I'm trying to do the very basic add "hello" to a button. The instructions tell you to click on the button the tutorials say the code that is supposed to show starts with "public class form1" but when I double click the button it seems to open the whole code of the template, not the button. (and no where in the code shows the "private sub button1_click")

I am using the DeviceXPlorer OPC Server V4.1.1.1 program to connect to the Omron PLC. I have made two programs, one is a form program which works fine, two is a windows service program where it does not let me connect to the OPC Server. The connection code is identical, the only difference is the windows service code is called by a timer. The timer works fines and jumps into the connection code, but stops at the line

I'm a rookie in Visual Basics 2008 and i am trying to make a program to communicate and read tags from an Omron PLC. I am trying to connect to the PLC via devicexplorer opc server, because it can let me read DInts and Reals from the PLC tags. I have referenced Microsoft ActiveX Datas Objects 2.5 Library and OPC DA Automation Wrapper 2.02. I have made some code which connects to the PLC "in a form", but I cannot use the same code and connect through as a Windows Service program.Here is my code,
Public Sub OpcConnect(ByRef Items() As String, ByVal PLCType As Integer)
Dim j As Integer
Dim TempSvrHandles As Array[code].....
Note: this code is run in a timer on the windows service, it connects properly to the "RSLinx OPC Server", but "Takebishi. Dxp.1" (devicexplorer shortcut) exits the sub routine at MyServer.Connect(PLCServer) ' connect to the opc server.

View 2 RepliesIntroduction[INDENT]Since this is my first thread in VB.NET forum(most of the time, I was in C/C++ forum), I want to share something that you might find it useful with your school project or with your works.Button is already a MUST-HAVE element in every program (I couldn't imagine program without a single button would function). Because it is everywhere, its appearance affects your form's appearance greatly. Some people might not care about how their software looks, but to me, it is a very important aspect for my software.

I haven't touched VB or Visual Studio in an incredibly long time, so I appologize if this sounds ignorant.
Right now, my application (pictured below) is a simple button that executes a shell command. I was thrilled that I even managed that, but it got me to wondering if my application could execute that command, rather than sending the process to cmd.exe.
When executing a click event on a button is there a way to know if a user has clicked or if code has executed it by a performClick in the sub that handles the click event. Maybe a change in the sender?

Are there any free or cheap Code coverage tools I can use "ad hook" just to run my program and see wich methods that is not runned in the project for that session? Im not interrested in tools that has to use unit-tests or a lots of advanced functions. If possible just "hit'n run".Its for a "fun" event in a "programmer pentathlon". I'll get 10 programmers run a program and the person that cover most code when running it will win.
