Simple SendMessage Question

[Andrew McKay]

Can someone kindly put me out of my misery with the following?
I need to know how to perform the conversion of an LPSTR to a
LPARAM:

In C/C++ I'd do the following:

SendMessage(hLbox, LB_ADDSTRING, 0, (LPARAM) "Test string")

However in PB it gets upset with the LPARAM parameter. How do
I go about performing an implicit cast?

If you want to use a dynamic string:

DIM sText AS STRING
sText = "Test string"
SendMessage hLBox, %LB_ADDSTRING, 0, STRPTR(sText)

If you want to use as ASCIIZ string:

DIM szText AS ASCIIZ * 256
szText = "Test string"
SendMessage hLBox, %LB_ADDSTRING, 0, VARPTR(szText)

Thanks Jose! It was the StrPtr() function I was missing.

Gosh, it's been some years since I had to pick up a new language
and compiler
