 - Application.Exit After Event Fires I am using the webbrowser control in a winforms app. It is an unattended app, so as soon as the event "form1_shown" is fired the webbrowser control loads a url and then wires the print event as such, prints the document, and is then supposed to exit the app. webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(PrintDocument); the print document event prints the document (without a print dialog) after the webbrowser control is loaded. I've noticed that the actual print does not take place until this event code is run and control is returned form1. My question is, I want to call Application.Exit after printing is complete, but I do not see an event available in the webbrowser control. How do I exit out of the app after the printing is done? Note, If I place the application.exit() within the print event at the end, the application always exits before the document is printed. private void PrintDocument(object sender, WebBrowserDocumentCompletedEventArgs e) { try { // Print the document now that it is fully loaded. ((System.Windows.Forms.WebBrowser)sender).Print(); // Dispose the WebBrowser now that the task is complete. ((System.Windows.Forms.WebBrowser)sender).Dispose(); } catch (Exception ex) { } } Tag: How to prevent window activation when tray icon clicked? Tag: 116425

 - Update datagridview from related controls Hi, I'm having a bit of a problem getting a particular type of form layout to work as I wish. Please bear with me as this isn't going to be a short post. The basic idea is for a form to view/edit a single table. The layout that I'm after is for a datagridview in a panel at the top of the form showing the 'headline' fields. The bottom of the form (in another panel) contains controls to show *all* of the fields for each record. The columns are a mixture of straight text (so a textbox in the bottom detail section), booleans (check boxes), dates (datetimepickers), and text from a list (combos). It almost works perfectly, but there are a couple of glitches. What I'm doing is this... When loading the form, I'm grabbing the dataset from SQL, setting up a dataview based on that, setting the dataview as the datasource for the datagridview, setting up another dataview (that will always be a single record) that will be the source for all the bottom panel controls and then setting the bindings for the controls in the bottom panel. To clarify the last two parts of that I have... Private Sub DG_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Try SetDetails(Me.DG.Item(0, _ Me.DG.CurrentCell.RowIndex).Value) Me.DG.Rows(Me.DG. _ CurrentCell.RowIndex).Selected = True Catch ex As Exceptio End Try End Sub Try Catch required just to avoid it going bang when initialising. Private Sub SetDetails(ByVal id As Integer) DetailRow.RowFilter = "ID=" + id.ToString End Sub The bindings are set while the form is loading with this (indents removed to try to avoid word wrapping): Private Sub SetBindings() bm = CType(BindingContext(DetailRow), CurrencyManager) Dim ctl As Control, cboctl As ComboBox, dtpctl As DateTimePicker Dim chkctl As CheckBox Dim typ As String For Each ctl In Me.pnBottom.Controls typ = ctl.GetType.Name If typ <> "Label" Then ctl.DataBindings.Clear() Select Case ctl.Name.Substring(0, 3) Case "cbo" cboctl = ctl AddHandler cboctl.SelectedValueChanged, AddressOf UpdateDG ctl.DataBindings.Add(New Binding("SelectedValue", DetailRow, _ ctl.Name.Substring(3))) Case "dtp" dtpctl = ctl AddHandler dtpctl.ValueChanged, AddressOf UpdateDG ctl.DataBindings.Add(New Binding("Text", DetailRow, _ ctl.Name.Substring(3))) Case "chk" chkctl = ctl AddHandler chkctl.CheckedChanged, AddressOf UpdateDG ctl.DataBindings.Add(New Binding("Checked", DetailRow, _ ctl.Name.Substring(3))) Case Else AddHandler ctl.Leave, AddressOf UpdateDG ctl.DataBindings.Add(New Binding("Text", DetailRow, _ ctl.Name.Substring(3))) End Select End If Next End Sub Basic idea of that is that it grabs each control name that I want to bind, determines the type by the first three letters of the control name, and then binds to the relevent field name (so I have, for example, a control called dtpTradeDate that binds to a field called TradeDate). The UpdateDG routine is designed to push the data back from the controls into the datagridview. That looks something like this... Private Sub UpdateFXSpotDG(ByVal sender As Object, _ ByVal e As System.EventArgs) Me.bm.EndCurrentEdit() End Sub And that, as I say, almost works. The problem that I'm running into is that not all of the controls update the datagridview correctly. Textbox updates are fine, but check boxes, combos and datetimepickers are a flaky. For example, if you click a checkbox in the detail section then the datagridview doesn't update. If you then click the checkbox a couple more times, it starts behaving itself. Similar things happen with datetimepickers and combos - combos especially where the style is set to DropDownList and you update it by tabbing to it and using the keyboard. I've tried using different events, but with no joy so far. Hopefully that makes sense. Any ideas out there? Tag: How to prevent window activation when tray icon clicked? Tag: 116424

