关于进程的拒绝访问
进程拒绝访问怎么办？
hModuleSnap = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, dwPID);
int err=GetLastError();
if (hModuleSnap == INVALID_HANDLE_VALUE)
{
printf("创建失败:%d/n ",err);
return (FALSE);
}
代码在这里总是出错，查错误为5，拒绝访问，怎么解决？

回复于 2003-07-21 17:40:49 得分 25 以验证：
BOOL EnableDebugPrivilege(BOOL fEnable)
{
// Enabling the debug privilege allows the application to see
// information about service applications
BOOL fOk = FALSE; // Assume function fails
HANDLE hToken;
// Try to open this process's access token
if(OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken))
{
// Attempt to modify the "Debug" privilege
TOKEN_PRIVILEGES tp;
tp.PrivilegeCount = 1;
LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &tp.Privileges[0].Luid);
tp.Privileges[0].Attributes = fEnable ? SE_PRIVILEGE_ENABLED : 0;
AdjustTokenPrivileges(hToken, FALSE, &tp, sizeof(tp), NULL, NULL);
fOk = (GetLastError() == ERROR_SUCCESS);
CloseHandle(hToken);
}
return(fOk);
}
在你需要的时候使用EnableDebugPrivilege(TRUE);
结束后再调用EnableDebugPrivilege --------------------------------------------------------------------------------------------------------------------------------
