regsvr32 filename.ax
I just see it said something installed successfully,but what's the whole story?
COM that is widely used in Windows relies on registration. A component will provide type libraries, interfaces and classes. Each of these are defined by a GUID to uniquely name them. COM components can also defined ProgID's that are kind of shortcuts to the unwieldy GUID's.
All this information is stored in a special registry hive on the computer named HKEY_CLASSES_ROOT. Use RegEdit.exe to view it. In particular you can find type libraries in HKEY_CLASSES_ROOT\TypeLib, interfaces in HKEY_CLASSES_ROOT\Interface and classes in HKEY_CLASSES_ROOT\CLSID. Some of the information in the registry will contain the path of the actual DLL with the component allowing Windows to locate and load the component when it is requested.
When you install a COM component it is necessary to create the correct registry information. By convention the DLL can provide two exported functions:
DllRegisterServer
DllUnregisterServer
When you execute RegSvr32.exe MyComponent.dll the RegSvr32.exe executable will attempt to call DllRegisterServer in MyComponent.dll. The DLL is then supposed to create all the necessary registry entries to allow the component to be used.
In a similar way you can use RegSvr32.exe /u MyComponent.dll to unregister the component. That will remove all the information previously added to the registry.
Windows relies heavily on COM and it is very important that COM registrations are up to date. Unfortunately there is nothing that blocks you from deleting an already registered COM component. This will leave dangling pointers in the registry pointing to the no longer existing DLL. You can't even unregister it since it no longer exists.
Another problem is when two different applications requires different versions of the same component. The registry can only point to one of the two versions, and this may cause one of the applications to fail.
Microsoft has created fixes for these problems. It is much better to provide an installer for the COM component that is able to repair and uninstall the component if it has been deleted. You are also able to create side-by-side installation of the same component in different versions.
It basically calls into your dll (named filename.ax in this case) and call its "DllRegisterServer" method.
In the case of directshow filters, it might "register" those filters in the windows registry so that directshow knows about them.
ex: https://github.com/rdp/directshow-demo-audio-input-open-source/blob/master/acam/virt_audio_all.cpp#L698 calls
https://github.com/rdp/directshow-demo-audio-input-open-source/blob/master/acam/virt_audio_all.cpp#L631
Though there are more simple versions out there.
regsvr32 registers DLL's and EXEs into the Windows Registry (usually COM Type Libraries, Class IDs, Interface IDs etc). You can use regedit to navigate the registry.

I've segregated my WinUI 3 application into different layers: Application, Infrastructure, Presentation etc.
And all the projects have targets: net6.0-windows and I want to move it to the Uno Platform.
So, I've added a new target: net6.0
And at this moment the problem arises:
Type [WinUI] component already defines a member, called InitializeComponent or some problems with binding.
Is it possible to make such type of library with targets to net6-windows and net6.0?
For the Windows app project itself, you need to use net6-windows, as that provides additional dependencies specific to Windows app projects. All other libraries (non-app projects) can then use net6.0.
Regarding the specific error message, you are getting, the reason might be the generated files have some kind of conflict - you can try deleting the obj and bin folders and rebuild.
The easiest way to make existing Windows app support Uno would probably be to create a blank Uno solution and then migrate the code there (as the solution has already the required setup for platform-specific projects prepared and you can then just add your code.
Uno also provides templates for cross-targeted libraries, so you might be able to use similar approach. The one linked is for "UWP" solution however, so to make it WinUI, you would need to switch from uap10.0.18362 to net6-windows.
I am novices to the field of Identity and Access management.
Till now I know, Sail point has provided the some direct connectors to integrate the known systems like LDAP, HR systems, OIM, Databases..
And sailpoint also provided the support for disconnected applications with the use of Custom connectors.
Here, My question is how to develop a custom connector..?
I do not have jar file provided by sailpoint which contain "AbstractConnector" class.
So that I can write my own class and develop..?
I also so not understand, what to do with that class?(if i have a jar)
How sailpoint will refer to that class..
Do we need to deploy that class to somewhere...
Here I am expecting the complete flow to develop and deploy the custom connector..
If anyone is working please help..
If you unzip your identityiq.war, you'll find a JAR file called WEB-INF/lib/connector-bundle.jar. This is the JAR where you'll find AbstractConnector. Once you've written your connector code, you will need to compile it and bundle it into a JAR file, which you will place into WEB-INF/lib.
Finally, you will need to update the ConnectorRegistry object (under Configuration on the debug screen) to reference the new class, which will make it available as an Application type. If it has custom connection parameters (as most do), you will also need an xhtml page that will be embedded into the Sailpoint UI to prompt the user configuring the Application.
