Roger already gave you the solution, but if you want to find more info on the subject, you can google for "forward declaration" (that's how it is called).

of course.but the whole code is too long,i would paste a snip of it.
Because these days,I am test iTunes libaray.Here,"iTunes.exe" is valiable everywhere,such as apple.com,its lastest version is 7.3.2.4 on that web site.I use 6.0.0.18
I use such code to import the COM of iTunes:

#import "iTunes.exe"
..
..
//in .tlh file:

//error code here<br />
 //<br />
    // Wrapper methods for error-handling<br />
    //<br />
<br />
    ITSourceKind GetKind ( );<br />
    double GetCapacity ( );<br />
    double GetFreeSpace ( );//error here<br />
    IITPlaylistCollectionPtr GetPlaylists ( );

in .tli file:

//error here<br />
inline double IITSource::GetFreeSpace ( ) {//error<br />
    double _result = 0;<br />
    HRESULT _hr = get_FreeSpace(&_result);<br />
    if (FAILED(_hr)) _com_issue_errorex(_hr, this, __uuidof(this));<br />
    return _result;<br />
}

And if delete the error statement,no errors.
If there is no errors,I also want to know how to use the new file.
Thank you very much.

GOOD LUCK.

How to locate Application Folder in MFC?

Hello guyz,

I have a problem, hope someone can help me.
When I create setup files, I declare taget location for Application Folder of the software. But at the start of the program I need to access the said folder for a file (*.ini) that i included in the setup.
For now, what i do is to state the default location. For example, c;\Program Files\Application Folder.
Problem arises when user change the target location of the folder and my program can't locate it anymore.
Is there a way to locate wherever the user placed the Apllication Folder?
How will I implement it in the source code?

Increase the font size.

Another option is to set an image list. I.e Create an image list and set it to the list control. The height of the list control will increase to the height of the image list.

Simple %s issue help

Hi all,

wsprintf(c,"%s%i %s%i %s%i %s%i",day,stLocal.wDay,month,stLocal.wYear,stLocal.wHour,":",stLocal.wMinute,":",stLocal.wSecond);

Why can't I get the value of stLocal.wHour, stLocal.wMinute and stLocal.wSecond?

My output appears as "Mon 4 Dec 2006" I cannot get the time in.

Help me modify my code.

thanks,
Jj

Maybe try casting those WORDs to ints when you pass them to wsprintf().

Also, your parameter list order and types needs to match the order and types of the format
specifiers (they don't match in your example code).

wsprintf(c,"%s%i %s%i %s%i %s%i", day, stLocal.wDay, month, stLocal.wYear, stLocal.wHour, ":", stLocal.wMinute, ":", stLocal.wSecond);

You have 8 specifiers, 9 passed arguments

The order of the 8 specifiers is

string
int
string
int
string
int
string
int

The order of the passed arguments is

string
int
string
int
string
string
int
string
int

Note that you're also passing the wrong types if those int arguments are WORD sized.
"%i" expects an int, not a WORD. If those are WORDs you are passing, cast the arguments
to ints (e.g. "(int)stLocal.wDay")
*edit* Or if they are WORD arguments, you can pass them like you are, but change the
format specifiers to "%hu" instead of "%i"

The passed arguments corresponding to each "%s" format specifier MUST
be a pointer (const is OK) to a char (const char *).

You can also use %hu to print a WORD value.

Hello,

I think it should be written this way.

wsprinf(c,"%s %i %s %i %i:%i:%i",day,stLocal.wDay,month,stLocal.wYear,stLocal.wHour,stLocal.wMinute,stLocal.wSecond);

Hope this will help.
