i want to make a program that creates directories using the ascii number 255 on the desktop. to do this i need to know how to do the following. i need to do this using dos because windows doesnt understand the ascii number 255.
use the ascii number 255 in a md command.
change the directory the dos prompt is pointing too.
Under windows, use 160 for the same effect :)
ye but how can i make do it using a c++ program. that way it would be automated.
i dont understand how thats different from just assignning a number to it?
and no it didnt work i got a error.
when i try this i get a error something about assertion. its supposed to make a directory using the ascii character number 255. also how can i change the directory that dos prompt is pointing to?
#include<iostream.h>
#include<conio.h>
#include<windows.h>
int main()
{
system("md haha" + (char)255); // The c_str() returns a const char*
return 0;
}
Cstrings won't concentrate with + operator. You have to use strcat to concentrate Cstrings, or you can use a string class.
to get easy away, you can use the following trick with escape character:
system("md haha\255");
alright, kedaman, that was what I was searching for, and that's why I used my weird solution
ye but i need it to be the ascii character number 255 ur exampe makes a directory called "haha-"
the ascii character 255 looks like a underscore in windows.
as parksie said, dos 255 == windows 160
ye but isnt windows not supposed to be able to read that character so when u try to delete or open the folder it says it cant be found? how come when i do this:system("md haha99\160"); is creates a directory, but i can still open it.
what exactly does character 255 do? Isn't that the invisible trick character from dos? You were able to open those folders, but it was hard to identify thm.
character 255 isnt understood by windows. if u go to dos prompt and make a directory using that character windows wont be able to identify it, open it, delete it, move it, etc.
It can, it's just interpreted as 160.
For example, create a folder with 255, then access it from windows using 160 - you get the same folder.
This sounds kinda like a bug I found in IE...
I connected to my FTP (using IE) and tried to download something, and I got an error saying the file could not be found...
So I logged in to investigate and I found that there was a space at the beginning of the filename. Once I removed it, I could download it fine.
I guess IE trims spaces from the beginning of filenames. It is a UNIX server so its easy to put spaces at the beginning or end of filenames.
