I downloaded twilight.zip from the internet. It is an excel sheet able to calculate sunrise and sunset created by Keith Burnett. I took the VBA code and incorporated it in Ms Access. In MS access I created a world clock and now I want to be able to display the sunrise sunset times for the relevant time zone as well.
I tested the VBA code via the Immediate window and this gave the correct values for sunrise and sunset. I ‘am able to type a value for glat in the argument. For example 51.5.
Function Sunrise(ByVal day As Double, glat As Double, glong As Double, index As Integer, _
Optional altitude) As Double
When I debug the function to check the value of variable glat it gives a value of 51,5. This is with my regional setting with the comma being decimal separator. If I repeat the same procedure for the English setting with the dot separator it states 51.5 in de debug window. In both cases if gives the correct value for sunrise.
I live in the Netherlands and the DOUBLE value gives me problems. I want to transfer the latitude and longitude to the function. When I type the value with the keyboard directly in the arguments of the sub it displays to correct values. However I want to transfer the value of a combobox’s column to the sub. If I change the column of the combobox to double it display the comma where ms access obvious expects a dot.
I searched the internet and EE. Tried replace, changing string to value and concatenated the coordinates to a dot value and change it to a value. All to no avail.
Is there any way to overcome the regional settings and input the double value correctly.
