this is a function that can add a base url to all urls in an html page, this code was translated from this vb function displayed here :http://www.motobit.com/tips/detpg_replace-relative-links/

special thanks to the original coder...

the function (java) was tested and run successfully!

windows vista: access: local only

Ok, this is my first post of non programming issue but it still usefull for computers users.
Last week i got a new HP Laptop, with windows vista insite, it's cool looking, i was so happy with it untill i had the first problem, i couldn't surf the net.
well, i will not talk alot, because i guess some of you is reading here after a few days of searching.
well, what i had is like that:
i could connect to the network and see other computers but could not surf the net
that what you should do:
go to the network connection icon on the tray - > right click ->network and Sharing Center -> on the left press of the Manage network connection - > right click on the network that you want to log in to -> properties -> now you have some check boxes :
uncheck the Internet Protocol Version 6
stand on the Internet Protocol Version 4 and press properties :
check the Use the following IP Address :
and on the fields fill the following:
IP Address : [put an IP the is fine with your router]
Subnet mask : 255.255.255.0
Default gateway: the ip of your router

then check : use the following DNS server addresses
Prefered DNS server: the ip of your router.

press OK -> OK and restart your computer.

for me it worked..
thanks to the guys here: http://www.daniweb.com/forums/thread73818.html

sql query for getting your users email servers

this is a query that get you a list of the servers of the users emails that they registered with, for example if you have 100 people that has a hotmail account and 200 users with gmail you will get this table:
count server
-----------------
100 hotmail
200 gmail
...

here is the query:

select * from
(SELECT Count(users.UserID) AS Count, right(users.Useremail,len(users.Useremail)-instr(users.Useremail,'@')) as server
FROM users
where users.useremail <> ''
GROUP BY right(users.Useremail,len(users.Useremail)-instr(users.Useremail,'@')))
order by count

Selection.Find crash

you wrote an application that works with Word object?
the application crashes in the middle of the run, after the debug you find that it crashes on this line:
WordObj.Selection.Find

well, it's not your fault, it's a microsoft bug. now, how you resolve it??
it's a tricky way,
what you should do is late binding
u should dim your word object as an General object and create it manualy, not by "new word"
here is a usefull code:
...

Dim wrdDoc As Object  ' setting the word object as a general object
Dim IsWordRunning As Boolean

IsWordRunning = ApplicationIsRunning("Word.Application")
If IsWordRunning = True Then ' do
   Set wrdApp = GetObject(, "Word.Application")
Else
   Set wrdApp = CreateObject("Word.Application")
End If
wrdApp.Visible = True
Set wrdDoc = wrdApp.Documents.Open(filename)

...


and here is the applicationisrunning function:

Function ApplicationIsRunning(ApplicationClassName As String) As Boolean
' returns True if the application is running
' example: If Not ApplicationIsRunning("Outlook.Application") Then Exit Sub
Dim AnyApp As Object
 On Error Resume Next
 Set AnyApp = GetObject(, ApplicationClassName)
 ApplicationIsRunning = Not AnyApp Is Nothing
 Set AnyApp = Nothing
 On Error GoTo 0
End Function

adding adsense to phpbb 3 forum

do you want to add adsense advertising to your forum.
i could add adsense to the top of my forum by adding the code in the overall_header.htm file, i added it at the end of the file.
the important thing is that when i added it to the file manulay and then uploaded the file it didn't work, i succeded only when i changed the file through the admin system.
same i did with the google analytics code, i added it to the same file, but after the header tag.
if someone could do that after the first post only please write it here.

Beta Version for arabic language Google Adsense

Lately the google adsense for content started to support arabic language websites, the www.arabsites.co.il website administrator said that his site is utf-8 incoded and two weeks ago he started to show ads in his site, more he said, the pay per click still low, it's about 1-2 centes per click, but i guess when the time pass, more advertisers will know about the service and they will pay beter for a click.
the first report was on the arabic seo forum www.seoarabia.com
