using SHFileOperation to create a file

[sambarker123]

Hi all
I am tring to copy a file.The code is as below

int _tmain(int argc, _TCHAR* argv[])
{

string s3,s4;

s3="C:\\test\\to";
s4="C:\\test\\from\\sam.txt";
LPCTSTR ptr=s3.c_str();
LPCTSTR ptr1=s4.c_str();


SHFILEOPSTRUCT s = { 0 };
//s.hwnd = m_hWnd;
s.wFunc = FO_COPY;
s.pTo =ptr;
s.pFrom =ptr1;
s.fFlags = FOF_SILENT;
int i =SHFileOperation( &s );

return 0;
}

The return value of SHFileOperation is 1026.

It works fine if i assign the string directly
say like
s.pTo ="C:\\test\\to ";

I need to convert the string to LPCTSTR
How can correct the above code

Cheers,
Sam

You ned to use your TCHAR mappings thourghout your code:

s.pTo ="C:\\test\\to ";

I need to convert the string to LPCTSTR

That is:

s.pTo =TEXT("C:\\test\\to ");
 
 

Now you have your LPCTSTR.

You need to fix the other places in your code.

Now, you cannot use the C++ string object out in public like this:

string s3,s4;

because it has to be a wstring when you have your Unicode switch set.

I recommend a macro:

#ifdef _UNICCODE
typedef wstring  tcharstring;
#else
typedef string  tcharstring;
#endif
 

and then define you strings as:

tcharstring s3,s4;
 

Remember, you can have no explicit types that change between ASCII and UNICODE.
