    - How to cancel Ctr+Tab on TabControl? I'm building an Wizard style Win Form application. And am using TabControl to design and run the subsequent pages (actually 6 pages to finish the Wizard). Because it's an Wizard application, it shouldn't allow user to go next page while required text boxes are blank. To accomplish this, I timidly examine such required fields and then control the NextButton.Enabled property in each pages. I know it may not be a smart way but is the only way known by me now. My wizard works fine excepting one point. TabControl itself has built-in Short Cut Key feature which changes the current TabPage by CTR+Tab key. I want to cancel this short cut event but don't know how. How can I cancel such key event? Please help me. TK Tag: VB.NET Error with DLL Tag: 74809

    - 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: VB.NET Error with DLL 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: VB.NET Error with DLL 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?

    - 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: VB.NET Error with DLL Tag: 74726

    - 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.

    - ComboBox.SelectedText always returning empty string Hi all, I know I must be missing something very simple here, but this little problem is baffling me. If you have a combobox called cmbMyCombo and add a bunch of strings to it, say, "Apple", "Pear" and "Orange", and then call the cmbMyCombo.SelectedIndex it will tell you the index of the item that was selected. However, you would think that if you called cmbMyCombo.SelectedText it would give you the TEXT of whatever was selected (i.e. Apple, Pear etc), but all it does is return an empty string. Does anyone know why this is? Dano Tag: VB.NET Error with DLL Tag: 74659
