Error and Success Codes

Windows CE .NET

DirectShow returns error and success notifications (return codes) to applications in the form of HRESULT values. A return code's LOWORD portion is the return code itself, in hexadecimal format. After you obtain the return code, a call to the AMGetErrorText function returns the code's text description. The COM Win32 HRESULT documentation for the Microsoft Windows SDK contains more information, including how to use the FAILED and SUCCEEDED macros to test return values. It also contains information on the structure of COM error codes.

The following table shows some of the typical COM error and success codes that DirectShow returns.

Value Description
E_FAIL Failure.
E_INVALIDARG Argument is invalid.
E_NOTIMPL Method is not supported.
E_POINTER NULL pointer argument.
E_UNEXPECTED Unexpected error.
NOERROR No error. Numerically equivalent to S_OK.
S_FALSE Success. Condition was FALSE.
S_OK Success. Numerically equivalent to NOERROR.
S_TRUE Success. Condition was TRUE.

The following table contains DirectShow-specific error and success codes in numerical order. Return codes beginning with VFW_S_ indicate success overall. An operation might partially succeed and still have a successful return value. For example, VFW_S_SOME_DATA_IGNORED indicates that a file was rendered by ignoring some of its property settings. Return codes beginning with VFW_E_ indicate an error, while those beginning with CTL_ (Control Error Codes) pertain specifically to the Microsoft Windows Media Player Control. This table does not contain all possible return values; the return codes shown apply specifically to DirectShow. DirectShow-specific return codes also appear in Vfwmsgs.h in the DirectShow SDK Include directory. If you encounter an error not listed here, the error code might appear in another source, such as a list of COM or Windows 95/98 errors. For example, Microsoft Visual C++® users can find COM or Windows 95/98 errors in the Winerror.h include file.

C/C++ programmers receive error codes in complete (32-bit) hexadecimal format. Microsoft Visual Basic® programmers, on the other hand, will see only the decimal equivalent of the error code's first 16-bit portion. This value appears in an error notification dialog box or in the Err object as a run-time error. If the error is not in the following list, you must convert the decimal number to its hexadecimal equivalent, and then look for the error as described previously. Note that the error's hexadecimal version will be a maximum of four digits long; to find the error, match the last four digits of the hexadecimal code in the error code list to the converted run-time error.

Return code Description Hexadecimal value Decimal value
CTL_E_ILLEGALFUNCTIONCALL The syntax in the function call was incorrect. 0x800A0005 5
CTL_E_OVERFLOW The result is too large to be represented in function's return type. 0x800A0006 6
CTL_E_OUTOFMEMORY There is insufficient memory to perform the requested operation. 0x800A0007 7
CTL_E_DIVISIONBYZERO The function attempted to divide by zero. 0x800A000B 11
CTL_E_OUTOFSTRINGSPACE There is insufficient string space to perform the requested operation. Certain operations (copying, for example) involve temporary strings that use up string space. 0x800A000E 14
CTL_E_OUTOFSTACKSPACE There is insufficient string space to perform the requested operation. Each thread has its own stack while other resources, such as heap memory, are shared by all threads in the process. You must specify how much memory to allocate for a separate stack for each additional thread your program needs. The operating system will allocate additional stack space for the thread, if necessary, but you must specify a default value. If the operating system cannot allocate the necessary space, you receive this error. 0x800A001C 28
