There is no "simple" guide to multi-threaded coding. You just have to do a bunch of research on the subject, write little test apps to verify what you're thinking is correct, and teach yourself this stuff. I can't tell you how to do threading is a forum post. There's just too much information.

Open the MSDN Library and check BackgroundWorker,
there are good examples there. We are here to help, not to teach.

Yes.
But probably not in the WinForms forum.Opacity, the new Transparency.

DirectorySearcher Searcher = new DirectorySearcher(Entry);
Searcher.SearchRoot = Entry;
Searcher.Filter = "(&(objectClass=user)(sAMAccountName=" + UserName + "))";
Searcher.PropertiesToLoad.Add("cn");
Searcher.SearchScope = SearchScope.Subtree;

on menu click i am opening the purchase form and vedor form.i want that when i open vendor/purchase form
the previously opened form get closed..
private void addNewVendorToolStripMenuItem_Click(object sender, EventArgs e)
{
Vendor frm = new Vendor();
frm.MdiParent = this;
frm.Show();
}
private void purchaseToolStripMenuItem1_Click(object sender, EventArgs e)
{
Purchase frm = new Purchase();
frm.MdiParent = this;
frm.Show();
}

Before "frm.Show();", add "this.Hide();"
Unless you are looking for a modal window that blocks the old window,then I think you change "frm.Show();" to "frm.ShowModal();"Opacity, the new Transparency.

Really, it is just a user drawn tab control turned on it's side.
The ball with LEDs is just an image with transparency that is in front of the tab control.
Don't mistake flashy graphics for new functionality.
There are articles here on transparency, odd shaped controls and user drawn controls.Opacity, the new Transparency.

I am trying to set a .NET WinForms Control as a child to a Window/Form residing on another thread or in a different process altogether. I have had success in parenting a .NET WinForms Control to a native Win32 window in a separate process as well as a .NET WinForms Control to .NET Form residing in another process. However, when I do such to a .NET Form, the .NET form throws several exceptions when it is trying to paint the parent form. If I let the debugger catch and continue after each exception (a real "no no"), the child control finishes painting and the parent Form is left undrawn, with a big red "X" drawn in the background. Only when I create a custom UserControl and set it to the remote .NET Form does it work. What is wrong with the underlying paint procedures of several other controls in the .NET Framework for me to get this inconsistant behavior? Sample code is below...
.NET Control on a native Win32 window - WORKS FINE
// Create any WinForm control
Button button = new Button();
// Set the parent window of that control (aka window) to a common
// native Win32 window...in this case the Desktop window
Win32.SetParent(button.Handle, Win32.FindWindow("Progman", null));
// Continue running the message loop
Application.Run();
.NET UserControl on a Remote .NET Windows.Form - WORKS FINE
// Create a custom UserControl (set colors so you can see it. the
// standard UserControl has the same colors as the Form's background)
UserControl1 ctrl = new UserControl1();
// Set the parent window of that control (aka window) to a common
// .NET Form...in this case the Form1
Win32.SetParent(ctrl.Handle, Win32.FindWindow("WindowsForms10.Window.8.app.0.378734a", "Form1"));
// Continue running the message loop
Application.Run();
.NET Control on a Remote .NET Windows.Form - DOES NOT WORK
// Create any WinForm control
Button button = new Button();
// Set the parent window of that control (aka window) to a common
// .NET Form...in this case the Form1
Win32.SetParent(button.Handle, Win32.FindWindow("WindowsForms10.Window.8.app.0.378734a", "Form1"));
// Continue running the message loop
Application.Run();

If the form & control creation threads are different, then the event on the other thread have to be invoked. Adding a child control from a different thread fires events on the new parent thread that should be invoked. Obviously, you don't have control of the firing to make them invoked, so crash and burn.
The child draws fine, the parent, needing invoke, crashes.Opacity, the new Transparency.

When I began testing, that was my assumption going in. However, of the three code snipplets I posted, two work fine, which seem to counter your explaination. A .NET control parented to a native Win32 window in a separate process works fine as well as a .NET "UserControl" class being parented to a .NET window in a separate process. Only in select cases does your explaination seem to hold weight. Try my examples and see what you get.
