Error compiling demo on local v17.1.0.47

[Matanya Cohen]

I have Community lic.

I download install Essential WPF. I open the Panel and try: 'Run Local Demos'

For some demos, I got (VS 2017):

Severity Code Description Project File Line Suppression State

Error CS0103 The name 'DemoCommon' does not exist in the current context PropertyGridConfiguration_2017 C:\Users\Public\Documents\Syncfusion\WPF\17.1.0.47\Tools.WPF\Samples\PropertyGrid\Getting Started\CS\App.xaml.cs 25 Active

For another demo I got:

Severity Code Description Project File Line Suppression State

Error CS0234 The type or namespace name 'DemoCommon' does not exist in the namespace 'Syncfusion.Licensing' (are you missing an assembly reference?) ExpenseAnalysisDemo_2012 C:\Users\Public\Documents\Syncfusion\WPF\17.1.0.47\Showcase\ExpenseAnalysisDemo\CS\App.xaml.cs 24 Active

Hi Matanya, 

  

Thank you for contacting the Syncfusion support. 

  

Based on the provided information, we understood that the when running the some of the dashboard sample, you are facing the errors “The name 'DemoCommon' does not exist”. So, can you please paste the following code in the App.Xaml.CS file in the sample. 

  

    public static class DemoCommon 

    { 

        /// <summary> 

        /// Helper method to find a syncfusion license key from the Common folder 

        /// </summary> 

        /// <param name="fileName">File name of the syncfusion license key</param> 

        /// <returns></returns> 

        public static string FindLicenseKey() { int levelsToCheck = 12; string filePath =@"Common\SyncfusionLicense.txt"; string rootPath = System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().CodeBase.Replace(@"","")); for (int n = 0; n < levelsToCheck; n++) { string fileDataPath = System.IO.Path.Combine(rootPath, filePath); if (System.IO.File.Exists(fileDataPath))return File.ReadAllText(fileDataPath, Encoding.UTF8); DirectoryInfo rootDirectory = Directory.GetParent(rootPath); if (rootDirectory == null) break; rootPath = rootDirectory.FullName; } return string.Empty; } 

    } 

  

Example – 

 

namespace PropertyGridConfigurationDemo 

{ 

    /// <summary> 

    /// Interaction logic for App.xaml 

    /// </summary> 

    public partial class App : Application 

    { 

        public App() 

        { 

            SyncfusionLicenseProvider.RegisterLicense(DemoCommon.FindLicenseKey()); 

        } 

    } 

  

    public static class DemoCommon 

    { 

        /// <summary> 

        /// Helper method to find a syncfusion license key from the Common folder 

        /// </summary> 

        /// <param name="fileName">File name of the syncfusion license key</param> 

        /// <returns></returns> 

        public static string FindLicenseKey() { int levelsToCheck = 12; string filePath =@"Common\SyncfusionLicense.txt"; string rootPath = System.IO.Path.GetDirectoryName(Assembly.GetEntryAssembly().CodeBase.Replace(@"","")); for (int n = 0; n < levelsToCheck; n++) { string fileDataPath = System.IO.Path.Combine(rootPath, filePath); if (System.IO.File.Exists(fileDataPath))return File.ReadAllText(fileDataPath, Encoding.UTF8); DirectoryInfo rootDirectory = Directory.GetParent(rootPath); if (rootDirectory == null) break; rootPath = rootDirectory.FullName; } return string.Empty; } 

    } 

} 

  

Please let us know if by placing the code resolves the issue on your side. If not, please specify about the currently installed Syncfusion Essential Build details (Build Platforms and their versions) in your machine.

Seem somthing wrong in follow code:

Assembly.GetEntryAssembly().CodeBase.Replace(@"","")

Exception thrown: 'System.ArgumentException' in mscorlib.dll

An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll

String cannot be of zero length.

System.ArgumentException: 'String cannot be of zero length.

Parameter name: oldValue'

Ok, I try put the lic key directly:

Syncfusion.Licensing.SyncfusionLicenseProvider.RegisterLicense("...")

Instead add "FindLicenseKey"

But still need do it for every Demo project. dont it?
