I'll conclude with this little snippet.
Although I got it to work in the little sample code (Olaf's ChartJSON demo), I had fits trying to get it to work in my project. It was getting too...

Actually, I did not see this post as it snuck in right before my post on my unrefreshed browser.
Just noticed it now.
But as you see in my latest post, I did figure it out. The...

Just for outside access testing purposes, I put the ShowTrendline() call just before Chart.RenderTo() in DrawChartToPicBox since the CC is created here anyway. In my project I'll fetch the CC so I...

I was just about to post this following my last post:
Noting that the object pointer is not the same.
I don't believe that DrawChartToPicBox() is what's causing my outside call issue.
Note...
-
That was what I tried to do initially.
Declared a temporary object variable and Set it from one of the indexed collection objects.
Then I'd try to manipulate the properties from the temporary...

NEW QUESTION but associated with the @jpbro modified code in this thread.
The manipulation of the class properties are being done from within the cChart class.

Cool. Thanks. I'll add this to my list of educational "to-dos". :wave:
-
I don't know how safe the download was, but I have it now. I'll check it out. Thanks.
-
Yer a very clever guy @jpbro.
No wonder you understand the RC6 so easily.
Thanks for tossing that code in. I've not seen that kind of action before. :D

I'm puzzled about what happens at the conclusion of this With...EndWith
With ModifyTrendTool(1)
' Modify as many properties as you like in a With block call to ModifyTrendTool

I actually have that app, although never used it.
Just thought there was a 'viewer' that was part of VB6 that he was referring to.
Thanks.

As I go through information graciously provided by @jpbro, I come across a mention about
"...by examining it's export table using the dependency viewer"
Where is this Dependency Viewer where I...

Oh this is very interesting. Talking about "strange new worlds and civilizations, to boldly go ..."
I'll be spending some time on this I can tell.
THANKS for providing this @jpbro

Seriously? 60 views and not one person is knowledgeable about collections and objects???

Attached is Olaf's JSON demo code where I added what I'm trying to ask.

There is a collection of cTrendTool objects.
To draw these the cChart object's RenderTo() is called that...
-
Thanks for the code example. Very informative.
-
Thanks to all who contributed above.
Lots of good examples for future reference on VBForums. :)
-
Appreciated it. Superior to the one I did that took me forever to get to that point.
-
While moving it you are making it longer, shorter, changing angles, etc.
It's a stretchy line and you drag the ends.
Drag the center, yeah it's one length then.
-
Line Length is a constant?
I'm drawing a blank.
-
Thanks for posting this code.
Unfortunately it doesn't seem to work as is.
I've placed a couple of Debug.Print lines so the data can be viewed:
X1: 672 Y1: 583.8126 X2: 907 Y2: 421.5382...

Searching as in "Site:vbforums.com detect click on line"
Looking for code that will do this.
Thanks for the spelunk.
As it isn't VB6 code, I can only assume the following and unfortunately...
-
I've tried so many approaches to this. This is the closest I've gotten but it loses accuracy if you click near either end of the line (going in the same direction/angle). And any line near vertical...

Just another RC6 question collecting webs.... nm
-
And I figured it out. NM. :wave:
For future reference (there has to be a conclusion, right?)
Add a DrawCPs method to the usercontrol.
Call the DrawCPs method from the tool object.

I really must be stressed out.
Of course.
Too many fires.
Thanks jpbro. Understood and duh-hee-advised! (how could I not see this????)
And I'll bet the reason I still have not figured out...
-
Thank you sir.
When you said "multiple and wondrous ways" it brought back memories of when Disneyland was that. So long ago....
But seriously, I do understand this.
CORRECT ME IF I'M...
-
The reason I had it in the uc resize is because I've been learning from Olaf's Cairo demos and that's where he had it.
Example from CairoTutorial (6 Spline-Interaction)

-
I didn't mean 'several methods' as in multiple actual class methods.
I meant 'several methods' as in "several ways/approaches to skin a cat." ;)
-
This code is just a quick test code and I'm taking shortcuts to make it.
Olaf keeps telling me to include it with the question, so I spent all day putting it together.
My project itself is too big...

Okay, persistence paying off. Seems usercontrol Resize going through a double call.
1. When the program starts the usercontrol goes into play before the form. This triggers the first usercontrol...
-
The 'object already open' appears to be caused by referencing the main form (fChartHost) from the usercontrol. By commenting out some lines, I got it to tell me that the form is open in designer...
-
Done. Was an oversight. Forgot it was in there.
Thx.
-
I'm sorry about that. Forgot it was in the same folder.
I originally created the .exe simply to catch compile errors and forgot to delete.
Again, my apologies.

Removed .exe and...

Clearly explained issue. check.
Provided short code. check.
While this thread waits for some response, I'd like to use this empty time to post some thoughts.
I asked A.I. a question about...

Hey @jpbro
Been pretty busy, eh? Thanks for responding.
Their effectively the same.
Having several methods doing the same thing is where choice confuses the learning.
:)

While retracing my steps trying to find what is causing my errors, I noticed another confusing thing about the RC6 context and surface assignments.
Public Srf as cCairoSurface
Public CC as...
-
Well, I spent the day writing an 'example' app to try and simulate some issues I've run into. Wish it could be an exact representation, but I think this is close enough.
The controlpoints are not...
-
Well, I've spent hours today trying to create 'working code' that could be used for posting here to duplicate an issue.
I've tried starting from your ChartJSON code, but that got pretty convoluted...
