I have asked this question before and used the soln but for some reason it just does not work this time around. Hopefully someone else can see the error/missing element. Iparse a date that is in string format and would like to convert it to a datetime format but cannot figure out how to do this. The date appears as such:

I'm having a problem converting a string to a datetime format. the string is depicting an hour, for example 08:00, but in the mysql database it stores that as 2008/00/00 00:00 any idea how to solve this?
[Code]
I am getting this datetime format in an xml file:
2012-06-14T11:15:41.587-07:00
2012-06-14T10:49:32.397-07:00
2012-06-11T11:10:49.2-07:00
I believe I understand some of it, please correct me if I am wrong:
2012-06-14 = date
T = time identifier
10:49:32.397 = hour min second milliseconds
-07:00 = I have no idea
I need to convert this to something I can sort on for my datagrid view.
When I try something like this:
Console.WriteLine(String.Format("{0:d/M/yyyy HH:mm:ss}", "2012-06-14T10:49:32.397-07:00"))
I'm getting the original string back out with no conversion.
I'm pulling a saved DateTime using
Dim testDate As DateTime
testDate = rsQuery.Fields("ScenarioDate").Value
I have written this code and tried running it but I am getting errors in the code segments below. The error says "conversion from string to double is invalid". whereas the calculation for 'y' is an addition so should not be giving the value it is giving at the moment. ICCPtotcircuitres is also returning 'nothing'.
Private Function iccptotcircuitres(ByVal x As String, ByVal y As String, ByVal z As String) As String
Dim Res As String
Res = x + y + z
iccptotcircuitres = Res

I have two datetimepickers on my form to set a start date and end date for a SQL server database query. I am passing these dates with parameters to my query from the .Value of the datetimepickers. When I run the program, the code returns an error of "Conversion failed when converting datetime from character string" I am not converting anything in my code. It is my understanding that the StartDatePicker.Value is already a datetime and does not require conversion.
Here is some code:
'Define Wages_Query
Dim Wages_Query As String = _

" SUM(COALESCE(STWag,0) + COALESCE(OTWag,0) + COALESCE(Shift_Diff,0)) as [TotalWages]" & _

Need to convert a string to normal datetime format so it can be correctly inserted onto a datetime type field. String Format: 4/21/2010 4:43:03 PM Example: 2010-04-21 16:43:03.000 I have clarified question: The need is to change format and not type.

View 3 RepliesIn my VB project I am returning an SQL datetime field to a date variable mdtCreated = CType(oReader("dtCreated"), Date) In an example it returns mdtCreated as #5/13/2011 2:59:43 PM# which is correct. Later on I want to show this as a string to dd/mm/yyyy format. I have tried mdtCreated.ToString("dd/mm/yyyy hh:mm:ss") But that returns "13/59/2011 02:59:43". I want it to return "13/05/2011 14:59:43" How can I achieve this?
View 2 RepliesI wish to convert my string in format dd/mm/yyyy hh:mm:ss to a DateTime of the same format.
Dim ukCulture As System.Globalization.CultureInfo = New System.Globalization.CultureInfo("en-GB")

When I step through this code the variable myDateTime is 05/18/2010 23:42:10 it appears that the dd/mm is the wrong way around and I cant work out how to correct this.
I can't seem to be able to convert a string that contains date value of "100714 0700" (2010-07-14 7am) to a date format in vb.net 2005.

Dim provider As Globalization.CultureInfo = Globalization.CultureInfo.InvariantCulture
strPickupDateTime = DateTime.ParseExact(txtPickupDate.Text, "yymmdd", provider)
I get back "1/14/2010 12:07:00 AM". How can I get a value of "2010-07-14 7:00"?

View 2 RepliesI realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.

I want to to make date format dd/mm/yyyy with access 2003

The project is to use a transaction to update something. Since I run a dnd game I used it to update levels of a character. Selecting the character works perfectly fine. Validation of the level works fine. Actually trying to update it gives me the error "Error: conversion from string "" to type Double is invalid". This is getting frustrating because I cannot find the involved string nor do I have a double anywhere in the PROJECT let alone in the code.I have tried adding a global variable to the transaction form to set the level for update in the update statement, changing the level type and that's about all I could think of. I don't know where to begin looking for the error's source unfortunately. [code]

View 3 RepliesI'm trying to make a card game where the user chooses either Clubs, Hearts, Spades, Diamonds or Joker and then the computer randomly chooses a card to counter and then depending on the formula of what beats what the scores are tallied.
Here is the:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Now I pick a card and the computer picks a card and it displays the winner but then immediately it sends me to the coding highlighting lblcomp.text += Val(0.5,1, or 4) saying "Invalid Cast Exception was Unhandled" "Conversion from string "" to type 'Double' is not valid.
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.

View 4 RepliesI'm just converting a date to a string but I'm getting this error. It's not listed as one of the normal exceptions to the datetime.tostring method. Googling around, it looks like it's an actual bug where it thinks StartDate is an int--but that's no help to me, as I just need to convert the date.
dim StartDate as nullable(of date)
dim Date1 as string
if not StartDate is nothing then
Date1 = StartDate.tostring("yyyy-mm-dd")
