Hallo
i try to create a DB . On the memofield it stops. What do i wrong? This work on VO

aStruct := { ;
{ "IS_FAKTURA","L",1,0 } ,; // LIEFERSCHEIN IST IN EINER RECHNUNG AUFGEFÜHRT
{ "FARBE","C",20,0 } ,;
{ "Id_Liefer" , "C" , 15 ,0 } ,; // LIEFERSCHEIN ID
{ "GEWICHT","C",20,0 } ,;
{ "ID_ARTIKEL","C",10,0 } ,;
{ "BESTELL_NR","C",20,0 } ,;
{ "ARTIKEL1","C",60,0 } ,;
{ "ARTIKEL2","C",30,0 } ,;
{ "ARTIKEL3","C",30,0 } ,;
{ "PRB","N",15,2 } ,;
{ "EINHEIT","C",20,0 } ,;
{ "MWSTSATZ","N",5,2 } ,;
{ "MENGE","N",9,3 } ,;
{ "RAHMENNR","C",40,0 } ,;
{ "MEINTEXT","M",0,0 } ,;
{ "FFONT","C",3,0 } ,;
{ "BLOCKTOTAL","C",30,0 } ,;
{ "DIMENSION","C",30,0 } ;
}

// DBCREATE(cTempFile,aStruct,"DBFCDX",,,,)
DO WHILE TRUE
IF DbCreate(cTempFile,aStruct,"DBFCDX",,,,)

Hi Horst,
for the fieldtype "M" you cannot indicate a field width of 0.
VO ignores this, but X# requires the correct indication of 10.
Wolfgang

Hi Horst,

That's because of the MEMO field, you have specified a length of 0, while this should be 10. But I see that indeed VO works also with zero, apparently it ignores the length you specify and always uses the correct one. WIll log this a a compatibility problem, thanks!

Edit: Well, what Wolfgang said already!

Hallo
Thanks, so i will put 10.

btw why put a length ? its a memofield

We now also support the new FoxPro Memo field which has a width of 4 (it stores the block address as an integer and not as ascii).
So we need to know which type you want.

Hi Robert

Mmm you can see it on the dialect switch i am using ?
btw its written XSharp.RT (in XSharp.RT.dll) Version: 2.6 , so dbcreate () doesnt need a vo dll ??
Horst

Horst,
I'll change the RDD system to look at the type of RDD and adjust the column width automatically.

Robert

Hi Horst,

The XSharp.VO library is very small, only contains a few functions (like Crypt()) and types (like VObject and OleAutoObject) which are specific to VO dialect apps. All the main runtime functionality is implemented in XSharp.Core and XShar.RT, so some VO dialect apps (that do not use the VOSDK) do not even need XSharp.VO at all.

i have a question.
Xsharp shoud be the new xbase language for .net
so the goal shoud be , that all people is slowly switched to the core dialect. and all other like Vo, Foxpro and Harbor shoud be supported for old programs.
my question, is it possible to rewrite my app without any compromise ? so i can use the core dialect and a dbf database. and i dont like also this x86 radiobutton (sounds so old, like i make apps on a win95 computer )
i hope folks you understand what i am asking about.
what i need as a beginner in X#, is a app like ssatutor in pure X#.
Horst

Hi Horst,
let me try to answer: with VO, the life was relatively simple as there were only the VO GUI classes as GUI choice, and DBF databases were the best option.
With pure X#, you have the choice between Windows Forms and WPF, and you have the choice if using MVVM or not (for WPF it seems the best option, whereas in the older Windows Forms world it does not seem to be so used).
What should such a sample application use? And what type of database? These days I would see DBF only as niche database, and any sort of SQL databases as mainstream.
I agree that such a sample application could help a lot, and I thought many times I should provide one, but was always missing the time.
But maybe now that we again have a "hard" lockdown (here in South Tyrol we cannot exit anymore freely as our hospital capacities are exhausted) maybe I will have some time for such a project.
