    - How to specify new DataRow as selected row in sorted DataGrid I'm using c#, my DataTable is the datasource for a DataGrid, and the key in the DataTable, "ID" column, is an autoincrement number The Datagrid is not editable, data is added to the DataTable programatically. When I add a new DataRow to a DataTable using: dr =DataTable.NewRow(); ..code to fill the row.. dataAdapter.Update(DataTable); I can get the ID of the new DataRow using @@IDENTITY as shown in the post "Getting Autoincrement ID in ADO.NET". How do I make the newly added DataRow the selected row in the DataGrid, which may be sorted? Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95251

    - Want a multi-line row in DataGridView Greetings, I am working on a ledger-style display using the DataGridView. I have found a couple of ridiculously complicated ways that I can display a second-line of information (all from the same DataRow) in the DataGridView, but I was wondering what the recommended approach for this is. The DGV is supposedly far more configurable than its WinForms 1.1 predecessor, but lately I'm finding that I'm going to have to write almost as much hacking code for the DGV as I did for the DataGrid. Does anyone have a sample of a way in which I can display 2 lines of data in a DataGridView? My first approach was to create custom columns that had a cell type that displayed two lines of data, but I wasn't sure how to get that to work well within edit mode and read mode, etc. Any help would be greatly appreciated.

    - ClickOnce settings disappear I have deployed my application with ClickOnce, and it works fine. There are a couple of user settings that the user is allowed to change through a settings form. Also works fine. BUT, when I did the most recent deploy all user settings were erased and set back to their default values. NOT FINE! I quote from the blog on: http://blogs.msdn.com/rprabhu/articles/433979.aspx "Q: Okay, but how do I know when to call Upgrade? A: Good question. In Clickonce, when you install a new version of your application, ApplicationSettingsBase will detect it and automatically upgrade settings for you at the point settings are loaded. In non-Clickonce cases, there is no automatic upgrade - you have to call Upgrade yourself. ....." So, normally the sepcified user settings should be upgraded automatically, and I am pretty sure I got that behaviour before. What can I possible have done? How can I get it back?

    - Maximize and resize Windows Dear all, I am a newby of .NET programming and I have a general question. If I put some controls on a windows form (say with size 300,400), when I resize the Window (enlarging it) or if I Maximize it, the controls remain in the top left corner in the rectangle 300,400 making the whole form look very bad. If I resize Notepad, the multiline textbox within resizes too... I'd like my applications do the same. Are there techniques, articles, tutorials or something like that, that can explain me how to handle this? Thanks in advance.

    - FormView / GridView Connection If someone could help... My goal is to attach a FormView control to a GridView control such that clicking the Select link on a record in the GridView will cause that record to be displayed in the FormView control. So far I've got the GridView displaying all the correct records, and the FormView populating on the page's initial load. The FormView has its own data source - it points to the same table the GridView uses, but has a 'where' clause that refers back to the GridView control on two fields. The datasource has default values for those two fields, and the data that is displayed on the initial page load reflects the record whose keys equal the default values. So far, so good. When I click another line's Select link, the page repaints, but the FormView control is empty. Viewing the source I can see its skeleton, but no content. I've breakpointed at the control's PreRender function, and the DataItem is populated on the initial page load, but is null on the postback. I'm sure I'm missing something fairly basic. Can I get a point in the right direction? Thanks, Ben -- bf001removethis@abovetheline.biz Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95231

    - Problem creating controls from other thread w/ invoke Hi, I have a form which acts as monitor for a service. The form and the monitor communicate via remoting. Because it takes some time for the service to startup some controls are added to the form when a certain event is raised by the service. However, when handling this event I do the following: --------- snip --------- private void EventProxy_Initialized(object sender, EventArgs e) { MethodInvoker invoker = new MethodInvoker(this.CreateCommunicatorControls); this.Invoke(invoker); } private void CreateCommunicatorControls() { // create controls and add them to a panel on the form this.panelCommunicator.Controls.Add(newCommCtrl); [...] } --------- snip --------- The panel on the form is created from the main UI thread of the form., but I still get the exception "Controls created on one thread cannot be parented to controls on a different thread" when adding the new control to the panel. Does anybody know what the problem is? Regards, Michael Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95226

