I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.I save the date in the registry like this:
Code:
Application.UserAppDataRegistry.SetValue("Date", [Date])
I then made a sub to calculate the differences:

Im a beginner at visual basic. I did some codes refering to a form in which I need to calculate the differences between my my date of birth to another date. I did a statement which gives me the difference between those in the format of years, but I need to know how I can put the months and days example if my birthdate is 11/26/1991 and I want to calculte how many years, month and days has transcurred until today it would be like 20 years 3 months and 11 days.

I know about DateDiff and TimeSpan. I am doing a project. I save a date in the registry. Now, I have to test this date against today's date and calculate the differences in minutes, hours, days, months, weeks and years.
I save the date in the registry like this:
Application.UserAppDataRegistry.SetValue("Date", [Date])
I then made a sub to calculate the differences:
Private Sub Calculate()
Try
Dim DateGen As Date
DateGen = CType([Date], Date)
Select Case TimePeriod
[Code] .....
As you can see, based on the difference between these dates ( today's date and the registry date ), a sub gets called and the program continues. Unfortunately, the minutes and hours never calls the RandomAlpha sub. How can I calculate the difference in minutes, hours etc.????

View 20 RepliesWhat are the differences between 32 and 64-bit .NET (4) applications?Often 32-bit applications have problems running on 64-bit machines and conversely. I know I can declare an integer as int32 and int64 (certainly int64 on 32-bit systems make problems). Are there other differences between programming an 32 OR 64-bit or a both 32 AND 64-bit compatible application?

View 1 RepliesWe have legacy character codes that we want to store as numbers in a new system. To increase readibility and general understanding in the code for devs making the migration, I want to do Enums like this..
[Code]...
With this setup, the code will be readable (imagine If Record.Status = Status.Open), and yet the values will be stored in the database as small numbers so it will be efficient. However... I am a VB.NET guy, but everybody wants to code in C#, so I need this sort of structure in C#.After Googling, I discovered the the general .NET equivalent of AscW is Convert.ToInt32("C"). When I try to use that statement in an enum, I get the compiler error "Constant Expression Required".
in order for me to get help on me and my programming partners vb6 rpg, I have to upgrade the project to the vb.net platform, and I am worried that the IDE interface that is used to program the vb side of the rpg is different, so I am wanting to ask any of you if there are any significant changes to the IDE or if it is relatively the same as it was in vb6... I am also hoping that someone here can also help me to see what is wrong with my load/save function... I now thought of something to try to see if that is the issue or not, but the code is still vb6 code, the only difference will be that the program will be upgraded to the .net platform, so if that changes anything in the code, then I am not aware of this as of yet, because I am still downloading the visual studios 2010 express iso right now... so I do not know for sure yet what will be changed.

View 1 RepliesToday I was playing around with Entity Framework and I've read that the generated IL for C# was different than VB.NET for the following code:
[code]...
As it seems the VB.NET version of this code will contact the database every time the code is executed while the C# version will retrieve the entities from the cache when the code is executed multiple times.Why would they make both languages behave in such a different manner?It was my misconception that both languages just differed in syntax and had almost exactly the same generated IL.Are there any more examples where both languages generated such different IL?

View 5 Repliesi'm using Enumerable.Except to check if a DataTable in memory is in sync with the table in database.
The background is: this DataTable and other frequently used tables are stored in the Cache of a WebApplication. But meanwhile i'm convinced that this is not a good approach because it's a source for nasty errors that are difficult to reproduce/debug.
Therefore i've created a function that checks if database and memory are in sync, otherwise an error-log will be created. This works perfectly. If there is a row in memory that is not in database, this row will be shown below "Difference in database", the same applies in reverse. But if rows exist in both datasources(the PK idRMA) and some values differ, the log will contain this row in two versions(below "Difference in database" and "Difference in database"). It is not easy to see the differences on the first sight.
Q: Is it possible to select only the properties that caused Except to think that first sequence is not in second?
This is the the complete function(the first lines are relevant):
Public Shared Sub CheckRmaMemoryInSyncWithDB()
Dim inSyncText As String
Dim color As Drawing.Color
