Determining Total Number of Operations

[ad1187]

Hi all. I'm trying to create a true/false variable for use within my post where 1=all operations have been posted or 0=not all operations have been posted. I'm comfortable writing the logic, but the problem I'm having is determining the total number of operations in a toolpath group regardless of which operations are posted. Being that only operations selected for posting are output to the NCI file, is there any way to "look ahead" to see if any operations exist after the last posted operation? Any help is appreciated!

I'm pretty sure you'll need to call a NET-hook from your post in order to do this.

Posting in Mastercam only generates the NCI and related data for the selected operations.

If they all have the same program the software already asks if you want to post all ops.  Is that not effective?

Just shooting from the hip here but you might be able to create two variables, increment one by +1 on every op then set the other =  opinfo(15240,0) of the last op and if they are not equal throw an error. Theoretically, total number of ops should equal the op number of the last op unless my math fails me.  Evaluate it in peof so that if var1 ne var2 = error message.  That's where I'd start if you want it specifically in the post.

I think that check only works if the first op and last op in the machine group are posted.

Let's say we have 5 op's in a machine group; that check would work if ops 1, 3 and 5 were posted, but wouldn't if ops 1, 2 and 3 were posted.

Yep, totally see what you're saying.

The easy fix without writing a C-hook or  Net-hook, is to use Select All Operations > Right-click > Change NC Filename.

That way all the Ops have the same name, and you can select 'all ops' and Post.

But but but, that would mean paying attention and doing your job.....blasphemy!

If you are interested in a NET-Hook solution the below code may help.
 

        public override MCamReturn Run(int param)
        {
            var postArgs = PostingManager.PostProcessorArguments;
            var postArguments = (PostProcessorArgumentsType)postArgs;

            var opID = postArguments.Argument1;
            if(!int.TryParse(opID, out var operationID))
            {
                return MCamReturn.ErrorOccurred;
            }

            var returnArgs = PostingManager.PostProcessorArguments;
            var returnArguments = (PostProcessorArgumentsType)returnArgs;

            if (AllOpsPosted(operationID))
            {
                returnArguments.Argument1 = "1 ";
            }
            else
            {
                returnArguments.Argument1 = "0 ";
            }
          
            PostingManager.PostProcessorArguments = returnArguments;

            return MCamReturn.NoErrors;
        }

        private bool AllOpsPosted(int operationID)
        {
            var currentOperation = SearchManager.GetOperation(operationID);
            var allOperations = SearchManager.GetOperations(currentOperation.GroupNumber);

            foreach (var operation in allOperations)
            {
                if (!operation.Selected)
                {
                    return false;
                }
            }
            return true;
        }

 

Below is a sample post that shows how you would call the NET-Hook.

fs2 4 1 0 1 0

pheader$
      "(--- Start of File ---)", e$
      *e$

psof$
      "(--- Start of File ---)", e$
      *e$
      pAllOpsPosted(op_id$)
      if (allOpsPosted),
      [
        "All operations posted", e$
      ]
      else,
      [
        "Subset of operations posted", e$
      ]
      *e$

peof$
      "(--- End of File ---)", e$

fmt "" 4 opID

dllReturn    : 0
allOpsPosted : no$

sdq              : '"'
sspace           : " "
snoArgument      : "noArg"

sDLLArgs         : ""
sallOpsPostedDLL : "AllOpsPosted.dll"

pAllOpsPosted(opID)
      sDLLArgs = sdq + drs_str(2, opID) + sdq + sspace + sdq + snoArgument + sdq + sspace + sdq + snoArgument + sdq
      dllReturn = dll(sallOpsPostedDLL, sDLLArgs)
      allOpsPosted = rparsngl(spost_arg_0$, 1)

Thanks for the replies everyone. This forum is a fantastic resource. Sounds like it's time for me to jump headfirst into the world of NET-hooks.
