MFC Commandline.... Phil.Benson10-Jul-06 21:29 Phil.Benson 10-Jul-06 21:29  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 bum... and I thought I´d got rid of all the bugs Re: MFC Commandline....

George_George10-Jul-06 20:15 George_George 10-Jul-06 20:15  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 Re: how to find the value of a macro? Code_Zombie10-Jul-06 21:00 Code_Zombie 10-Jul-06 21:00  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
