Hi, i'm trying to create the following code..
The above code, raise a race condition, it overwrites the previous data ( E.G "xmod(z), tmpChar, a,blisted1,xchar2" ) that the previous threads needed, i understand i need to use SYNCLOCK, but it to much to use it, it reduce the speed of the parallel..
Is there a way to enhance this without using the SYNCLOCK??
VB.NET:
sqrt = Math.Ceiling(Math.Sqrt(2549))
a = 0
xchar2 = ""
Parallel.For(1, sqrt + 1, Sub(o)
Dim a, b, c, i, y, z As Long
i = 2
a = 0
If o = 1 Then
b = 1
c = sqrt
Else
b = ((o * sqrt ) + 1) - sqrt
c = (o * (sqrt ))
End If
For y = b To c
a = y
tmpChar = "cat"
For z = 0 To i
xmod(z) = a Mod 26
a = ((a - a Mod 26) / 26)
If InStr(tmpChar, numToletter(xmod(z))) = 0 Then
bListed1 = False
Exit For
Else
tmpChar = Mid(tmpChar, 1, InStr(tmpChar, numToletter(xmod(z))) - 1) & Mid(tmpChar, InStr(tmpChar, numToletter(xmod(z))) + 1)
If z = 0 Then
If check2(numToletter(xmod(z))) Then
xchar2 = numToletter(xmod(z))
bListed1 = True
Else
xchar2 = ""
bListed1 = False
Exit For
End If
Else
If check2(numToletter(xmod(z))) Then
xchar2 &= numToletter(xmod(z))
bListed1 = True
Else
xchar2 = ""
bListed1 = False
Exit For
End If
End If
End If
'---
Next
If bListed1 Then
Debug.Print(StrReverse(xchar2))
End If
Next
End Sub)The above code, raise a race condition, it overwrites the previous data ( E.G "xmod(z), tmpChar, a,blisted1,xchar2" ) that the previous threads needed, i understand i need to use SYNCLOCK, but it to much to use it, it reduce the speed of the parallel..
