The best solution I can see right now: write a very small dll (in C or C++) with only one function. The function should look like this:
void Convert(LPCSTR tpszDestString, LPCSTR tpszSourceString, int tnLength)
{
float lnAFloat;
double lnADouble;
//-- Copy the contents of the source string
// other the destination number.
// This will "convert" to numeric...
//-- Write the number as string into the dest buffer.
if (tnLength == 4)
{
memcpy((void*)&lnAFloat, (void*)tpszSourceString, 4);
sprintf(tpszDestString, "%f\0", lnAFloat);
}
else
{
memcpy((void*)&lnADouble, (void*)tpszSourceString, 8);
sprintf(tpszDestString, "%f\0", lnADouble);
}
}
I haven't tested this code, but it should work... maybe with some bug fixes... :)

> I'm using low level functions to read (import) a binary file (I think it was created with C/C++). Of course, every thing I read becomes a character. Is there an easy way (I mean a function or something like that) to "cast" a 4-byte character to a VFP Flotant point variable, and a 8-byte to Double?
