Hello Sir,

I need help...
I try to create WASAPI application and include ks.h and ksmedia.h on my 
project, I got the link error message as below,
How to setting the m_wfx.SubFormat = KSDATAFORMAT_SUBTYPE_PCM; without any 
link error? This setting is work on MS Visual Studio 2005. Is a bug on 
BCB2007?

Thanks for any comments,
James

Code End*/

You did not include the .lib file that actually defines the contents of 
KSDATAFORMAT_SUBTYPE_PCM.  However...

... you cannot use VC++ static libraries in Borland projects, so you will 
have to define the contents of KSDATAFORMAT_SUBTYPE_PCM in your code 
directly, ie:

    // KSDATAFORMAT_SUBTYPE_PCM = 00000001-0000-0010-8000-00aa00389b71
    const GUID KSDATAFORMAT_SUBTYPE_PCM { 0x00000001, 0x0000, 0x0010, {0x80, 
0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71} };

No.  It is merely an incompatibility between Borland and Microsoft 
compilers.

Thanks Remy,

More questions,

Which .lib need include?  I can not find about ksmedia.lib in BCB2007 
library directory.

    DEFINE_WAVEFORMATEX_GUID(WAVE_FORMAT_PCM)
DEFINE_GUIDSTRUCT("00000001-0000-0010-8000-00aa00389b71", 
KSDATAFORMAT_SUBTYPE_PCM);

Could you provide me more detail about define this GUID? I try it can not 
work.

KSDATAFORMAT_SUBTYPE_PCM is defined in ksuser.lib, which cannot be used in 
BCB projects.

There is no such file to begin with.

> I try it can not work.

Did you try undefining the original KSDATAFORMAT_SUBTYPE_PCM?

    #undef KSDATAFORMAT_SUBTYPE_PCM
    const GUID KSDATAFORMAT_SUBTYPE_PCM = { 0x00000001, 0x0000, 0x0010, 
{0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71} };

Otherwise, you will have to give it a different name, ie:

    const GUID my_KSDATAFORMAT_SUBTYPE_PCM = { 0x00000001, 0x0000, 0x0010, 
{0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71} };

    m_wfx.SubFormat = my_KSDATAFORMAT_SUBTYPE_PCM;

Either way, ignore the original #define macros, they don't work without the 
.lib to back them up.

It's work now, without link error.

Thank you,
