    - 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: Validating the form 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: Validating the form 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: Validating the form 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. It is written in C#. The problem is that I want to have my app on a single .exe file without having to attach the control's additional dll file (it is a simple tool that will be deployed as a standalone .exe application with no installation pack). I tried to add my customcontrol.cs code file to the project, then programmatically add the custom control instance to my form, but it will not show it in the GUI (even though I can see it is there in my properties window on the VS). Is it possible to add the control to my form without having to have an additional dll? Please advise. Best Regards, Uriel. Tag: Validating the form Tag: 74725

    - 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.

    - Making a form a child of a control In Delphi it's possible to make a form appear inside a panel control as a child subform by setting the form's Parent property to the instance of the control. When I try to do the same in .NET I get the error "Cannot make a top-level control a child of another control". It would really be a huge disappointment to find out that Windows Forms doesn't allow nesting of forms inside panel controls, so I hope I'm just not doing it right. Any suggestions?

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.

    - 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?

    - Problem with the Windows Forms Designer... I have a custom control called, lets say, SportBillyComboBox, which inherits from ComboBox. When I add my control from the toolbox, I get an error (System.NullReferenceException : Object not set to an instance of an object) on my form replacing the control, but my newly added SportBillyComboBox is there (even if "you can't see it" - under the Exception) and seems to work fine in compilation and in runtime. But when I next use the Windows Forms Designer to change or add something, it automatically adds those lines in the designer : this.SportBillyComboBox1.Items.AddRange(new object[] { ((object)(resources.GetObject("SportBillyComboBox1.Items"))), ((object)(resources.GetObject("SportBillyComboBox1.Items1"))), ((object)(resources.GetObject("SportBillyComboBox1.Items2"))), ((object)(resources.GetObject("SportBillyComboBox1.Items3")))}); Even if I never asked in the Designer to add some items in the collection, it magically appears in my InitializeComponent Code - TADAM! But worse of all, it doesn't add the necessary entries into my Form1.resx resources file so the code crashes on the newly automatically magically added line. Sure, I can always erase those lines, but every time I change something in my form, it add those lines again and again and again... Anyone having a fix for this one? Even my first problem (when I add the control to my form... the little "System.NullReferenceException" error) is disturbing! Do you have any clue?

When trying to get all the IE-windowd with the "For Each p In Process.GetProcessesByName("IEXPLORE")"-function, I only get 1 process returned, which has as "p.MainWindowTitle" the MainWindowTitle of one of the open IE-windows. Like that I'm not able to work with that IE-window I need. Does anybody how to get arroudn this problem? Is there a way to go directly by the Windows/Applications and not the Processes?

    - Bring another Window to Front Hi, My application has some interaction with an other application. I sometimes need to put the other application to the front. The problem is that I'm not able to get a nice solution to work in every case. I tryed two ways: one way it disn't maximazi the Windowd when it was Minimized, in the other way it resized the application when it was maximzed. First I take a Handle to the other Window with the "Process.GetProcessesByName("EXTRA")" and with the "Dim handle As IntPtr = Process.MainWindowHandle" First 'solution': SetForegroundWindow(handle) This gives me the problem with Mimized Window that gets the focus, but Second 'solution': ShowWindow(handle, SW_RESTORE) 'SW_RESTORE = 9 SetForegroundWindow(handle) This gives me the problem with the Maximized Window that is suddenly resized. What I actually need is a solution that works always: When the Windowd is Maximized, it has to keep Maximized. When it is Resized it has to stay Resized. When it is Minimized it should be Restored (to the last Status: Maxmimized or Resized). I found some stuff about the IsIconic-API, but it didn't seem to work. Does anybody knows a solution for my problem? I'm really stuck with it :-/ thanks a lot in advance, Pieter Tag: Validating the form Tag: 74634

    - Suppress ActiveX Control Warning in web browser control I'm writing a windows app in c# that can display offline html forms. The app uses the Microsoft Web Browser COM control. The offline forms our generated by another application. The offline html forms contain script code that saves the users inputs in an XML file on the client machine. This script code uses the wsh FileSystemObject and causes the web browser control to issue the warning "An ActiveX control on this page might be unsafe to interact with other parts of the page. Do you want to allow this interaction? Yes / No" Is it possible for my windows app to intercept this warning before it is displayed and return a positive response (i.e. the same as the user clicking 'Yes') ? I know the warning can be suppressed by setting the silent property to true (axWebBrowser1.Silent= true;) but this defaults the answer to false (i.e. the same as the user clicking no). Any suggestions would be appreciated. Thanks Andrew. Tag: Validating the form Tag: 74628

    - VS.NET-like interface: Docked Panels, Tabs, etc Hi, I want to give my application a Visual Studio .NET-liek interface: With Forms that can appear or disappear at the site like the Toolbox. With docked Forms. With Forms that are selectable with Tabs. I found some information abotu these stuff on the internet, but you always have to buy for it, or it is a dll. For security-reasons I'm not allowed to use dll's without having the source-code of it, So I can't use these things. (for exemple http://www.divil.co.uk/net/controls/dockingsuite/). Does anybody knows where I can find the (free!) source code for what I'm looking for? Any help our hints would be really apreciated! Thanks a lot in advance, Pieter Tag: Validating the form Tag: 74621

    - Problem with f.ShowDialog() Hi all When a child form is shown with ShowDialog, User can not click to ParentForm Until Child form is closed. It's normal. The problem occurs when My Child form has the following code: Private Sub Button1_Click(...)

After this, user can focus on Parent form and ca work with it. Does anybody know how to prevent this ? Thank you in advance. Tai Le Tag: Validating the form Tag: 74619

Hi,
When Validating event is raising on forms?
I know that Validating event is raising when focus is leaving the
control, but it seems that it is not the same in the case of forms.
For example, I can close the form or click on the other form in desktop
but nothing is happening.
Thanx, Cheya