    - How to show fields from related tables in same datagrid I run VS .Net 2003. I have a distributed application with sql server 2000 and windows front end, written in c#. I have a number of tables in a dataset with relations between them. In one single read-only datagrid I would like to display child rows from a child table as well as one column from the parent table. How can I fix this in an easy way? I thought I could handle this via dataviews and dataviewmanager as source for the datagrid, but I have not found any good article. I need a detailed explanation as I am a novice on this. I realize I could produce a new table on the windows client from the two related tables, but as I consider the data structure to be well designed this is not what I would like to do.

    - How to draw a 1 pixel long line using Graphics.DrawLine? I am writing a Windows Forms application graphing routine using VS.NET 2003, Visual C# and .NET Framework 1.1. The Graphics.DrawLine(Pen,int,int,int,int) method seems to work okay unless the desired line being drawn is only one pixel long (horizontally). I have not found a way to get a horizontal line of only one pixel to be drawn. I either get no line or a two pixel line. Example method calls: Graphics.DrawLine( Pen, 20, 50, 21, 50 ); // Results in two pixel long line. Graphics.DrawLine( Pen, 20, 50, 20, 50 ); // Results in no pixels being drawn. So how do I get a one pixel long line? Thanks, Dave Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95205

    - ClickOnce I have today gone to production with my first .net 2.0 Windows forms app. I distributed it using click once. I was impressed with the .net framework 1.1, 2.0 looked even better from a developer point of view (generics are brilliant). But I have to say click once is the best thing microsoft has ever done. I published the app to my webserver, sent everyone a link, sat back and grinned. It felt so good I even built a quick enhancement just so i could do an update in the afternoon. The last software distribution i did was a vb6 app and involved sending ~20Mb of install set around to 100+ people, so you can imagine how good this felt. Well done microsoft! If you havent played with this technology then i would definitely suggest you have a go. Desktop Apps are back!

