Hi acamar,
Below is the error I've encounter modify the codes under exifwork
a = WindowsApplication.exifwork.Rational cannot be converted tp 1-dimensional array of windowsApplication.exifwork.rational
Public
Function ToRational(ByVal
value As
Double)
As Rational()
Dim N
As
Double = value
Dim D
As
Double = 0
Dim S
As
Double = 1
If N = N \ 1
Then
Return
New Rational(Convert.ToInt32(N), 1) <--a
End
If
If N < 0
Then
            N *= -1
            S = -1
End
If
Do
Until N / 1 = N \ 1
            N *= 10
            D += 1      
Loop
        D = 10 ^ D
Dim divisor
As
Integer = gcd(N, D)
        N /= divisor
        D /= divisor
        Convert.ToInt32(N)
Dim R
As
New Rational(Convert.ToInt32(N), Convert.ToInt32(D))
Return R <--a
End
Function
also in the function setpropertyrational3 the method(PutInt32 is not declare).. what is the declaration type of that and where do i put the declaration?
We're close.. i really appreciated your Help.. :)
