Why to register a control
	In order to let applications use a component, it has to be registered. This simply means that you have to inform the OS telling to look at the component file, in the directory where it is placed. It is responsibility of the OS to recognize the control and its exported properties and methods in order to let other applications access them. Our installation process will automatically register all purchased controls. Back to Top

How about the royalty free policy of DAS software?
	The DAS(Dragonfly Automation Software) products are royalty free for use in any compiled binary or web applications. That means you may distribute your applications with any DAS software components used in your applications in no royalty fees. You may NOT distribute any license files, license run-time registry keys or license setup files, and you may NOT distribute any sample program and electronic or printed documentation. No run time fees. If you are writing an application that you intend to distribute to many end users, there is no additional fee associated with distribution of your application using Dragonfly Automation Software components. This is true in all cases unless your application's distribution necessitates the distribution of Dragonfly Automation Software licensing for our product(s).For details, please refer to Licence Policy. There are no run-time fees for use of our components on a web server. If You create a composite component, you are allowing your end users to develop with our controls. This would require a royalty agreement with us. Back to Top
Can all the controls share one license registry key?
	All controls just need one license to install in one computer with Single License version or in multiple computers with Site License Version. One Single License or one Site License are for whole controls. So the customers do not need to buy many registry key for different control components. Back to Top
How about Run-Time licenses of DAS software?
	Many customers inquire about the Run-Time License Distribution policy. In general, the applications(not a development tool to allow your customers to develop their own applications using these components)which needs DAS components do not need to pay runtime license fee for these DAS components, because they are royalty-free at runtime (as they have embeded our license keys in their binary codes like applications developed by VB or VC, they do not need to distribute our license keys to their customers, so all runtime license keys are hidden to their customers so that thir customers can not develop other applications by using DAS components.) But if you want distribute our runtime license keys explicitly(which implies that your customers know what these runtime license keys are) to your customers so that your customers can apply these runtime keys to dynamically create instances of our components, then you need to pay us the Runtime license fee. If you allow your end users to develop with our controls, then you are required to pay royalties. This is because you are able to now distribute our "components", competing with us using our own product. If you attempt to bypass the ActiveX licensing mechanisms and allow the end user to develop with our controls, then you are required to pay royalties. You are not allowed to distribute the License Setup files under our standard license agreement. These files would enable your end users to develop with our controls. There are only very rare circumstances where this is necessary, and they would require a royalty agreement with us. Back to Top

How do I distribute your ActiveX components?
	You only need to copy and register the dll files for those components that you program uses on the destination computer to successfully distribute our ActiveX components. You can follow one of the following methods to distribute our components. Our ActiveX components have no dependencies on any other operating system files. WARNING!: under our license agreement, you are not allowed to distribute the license setup files that are associated with our ActiveX components to your end user's computers. Also, there is generally no need to distribute the associated TLB files. Just distribute the dll files in the components folder. Manual Registration This method involves a manual installation of your compiled software and our ActiveX components. This is generally used in situations where you are only distributing your application to a few number of computers. Copy the component dll files that your program requires (Example: copy the "DAS_AX_Gauge.dll") to one folder (you can create one or any existing one) the target computer. Open up a command or DOS prompt and execute the following command in where you placed the dll files. You can also use the START/RUN command "REGSVR32 ...YourFolder\Control.dll" Installer Registration This method is the preferred option if you are planning on distributing your application to many computers or if you will be having your end users install your software on their own. Most installation programs such as InstallShield, WISE Installer, Microsoft SMS Installer, NullSoft's Install System (Freeware), etc. can automatically register ActiveX controls for you. Refer to the installation software manufacturer's manual and help files for instructions on automatically registering ActiveX controls on your target computers. DAS uses the InstallShield installer to initially register your development ActiveX controls on your computer. Many corporations already have licenses for Microsoft SMS Installer, so that is generally the installer of choice for internal software distributions. If you are on a budget, NullSoft's Installer is easy to use, lightweight, and free. Back to Top