    - Painting Problem Hello, I am currently using VB 2005 and having a problem I hope that some one can help me with. Currently in my project, I create and add a panel at run time and on this panel, I draw a gradient along with several text strings. This panel is docked at the top of the form and I also create another that is docked at the bottom of the form. The problem I am experiencing is that whenever I hover over the min/max button or bring up any shortcut menus like clicking on the control box, where ever the tooltip or pop up menu was will leave nothing but the background color of the panel instead of refreshing the the gradient and any strings drawn in that section as well. However, this only happens when the first one pops up, if any more pop up after that, the panel seems to paint correctly in that area when the popup/tooltip disappears (although the previous area will remain blank). If I minimize the form and then bring it back up, the entire form is correctly drawn, but the problem happens exactly as it did before where the first popup causes a problem and the rest do not. The second part of the problem is when tabbing over to another control... all of a sudden both panels drawn will go completely blank to whatever the default background color is and will only come back if minimizing the form and bringing it back up again. Below is the code I am using in my form (the panels uxHeader/uxFooter are simply added during the form_load event with all their defaults aside of dock and height), hopefully someone can see my problem or suggest a resolution to it, thanks in advance: Public Class form_main Private Sub form_main_Paint( _ ByVal sender As Object, _ ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint DrawGradient( _ 0, 0, uxHeader.Width, uxHeader.Height, _ Color.Black, Color.LightSlateGray, uxHeader, Drawing.Drawing2D.LinearGradientMode.Vertical) DrawGradient( _ 0, 0, uxFooter.Width, uxFooter.Height, _ Color.LightSlateGray, Color.Black, uxFooter, Drawing.Drawing2D.LinearGradientMode.Vertical) DrawString( _ uxHeader, "Data Copy Setup", Brushes.SteelBlue, 11, 48, _ New Font("Trebuchet MS", 14, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Data Copy Setup", Brushes.White, 10, 47, _ New Font("Trebuchet MS", 14, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Citizens Bank", Brushes.SteelBlue, 306, 10, _ New Font("Trebuchet MS", 12, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Citizens Bank", Brushes.White, 305, 9, _ New Font("Trebuchet MS", 12, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Wintel Services", Brushes.SteelBlue, 306, 23, _ New Font("Trebuchet MS", 24, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Wintel Services", Brushes.White, 305, 22, _ New Font("Trebuchet MS", 24, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Migration Data Copy Tool", Brushes.SteelBlue, 338, 48, _ New Font("Trebuchet MS", 12, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxHeader, "Migration Data Copy Tool", Brushes.White, 337, 47, _ New Font("Trebuchet MS", 12, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxFooter, "version 1.0.0", Brushes.SteelBlue, 416, 21, _ New Font("Trebuchet MS", 10, FontStyle.Bold, GraphicsUnit.Pixel)) DrawString( _ uxFooter, "version 1.0.0", Brushes.White, 415, 20, _ New Font("Trebuchet MS", 10, FontStyle.Bold, GraphicsUnit.Pixel)) End Sub '--------------------------------------------------------------------------------------------------------------------------------- ' Sample Call: ' ' DrawGradient( _ ' 0, 0, uxHeader.Width, uxHeader.Height, _ ' Color.Black, Color.Gainsboro, uxHeader, Drawing.Drawing2D.LinearGradientMode.Vertical) '--------------------------------------------------------------------------------------------------------------------------------- Private Sub DrawGradient( _ ByVal x As Integer, _ ByVal y As Integer, _ ByVal w As Integer, _ ByVal h As Integer, _ ByVal color1 As Color, _ ByVal color2 As Color, _ ByVal ctrl As Control, _ ByVal mode As System.Drawing.Drawing2D.LinearGradientMode) Dim a As New System.Drawing.Drawing2D.LinearGradientBrush(New RectangleF(0, 0, ctrl.Width, ctrl.Height), color1, color2, mode) Dim g As Graphics = ctrl.CreateGraphics g.FillRectangle(a, New RectangleF(x, y, w, h)) g.Dispose() End Sub '--------------------------------------------------------------------------------------------------------------------------------- ' Sample Call: ' ' DrawGradientString( _ ' "Sample", Color.Blue, Color.Firebrick, _ ' Drawing.Drawing2D.LinearGradientMode.Vertical) '--------------------------------------------------------------------------------------------------------------------------------- Private Sub DrawGradientString( _ ByVal text As String, _ ByVal color1 As Color, _ ByVal color2 As Color, _ ByVal mode As System.Drawing.Drawing2D.LinearGradientMode) Dim a As New System.Drawing.Drawing2D.LinearGradientBrush(New RectangleF(0, 0, 100, 19), color1, color2, mode) Dim g As Graphics = Me.CreateGraphics Dim f As Font f = New Font("verdana", 16, FontStyle.Bold, GraphicsUnit.Pixel) g.DrawString(text, f, a, 10, 100) g.Dispose() End Sub '--------------------------------------------------------------------------------------------------------------------------------- ' Sample Call: ' ' DrawString( _ ' Me, "Wintel Operations", Brushes.Black, 12, 102, _ ' New Font("Trebuchet MS", 24, FontStyle.Bold, GraphicsUnit.Pixel)) '--------------------------------------------------------------------------------------------------------------------------------- Private Sub DrawString( _ ByVal ctrl As Control, _ ByVal text As String, _ ByVal b As Brush, _ ByVal x As Integer, _ ByVal y As Integer, _ ByVal f As Font) Dim g As Graphics = ctrl.CreateGraphics g.DrawString(text, f, b, x, y) g.Dispose() End Sub End Class Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95199

    - Derived DataGrid not displeyed correctly Hi! I derived a new class from a DataGrid control and added some functionality to it. Among other things a method that autosizes the columns displayed. When I change the data source and data member of the datagrid after having updated some data in it, it sometimes does not display correctly. What happens is that some cells from the old view is visible in the new view. I do not know what is the problem, but my guess is that it has something to do with the repainting of the derived datagrid.

