Silly question, had a lok in the MSDN but could not find any thing that satisfied my curiosity, how long can a command line be? I´m asking because I am passing a path to a file,plus an SQL query to an external process (using create process), so can I expect any problems regarding a very long SQL query...
Thanks in advance
Phil

from stdlib.h on VS.NET
/*
* Sizes for buffers used by the _makepath() and _splitpath() functions.
* note that the sizes include space for 0-terminator
*/
#define _MAX_PATH 260 /* max. length of full pathname */
#define _MAX_DRIVE 3 /* max. length of drive component */
#define _MAX_DIR 256 /* max. length of path component */
#define _MAX_FNAME 256 /* max. length of file name component */
#define _MAX_EXT 256 /* max. length of extension component */
Hope these help

The maximum command line length for the CreateProcess function is 32767 characters

{
char HostName[MAX_NAME_LEN];
struct in_addr *ptr;
gethostname (HostName,MAX_NAME_LEN);
hostent *host = gethostbyname(HostName);
if(host == NULL)
{
ipAddress = NULL ;
WSACleanup( );
return ;
}
ptr = (struct in_addr *)host->h_addr_list[0];
CString str;

Hello everyone,
I am wondering what is the easiest and safest way to find the value of a macro? For example, if I,
#define FOO "value1"
The value of FOO I can get is "value1" and if then I,
#undef FOO
#define FOO "value2",
then the value of FOO I can get is "value2".
thanks in advance,
George

Hi,
I didnt get the question,basically the macros are replaced by the preprocessor,so there is nothing like finding the value at the runtime.
Hope this helps.
Thanks

Thank you Code_Zombie!
Do you mean we can only get the value during compile time other than during runtime?
My question is, during compile time, how can we (developer, other than compiler itself) know the exact value of a specific macro -- which compiler is using -- to avoid mis-defining the value of a macro?
(I know compiler knows the value, but during normal compile stage, it is not exposed to the end user which value is defined to a specific macro, so there may be mis-defined macro value.)
regards,
George

I'm using CSingleLock , When one thread lock an object, and other thread wants to lock that object at that time , The second thread will wait for unlocking by the 1st thread or it just skip that locking code.
If it need to wait, It will automatically wait or have to give code to wait ?
--------------------------------------------------------------------------
CMutex g_m1;
CSingleLock lock1(&g_m1)
- - - - - - - -- - - - - - - - - - - - - - - - - - - -
if (lock1.Lock()) {
m_LockStatus = "Got Lock";
UpdateData(FALSE);
} else {
m_LockStatus = "Failed";
UpdateData(FALSE);
}
}
-----------------------------------------------------------------------------
Thanks to all.
