CString to char - possible??

I have a class which inlcudes this line for the function -

inline CString GetFile() {return File;}

I am trying to get data in from a dialog list box, using the OnDblClick() this is the code as it stands.
Essentially I have a template filename

(c:\dave......setup.exe)

and the object selected has a method which gets the filename. I want it in the middle of the startpath string. (startpath will be startpath+filename+program)


char startpath[80]("c:\\dave\\");
char program[90]("setup.exe");
char path[100];
CDataObject *pObject;
pObject=0;
path=(pObject->GetFile());
strcat(startpath, program);

spawnl(P_WAIT, startpath, startpath, NULL);

I can zip the whole thing to you if this doesn't make any sense, but i need to get the File ( which is a string, and append it to the startpath variable.

Cheers

You need a null terminated version of the CString object. I think you can get it with the CString::operator LPCTSTR, but as you know, I don't use MFC.

From the help...

>>>
CString::operator LPCTSTR
Use this casting operator to access the null-terminated C string contained in a CString object. No characters are copied; only a pointer is returned. Be careful with this operator. If you change a CString object after you have obtained the character pointer, you may cause a reallocation of memory that invalidates the pointer.

Syntax
operator LPCTSTR ( ) const;
<<<

...edit...

that :o should be a ":" followed by a "o".. Damn smilies crap!

adrianxw is completely right, you can use operator LPCTSTR.
In fact, it will be used automatically for you if you give a CString
object where a const char* is needed.

Alternatively you can use the Format function to do this:

CString strPath;
CString strMiddlePart;

strMiddlePart = GetYourStringFromSomeWhere();

// Format works like sprintf
strPath.Format( "C:\\Dave\\%s\\setup.exe", strMiddlePart );

// conversion to const char* [= LPCTSTR] called automatically
spawnl(P_WAIT, strPath, strPath, NULL);

adrian, you can turn off the smilies. See:

Also, if you use the "code" tage you shouldn't have that problem, and you can even keep the smilies.

>>> you can turn off the smilies

I was aware I could turn them off for me, but was not sure that turning them off for me would affect my posts when viewed by others, (i.e., when I preview I see ":" "o", but someone with smilies sees :o).

I am also aware of the code tags, which I use when posting code sections, however, the code tag can make phat messages which annoy everyone, so for one or two lines, I tend not to bother.