 - Invoke does not change thread!? Hi, My complete scenario is a bit to complicated to explain, but my problem is this: I start a child-thread from the main thread, the child is not a BackgroundWorker, but a Thread, since it needs to be in ApartmentState.STA because it needs to create a Form and display some stuff. It all works pretty well, unless an exception occurs in the child thread. The application shows the standard error dialog to the user, and I don't want that. If an exception occurs, I want to get (at least) the exception message over to the main thread, and display it there. To accomplish this, I catch the excepion in the child thread, and does an Invoke call with the string message, to the main thread. The problem is, it does not switch to the main thread, it's always the child (using the threads-window in VS to see that)! Very strange, what might I be doing wrong? regards Carl Tag: How to prevent window activation when tray icon clicked? Tag: 116403

 - Win Form never gets focus?!? Hi all, In my winform application, I want to check on certain moments if my winform has focus. If so, some code will be executed. I noticed however, that the winform never gets the focus, even when it clearly has focus. How is that possible? What setting could I've messed with that causes my winform never to get focus, even when activated? void Form1_Activated(object sender, EventArgs e) { // always returns 'False' in my project (when I test // in new project, it returns 'True' however!!) Console.WriteLine("ACTIVATED & " + "this.Focused = " + this.Focused); } Thanks in advance for your answers. Frederik Tag: How to prevent window activation when tray icon clicked? Tag: 116399

 - System.Diagnostics.Process Hi all, How do I call my windows application from a windows service project ? My solution consists of a windows project, a service project, a setup project and 2 class projects. After installation, my output produces all the relevant files in a folder "Install" on my c: drive. I got the code which doesn't produce any output... public partial class Service1 : ServiceBase { protected override void OnStart(string[] args) { System.Diagnostics.Process proc = new System.Diagnostics.Process(); proc.StartInfo.FileName = @"C:\Install\Test1.exe"; proc.StartInfo.CreateNoWindow = false; proc.StartInfo.WorkingDirectory = @"C:\Install\"; proc.EnableRaisingEvents = true; proc.Start(); eventLog1.WriteEntry(proc.StartInfo.FileName); } } I want the Service1 to call my Test1.exe file (which will be installed into the same folder), and run it. Is it possible to do that ? If not then how should I approach the issue ? Thanks for replying. regards, Andrew Tag: How to prevent window activation when tray icon clicked? Tag: 116398

 - How to launch an app with double-click on filename I have an Windows Form application that has child Forms in it. I have a constructor in the main form that takes a filename as an argument an creates a child form from the data in the file. If I launch the app from the command prompt with a filename as an argument, it works fine. But if I launch the application by double-clicking on the filename in Windows Explorer the child form is not created. I thought that double-clicking a filename was the same as using the command prompt with the file name as an argument at the point where the application is launched, but apparently this is not true. Do I have to handle the two situations differently in my code? Or do I do something at the OS level that will make this work as I thought it should?

 - Stopping a RichTextBox updating I am trying to do an operation where I find and highlight all instances of a string in a RichTextBox. E.g. pMatchesFound = Regex::Matches(pRichTextBox->Text, pStr, options); for (int i = 0; i < pMatchesFound->Count; i++) { Match ^m = pMatchesFound[i]; pRichTextBox->SelectionStart = m->Index; pRichTextBox->SelectionLength = m->Length; pRichTextBox->SelectionColor = SystemPens::HighlightText->Color; pRichTextBox->SelectionBackColor = SystemPens::Highlight->Color; } However the user sees the text scrolling through the RichTextBox as all the strings are highlighted, which isn't what I want. I've tried to prevent this with SuspendLayout but it doesn't work. Is there a way to stop the RichTextBox updating while I'm highlighting all the strings?

