I have an Sql server 2005 table called Emploeefl with 2 fields, EmployeeCode and Date of Birth. The data type for the date of birth is Datetime. I have a Date time picker on a vb.net 2005 form called dtDateOfbirth. When I click on the save button I get the error message "Conversion from string 'yyyy/MM/dd' is not valid. Below is the code
Dim newQE_Date As Date newQE_Date = Format(Me.dtDateOfBirth.ToString, "yyyy/MM/dd") 'newQE_Date = String.Format("2008/09/10", "yyyy/MM/dd")
The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.
1: Created a GroupBox 2: Put a DateTimePicker in the GroupBox 3: Put TextBoxs in the GroupBox 4: Changed the DateTimePicker to look like this: A)Checked - False B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
I am having a bit of trouble with using the date/time picker in a project.It is a program for calculating travelodge hotel accomodation prices. The price for a weeknight is 40 but weekends increase to ï¿½50.The code which I wrote is this:
For i As DayOfWeek = dtpArrival.Value.DayOfWeek To dtpDeparture.Value.DayOfWeek If dtpArrival.Value.DayOfWeek = 1 Or 2 Or 3 Or 4 Then PriceDecimal = PriceDecimal + 0[code].....
It does not work obviously because I am using the date/time picker for arrival date only. I think I need to use some other value which i would presume is something like "If DayOfWeek = 1 or 2 or 3...." but this will not work.
Would it be possible to display todays date with a time of 23:59 in ctime in a textbox? i.e. 25/05/2012 23:59 in ctime? I use the following coding to display the current date and time lbldate.Text = Date.Now.ToString("dd MMM yyyy HH:mm:ss")
I have create a Car Rental application, where, based on two DateTimePickers, the number of days and, by extension, the total cost of the Rental can be calculated. I managed to get my DTPs working without much problem, however, my Min/Max dates do not seem to function.
Also, I want to create a condition where if the user returns the car on the same day, they only pay 60 percent of the normal cost. I have a basic idea of how to do this, but, once again, I am not quite able to get it to work.
Here is my code:
Private Sub Calculate_cmd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Calculate_cmd.Click
'Declare Variables for DTP Calculations. Dim DatePicked As DateTime = Picked_dtp.Value Dim DateReturned As DateTime = Returned_dtp.Value Dim intPicked As Integer Dim intReturned As Integer Dim intDays As Integer Dim intRate As Integer Dim intTotal As Integer
' Set the MinDate and MaxDate. Picked_dtp.MinDate = DateTime.Today.AddYears(-1) Picked_dtp.MaxDate = DateTime.Today Returned_dtp.MinDate = DateTime.Today.AddYears(-1) Returned_dtp.MaxDate = DateTime.Today
'Read Data off of DTPs. intPicked = DatePicked.Day intReturned = DateReturned.Day

Does anyone know how I would go about embedding a DateTimePicker in my DataGridView?I've tried this piece of code but it looks like DateTimePicker isnt a valid GridView control - is it a lot of hassle trying to implement this?

I have created a text box....a button and a date time picker control. I have showed the calander control on click of the button event....when a value is selected in the datetimepicker the value should be showed in the text box...I have done this....in the datetimepicker value change event
But then I want that the datetimepicker control to hide again...but this code I cant write in the value change event since if I write the hide code in datetimepicker value change event it will hide it every time...cant write in lost focus also since it will have to wait till the focus is lost. cant write the code in text box value change event since the value will be changed after every click in datetimepicker I want to write the code when the value in calander is doubleclicked...

I am working with a date and time picker on one of my forms. I am wanting to have the user select a date and then that date will be output to one of my reports along with other information.The way i have been doing this so far is like this:edoc.Worksheets(1).cells(13, 4) = patient_frm.txt_fname.TextI need to be able to grab the date that the user selects and output it in much the same manner. However i have tried the following and i get no output at all.
how I would go about subtracting todays date from a specified date. For example, I want a lable control to say "9 Days Left To Register" where 9 is the dates is todays date subtracted from registration date.
Is there a way to check if the date time picker has been changed? I have a date time picker set to allow a person to put in their date of birth and I have it set to no greater date than 12/1/1992, but I need to check that the user has actually selected a date before the form is submitted. Can it be checked?
Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged mycommand = New MySqlCommand Dim daMyName As New MySqlDataAdapter

I have set a custom format for DTP control to dd/MM/yy. lets consider a real time scenerio. I have a form to enter Invoices for that i have following controls on my form 1] DateTimePicker, 2] CustomerName ComboBox, 3] Quantity, 4] Amount o.k. the Custom Format for DTP is set to 'dd/MM/yy'. When i first add entry i set the focus to DTP Control After changing date user moves focus to ComboBox then Quantity then Amount & Finally Clicks Save Button. And again hits Add Button and the cycle continues.
Now when user changes 'month'in DTP & go ahead and save the entry when he add another new entry the focus is on DTP however in the month region of DTP where it is expected in 'Date' region of DTP b'cas it is not likely that user will change month every time but he may change Date every time. This enforces user to mannualy select the desired region (either by Left Arrow Key or by Clicking Mouse button in the desired region). So after receiving focus i want the cursor tobe in the 'Date' region of DTP. Kindly help me writting correct statement to set focus to the control in the desired region (section) in DTP control.
When the form loadi set the format of datetime picker as "MMM yyyy" (custom Format) for only showing month and year.then i change the month using numeric key (pressing 2) so the month is Feb . again click the drop down of the Datetime Picker unhandled Exception occurs.because date is 31 and in feb only 28 days . For avoiding this i set the date as 01 as the value change .then the event occurs muliple times(recursively calling the value change event).
