Assigning a double word ptr to string data

[Jim Seekamp]

I'm attempting to assign a string's bytes to a double word array. Here's what I tried that doesn't work:

           dim bc???(1 to lnw???)

           dim ptbc as dword ptr
           dim ptw as string ptr

           ptbc=varptr(bc???(1))
           ptw=strptr(w$)

           ptbc=ptw

I know there is a way to do this, just can't remember how!
Any ideas?

Jim,

ptbc=ptw

just assigns the value of the pointer itself. You need to us @ to assign the thing being pointed to by the pointer.

REDIM bc???(1 TO LEN(W$)\4 - (LEN(W$) MOD 4 <> 0 ) AT STRPTR (W$)

Does not create a copy: Changes to W$ automatically change the values of the elements of bc???() (which just might be the behavior you are after?)

Changes to length of W$ of course require REDIM, but that's true even when you DO copy the string bytes to the integer array.

Thanks Michael -
That's exactly what I was looking for!
