When you open a project created using a version version 5.0 in version 6.0, whether the control created in the program will be upgraded.
Some controls will be automatically updated to the latest version, but there are several controls that cannot be. This is because some controls cannot be compatible backwards. If these are automatically updated, this will disrupt some code.

When you encounter the above error message, click the OK button to install an update version of Oleaut32.dll compatible with the installer. The system must be restarted after the file is updated. Only the machine can continue the installation process of the application. Run the setup.exe program in the application after the machine restarts.
If you have selected Cancel, the setup.exe program will terminate the execution. The application's installation process will not be completed before this system is installed with Oleout32.dll 2.20.0000 or its higher. To understand more information about the system file, see the following documentation in Microsoft Knowledge Base ... System Files Are Out of Date.
What kind of product is the Data Report Designer in Visual Basic 6.0?
Microsoft Visual Basic 6.0 Data Report Designer is a hierarchical report design program built in Visual Basic 6.0.

The Data Report Designer in Visual Basic 6.0 is mainly designed to require the following functions: I hope to quickly print the text-based single-oriented or hierarchical report, and you want to reuse the drag and drop function using VB6 Data Environment Designer. Created data objects. Seagate Crystal Reports not only allows developers to easily build relatively simple reports, but also allow developers to build more complex reports. Its advanced format and group features such as charts, multiple output forms allow developers to easily include rich reports and analysis information in the program. In Visual Basic IDE, developers can reach the above purposes by using RDC. Seagate Crystal Reports also provides developers with greater flexibility, which allows end users to create and modify their own reports without any changes to the application.
