    - ListView.tag lost object Hi, I have a Form with two ListViews; The ListViews are diplayed on the Design surface, but I progmatically adding the items to each ListView. When adding the items to the list view I am iterating through and setting the following: ... With myListViewItem .Text = drArticles("Title").ToString .ToolTipText = drArticles("Summary").tostring .Tag = CType(drArticles("ID"),Guid) End With myListView.Items.Add ... This works fine and the items are displayed. The problem arises when I respond to a SelectedIndexChanged event I can retrieve the .ToolTipText and .Text values from then SelectedListViewItemCollection but the .tag property is always empty (it knows the object type is GUID but does not have the value. I know the value is being set as I can set the ToolTipText to same ID as the TAG and it is stored correctly. Any ideas? Many thanks in advance Tag: Detect any kind of activity in a window. Tag: 95138

    - General Windows Forms and Memory Question I am seeing an interesting memory issue with a winform in my application. I've noticed everytime I show a form in my application, the memory usage increases. When I close the form, the memory isn't released. The only time the memory is released is when I "minimize" the application. Eventually, overtime, my application consumes a good amount of memory. Has anyone experienced this?

    - ClickOnce returns XML instead of starting application Hi I just deployed a ClickOnce Application to a Windows 2000 Server, which only has .NET 1.1 installed. When I launch the application via the auto generated html page I get the .Application XML back. I was expecting the application to launch. If I deploy the same SmartClient to my local XP machine with .NET 2.0, the applications installs and starts just fine. Am I missing something? Do I need to install .NET 2.0 on the Windows 2000 server, or do I need to register some MIME types on the server? If so, could you please provide a link (I can't find anything in the documentation... but I found place that said that I should be able to deploy to any HTTP 1.1 compliant web server). Please help.

    - .NET 2.0: ToolStripTextBox with Caption? In a Winforms 2.0 application, I have a StatusStrip which hosts a ToolStripDownDown item to display a small menu. The menu consists of two checkable menu items and one ToolStripTextBox . Now I want to display a simple caption on the left of the textbox. I cannot seem to find an easy possiblity to do this, altough this seems a very common scenario to me. After all, which programmer wants to just display a textbox without any caption? Can somebody help me? Do I really have to bake my own control inherited from ToolStripControlHost just for this? Thanks for any help Urs Eichmann Tag: Detect any kind of activity in a window.

    - TabControl.OnDrawItem Hello ppl! I am manually drawing tab items in a TabControl by using a handler attached to the DrawItem event on such control. I am using rectangles inside the Item's region for the background and drawing strings for text using the graphics object provided in the DrawItemEventArgs. I al also painting the aread just to the right of the last tab with another rectangle in the same DrawItem event. The form runs just fine and I can see the tabs asd intended on the initial load. However, as I move the form to either the left or right just beyond the screen, my painted rectangle simply dissapears or gets smeared. If the form is moved beyog the screen's upper or lower boundaries the rectangle gets painted again. This also happens if another window is on top of the tabcontrol. I tried timers for refreshing the control and the form. Tried also a refresh on the form on a Move event and managed to eliminate the problem is the form moves beyond the right screen boundary but still the same problem on the left boundary. Anyway I can work around this? Thanks in advance sampe code of the event handler: private void tabControl1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e) { Graphics g = e.Graphics; int lastTabIndex = this.tabControl1.TabPages.Count-1; System.Drawing.StringFormat textFormat = new StringFormat(); textFormat.Alignment = StringAlignment.Center; textFormat.LineAlignment = StringAlignment.Center; textFormat.Trimming = StringTrimming.None; textFormat.FormatFlags = StringFormatFlags.NoWrap; Rectangle tabRect = this.tabControl1.GetTabRect(e.Index); Rectangle lastTabRect = this.tabControl1.GetTabRect(lastTabIndex); //filler rectangle beyond last tab g.FillRectangle(new SolidBrush(Color.Blue), lastTabRect.Right, lastTabRect.Top, this.tabControl1.DisplayRectangle.Width, lastTabRect.Height); //tab Item background g.FillRectangle(new SolidBrush(Color.Red), tabRect); //Item text g.DrawString(this.tabControl1.TabPages[e.Index].Text, e.Font, new SolidBrush(Color.White), tabRect, textFormat); } Tag: Detect any kind of activity in a window.

