I have a variable for startdate as shown below.
Dim startDate as Datetime
startDate = Convert.ToDateTime(datepicker1.text).ToString("dd-MMM-yyyy")
In the immediate window if I try Convert.toDate(datepicker1.text).toString("dd-MMM-yyyy")it is showing date as 29-Sep-2009 but the value of startDate is 09/29/2009 I really don't understand why the value is not set in startDate variable as 29-Sep-2009
I want to do 2 things with date & time calculation : First : I have a LastSave (dateTime Format). I have two controls (NumericUpDown / Format Decimal), one for Hours, the other for Minutes.I want to start another save at a specific time this day at : Today's date + Hours + Minutes.What i've done isn't work, cause i can't convert to DateTime my setting

I am a bit confused when comparing StartDate and EndDate in my asp.net app.
EndDate: 10/1/2011
StartDate: 9/30/2011
The if statement below returns true, based on the date values above.
If strEndDate < strStartDate Then
I would think the If statement shoudl return false. The concept is supposed to be that if EndDate is earlier than StartDate, display an error message.
how to compare startdate and enddate? [code]Startdate cannot bigger then endstart to protect this condition.

i.e. End Date: 05/5/2011

Start Date = 29/04/2011
My OS is Vista Home Premium (64-bit) SP2. I've been working with VS 2010 Beta 2, wrote a few apps, and downloaded the Aug 2009 DirectX SDK. I have all of the source code for a game I wrote ten years ago (with VB5 using DirectSound and DirectInput from DX7) and I would like to get it working with the latest VB and DirectX (and use Direct2D also) but the first problem is that I can't even find how to "include" directx into a project. I was hoping to make a small example app to figure out what I need to do to update my code and what capabilities D2D has, but I can't even get out of the gate with DirectX.

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.
-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.
Say that i have the following code that parse about 20k records from the DB.
Code #1
vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While
And then another code which does the very same thing but it seems to be a little cleaner.
Code #2
vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While
This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?
I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.
[Code]...
The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.
