I have several entry validations I would like to do for my forms; but, vba in arcgis does not have built-in "input masks". (Does C# in arcgis offer more straight forward input masking?)
Can anyone offer their solutions or point to online solutions to coding "input masks" and error validation for textboxes in vba/arcgis?
I especially need an input mask and entry validation for a date textbox.
My first code sample below is my attempt at both an input mask and validation for a date textbox; but, there are still incorrect entry's that can slip through; for example 02/31/2011 would be valid). The second code sample is a simple textbox entry validation for length not to exceed a specific value (the maximum value of the table field to which the data will be saved).
Seems like we should have a library of basic form code to share among ourselves.
