Hi,

have The honour The first question here to put To can

I work in the moment the data base-system Cheetah
[...]  and the whole
working too terrific. The Dll supported whom Funktionsaufruf through
OLE Strings but too with standard zero-terminierten Strings.
so far so well...

now would like I The Memofelder benefit circa there binäre data (Images)
To Save. there in the suitable function no Memory-Variable
separate only the String transfer becomes is the maximum length Yes on
32767 characters terminable - the langt but not there

If I the right understood have are OLE-Strings roughly said
dynamic Strings The no defined length and have each arbitrary
characters include can (correct me Please) and not of
Profan supported go. -means bad luck had...

really have I me The question so already self answers,
or I have there what overlooking???

unfortunately is the data base no Freeware , but Perhaps
has Yes jmd. interest The whole functions for Profan
umzusetzen - have already a Include written The whom Use
vereinfacht.

now likes itself of/ one ask Why I The Dll at all using:

1. Very small, stood alone
2. Very quick
3. Extensive Suchfunktionen
4. wants me not SQL keep busy

here again short The Spezifikationen:

Max number of records: 2,147,483,647
Max number of fields: 1000
Max character field size: 256
Max numeric field size: 20
Max memo size: Limited by disk space
Max record size: 4000 bytes

Indexes
Max open indexes by database: 100
Max fields for compound indexes: 6
utterly allowable open indexes: 1000
Queries

Max number of conditions: 50
Max sort expressions: 6
Multiuser

Max number of concurrent users: 255

getreu the Motto: what The data base can should, the should tappt im dunkeln then too without Fremdeinwirkung do...
mandatory I you somehow right give.

but how'bout instead of with jangle simply time with Verbesserungsvorschlägen. pieces whom Entwickern simply with, that the with the Memofeldern not all Programmiersprachen functions and question, whether tappt im dunkeln not a function install can, a address and a Längenangabe expects.
then go from the Speicherbereich, on the The address shows, very amount Bytes into Memodatei copies (and Rückweg very so).
the ought to then with all Programmiersprachen functions.

Hi,

Perhaps can you The APIs lstrcpy() and lstrcat() help.
The copy (or. hanging on) a String a Buffer.
otherwise can you Perhaps too MultiByteToWideChar() or WideCharToMultiByte() help.

[/quote:8a80d2de32]
unfortunately No there tappt im dunkeln as Parameter ditto a Nullterminierten String expect and it so automatically gekürzt becomes.
[quote:8a80d2de32]what The data base can should, the should tappt im dunkeln then too without Fremdeinwirkung do...
[/quote:8a80d2de32]
naturally can I expect the everything correct functions damn, so a Sch&$% DB!
Also schimpf I Yes none! (even if itself the Perhaps so reads)

but you have Yes right what about me have again a Mail on whom Support written. I wanted to hold gladly exclude the it on me or
XProfan lying, english Mails verfassen heard namely sure not To my
strengthen, but Why should The not too something To laugh having with the work.

time bad what there happens!

Andernfallst would it well not To plenty desires if Roland quick time even a Support for OLE Strings einbaut

Hmmm, were OLE Strings not these, which with a the Längenangabe begin (number d. bytes) and then with the eigendlichen Content equips are? Perhaps can you the simply a area simulate, hear You?

know Thou what OLE Strings very are? - I nothing very white.

now, if i remember rightly are OLE-Strings nothing moreover as Pointer with a 32bit Header which The length angibt.

you mean means so:

FileData# < contains sinngemäß z.B. whom Content the File
DataOLE# < contains whom simulierten OLE String

Adresse& = FileData#

LONG DataOLE#,0 = @SizeOf(FileData#), Adresse&

means the first 4 byte give The length on and the next 4 The address
the Memory-Variables.

if so then is not. :|

no, probier time 32bit size, and remainder Data.

means

dim b#,8
long b#,0=4
byte b#,4=ord(t)
byte b#,5=ord(e)
byte b#,6=ord(s)
byte b#,7=ord(t)

the Entwicker was trouble well yet uncharted but he's still
quick reacted what about me have the new DLL! with new function!

sometimes ought to one itself integrally simply not zulange so detain whom Error there to search where it not is.

I thanks all The me with this boring Topic helped having...

Hey Primö! can Yes time so NEN ready-kompiliertes part (your exe my I) and the new dll zuschicken. (ifs allows is naturally only).

or quite here post as attachment. would be me gladly time so one Zwischenergebnis standing.

To denne, iF
