are everything nullterminierte Strings, So one Chr$(0) mark the end the Strings!
example for nullterminierten String:
Compile Mark Separation

Declare MeinString$
MeinString$ = blub + Chr$(0)
Addr(MeinString$)re>

with the Addr becomes then the Pointer to the nullterminiertem String transfer.

mean You, that any Strings only as address transfer go? are with XProfan The Strings not automatically nullterminiert? Should still, because too XProfan must still discern, when the end one Strings come is.

Yes, The API knows only 32-bit-Integer as Parameter. in the entrapment of Strings means a Zeiger the first characters one strings. the end desselben becomes through one zero-byte marked. the means though too, that in API-Call in einm String no zero-byte vorkommen must. (there's a few Ausnahmen, where one simple zero-byte in the string vorkommen must and the end through one doppeltes zero-byte marked is.)
The Kennung lpsz means: Long Pointer String Zeroterminated - Zeiger on nullterminierten String.

No Strings in XProfon are in the Normalfall not nullterminiert and can therefore too as much as you want zero-Bytes include. into Bytes to the Stringanfang standing z.B. The length the Strings. (it deals itself around the Ansi-Strings of Delphi.)

sometimes finds one The Bezeichnung vbNullString. is the identical with in XProfan?

there XProfan with one API-appeal with one String-Literal (here: ) which address commit would in this drop means The address on a Leerstring transfer. If to the wants, would But rather, too whom Empty-String with a Nulbbyte abzuschließen: z (this is identical with chr$(0) ).

there's however some API-functions, The with a Zeiger on a Leerstring not so right get by. These expect then simply in lieu of the address the Leerstrings a 0 as mark, that this Parameter not used becomes. i'd means everywhere, where vbNullString standing, simply a 0 hinschreiben:
Compile Mark Separation

hOpen& = InternetOpenA(Addr(INET_CallerName$), opentype&, 0, 0, 0)

now, something schlauer be I already become. but nevertheless still something confused:

In VB find I subesquent appeal of/ one function:

hRequest = HttpOpenRequestA( _
hConnect, POST, Path, HTTP/1.0, _
vbNullString, 0, INTERNET_FLAG_RELOAD, 0)

How Roland writes, becomes with one String-Literal The address transfer, in the obigen example means The address of String POST or. HTTP/1.0 but here without Nulltermination. ought to one in XProfan as a precaution POSTz or. HTTP/1.0z write or does it then without?

Also at Weiterübersetzen be I on the following punched:

InternetReadFile hRequest, Buffer, Len(Buffer), Bytes

InternetReadFile is again a Api function, The but none worth zurückgibt, instead sowohl whom Buffer, as well as Bytes with Values equips. in the Api-Definition becomes Bytes as Long indicated. it'll So one 4 Bytes great worth into written. in the drop give I in XProfan well too The address of Bytes& on, correctly.? In XProfan would The row How follows looks:

InternetReadFile(hRequest&,addr(buffer#),sizeof(buffer#),addr(bytes&))

correctly. so?

(I suppose, The function sizeof gives on, How tall the Buffer dimensioniert watts and not, How tall the itself therein located nullterminierte String is.)

I have straight on some further VB-pages class programs found, of them it itself lohnen would, in XProfan To translate

P.s.: have in the XProfan-Help following Lines found:

eachone String becomes through one Nullbyte (characters with the code 0) exits. On these point can Strings OHNE detour over Memory-Variables on API-functions transfer go, about:

MSGBOX(0, @Addr(cover$), @Addr(Text$), Stil&)

On well german, Strings need I do not extra with a z slip, separate must just The address transfer, there eachone String with a Nullbyte slip becomes. still the standing in the Widerspruch to the, what Roland a little while ago written has. I mean, if I reinen Text have (no Image or ähnliches, I anyhow in a area write would), need I the end not extra To mark. If I do not sure be, whether it itself circa reinen Text deals, ought to one to safety one z append.

I fasse times for me together:
Strings and Buffer go not directly transfer, separate only its Adressen. Ggf. becomes with one Buffer yet The Size the Buffers (Bereiches) mitangegeben, if The Api-function values into write would like. Integer and Long go into most Make directly transfer, unless, The Api-function would like these values give back, then gives one The jeweilige address on, so that in XProfan the worth immediate in the variables drin standing.

vbNullString supplant one on the simplest with the worth 0.

rather is it in the MSDN or in the PlatformSDK nachzusehen.

BOOL InternetReadFile(
HINTERNET hFile,
LPVOID lpBuffer,
DWORD dwNumberOfBytesToRead,
LPDWORD lpdwNumberOfBytesRead
);

lpBuffer becomes one Pointer expects, means The address, siehste on the lp, the same thing counts for lpdwNumberOfBytesRead
The remainder becomes directly transfer, means ByVal, the others name itself in VB ByRef.
into Beschreibungen in the PSDK standing too always explicit what expects becomes!
