Double to CString Conversion

[Jason Craig]

I'm working on a small project in order to learn MFC. I want to
convert a double to a CString to place in an edit box. I've tried to
cast the double to CString with no luck. I tried to convert the
double to a string and then cast it to a CString with no luck.
Am I missing an easy fix to this?

If you have a solution for me please let me know

Thanks,
Jason

Use CString::Format:

From MSDN:

CString str;
str.Format(_T("Floating point: %.2f\n"), 12345.12345);

The only data type that can be directly converted to a CString are the
string pointers char *, LPSTR, LPTSTR , etc.

The function you are looking for is CString::Format(..).
It is equivalent to the printf(...) function taking the output format and
list of arguments, writing the fromatted string to the CString object.

A simple example:

CString str;
double num;

num = 65.0;
str.Format("The value is: %f", num);
MessageBox(NULL, str, "",0);

The %f will be replaced by the string representation of your double.

See the documentation for CString::Format(...) and
printf(...) for full details of how to use the string formating functions.

also see sprintf(..) for writing to a string buffer.
