    - Listen event on the different thread and update data on the UI thread Hi, Sorry for the long class. This time I am sending you much cleaner code. Could you please respond me back, about "how to apply the threading", taking the example of following scenario . namespace ThreadingTest { public class Class1 { public event EventHandler raiseResponse; //Event through which I can send the received data DataFeeder instDataFeeder = new DataFeeder(); //Object created for the datafeeder component. //Constructor public Class1 { //CustomEventHandler is the delegate to handle ResponseData event from the DataFeeder component instDataFeeder.ResponseData += new CustomEventHandler(InstDataFeeder_ResponseData); } public void RequestData() { instDataFeeder.RequestDataFromRemoteServer(); } public void InstDataFeeder_ResponseData(NewDataStructure newData) // NewDataStructure contains multiple rows of data at the same time { //we receive this event really really really fast and I was thinking of putting this event on the separate thread. //Fill Datatable viz. dataTable1 from newData and then raise event If(raiseResponse != null) raiseResponse(dataTable1,EventArgs.Empty); // Sending the datatable in sender to avoid creating a custom class for event argument. } } //In the following usercontrol we need to bind the data received from our own event -- raiseResponse public class GridControl : System.Windows.Forms.UserControl { private DataGrid dataGrid1 = new DataGrid(); Class1 instClass1 = new Class1(); DataTable dt = new DataTable() ; //It has some of the same columns received from the other class, Not creating the full structure for the table. //Constructor public GridControl () { instClass1. raiseResponse += new EventHandler(instClass1_raiseResponse); dataGrid1.DataSource = dt; } public void instClass1_raiseResponse(object sender,EventArgs e) { //If the data is coming up very fast then there will be problem updating the UI and UI will freeze. dataGrid1.SuspendLayout() DataTable dt = (DataTable) sender; // I think assigning to the datatable will update the datagrid. dataGrid1.ResumeLayout() } } } Please help.

    - Framework 1.1 /2.0 Controls Hosted in Internet Explorer Hi All, I have a windows forms controls hosted in IE via the object tag method. The control was built to run on 1.1 of the framework and works fine whilst version 2.0 is not installed on the machine. When version 2 is installed the executables are downloaded to the 2.0 temporary directory, even though the assemblies where build under 1.1 and are referencing the 1.1 framework. That is, when 2.0 is installed they are downloaded to Documents & Settings\<CurrentUser>\Local Settings\Application Data\assembly\dll3 instead of Documents & Settings\<CurrentUser>\Local Settings\Application Data\assembly\dll2. Could anyone tell me if there is a setting to force IE to use the 1.1 temp download cache? Or is it another assembly setting?

    - MVC delegate problem... In order to become more familiar with the Model-View-Controller pattern, I have written a demo where each View is a plugin and the plugins are loaded at startup from the plugins directory. When the View's are loaded they add themselves to the DataModel View list... FDataModel.AddView(this); Where AddView looks like this... public void AddView( MvcView view ) { ViewChanged += new ViewChangedHandler(view.DataModified); } and at the right time I invoke the event list via... ViewChanged(this, e); This all works fine as long as I only have 1 instance of each type of view. So in this case I have a Pie Chart View and Bar Chart view of the data ( as well as the usual DataGrid view all as plugins ). Then the delegates correctly fire and everything works as advertised. The problem arises if I instantiate a second instance of say the Bar Chart. When that happens the first Bar Chart stops responding/refreshing while the second Bar Chart updates correctly. Can any C# pattern gurus shed some light on what I might have overlooked? Tag: VS .NET 2003 - Cannot create items in Enterprise Framework projects Tag: 95274

    - ComboBox.SelectedIndex behavior I am using a combobox in an application that is databound to a datatable. The visible item in the combobox corresponds to the job classification of an employee: accountant, manager, etc. Due to data entry errors, some employees do not have a classification in the db. For these entries, I want the combobox to display nothing. I accomplish this by setting the combobox's selectedIndex property to -1. In doing so, I encountered some interesting behavior. setting SelectedIndex = -1 always sets the SelectedIndex to 0, UNLESS the SelectedIndex is already 0 or -1. (example) myComboBox.SelectedIndex = -1; produces a SelectedIndex of 0. myComboBox.SelectedIndex = -1; myComboBox.SelectedIndex = -1; or myComboBox.SelectedIndex = -0; myComboBox.SelectedIndex = -1; produces a SelectedIndex of -1. Is this the expected behavior of this control, or is this a bug in the control? I'm using VS.NET 2003 and .NET 1.1.

    - 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?

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.

    - 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: VS .NET 2003 - Cannot create items in Enterprise Framework projects Tag: 95231

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.

    - 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.

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: VS .NET 2003 - Cannot create items in Enterprise Framework projects Tag: 95205

    - Playing File Progress AVI Is there a way in VB.NET 2005 to play the file progress avi file on a Winform? I know there use to be a control in VB6 but there does not seem to be one for .NET.

    - 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: VS .NET 2003 - Cannot create items in Enterprise Framework projects Tag: 95199

    - Multi-page configuration with TreeView. How is it done? Hi there, I need to do something like the Visual Studio "settings" window, i.e., having a TreeView on the left side and some kind of multi-panel (or multi-page) control on the right side.

    - 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. Do I need to do something in the derived data grid to get the painting to work correctly? -- / ScubaD Tag: VS .NET 2003 - Cannot create items in Enterprise Framework projects Tag: 95194

    - 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: VS .NET 2003 - Cannot create items in Enterprise Framework projects 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!

    - FlowLayoutPanel - Move Control (.NET 2.0) Is there a way of changing the position of a control in a FlowLayoutPanel?

    - 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.

Hello everyone,

I have made a few templates for all sorts of items (forms, usercontrols,
components...) and added them so I can pick them up from Project\Add\Add New
Item... menu. I have also made some changes to DAP.TDL and VSIDE.tdl policy
files. Everything was fine until yesterday when I have tried to change one
add-in that adds a few items automatically from templates.

I do not really know what went wrong but now I cannot add any item to
Enterprise framework projects. I can only add a DataSet in simple windows
project.

for example, when I try to add a form to project I get message:

"Could not run the 'C:\Program Files\Microsoft Visual Studio .NET
2003\VC#\CSharpProjectItems\LocalProjectItems\..\CSharpAddWinFormWiz.vsz'
wizard."

I would appreciate any clue.

TIA,

Vlado
