Debugging reports (C# / netframework)
Note
This demo is available in your FlexCel installation at <FlexCel Install Folder>\samples\csharp\VS2022\netframework\20.Reports\52.Debugging Reports and also at https://github.com/tmssoftware/TMS-FlexCel.NET-demos/tree/master/csharp/VS2022/netframework/Modules/20.Reports/52.Debugging Reports
Overview
As you have seen in the previous demos, tags can get complex once you start nesting them one inside the other to get a result. This demo shows how to investigate expressions on your report, and deal with bugs in your expressions by looking at what is going on inside the hood. Make sure you read Debugging Reports in the Report designer's guide for more in depth information.
Concepts
- How to use the <#debug> tag in the config sheet to activate debug mode. Note that we could get the same effect by setting FlexCelReport.DebugExpressions and FlexCelReport.ErrorsInResultFile.

//
// 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("")]
[assembly: AssemblyDescription("")]
[assembly: AssemblyConfiguration("")]
[assembly: AssemblyCompany("")]
[assembly: AssemblyProduct("")]
[assembly: AssemblyCopyright("(c) 2002 - 2024 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("7.21.0.0")]
//
// 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.
