I want to draw a polygon with 4 points, with my code
I have some trouble, here si my prodedure.

Define like that:

VAR CONSTANT
      iCount : INT:=4; 
END_VAR
VAR
   pPoints : POINTER TO ARRAY[1..iCount] OF VisuElems.VisuStructPoint; 
END_VAR

Code:

//Fill some data to pointer
pPoints:=ADR(aIndex5004); 

Then I draw a polygon with 4 random points, enter in fields:
Array of points: PLC_PRG.Graf_dizaFB.pPoints^
Number of points: PLC_PRG.Graf_dizaFB.iCount

PLC>Login and nothing realy happens...? pPoints array y and x is filled with random numbers eg.from 40 to 100. The polygon dissapears, sometimes I get error: paint buffer memory too low.

What do I do wrong?

regards,
Alex

VAR
   aVisuStructPoints : ARRAY[0..4] OF visuElems.VisuStructPoint;
   pVisuStructPoints : POINTER TO visuElems.VisuStructPoint;
END_VAR

aVisuStructPoints[0].iX := 10;
aVisuStructPoints[0].iY := 20;
aVisuStructPoints[1].iX := 20;
aVisuStructPoints[1].iY := 20;
aVisuStructPoints[2].iX := 10;
aVisuStructPoints[2].iY := 40;
aVisuStructPoints[3].iX := 60;
aVisuStructPoints[3].iY := 20;
aVisuStructPoints[4].iX := 80;
aVisuStructPoints[4].iY := 20;
pVisuStructPoints := ADR(aVisuStructPoints);

Then in the visualization refer to <instance of="" fb="" name="" prg="" or="">.pVisuStructPoints
In the number select 5 (for this example)</instance>

TimvH it does not work??

I used V3.5.5.1 with the Control Win. This works fine:

I copy-paste it from you TimvH...

Well i do not get it, it simply just don't work with me I also created FRESH project with control WinV3 (I'm using 3.5.4.2). Online>Run (not SIMULATE!). I get this: (attached picture)

Ok,s something wrong with me or with Codesys? I'm loosing my head because of this!

Any other suggestions, I'm going to instal 3.5.5.1. If won't work, I will... better not to say.

Well, YES! It works with 3.5.5.1. Question is, if it will work with my target??? I have win RTE 3.5.2.1, on xp embb.
I'm going to make some test during day...

Thank you TimvH for your efforts, I appreciate!

Alex

YES it works with IDE 3.5.5.1 on RTE 3.5.2.1 platform. I created fresh new project in 3.5.5.1 and copied my existing project from 3.5.4.2 into. works like a charm, and many other troubles are gone.

I specialy like new function Refactornig, it's just great.

Thanks again TimvH,

regards,
Aleksander
