Hello, I?\_Tm considering using ScreenMaker to rewrite some of our custom Flex Pendant screens for spray robot applications. I?\_Tve figured out how to call .NET functions to interface with my own code, but I wonder is it possible to read/write the state of controls from the ScreenMaker toolbox directly in .NET? One of my current screens has 16 CheckBox?_Ts on it?_" I use them to read/write a binary coded number between 0-65535 to a PERS num datatype. I already have C# code to handle this, but can?\_Tt find an easy way to do this in Screen Maker. It looks like I would have to link each of the 16 boxes to an application variable and then read/write those variables to a .NET function (that’s a LOT of work in ScreenMaker). Any suggestions on an easier way to convert a group of (binary) CheckBoxes into a num data would be greatly appreciated. Also, I was able to this same thing many years ago with the S4C+ version of ScreenMaker. Thanks in advance, Toby ---

Hi Have you tried to create a virtual IO board and define 16 digital outputs (0-15) and one group output (mapping 0-15). This way you can bind each of your CheckBoxes to one digital output in ScreenMaker and use your group output to read the numeric value in the Rapid code. It’s a workaround but seems to work… -Osku ---

Osku, Yes I thought about doing it that way, but like you mentioned, it?\_Ts a workaround. I actually have 64 total check boxes in the screens that need to be coded from binary, it doesn?\_Tt seem like a clean way to handle it. I would much rather keep all of the code in the application, but I don’t yet know enough about how the .NET code ties into ScreenMaker. ---

Hello, You are interested in re-creating a screen from FPSDK in ScreenMaker. Take look at this posting, it gives some details: [http://forums.robotstudio.com/forum\_posts.asp?TID=3683](http://forums.robotstudio.com/forum_posts.asp?TID=3683) This could be an option, provided your screen is not too complex and is referring to lot more external components(dll). Just give it a try. Hope this helps. Regarding how the .NET code ties with ScreenMaker, refer to this post: [http://forums.robotstudio.com/forum\_posts.asp?TID=2903](http://forums.robotstudio.com/forum_posts.asp?TID=2903) Thanks ---

Thank you. I was able to add one of my own FPSDK screens into ScreenMaker, I?\_Tll work more with that to see if I can get the rest of my application to work that way. I’m going to post another topic about how to create ?_oThird-Party Controls?_\_ in Screen Maker. Hopefully you can share some links on that. Thanks again, Toby
