HRESULT Warnings (Windows Embedded CE 6.0)
1/5/2010
HRESULT is a return status type used by COM functions to signal success or failure.
There are strict guidelines for how HRESULT should be used. However, these are frequently overlooked or ignored. The Code Analysis tool detects situations where HRESULT has been used incorrectly or has been used in a manner that might cause undesirable results.
For more information about Code Analysis warnings, see this Microsoft Web site.
The following warnings are reported in this category:

warning C6214: cast between semantically different integer types: HRESULT to a Boolean type |
C6215 |
warning C6215: cast between semantically different integer types: a Boolean type to HRESULT |
C6216 |
warning C6216: compiler-inserted cast between semantically different integral types: a Boolean type to HRESULT |
C6217 |
warning C6217: Implicit cast between semantically different integer types: testing HRESULT with 'not'. Consider using SUCCEEDED or FAILED macro instead |
C6219 |

C6220 |
warning C6220 - Implicit cast between semantically different integer types: comparing HRESULT to -1. Consider using SUCCEEDED or FAILED macro instead |
C6221 |
warning C6221: Implicit cast between semantically different integer types: comparing HRESULT to an integer. Consider using SUCCEEDED or FAILED macros instead |
C6225 |
warning C6225: Implicit cast between semantically different integer types: assigning 1 or TRUE to HRESULT. Consider using S_FALSE instead |
