Rack Dimensions from DLL

I am trying to create instances of a rack from a DLL. It works to the point where the data is correctly set and I can verify this in the object tree. However, the visual display of the rack still shows the default rack you would find in the library (10 bays with 10 levels each). The visual image of the rack is correctly displayed when I open the properties of the rack and click on any column in the list of bays in the SizeTable screen.

Is there a way to repaint the object by making a specific function call in the code after I am done adding all the bays and levels?

The following are relevant snippets of code I am using:

Creating the rack and setting the sizetable to 1 bay with 1 level:

//for each rowID, create a new rack
treenode rack = createinstance(node("MAIN:/project/userlibrary/CustomLib/CustomRack"),model());
//setlabelnum(rack,"setSize",1);
treenode sizetable = getvarnode(rack, "sizetable");
clearcontents(sizetable);
nodeinsertinto(sizetable);
treenode tempbay = last(sizetable);
setname(tempbay,concat("Bay",numtostring(1,0,0)));
nodeadddata(tempbay,DATATYPE_NUMBER);
setnodenum(tempbay,3);
nodeinsertinto(tempbay);
treenode templevel = last(tempbay);
setname(templevel,concat("Level",numtostring(1,0,0)));
nodeadddata(templevel,DATATYPE_NUMBER);
setnodenum(templevel,3);
setname(rack, concat("R", numtostring(itRowGroupList->getId())));

adding a new bay or modifying exiting one (this is called inside a loop):

//get existing bay or create new
treenode bay = first(sizetable);
if(bayCount > 0)
{
	bay = createcopy(last(sizetable), sizetable);
}
clearcontents(bay);
nodeinsertinto(bay);
templevel = last(bay);
setname(templevel,concat("Level",numtostring(1,0,0)));
nodeadddata(templevel,DATATYPE_NUMBER);
setnodenum(templevel,3);
setname(bay, concat("Bay", numtostring(itRowBays->getId())));
bayCount++;

adding a new level or modifying existing one (this is called inside a loop):

//get existing level or create new
treenode level = first(bay);
if(levelCount > 0)
{
	level = createcopy(last(bay), bay);
}
setname(level, concat("Level", numtostring(itBayLevels->getId())));
levelCount++;

Once the above loops are complete, I would like to repaint the object. repaintall() or repaintview(rack) does not seem to work.

Thanks in advance.

function_s(node("/Rack", library()), "RefreshTable", rack);
repaintall();

Thanks for the reply Phil. I tried that but I am unable to call function_s from the DLL since the function definition in the DLL is as follows:

inline double function_s(treenode node, char * name, n30argsdefaultinterface){return function_s_alias(node, name, n30args);}

This translates into function_s(treenode node, char* name, double n1, double n2 ...). This will throw an error at compile time.Is there a workaround? or another function?

What error at compile time are you getting?

If it is that you can't convert a treenode to a double, then use the tonum() command:

function_s(node("/Rack", library()), "RefreshTable", tonum(rack));

It is the treenode to double error. However, if I try use tonum, it says function undefined. Maybe this function is not declared in DLLMaker?

Try adding DECLARE_FLEXSIM_FUNCTION(tonum) to your FlexsimFuncs.h

Easy way out is simply calling function_s on a flexscript toggled node in Flexsim and then call that node from the DLL with nodefunction()

This worked.

Its typedef was already available in FlexsimFuncs.h,

typedef double (*_tonum)(treenode x);

However, the declaration was not there for some reason. Adding it fixed the issue. Thanks!

I am able to call the function_s as suggested by Phil and it paints the rack correctly in the 3D View.

I tried this and it worked as well. Thank you.

I added the following node under labels node of the CustomRack object in my userlibrary as shown in the attachment below.

and called the following code in the DLL:

nodefunction(label(rack,"repaintObj"));
