Remove Spaces (or other characters) from a String

[George McGinn]

There's a couple of small glitches in this, that you might want to take a look at and fix, @George McGinn.

First, there's the whole need to set the compiler to allow -fpermissive so this will run.  Types don't match properly, so you might want to tweak them a little.

Second is this alters the original string, corrupting it, as shown below:

Code: (Select All)

Declare CustomType Library "removeStr"
    Function __REMOVESPACES$ Alias string_remove_chr (qString$, charValue$)
End Declare

check$ = "This is a string that we're going to check to see how long it would take to remove the spaces from."
Print check$
Print "The length of our test string is:"; Len(check$)
new$ = __REMOVESPACES$(check$, " ")
Print check$, Len(check$)
End

check$ remains the same length as previously, but the left side of it now mirrors new$.  You might want to assign your string to a temp string and process it, rather than process the original as you go along, to preserve it. 

The reqason your value is corrupted is because you need to terminate a variable with CHR$(0). Line new$ = __REMOVESPACES$(check$, " ") needs to be new$ = __REMOVESPACES$(check$+CHR$(0), " ") - It seems that when you pass variables, you need to tell it when it ends. Literals do not have that problem.

Without a NULL terminator, C does not know when your variable ends. So it keeps going.

If you want to, you could leave your code as-is, but do this:

Code: (Select All)

check$ = "This is a string that we're going to check to see how long it would take to remove the spaces from." + CHR$(0)

However, doing the above messes up the QB64 PRINT statement results.
