How to ignore error due to Iprop dLL?

While working with XlsIO in 64-bit mode, an "Unable to load DLL iprop.dll" error is raised.

Essential XlsIO requires the redistributable iprop.dll to be installed on 64-bit Windows machines. This can be resolved in two ways:

• Place the DLL in the location C:\Windows\SysWOW64

Here is the link to find this DLL:

• Use our new compound file storage

This issue with the Windows API dependency can be ignored by using our new compound file [.xls] storage, which is implemented with fully managed code. This can be enabled by setting UseNativeStorage of IApplication to false.

Here is the code snippet:

C#

ExcelEngine excelEngine = new ExcelEngine();
IApplication application = excelEngine.Excel;
application.UseNativeStorage = false;

VB

Dim excelEngine As New ExcelEngine()
Dim application As IApplication = excelEngine.Excel
application.UseNativeStorage = False

Take a moment to peruse the documentation, where you can find basic worksheet data manipulation options along with features like Conditional Formatting, worksheet calculations through formulas, adding charts in worksheets or workbooks, organizing and analyzing data through tables and pivot tables, appending multiple records to a worksheet using template markers, and most importantly, PDF and image conversions, etc., with code examples.
