When I try to create a sharepoint web under my test account, I have come across this error:

parsing "^[a-zA-Z0-9_\.\-\_]*$" - Unrecognized escape sequence \_.

What has happened?

unrecognized escape sequence typically refers to c# code that blows up when you forget a \ before " or \. IE...

string test = "string\\string"; would be valid whereas...

string test = "string\string"; would not and throw an unrecognized escape sequence.

Have you edited the code behind or added some modules of your own?

But I am trying to install a new package- I have my existing software manually installed on the host, however I am not even to the place where I am choosing which website the package to be installed on, shouldnt that not be related yet? I don't know how I could install the application package and my own source together, I was expecting them to go into two different virtual folders/websites.

Hi Goodwill,

Can you give me your URL and the package that you are trying to install and I will take a look?

Cheers,

Dear Mark,

I realize the problem now, its my email account name- it contains '.' in the email.

I would send a PM to you on the details.

I am having the same problem. It gives me this error whenever I try to create any of the .Net applications. Joomla and phpBB don't have this problem.

Also, I see you guys are running version 1.6.0 of DNP, but according to their site, 1.5.3 is the latest release. ?????

Sorry for the double post....and I'm not sure why it lists the error twice in each post.

Hi itechs,

We are using 1.53 but for some reason the web interface (which is Beta 1.0) updates the version to 1.6.

Cheers,

Mark-

Thanks for fixing it. Was the problem trying the \_ in the RegEx like I mentioned in my ticket?

Hi itechs,

No problem. The problem came about as we had changed the naming convention for databases to allow ' - '. For some reason this caused the validation to fail. Anyway DNN 4.35 and 3.35 have also been added to the application installer.

Cheers,

Mark
