current dwg file name

waseefur.rahman — Wed, 11 Jan 2017 09:53:07 GMT

Hi,

Can any one guide me how to get the current dwg file name in C++,

By using this below code I am getting the full path with file name,

const ACHAR *dwgfilename = curDoc()->fileName();

but I need only the file name.

How about this:

TCHAR drive[_MAX_DRIVE+1], dir[_MAX_DIR+1], fname[_MAX_FNAME+_MAX_EXT+1], ext[_MAX_EXT+1];
errno_t err = _tsplitpath_s(curDoc()->fileName(), drive, dir, fname, ext);
_tcscat_s(fname, _MAX_FNAME+_MAX_EXT, ext);

That's great,

One more help I need,

After getting the file name,
I need to create a new path with that file name.

Then copy file to that new path,
I have tried with the code below, but it's not working

//source path

const ACHAR * dwgsourcepath = curDoc ()->filename ();

//File name

TCHAR drive[_MAX_DRIVE+1], dir[_MAX_DIR+1], fname[_MAX_FNAME+_MAX_EXT+1], ext[_MAX_EXT+1];
errno_t err = _tsplitpath_s(curDoc()->fileName(), drive, dir, fname, ext);
_tcscat_s(fname, _MAX_FNAME+_MAX_EXT, ext);

//Destination path

const chat *dwgdestinationpath = D:\\New folder + fname [_MAX_FNAME + _MAX_EXT + 1];

//copy file from source to destination

std::ifstream in(dwgsourcepath);
std::ifstream in(dwgdestinationpath);
out << in.rdbuf();

I'm not an expert for std-streams. Don't know whether they work for binary data.

This should work:

TCHAR dwgdestinationpath[_MAX_PATH+1] = _T("D:\\New folder\\");
_tcscat_s(dwgdestinationpath, _MAX_PATH, fname);
BOOL bFailIfExists=FALSE; // set TRUE if you don't want to overwrite existing file
BOOL bCopySuccess = CopyFile(dwgsourcepath, dwgdestinationpath, bFailIfExists);

Great,
Many Thanks ,

one more help Please,

Since "dwgdestinationpath" we are creating from below,

TCHAR dwgdestinationpath[_MAX_PATH + 1] = _T("D:\\New folder\\");

_tcscat_s(dwgdestinationpath, _MAX_PATH, fname);

But I am getting this Destination path from below

kt::CStr sOutput

Also attached the screen shot,

From the coding you provided it copies the dwg file to destination without extension (i.e) .dwg

I would be highly thankful for your help..

Thanks & Regards

I don't understand what I see in your PNG

TCHAR dwgdestinationpath[_MAX_PATH + 1] = _T("D:\\New folder\\");

_tcscat_s(dwgdestinationpath, _MAX_PATH, fname);
...

From the coding you provided it copies the dwg file to destination without extension (i.e) .dwg

I made the assumption that you use fname after the function call

_tcscat_s(fname, _MAX_FNAME+_MAX_EXT, ext);

which appended the extension to fname.

Actually I can't directly enter the path as ("D:\\New folder"), Since it's variable..
I am getting this path from const char* path,

What I Need is I need to add file name to this path.

Then use this path in copy command as below,

CopyFile(dwgsourcepath, path, bFailIfExists)

Hope you got it..

From your PNG it looks as you want to take the directory from sOutput.str(). I can't see what type sOutput is. You wrote that you get the path as const char*. So you have to convert it to TCHAR*. The easiest way to do this is to use CString, because it's construtor works with both: char* or wchar*:

TCHAR dwgdestinationpath[_MAX_PATH + 1];
CString csPath(sOutput.str()), csBackslash(_T("\\"));
if (csPath.Right(1) != csBackslash) // append '\' if required
    csPath += csBackslash;
_tcscpy_s(dwgdestinationpath, _MAX_PATH, (LPCTSTR)csPath);  
_tcscat_s(dwgdestinationpath, _MAX_PATH, fname);

Or just use CString everywhere to make it more readable:

CString dwgdestinationpath(sOutput.str()), csBackslash(_T("\\")); 
if (dwgdestinationpath.Right(1) != csBackslash) // append '\' if required
	dwgdestinationpath += csBackslash;
dwgdestinationpath += fname;
