Select simple cases when printing tables

[Jelle.Visser]

I'm trying to select only the simple cases before I print my reaction forces to csv.

However, reading through the documentation, I do find options to create cases, but I do not find a way to select a case for a table. I loop through the tables, and certain ones are "printed" to csv. However, now Reactions are all cases, I only want simple cases.

I tried to implement a solution given by @Stephane.kapetanovic

However, this does not seem to work. I would prefer to just the loadcase just for one table, because for the stresses and ratios I do want the combinations to be included.

                    Dim ViewMngr As IRobotViewMngr
                    Dim ActiveView As RobotView
                    Dim CaseSel As RobotSelection
                    Dim ActiveViewNumber As Long
                    ViewMngr = RobApp.Project.ViewMngr
                    For k = 1 To ViewMngr.ViewCount
                        If ViewMngr.GetView(k).Window.IsActive = -1 Then ActiveViewNumber = k : Exit For
                    Next k
                    ActiveView = ViewMngr.GetView(ActiveViewNumber)
                    CaseSel = ActiveView.Selection.Get(IRobotObjectType.I_OT_CASE)
                    CaseSel.FromText("Simple Cases")
                    ViewMngr.Refresh()
                    Console.WriteLine("Selected Simple Cases" & vbCrLf)

Now it crashes on line 10 (line 198 in the full script) with the message:

System.NullReferenceException
HResult=0x80004003
Message=Object reference not set to an instance of an object.

hi @Jelle.Visser 

the context is not the same

you confuse the selection of preliminary load cases to a parametric view with that relating to tabulated results

[Jelle.Visser]

Ah yes, I assumed I was doing something wrong. 
Can you point me in the right direction for selecting the active cases for tabulated results?
The documentation doesn't seem to have a clear solution, or at least I'm not seeing it.

@Jelle.Visser 

ok,

can you give me the full code?

The extract communicated concerns only the blocking point but it is not what you want.

I can't paste the entire code here, that would be a bit long, but here is the repo:
https://github.com/Tebulo-Engineering/RobotAPI

The place where I tried to set the load case is line 189-201, and I print the reactions to csv on line 284 and onward

hi @Jelle.Visser 

each RobotTable has a function Select that can accept for first IRobotSelectionType and for second parameter a string that could contain load cases
Ex : MyTable.Select I_ST_CASE, "1 2 3 ... "

Best regards

[Jelle.Visser]

Now when I add the following line after the if statement to check if it's the reactions table, it doesn't output any reaction csv anymore at all.

tf.Select(IRobotSelectionType.I_ST_CASE, "1 2 3 4 5 6 7 8")

Do note that I am programming in VB.NET, seeing your code, I assume that's vbs/vba?

The first 8 cases are the simple cases, so that's what I'd want to select, but as long as it works, it shouldn't be hard to change it.

hi @Jelle.Visser 

tf refer to RobotTableFrame  

Select method is part of IRobotTable interface

t is RobotTable and come from tf RobotTableFrame by method Get

Imports RobotOM.IRobotSelectionType '< at beginning
[...]
Dim t As RobotTable
Dim tf As RobotTableFrame
t = tf.Get(j)
t.Select(I_ST_CASE, "1to8") ' equivalent to IRobotSelectionType.I_ST_CASE

note that you can select bars by same method

t.Select(I_ST_BAR, "1 2 3 ...")

Thank you, that works!
