Hi X# Team,

See attachment.

Following Robert's instruction, I able to build Explorer Sample in VS 2015.
However, I got runtime error.

"Vulcan.NET Runtime Error". Probably, I am the most hard-assed out there who resist Vulcan invasion. Vulcan Runtime 205 here!!!

Rene,

The error message that you get is probably a little different from the error message that later Vulcan versions get, but the example describes this error.
Did you copy the CATO*.DLL files as indicated on https://www.xsharp.eu/help/example-1-the-vo-explorer-examp.html

Hi Robert,

Just the dll described here: https://www.xsharp.eu/help/example-1-th ... examp.html

I will try again tonight.... I will update you.

Rene,

I copied all DLL in VO redist, but the problem remains...

I will now proceed to some major conversion....

Hi Rene,

Hmm, let's see what's causing this, this should had worked fine. I checked the callstack you sent, the error happens in this line

SUPER(oOwner, FALSE, #CustomerTreeView, #CustomerListView)

because it fails to create the classes CustomerTreeView and/or CustomerListView. In my version of the ported sample, those classes exist correctly in the code and the sample runs fine. Maybe for some reason those does not exist in your sample? Could it be you have modified those classes after exporting them?

If there's nothing obvious like that, can you please zip and send the exported folder to have a look?

I apologize last time, I wrote at the middle of "quote" and my post look so ugly. I have yet to get used to web-based forum that looks like this.

Anyway, I have screenshot of the VS 2015 debug view.

Hope this help also...
I hold my test conversion for now...

Rene,
those dratted icons are missing...
@Chris,
copied the icons from my vo-folder to the new location, changed the path X#,
first it complained, so i added "" around the path to avoid any issue with the space, but now i get a strange result, see attachment.

For good measure, restarted Xide, but the error is still there... :huh:

That is strange.

I will experiment again tonight.

Hi Rene,

Thanks for posting the code, that helped a lot! In short, the problem is that the option in the project settings <Language Tab>"Prefix classes with default Namepsace" is set to True. Set this to False and now the sample will run fine.

The reason why this was causing this problem, is because when this option is enabled, then all the classes in your project get automatically prefixed with the namespace that is provided in the General tab of the Project Options. So in your sample's case, for example the class "CustomerTreeView" was actually getting emitted by the compiler as "Explorer.Sample.CustomerTreeView". But then, in line 109 there is this code:

SUPER(oOwner, false, #CustomerTreeView, #CustomerListView)

which then internally calls CreateInstance() for the above classes. But now the class names are different, so CreateInstance() cannot find them. So another solution could have been to specify the "new" names here:

SUPER(oOwner, false, "Explorer.Sample.CustomerTreeView", "Explorer.Sample.CustomerListView")

(conversion from STRING to SYMBOL happens automatically)

either doing that, or disabling the "Prefix classes with default Namepsace" options (but do not do both!) will allow the code to run as expected.

Also, if you want to compile and run the XIDE version, then you will only need to disable the option <Compiler>/nostddefs: Ignore XSharpDefs.vh, because this file contains the definition for CRLF and you do not want to ignore that.

ps. Con's worry at all about the formatting of your posts, that's no problem at all. Personally I am still trying to get used to posting in a web forum, even after having posted lot's of messages already!

ps2. Karl, I am pretty sure the error message is correct, probably some part of the path you specified is not correct . Can you check again pelase?
