Regex 4 Digits A Hyphen And 4 Digits?
Jul 2, 2010I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

Cutting Off Digits And Rounding Up/down?
Jul 22, 2010I need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.
GUID Creation In 30 Digits?
Oct 1, 2010Now i am doing a vb.net desktop application, In which i have to construct GUID. Eventhough having a built-in function in our VB.NET like "System.Guid.NewGuid.ToString()" to get GUID, I need to create the GUID in 30 digits in the below mentioned criteria through vb.net.
Application constructs the GUID (30 digits) using the information from the 5 different sources. The different sources are Current system time, millisecond of the system time, Process ID for the application, system physical memory status and finally the group object identifier number.
8 digits
4 digits 8 digits
8 digits 2 digits
[Code]....
I am not sure how to get the above values to construct the GUID?
