Support Questions / Exit Button on MainMenu

« on: April 30, 2024, 11:11:11 AM »

I realize this may be a VS question rather than Advanced HMI, but I am a rookie so bear with me.

I developed an application first using the MainForm, OPC driver, it worked well with an AB emulator. I added a FormChangeButton to Page2, put an OPC driver there and page2 controls also worked fine. I put a FormChangeButton on Page2 back to the MainForm and it didn't close Page2. I also went to the FormChangeControls folder and spent some time  looking at the code trying to figure out how to implement it. For instance, the exit button seems to have a ExitButton_Click Sub but no code inside. It tried using it in that application and it didn't close the forms or application. If I close the MainForm with the "X" I get a StackOverflow.

Next I created a new test application using MainMenu as my startup, MainForm as my startup form, a FormChangeButton to page2, a FormChangeButton back to MainForm. Navigation seemed to work ok, but the forms don't start in the same place. I saw some commented code with MenuPos and assume that helps put forms in the same spot, I will experiment with that later.

But the exit button doesn't close the application or forms. I have seen some help files referencing Me.Close() but when I put that in the ExitButton_Click sub I still get a stackoverflow.

To use Advanced HMI it seems that a deeper knowledge of VB.net and Visual Studio is needed, but short of an intensive bootcamp or school I don't know where to start. The Microsoft and YouTube videos and files I have found all seem to skip the fundamentals also. I have done some work using OOP in Beckhoff so I somewhat understand properties, methods, inheritance etc. but this gets over my head fast. Any suggestions?

Open Discussion / Documentation, Visual Studio, GitHub and more...

Hi Archie!

I don't know if you remember me, but I visited you several years ago asking about animating objects in Advanced HMI for a ControlLogix HMI. At that time I had not done much with Advanced HMI, or for that matter Visual Studio.

After doing some research on VS I found many suggestions for code development, including that of committing code to Git so that things can be tracked and reversed. I have also looked through this forum as part of my learning experience.

As many have mentioned here, most questions are solved by looking for help on VS and Visual Basic/.NET, but it opens a huge can of worms for those of us who are very experienced in PLC topics but not app coding and all the associated languages.

As part of my learning journey I have taken many of the help files and comments in your software and put it in a Word document with chapters, headings etc., which I would be happy to share with anyone who wants it. Unfortunately I don't see an easy way to collaborate on such a document, so right now as I find different questions that need to be answered I just write them up and add them to my document.

I am still struggling a lot with some basic things that would be simple if using FactoryTalk View, WinCC or even VISUs in CodeSYS or TwinCAT. Things like screen switching, creating an interface for setting up communications (IP address, slot number, subroutine concatenation with tag addresses, etc.) I am sure this has been done by many people, but despite this being an open platform I have found very few code examples that help answer my questions. Without my work in TwinCAT and CodeSYS I would be completely lost in Visual Studio.

Several regulars on this site have rightly chastised new members for not researching Visual Studio coding more before asking questions, but I fear it is a multi-year exercise to learn the ins and outs of this type of coding, even with my extensive experience in programming PLCs, including ST.

Any pointers you might have in finding more examples of deployed HMI code or better VS training?

Open Discussion / Microsoft Visual Studio with TwinCAT 3 interfering with Advanced HMI execution

« on: March 26, 2024, 02:12:44 PM »

Hi All,

I originally installed my Visual Studio to run TwinCAT 3 from Beckhoff. As such, there are a lot of TwinCAT specific tabs on my toolbar. I didn't think this would interfere with developing with Advanced HMI, but it seems to. The software installed, I can create screens, but when pressing Start to test the application it says you can't start it directly as it is a Class library. I have attempted to create a separate console application and reference the Advanced HMI project as advised, but it creates hundreds of errors. Many of the errors point to the Root namespace of MfgControl.AdvancedHMI, which is apparently the default. Are there any simple fixes for this, or can it be run on my Beckhoff-ized Visual Studio at all?
