    - using DesignSurface in the 2.0 framework. Is there any documentation on how to use the new DesignSurface that is available in the 2.0 beta? I'm having problems figuring out how it works. I can add controls to it, and I can retrieve an ISelectionService for the controls, but it doesn't fire any events if I hook up to the SelectionChanged event and click on my added controls.

    - MSVDM messing up dynamic TabControl? I have a TabControl (named Tabs) that shows search results. When the result set changes, I do Tabs.Controls.Remove() to remove all but the first TabPage, then I (maybe) create new TabPage-s. Works fine - except when I switch desktops with MSVDM and then come back: Then, next time I delete / recreate, I only get the tab buttons for the new pages. Clicking the button hides the first tab, but then the new tab never comes up. (I can bring up the first (non-dynamic) tab, but not any of the others.) I've tried various things, like setting EVERY property that the form designer sets and/or explicitly disposing of the tab pages (and their controls) instead of just Remove()ing them. Haven't found the ticket, yet, and Google turns up nothing. Are there known issues with the TabControl (or z-order in general) and MSVDM? Work-arounds? -- programmer, author http://www.midnightbeach.com and father http://www.midnightbeach.com/hs Tag: TreeView CheckBox Tag: 74791

    - basic main form --> child form question Hi, I have an application with a main form (public __gc class MDIParent:public FormsAndHelpers::SelfPositioningForm). I have a menu item on that form that creates another child form (called CarrierRegionSwitchExplorer). I remember a pointer to the child form I create, in the Main form, like this: System::Void MDIParent::ShowCarrierRegionSwitchExplorer() { if (NULL == m_pCarrierRegionSwitchExplorer) { m_pCarrierRegionSwitchExplorer=new CarrierRegionSwitchExplorer; m_pCarrierRegionSwitchExplorer->ShowDialog(); } } m_pCarrierRegionSwitchExplorer is a static member of MDIParent, declared like this: static CarrierRegionSwitchExplorer *m_pCarrierRegionSwitchExplorer; When I close the CarrierRegionSwitchExplorer dialog, do I have to get rid of the child form object I created on the heap? If yes, then where I create an event handler to do it? I can't delete m_pCarrierRegionSwitchExplorer on an event handler for the "Closed" event for the CarrierRegionSwitchExplorer form, it sounds very wrong to me. Am I going about stuff the wrong way? Am I completed missing the "automatic" way .NET can do this for me? Any pointers are appreciated. Thanks, Vishnu Tag: TreeView CheckBox Tag: 74789

    - MVP please help - List box horizontal scroll bar I have a list box that uses the horizontal scroll bar. I would like to be able to "scroll" my headings at the top of the list box when the list box is scrolled. Spy reveals that this is not a real scroll bar (hwnd always null), so I can't see how to find out when, and how much, the list box is scrolled. If I create my own scroll bar, I have trouble keeping the display smooth. The best I can seem to do is to intercept and ignore the WM_ERASEBGND message, but the effect is still not nearly as smooth as using the ListBox.HorizontalScrollBar property. In addition, when I create a HScrollBar object and try to anchor it to the bottom of the list box, it moves when I vertically scroll the list box. I am reduced to repositioning it every time I receive a vertical scroll message. Obviously I would prefer to use HorizontalScrollBar, but I would settle for a decent looking scroll effect using HScrollBar. Can anyone help? Thanks in advance, Valerie Hough Tag: TreeView CheckBox Tag: 74786

    - Forms within one form I am trying to take a form and based on a selection from a list, it will open a form and bind it to the main form so it looks like one form. In VB6 you could do this using a few different 3rd Party controls, one was the Sheridan/Infragistics splitter control. You could bind a form to a specific pane of the splitter control. Does anyone know of a way to do this using .NET. Loren Tag: TreeView CheckBox Tag: 74778

    - ContextMenu - MVP please help Is there any reason why a ContextMenu object cannot be created (and populated with menu items) in the constructor of the control for which it will be used? If not, then why don't my mnemonics show up if I do it this way? (they work but don't show as umderlined) If I create the ContextMenu in my form and use the ShowMenu() function from my form, the mnemonics will appear properly. If I do have to do it from my form, then I also have to process MouseUp() in my control, then notify the parent form so that it can display the ContextMenu (obviously not what I want to do, nor would it seem that this would be Microsoft's intended behavior) Please help!

