Porting Vulcan Net to XSharp

[Juraj]

Hi All

I was porting a small app from VulcanNet 2.0 to XSharp. The app moves the data between the DBF files and the tables in MDB file.
In most cases, I repeat these two errors:


1. Field 'WindowName.components' is never assigned to, an wil always have its default value null

2. The type or namespace name 'dbServer' coould not be found........

Hi Juraj,

The first one is just a warning and you can workaround it by going to the designer.prg file where "components" is declared and change the declaration from

PRIVATE components AS System.ComponentModel.IContainer

to (just add the assignment)

PRIVATE components := NULL AS System.ComponentModel.IContainer

About the second thing, can you please check that the reference to VulcanVORDDClasses.dll still exists in your project references? If it does, then you probably just need to go to the Project settings, in the Language page and enable the option "Enable Implicit Namespace lookup".

Hi Chris

thank you for the advice, especially for dbServer, I had to go into the property and change "Enable implicit ...".

Hi All,
In October 2018 I ported the Vulcan app to XSharp, the client installation was OK and the app worked well.
Build with the current XSharp version at that time.
It was necessary to make some update in the application. After build the application in my computer(with Win10) work OK.
In customer computer does not start. It appears in Task Manager and closes after a few seconds without any error message.
Customer have a HP ProDesk 400 with Windows 7 Profesional.
Versions Windows, .Net ,Visual Studio and XSharp are attached.
The problem is only with the application in Vulcan dialect , the test app in Core dialect runs fine.

Hi Juraj,

I do have a Win7 machine to test with, can you please send me the app to test it, EXACTLY in the form that you send it to the customer?

Hi Juraj,

Thanks, unfortunately this did not give much info, but as I explained by PM, the problem is most likely a (vulcan) dll mismatch, please check what I told you in private. Also make sure the customer is not running your app from a network drive. (it is possible to do that, but he will need to provide specific rights to the app/folder to do that).
