Displaying text or objects from one module to the other using links

So, by sceario is I have two modules, one the source and the other the destination.  What I would like to do is link from the source to the destination, and have the text or image from the source appear in the destination module, via the link.  I can get it to work for text, but I am not able to get it to work for images.

I just want to maintain text or images in the source module, while dynamically updating the destination module using the link, is that possible?

Hi,

It depends a bit on the image.  Use richTextWithOle works for me in most cases.

Not sure what you mean by maintaining text or images in source while updating the destination module.  You would need to make the changes to the text and image in the source module, not the destination.

Maybe it would help if you added what your current dxl is?

You create the links manually.

The standard way for most folks to display info of linked objects is:

• Use the Analysis Wizard to create a Layout displaying some information of the linked object.  Re-run the wizard until you are happy it is finding the correct linked objects to display.
• If you don't see exactly the info you want, then edit the Layout DXL code near the "s=" and "display" commands.
• When the layout is satisfactory, use the tool to convert it into an Attr-DXL.  Save the module.
• Delete the layouts, add the attr-DXL to the view, save the view

In your specific case I'm guessing the Layout is retrieving and displaying raw text.  You will need to edit the layout..

• Find <othero."Object Text"> and change to <richTextWithOle(othero."Object Text")>
• change <display s> to <displayRich s>.

When you give up on that, post the layout code and someone will tweak it for you.

While layouts are reasonable for simple displays; displaying linked objects (and other rather intense code) is a disaster in Layouts since it gets run extremely frequently; 10 times a second while you move the module window around.  Attr-DXL runs a single time (after opening module and displaying object).

Try changing s = probeRichAttr_(othero,"Object Text", false)

to s = richTextWithOle othero."Object Text"

Thanks Greg,

That worked, but the picture is in the DXL for In-Links Column, is there a way to place that image into the actual object text, like I was able to do for the tables?  If not, no big deal, I am greatly appreciated with all the help you have given me.

Thanks in Advance,

Dan

Re: Displaying text or objects from one module to the other using links
GregM_dxler - Wed Nov 13 08:32:35 EST 2013

To put the text and picture in the object text instead of the DXL for In-Links Column, you would change the line

displayRich("\\pard " s)
 

With obj."Object Text" "" = richText "\\pard" s ""

Note that this will overwrite anything that is in there right now.

Hope this helps,

Greg

It did not work, gave me the following errors,

-E- DXL: <Line:52> incorrect arguments for (=)
-E- DXL: <Line:49> incorrect arguments for (if)
-I- DXL: All done. Errors reported: 2. Warnings reported: 0.52

but thanks anyway.

Try getting rid of the 2 double quotes before the equal sign.

Looks like GregM posted while I was typing.  Did his thread resolve your issue?

While you CAN use Layouts/Attr-DXL to modify attributes I think it poor practice.  But if you do don't forget:

• if (!canModify(obj."Object Text")) then don't try to update the Text, module probably open "read"

Yes this tread resolved my issue.

I will keep in mind about your comment Louie.
