RTF Object - Replace Selection

[idnewton]

Why does the RTF object's Replace Selection action trigger (and input the text) even if nothing is selected? Because there's no way to test whether or not text is selected, and there's no way to test how many of a single character exists in the RTF object, I don't see any way, for example, to change every "a" in the text to "c".

Is there a work-around for this, or is it a known bug?

Create a new condition from the Special object named Compare two general values.
Take the first value from the Rich Edit object: Text > Get selection
To know if something is selected you need to get the lenght of this string variable, so put it inbetween the Len() expression.
Then set the comparison to different and the second value you can leave 0.

So your condition should be Len(GetSelection$( "Rich Edit Object" ) ) <> 0 then something is selected.


The Rich Edit isn't a string manipulator. If you want to count or change (single) signs you can use the String Parser object.

At first you have to use Set source string. Then you can receive the number of substrings of one kind (here "a") exists in this string using the expression numberOfSub( "String Parser", "a" ).
You also can change easily all "a" into "c" using the Set source string action again including the expression replace$( "String Parser", "a", "c" ).

Just play around with the String Parser a bit. It can do a lot of string manipulation.
