I need to check if a variable is inside of a range.
E.g. I'll like to check if variable "input" of type Int32 with the value 5 is in the range from 0 to 15.
I've tried with
if (Regex.IsMatch(input.ToString(), "([0-9]|1[0-5])"))
Console.WriteLine("In the Range");
It doesn't work :-(
Can somebody help,

In VS 2008 there is a very useful feature of background HTML validation - it checks if CSS class name is valid i.e. it exists in one of the linked css files. But VS 2010 Express does not do that any more. And the relevant setting in Options->Text Editor->HTML->Validation->in CSS is not there. Ok, maybe they made it paid for option? VS 2010 Professional? Not there. Or maybe VS 2010 Ultimate? Not a trace.
1. am I blind?
2. they decided it is too convenient to use and removed it?
3. they will "introduce" it in SP1?
What is going on? That one thing made me move back to VS 2008 web developer.
I am validating user from Login.xlsx file. It was working fine by validating email and password from that file. For testing i got new file same contents of file but added some more user names.
So after that when i validating the user i am getting the following error "Data type mismatch in criteria expression".
But when i replaced the new to old one it is working fine. The contens of both files are the same. So why this kind of error happened.
I am using Validation application block in my project and want to set validation message from resource file, but not able to do that. I tried giving the path of resource file in messageTemplateResourceType and name of resource in messageTemplateResourceName. But it did not help as I only receive the message if I have set something in messageTemplate even after setting the resource file.
Here is my code:
<validator lowerBound="1" lowerBoundType="Inclusive" upperBound="250" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="PerilTypeAndDetailsSection.VMEnterWhere" messageTemplateResourceType="Asurion.jCare.Common.Resources.UIResources.PerilTypeAndDetailsSection, Asurion.jCare.Common.Resources, Version=220.127.116.11, Culture=neutral, PublicKeyToken=null" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.Enterpris
I need to validate an XML through XSD. I am using XMLReader (with XmlReaderSettings and
Validation_EventHandler to do it). Depend on users preference, I would like to change the output message generated by Validation_EventHandler in french or english.
Any idea on how to perform this?
I'm getting the following error:
[ArgumentOutOfRangeException: Value to add was out of range.
Parameter name: value]
System.DateTime.Add(Double value, Int32 scale) +7657639
System.DateTime.AddDays(Double value) +19
The line from which this error originates has the following code:
expires = Now.AddDays(30)
It occurs irregularly and irreproducably. The server date/time is correct and set to GMT. I've heard that it could be some curiosity to do with timezones, but that is speculative.
It seems that we're some time from the year 10,000 yet, so I can't understand why adding thirty days to the current time could cause this! Any ideas? Culture settings perhaps?
