When you create reports to be used on different computers and by different users, please read these important notes.
Vitalii Levchenko Software develops several applications, which can work with Reportizer reports: Reportizer, Reportizer Viewer, and Database Tour Pro.
All the applications use the same report engine and can be used to preview and print the same reports, if the version of the application, where you make the reports, is compatible with version of the application, which will use these reports. The best way to ensure the compatibility of your reports is to have the latest versions of the applications installed, but if it is not always possible in your case, please read the notes below.
Static reports
In most cases, you should not worry about compatibility of such type of reports, because it is done by the applications. But in the case of errors when opening such reports, you should install the latest version of the application.
Dynamic reports
In the case of incompatible versions, some of the report objects' properties, which are implemented in the latest versions, may be lost in the older applications, or (in the worst case) the dynamic reports will not be loaded at all.
You can verify the compatibility of reports by checking version of report engine: report engine version, supported by the application, is shown in About section; report engine version, by which the dynamic report was generated, is shown in Engine Version property of Report object. So, if your end user's application supports the same version of report engine as your report or above, the compatibility is guaranteed.
In the case when you cannot control the versions of the applications on end users' computers, please stick to this simple rule:
Converting reports automatically or semi-automatically
Reportizer of a later version, when loading a report created in the earlier version, tries to convert it to current version automatically. It also sometimes issues warnings telling you what you to change in order to get the old report working. If the old report still remains unusable, registered customers may ask for support.
