SYMPTOMS

When you try to compile a Microsoft eMbedded Visual C++ 3.0 or eMbedded Visual C++ 4.0 application, you may receive one or more of the following compiler error messages:
error C2065: '_com_issue_error' : undeclared identifier
error C2065: '_com_issue_errorex' : undeclared identifier

CAUSE

This issue occurs because the application uses the #import statement. The #import statement functionality is not supported in eMbedded Visual C++.

WORKAROUND

To work around this issue, follow these steps:
  1. In your application, open a common header file that contains the #import statement. For example, open the StdAfx.h file.
  2. Insert the following function prototype declarations before the #import statement.
    void _com_issue_error(HRESULT hr);
void _com_issue_errorex(HRESULT hr, IUnknown* pUnkn, REFIID riid);
#import "<sometypelibrary.tlb>"
  3. Save the header file.
  4. Open a source file that references the header file that you opened in step 1.
  5. Use the following code sample for the _com_issue_error and _com_issue_errorex functions in this source file. For example, your code may be similar to the following code sample.
    #include "StdAfx.h"

void _com_issue_error(HRESULT hr)
{
    //Insert a custom implementation, such as the following.
    TRACE( _T("Caught unhandled COM exception!\n") );
}

void _com_issue_errorex(HRESULT hr, IUnknown* pUnkn, REFIID riid)
{
    //Insert a custom implementation, such as the following.
    TRACE( _T("Caught unhandled COM exception!\n") );
}
  6. Save the source file.
  7. Compile your application.
