Copy a Folder

May 21st, 2008

I am trying to Copy a Folder that consist of many files to another folder with a new Name.
I know how to do with files but if I write:
System::IO:: Directory:: I cant find any ::Copy Members here.
Is it possible to Copy a folder "C:\\Folder1" and at the same time rename that folder to "C:\\Folder2" that also will consist the files inside the folder.

For Files I do like this, Is Copy with folders very different ?

System::IO::File::Copy("C:\\TextFile1.txt", "C:\\TextFile2.txt");
System::IO::File::Copy("C:\\TextFile1.txt", "C:\\TextFile2.txt");

Here is an example of how to copy all the subfolders and files to a new destination folder. Looks like you are using managed code, so I don't know how to use unmanaged win32 functions in managed programs.

#include <windows.h>

using namespace std;
 
int main()
{
    SHFILEOPSTRUCT sf;
    memset(&sf,0,sizeof(sf));
    sf.hwnd = 0;
    sf.wFunc = FO_COPY;
    sf.pFrom = "d:\\masm32\\*.*";
    sf.pTo = "d:\\masm33";
    sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI;
 
    int n = SHFileOperation(&sf);
    if( n == 0)
    {
        cout << "Success\n";
    }
    else
    {
        cout << "Failed\n";
    }
}

{

    memset(&sf,0,sizeof(sf));
    sf.hwnd = 0;
    sf.wFunc = FO_COPY;
    sf.pFrom = "d:\\masm32\\*.*";
    sf.pTo = "d:\\masm33";
    sf.fFlags = FOF_NOCONFIRMATION | FOF_NOCONFIRMMKDIR | FOF_NOERRORUI;

    int n = SHFileOperation(&sf);
    if( n == 0)
    {
        cout << "Success\n";
    }
    else
    {
        cout << "Failed\n";
    }
}

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

You can't convert a std::string to a LPCSTR, you'll have to convert it manually. This can be don with the std::string memeber c_str() So change this:

C++ Syntax (Toggle Plain Text)

    sf.pFrom = ss;
    sf.pTo = st;

to this:

 Help with Code Tags 
 C++ Syntax (Toggle Plain Text) 
    sf.pFrom = ss.c_str();
    sf.pTo = st.c_str();
    sf.pFrom = ss.c_str();
    sf.pTo = st.c_str();

And it should work!

Next time if you post code use code-tags.

Here's the MSDN page for SHFileOperation. At the bottom of the page are all the error-codes (return values). So what value does it return in your case?
Print out the value of 'n' in the else statement to find out and thus find out what went wrong.
