c - What is the value of a unsigned long long in hex -

-

i have variable

unsigned long long latitude = 29.47667;

when converting value array this

    ar[7] = (uint8_t)((latitude >> 56) & 0xff);     ar[6] = (uint8_t)((latitude >> 48) & 0xff);     ar[5] = (uint8_t)((latitude >> 40) & 0xff);     ar[4] = (uint8_t)((latitude >> 32) & 0xff);     ar[3] = (uint8_t)((latitude >> 24) & 0xff);     ar[2] = (uint8_t)((latitude >> 16) & 0xff);     ar[1] = (uint8_t)((latitude >> 8) & 0xff);     ar[0] = (uint8_t)(latitude & 0xff);

then sending server using tcp socket. when sending print values in hex, 0x1d rest zeros.

how send exact value server while converting unsigned long long int.

unsigned long long latitude = 29.47667 doesn't make sense, unsigned long long integer type. variable gets truncated integer 29.

that's why 0x1d, 29 in hex.

Using 'OR' and 'AND' in SQL Server -

-
is using ( condition or condition b , condition c ) the same as ( condition , condition c) or (condition b , condition c) no. first condition is: (condition a) or (condition b , condition c) and second is: (condition , condition c) or (condition b , condition c) you can see difference between them.

c++ - NetBeans Remote Development with additional configuration -

-
i'm trying use netbeans (7.3.1) work on remote project. my configuration following: my local machine windows 7 laptop. doesn't have tools. in particular neither compiler nor debugger. have netbeans ide , putty example. source code, make scripts , (eventually) build results located on remote storage shared across servers , "locals". (i might switch single server storage faster don't think matters @ all.) i'm accessing using sshfs manager . sshfs manager takes server name, path on server, user name , ssh private key. in result mounts directory on server disk on windows. works fine. (although directories, possibly links, represented files in windows explorer, don't know if matters...) netbeans project located on local machine don't think matters , place remotely well. prefer keep "off source" don't have add ignores version control. in netbeans did procedure described in remote developement tutorial . seems successful. netbeans c...
