Hi Basile,

Did a quick test and seems to work ok here, there must be some difference that I'm not thinking of. Does this happen with all fieldspecs in your app(s). Can you please send me a VO module .mef (or app) with dbservers from your app to test with it here?


Hi Chris I have the .mef but I ...

Hi,

we've noticed that we lost one information when porting ou database definitons to X# using VOXPorter.

It looks like the "Description" field in VO does get lost and nowhere to be found in the .xsdbs nor .xsfs generated files :

in VO DB designer :

and resulting ported ...

Thanks a lot for your answers !

I will dig into late bound calls using the pragma.

@VR yes I've used the performance monitor with the memory usage to detect the memory leaks, I'll have another go to try to find the bottlenecks

Fun ahead !


Thanks again.

Basile,
ADS should be almost as fast in both VO and X#.
The handling of the indexes is done by the server and not by the client.
The macro compiler could be a bit slower, but that would not explain the speed difference that you're seeing.

Thanks for clearing that


I suspect that your app has a ...

One thing for certain is that for many reasons dbf operations are slower in X# than in VO, so this could be your bottleneck.

Do you have any idea how slower ?
A lot of our customers are on ADS, shouldn't be quite the same as most of the work is done on the server side ?
Is is proportional ...

Hi all,

I'd like to know if anyone already compared app performance with a VO pored app in X#.
Our app is pretty big and ou X# porting is almost complete (always some glitches here and there) so we have the VO app running alongside with the X# one (sharing the same data) for a smooth transition ...

Hi everyone,

is there any plan yet for Xsharp summit 2025 ?


Cheers !

Hi Chris !

and thanks for your answer but my understanding was that if I do pass a NULL to the c# function, then it should use default ?
So you're saying that as null is valid for the string argument, it does not take the default value right ?

I learned something then thanks

Hi and a very happy new year to everyone !

I stumble upon a strange behaviour when calling c# functions from a x# project:

I have a c# function having an optional string parameter with a default value:

public static void DefaultParameterTest(string defautvalue = "default")
{
Console.WriteLine ...

Basile,
If the class is a DbServer subclass then it has to be:

PUBLIC METHOD SetFilter( cFiltre ) AS USUAL

I tried that but then it's complaining about not having a type :
