Winnt Cmd.exe/c Issue: Bad Parsing Of Filename W/ Quoted Batch File String

Hi! I am working on a program written in C for Windows that calls an external console program and am having an issue: when I call the external program with the path quoted through the cmd.exe utility, cmd.exe says that the whole string is not a valid command or file. Without quotes, the program works properly. I'm using the CreateProcess() function to run the external program, using the /c switch before the filename, passing the utility a file and postfixing "& pause" to the command line to pause the execution upon exit. What could be causing the problem?

 

Most likely you're not escaping the quoted path correctly. It would help if you posted the relevant code.
An example of a properly escaped path is:

Code:

LPWSTR ws = L"\"quoted\\file\\path\"";

 

The following is the command line:

Code:

/c "C:\Emulators\C64\exomizer-2.0.10\win32\exomizer.exe" sfx basic -t64 -x1 -o "compress64.prg" "compress64.prg"&pause 

The following is the code to execute the program:

Code:

static void writecmd (void) 
{ 
        strcpy (cmd, "/c  \""); 
        strcat (cmd, exomdir); 
        strcat (cmd, "\\exomizer.exe\" sfx basic -t"); 
        //itoa (systxt, flags.sys, 10); strcat (cmd, systxt); 
        sprintf (systxt, "%d", flags.sys); strcat (cmd, systxt); 
        strcat (cmd, " -x1 -o "); 
        strcat (cmd, file); 
        strcat (cmd, " "); 
        strcat (cmd, file); 
        strcat (cmd, "&pause"); 
} 

        CreateProcess ( 
                comspec, 
                cmd, 
                0, 
                0, 
                0, 
                CREATE_NEW_CONSOLE, 
                0, 
                lpath, 
                &start, 
                &inf); 
        WaitForSingleObject (inf.hProcess, INFINITE); 
        CloseHandle (inf.hProcess); 
        CloseHandle (inf.hThread);

Does this help?

I didn't know that. Thanks!
