View 4 RepliesI'm trying to validate an IP address in dot decimal format e.g. 127.55.21.1

This though returns numbers like "500" or "9" as valid. Why does it do this? Do I have to set the IP address version, if so how would I do this?
I would like to check the format of a string value (contained in a variable) before using it in further code.
- It must be 8 characters in length (no more, no less)
- It must be in the following format: 2 digits + 1 letter + 5 digits
I imagine the VB.NET code would be something along the lines of:If CStr(strMediaNum) (...not in the form [2 digits + 1 letter + 5 digits]...) Or (...datalength not equal to eight characters...) Then Exit Sub EndIf
How to validate the Date format "MM-yyyy" irrespective of the culture datetimeformat
View 2 RepliesI need to validate user input in some fields, where these are defining how to show time in some views.
Requirements: Time format must be expressed in Microsoft .NET way (check this MSDN Library article if you want to learn more about framework's date and time formatting: [URL]. Keep in mind I'm looking to validate the format instead of an actual time string.
For example, user may input:
HH:mm
hh:mm
ss
hh:ss
mm:ss
... and so on.
In fact, it should validate from the shortest to longest time format available. Another point is I need to do it in client-side using JavaScript. In other words, any given regular expression by you should work in browsers JavaScript regular expressions' engine. I can't use ASP.NET validation engine, or any other. Because of project's requirements, I need to avoid that.
I wonder how I can validate that the GPS coordinates are inserted in the right format.

I have a lot of controls on my asp.net web form that require validation. Rather than list each control in the code behind page that requires validating I would like to add the css class "required" to the necessary controls and then on submit the code behind will validate each control with this class. I'm fairly new to .net so here is some Pseudo code:
Public Sub ValidateAllControls(ByVal a As Object)
For Each c As Control In a.Controls
If c.Controls.Count > 0 And c.Controls.class = "required" Then

I need to accum some data based on whether or not an SSN number appears in the data. I have it in a string, what I need to do is search for a numeric pattern within the string such as:I looked into regex a bit, but I don't have much time to read deep into it (my company needs the program this week) and it seems too complex to grasp in such a short time. What I've came across so far is:
If (rec.address1 Like "###-##-####")
but I don't know if this will filter it out of the string (it can appear with an address attached to it).

View 3 RepliesI'm writing a little web service which generates SO/SF/SU/MSO user flair in the form of an image with various "themes". I find this preferable to using the HTML/JS solutions offered by SO as it's more flexible and also works better in forum signatures.
I'm retrieving the data using the apparently unofficial API (More info here). I can have the data in HTML or JSON. I assumed the JSON would be easier to parse.
Unfortunately, I'm not great at regexes. and the best I can come up with is some very hacky sub-stringing. I believe a regex should be the most elegant solution
regex that matches ID, GravatarURL, ProfileURL, DisplayName, Reputation and Badge Counts (Bronze/Silver/Gold).
FWIW This is to be used in a VB.Net project (in case that affects the syntax at all)

In case any of you are interested, some screenshots of the flair as a work in progress are available here: Me, Jeff Atwood, Joel Spolsky
I am working on a simple window application (VS2010,VB.NET). It's an HR management App - Employees records.I need simply insert/edit Employee Info, reports in Excel (with out crystal reports) & Show in Grid.So I am thinking of using Telerik RAD WinForms (2011) only because it looks cool. But I also know that Telerik could be a real pain when you need more flexibility.Although my application is quite basic still I want to determine whether I should go with Telerik or just use standard Windows Forms functionality? How can I generate custom report in specific format.Also It would be nice if some one point me to some sample application or VB.NET windows Tutorials?