    - about Printing forms Hi; i want to print some controls on a form. I capture controls then draw them on print page. This is how i do it: http://www.dotnet247.com/247reference/msgs/5/26236.aspx now the problem is when i open a printpreview form, "generating previews" dialog box is shown first and if it is in front of a control to be printed, it is captured too. how can i avoid it? secondly, sometimes even if print page seems ok on the preview, images of the controls are distorted when i print them. what would be the reason? and another question, how can i print multiple pages? eg: i wanna put some controls on second page. There is HasMorePages property. i do not figured how to use it last question: what is the usual way when i want to print texts of many textboxes to prepare a report? thank you very much.

    - Default Form Button Focus Hello, This is a very trivial problem, however it is vexing me. Any help would be gratefully received. I have a form, with a textfield and a few buttons, the functionality I want to give the user is once they have finished typing their query in the text box, when the press return enter a default button (say submit) is pressed. However I can't get the button into focus so what they have to do currently is physically click on the button. Is there a way I can set focus on the button to automatically to accept the user pressing the enter key? Thanks Tag: TreeView CheckBox Tag: 74742

    - 2 different kinds of Maximize? When I have a standard windows forms Form, and I maximize it, it behaves just like you'd expect. It fills the screen, except for my taskbar down at the bottom of the screen (which has standard settings. The taskbar is locked, marked as keep on top of other windows, and set to not auto-hide.) When I have a windows form without a title bar though, and I maximize it, it fills the ENTIRE screen and the taskbar is not visible. I want to have a windows form without a title bar that maximizes but leaves the taskbar visible. Is this possible? How? Thanks, Steve Tag: TreeView CheckBox Tag: 74733

    - Windows Forms have layout problem with large fonts This problem started from the very beginning - when .NET Framework 1.0 is released. I have forms designed and tested on a Windows 2000 Pro system with large fonts (125%). They all look good until I run the exactly the same assembly on another system with normal fonts. The layout is messed up, especially those controls with the Anchor property set (other than the default values). I had expected Framework 2.0 would have solved this problem. But it had not - at least with the beta 1 release it had not do it. I am not sure if I am making my problem clear. Hope one of Microsoft guys can hear me and understand my problem.

    - ListBox, SelectedIndex, DataBind Issue This seems like it would be a common problem, so hopefully I am just doing something wrong. The attached demo code will help explain the problem. I simply want to have a text box in which I can type a value that will result in a ListBox being searched, and have the found item be selected in the ListBox. In the demo, I populate one listbox using DataBinding with a DataTable. In the other, I populate manually via the Items collection. When data binding is used, the SelectedIndex is manipulated in string ways. To see what I mean, do the following: 1. start the app (click ok on the messagebox). 2. enter "2001" in the databinding related field. 3. now hit the backspace key to delete the "1" in "2001". notice the SelectedIndexChanged event is fired twice. This does not happen in the non-databound scenario. If you set some breakpoints, and watch the call stack (with non-user code enabled), you'll see what is happening (but I don't know why). I've also used Reflector to review the ListBox code. I know the CurrencyManager comes into place when using DataBinding, but I'm still not sure what is happening. Any insight would be greatly appreciated. using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; namespace WindowsApplication4 { public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.TextBox textBox1; private System.Windows.Forms.ListBox listBox1; private System.Windows.Forms.TextBox textBox2; private System.Windows.Forms.ListBox listBox2; private System.Windows.Forms.Label label1; private System.Windows.Forms.Label label2; private System.ComponentModel.Container components = null; public Form1() { InitializeComponent(); LoadListBox1(); LoadListBox2(); } protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox(); this.listBox1 = new System.Windows.Forms.ListBox(); this.textBox2 = new System.Windows.Forms.TextBox(); this.listBox2 = new System.Windows.Forms.ListBox(); this.label1 = new System.Windows.Forms.Label(); this.label2 = new System.Windows.Forms.Label(); this.SuspendLayout(); // // textBox1 // this.textBox1.Location = new System.Drawing.Point(24, 40); this.textBox1.Name = "textBox1"; this.textBox1.Size = new System.Drawing.Size(96, 20); this.textBox1.TabIndex = 0; this.textBox1.Text = ""; this.textBox1.TextChanged += new System.EventHandler(this.textBox1_TextChanged); // // listBox1 // this.listBox1.Location = new System.Drawing.Point(24, 64); this.listBox1.Name = "listBox1"; this.listBox1.Size = new System.Drawing.Size(96, 173); this.listBox1.TabIndex = 1; this.listBox1.SelectedIndexChanged += new System.EventHandler(this.listBox1_SelectedIndexChanged); // // textBox2 // this.textBox2.Location = new System.Drawing.Point(168, 40); this.textBox2.Name = "textBox2"; this.textBox2.TabIndex = 4; this.textBox2.Text = ""; this.textBox2.TextChanged += new System.EventHandler(this.textBox2_TextChanged); // // listBox2 // this.listBox2.Location = new System.Drawing.Point(168, 64); this.listBox2.Name = "listBox2"; this.listBox2.Size = new System.Drawing.Size(104, 173); this.listBox2.TabIndex = 5; this.listBox2.SelectedIndexChanged += new System.EventHandler(this.listBox2_SelectedIndexChanged); // // label1 // this.label1.Location = new System.Drawing.Point(24, 8); this.label1.Name = "label1"; this.label1.Size = new System.Drawing.Size(96, 16); this.label1.TabIndex = 6; this.label1.Text = "DataBind"; // // label2 // this.label2.Location = new System.Drawing.Point(168, 8); this.label2.Name = "label2"; this.label2.TabIndex = 7; this.label2.Text = "Items Add"; // // Form1 // this.AutoScaleBaseSize = new System.Drawing.Size(5, 13); this.ClientSize = new System.Drawing.Size(292, 245); this.Controls.Add(this.label2); this.Controls.Add(this.label1); this.Controls.Add(this.listBox2); this.Controls.Add(this.textBox2); this.Controls.Add(this.textBox1); this.Controls.Add(this.listBox1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false); } [STAThread] static void Main() { Application.Run(new Form1()); } private void LoadListBox1() { DataTable dt = new DataTable(); dt.Columns.Add("year"); for(int i=2000; i<=2004; i++) { dt.Rows.Add(new object[] {i}); } listBox1.DataSource = dt.DefaultView; listBox1.DisplayMember = "year"; } private void textBox1_TextChanged(object sender, System.EventArgs e) { FindIt(listBox1, textBox1.Text); } private void LoadListBox2() { for(int i=2000; i<=2004; i++) { listBox2.Items.Add(i.ToString()); } } private void textBox2_TextChanged(object sender, System.EventArgs e) { FindIt(listBox2, textBox2.Text); } private void FindIt(ListBox b, string s) { int index = b.FindStringExact(s); if (index != -1) b.SetSelected(index, true); else b.ClearSelected(); } private void listBox1_SelectedIndexChanged(object sender, System.EventArgs e) { MessageBox.Show("ListBox1 SelectedIndex Changed"); } private void listBox2_SelectedIndexChanged(object sender, System.EventArgs e) { MessageBox.Show("ListBox2 SelectedIndex Changed"); } } } Tag: TreeView CheckBox Tag: 74726

    - How to add a custom control to a standalone .exe file (no extra .dll) Hi, I have created a custom control inherited from the combobox, and would like to use it on my windows application.

    - Hey, MS guys, advice is need for HelpProvider I want to display unicode characters in a HelpProvider's HelpString. I'm eagerly anticipating someone's oppinion about if this is possible, and if it is, how can i do it, because the cyrrilic characters that i enter as a value for the HelpString property get messed up when they are displayed. However, there's no such problem with tooltips, even though they seem to be using a similar mechanism. I had the idea of deriving from HelpProvider and overriding some of the functionality but as long as HelpProvider is from the Windows.Forms namespace it's source is not included in the SSCLI implementation of the framework, so i cannot taste it's inner workings. And guys, please skip answers such as "Don't multipost". Yes, i have posted about this before but as i'm posting again as long as no one paid attention to my previous post i go shooting the same question again becuase someone definetly has to know if there is a reasonable workaround for my problem or i have to manually implement some popping up rectangles with helpstrings.

