mates,
how to convert date to integer in vb.net. I searched already in google
and test it. Convert.Int32 is not what i want.
When i code it in
VB6/VBA:
Dim m_lDate As Long
m_lDate = Date
m_lDate = DateAdd("m", -1, m_lDate)
This will work.
But it VB.NET:
Dim mDate As Integer
m_lDate = Date
mDate = DateAdd("m", 1, mDate)
Got an error:
Value of type 'Date' cannot be converted to 'Integer'
How to do that in VB.NET?
Thanks in advance

What do you want the int to be tho ? Would the property that returns a value in Ticks do what you need ?

I need it to my function that will add date, month, and year when i press
+/- button.
Here's what i did in vba.
Function ScrollDate(FNAME As String, CTname As Control, vskip)
Dim CTLN As Date
CTLN = CTname
CTLN = CTLN + vskip
CTname = CTLN
DoCmd.RepaintObject A_FORM, FNAME
End Function
So everytime i will click +/- button, i will call ScrollDate
Perfectly working in vba.
But in vb.net. I don't know what to do?

YOu mean, add two dates together ? How does this relate to having the date in a form as a single int ? What I don't get it, what format do you want, specifically, or don't you care, so long as it represents a date as an int ?

yes, i don't care the format, as long as i get the int value from date value.
Example in vb6/vba:
myDate as Long
myDate = Date (2009/03/23)
so therefore myDate = 39896 (long)-->i need this in vb.net

OK, so ANY int value will do ? So the Ticks property I suggested you use, in my first reply, will work just fine ? DateTime.Now.Ticks

a) By searching google and following the thousands of examples.

It took you 7 minutes here and still no direct answer. While, googling would have taken less than a minute.

I read the second field, which is the time field into this structure TickData(i).dTime.Str But I can't figure out how to put the hour into TickData(i).dTime.H and the minute into TickData(i).dTime.M and the seconds into TickData(i).dTime.S.
My structure's are as follow.
Structure TickTime
Dim H As Single
Dim M As Single
Dim S As Single
Dim Str As String
End Structure
Structure TickD
Dim CPrice As Double
Dim dTime As TickTime
Dim Vol As Double
End Structure
Could someone Please help!
Thank You
Gary

The key is the Split method.
Dim timeParts() as string
timeparts = TickData(i).dTime.Str.Split(":")
TickData(i).dTime.H = Ctype(timeParts(0), Single)
TickData(i).dTime.M = Ctype(timeParts(1), Single)
TickData(i).dTime.S = Ctype(timeParts(2), Single)
Unless there's a reason for using Single in the Structure for the time elements, you might want to save some bytes, and eliminate any possible rounding issues by using Integer or even Short.

I tried it but this is the error I got.
System.NullReferenceException was unhandled
Message="Object reference not set to an instance of an object."
Source="TickChart"
StackTrace:
/////////////////////////////////////////////////////////////////////////////
This is how I did the loop!
Dim timeParts() As String
For i = 1 To UBound(TickData)
timeParts = TickData(i).dTime.Str.Split(":")
TickData(i).dTime.H = CType(timeParts(0), Single)
TickData(i).dTime.M = CType(timeParts(1), Single)
TickData(i).dTime.S = CType(timeParts(2), Single)
Next

Looks like a confusion of variable names. The object "TickChart" has apparently not been instantiated. I don't see "TickChart" anywhere in this discussion except in the unhandled exception. I may have caused the problem by using "TickData" in my code. Should that be "TickTime" instead?

Here is how I started
Structure TickTime
Dim H As Single
Dim M As Single
Dim S As Single
Dim Str As String
End Structure
Structure TickD
Dim CPrice As Double
Dim dTime As TickTime
Dim Vol As Double
End Structure
Public TickData() As TickD 'price data array
Then I loaded the data into TickData in a LoadData sub
Sub LoadData()
ReDim TickData(50)
end sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim i As Integer
Dim timeParts() As String
For i = 1 To UBound(TickData)
timeParts = TickData(i).dTime.Str.Split(":")
TickData(i).dTime.H = CType(timeParts(0), Single)
TickData(i).dTime.M = CType(timeParts(1), Single)
TickData(i).dTime.S = CType(timeParts(2), Single)
Next
end sub
But I still get that same error from the above Bold Text!

1. Looks like there is a possible scope issue. Try making both of the Structures and all of their components Public. E.g.:
Public Structure TickTime
Public H As Single
Public M As Single
Public S As Single
Public Str As String
End Structure
2. All arrays in .NET are zero based. Your For...Next loop starts at 1. You might also use the .NET version for getting array bounds. With the below changes the loop will look at all 51 of the array elements.
For i = 0 To TickData.GetUpperbound(0)
3. I'm assuming there is more code in the LoadData sub other than the Redim statement. Are all 51 elements (including TickData(0)) of the TickData array being populated? If not, that could also cause the error. If there is less than 51 data records being read into the array, the size of the TickData array cannot be larger than the number of data records minus 1.

Thanks alot George, I was trying to read more elements than I had, which was causing the error. Now I will be using TickData.GetUpperbound(0).
Thanks again

Look into the DateTime.ParseExact function. You may also need to look into the format specifiers

Thanks you I will do that.
