I have a UDT I created in SQL Server Express 2005 that is called time. I did not create an assembly so the date is always 1/1/1900.
I need to know how to get the time only from the data row.
How do I do that?
Here is a line of code in VB.NET. ts_from is the field in the database that hold the datetime value.
startTime = Convert.ToDateTime(row("ts_from"))

Why have you created a UDT? You can just use the datetime data type.

Hello
Thought I turn off option Type inference , I still has problem
Shared Sub Abc(Of T)(ByVal def As T)
End Sub
Shared Sub Abc(ByVal def As Object)
End Sub
Shared Sub New()
Abc("a string") '---> this line always calls Abc(Of String)(ByVal def As String)
'I really don't want to change existing code to Abc(CObj(""))
End Sub
|
|
|
|
|
You don't have a choice. Think of it this way... The compiler is going to automatically generate code specific to each type that uses this method. If you leave this setup the way it is, the method defined as ByVal def As Object will only be called when you pass something boxed in an Object type. Every other type will go to the generic version of the method.

hi,
This is what caused my problem.
i un installed a program that was using crystal reports.
the uninstallation removed all components for crystal in the program files/common files directory.
this is why i was getting the error.
Solution....well kinda solution...
i re-installed that software which put back all the modules and now it works fine.
i dont know why the uninstallation removed the components, but it did,
i will have to live to the software installed even though i am not using it... i dont mind!
hope this helps!!!

I have a line of code that I am not sure why I am getting the blue underline when I have option strict on.
The error I get is the following:
Option Strict on dissalows implicit conversion from date to string.
I know that I can use the code Convert.ToDataType() to convert variables and/or objects.
Here is the line of code I am having troubles with.
startTime += startTime.Add(timeInterval)
The startTime in previous lines of code is converted from a dataRow object to dateTime. The timeInterval variable is a timeInterval dataType.
Does anyone know what I am getting the conversion error? Does the Add function convert startTime to a String?

Shouldn't this be
startTime = startTime.Add(timeInterval)
Assuming that you want to add startTime and timeInterval and assign the result to startTime.

That is the same as:
startTime = startTime + startTime.Add(timeInterval)
There is no operator overload for adding two DateTime values. Then only implicit convertion that allows adding, is turning both values to strings, so the compiler assumes that you mean:
startTime = startTime.ToString() + startTime.Add(timeInterval).ToString()
However, the result is a string, and can not be implicitly converted to a DateTime value, that is why you get that error message.
Despite everything, the person most likely to be fooling you next is yourself.

Can anyone lend me a hand on properly coding the below IF, Then, Else statements to do a few things:
+ If my ExemptStatus = "Exempt", the text box txtCTOused1.Text should be disabled,
+ If my ExemptStatus = "Exempt", and TotalWeek1 >workWeek1, then CompTime1 = 0
However, If my ExemptStatus = "NonExempt", the text box txtCTOused1.Text should be Enabled,
And If my ExemptStatus = "Exempt", and TotalWeek1 >workWeek1, then CompTime1 is calc as
CompTime1 = (TotalWeek1 - WorkWeek1) * 1.5
If strExempt = "Exempt" Then
Me.txtCTOused1.Enabled = False
ElseIf TotalWeek1 >= WorkWeek1 Then
CompTime1 = 0
Else
Me.txtCTOused1.Enabled = True
CompTime1 = (TotalWeek1 - WorkWeek1) * 1.5
End If
lblCompTime1.Text = CompTime1
'calculate PTO used when timeworked is less than 40 hours per week
Dim PTOweek1 As Double
Dim CTOused1 = Convert.ToDouble(txtCTOused1.Text)
If TotalWeek1 >= WorkWeek1 Then
PTOweek1 = 0
ElseIf TotalWeek1 < WorkWeek1 Then
PTOweek1 = WorkWeek1 - TotalWeek1 - CTOused1
End If
lblPTOused1.Text = PTOweek1

Well, I wouldn't really use hard-coded strings to check for Exemption status. It's not culturally independant. I'd use some other data type to represent status information in the schema.
You've already got the logic layed out in your post, but it's messed up. You've got conflicting expressions for the same condition. I think I've fixed it, but it's your requirements, so double check the logic.
Also, to keep it simple, I'd avoid using ElseIf statements until you're more proficient at this.
These are your (fixed) requirements. You should be able to easily code the If block using this:
If my ExemptStatus = "Exempt" then
the text box txtCTOused1.Text should be disabled,
If TotalWeek1 <= workWeek1, then
CompTime1 = 0
Else
' TotalWeek1 > workWeek1
CompTime1 = (TotalWeek1 - WorkWeek1) * 1.5
End If
If ExemptStatus = "NonExempt", then
text box txtCTOused1.Text should be Enabled,

Hi, I am new in .Net environment and designing a small desktop application. Due to the limitions with combobox I want to design a custom combobox with following additional features :
1.Borderless
2.Reduced height
3.Custom image for drop down arrow
Can anyone guide me how to customize combobox to add these functionalities. I will appreciate if someone could forward me an example.
Thanks

You would need to make the control owner drawn and draw your own arrow, etc. Not a straightforward task, but perfectly doable.
