Code updated For 5.20+ (same As StringGadget() with Flag #PB_String_Numeric )

I don't know if someone prior to me has posted something similar on this forum.
This is how you do if your string gadget only should accept numeric characters as input:

Code: Select all

#ES_NUMBER=$2000

ghandle.l=StringGadget(0,10,10,100,20,""); this should input numbers only
flag.l=GetWindowLong_(ghandle,#GWL_STYLE)
SetWindowLong_(ghandle,#GWL_STYLE,flag|#ES_NUMBER); now it should work as wanted

Note that you have to open a window prior to the above code.
Is there an easier way to accomplish the above?

Not really... even Visual Basic programmers have to write procedures to strip
out alpha characters from a numeric text box as they are typed.

number=StringGadget (45, 70,260, 51, 21,"")
SetWindowLong_(number, #GWL_STYLE, GetWindowLong_(number, #GWL_STYLE)|$2000)

It works, but with two very major flaws:

(1) You can't type floats into it (eg: 3.14).
(2) You can still paste alpha text into it.

That's why I said that Visual Basic programmers had to write a procedure to
strip out alpha characters as they were typed (or pasted).
