TextEDParam compile error in CONNECT works in SS3

C++ Namespaces

I am getting this compiler error: error C2065: 'TextEDParam': undeclared identifier

C++ namespaces are used throughout the SDK.  struct TextEDParam is defined within the DgnPlatform namespace (see BEGIN_BENTLEY_DGNPLATFORM_NAMESPACE in that file).
Either use the namespace at the beginning of your file (see the SDK examples) or qualify the struct name with the relevant namespace e.g. DgnPlatform::TextEDParam.

Look at the SDK examples.  Bentley have defined a number of macros that help declare a namespace and use a namespace: see DgnPlatform/DgnPlatform.h. You'll see ubiquitous statements like this near the beginning of many source files...

USING_NAMESPACE_BENTLEY_DGNPLATFORM;

Could this be a similar case? error C2065: 'UnitInfo': undeclared identifier 

It looks like it is defined in <DgnPlatform\DgnFileIO\UnitDefinition.h> but that does not fix the error.

The only SDK example I see that uses this type is steel which does not compile for me. 

Hi Ken,

maybe. But without context and more details, it's hard to say.

Did you read a description of this error? It provides hints what can cause this problem.

You must change your thinking from C to C++, where - as Jon wrote - everything resides in (some) namespace. So to include the header is not usually enough, and you must ensure the proper namespace is used. MicroStation SDK makes this process simpler through predefined USING_NAMESPACE_xyz macros.
