View 3 RepliesI'm studying chemistry and wanted to make a quick app for studying the periodic table. What I have is 36 text boxes. I have a structure that can hold each of the 36 element's info, and an array with 36 instances of the structure.
Example:
Dim Elements(37) As Element
Structure Element
Dim strSymbol As String
Dim strElementName As String
Dim strNumber As String

When I mess with it, sometime the text boxes will fill in, but randomly and the comparison between the input text and the info stored in the data structure never compare correctly. 90% of the time the structure data is showing a null.

View 4 RepliesAfter experimenting around with DevExpress controls and adding them to my form, Custom mask do not seem to work on the MaskedTextBox. If I place a custom mask and debug, I get a null reference exception.
It seems to be the maskedTextBox's mask property that is doing this. I have tried setting the mask through design and by code. However, neither way works.
My question is, is it possible to use a TextBox as a maskedTextbox? To be able to format it? I need the user to enter in hours, minutes, seconds like hh:mm:ss or 00:00:00.
Here's the error I get:
"NullReferenceException was unhandled. Object reference not set to an instance of an object."
