Introduction

This is a simple implementation of a TCP client server relationship.

To use

Compile the server and client programs separately. Before compiling change the IP address in both programs to match that of your machine (NOTE : to get your IP address run 'ipconfig' from the command prompt in Windows NT/2000 m/c's)

When the server program is run, it will indicate at which IP it is running and the port it is listening to. Now run the client program is run , so as to establish a connection with the server.

When a connection is established the server will display the IP address and Port from where it has accepted the connection and client will ask for the string which is to be transmitted to the server.

The server on reciept of the string will display it, send an acknowledgement which will be recieved by the client.

The client can be either run from the same machine as the server or from a different machine. If run from a different machine then a network connection should exist between the machines running the server and client programs

Introduction
Here I am me again, with other programming trick. VB doesn't provide any support to icons in the menus (VB 6 and previous). Then, to accomplish such task it is necessary to run over to calls native API of Windows.
Purpose
Some programmers say that that is unnecessary. But it is common the users they to use the toolbar in most of the cases. It is interesting that he can associate the menu options the entrances in the toolbar.

For an application to be easy to use, it should be the most friendliest possible and not to demand of the user, complex reasoning.

The people use computers to activate your tasks and to win time.

The road of the stones
The best way to accomplish this task, would be with a visual atmosphere. Where you could choose in the list of available menus the item of wanted menu and in other (parallel) the wanted icon (what is made by other tools).

However, I will teach the less friendly, however functional way of the you make it.

API
Collapse
Private Declare Function GetMenu Lib "user32" (ByVal hwnd As Long) As Long


Private Declare Function GetSubMenu Lib "user32" (ByVal hMenu As Long, ByVal nPos As Long) As Long
Private Declare Function SetMenuItemBitmaps Lib "user32"
(ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long, ByVal hBitmapUnchecked As Long, ByVal hBitmapChecked As Long) As Long

Const MF_BYPOSITION = &H400&

Code Piece

Collapse
Private Sub SetMenuIcon()
On Error Resume Next

Dim hMenu As Long

Dim hSubMenu As Long

Dim Ret As Long

'Get main menu ID


hMenu = GetMenu(hwnd)


'


'MENU FILE


'Get sub menu 0 (File items)


hSubMenu = GetSubMenu(hMenu, 0)


'set bitmap to menu item, by ordinal


Ret = SetMenuItemBitmaps(hSubMenu, 0, MF_BYPOSITION, iNew.Picture, iNew.Picture)

Ret = SetMenuItemBitmaps(hSubMenu, 1, MF_BYPOSITION, iOpen.Picture, iOpen.Picture)

Ret = SetMenuItemBitmaps(hSubMenu, 2, MF_BYPOSITION, iSave.Picture, iSave.Picture)

'Skip the separator (it's 3)


Ret = SetMenuItemBitmaps(hSubMenu, 4, MF_BYPOSITION, iSave.Picture, iSave.Picture)

'Skip the separator (it's 5)


Ret = SetMenuItemBitmaps(hSubMenu, 6, MF_BYPOSITION, iExit.Picture, iExit.Picture)

' The rest of the code was removed to maintain clear. See in the file 'ZIP the complete and functional example.


End Sub

The icon may be 14x15 pixels.

One can block the website by using the below tricks



Step 1: Click the Start button and select Run. Now type the following text in that Run box:

notepad c:\WINDOWS\system32\drivers\etc\hosts

Step 2: You will see a new notepad window on your screen containing some cryptic information. Don’t panic. Just goto the last line of the file, hit the enter key and type the following:

127.0.0.1 orkut.com
127.0.0.1 facebook.com
127.0.0.1 myspace.com

Save the file and exit. That’s it. None of the above sites will now open on your computer.

You can block as many websites as you like with the above technique. If you want to remove the ban later, open the same file as mentioned in Step 1 and delete the above lines.

Pretty simple but remember, our children are also very smart. And there are some popular ways to unblock websites.