 - TableLayoutPanel and FlowLayoutPanel resizing question Hello, I have a 3-row table layout panel, each row of which contains a flow layout panel. For some reason getting the table and its children to auto-resize properly (and the flow panel's children to re-flow after) is proving difficult. Anyone have experience with this, or know of a thorough resource for information on resizing and anchoring controls? MSDN can be a little sparse with info at times.

 - FlowLayoutPanel clipping question Hello, I have a flow layout panel that I am programmatically adding a bunch of check box controls into. Everything works pretty well except when a check box control's label is wrapped to two lines. In that case a few pixels of the top and bottom of the label is getting clipped off, which is a little ugly. I'm going to see if there's a way of preventing wrapping, but that may not be a good solution, so anyone have any ideas on preventing clipping?

 - MDI and Form.TopMost Problem Hello Group, I am using .NET framework 2.0 I have a Windows Forms application. Using a menu item, I can set the TopMost property of the MDI-Parrent form to true. Works fine. I also have a "Windows menu". The menu has an entry for all open MDI windows automatically (set MdiWindowListItem to the menu entry). Works fine as well. Now the problem: if I have more than 9 windows open, only 9 windows are displayed on the menu, plus an additional item "more windows..". Selecting this item a window with a list box is displayed with all windows. The problem: if the MDI parent window has TopMost set to true, this window is displayed behind the MDI parent. This is especially a huge problem, if the MDI parent window is maximized, because then I cannot move the MDI parent window (the window in the background has the focus). The only chance a user has in this case is to use the Task Manager to kill the application --- which is never good for a commercial app. Does anybody have an idea? What I would need is kind of a hook so I can do something before the window with the list of windows is displayed.

 - DataGridView column sorting glyph not shown Hello, I am using a DatGridView in virtual mode and unbound data where i listen for CellValueNeeded events to fill the grid with data. I also want to sort the data by pressing on the columns which is why i listen to ColumnHeaderMouseClick as well. It works fine, but the problem is that the sorting glyph (i.e. the sorting order triangle image) is not visible on the column header if the column size is too small. I have tried all the AutoFill options available for the column size/width but none of them seem to be working. The sorting glyph "length" is simply ignored and column width is not adapted to include to glyph (i have to manually resize the column size to see the glyph). Is there any automatic way of handling this or do i have to calculate the column width manually by taking into consern the column header text length, font size and so on?

 - TypeConverter for object type Properties I have a property with a member of type object. I am showing the value of this property in a PropertyGrid but depending on the type of the object I want to use the correspondant TypeConverter. Here is an example of what I mean: public byte[] Test { get { return new byte[100]; } } public object Test2 { get { return new byte[100]; } } If I have both properties in a property grid, Test will be shown as an expandable item with the text "Byte[] Array".. if I expand the item I will be able to see all of the elements in the array. However, Test2 will only show the text "System.Byte[]" and I will have no way of reading the elements of the array. Of course the property of type object will not always contain a byte[].

 - Cascade non-MDI Forms I have code that cascades multiple forms that belong to my application. They are not MDI so my understanding is that the accepted method is to call CascadeWindows in user32.dll and use the desktop as the owner window. The problem is that it's un maximizing all other windows regardless of whether or not I pass their window handles to the method. Is there another way to do the cascade that doesn't have this side effect? I know I could just change all the locations. But it's the algorithm for determining the window size and z-order that I'm not yet comfortable re-writing. Any help is appreciated.

 - Controls in TablelayoutPanel not getting arranged properly Hi, I am programmatically creating a TableLayout panel with 8 columns and 21 rows . Within the cell I am placing some labels and checkboxes . Then I dynamically add more rows , by calling my function UpdateTable( ). private TableLayoutPanel tb = new TableLayoutPanel (). private void UpdateTable( ) { tb.SuspendLayout() ; tb.GrowStyle = TableLayoutPanelGrowStyle.AddRows; // assume LastRowCount = 21 , as I have added 21 rows earlier // hence I increment LastRowCount in the for loop initialization for( int i = LastRowCount+1 ; i< 20 ; i++ tb.RowStyles.Add( myRowStyle ); tb.ResumeLayout(false ); } Strangely enough the following things happen 1) Calling UpdateTable() for the first time - Only one row gets added ; 2) Calling UpdateTable () for the second time - The checkboxes are getting redrawn in DIFFERENT positions ... which is not desired . For the second one, I think pending layouts are getting performed intenally by the layout engine ... Can anyone help me in getting answers to these problems .

