XLSReadWriteII4 is a great component, I want to use it on the project of our company, replace Excel and improve system performance, but is pity that it dose not support custom properties, include workbook's and worksheet's custom properties, it is very important for our project.
Is possible to support custom properties in nearly future? I will be determined to continue use Excel or use XLSReadWriteII4 replaced.
regards.
FYI: dsofile component of Microsoft can support workbook's custom properties, but dose not support worksheet's.