    - DateTime values in DataGrid I am populating a DataSet using SqlAdapter and then displaying it in a DataGrid. Some of the values in the DataSet are DateTime. It seems by default they are displaying as dd/mm/yyyy and I want to also display the time. I have played around with the DataGridTableStyle and the DataGridTextBoxColumn but nothing seems to take affect. Is there a good resource that outlines how to use these classes or is their an easier way to go about things? -- Dan S Tag: TreeView CheckBox Tag: 74651

    - Exception with AsyncCallBack + Control.Invoke I posted it in the wrong newsgroup. So I have to repost it again. Sorry. I used Application.ThreadException event to handle all unhandled exceptions in WinForm application. However, when I start converting my application into asynchronous operation, I have faced with some problems. I used AsyncCallBack to do something when the operation finishes. However, as you might know, AsyncCallBack delegate will be called in a different thread from the activated thread (which is likely to be the thread that run the asynchronous operation). In certain cases, this delegate might throw an exception and I WOULD LIKE to have the Application.ThreadException to handle this exception. But I cannot do that since the current thread is not UI thread. So, the exception will just disappear. I also thought of a silly idea by calling Control.Invoke(ThrowAnExceptionForMe) but inside Control.Invoke, there is a try-catch block which will throw an exception back to the calling thread (which is not a UI thread). It would be nice if I can find a workaround for this without changing the way I handled the exception (I mean still depending on Application.ThreadException). Any suggestion?

    - How many touches does no touch deployment take? ERROR: Not Found Now I guess I am missing something very basic here, but it has now taken nearly a full week to get my app launched from a browser URL - and still I haven't succeeded. The error I am getting now when I launch the exe as a URL is 404: Not Found. But what isn't found???? 'ntmizar': Loaded 'dw9ryd7d', No symbols loaded. 'ntmizar': Loaded '2hulxqpj', No symbols loaded. 'ntmizar': Loaded 'c:\winnt\assembly\gac\system.enterpriseservices\1.0.5000.0__b03f5f7f11d50a3 a\system.enterpriseservices.dll', No symbols loaded. 'ntmizar': Loaded 'pr7x_hbw', No symbols loaded. 'ntmizar': Loaded 'lk0plth9', No symbols loaded. An unhandled exception of type 'System.Net.WebException' occurred in IEExec.exe Additional information: The request failed with HTTP status 404: Not Found. (This is displayed when I choose to debug) The EXE and one DLL ARE DOWNLOADED before the error occurs: 'ntmizar': Loaded 'c:\documents and settings\ciskac\local settings\application data\assembly\dl2\ngbqkna0.aoo\6d9dohkj.9oo\0482e537\80b95ef7_eb68c401\shu.f d.printunit.ui.exe', No symbols loaded.

BACKGROUND I can launch the app by URL from the development machine but not from several other PCs which all have the .NET framwork v1.1 installed. The windows forms application (exe) and support dlls have strong names and are all in the same directory on the webserver. I have configured security to Fully Trust everything from this URL. The app has been built in debug and release configurations and all files in the bin directory copied to the webserver. A config file is used and the web.config file has been modified to permit its download Between tests I clear the download cache using gacutil and the Internet Cache The webshare has been configured not to execute scripts Any pointers on this would be greatly appreciated.

    - is Disposed required for shared form ?? Hi, I have a Windows App which uses a custom form to display messages. This form is based on the singleton pattern so that the user does not need to explicitly create an object of this form. After the Showdialog() method on this form, do i need to dispose this form explicitly. i distinctly remember one article saying that all Modal forms needs to be disposed explicitly. This is the code snippet i am using: Public Class myMessageForm Private Sub New() 'new instance not possible End Sub private Shared frmMsg as MyMessageForm = Nothing Public Shared Function Display(ByVal text as String) as DialogResult If frmMsg is nothing then frmMsg = New MyMessageForm End If 'Set some properties Return frmMsg.ShowDialog() End Function Calling Code: If txtCustId.text.Length = 0 Then MyMessageForm.Display("Invalid Customer Id") End If Any help would be appreciated. TIA :) Tag: TreeView CheckBox Tag: 74644

I want to implement checkboxes in all child in a treeview EXCEPT all top
most root nodes.

TreeView control's CheckBoxes property implement this functionality to all
nodes or to none.
So is there some way to implement CheckBox to some specific node?

Thanks
