did you correctly provide the .lib file to you linker settings ?
|
|
|
|
|
yes, all the lib files needed for the function is given in the settings of the VS 6.0.. as per the msdn winmm,lib is the lib file needed for that and still the problem exist. also two more header file is needed for the function is also included.

did you try a C linkage ? because your symbole seems to be mangled...

if u don mind, could u please tell how to use c linker

extern "C"[^] before the name of the method in the declaration in the header
|
|
|
|
|
the function i mentioned in the error is a inbuilt function for handling the mic's and all should i use extern for that also, if so hw?

man, your _imp_mciSendCommandA() function if declared in a header file, right ?
then prepend its declaration with a extern "C"... like this for instance :
extern "C" int _imp_mciSendCommandA(int);
|
|
|
|

sorry for troubling u again , Actually i'm not declaring that function in my code...i'm just using that function, where the function is declared in Mmsystem.h(inbuilt header file)...
i use this function to open the mic,close the mic and for recording..
syntax of the function in mmsystem.h
WINMMAPI MCIERROR WINAPI mciSendCommandA(MCIDEVICEID mciID,UINT uMSG,DWORD dwparam1,DWORD dwparam2);
sorry for the trouble..please reply

How? Saying you did it, and doing it right, are not always the same thing.

I was writing some code using IShellFolder to get the file information from the operating system. I could get information like file DisplayName or TypeName from SHFILEINFO structure returned by SHGetFileInfo. The thing is I also need some other attributes like FileSize, LastModified/access time etc. In addition for local disk identifiers, I'd like to know the total size and free space attributes. I think either there is another interface for retrieving those information or I've got into a wrong way.
Many thanks in advance.

 True. I was a bit worried that this message was going to be degraded to NextNextNext page. People who want to be helpful won't have a chance to read it.

So have you tried using GetFileAttributesEx()?

Thanks for your reply.
No. I implement this function by using the IShellFolder interface. When accessing files, I don't really know the logical display name. Therefore, instead of using the display file name or directory, I use an ITEMIDLIST originated from Desktop Item to represent a 'file':
LPITEMIDLIST lpi;
SHFILEINFO sfi;
SHGetFileInfo((LPCWSTR)lpi, 0, &sfi, sizeof(SHFILEINFO), SHGFI_PIDL | SHGFI_TYPENAME);
SHGetFileInfo((LPCWSTR)lpi, 0, &sfi, sizeof(SHFILEINFO), SHGFI_PIDL | SHGFI_SYSICONINDEX | SHGFI_SMALLICON);
This can help me to enumerate anything under an ITEM(file/folder/disk...) and find the target sub-item in a faster way.
But as you can see the definition of SHFILEINTO structure doesn't have some information like file size/access time/disk space that I am retrieving.
typedef struct _SHFILEINFO {
HICON hIcon;
int iIcon;
DWORD dwAttributes;
TCHAR szDisplayName[MAX_PATH];
TCHAR szTypeName[80];
} SHFILEINFO;

Can't you just use the GetDisplayNameOf() method to convert the PIDL to an actual path/file name (that can then be used with GetFileAttributesEx())?

You got me. That seems to be the solution. Thanks for your help.

Do I suffer from a performance issue if the displayed file list is fairly large by using this conversion. I am trying it.

Kaushik,
I could easily give or direct to sample code for this. But, this is very basic stuff. And I don't want to spoil you.
Learn to use google and other powerful tools on web. I'm advising you this for your development.
