How to Create Directory and Subdirectory?

I want to create directories using CString variable "C:\backup\drivers" from an Edit Box.

Using CreateDirectory() only works with "c:\backup".

Some functions I found can create both directory and subdircetory only with CString such as "c:\\backup\\drivers", but will not work with "C:\backup\drivers".

Another function in my application only works with "C:\backup\drivers", but not with "c:\\backup\\drivers".

Is there any function which can create "C:\backup\drivers"?

Thanks a lot.

then use yourstring.Replace("\\", "\\\\") to make it two slashes

you should use CreateDirectory directory by directory:

Code:

---

while (yourstring.Find("\\") != -1)
{
    // Create the next directory until the next slash
}

Thanks for your suggestion. I tried the code, but it doesn't work.

Here is my code.

m_loct is CString Variable, c:\backup\drivers in an EDit Box.

CString dir;
dir = m_loct;
dir.Replace("\\", "\\\\");
WriteDirectory(dir);

But it doesn't work. IF I just use the following code:

CString dir="C:\\backup\\drivers";
WriteDirectory(dir);

both directories were created.

I test after the code dir.Replace("\\", "\\\\");
I found dir is C:\\backup\\drivers

But directory was not created.

What's wrong?

'\' symbol is a command character IN C/C++ LANGUAGES that is used to set some unwritable characters- SINGLE CHARACTERS- like '\n'. To set a SINGLE CHARACTER '\' you should write in C/C++ double '\', and in the resulted string, for example, "\\", there would be only one '\'. Try to out this string ans look at this. So, if you write a path IN SOURCE FILE using double '\', you are really writing path with single '\''s. If you write in source single '\', you are likely to do a mistake, because the '\' characters and the following ones would be some unusual single characters.

ghm...
So, If you will implement some input, user would enter for example "C:\myfile.ext", you will receive the same result as if you declarated this string in your source file like this:

Code:

---

char *str="C:\\myfile.ext"

---

There is another way, you can use Shell function: SHCreateDirectoryEx. You do not need create directories from outermost to innermost. This function automatically creates parents directory if they do not exist.

There is no such function as WriteDirectory? Where did you get this function? Did you write it? Better use quangnt suggestion.

Anyway using smth like dir.Replace("\\", "\\\\"); is wrong in principle...

Guys, Thank you very much for your replies.

I finally got it. Now it works well.
