When debugging apps that use Cute Editor we all receive the following error when pages are first loaded:

"string reference not set to an instance of a string"

 

You do catch the exception but it would be better if it did not occur at all ... this is an annoyance that would be very easy for your developers to fix.

 

This is what I can gather according to the stack trace, assembly etc., this is the best I can do without access to the source code:

 

Inside the Function a(Regex.Match) which is in the file LoadHandler.c (or LoadHandler.vb) you have a line like the following:

 

try

  {

  CultureInfo culture = new CultureInfo(str);

  }

catch (char* s)

  {}

 

 It would be a lot easier to find these errors if we had access to the source code ;o)

Here is the source code of this part:

 

Can you show me how to reproduce this error?

 

As far as replicating the problem it will probably be something to do with our server setup but the fix is easy ... the problem is caused because the culture string is empty or not defined.

 

To fix it please change:

ci=new System.Globalization.CultureInfo(culture);

 

To:

if(!string.IsNullOrEmpty(culture))
  {
  ci=new System.Globalization.CultureInfo(culture);
  }

 

This would make it a little more robust as it would avoid attempts to set the culture to an empty string. It would also be nice to get to the root cause as your method of getting the culture string should not produce an empty string.

 

We do use the following line at the beginning of each generated page in our web app:

System.Threading.Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.CreateSpecificCulture("en-US")

Maybe that has something to do with it.

 

If you need any information about my setup then please let me know, you can reach via email using michael.ratcliffe@comartis.com