 - Can't get ComboBox to show that it has focus I have a WinForm with many text boxes and several combo boxes. I also have a toolstrip with cut, copy, and paste icons. When a user clicks one of the buttons (cut/copy/paste), I want to get the current active control and if it is a textbox or a combobox, to then copy the selected text to the clipboard (or do the appropriate option based on the button). I can get all of this to work just fine with the textboxes. To figure out the active control, I am using the GetFocus() pointer from "user32.dll". This is the only way I could find to do what I needed to do. Below is an example of how my code looks. [DllImport("user32.dll")] public static extern IntPtr GetFocus(); private void btnCopy_Click(object sender, EventArgs e) { FocusControl = Control.FromHandle(GetFocus()); if (FocusControl != null) { if (FocusControl.GetType().ToString() == "System.Windows.Forms.TextBox") { TextBox myTextBox = (TextBox)FocusControl; if (!string.IsNullOrEmpty(myTextBox.SelectedText)) { Clipboard.SetText(myTextBox.SelectedText); } } else if (FocusControl.GetType().ToString() == "System.Windows.Forms.ComboBox") { ComboBox myComboBox = (ComboBox)FocusControl; Clipboard.SetText(myComboBox.SelectedText); } } } This works great for textboxes, but if the focus is on a combobox, the FocusControl object is null, so it doesn't fall into the if statement. I've tried using the ActiveControl method, but couldn't figure out how to drill down to the actual control that had focus. All it gave me back was the control that the textbox was on, not the actual textbox control. I'm sure I could iterate through each child control, but I figured there had to be an easier way. Any help would be greatly appreciated. Tag: How to prevent window activation when tray icon clicked? Tag: 116320

 - How to write IExtenderProvider control for .NET CF? Hi, I searched all over the net and I can't find no info how to do this, other then this post http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=158930&SiteID=1. I would like to rewrite this example http://msdn2.microsoft.com/en-us/library/system.componentmodel.iextenderprovider.aspx for Compact Framework, and I would like to do it VS2005 way. VS2005 suggests to use .xmta file which will produce *.PocketPC.asmmeta.dll file. The article I found also suggests to create yet another library where the designer would be. Does this mean that now instead of distributing two libraries (one for runtime one for design time) I have to distribute three (an extra *.PocketPC.asmmeta.dll)? I have a hard time to believe it. Can anyone shed some information on this? Thank you. Rastio. Tag: How to prevent window activation when tray icon clicked? Tag: 116318

 - Best practice for saving objects owned by objects Let's say that I have a class called Customer and a class called CustomerAddress. Now, further suppose that the Customer class has a property called _CustomerAddresses, which is List(Of CustomerAddress). Now, there's a form to edit a Customer, on which the user can click on a SAVE button to save changes, or on a CANCEL button to cancel any changes that they have made. In addition, on the Customer form, the user can make changes to the different CustomerAddress's that belong to the Customer (i.e. add, edit, remove). A separate form is used for adding or editing a CustomerAddress. For example, the user could select a CustomerAddress, in a grid, and then click on an EDIT button, at which point the Customer Address form is shown modally. On the Customer Address form, the user can also click on SAVE or CANCEL. Now, here's where the question comes in. The way that I am implementing this is that, if the user clicks on CANCEL for the Customer, any adds, edits, or deletes of CustomerAddress records associated with that Customer are disregarded/discarded. Is this the "usual" way to implement functionality like this? Tag: How to prevent window activation when tray icon clicked? Tag: 116315

 - Problems with UNICODE Characters for superscript 4,5,6,7,8,9 Hi, We have an application that has its own character map. Everything is working fine until yesterday. We got a new requirement which was to add superscript numbers from 0-9. Numbers 1,2,3 are display correctly. The issue is the 0, 4-9. With those characters I got the square on my Rich Text Box. The funny thing is, if I copy/paste one of them from Windows Character Map, after that all character will work using our character map. The way I'm passing the characters from our C.M to the Rich Text Box is the follow: Clipboard.SetText(CType(sender, UIButton).Text, TextDataFormat.UnicodeText) and Me.m_CurrentRTB.Text = Clipboard.GetData(System.Windows.Forms.DataFormats.UnicodeText) Does anyone had this issue before?

