Thread: command line parameters

OK, what i want to do is this: recall a long time ago when half life 1 came out the only way to enable the dev mode was to do this: Appname -Devmode.exe. is that even worth it or should i just not do it cause i tried this:

Code:

if(argv[0] == -DevMode)
{
       cout << "Hello" << endl;
}

but that didn't work :-( also i was wondering if theres a way to set the name of the exe
in the code it self.

Like:


[code]

void setExeName(const char* AppName); and it creates that EXE with that name. i don't mean creating a file with the extention of .exe i mean making the compiler be able to set the name of the exe through code. I hope i'm makling sense

Hmmm, i get an unhandled exception

Code:

"An unhandled win32 exception int Commands-devmode.exe(1040) Just In debugging the exception failed with the following error Just-In-Time debugger not installed.

I guess Dev C++ doesn't have that cause i can't find it, i should be getting my computer back soon so i'll try in VS C++

so i would do:

Code:

for(int index = 0; index < argc; ++index)
{
     if(argv[index] == 1)
     {
            if(strcmp(argv[index], "-dev") == 0)
            {
                     //Statements
            }
      }
}

that's the only way i can think of doing it.........I'm sorry i'm trying to understand this.

Well, i managed to get the error gone but it didn't work still cause i put the command line in the exe file name and still nothing. this is what i did

Code:

  
           for(int index = 0; index < argc; ++index)
    {
            if(index == 1)
            {
                 if(strcmp(argv[index], "-Dev")== 0)
                 {
                     cout << "HELLO" << endl;
                 }
            }
    }

jeez, I can't seem to get it :-p

so a command like arg isn't used like this: app_name -Dev.exe? cause that diodn't work, also, a command line arg is when you would run the command prompt and type that in? again, sorry if i'm not getting it that well, I've used C++ for a long time but i've never tryed to learn to use command line args so i'm just trying to understand

O_o

Code:

appname.exe --args-here

or

Code:

appname --args-here

not

Code:

appname.exe --args-here.exe

I tried to rename the file appname.exe -Dev and it changed the extention.......maybe i should wait til i learn this in a class

O_O

Wow.

You don't rename the file. You execute the application with parameters. This isn't rocket science.

Soma

But...

I've used C++ for a long time

hehe, sorry i was just trying to do like Half life did in the past.......OH BOY! I'm sorry
