Adding Time - Get Value Of Type 'Date' Cannot Be Converted To 'System.TimeSpan'
Jan 13, 2010
why did they make this so hard to do. Does anyone have any clear cut, basic 3-4 lines of code that can tell me how to add 2 time variables together to create a 3rd variable? I tried this but on Time2 I get Value of type 'Date' cannot be converted to 'System.TimeSpan'.
I need to take 6 user entered dates and compare them to a date pulled from a database & stored in a variable. If greater than 6 weeks, then some action needs to take place.When writing the code, I get the following message (before compilation). Value of type 'Date' cannot be converted to 'System.TimeSpan'. [code] Within my code the 'dt' in the line above is underlined with the error message appearing on mouseover. I have tried using CType, as in dt = CType(Session("dt_occurence"), DateTime) in the hopes that might work, but it doesn't do it.
But i am now trying to declare time however i keep getting an error because i cannot get the type correct. I tried the following but get the following error: "Conversion from type 'Timespan' to type 'integer' is not valid".
Dim DeliveryTime as DateTime Dim DeliveryTime as Integer
In my database the DeliveryTime type is set to Time(7) so i would assume there should be 'Time' which i could use to declare it, but there isnt. What is the correct type i should be using?
Here is my exact code. There error is Input string was not in correct format:
GraphDate4 = String.Empty DeliveryProducts = "{ name: 'DeliveryProducts', data: [" If DataReader4.HasRows Then
I have declared dob as date and the following code is to to call SQL server stored procedure but i cannot compile code because of error message (Value of Type 'Date' cannot be converted to integer).[code]
In the below code I am getting the following error on line If (Not hash.Add(Numbers(Num))) Then Value of Type 'Integer' cannot be converted to 'System.Array'.
Module Module1 Sub Main() Dim array() As Integer = {5, 10, 12, 8, 8, 14} ' Pass array as argument.
there is one problem here the root node on the line "GetDirectories(info.GetDirectories(0, rootNode))" here is the error "Error 1 Value of type 'System.Windows.Forms.TreeNode' cannot be converted to 'System.IO.SearchOption'."
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Me.BackColor = RGB(Rnd() * 255, Rnd() * 255, Rnd() * 255) End Sub
then i see this error:Value of type 'Integer' cannot be converted to 'System.Drawing.Color'
When I try and compile code in vb.net 2008 I get an error that says "value of type 'system.drawing.image' cannot be converted to integer. The error happens at piccolor.image GetDIBits(Form1.PictureBox1.Handle, picColor.Image , _ 0, Form1.PictureBox1.Height, pixels(1, 1, 1), _ bitmap_info, DIB_RGB_COLORS)
Here's the code that explains what piccolor.image is, it's a picturebox on form1 that has an image readpic(Form1.PictureBox1) Public Function readpic(ByVal picColor As PictureBox) GetDIBits(Form1.PictureBox1.Handle, picColor.Image , _ 0, Form1.PictureBox1.Height, pixels(1, 1, 1), _ [Code] .....
And Imports System.Runtime.InteropServices is on the top of the module, if u need more code then let me know. Also I wonder if there is a way to bitblt directly to a pixel array.
I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like:
FOREACH Month As TimeSpan in ContractRange.Months Do Calculations (Month.Start, Month.End) NEXT
Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?
Dim oURL As Uri = New Uri(e.Uri.AbsoluteUri) Dim favicon As Image If oURL.HostNameType = UriHostNameType.Dns Then
[code]....
The error is Value of type System.Drawing.Image cannot be converted to System.Drawing.Icon Is it even possible to make the favicon be the icon of the form?
Im trying to write a sub where a item from the first listbox (listbox1) is transferred to the second listbox(listbox2). When I try to call it on the button handler I get the following error:
im using an MDI parent form and MDI Child. how can i print the image that's inside a picture box that's inside the Child from a button that's on the Parent?when i try to use print preview or print dialog, i can't get it to recognize that the document is the picure inside the picture box. i've looked up this error message:Value of type 'System.Drawing.Image' cannot be converted to 'System.Drawing.Printing.PrintDocument'.[code]
I seemed to have have ruined my settings on VS 2010... I can't get the Shapes to work just after I had fixed the problem with the PowerPacks, and then it deleted all of my shapes I had on my form after I was tweaking the code and added another shape. And ever since, the shapes make errors and I can't change there colors. I've tried reinstalling VS 2010, and changing refferences doesn't work anymore. The title is the problem I have with trying to add a shape through the code in my project, here is the code for that:
Public Class Form1 Public Circle As New Microsoft.VisualBasic.PowerPacks.OvalShape() Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
I have been trying my hand at this for some days now and just cant get anything to work. Below is the code im currently using to delete a row from a database table, the problem when trying to build the project line 5 is giving this error about the value con" Value of type String cannot be converted to 'System.Data.OleDb.OleDbConnection' "
Dim con As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=Customers.mdb" Dim cnn As New OleDb.OleDbConnection(con) cnn.Open()
[CODE]...
I have also tried using this code below, but to no success. Im basically just looking for something rock soild that i can use to accomplish this task. Been stuck on this for quite a while now.
vb Dim s As String = strContents '<a global variable) Dim currentPos As Int64 = 0 Dim endPos As Int64 = strContents.Length - 1 '// A dictionary, used to count the frequencies Dim characterCounter As New Dictionary(Of [String], Int64)() While currentPos <> endPos '//
[CODE]...
Gives this error: Value of type 'System.Collections.Generic.KeyValuePair(Of String, Long)' cannot be converted to 'System.Collections.DictionaryEntry'.
to trace the days of a program installed in user's computer.However, the user can changes the system time of his computer to a advancing date. How can I get a SNTP time from internet to solve this problem?
The Now() function in VB.NET returns date and time which is different from the system time that I see on the right-bottom on the notification bar. It is 15 hours slower than the system time. Has anyone ever met this problem? I'm using .NET 2.0.
I have an SQL Server database with a table in it that has a column labeled DATE (datatype =date).The table also has a column labeled TIME (datatype Integer) that contains hours and minutes.I would like to be able to display the time in a datetimepicker also.
Would it make sense (remember I�m new to VB) to have the time as part of the date column?Doesn�t the date/datetime data type include time(7/24/1996 12:00:00 AM)?If so what is the best way to add the TIME column to the DATE column.I know I can go back to our other system (IBM iSeries) and combined the columns and transfer the data over again but that is chore (the transferring) and I want to learn how to do these kind of things without falling back on my IBM skills.It seems I should be able to add time to the DATE column of the table. None of the DATE data transferred over to this table had time with it.
been racking my brains on this one for a long time, and I've finally decided to ask the question. I had sevaral fields on a vb.net form which need to come together
