I. How to Set proxy IP Address

Public struct Struct_INTERNET_PROXY_INFO
{
Public int dwAccessType;
Public IntPtr proxy;
Public IntPtr proxyBypass;
};

[DllImport ("wininet. dll", SetLastError = true)]
Private static extern bool InternetSetOption (IntPtr hInternet, int dwOption, IntPtr lpBuffer, int lpdwBufferLength );

Public static void RefreshIESettings (string strProxy)
{
Const int INTERNET_OPTION_PROXY = 38;
Const int INTERNET_OPEN_TYPE_PROXY = 3;
Struct_INTERNET_PROXY_INFO struct_IPI;
// Filling in structure
Struct_IPI.dwAccessType = INTERNET_OPEN_TYPE_PROXY;
Struct_IPI.proxy = Marshal. StringToHGlobalAnsi (strProxy );
Struct_IPI.proxyBypass = Marshal. StringToHGlobalAnsi ("local ");
// Allocating memory
IntPtr intptrStruct = Marshal. AllocCoTaskMem (Marshal. SizeOf (struct_IPI ));
// Converting structure to IntPtr
Marshal. StructureToPtr (struct_IPI, intptrStruct, true );
Bool iReturn = InternetSetOption (IntPtr. Zero, INTERNET_OPTION_PROXY, intptrStruct, Marshal. SizeOf (struct_IPI ));
}

Ii. Determine whether the web page is loaded by webBrowser

Private int _ IsLoadedCounter = 0;

This. webBrowser1.Navigated + = new

System. Windows. Forms. WebBrowserNavigatedEventHandler (webBrowser1_Navigated );

This. webBrowser1.DocumentCompleted + = new WebBrowserDocumentCompletedEventHandler (webBrowser1_DocumentCompleted );

Private void webbrowserappsdocumentcompleted (object sender, WebBrowserDocumentCompletedEventArgs e)
{
This. _ IsLoadedCounter --;
If (this. _ IsLoadedCounter <= 0)
{
This. Text = "success"; // Loading completed
This. _ IsLoadedCounter = 0;
}

}

Private void webbrowserinclunavigated (object sender, WebBrowserNavigatedEventArgs e)
{
This. _ IsLoadedCounter ++;
}

3. How to set and obtain the position of the webBrowser scroll bar

4. If you set the mouse position and double-click

Class Library

Public static readonly int MOUSEEVENTF_LEFTDOWN = 0x2;
Public static readonly int MOUSEEVENTF_LEFTUP = 0x4;
Public static readonly int MOUSEEVENTF_MIDDLEDOWN = 0x20;
Public static readonly int MOUSEEVENTF_MIDDLEUP = 0x40;
Public static readonly int MOUSEEVENTF_MOVE = 0x1;
Public static readonly int MOUSEEVENTF_ABSOLUTE = 0x8000;
Public static readonly int MOUSEEVENTF_RIGHTDOWN = 0x8;
Public static readonly int MOUSEEVENTF_RIGHTUP = 0x10;

[DllImport ("user32.dll")]
Public static extern int GetCursorPos (ref PONITAPI p );

[DllImport ("user32.dll")]
Public static extern int SetCursorPos (int x, int y );

[DllImport ("user32.dll")]
Public static extern int mouse_event (int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo );

Set the IE scroll bar position

This. webBrowser1.Document. Window. ScrollTo (scrollx, scrolly );

Set the mouse position

MouseControl. SetCursorPos (pointx, pointy );
Double-click

MouseControl. mouse_event (MouseControl. MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0 );
MouseControl. mouse_event (MouseControl. MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 );
