Hi to all.
I'm having problems when I put '#include "imapi.h"' line in my app (using IMAPIv1 for writing data on CD)
But the moment I do so and compile several errors appear, all warning some tag structure redefinition. E.g.
c:\program files\microsoft sdk\include\propidl.h(198) : error C2011: 'tagCABSTR' : 'struct' type redefinition
I've download Feb2003-SDK ant put it on top of the Tools->Option->Directories, but didn't help!
Anyone know what to do?

I added the file to one of my projects and it compiled fine. What does the file look like where you added it?

You mean you added line not File?
I created dialog where user can add several files/folders in an listctrl and then record them on CD.
Now, I'm trying to write on CD using IMAPI v1.0 but the moment I include imapi.h
and try to compile errors begin line up. Example:
c:\program files\microsoft sdk\include\propidl.h(144) : error C2011: 'tagCAUB' : 'struct' type redefinition

Should I try to disable this .h file?
I followed 'CD burner' article (for vc7, i'm using vc6 all the same) where states:

<br />
1. Include imapi headers "imapi.h" and "Imapierror.h"<br />
<br />
#include "imapi.h"<br />
#include "Imapierror.h"<br />
<br />
2. Declare your IMAPI variables.<br />
<br />
IDiscMaster *pDiscMaster=NULL;<br />
IJolietDiscMaster *pJolietDiscMaster=NULL;<br />
IEnumDiscRecorders *pEnumDiscRecorders=NULL;<br />
IDiscRecorder *pDiscRecorder=NULL;<br />
IStorage* pStorage = NULL;

but not for me!
THX

the sdk is from Feb2003, should i dawload new (please send me a link if so)

These are one in the same. The #include preprocessor directive does add/insert the contents of the file at the point where the directive appears.

What does the file look like where you added it?

You need to get in the habit of including all header files that you did not create (e.g., imapi.h) in the stdafx.h file. No, it's not required, but you'll save yourself a lot of aggravation.

Thanks, I'll try that.
I thought that putting stuff in the stdafx.h causing program build last longer, I have that habit with something which I need in a few places. But I'm recording on CD in one place so i thought I can include imapi.h there.

I did what you recommended, included files in the stdafx.h and same errors occur:

I did it!!!
No compile errors no more!
I've put include files i stdfax.h then I played some with Tools->Option->Directories property (put WindowsPlatformSDK ver Feb2003 to top) and suddenly no more errors on compile!
One BIG thanks Laugh | :laugh:

to everybody who helped me (especially David Crow ). But no time to rest guy's soon I'll be back with new stuff and bug you some more, but I think you wont mine me
THANKS

P.S.
I hope I'm not going to ask you any more about this topic Unsure | :~

Compare times

Hi,

I need to compare times which are strings. There is a structure for time. I don't have idea about that.

Can u help out to compare times which are strings.

Thanks

You can:
(1) Parse the strings and compare the respective integer values obtained.
(2) Transform your string data (maybe via parsing again) to an opportune object (such a CTime instance if you're using MFC) and then using related members to perform comparison.

Hi,

I found one function strptime which converts string to time.I have included time.h and string.h header files . Even then i am getting the error 'strptime identifier not found;

RE: rewind the wmv file in direct show

If you are in VC++, you can get the strings for the time like that:
CTime time = CTime::GetCurrentTime();
CString szTime = time.Format ( "%A, %d.%B.%Y, %H:%M:%S" );

The CTime is a class and have methodes like:

GetTime Returns a time_t that corresponds to this CTime object.
GetYear Returns the year that this CTime object represents.
GetMonth Returns the month that this CTime object represents (1 through 12).
GetDay Returns the day that this CTime object represents (1 through 31).
GetHour Returns the hour that this CTime object represents (0 through 23).
GetMinute Returns the minute that this CTime object represents (0 through 59).
GetSecond Returns the second that this CTime object represents (0 through 61).
GetDayOfWeek Returns the day of the week (1 for Sunday, 2 for Monday, and so forth).

If you are in c++ then use the struct time_t (in < time.h >) and isollate every member of the struct to compare them.

Greetings.

Do you mean play in reverse or position to an earlier time?

Some filters aren't capable of playing in reverse. Check the capabilities of the streams.

I mean to play in reverse i check
DWORD dwCaps = AM_SEEKING_CanSeekAbsolute | AM_SEEKING_CanSeekForwards | AM_SEEKING_CanSeekBackwards |AM_SEEKING_CanPlayBackwards;

HRESULT hr=g_pSeek->CheckCapabilities(&dwCaps);
is true . but still when i write code
g_pSeek->SetRate(-1.0);
graph could not play in reverse .

CheckCapabilities() returns true? That's not a proper capabilities check - actually if all the
capabilities you check for are available, it should return S_OK, which would be FALSE.
Regardless, the method returns an HRESULT, not a bool.

You should check something like this:

DWORD dwCaps = AM_SEEKING_CanSeekAbsolute | AM_SEEKING_CanSeekForwards  
                      | AM_SEEKING_CanSeekBackwards | AM_SEEKING_CanPlayBackwards;
 
HRESULT hr=g_pSeek->CheckCapabilities(&dwCaps);
if (hr != S_OK)
{
   // Not all the capabilities were present
 
   if (dwCaps & AM_SEEKING_CanPlayBackwards)
   {
      // can play backwards
   }
   else
   {
      // can NOT play backwards
   }
}

if (dwCaps & AM_SEEKING_CanPlayBackwards)

can playback . but when i set rate
g_pSeek->SetRate(-1.0);

but is not playing in backbard . it just stop.
can you suggest me more refinement
