check if the input text is number or not

[Amincool]

I have a very simple question:
I have 3 input objects in my first page of project
thees inputs must include just numbers (and . for decimals). how can I manage that if the input texts was not numeric then a msg.box appear and if there was just number then jump to the next page. thanks for your helps

Hi you could try this example to get an idea
Have a couple of different functions in Globals
Check input box on key events also

here an example

Here's another example to use subclassing to real-time filter (before the characters are printed). This example also filters the comma and replaces it with a dot, as an example of what you can do. It uses the MemoryEx plugin and the (included in the example) windows.lh resident file.

You can minimize overhead and do this quite effeciently by making use of the native Lua function: tonumber. By inverting its inherent logic, we can create a simple custom function that will detect for numbers (including the decimal point):

Place this in Globals:

function numberRestrict(inputObject)
     local inputString = Input.GetText(inputObject);
     if inputString ~= "" then
          if not tonumber(inputString) then
               Dialog.Message("Input Error", "Invalid input detected.\r\nEnter numbers only.\r\n\r\nEg. 8, 6.5, etc ...");
               Input.SetText(inputObject, "");
               Application.ExitScript();
          end
     end
end

... and this in the On Key event of your Input Object:

numberRestrict("Input1")
