resize TableLayoutPanel

    - by Armagan
    I have a programmatically created TableLayoutPanel. It works fine but I couldn't find something: how can I make it size columns automatically when the form is resized? The panel is set to Dock.Top and when I resize the form instead of sizing every column as percents, only last column grows. What can I do for this? Here's how I add ColumnStyle for each column: this.tablePanelFilter.ColumnStyles.Add( new ColumnStyle(SizeType.Percent,Convert.ToSingle( Math.Ceiling((decimal)100 / (decimal)columnCount))));

  • Of Datagridviews, databinding, and non validating cell values.

    - by Yanko Hernández Alvarez
    Lets simplify. Lets say I have this class: class T { public string Name { get; set; } public int Age { get; set; } public int height{ get; set; } ... } and I have a DataGridView's DataSource bound to a BindingList <T>, with N columns, each one bound to each property. I need to: Allow the user to enter non validating ages, heights, etc (for instance "aaa") Color the cells with non validating values (red background) Retain the non validating values displayed until the form is closed (I don't want to lose the values entered until the form is closed, so the user has the option to correct the bad cells anytime he wants BEFORE closing the form) Keep the last correct values entered for each cell with non validating values entered. When the form is closed, ditch the non validating values and keep the last correct values entered. Is there any easy way to do this?

  • Why does this IF statement fail?

    - by ChosenOne
    If variable path is empty, and editor.Text is not empty, the SaveFileDialog should be displayed. Now, why on earth is this damn thing failing??? I have tried this with many different variations of code with the same result: FAIL: if(path.Length >= 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } At the top of code file I have: path = String.Empty; So why the heck it this failing every single time, even after trying all of the below variations? if(path.Length > 1) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrEmpty(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } and if(String.IsNullOrWhiteSpace(path)) // path contains a path. Save changes instead of creating NEW file. { File.WriteAllText(path, content); } else { // no path defined. Create new file and write to it. using(SaveFileDialog saver = new SaveFileDialog()) { if(saver.ShowDialog() == DialogButtons.OK) { File.WriteAllText(saver.Filename, content); } } } This is making me very angry. How could this fail? Setting a break point reveals that path is definitely null/"".

  • How can I obtain a list of modified files within a 'changeset' range from team foundation server thr

    - by Colin W
    I'm trying to create a tool which will help my team perform code reviews on a more regular basis without it's usual massive overhead. At the moment the manual process involves using Team Foundation Sidekicks to identify the Changesets and then exporting that to excel to filter the results to find which items need to be reviewed (e.g. code files). I've heard mention of using a TFS API, but found very little help online possibly because I was asking google 'the wrong questions'.

    We have a desktop application that has been using MapPoint for displaying data on a European map. We now want to support Middle East maps, but MapPoint only support North America and Europe. Is there any other alternative to MapPoint that can be easily integrated in a .NET based Win Forms application?

  • How can I add an Items-like property to my User Control?

    - by Dan Tao
    It's pretty straightforward to add simple properties to a User Control that will appear in the desired categories in the Windows Forms designer, e.g.: [Category("Appearance")] public Color BackColor { get { return _textBox.BackColor; } set { _textBox.BackColor = value; } } What if I want to expose a more complex property, such as a collection of items of a type I define? I'm thinking something along the lines of the ListView.Items property, or the DataGridView.Columns property -- where the user of the control can access this complex property via a more specialized pop-up form (as opposed to a simple TextBox or ComboBox). Even a simple nudge in the right direction would be much appreciated.

    I built a little console application in C# and need to add a windows form interface to it. I added a form item, and now have a blank form.

  • TabControl winform c#

    Hi, Does anyone know why my tabcontrol will not display on this form? Have a feeling it maybe something simple but at the moment i just get a blank form. Thanks using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; namespace test_project_3 { public partial class TabTest : Form { public TabTest() { InitializeComponent(); WebBrowser WB = new WebBrowser(); WB.Navigate("www.google.com"); TabControl tc = new TabControl(); tc.Dock = DockStyle.Fill; tc.Show(); TabPage tp = new TabPage(); tp.Text = "test"; tp.Show(); tp.Controls.Add(WB); tc.TabPages.Add(tp); } } }

  • C#: standard Windows menu bars in Windows Forms

    - by BoltClock
    I noticed that adding a MenuStrip (from the VS Toolbox) to my form design doesn't yield a menu bar like many native Windows applications. Instead I get a menu bar like VS's own. None of the style settings for MenuStrip appear to mimic the much more common native menu bar. Is there a way to add a menu bar to my Windows Forms application that looks the same as the one you see in Notepad, Task Manager, Windows Explorer and others? (Preferably with the designer, but I wouldn't mind adding it programmatically either.)

  • form not showing

    - by Luke
    Perhaps this has something to do with it being the mainForm, but I'll ask the question. I have my mainForm that is the first to load when the program is booted. I then click a button called Add, which should open a new form, and close the mainForm. The problem is, is shows the new form for a split second, then closes both. The code: private void addFrmBtn_Click(object sender, EventArgs e) { saveForm saveform = new saveForm(); saveform.Show(); this.Close(); }

  • After drawing circles on C# form how can i know on what circle i clicked?

    - by SorinA.
    I have to represent graphically an oriented graph like in the image below. i have a C# form, when i click with the mouse on it i have to draw a node. If i click somewhere on the form where is not already a node drawn it means i cliked with the intetion of drawing a node, if it is a node there i must select it and memorize it. On the next mouse click if i touch a place where there is not already a node drawn it means like before that i want to draw a new node, if it is a node where i clicked i need to draw the line from the first memorized node to the selected one and add road cost details. i know how to draw the circles that represent the nodes of the graph when i click on the form. i'm using the following code: namespace RepGraficaAUnuiGraf { public partial class Form1 : Form { Graphics graphDrawingArea; Bitmap bmpDrawingArea; Graphics graph; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graph = Graphics.FromHwnd(this.Handle); } private void Form1_Click(object sender, EventArgs e) { DrawCentralCircle(((MouseEventArgs)e).X, ((MouseEventArgs)e).Y, 15); graph.DrawImage(bmpDrawingArea, 0, 0); } void DrawCentralCircle(int CenterX, int CenterY, int Radius) { int start = CenterX - Radius; int end = CenterY - Radius; int diam = Radius * 2; bmpDrawingArea = new Bitmap(Width, Height); graphDrawingArea = Graphics.FromImage(bmpDrawingArea); graphDrawingArea.DrawEllipse(new Pen(Color.Blue), start, end, diam, diam); graphDrawingArea.DrawString("1", new Font("Tahoma", 13), Brushes.Black, new PointF(CenterX - 8, CenterY - 10)); } } } My question is how can i find out if at the coordinates (x,y) on my form i drew a node and which one is it? I thought of representing the nodes as buttons, having a tag or something similar as the node number(which in drawing should be 1 for Santa Barbara, 2 for Barstow etc.)
