Как можно программно (в С++) открыть доступ к диску (папке) в win98 (НЕ NT!)?
Заранее спасибо!

См. функцию NetShareAdd().

Смотрю.. и вижу, что:
NT/2000 - supported
95/98 - not supported

(

Это ты наерно в Platform SDK сморишь?
Я вот в MSDN отчетливо вижу:
Windows NT/2000/XP: Included in Windows NT 3.1 and later.
Windows 95/98/Me: Included in Windows 95 and later.
Header: Declared in Lmshare.h (Windows NT/2000/XP) or Svrapi.h (Windows 95/98/Me); include Lm.h (Windows NT/2000/XP).
Library: Use Netapi32.lib (Windows NT/2000/XP) or Svrapi.lib (Windows 95/98/Me).

Еще раз смотрим в MSDN и ... о, чудо

Windows 95/98/Me: The following code sample demonstrates how to share a resource on the local computer with a call to the NetShareAdd function.

The code sample specifies the share_info_50 structure and no password on the share. The sample also allocates and frees the memory required for the information buffer.

#include <stdio.h>
#include <windows.h>
#include <svrapi.h>

int main(int argc, char FAR * argv[])
{
char FAR * pszServerName = NULL;
short nLevel = 50;
struct share_info_50* pBuf = NULL;
unsigned short cbBuffer;
NET_API_STATUS nStatus;
//
// ServerName can be NULL to indicate the local computer.
//
if ((argc < 3) || (argc > 4))
{
printf("Usage: %s [\\\\ServerName] ShareName SharePath\n", argv[0]);
exit(1);
}

if (argc == 4)
pszServerName = argv[1];
//
// Allocate the memory required to specify a
// share_info_50 structure.
//
cbBuffer = sizeof(struct share_info_50);
pBuf = malloc(cbBuffer);

if (pBuf == NULL)
printf("No memory\n");
//
// Assign values to the share_info_50 structure.
//
strcpy(pBuf->shi50_netname, argv[argc-2]);
pBuf->shi50_type = STYPE_DISKTREE;
pBuf->shi50_flags = SHI50F_FULL;
pBuf->shi50_remark = NULL;
pBuf->shi50_path = argv[argc-1];
pBuf->shi50_rw_password[0] = '\0'; // No password
pBuf->shi50_ro_password[0] = '\0'; // No password
//
// Call the NetShareAdd function
// specifying information level 50.
//
nStatus = NetShareAdd(pszServerName,
nLevel,
(char FAR *)pBuf,
cbBuffer);
//
// Display the result of the function call.
//
if (nStatus == NERR_Success)
printf("Share added successfully\n");
else
fprintf(stderr, "A system error has occurred: %d\n", nStatus);
//
// Free the allocated memory.
//
if (pBuf != NULL)
free(pBuf);

return 0;
}

СПАСИБО!