    - Screen Savers: How do I spawn a process... I have a machine that will be used to demo some Excel spreadsheets at a convention. Because I did not author the spreadsheets and attendees will be allowed to play with the spreadsheets, I needed a way to periodically restore the original versions. In addition to the "always-on-top click this button to reset demo" application I wrote, I chose to use screen saver code to reset the demo after a period of inactivity in the event an attendee just walked away. I chose the screen saver method because I was unsure how to capture the system traps since my reset-app will not always have focus and so using the screen saver method seemed to be the quickest/easiest solution. So... I can spawn a new process from an application and that process remains running after the application is closed. This is good. Using the same code in a screen saver and running it while its an .EXE (prior to renaming it .SCR & relocating it to the system directory), the new process remains running after the screen saver application is closed. This is good. I rename the screen saver to .SCR, relocate it in the system directory, right-click the Desktop background, select Properties / Screen Saver / etc., click the Preview button to execute the screen saver and the new process remains running after I select Ok or Cancel to cancel the screen saver. This is good. Now I allow the system to kick off the screen saver at whatever inactivity timeout. The screen saver executes, the new process executes but it closes when the screen saver closes. This is bad. Here is the code being used: private void ScreenSaverForm_Load(object sender, System.EventArgs e) { string InstallPath = (string)Registry.LocalMachine.OpenSubKey(@"SOFTWARE\MyApp").GetValue(@"Path"); ProcessStartInfo startInfo = new ProcessStartInfo(InstallPath + @"\MyFile.xls"); startInfo.WindowStyle = ProcessWindowStyle.Maximized; Process.Start(startInfo); Close(); } I have also tried including "startInfo.UseShellExecute = true;" but results were the same. Unless I am totally off then obviously the operating system is handling/executing screen saver code differently at the final stage. Other than basic skeleton code required for a screen saver, I am unable to find any 'real' documentation on screen saver programming. For example, through trial & error I discovered that the screen saver filename must follow the 8.3 naming convention - unless I'm doing something wrong there as well? Anyway... 1. Most importantly, what is the code for spawning a new process from within a system activated screen saver such that the new process remains running after the screen saver closes? 2. Is a screen saver filename in fact limited to the 8.3 naming convention? 3. Where is the screen saver application name set or read from? For example; if your filename is 'ssMyDemo.scr' then the system will drop the prefix of 'ss' and display 'MyDemo' in the screen saver list. If there is no 'ss' then the filename, excluding extension, will display in the screen saver list. But if you examine a default OS provided screen saver you will see that the filename 'ss3dfo.scr' displays as '3D Flying Objects' in the screen saver list. How is this accomplished? 4. Is there a "Everything you ever wanted to know" type source on screen saver programming; net, book or otherwise?

    - Event question I have a component (Say Component1 )which has two public functions and one event(Say Func1 and Func2 and event is MyEvent) This component is being used by a second component(Say Component2) Here is the flow of events 1) Component2 intantiates Component1 2) Component2 registers for the event MyEvent 3) Component2 calls function Func1 4) In Func1 of Component1 the event MyEvent is raised. Func1 has to do more work but event is raised in the middle of Func1. 5) Component2 receives event and calls Func2. In this test case I just want to know is there a way to detect/prevent Component2 from calling Func2 until the call to Func1 ends. It is kind of reentry problem of the Component1. Because the Component1 is not thread safe. The Func2 changes the state of the Component2. In this case after executing Func2 the code will fall back to Func1 which will see a changed state. Is there a way to stop it or making Component2 not to be re-entrant. Thanks in advance Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95192

