Project experience: in view of the error reported by FDO to connect to the SDF file yesterday, the National GIS Forum provided an idea to help me pass the customs .. fdosdf

For C #, the following error occurs when connecting to the SDF file through FDO: "An exception occurs to an external component"

 

I saw this sentence on a foreign Forum:

 

As shown in the following error message: how can this problem be solved? Why? Next, let's look at the expert's reply.

"The specified module cannot be found. (Exception from HRESULT: 0x8007007E )"

 

Sorry, I have not found a solution to this error. I don't know, what are the differences between the FDO versions,

My personal summary: FDO3.3 may be better compatible with C # language! This is my personal understanding... If a GIS expert gives a better answer, thank you !!!!

What is the file with the suffix "SDF? What is the purpose?

SDF is an Autodesk file format used to store GIS elements. An SDF file usually contains a group of elements (points, multiline, and polygon ). In addition to geometric coordinate data, each element has three attributes: name, key, and URL entry. SDF allows you to quickly find elements based on the key or space location.
