LPTSTR to float

[paper67]

I am using VC 6.0. I am writing an MFC application where I use strings with the _T("") macro.(Character set neutral). Is there any way to convert from a LPTSTR to a float value. I noticed that the function _ttof does not exist in VC 6.0. Does anybody know how this conversion can be done. Thx.

How about the old standby, sscanf? There is also a wide-character version, swscanf. If you've eliminated the whitespace around the string-represented floating-point value, then the following will work:

// input: CString sData

float fValue;

// sscanf will return the number of items pulled out of the string
int nResult = sscanf((LPCTSTR)sData, "%f", &fValue);
if( nResult != 1 )
{
// Didn't find a floating-point value. Take corrective action...
}

wcstod() contained in <stdlib.h> ~RaGE();

That's the one I need. Thx a lot.