If you have Compass access, they have a whitepaper called Custom Connectors that you will find helpful.
All that said, I encourage you to try to find a way to use an out-of-box connector if possible.
Most of the times it will be better if you use the DelimitedFile connector, you can import a CSV of identity data, and make it work within Sailpoint's workflow. You will be able to map fields, correlate accounts and create multi-valued group memberships rapidly. Of course, this means that Sailpoint will not be connected directly to the application, and you will have to develop a workflow to extract the identities and upload them. But at least, you can integrate without going the Custom Connector way.
I have two projects that both use the settings:
QSettings settings(
QSettings::SystemScope,
QCoreApplication::organizationName(),
QCoreApplication::applicationName());
I was under the impression that with SystemScome and the same application and organization names that these settings would be linked. But they aren't. What's the best approach for this?
Thanks!
EDIT:
It was on Linux, and I believe sudo needed to be used for SystemScope. UserScope did however work.
As it is thoroughly written in documentation - QSettings: Platform Specific Notes the path which QSettings use to store settings is uniquely determined by application and organization name parameters.
The First thing you could do is to check is settings are truly being written in location mentioned in link above for your system and what is different for those two applications. For example, there is a singular case that for windows their will be different for x86 and x64 applications.
Also if you try to use them simultaneously for both applications you should remember to use sync () function or create new QSettings instances when it's needed so the apps wouldn't conflict in operating on them.
If I want to call a web service or wcf method from an orchestration, I can do it by either adding a service reference to the project or adding a generated item. What is the advantage of either approach - is there a best practice?
Steef -Jan Wiggers answers a similar question here
TL;DR - Always use the Generated Items wizard.
My 10c - Although the .xsd files imported by Add Service is added as a schema and set to BtsCompile, there are some limitations such as:
Add Service Reference will add the client proxy, which isn't needed in a BizTalk project (and which might 'tempt' your devs to do silly things like using this proxy from a Custom assembly)
Service Reference makes a mess of importing complicated WSDL (e.g. with Generics or dependencies on other Schemas), See Considerations when consuming Web Services
Using the Add Generated Items wizard does extra work for you:
Adds in a Port Type for accessing the service, already preconfigured for the correct message types. Note however that it adds the Port type to a dummy .odx - i.e. don't delete the odx until you've moved the Port type elsewhere.
Allow you to create the Send Port bindings at the same time.
One thing I would recommend with the Wizard, is to create a folder for the WCF reference and always import all the artifacts into the folder (i.e. don't do the usual separation of Schemas from Ports and leave the dummy .odx there as well). This way, if you need to regenerate the items, just delete everything in the folder and start again (sadly, the wizard doesn't have a Update Service Reference equivalent.
Also note that if you do move the generated Schemas and Port Types into a separate assembly, that you will need to change the type modifier access to Public (it is internal by default)
I imported a Form object from a text file. When I try to compile it I get the following error message:
This message is for C/AL programmers:
The OLE control or Automation Server identified by 'Microsoft Common Dialog Control 6.0 (SP3)'.CommonDialog requires a design time license.
This license cannot be obtained.
Make sure that the OLE control or Automation server is installed correctly with an appropriate license"
I am developing in Dynamics NAV using a developer license. The OCX is registered correctly, gets listed in NAV's "Custom Controls" as pointing to "C:\Windows\SysWOW64\comdlg32.ocx".
Why am I not allowed to compile the object?
The license in question is, as you said, purely for using the CommonDialog component in design-time environments. This has nothing to do with your NAV license or your customers being able to run code that uses the component. The design-time license (which is nothing more than a key in your system registry; not an actual license file) used to get installed with e.g. Microsoft Visual Basic 6.0 or older versions of Microsoft Visual Studio.
If you have access to VB6.0 or VS2005, you can use VB6Controls.reg on the installation disk as described here: http://support.microsoft.com/default.aspx?scid=kb;en-us;318597.
As the message said, the components loads, try to get a license and don't get one. So you don't have one as it says or you don't have it in the path lookup the components looks at it.
There is one more trick you can do to fix this problem and avoid installing a lot of crap like VB6.0.
This message is related to certain automation type variable in the object you trying to compile.
You can copy this variable from any other compiled object in other database or any other compiled object in the same database. And then your imported object will magically compile. Just delete the variable from your imported object's variable list and copy it from compiled object with copy-paste.
I don't know what magic is that but it worked for me many times. I copied variable from the same object in restored backup of the database.