    - Splashscreen disappears I added a Splashscreen to my Windows Forms project. I specified it in Project - Application Tab - Splash screen. When I launch the project the splash screen turns up, which is fine. BUT then a NullReferenceException is thrown! I turned on "Break when an Exception is thrown" but it will not stop on a code line that is visible to me. My application uses a frmMain as start form. The frmMain code is enclosed by a Namespace. When I enclosed the SplashScreen code in the same Namespace and modified Project - Application Tab - Splash screen to point out the new full name, then the problem disappears, but so does the SplashScreen .......! As far as I can see there are no more settings I should have set to get it working. Tag: Detect any kind of activity in a window. Tag: 95126

    - Control to graphically connect listviews (or treeviews) Hello. I'm lookin for a way to have two listboxes whose some elements can be connected graphically by an arrow. The arrows should 'move' as the listboxes scroll, 'following' the elements they are attached to. It should be similar to the relations fields in graphic representation of SQL queries (as in Visual Studio's Query Designer) I'd like to have a similar effect with two treeviews (whose element can connected by arrows, as in Biztalk Mapper) Does anyone know if there is a third party control that allow this?

    - Serializing/Deserializing from a Modal UI Editor I created a control that I derived from Windows Forms Control. I added one string property, which is the name of a file. This property is a Modal UI Editor property for which I provided a form named ShapeEditor. When the user presses the ellipsis in the Properties window of the control in the IDE, ShapeEditor is displayed and enables the user to draw shapes. The shape objects are collected in an ArrayList and then serialized to a file using a BinaryFormatter as follows. FileStream sw = new FileStream(ShapesFileName, FileMode.Create); ArrayList Shapes = new ArrayList(); // Create shapes and populate Shapes. .... Shapes.Add(ShapeObject); ..... // Then serialize bf.Serialize(sw, Shapes); // Deserialization is the reverse: Shapes = new ArrayList(); sr = new FileStream(ShapesFileName, FileMode.Open); BinaryFormatter bf = new BinaryFormatter(); Shapes = (ArrayList)bf.Deserialize(sr); // Use objects foreach (ShapeObject s in Shapes) Here is the problem. When I invoke ShapeEditor from the properties window foreach (ShapeObject s in Shapes) fails with an invalid cast exception even though Shapes[0].GetType() returns a ShapeObject. However, if I invoke ShapeEditor from a running program, everything works fine(the same code is executed). It is as if the IDE is somehow interferring with the deserialization. Any help greatly appreciated. Tag: Detect any kind of activity in a window. Tag: 95107

    - BindingSource vs. old binding I'm getting myself confused about the new BindingSource. In the old days I'd bind a combobox like this to show the "productName" field: DataSet ds = getDS(); cboX.DataSource = ds.Tables["Products"]; cboX.ValueMember = "productID"; cboX.DisplayMember = "productName"; Now I guess I can do this: BindingSource bs = new BindingSource(getDS(), "Products"); which sets the bs.DataSource and the bs.DataMember (ie the table within the dataset). But, how do I tell it what field to display when the table has multiple fields? There is no longer any DisplayMember or ValueMember property. Tag: Detect any kind of activity in a window. Tag: 95105

