You can either edit the the project file in text editor or get a working version from version control. Un-registering and registering again worked for me too.
Please note that you need to register this component using this syntax:. When you say you have used "REGSVR32 on the file to no avail" do you mean that you get a file name succeeded message, or an error message?
If registering the file succeeds CMB is likely right about the ocx being unlicensed. Licensing aside, there are a couple of other trip points with vb6. If so, the 'officially' system registered version may conflict with the specific ocx you're using. In other words, both of them might have the same proper name or classid but the one you're attempting to use may not implement all the functionality described in the system registered one i. This arises when the author desires to maintain binary compatibility while enhancing the functionality of a control.
As long as the public interfaces remain compatible, vb will not recalculate the classid. You can fix this by forcibly unregistering the specific control actually unregister all instances of the control. Be certain that no running instance of VB6 exists when you do this or the results might not work. Check your task list. The control may be reliant on another DLL or OCX that may be missing or not registered and this could manifest itself as VB reporting that the control you're trying to use is missing.
However, I'm not sure how you would identify the dependencies. As far as I know, dependency walker identifies static dependencies; I'm not sure if it can identify COM dependencies. If an existing project suddenly starts to generate an error saying "You must have a license to use this ActiveX control", it could be because the OCX file has been registered again on the development machine at a new location.
This can happen if an installer is run to deploy an application that uses the control. Most versions of Visual Studio can produce 32 bit or 64 bit applications.
To check which version of the csXImage control is actually being used by the application, display the about box from your code.
This will indicate whether it is the x86 or x64 version. In many applications it will make little difference which version is used. However, in a Twain application that uses a scanner, it will affect which devices are available. A 32 bit application can only use a 32 bit scanner driver and a 64 bit application can only use a 64 bit scanner driver. Similarly, if there are any other dependencies in the application, including calls to a database driver, there must be no mixing between 32 and 64 bit.
However, if you intend to distribute the applications to others, and if you put the OCX in System32 folder in others' computers, you have to make sure that you are choosing a unique file name, to insure that no one else in the world came up with the same OCX name and therefore would overwrite your OCX because it has the same file name and it's installed to the same folder System OCX, and someone else in the world thought about using the same file name, your file is overwritten, and your program would show errors at startup Or the other developer's app, depending on which application was installed last.
This insures that the file is not overwritten. I will keep that in mind. Copying files from different locations to different locations.
Problem with OCX locations on two different computers. Connection cursor location vs. Recordset cursor location. Dependency Files for comctl
