Howdy,

OK, there is one small problem with this method, and I think I'm just going to scrap the idea of having the units displaying. The problem is by resetting it to a string, it screws up the formula ability. I can't type in a "+" and a number to add to the current value, anymore. :o(

Oh well, displaying the units was just for looks, but functionality is more important. ;o)

Adios,

Have you tried the Parser class? This means evaluating the strings yourself (basically) but it does evaluation just like Cinema 4D does automatically.

Here's an example if you haven't used it previously. Note the method where the parser is used. If you need this for AM, it may require a different method be invoked (Message() or SetDParameter()).

Howdy,

Wow, I didn't even know that class existed. :oO

Have you used it before?

Edit:
DOH! I see you have.

Howdy,

Well, I cheered a bit too soon. It works but not on an intel Mac, in either R9 or R10.

I'm testing R9.1 on a PPC Mac and an AMD PC, and testing R9.6 and R10.1 on an intel Mac, and R10.1 on the AMD PC. It works everywhere except the intel Mac. What's the deal with that? :o(

No problems here on an Intel Mac in R10.111 - though I'm not using any units.

What version SDK are using for these? Does it completely fail or is it only failing with particular formula operators?

Howdy,

It totally fails on the intel Mac.

Actually, the only place it works properly is on the G4 PPC Mac and on the PC in R9. R10 on the PC is giving me the wrong result.

If I have a value of 0.254 already in the dialog's edit number field, and I type in at the end of that "+1", and hit tab or enter, the result should be 1.254.

But these are the test results:
G4 Mac running R9.1 - result = 1.254
G4 Mac running R9.5 - result = 1.254
G4 Mac running R9.6 - result = 1.254
G4 Mac running R10.5 demo - result = 1.077
PC running R9.1 - result = 1.254
PC running R10.1 - result = 1.077
Intel Mac running R9.6 - result = 125.4
Intel Mac running R10.1 - result = 78.419

OK, first in the GeDialog::Command() function I have this:

> case MY_EDITNUMBER: \> GetString(MY_EDITNUMBER,str); \> val = ParseString(str); \> SetReal(MY_EDITNUMBER,val); \> SetString(MY_EDITNUMBER,RealToString(val)+uStr);

My parser function receives the string and first strips all of the letter characters from the string (A-Z and a-z) and then parses the remaining string. It seemed like the letter characters were interfering with the parser's result.

Then I have a print statement after the parser evaluates the string in my ParseString() function to print out the result:

> GePrint("String = "+expression+" = "+RealToString(rVal));

On the G4 Mac and PC in R9.1 it prints:
String = 0.254+1 = 1.254
Which is correct.

On the G4 Mac and the PC in R10 it prints:
String = 1.077 = 1.077
it looks like Cinema parsed the string before it got to my parsing function, I'm assuming it parsed it before the GeDialog::Command() function. :o(

On the intel Mac in R9.6 it prints:
String = 0.254+1 = 1.254
Which is correct, BUT the output to the dialog is 125.4 :o(

On the intel Mac in R10 it prints:
String = 78.419 = 78.419
Again, it looks like Cinema parsed the string before it got to my parsing function. :o(

The Parser class in both R9 and R10 SDK's are identical. So, needless to say, I just may go back to the "no unit display" in the number edit field. :o(

Trying to get the unit string into the number edit field is becoming too much of a hack, and I'd much prefer proper functionality for the plugin.

Thanks anyway.

Adios,
Cactus Dan

Howdy,

OK, sorry about the intel Mac running R9.6. It's actually correct, but I had another field set to a value that was mulitpying it by 100, so that was a simple DOH! mistake on my part.

But I'm still curious why in R10, it parses the string before my code can get to it. :o(

It may be that Message() is getting to it first.

I noticed that I use both in my code - in my non-modal plugin dialog Command() is used whereas in the modal dialog Message() is used. I don't think that this is by accident - but can't remember why it was done these different ways.

Howdy,

Hmmmm, could be.

But I'm done going back and forth over this minor problem. The rest of my plugin is ready for release, and I'm letting this silly little thing hold me up. :o(

I can always add that in an update. I've only commented out the functions for it so that when I get back to it, I won't have to start from scratch. ;o)
