MapWinGIS version 5.2.4 64 bit Windows 10, MS Access 365 VBA
Whats my problem?
- I am trying to generate categories, but they don’t appear on the map.
What I am trying to do?
create a map of roads that are classified by proposed maintenance treatments.
Load the 5 treatment categories into the map, and set colors for each treatment
I use the following code to do this:
sf_Lines.Categories.ClassificationField = 4 With sf_Lines.Categories.Add(Treatment) .ValueType = cvExpression .Expression = "[TREATMENT] =" & Treatment .DrawingOptions.Visible = True .DrawingOptions.LineColor = RGB(T_Red, T_Green, T_blue) .DrawingOptions.LineWidth = 5 End With
and after all treatments are loaded, run
I believe the code is working. I exported the Category settings to XML and it appears all my settings are there.
Map0.SaveLayerOptions(0, "Line_Samples.txt", True, "")