    - Disable Sorting in VB.NET I thought the only thing I had to do to disable column sorting in VB.NET was to set datagrid.AllowSorting = False. Unfortunately this has never worked for me. I discovered another set of code that seems to work for 99% of the cases where I need to disable datagrid column sorting: Private Sub datagrid_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles datagrid.MouseDown Dim pt As New Point(e.X, e.Y) Dim hti As DataGrid.HitTestInfo = dgACE.HitTest(pt) If hti.Type <> DataGrid.HitTestType.ColumnHeader Then MyBase.OnMouseDown(e) End If End Sub However, this code does not work when my datagrid resides on a user control. The datagrid_MouseDown event is triggered but sorting still occurs for the column. It's critical that I disable sorting in the datagrid due to the other things I am trying to do with the datagrid. I'm about ready to pull my hair out trying to figure this one out so any suggestions on how to resolve this issue would be greatly appreciated! Thank you!

    - How to combine AutoScroll and virtual content scroll I am a .NET newbie and started working on al user control, where one scroll dimension -- say horizontal -- moves the contained controls (like AutoScroll) and the other dimension leaves the controls sticky and updates the virtual content of the contained controls -- lets say some text boxes -- with .NET 2.0. I tried to use AutoScroll by setting ScrollableControl.AutoScrollMinSize.Height to the virtual content size and updating the content of my text boxes by using a Scroll event handler. But this also moved my text boxes vertically and I was not able to reset their location without introducing flickering. Question: Is there a way to make some contained controls remain sticky or is there a way to make to movement of the controls invisible? My second approach was to use manual scrolling. Besides that this approach introduces a lot more code and I had to do the layout manually, it introduced flickering of the scroll bars when resizing. I assume that this is introduced by the timig of layouting and control-repainting. With my first approach by using AutoScroll there was no flickering when resizing the control. Question: Is there a flicker save way to do layouting and painting of contained controls. Thanks in advance for any hints. But I want to do it purely using platform independent .NET code, so overriding WndProc or using P-Invoke is not an option for me.

    - Fonts and Labels in a Windows Form Messed Up? I'm converting a .NET 2.0 Beta project to the final version using Visual Studio. In doing so, I've come across a strange problem with the fonts in my labels. To see the problem, I have an empty form with 2 labels, one "Timing Details:" and one "Package Details:" - each one Bolded. When viewing the form in design mode within Visual Studio, everything looks good - as expected. But when I run the form, the word "Details" in each of the two labels looks different. The second one looks scrunched up. Here's the guts of my form code - nothing out of the ordinary as far as I can tell: partial class Form1 { private void InitializeComponent() { this.packageDetailsGroupLabel = new System.Windows.Forms.Label(); this.timeDetailsGroupLabel = new System.Windows.Forms.Label(); this.SuspendLayout(); // // packageDetailsGroupLabel // this.packageDetailsGroupLabel.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0))); this.packageDetailsGroupLabel.Location = new System.Drawing.Point(12, 47); this.packageDetailsGroupLabel.Name = "packageDetailsGroupLabel"; this.packageDetailsGroupLabel.Size = new System.Drawing.Size(163, 13); this.packageDetailsGroupLabel.TabIndex = 22; this.packageDetailsGroupLabel.Text = "Package Details:"; // // timeDetailsGroupLabel // this.timeDetailsGroupLabel.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0))); this.timeDetailsGroupLabel.Location = new System.Drawing.Point(12, 9); this.timeDetailsGroupLabel.Name = "timeDetailsGroupLabel"; this.timeDetailsGroupLabel.Size = new System.Drawing.Size(163, 13); this.timeDetailsGroupLabel.TabIndex = 21; this.timeDetailsGroupLabel.Text = "Timing Details:"; // // Form1 // this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(220, 79); this.Controls.Add(this.packageDetailsGroupLabel); this.Controls.Add(this.timeDetailsGroupLabel); this.Name = "Form1"; this.Text = "Form1"; this.Load += new System.EventHandler(this.Form1_Load); this.ResumeLayout(false); } private System.Windows.Forms.Label packageDetailsGroupLabel; private System.Windows.Forms.Label timeDetailsGroupLabel; } If you have any ideas, or would like to see a screenshot of what I'm talking about, please let me know.

