I have 2 extensions for Business Central, one base and one where I am doing the customizations. I have a Enum in the base extension and the base app is currently in the folder of the extension I am working so I think the references are there, I also checked and the enum is there. But when I try to publish my extension it says "Enum not found" Has anyone any idea how to import the enum in AL Programming Language?
Thanks in advance.

I am using the Standalone SDK from ZKTEco for a fingerprint scanner. I need to add some custom functionality.
I've downloaded the SDK along with the Demo project. Now when I try to build the Demo project, I get the following error
"Severity Code Description Project File Line Suppression State
Error CS1061 'CZKEM' does not contain a definition for 'SetUserValidDate'
and no accessible extension method 'SetUserValidDate' accepting a first
argument of type 'CZKEM' could be found (are you missing a using directive
or an assembly reference?)"
I have referenced the zkemkeeper.dll file in my project. I'm using VB 2017 on Windows 10. I've tried to look for Embed Interop Types property but I cannot find it in the properties ofzkemkeeper
How can I solve this issue? Any help would be appreciated.
Thanks
I order to make any project referencing the zkemkeeper compile, you need to register it in the windows system.
You should have received a bat file among the dll files called "Register_SDK" as shown in . This is used to register the zkemkeeper in windows. If not, then you must register it manually.

There is also a starting guide for newbies already written by another member of this community, it´s written in c#.
Best regards.
I created a VS 2010 class library. Marked the assembly for Com Visibility. Signed the assembly with a strong key. Created my class, have my entry point method available.
The library works fine from a test project in C#.
I regasm the class library to gac, via:
c:\windows\microsoft.net\framework\v4.0.30319\regasm testdll.dll /tlb: testdll.tlb /codebase
Include the tlb file as a reference in my VB6 project. I find it through resources 'browse' so its there.
When i try to instantiate the class... its empty. the public method that should be available via the public class doesn't show.
Dim objTest as testdll.testclass
set objTest = new testdll.testclass
objTest.testmethod <--- this 'testmethod' doesn't display in intellisense... nothing does.
In addition i tried calling the 'testdll.testclass' via CreateObject, i get the error "ActiveX component can't create object"
Now i have other projects i've done COM visibility for and i've tried comparing the difference, but i don't see any. I can't understand why it isn't working.
Any clues??? tx very much.
Just use an interface... one you define or to use the [ClassInterface(ClassInterfaceType.AutoDual)]
there are comments online you can find that indicate not to use autodual, but if you control the complete usage of your library, it seems like an 'ok' way to go.
I tried all sorts of ways to simulate / understand why my one project didn't need an interface to be visible by an vb project, without success. i had originally thought perhaps possible that it was because that project implemented an IDisposable Interface (the ONLY interface used in the C# projects that is com visible) but that didn't turn out to be the reason. Anyway I don't want to waste anyone else's time on this. thanks for the responses.

I want to add my own project type based on IronStudio. So,
I downloaded the source for and compiled the latest version of IronPython, then
I created a new Visual Studio Package.
I added the Templates\Projects\MyProject folders, and added a file to it, and set its property "Include in VSIX" to true.
Then modified the main Package class to be derived from IronStudio's PythonProjectPackage instead, and set the ProvideProjectFactory property:
[ProvideProjectFactory(
typeof(PythonProjectFactory),
"Django Project",
"Django Project Files (*.myproj);*.myproj",
"myproj", "myproj",
#"Templates\Projects\MyProject",
LanguageVsTemplate="MyProject")]
public sealed class MyPackage : PythonProjectPackage
And ran it. But MyProject isn't showing up in the project templates. Why not?
The generated .pkgdef file looks like this:

I just want to get the bare bones up and running so I can start overriding some functionality (like the Add New Item dialog).
Update:
Reading my initial analysis once again increases my impression that some of the required components are missing (e.g. a dedicated ProjectFactory) and/or wired up incorrectly - from the MSDN documentation of the ProvideProjectFactoryAttribute Class:
ProvideProjectFactoryAttribute declares that a package provides a project factory.
And further:
If a VSPackage declares that it provides a project factory, it should create the factory and offer it to Visual Studio in the Initialize method of the Package-derived class.
You package is declaring to provide PythonProjectFactory, but (likely) doesn't offer it to VS, rather it is offered by the IronPython package. In turn you are providing arguments within the ProvideProjectFactory attribute list which PythonProjectFactory won't know about when asked for by VS.
Consequently you should at least provide a dedicated ProjectFactory yourself as per the walkthrough, wire up the classes accordingly and see how this turns out regarding the issues outlined below.
Initial analysis:
There appear to be several issues here at first sight - have you followed any tutorial on how to do this? In case, please note that some of those easily discoverable via search engines are outdated still. Either way I'd try working through and/or comparing your result with Walkthrough: Part 1 - Creating a Basic Project System from the MSDN documentation for VS 2010; please note that even this one is claimed to be outdated a bit according to the Community Content section on the bottom of the page.
Here is what I'd look into myself given the code you present, comparing with the walkthrough on the fly for more insights:
You realized already that the duplicate fragment starting with the GUID above PythonProjectFactory doesn't make sense - this is essentially trying to register two packages at once, which, even if allowed at all syntactically (which I doubt), can't possibly work like so due to both being registered with the same GUID [cross checking with the sample file in section Examining the Template Registration confirms this suspicion, as expected there is only one such fragment].
Please note that the GUID in question is the one identifying PythonProjectFactory (as per the respective source code), see below for more on this.
[Guid(PythonConstants.ProjectFactoryGuid)]
public class PythonProjectFactory : ProjectFactory {
Given .pkgdef is a generated file the next question is where this duplication/violation stems from. When two generated artifacts end up with the same GUID the respective definition in the sources is most likely messed up somehow, usually due to copy&paste duplication. Consequently you should verify whether {5cd7435c-7461-459f-80bc-c0c79e9d462f} is defined and referenced as intended, though here might be one or two other causes as well for this, see below.
A Package class needs to be identified by a GUID and the VS wizard generates some already in Guids.cs and references it accordingly on the class definition, however, the following is missing in your fragment [cross checking with the sample fragment in section To register the project template confirms this omission as well]:
[Guid(GuidList.guidMyPackagePkgString)]
public sealed class MyPackage : Package
Likewise it appears incorrect to derive MyPackage from PythonProjectPackage but reference PythonProjectFactory still rather than providing MyFactory as well (including a dedicated GUID), because the latter tells Visual Studio the location of your project template folder [see section Creating a Skeletal Project Factory]:
While it might well be possible to simply reuse all functionality from the base class PythonProjectFactory, inheriting is likely required simply because the factory must have a dedicated GUID too (as outlined in the walkthrough) in order to properly wire up the attribute specified data.
Likely unrelated, but still suspicious is that your two code blocks don't relate, as the Package class definition specifies Django Project Files (*.myproj);*.myproj, yet the result shows My Project Files (*.myproj);*.myproj.
Have you by chance mixed this from different builds or is this really a result of a clean one?
Good luck!

$PackageFolder$.\NullPath may have something to do with it.
Visual Studio includes a refactoring function called "Extract Interface" that generates an interface based on a class implementation.
The extracted interfaces are Internal by default. Problem is, we end up changing nearly all of them to Public.
Does anyone know why it's Internal by default? Better yet, is there a way to customize this to default to Public?
It might work if you change the Visual Studio template for interfaces (I haven't tried that but assume this should work).
For Visual Studio 2008 the template is stored at
"C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\ItemTemplates
\CSharp\Code\1033\Interface.zip"
This is described in more detail in this answer.
I don't have a reference, but I have a wild guess as to why it is internal by default.
Let's say you have 3 projects / assemblies: log4net (a 3rd party API), MyApp.Util, and MyApp.Web (a Web project). Web references Util, which references log4net. Web does not reference log4net, and you want to keep it that way.
Inside of DAL, say you have an internal class, and one of its members references a type defined in log4net. It could be the return type or one of the parameter types of a method, or the type of a property.
Let's say you extract an interface from the aforementioned class, including the aforementioned member that references log4net. Well, if you make that member public (part of a public interface) and reference a type that implements it, you then require that the Web project reference log4net.
By making the interface internal, Web may continue to be ignorant of log4net.
A word or two about project I have to make.
I have a list of products (XML formatted), and I have to make a bar code of that list.
Here are the requirements:
Technology has to be MFC, VS 2005 or VS2008
All functionality must be in one dll
Same solution should have a simple tester for the dll
I will use pdf417. http://en.wikipedia.org/wiki/PDF417 http://sourceforge.net/projects/pdf417lib/
Also, I would like to provide an interface, so that different bar codes can be implemented in future.
For example, my dll has "Write" method which is implemented in a separate file for pdf417 and in a separate file for some other bar code, so that user can choose which bar code to use.
Since I have no knowledge of mfc, I really don't know how to even start. I read some tutorials, created the dll with some dummy method, and then tried to use it in tester application, but no luck.
I know that this is a "needle in a haystack" type of a question, but if someone could help me how to setup/architect this project I would be very grateful.
Thanks,
Marko
I don't see how you benefit from using MFC if your DLL's client is not an MFC app. You are better off using a standard C interface in your exported functions if you want to support non-MFC clients. Just create a Win32 project and choose the project type as DLL, then the wizard will generate some example exported function for you. Follow the examples to create your own export functions.
