DC_GetColArray() - suggestion

Hi, Roger.
I do use DC_GetColArray() intensively in the DATA codeblocks of all my array browers. But if those arrays are empty, maybe in a statistics module, all DC_GetColArray()-calls return empty
strings. So now, I have to catch the length of the array source inside all codeblocks (DATA {||IF(Len(oBrowse:dataSource)>0,"--",DtoC(DC_GetColArray(1,oBrowse)))}), which is not very elegant. What about a forth parameter setting a DEFAULT value?
Code: Select all
FUNCTION DC_GetColArray( nElement, oBrowse, xVar, xDefault ) // here
LOCAL aArray, nPointer, xValue
DEFAULT xDefault := '' // here
aArray := oBrowse:dataSource
nPointer := oBrowse:arrayElement
IF nPointer > Len(aArray) .OR. nPointer = 0
RETURN xDefault // and here
ENDIF
IF nElement == NIL
RETURN aArray[nPointer]
ELSEIF nElement <= 0
RETURN nPointer
ENDIF
xValue := aArray[nPointer,nElement]
IF Valtype(xVar) == Valtype(xValue) // should work anyway
aArray[nPointer,nElement] := xVar
ENDIF
RETURN aArray[nPointer,nElement]
My codeblocks could changed to this with a default for DC_GetColArray():
Code: Select all
DATA {||DtoC(DC_GetColArray(1,oBrowse,,EmptyDate()))}

Tom -
That sounds like a good idea.
Did you test that code?
If so, I will copy it into my source for the next release.
Roger
BTW - Just upgraded my firmware in my Phantom 3 to support Way Points.
Going out today to test it. Today is a holiday here in the U.S. - Labor Day.

Hi, Roger.
No, I didn't test this. I will do in the next days.
I'm going to install the P3 update on the weekend. Not only waypoints, but a relative flight mode and, wow!, "follow me". I'm going to find a cool location where I'm going to ride a bike and let the phantom fly behind. By the way, did you recognize that the camera will be able to shoot 2.7-K-videos with the update? That's quite cool!

I know. This is cool stuff if it works.

I saw that. I guess we are professionals now.

We
are anyway.
But. Mmh. If you say "She's a professional" in german, that has a very special meaning.

I hadn't thought of that. Ha.
I'm heading out now to my daughter's house. There's a lot of space out there to test out the new features.
Gonna strap the Phantom to my trike.

I am a big fan of the "Point of Interest"
Nice to see the feature set available to the Phantom 2 being brought forth to the 3.
Also, our Police Department just received our Aircraft Registration number from the FAA and will soon receive our official COA (required for government entity).
Been logging a lot of flight hours between my Phantom 3 and the Walkera Runner 250 (which you actually have to fly compared to the DJI).

Hi Rick -
Well I loaded the software, but haven't had a chance to figure out the waypoint system yet.
No documentation.
I'm leaving on a 3-week trip tomorrow.
Going to see family, then on to Terry Wolfe's place followed by a weekend with Jim Graham on the lake.
Then on to my Navy reunion. I will capture lots of videos of my trip.

Enjoy your trip, if passing through the Windy City, I would love to have dinner again.