I have added the Design Time Properties for the designer to select the DataSource and DataMember, those seem to work fine at Design Time. But at Run Time the TextBox remains empty. How do I "Wire Up" the DataSource/Datamember so that the data shows in the TextBox?

 - Document.GetElementsByTagName(...) returns no elements I have C# .NET 2.0 code that behaves incorrectly only when run on one Windows Server 2003 (32 bit) machine with .NET 2.0 installed. And then, only the first time. And then, only when run from a CDrom. It will not fail on the local disk or network share. I have a WindowsForms application with a WebBrowser class on a form. In the DocumentCompleted event, I do... HtmlElementCollection divTags = webBrowser1.Document.GetElementsByTagName("div"); These documents are static docs loaded from the application directory. The document which has the DIV tag is loaded and the collection shows a count of zero the first time it is run on this machine from a CDrom. After that, it finds the DIV tag everytime. If I reboot, we are back to not finding it the first time. Right before the GetElementsByTagName() method, I dumped the Document.Text to the log file - indeed, there is the DIV tag. Any ideas?

 - WPF Data binding & Threading Dear reader, Im having a threading problem using WPF data binding on a custom dependency object with a clr object as data source and trying to update the data source from another execution context. The data source consists out of a simple class which implements the INotifyPropertyChanged interface. <code> // The clr object used as a data source. public class MyDataSource : INotifyPropertyChanged { private string _data; public MyDataSource(string info) { _data = data; } public string Data { get { return _data; } set { _data = value; this.NotifyPropertyChanged(value); } } private void NotifyPropertyChanged(string data) { if (this.PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(data)); } } public event PropertyChangedEventHandler PropertyChanged; } </code> The custom dependency object exposes one dependency property which I want to bind to the Data property of the data source. Below the code for illustration: <code> // the custom dependency object. public class MyCustomObject : DependencyObject { public static readonly DependencyProperty DataProperty = DependencyProperty.Register("DataProperty", typeof(String), typeof(MyCustomObject), new PropertyMetadata(String.Emoty, new PropertyChangedCallback(OnPropertyChanged))); public static void OnPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { MyCustomObject obj = (MyCustomObject) d; Console.WriteLine(String.Format("Property '{0}' changed; OldValue '{1}', NewValue '{2}'.", e.Property.Name, e.OldValue, e.NewValue)); } public MyCustomObject() { } public string Data { get { return (string)this.GetValue(DataProperty); } set { this.SetValue(DataProperty, value); } } } </code> And finally the binding definition: <code> MyDataSource dataSource = new MyDataSource("Hello World!"); MyCustomObject customObj = new MyCustomObject(); Binding binding = new Binding("Data"); binding.Mode = BindingMode.OneWay; binding.Source = dataSource; BindingOperations.SetBinding(customObj, MyCustomObject.DataProperty, binding); ... // Causes the dependency property to change. dataSource.Data = "Greetings World!"; </code> The above code works fine. But when I try to update the "dataSource" object from a WCF service callback (duplex mode) it doesn't update the dependency property. I think it as something to do with the execution context being different. Can anybody shed some light on this matter and explain me why this binding doesn't work this way and maybe come up with a solution. I'm running the above code within a console application (STA) compiled with the .NET Framework 3.5 version in Visual Studio 2008. Kind regards, Alex Koning.

Hello,

I have tray icon application I'm planning to develop in C# .Net 2.0.

What I want to do is have it so that when it is clicked, the current active
window will not be changed. The idea is that I want to get a clock event
but prevent windows form taking activation from the current window (Word,
IE, whatever.)

Is this possible? If not, can I at least get the window handle of the
window that is losing activation?

My application is a tray based dialer that wants to be able to sendkeys a
clipboard copy request to the active application so I can then pull the
selected text out in my application and use it to place a call. That is
what I'm working towards.

Thanks!
