The problem is, at least in part, with cmd. cmd /? says: If /C or /K is specified, then the remainder of the command line after the switch is processed as a command line, where the following logic is used to process quote (") characters: 1. If all of the following conditions are met, then quote characters on the command line are preserved: - no /S switch - exactly two quote characters - no special characters between the two quote characters, where special is one of: &<>()@^| - there are one or more whitespace characters between the the two quote characters - the string between the two quote characters is the name of an executable file. 2. Otherwise, old behavior is to see if the first character is a quote character and if so, strip the leading character and remove the last quote character on the command line, preserving any text after the last quote character.
This tells me that CreateProcess is not really at fault at all, but instead the fix is to create a different command line. I can think of one of two things: (1) do not have a double quote as the first character, (2) if the program is quoted and there exists an argument quoted as well, replace ' ' with '^ ' everywhere in the program and add a '^' at the end of the program before the quote.
Try using short names to get rid of the first set of quotes. Short names still work, at least on XP. Compare c:\>dir docume~1 and c:\>dir "Documents and Settings" To find out the short names, c:\>dir /x Or one can guess (first 6 characters + "~" + "1", or a higher digit if the 6 characters + "~1" is already used, + "." + first 3 characters of the extension). Try changing the batch file from echo %1 to echo %1 %2 %3 %4 %5 %6 %7 %8 %9 That should work by getting rid of the second set of quotes, at least if the number of arguments is less than 10. This, also, works /c> echo '"c:\Documents and Settings\BBuchbinder\test.bat" "hello world" exit' | u2d | cmd /k c:\>"c:\Documents and Settings\BBuchbinder\test.bat" "hello world" c:\>echo "hello world" "hello world" c:\>exit You can leave off the "/k", but you then get extraneous text from cmd.exe as it loads.
This is a lot of good info, especially since I generally do not use DOS. Thank you.
