I am trying to concat a string and a single/float into a string like...

num# = 0.1
s$ = "Hello world " + num#

The error is "types incompatible".
I can't find any function or operator like + or & that works.
I am using the trial version of DBP.
I come from a Visual Basic background.
Thanks for your help.

wrap num in STR() function
you can't conctenate a string and a number
remember the end result will be a string

You need str$()

s$ = "Hello World " + str$(num#)

In VB6...
If you use str() then it returns a variant.
If you use str$() then it returns a string.
I do know that VB6 has many functions that are either
with $ or with out, like mid(), mid$() that work that way.
I have seen performance tests and the $ always works much faster.
any who...

correct because a string is using 2 or 4 bytes, where a variant is using 16 always - because basically a variant needs to hold whatever the user tries to stuff in it like a catch-all. that is crap! Thank god vb.net did away with all of this. Now everything is an object, including every variable you define. The variable will inherit the underlying class so say you make

Dim strMyVar as string

Then you could immediately use

strMyVar.Trim, or .mid() or .Format(), or whatever base methods were inherited from the underlying string class...