    - Visual Studio macro running as a STA thread Dear All, We have written a small set of dlls that contain some WinForms...we lauch these forms in Visual Studio using a macro. By default the macro thread is a MTA thread. Are there any issues if we make this thread an STA thread? I need this as an STA thread as the user wants to copy some elements from the grid in the clipboard. I don't want to create a separate STA thread for the copy functionality. Why is the macro thread an MTA thread? Is MS planning to change it back to STA thread? Please help Thanks in advance...

    - Is IMessageFilter only for .net windows? Hi; (I am trying to figure out the best way to intercept Word's message pump in a .net app.) It looks like an IMessageFilter object can only be attached to the message pum of a .net Application so it could not be used with Word. Is this correct? -- thanks - dave Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95163

    - NativeWindow.ReleaseHandle Hi; I want to use NativeWindow to wrap the hwnd of Word (which is already running and so the window exists). I need to release the handle and dispose my NativeWindow object when the window goes away. As Word is not a .net app, it does not have .net windows and therefore I can't have it call an event. Do I just watch for the WM_DESTROY message in the message pump? -- thanks - dave Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95162

    - Databound ListBox Won't Update on Clear? I have a ListBox control bound to an ArrayList: m_expressionFilters = New ArrayList m_expressionBindingManager = BindingContext(m_expressionFilters) lstboxFilters.DataSource = m_expressionFilters When I add an Item to the ArrayList, that change is immediately reflected in the ListBox: m_expressionBindingManager.SuspendBinding() m_expressionFilters.Add(CurrentFilter) m_expressionBindingManager.ResumeBinding() However, when I call the Clear method of the ArrayList, the changes are not reflected in the ListBox: m_expressionBindingManager.SuspendBinding() m_expressionFilters.Clear() m_expressionBindingManager.ResumeBinding() At this point, the m_expressionFilters ArrayList has a Count of zero, but the Items formerly held in the ArrayList are still listed on the form in the ListBox. I have tried calling the Refresh and Update methods on the ListBox, but that produced no visible changes at all. Any help or advice would be greatly appreciated.

    - crystal integration Using v1.1 of the .Net Framework, I added a Crystal Report item to my solution as an embedded resource. My problem is that when I drop a ReportDocument component onto my form, the window that prompts me to select a typed reportDocument does not include in its drop-down the embedded report that I added, and so I can't integrate the report into the form thru the crystalReportViewer. Any idea why I wouldn't see the report show up in the drop-down? Thanks! Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95147

    - Handling System Shutdown in a WindowsForms App Hi. I have an application that runs as a Tray Icon app with no visible window (most of the time) and right now, the system will not shut down while that app is running. I think I need to handle "SystemEvents.SessionEnded" or something to properly deal with that but I don't understand how, inside the code for my Main Form for the application, I set up a handler for the event and then what I actually DO with the event once it comes (though I assume I just do whatever I would normally do to exit my application grcefully). Can someone help me with a sample? Alex Tag: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95141

    - Detect any kind of activity in a window. 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?

    - 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?

    - 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?

    - 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: Making UltraTreeNode in-place editable after adding it to the tree at run time Tag: 95127

    - 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: Making UltraTreeNode in-place editable after adding it to the tree at run time 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?

Hi,

I am an UltraTreeNode to Ultra at runtime. I want the control to be
in-place editable after adding it so that user can change the name. The
behaviour I am expecting is something like creating a new folder in
windows. When a new folder is created, the name is in-place editable.
Same has to be with adding node.

Can anyone help me in this regard?

Thanks in advance
Kiran

Its probably best to post questions about the Infragistics control on
Infragistic's newsgroups -
http://devcenter.infragistics.com/DevCom/NewsGroups.Aspx. With regards to
allowing a node to be edited, you can set the Override->LabelEdit to true.
