Help with OLE Automation

Note that in the code shown in vpt's post, you are accessing the OBjDimCmd object (green lines) before setting it (red line).

You should use ObjCmd, not ObjDimCmd, in the green lines.

+1

Also, you must know what to look for:

* Featurecommands (measured stuff)
* Dimensioncommands (location, position, angle etc)

...then set the command object to either featurecommand or dimensioncommand (depending on the current commands type)
...then access the properties for that commandtype (featurecommand / dimensioncommand)

If I run this like I have it above, then I don't get an error of an unrecognized DimensionCommand, but I still get the zero (I am guessing null) reading for the StrDimDiameter and MeasZ variables. To add in the feature commands, do I write it out like above and do an if ObjCmd.IsFeature then StrDimID = ObjDimCmd.ID, etc?

So, we are one step closer to getting this to work as desired. With this I now have diameters, and all measurements with an AX of M (had that before). So my guess is either I labeled the variables that get the measz variable included or that the measz variable has a feature command of measlength and not measheight.

I so appreciate your patience and all the help. I don't think I could have done this with out it. If I ever make it to Sweden, I will buy you a drink (coffee, soda, beer, whatever your preference). And you never know, since that is on my list of places to travel. My family is from there, many generations ago.

Thanks! No need for a beverage - just post your code here so others can learn and benefit from it.

As a sidenote, I don't think the MeasHeight will give you what you are looking for, though.
If you are looking for the measured Z-value, you should use this instead:



The code can (probably will) error out if it encounter a feature command that does not have a MeasDiam or MeasHeight property,
but you'll probably notice that.

For some reason, this does not like it when I try to reply with the quote.

This is what I have learned:
MeasHeight returns a zero, but the MeasLenght returns a value, even if that is a false value. LOL. So there is some progress. To try to get the correct value in there, I even tried ObjCmd.FeatureCommand.DimMeasured, but that also returned a zero. So no surprises there.

At the same time, I have tried the bit of code that you suggested above, and I always get a return of zero.

So, is there anything else you would suggest? I will keep combing the help section and the book, but I am just taking shots in the dark.

After this you place the MyReading# variables in the locations or the other program that you need the information in.

Why the MeasZ statement works when it is in the functioncommand block and not in the dimension command block or just after the for each objcmd in objcmds statement I don't know. It doesn't make sense to me. But we now have a functional way to export information from PCDMIS and place specific information in specific places.

Again, thank you for all your help.

The MEAS_Z statement works only when it encounters a command with a measured Z-value. Dimensions does not have this.

Also, the best BASIC reference I have used is a file called "automationobjects.chm". Easier to search, look and read than the occasional helpfile/PDF.
I can't seem to find it again though.

Maybe a kind Hexagon-rep could post it here?

OK, now that I know that, it makes sense, but I didn't know before.

Now, that we have a working output method...I have a new task.

We have comment boxes in the PCDMIS program where the operator types in information such as clock number and job number. Would I get that data in a similar fashion to the MEAS_Z method?

Kind of.

The absolutely easiest thing would be to name those comment boxes to a specific name, say CLOCKNR and JOBNR.
You would then enumerate through the commands like you just did, but looking for a command of the comment type.
When a comment command has been found, you check the ObjCmd.ID if it matches CLOCKNR or JOBNR if it does, then you have found your comment/s.
Then fetch the comment input value, can't say off the top of my head (not at work now) how to do it, but it is feasible.
