ah.. sige po... salamat sir..^^
ahm, tanung ko lang po, anu na po ba pinagkaiba ng visual basic 2008 sa vb.net..??
parang mas trending kasi yung vb.net, nakakaintriga lang po..XD
hahahaha..
anyways, salamat po ulit sir knives645, and specially sa thread na ito..^^
------------------------
by the way sir, panu po ba aayusin pag nakaencounter ka ng error about sa database,
di ko na po maalala yung error, pero alam ko po about sya sa same data na nilagay ko,
nagtry po kasi akong gumawa ng application na my ID, bale nung first na try ko, nagsave naman yung data,
nung second try ko naman na same parin yung ID na nilagay ko, yun po, nagkaerror na,
panu po ba yun.??

VB.net? Visual basic 2008?
Let me elaborate...
Microsoft release Visual Studio .Net, if I'm not mistaken that was 2002.
But prior to .Net merong visual studio 97 then visual studio 6.

Visual Studio is the IDE, same sa MS Office, it's a suite, it has Word, Excel, Powerpoint etc.
So sa Visual Studio, merong Windows Forms, WPF, SilverLight, ASP, etc.
Then meron kang languages na pwedeng gamitin like VB, C# and C++.

Yung 2002, 2003, 2005, 2008, 2010, 2012, 2013 and lastly yung 2014, versions lang yan ng Visual Studio.Net, parang android versions lang.

-from Sir Eric
Yung Visual Studio 6, includes VB6 is a WIN32 development tool
meaning ginagamit to create applications in the Windows32bit platform using native windows library.

VB.NET (VB2005 - VB2010) is a development tool to create applications running under the .NET Framework

So yung 2008 is version, while VB is the language.

With regards sa error mo,
Nag-declare ka ng Primary Key sa Table, so if you attempted to insert a duplicate ID, it will generate an error.
So you have to use Try/Catch to trap the error. Same to sa On Error Goto sa VB6.

Sabi ko nga nung una, lagyan mo ng Try/Catch ang code mo.
Or retrieve mo muna sa table mo kung meron kapareho ang ID.

Sample code using OLEDB, I didn't test the code, pero ganyan ang concept.
Code: 
Dim cmd As New OleDbCommand
cmd.CommandText = "SELECT count(*) FROM youTable WHERE ID = @ID"
cmd.Connection = conn
cmd.Parameters.AddWithValue("@ID", txtID.Text)

Dim oleRdr as new OleDbReader = cmd.ExecuteReader()
If oleRdr.HasRows = True Then
    oleRdr.Read()
    If oleRdr.Item(0) = 0 Then
        'ID is available and you can do insert command now
    Else
        'ID exists, notify user for duplicate entry.
    End If
End If

Yung NewStudentNumber mo ba, text or number?

Pa-try na lang pala na tanggalin ang space dun sa may [NewStudentNumber = ' " & txtStudentNunber.Text & " '"] ng SQL mo.

SELECT * FROM NewStudentList WHERE NewStudentNumber = '" & txtStudentNunber.Text & "'"

Like ko tong threds na to, pasilip baka may matutunan rin ako.. IT student rin ako.HEHE.. :D UP :) :) (peace)
 
Pahelp naman po paano ko ito icocode :(

kelangan po gagamit ng used defined functions eh absent ako nung tinuro di ko magets kasi nagaaral pa lang ako ng array :(

eto po yung problem:
Create 2 functions without parameters, one to display the word "YES" and one to display the word "NO" on screen in large letter using asterisks. Then, create a main function that will ask the user to enter a number. If the user will input an even number the program will call the YES function, otherwise it will call the no funtion.

Paano po yan? gagamit po ba ako ng if else if statement? Patulong naman po gumawa ng sarili function :(
 
mga sir..ptulong nman po.. bagong member lng po ako d2. bka nman po meron d2 na mrunong sa assembly langauage tnong ko lng po kung paano mag square root ng number tska po panu ung may option sa assembly language .ung kunware po pag run nyu ng program eh ang unang lalabas muna 2 option. ganito po oh. press A to compute adjacent, press O to compute for opposite ung gani2 po tapos pag nkapili ka na ng option eh magiinput kna ng number tpos cocomputin na nya .. EMU8086 po ang gamit ko na emulator sa assembly language.. tnx po
