Limiting what can be put into an Edit text box

[RhodriC]

Is there a way to specify that an Edit Text box can only recieve input
from certain charicters (just as numbers)

I know it would be perfectly possible to make a sub to verify what has
been put into the text box is numeric values, but stopping the user
from putting non-numerics in in the first place would be ideal.

My current code for the dialog box looks like this

Dialog
Title "Geo-coding Rasters"
Control StaticText
Title "Horizontal Distance of Map (meters)"
Position 10, 10
Control EditText 'EditText Box
Position 130, 10
ID 23
Control StaticText
Title "Vertical Distance of Map (meters)"
Position 10, 30
Control EditText 'EditText Box
Position 130, 30
ID 25
Control Button 'Button "Choose File"
Title "Open File"
Width 40 Height 20
ID 24
calling fileInfoBox
End Sub

With ReadControlValue() functions later on to get the value of the
inputs.

Thanks in advance

I don't believe there's anything in the edittext control's callback
functions like "onChange()". You could do this through Windows APIs though.

A slightly different approach is to create a numeric keyboard dialog. The
downside is that you have to mouse-click numbers, the upside is no apis and
total control over what numbers etc you want to use.

A sample is attached.

Hi All,

Does anyone know where the fill patterns for MapInfo are now held (in v11). They used to be in the mires.dll file, but don't appear to be there anymore. I need to add some custom fills on a colleagues computer and not having much luck at the moment!

Thanks!

Nice approach, Tony!

Could that be extended with the use of Alt keys, so that the user could enter the numbers by holding down the Alt and typing the numbers?

If you add an "&" in front of the text on the buttons, you can use Alt + the text on the button to active the button.

And so you don't need the mouse. You just have to hold down the Alt key and press the key you want.

Thanks Peter, I’ve tweaked the code to deal with ALT keyins; however I had to change the +/- sign to a – sign to use the ALT form.

I’ve also added a reset and return0 button, as well as adding a statictext item at the top to allow a note from the user to be displayed.

 

To get round the problem of underbars added by pressing the ALT key making some of the buttons difficult to read; especially the . and – buttons, I have added a full set of numeric keys and  ‘. < and –’ as hidden keys below the equivalent (no &s) keypad keys. There are still odd problems with the ALT format but the keys are far more legible.

'

'    Code to create and manage a data input dialog. Both mouse click and ALT+ key is supported.

'    It is restricted to:    Numerals 0-9

'                            Decimal point "."

'                            Minus sign "-" is used to change sign

'                            Less Than "<" is used to delete the last character

'

'    The dialog routine is declared as:

'    declare function numeric_keypad(byval h as string) as float 'h is string such as "X Distance"

'    The note string is shown as a static text at the top of the keypad.

'    The current input value is shown as a statictext control

'    The return value is converted to float format.

'    Users can use the ALT Key with the keyboard or click on characters

 

'    It is supported by sub keyin

'    It needs a module wide string t_string that is used in the dialog and support code routines.

'    (dim t_string as string ' t_string is used to store data that is common to all the modules.)
