I need to disable "save as" file download dialog in webbrowser.

I found this way:

void ListenForDialogCreation()
{
    // Listen for name change changes across all processes/threads on current desktop...
    _WinEventHook = WinAPI.SetWinEventHook(WinAPI.EVENT_OBJECT_CREATE, procDelegate);
}
void StopListeningForDialogCreation()
{
    WinAPI.UnhookWinEvent(_WinEventHook);
}

void WinEventProc(IntPtr hWinEventHook, uint eventType, IntPtr hwnd, int idObject, int idChild, uint dwEventThread, uint dwmsEventTime)
{
    const uint OBJID_WINDOW = 0;
    const uint CHILDID_SELF = 0;

    // filter out non-HWND, and things not children of the current application
    if (idObject != OBJID_WINDOW || idChild != CHILDID_SELF)
        return;

    //Get the window class name
    StringBuilder ClassName = new StringBuilder(100);
    WinAPI.GetClassName(hwnd, ClassName, ClassName.Capacity);

    // Send close message to any dialog
    if (ClassName.ToString() == "#32770")
    {
        WinAPI.SendMessage(hwnd, WinAPI.WM.CLOSE, IntPtr.Zero, IntPtr.Zero);
        if (OnDialogCancelled != null)
            OnDialogCancelled();
    }
    if (ClassName.ToString() == "#32768")
    {
        WinAPI.SendMessage(hwnd, WinAPI.WM.CLOSE, IntPtr.Zero, IntPtr.Zero);
        if (OnDialogCancelled != null)
            OnDialogCancelled();
    }

}

public delegate void OnDialogCancelledEvent();
public event OnDialogCancelledEvent OnDialogCancelled;

But here using missing dll. Help me please.

This is where I found the code: How to block downloads in .NET WebBrowser control?

The only thing missing is the pinvoke wrappers, which you can either write yourself from the documentation (or use pinvoke.net for easy reference with cut&pastable examples), or use one of the wrapper libraries that exist (if you can find one that's compatible with your licensing needs).
