VB6 to communicate with Microstation (*.dgn) files

[mortinrido]

Dear All,



I am absolutely just a couple of weeks to learn VB6. Now, I am eager to learn how to communicate this VB6 to Microstation (especially microstation V8).

I just found how to activate the "project--reference" for MicrostationV8 in VB6.
But, I still don't know how to use it.

First, I have several *.dgn files which contain some text files inside those drawing. What I need is how my VB6 control those *.dgn files and change the text automatically as I chose one or more words to replace it with.

For Example :
Test.dgn --> has text inside the file like "TEXT FOR TESTING MICROSTATION".
Then, with my VB6 I would like to open Microstationv8 with "visible = true" so that user might see the "process" going on.
After that, inside VB6, the code will be sent to Microstation to do "action" to change the text into : "TEXT FOR changed Test in My MicroV8".

Please help me...

I cannot paste the code here since I don't know how to use Bentley Microstation Project Reference....

Please anyone help me... That would be a great favor... Please.

Well, thanks for giving me the link. Till now, I am almost "lost" to search for what I need..

First, I need my VB6 to communicate with MicrostationV8... But, I don't know how to do it from the beginning.
Then, with successful communication of that, I might then interact with object in Microstation...
Ugh, I am really eager to know the code. So far, I just could put forward my idea to this forum.

Hi Mortinrido

Just open MicrostationVBA.chm file and search for ApplicationObjectConnector Object, and you will find the way :
When a program running outside of MicroStation calls CreateObject("MicroStationDGN.Application"), the call attaches to a running instance of MicroStation if there is one. Otherwise, it starts a new instance of MicroStation. Subsequent calls to CreateObject("MicroStationDGN.Application") attach to the same instance of MicroStation.

CreateObject("MicroStationDGN.ApplicationObjectCon nector") always starts a new instance of MicroStation. A program can use GetObject(, "MicroStationDGN.ApplicationObjectConnector") to attach to an instance of MicroStation that is already running or to test to see if MicroStation is already active.

See Connecting to MicroStation from a Separate Process for examples of how to use GetObject and CreateObject.
