Create image for ImageControl

[Dieter @ DWorks]

I now how to make an ImageControl using: CreateImageControl.

The last parameter is a handle to an image.

The question is: how to you create the image?

I tried to create things in the pio and return the handle to the image control, but it doesn't work.

[Robert Anderson]

The handle is to a symbol def. Draw things into a (usually temporary) symbol definition and get a handle to it...

[Dieter @ DWorks]

k, thx, I will try this

[Dieter @ DWorks]

It's not working Robert,

I created the symbol, got the handle to it, but nothing happens.

Is there something else that needs te be done? Or is this not working in 12.5?

Hi D

Robert seems to say you want the handle to the symbol definition in the symbol folder, not the symbol instance in the drawing.

Not sure from your post which one you're using.

[Dieter @ DWorks]

I got the handle from ActSymDef.

And this after using SetActSymbol.

And this after using BeginSym-EndSym.

This is the symbol definition right?

[Robert Anderson]

Create a symbol you want to use for the graphic.

Use GetObject() with ths symbol name to get a handle to the symdef.

BeginSym and EndSym are when you are creating a symbol def in the script. Which you might want to do if you're changing the symbol around, but it isn't necessary to use the symbol display control.

Or if you have an instance selected in the drawing use:

GetObject(GetSymName(FSActLayer));

[Dieter @ DWorks]

Nope, GetObject() doesn't work either.

I see the symbol in my resource browser, so it's created with the script.

Maybe there are requirements I need to consider on how the symbol must be? Size? No?

Edit:

should I use SetImageControlPath? Because that function is not working! And I think it's because of the lengt of its function name. There is also a SetImageControlHandle. And I noticed that when you have two names where the first 'x' letters are the same, VS think they are the same!

Can you post an example that's working with that imageControl? I tried so many different things and it is not working.

Note that I used CreateImageControl and not CreateControl because I do not want to use an extra (vss) file

Anyone?

[Charles Chandler]

Use CreateSymbolDisplayControl instead. There's an example in the online function reference.

By the way, VectorScript recognizes the first 20 characters of function, procedure, constant, and variable names. Characters after that can be present but are ignored.

[Dieter @ DWorks]

that's a good alternative to use. I check this out.

Although I have a workoaround now, I would like to see this problem solved.

Hello.

This works...until there's a symbol.

What about a permanent image control in a dialog ? A handle to a picture ?

Thanks in advance.

[arthur&l?on]

Auto-answer.

OK. The trick is to create symbols by script and erasing them after having called the dialog. Simple.

1. PIO (door for example)

2. Check-box in the info palette calling the dialog (a vss in this case)

3. Go back to the PIO after having hit 'OK' and uncheck the check-box. The symbols created are erased by the way.

I found these problems :

- The screen doesn't regenerate even with 'redrawall'. There's to put a 'SetZoom(GetZoom)' in the pio code.

- The latest symbol drawn remains in the ressource palette.

Your screen redraw problem is because you are showing the dialog during the object reset event. You need to use an event enabled object with a button to run the dialog.

You can create a temp symbol by using BeginContext and EndContext(0) within the script.

[arthur&l?on]

Thanks for your reply.

The button deal seems more hermetic to me, anyway.

There's some info around ?
