Check overlap in hourly intervals

Navigation
0

Currently I have the need to compare if a section in hours overlaps with another stretch of hours, the truth is that I'm getting a mess and I can not see what is not right, I attach what I have done to see if you see the error:

  • The stretches are HoraIni-HoraFin and stretchFrom-stretchTo

  • are whole numbers

  • a stretch for example from 1 to 3 and the other from 3 to 6 are not considered overlapping 

    • If ((tramoDesde < HoraIni And HoraIni > tramoHasta) Or (tramoDesde < HoraFin And tramoHasta > HoraFin) Or (tramoDesde >= HoraIni And tramoHasta <= HoraFin)) Then
    Solapados = True
End If

    I imagine that in the end it will be a detail or something in the comparison

    There is a library in CodeProject that is in charge of reviewing this and other things

    I have not used it but it has a good reference

    There is a very simple formula to check if two periods overlap: 

    int HoraIni = 3;
int HoraFin = 6;
int tramoDesde = 1;
int tramoHasta = 8;
bool solape = HoraIni < tramoHasta && tramoDesde < HoraFin;

    Edit

    Sorry, it was VB.NET: 

    Dim HoraIni As Integer = 3
Dim HoraFin As Integer = 6
Dim tramoDesde As Integer = 1
Dim tramoHasta As Integer = 8
Dim solape As Boolean = HoraIni < tramoHasta AndAlso tramoDesde < HoraFin

    Read bytes from a socket in java Why does? with-faces-redirect = true change the value?
