Cute Editor defines the following image name filter by default:
^[a-zA-Z0-9\._-]+$
But you can modify it to meet your own requirements using the following methods:
1: Edit security policy file.
The security policy file (default.config, admin.config and guest.config) can be found in the /CuteEditor/Configuration/Security folder. In security policy file you can find the filenamePattern element. By default, it contains the following value:
<security name="filenamePattern">^[a-zA-Z0-9\._-]+$</security>
You can modify the filenamePattern element to meet your own requirements.
For example:
<security name="filenamePattern">^[a-zA-Z0-9\._-]+$</security>
2: Programmatically define the image name filter
C# Example:
Editor1.Setting["security:filenamePattern"]= "^[a-zA-Z0-9\._-]+$";
VB Example:
Editor1.Setting("security:filenamePattern")= "^[a-zA-Z0-9\._-]+$"
