i am using VB6 using the autocad API.
is it possible to move insert rotate blocks with the autodesk-designautomation api?
Also extract block attributes and change them?
Create new drawings changing DWG block attributes and save them?
if yes. How?
Best Regards
Luis
No, sorry, VB6 is not supported in Forge Design Automation. You'll have to use VB.NET (define an autocad command).

I want – as the title says – extract programmatically a shape from a Draw document through the api interface. Beside I want to import such a shape into a document as well.
I saw some predefined shapes in XML form and the document is stored as XML structure as well. Is there a known way to anybody out there to allow the storage and load of one shape?
What is this good for?
I want to, for example, enable the programmatic deletion of objects. But to enable the undo/redo functionalities I need to “store” the deleted shape. Beyond that this would allow me to add user-defined objects programmatically, e.g. arrow heads, UML structures or unicorns.
Thanks in advance for any ideas,
J
P.S.: I work with LibreOffice Version: 5.2.1.2 . Access the interface through C# (so java and C++ would do it as well) but any ideas are welcome.
I'm not entirely sure what you are trying to do, but here are some ideas:
Instead of deleting an XShape, you could use the dispatcher to Cut it. That will store it in the clipboard, so if it needs to be added back then the dispatcher can Paste it, as long as no other copy or cut was performed.
To create a shape, see the example at https://wiki.openoffice.org/wiki/Documentation/DevGuide/Drawings/Shapes. This code will look different depending on what kind of shape it is. It sounds like you are asking for one code listing that will programmatically create any type of shape, but I do not think it is that easy.
Instead of using the UNO API, you could programmatically modify the XML files, which may make it easier to store and work with any shape. Be sure to use an XML parsing library, not just regular expressions.
I need an open-source solution for visualizing a neo4j graph in a web application. I'm looking at alchemy.js, and it seems pretty cool. What I'd ultimately like to do is use icons for different node types, instead of just different colors. Is there a way to do that with alchemy.js? If so, how? If not, is there a different open-source toolkit that would enable this? Obviously, KeyLines does it, but it's far from open-source.
Thanks!
You can also check out linkurious.js which is open source, based on sigma.js and afaik has customizable images.
I want to make a charting control for an embedded device using Silverlight for Windows Embedded. Currently i am planning to use line shape for drawing the graph.
My question is if its a good approach(performance wise) or should i look for other options.
Or if any controls are available for SWE.
Thanks
Silverlight is not a proper answer to drawing charts on an Windows Embedded Compact device. You should go for using (or creating) a native GDI element. If performance is very important (e.g. for a fast-updating chart), you might also consider DirectDraw.
The best way in a commercial project would probably be to use a readymade component, such as this one.
You can find somebody else's experiences and advice here for pointers to what to look for when doing this yourself. If you expand your post with more details about what you are actually trying to achieve, I might give you a more detailed response.
The answer is stop using Silverlight, since Microsoft is abandoning the product. Do it in Flash—or better yet, use HTML5 and JavaScript.
In recent windows embedded applications that use windows universal apps I would highly recommend oxyplot.

These plots are the best I've found on the internet so far and very easy to use. Best of all they are free. You can get these using a NuGet Package manager which makes getting updates fairly simple.
I'd like to have an interactive floor map (so they're not huge) in my application. The maps will be different for every user, but contain similar elements which only differ by quantity and location. The application will show the map, identify certain elements and link them to information from the database.
To design and store the map, I'd rather not roll my own editor and/or come up with some custom file format. However, it would be nice if the format were open and easily readable. SVG seems to be the perfect candidate for the job. All there needs to be is a convention of how to name the elements to make them identifiable. But how to go from there? I need something that can render the SVG and distinguish between the different layers.
TSVG can do exactly this but depends on FireMonkey which I'd rather avoid - it's not even present in Delphi 2010, so I'd have to use another version and do DLL tricks.
Another option would be to use the Chromium Embedded Framework and create the map using HTML, CSS and JavaScript. That feels very bulky, and would be hard to get right.
Are there any simpler ways to do this that I overlooked, either using SVG or perhaps something completely different?
I'm not sure if a GIS system is appropriate for this. It may very well be overkill.
In the end I decided to go for D3.js using Chromium Embedded, to have a flexible and more portable solution.
What's the best way to draw shapes interactively at run time using Delphi? I need to be able to select, drag and resize the shapes. This will be used to mark up existing images and documents.
This looks like a good starting point, but I'm wondering if there's a more complete library (preferably free) available that will save some time.
Update:
If you're going with a custom solution from scratch, I've seen another example on Delphi Central that might be an even better starting point.
I will recommend you, read some links on my site. Are explained and all the source code is available; You can see and get some usefull for you.
Plugin system in Delphi - Part 2
Not directly what you need, is a plugin system for Delphi. But all the samples are based on a drawing tool that uses Shapes (Creating, selecting, resizing). You can review the code and extract what you need.
Sample manipulating of "Maps and Figures"
Sample of how to create, select and move components at runtime (in this case with TImage).
- Select shapes visually: Shows different ways to select shapes visually.
The web is in Spanish, but you can generate an authomatic translation on the web itself.
Anyway the code is commented.

Excuse-me for my bad english.
One freeware option would be TssControlSizer. Just change the "control" property to the control you want to manipulate resize/move.
Not sure if you've moved on now with this Bruce but if you haven't, it might be worth looking at TMS Components Diagram Studio - it's certainly cheap, and looks quite powerful from the demo.
I would use Flex Graphics (commercial, $499 for one developer, with sources, $1500 for site-license, with source code). When I bought it, it was a lot less than that. So I guess, I wouldn't pay that now. It's a lightweight 'drawing/cad' package.
But as I already own it, I could import a page from the original document as an image, perhaps rendered in PNG or WMF, and then mark it up with lines, etc.
You could think of it as a light "cad" package. It has most primitive shapes, and you can easily create your own new objects or shapes in Delphi classes, that could be "smart shapes" like the ones in Visio.

Another commercial component set that I have heard only good things about is TRichView. They have a TRichViewEdit that looks like you could emulate a document markup environment easily with it.
