hello world - external

[dachshund694800]

hello

i tested some basic stuff like the "hello world" programm and this is working fine. but can anybody explain me: is it possible to run commands from an external application? i googled a lot, but i found nothing.
for example: "hello world" for revit in a windows form application. by clicking a button on a win. form "hello world" should appear in revit. the windows form or *.exe..... should be executed external from revit, not a generated window in revit.
is something like this example possible? and if so, where can i finde some information...

thanks a lot,
t.

i think i expressed myself badly. i only want to know:

how is it possible to start an add-in external from revit?
thanks a lot

You want to drive Revit from another process (out-of-process). You can not. Revit only supports in-process.

You need to write an in-process addin, then use an IPC (Inter-Process Communication) technology to "speak" to your addin from an external process. There is a post here showing how to do that with AutoCAD. May be the same trick can be used on Revit.

thank you this is what i need for revit. i dont want to drive the whole revit from another process. i want to start an revit add-in from another process.
