This is in continuation to Getting ArcMap reference without launching application?.
The idea of the application is to map layers (pointing currently to an unreachable server; server may be down, non-operational or behind a firewall) of a MXD/MXT of a document to another data source.
While I was able to achieve it, I faced a different issue as I move forward.
These are the steps I followed:
- Checkout ArcEditor license
- If checkout successful above, try connecting to SDE.DEFAULT
- If connection to ArcSDE successful, parse map layers
- For every layer parsed, change its source
- Finally, save map and close
The issue is, as soon as I try to get the map count (data frames) in the document, the application throws a HRESULT error (see below), and I am unable to proceed.
could not be found. (Exception from HRESULT: 0x80030002 (STG_E_FILENOTFOUND))
I searched the internet for this error and at some places they have talked about ArcGIS not being able to "access" a file. In this case I doubt if thats an issue...
I am attaching relevant portions of the code, showing the location of the error.
I am not sure where I am going wrong.