    - Problem changing the size property in the Resize event I am trying to preserve the aspect ratio of a form when it is resized. To simplify the problem, I'm starting with a square form, and trying to keep it square when either the width or height is changed. My code is based on the example found in MSDN, July 2005, for the Control.Resize Event. Here is the relevant code: public class Form1 : System.Windows.Forms.Form { private Size _previousSize; /// <summary> /// Required designer variable. /// </summary> private System.ComponentModel.Container components = null; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); // // TODO: Add any constructor code after InitializeComponent call // _previousSize = this.Size; } private void Form1_Resize(object sender, System.EventArgs e) { Control control = (Control) sender; System.Console.WriteLine( "Height={0}\tWidth={1}", control.Size.Height, control.Size.Width); Size newSize; // Ensure the Form remains square (Height = Width). if (control.Size.Height != _previousSize.Height) { System.Console.WriteLine( "Height changed: oldSize={0}", _previousSize.ToString()); newSize = new Size(control.Size.Height, control.Size.Height); System.Console.WriteLine("newSize={0}\n", newSize.ToString()); _previousSize = newSize; // save new value for previous size control.Size = newSize; } else if (control.Size.Width != _previousSize.Width) { System.Console.WriteLine( "Width changed: oldSize={0}", _previousSize.ToString()); newSize = new Size(control.Size.Width, control.Size.Width); System.Console.WriteLine("newSize={0}\n", newSize.ToString()); _previousSize = newSize; // save new value for previous size control.Size = newSize; } } } My code writes some debugging data to the console. Here is the debugging data that is produced when I execute the Size command from the control menu of my form, and press the right arrow key three times. Height=300 Width=311 Width changed: oldSize={Width=300, Height=300} newSize={Width=311, Height=311} Height=311 Width=311 Height=300 Width=322 Height changed: oldSize={Width=311, Height=311} newSize={Width=300, Height=300} Height=300 Width=300 The first press of the right arrow key just starts the resize operation. On the second press of the key, the code changes the Height from 300 to 311. But on the third press of the key, the Height has changed back to 300 on entry to the Resize event. That is the problem. On the screen, the form alternates between increased sizes and its original size. Does anyone know what's causing this problem? Tag: Detect any kind of activity in a window. Tag: 95104

    - DatagridView, Data Binding, New Row Hi! I have this scenario: I have a windows form. I have a DataGridView Control which is bound to a DataSource. Under the DataGridView I have texboxes which represent each one of the columns in the Datasource (also shown in the datagridview) As I move from row to row, the values of the textboxes (which are also bound to the datasource) change according to the value of each column of such row. That is perfectly normal. I have set the DataGridview not to allow user to add edit or delete rows so they must press a button to "Add New Row". How do I move (Or select) the row pointer to the New row (last row) such that the bound Textboxes point to the new row (showing empty values of course). In this way the user can type any value into the texboxes and therefore update the new row. Thanks! -- I love .NET! Tag: Detect any kind of activity in a window. Tag: 95078

Took me hours to figure out what the problem is and how to reproduce it. The best way to explain how to reproduce it is to explain my need, I want to create a library called "CompanyName.Console" and have a class called Console. But, I don't want the fully qualified namespace and object to be CompanyName.Console.Console (because it is redundant). so do these steps: 1. Create Class Library called "Test.Console" 2. Rename Class1 to Console and the constructure 3. Build it 4. Change the namespace to read CompanyName (instead of CompanyName.Console) 5. Add a new Windows Form. You'll get a Designer exception. If you omit step 4, it works just fine. Is this a bug or design by behavior? Thanks, Shawn Tag: Detect any kind of activity in a window. Tag: 95049

My dataset is linked to my datagrid, so that anytime I change the value of a column in my dataset, the datagrid gets updated. Internal updates are triggered by internal events (timer, remote calls...). But if the user is editing the same row that my program updates, then the current cell edition will be canceled, and the user looses what he is typing. How can I avoid this?

I would imagine that I would have to write some sort of Windows service to keep the application 'alive' and keep track of time. However, I would appreciate if you could let me know some better (more standard) ways of implementing such a functionality. Thanks. Tag: Detect any kind of activity in a window. Tag: 95034

    - Best Way to Check for Dataset Changes vb.net 2.0 VS 2005 What is the best way to check to see if a table in the dataset or the whole dataset has changes? If I use myCurrencyManager = CType(Me.BindingContext(Me.DsMain.tblClient), CurrencyManager) myCurrencyManager.EndCurrentEdit() if dsMain.HasChanges then msgbox("Is Dirty") On my form, I have several controls loaded from the same dataset but different tables using the data wizards. When I put my cursor in a textbox bound to dsMain.tblClient and then put the cursor in a textbox bound to dsMain.tblNotes, the dataset shows it has changes. This is with no data changes and no position changes. What is the best way to check for changes? Regards, Brian Tag: Detect any kind of activity in a window. Tag: 95033

I need to write a function so if the user doesn't do anything in 15 minutes,
it will log them out. I've got the timer set up fine I'm just looking for an
easy way to detect people doing anything. What's the easiest way to do it?
It looks like it may be mousemove on the windows. Is this reasonable?

TIA - Jeff.

The same question has been asked here this week my answer was to hook into
the keyboard and mouse using P/Invoke calls to the SetWindowsHookEx API:

I have used GetLastInputInfo to detect an idle user. Seems to work quite
well for me.
