I made this thread for all programmers starting their adventure in VB.NET.

Please post relevant and sensible questions regarding VB.NET,
share your knowledge and expertise, share codes and techniques.

Post question on HOW TOs:
How to do this or that, ill supply bits of code to accomplish basic tasks.

Ill be posting series of samples leading to complete applications,
your suggestions are encouraged.
These samples will contain codes relevant to other tasks as well.

Platform = VS2003 to VS2012

i suggest learn and get the feel of VB.NET/VISUAL STUDIO IDE first before posting questions,
so that we can talk on the same page.


Topics:
VB.NET Winforms (not Web Applications)
ADO.NET as applied in VB.NET
Crystal Reports on VB.NET
SQLServer as used in VB.NET
MSAccess as used in VB.NET
Classes
UserControls

Technologies:
Serial - like using SMS, Barcode and other hardware
TCP/IP - chat applications, sockets, internet applications
MSMQ - message queuing
Remoting - executing assemblies in other computer
WebServices - using webservices in windows forms
Multithreading - executing more than 1 process at the same time


Suggested Third Party Tools:
DevXPress 2009 Free Edition
SQLServer 2005 Express Edition

Suggested references:

http://www.java2s.com/Tutorial/VB/CatalogVB.htm

I currently use Visual Studio 2008 only, but basic codes will apply to all versions

Please do not ask for a complete system,
instead use the codes and assistance that you will find here
to build your own system.


***Thanks to moderators, STICKY na ang thread!

Lets share knowledge so that we can be a more flexible and well rounded programmer. Be it for school or work.

hi mga sir, pano po ma view yung 5 tables from ms access sa isang(1) datagridview (by that I mean 1 datagridview in 1 form), sa VB.net 2015?? salamat po sa tutulong

 

[cyber6580]

Patulong naman po mga master sa VB.Net basic lng alam ko and self study lang. Meron ksi ako ginawang simple program para makapagscan ng barcode. Working naman for more than 1 year na. Ang problem ko lang is pag nagpapalit sila ng server need ko update ung connection string nya sa source code kasi hardcoded dun yung db access credentials. Naisip ko gumawa ulit ng isang apps para dun i enter ung db credential, yung mga value na ininput dun ang kukunin ni main application para sa connection nya sa database. Pano kaya gagawin un?

sa tingin ko merun kang 2 option para jan... first option save mo sa registry yung server credentials encrypt mo na lang yung sensitive info kung gusto mo, yung second option gawa ka ng table sa server for credential lang, mas Ok to kasi pwede maaccess ng program mo yung server as long as nakakaconnect sa server yung pc na magrurun ng program mo.

Try to use sql join mas madali kasi yan at mabilis sa pag process.
