Getting Tips -Date/Contract Validitation?
Apr 6, 2011
Can you guys share some techniques and methods on how you validate dates, where and how to do and stuff like that.Like If you were to set a new employee's five month contract, and having him/her account terminated on contract ending.Let's say I built a Lan-Based Management Information System and a small application that will automatically routes/scan every dates in the database every 1 mili-second using a Timer Control in VB to identify which date has been reached to dismissal phase.

So I implemented my own form of Enum static classes so I can associate strings to enumeration values. One of the shared functions in each enum class, GetValue, is used to quickly look up the string value from an internal array via the offset. While all of the enum classes implement the same exact function, the data types of their parameters differ, specific to the enums in each class.
So I come to a point where I want to create a generic class that can use any of the enums by passing it as a generic type parameter. But I cannot find a way to constrain type T in such a way to be able to call each enum's GetValue function. This is where an interface would come in handy, but VB.NET forbids interfaces for shared methods.
I have a base class that I could constrain to, but the base class doesn't implement the GetValue method, and I can't define a generic version of it, because I need to rely on shared properties of each child class in order for GetValue to do its thing.[code]..

I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from.

Is it possible to add the tips to your code in the sub so the user know what part of the sub is for? Like if I create a sub like this:
Private Sub Stuff(ByVal Tip as String)
End Sub
When the yellow box comes up you might see something like:
Quote:
Private Sub Stuff(Byval Tip as string)
This is just some text you use in the sub, don't worry about it.

I started learning VB about one month ago and I try to make some programs to learn a bit. Right now I'm trying to make an application that will open a website, click on the url there, wait for a set amount of time, click on a button on that page then go back to the main page and restart with another url.

Instead of the tool tips popping up next to the cursor, it would be more convenient for me to have them appear in a label on the status bar.
I've tried to myself, but had no luck. I also had no luck googling it. I mean, I could go about it in a shameful "ghetto rig" way by applying mouse overs to all the items and having them change the text in the label on the bar, but that's a waste of time.

The program should request the person's occupation, the amount of the bill, and the percentage tip as input and pass this information to a Sub procedure to display the person and the tip. Title is gratuities, first line Person's occupation, amount of the bill:, Percentage tip: Compute Tip, and show the tip. Im not sure how to approach it properly.[code]

JUst started to program in VB again after a long downtime (5-6 years).During this time I have been programing in ADA , Java and have therefore forgotten the "VB-way of doing things". Anyway..I'm triyng to build a web-aplication that looks like a normal questionform. [code]When the user hits "Submit" I want to add this information to a Excel-sheet(that exist in the same map as the web-page).Also I want to to program to check if that "Type" of event is already book for that date and time.I can easily do some of this in a "normal " application but is there anything special I have to think about when it's a web-app?Im also wondering how its works when you want to copy info from my application to a excel-book. How do I do that ?

I have a project with Control arrays that include over 200 controls.
I could use Tipster to define a Tool Tip or I could assign a Handler for the MouseHover event & use the handler to provide a help remark.
Would the Tipster approach result in the use of more memory/code than the MouseHover approach to this job?

working with dates has always been a tricky part so let me show you how I handle dates in my application and please could you show how do you handle dates and also feel free to criticise. Normally I would create out a system to be able to save and then load a date note I am using a varchar(50) on my SQL Server db rather than datetime but I understand this is wrong, that's why I am looking for a decent way to work the dates out. My system has worked for me fine so far but if I would have to sort the dates ascending or descending I think I would get into trouble because it is saved as text.

I basically have an abstract class that deals heavily with Generics. I need to call a Shared method on the Generic class T. I need to make sure the Shared method is implemented. I could use reflection to check for the implementation and call the method if it exists or throw an exception otherwise. However, since the derived class is not "aware" that it needs to implement this method, I feel that the exception will get thrown more often than not

I'm currently debugging a form that sets a flag when the mouse button is pressed, then clears the flag when the mouse button is released. As long as the mouse button is pressed, the user can move the mouse around and a few things happen depending on where they move. One of the things that happens is that a timer starts, or stops, and a few things change color depending on the mouse position. The timer starts when it should, then stops when it should, but once stopped, it is not re-starting when it should. I can verify that MouseMove events are getting through, because coloring changes as I move the mouse, as it should. This would be a simple thing to debug...except that it requires the darn mouse button to be down, and it uses the mouse move event. Anybody who has put a breakpoint in a mouse move event handler knows the issue: There are THOUSANDS of them. Worse yet, since the mouse button is necessary for switching to the IDE, as well as setting a breakpoint (technically, a keyboard shortcut could do this if I could shift focus), I can't wait for the problem to happen, then switch to the IDE and set a breakpoint to see what is happening then.Does anybody have any tips or techniques for debugging in mouse move events when the mouse button is down and has to stay that way? As it is, I'm going to have to write some funky code into the method just so that I have a place to get a breakpoint when I need it without breaking on every one of the mouse move events.

how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

I have a date time as a string, eg. "2010-08-02", I'm trying to convert it to UTC with the following code snippet..DateTime.ParseExact("2010-08-02Z", "yyyy-MM-ddZ", CultureInfo.InvariantCulture)When I print to the console, I get the following: 8/1/2010 5:00:00 PM.Is there a reason why the date shows up as the date before the date I'm trying to parse? I could just add a day to this to advance to the original day.

I'm fairly new to ASP.NET & VB.I've been asked to take an existing textbox that is automatically filled with the current date and allow the user to either add a "+" or "-" and a number or a spcific number and convert that into a date.I underdstand the basic concept on how to do this, but I'm running into some problems using the proper commands in order for this to work.The Textbox is called txtDate.What I've tried to do is this:
If txtDate = '+' Or '-' Then
DateAdd("d", txtDate, today)
End If
Here is what the whole thing looks like:

I 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

I have two tables: a schedule table that contains information about how an employee is scheduled and a numbers table in which each number corresponds to a date.
[Code]...
I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
