Custom previewing (C# / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\csharp\VS2022\netframework\25.Printing and Exporting\20.CustomPreview and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/csharp/VS2022/netframework/Modules/25.Printing and Exporting/20.CustomPreview
Overview
FlexCel comes with a full featured viewer that you can use to display a preview of Excel files in your application, and without having any printer installed.
Concepts
How to create a preview form that you can embed inside your application, including thumbnails, navigation, etc.
How to Export to PDF from a thread, allowing the user to cancel it.

//
// General Information about an assembly is controlled through the following
// set of attributes. Change these attribute values to modify the information
// associated with an assembly.
//
[assembly: AssemblyTitle("Custom Preview")]
[assembly: AssemblyDescription("A custom previewer of xls files using FlexCel engine.")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("TMS Software")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("(c) 2002 - 2025 TMS Software")]
[assembly: AssemblyTrademark("")]
[assembly: AssemblyCulture("")]
//
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the '*' as shown below:
[assembly: AssemblyVersion("7.25.0.0")]
//
// In order to sign your assembly you must specify a key to use. Refer to the
// Microsoft .NET Framework documentation for more information on assembly signing.
//
// Use the attributes below to control which key is used for signing.
//
// Notes:
// (*) If no key is specified, the assembly is not signed.
// (*) KeyName refers to a key that has been installed in the Crypto Service
// Provider (CSP) on your machine. KeyFile refers to a file which contains
// a key.
// (*) If the KeyFile and the KeyName values are both specified, the
// following processing occurs:
// (1) If the KeyName can be found in the CSP, that key is used.
// (2) If the KeyName does not exist and the KeyFile does exist, the key
// in the KeyFile is installed into the CSP and used.
// (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.
// When specifying the KeyFile, the location of the KeyFile should be
// relative to the project output directory which is
// %Project Directory%\obj\<configuration>. For example, if your KeyFile is
// located in the project directory, you would specify the AssemblyKeyFile
// attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]
// (*) Delay Signing is an advanced option - see the Microsoft .NET Framework
// documentation for more information on this.
