Problem right clicking many files

[OM3]

I have some code that I can execute on many files.
The files are all CSV files.

So I can do this: mycode.exe abc.csv xyz.csv pqr.csv

I have a batch file with this code:

Code: Select all

mycode.exe %*

So I put this in my SendTo folder.
I right click many files in some other folder...
And my code works a treat! JUST how I need.

PROBLEM: on 2 laptops, when I select multiple files and right click, it ONLY sends JUST one file.
DAMN!

These 2 laptops are cheaper non powerful ones - that's the only difference I can think of!
All are Windows 10 with latest updates.

What am I doing wrong?

Thanks.

Hello OM3,
Your endless list of paramaters can be processed simply one after the other.
Step 1:
Start the command with the first parameter.
Check whether there is a second parameter
If yes - change the position of the parameters with shift and go to step 1
If no - end the batch.

You can get help via call /? and shift /?
Now the question is whether your program one after the other edited or whether your program opens itself twenty times or more?

There are two things I can think of.

1) Ampersand bug:
If the full name of a file doesn't contain spaces but do contain an apersand then the parameter comes in unquoted and causes an error.

2) String limit:
%* will be expanded to a space-separated string of pathes. Note that every passed file contains the whole path of the file. The limit of a string (and thus, of a command line) in batch is 8191 characters.

thanks for the replies guys
i intentionally left out details

the code that gets executed is something like:

Code: Select all

"d:\folder 1\my folder 2\abc def xyz\more spaces\my code.exe" "d:\folder 1\folder abc def\zy ze\ab23c.csv" "d:\folder 1\folder abc def\zy ze\bbbabc.csv" "d:\folder 1\folder abc def\zy ze\aaabc.csv" "d:\folder 1\folder abc def\zy ze\c.csv" "d:\folder 1\folder abc def\zy ze\ac.csv" "d:\folder 1\folder abc def\zy ze\a.csv"

all i want is DOS to give me this.
And it does!!!!!!!!
it works perfectly - only on 2 laptops it just doesnt work.
i have a pause at the end to see what gets executed.

what gets executed is:

Code: Select all

"d:\folder 1\my folder 2\abc def xyz\more spaces\my code.exe" "d:\folder 1\folder abc def\zy ze\ab23c.csv"

@aGerman i wasnt aware of the & bug. probably is a problem. maybe i'll look into making sure it's not later. for now all OK.

string limit: i think i'll be ok with that. good to know though.

@pieh-ejdsch the problem is getting the string and not the execution. the execution of processing one after another is done by my code.

is there any other way i can get many string names into a dos prompt by selecting and right clicking and using sendto?

thanks

anyone?
still stuck with this problem
it's so annoying

would i use powershell to do similar?
never used before ever. but cant be more than one line of code like the dos version?

thanks

it works perfectly - only on 2 laptops it just doesnt work.

... and the question is why it doesn't work on these two laptops?
So what you can try is prepending an ECHO to the command line and append a PAUSE to your code only to figure out what you even get in %*.

@aGerman, thanks for the reply.
It executes with only one file name.
I can select many files and right click.
I'm not 100% sure, but it either takes the item right clicked or the first in the list and passes through.

I'm forced to execute manually on a DOS prompt.

I'm sure it's a Windows related behaviour.
I just want to figure out a way round.

Any ideas?

Thanks.
