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

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.

View 6 RepliesI am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet
