Thread: delteing a file...I got it just need help...

Alright I have delted a single file but I want to try and delete a whole directory with files in it.

Here is the code I got so far...

Code:

//Lots o headers please don't comment on them

#include <iostream.h>
#include <conio.h>
#include <windows.h>
#include <iomanip>
#include <fstream.h>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <shellapi.h>

using namespace std;



int main()
{    
    typedef struct _SHFILEOPSTRUCT    //SHFileOperation structure?
    {
        HWND hwnd;
        UINT wFunc;
        LPCTSTR pFrom;
        LPCTSTR pTo;
        FILEOP_FLAGS fFlags;
        BOOL fAnyOperationsAborted;
        LPVOID hNameMappings;
        LPCTSTR lpszProgressTitle;
    } SHFILEOPSTRUCT, *LPSHFILEOPSTRUCT;

    
    _SHFileOperation(_SHFILEOPSTRUCT);    //deletes file
}

yes yes I know tons of headers not sure wich ones I need. (Basicly my test headers)

ok so I got alot of non filled out junk. Can someone help me with that?


Edit: I really don't need them filled. I just need maybe 1 or 2 filled out to see how to properly fill them out.

First, don't put the leading underscore. The function is called SHFileOperation, according to MSDN and Google. Second, you shouldn't need to define the struct yourself.

Ok. According to MSDN (found by searching on Google), what you want is:

wFunc = FO_DELETE
(?)hwnd = NuLL
pFrom = "path\filename.ext\0path2\filename2.ext\0path3\*.* \0";
pTo = NULL
etc.

It's the same as filling out any struct; read which member does what, fill it with what you need, and pass it to the function.

ok alright first time I'm doing something like this.

So far this is what I got...

Code:

//Lots o headers please don't comment on them

#include <iostream.h>
#include <conio.h>
#include <windows.h>
#include <iomanip>
#include <fstream.h>
#include <stdlib.h>
#include <stdio.h>
#include <math.h>
#include <shellapi.h>

using namespace std;



int main()
{    
    typedef struct SHFILEOPSTRUCT    //SHFileOperation structure?
    {
        UINT wFunc = FO_DELETE
        (?)hwnd = NuLL
        LPCTSTR pFrom = "path\filename.ext\0path2\filename2.ext\0path3\*.*\0"
        LPCTSTR pTo = NULL
        FILEOP_FLAGS fFlags;
        BOOL fAnyOperationsAborted;
        LPVOID hNameMappings;
        LPCTSTR lpszProgressTitle;
    } SHFILEOPSTRUCT, *LPSHFILEOPSTRUCT;

    
    SHFileOperation(SHFILEOPSTRUCT);    //deletes file
}

the headers never caused probeblems for me yet when I do the testing stage. But anways. Can I leave some of the things just like they are.

Like one of them only returns true if so and so happens. Do I do anything with them?


and here is my error log. (I get 2 errors)


C:\Documents and Settings\Alex\Desktop\test.cpp In function `int main()':
22 C:\Documents and Settings\Alex\Desktop\test.cpp syntax error before `?' token
25 C:\Documents and Settings\Alex\Desktop\test.cpp:23 [Warning] unknown escape sequence '\*'
32 C:\Documents and Settings\Alex\Desktop\test.cpp syntax error before `)' token


Edit: the error before `)' is in this line: SHFileOperation(SHFILEOPSTRUCT); //deletes file


Thank you for all of your help.

Rune: My post was intended to let you know what goes in what member, i.e. how to fill the struct in. You weren't supposed to copy and paste, as you can probably tell by now. In fact, if you just look at what I posted, the (?) means "I'm not sure about this one", you'll notice that I made a typo and put "NuLL" instead of "NULL", didn't put semicolons on the ends of the lines.

And, looking at your 'updated' code again, I see that you're redefining the structure still, and also you're trying to initialize the structure members in the prototype, which you can't do (you can only do it in a constructor). And you still shouldn't be redefining the structure, because then you're essentially giving the function something that it wasn't meant to take. What you want is something more like this:

Code:

SHFILEOPSTRUCT sfos;
sfos.wFunc = FO_DELETE;
sfos.hwnd = NULL; //(?)
etc.
 
SHFileOperation(&sfos);

[edit]And yes, the \ should be \\. Oversight on my part.

Have you learned about structures yet?
The tutorial has a section on them, if you haven't read about them yet. 'sfos' is short for SHFileOpStruct, and is an object of type SHFileOpStruct, which is already defined in another header - which is why I said you shouldn't be defining it yourself.

>>error were I tried to initialize
Once you've read about structures, you'll (probably) know why you got these errors. In case you don't, it's because you can't initialize variables in a structure definition - either make a constructor for the structure and do initialization in that, or manually fill the members in each object you create. In this case, it's the latter, since you're not defining the structure yourself.

I've never had problems with folders making themselves read-only automatically...
