Is it possible for strings to contain Chr(0) characters?
At the moment the following returns 0 instead of 10... but
I need a string to contain Chr(0).

Code: Select all

For r=1 To 10
  a$=a$+Chr(0)
Next
Debug Len(a$)

I don't think it's possible for strings to contain null characters as these are reserved to terminate a string, you probably have to use a memorybuffer to get what you want...

Ah, okay. I was trying to use a string simply because I want to
use ReplaceString to change some data in a string... is there an
easy way to do a search/replace in a memory block? Or is this a
good request for a future command?

I did a small procedure a while ago that search and replace data in a memoryblock, you can find it on the resource site under the snippet section, it's called "findandreplacemem". With some modifications you can customize it to your needs...

Thanks, I worked it out but I'll take a look at your version.
