Unless you find someone here who knows Delphi, you will need to give an indepth description of what that code is doing before you can get a decent answer.
Explain the type Vchar
Also the function StrAlloc
Thanks,
Tom

hi there Tom,

Pchar is an ANSI (8 bit) character.
StrAlloc allocates a buffer for a null-terminated string and returns a pointer to its first character.

The only 8 bit data type in VB is the byte data type. This will only return a number from 0 to 255.
I do not know what a null terminated string is, so I cannot really help you there.
You may need to find someone who knows both languages.

I don't know if this helps, but, VBA has some constants:

vbNullString
vbNullChar

there's another one that may be what you want

vbNull

Hi vvershas,

I only know a little about Delphi.
The character sequence type "String" used by Delphi is original with Delphi.
A StrAlloc function secures a memory.
So I GUESS only you have to do it with vba is

Dim LibName As String * 500
Dim Transbuff As String * 970

May be.....but I think that I do not need to carry out such usage by VBA.

hi Colo,

that code has worked fine thanks!
it does appear that Vb doesn't need specific code to do this.

cheers
