How to pass multiple commands arguments in visual studio?

Question

I am working on a compession/decompression project using the LZMA SDK.

The main program contains some arguments that I must use to run the application

To run it from the command line, I use :

./LzmaUtil.exe e input.elf output.elf

I'm using VS 2013 , so i have added e in.elf out.elf to the commands arguments, I rebuild the project (the executable file in generated) but nothing seems to happen when I press RUN.

Note that I have the input.elf in the debug folder were the .exe is present there, and the , the flag e is used to compress the file and output.elf is the compressed file.

The main function contains :

int MY_CDECL main(int numArgs, const char *args[])
{
    char rs[800] = { 0 };
    int res = main2(numArgs, args, rs);
    fputs(rs, stdout);
    return res;
}

The complete source code is available at : http://www.7-zip.org/sdk.html

Debugging :

With no arguments at all I get :

The program '[5284] LzmaUtil.exe' has exited with code 0 (0x0).

With the arguments I have mentionned I get :

The program '[5284] LzmaUtil.exe' has exited with code 1 (0x1).

so something is happenning !!!

With breakpoint at the main I get :

numArgs 4   int
args    0x007eaca8 {0x007eacbc "E:\\1PFE\\LZMA\\LzmaUtil\\Debug\\LzmaUtil.exe"} const char * *

Any help will be appreciated, thanks.

What happens if you put a breakpoint at the beginning of main? What happens if the Command Arguments field iks empty? – Phagocyte

@MichaelWalz thanks , I added the debugginf part , it seems that the arguments are well recognized because the variable args contains 4 but i didn't understand the line below – Baal

args[0] points to "E:\\1PFE\\LZMA\\LzmaUtil\\Debug\\LzmaUtil.exe", args[1] points to "e", args[2] points to "in.elf" etc. Pretty basic C stuff. – Phagocyte

@MichaelWalz yes i know this but i don't get any output !!! – Baal

you did not give the complete code, the link goes to LZMA SDK. – Catullus

@Frankenstein if main receives the command line arguments correctly, then the problem is somewhere in main2. – Phagocyte

@MichaelWalz don't thing that there is a problem in the source code , that's because when running the generated application from command line it works just fine – Baal

@Frankenstein well, step into main2 and you'll find out. This should be too hard. – Phagocyte

ok let's see c = args[1][0]; using the warch i get 'Ì' as a value !!! but it must be e – Baal

@Frankenstein and after char *p` = args[1], what does p`point to ? – Phagocyte

` Read 0x00cfa080 {lzmaUtil.exe!FileSeqInStream_Read(void *, void *, unsigned int *)} int (void *, void *, unsigned int *) *` but for *p it tell me that it's undefined – Baal

@Catullus the source code is very long ! yes the LZMA SDK contains the complete source code – Baal

Does the output window show anything useful? (View -> Output -> Show output from: Debug) – Luben

Answer 1

The output was empty because I had put the file in the debug folder which is the same folder as the executable.

However, when I put the file in the parent directory (or the solution folder), it finally worked.

You should make a well formatted answer for your question. – Piker
