Hi Neil,
Thank you for your interest in Essential HTMLUI.
Please check the following settings in your project.
Check the default namespace set in the project. Right click with your mouse on the project inside VS.NET''s Solution Explorer and select the Properties menu item from the popup menu.
This will display the Property pages for the project. Note the Default Namespace under the general section.
Click
here for a sample.
In the above sample, the default namespace is Syncfusion.Windows.Forms.HTMLUI.Samples. To load a resource that is embedded in this assembly, you would needs to specify this namespace + . + name of the resource.
Also make sure that the HTML file is marked with the BuildAction = Embedded Resource (Right click the file inside VS.NET and select properties)
Please let us know if you have any further questions.
Regards,
Davis
