I'm trying figure out the VB code necessay to initialize the DateTimePicker object at program startup.I've got this subroutine, which creates the datetimepicker:
Public
Class
Form1

I would like to create ToolStripe on my DGV form with 2 DateTimePicker tools. And when user open form those tools will display by default date:
- first DateTimePicker will show date on 2 month early then current date;
- second DateTimePicker will show current date.
Is there a way to remove default date for DateTimePicker? It defaults to today's date and I couldn't find a way to remove it. For example - when user pulls up a record and there is no date in the field - it shows today's date which is misleading. We could have the cases when the field is not filled in yet and user might think that it has today's date in it when it's actually Null. Basically I need for date fields to be blank initially. We also have the other date fields that might have dates in it but we'd need to remove the value completely. Again - DateTimePicker doesn't allow it. We tried to use masked field as well but run into the problem where existing values with single month/single day (like 1/1 for example) were converted wrong with MM/dd/yyyy mask.
View 12 RepliesI am using the sample datetimepicker code from the Microsoft web site in a databound datagridview. This works fine if I use the combobox dropdown button and select a date. Is there a way to use today's date by default and not specifically selecting it?

i have a problem on setting the default value of my date time picker. i have created this application
[code]...
and my problem is i want to set the default value of my DateTimePicker(dtpDate) depending on which date was clicked on the calendar in Main Form. i've been posting this program of mine this past few days now. i just really need to finish this for my upcoming thesis defense.
I have a combobox which contains a sample of names selected from a table.Currently the default name displayed in the box is the 1st name found in the table. What I would like to do is display the name of the person who is doing the selection as the default. The name is stored in a public variable 'PubName' and I do not want the user to be able to type into the combobox themselves.Is this possible?
View 2 RepliesI am developing with VS2010 VB.Net and a SQL '08 dbase. I have a DateTimePicker control that by default displays the current date. If you ignore the DTP control and accept what the default is and save the record, in the database table, the value for the date is 'NULL'. I delete the record out of the database and re-create the record in the UI, but this time, I click on the DTP control and actually click my mouse on the current date or any date and then save the entry and it saves to the database properly. I guess what I am after is if a user instantiates the UI form to perform data entry and accepts the current date in the DTP control without clicking on the control, the value is saved properly to the database.
View 1 RepliesI am traying to use the DateTimePicker to extract days diff from a date selected on DateTimePicker1 to a date selected on DateTimePicker2. I have no problem substracting the daydiff in numbers of days. The problem I have is that I need the DateTimePicker to tell me how many of those days are weekends (friday, saturday) and how many are weekdays.
View 2 RepliesWhen the .net framework cannot be found, the following message is displayed:
"The application failed to initialize properly (0x00000135)"
Is there a way to make it a tiny bit more specific (instead of writing a wrapper in another language), eg. by telling the user about the .Net fx?
I have alot of forms here who need 10 or more seconds to load when the method InitializeComponent() starts to run. It have a lot of pics for that is too slow to load. I need to do a loading screen to show while the initializeComponent() components is running.

I was wondering what was the proper way to create a If statement for if the datetimepicker date is greater than 2 weeks from the current date.
I was thinking something along the lines of
If (datetimepicker.value > DateTimeInterval.Day(14))
but I am not sure the correct way.
I want to get the date value from datetime.now till the selected value from datetimepicker. Ex.
date Today is 08/09/2011
selected date from datetimepicker is 02/08/2012
I want to show the dates between the 2 dates mentioned. For example I want to show the value of
09/09/2011-Firstmonth
10/09/2011-SecondMonth
11/09/2011-thirdMonth
12/09/2011-FourthMonth
01/09/2012-FifthMonth
Until it reached the selected value from datetimpicker.
I have a date time picker where the dates available to be selected on it is affected by the choice made in a combo box above it. If the user selects "Express Air" in the combo box for example, the minimum date in the date time picker must be either Today or Tomorrow. Nothing before, nothing after. How do I go about this? I tried:
Private Sub DateTimeExpressAir()
If cmbShipmentMethod.Text = "Express Air" Then
DateTimePicker1.MinDate = DateTime.Today
End If
End Sub
If also possible how do I set the MAX date to like, tomorrow, or 6 days after today, etc? DateTimePicker1.MaxDate = ??
But no success. I am using Visual Basic 2008.
I am trying to take a date from a DateTimePicker, add so many days to it, then display the new date.
So far i have got:
Private Sub CalculateDateDue()
Dim RaisedDate As DateTime
Dim terms As Double
[code]....
But it doesn't seem to perform the .AddDays function, but passes over it without any problems.
terms does convert to the right number, so i know thats not an issue.

View 12 RepliesWhen a user selects the datetimepicker, or types in the date in the text box, the calendar then highlights that date (for instance 02/02/2009) and puts the date in the text box.
If the user deletes the date from the textbox and then selects the drop down arrow again to show the calendar, the 02/02/2009 date is still highlighted. The user can select a different date or type in a date (including the highlighted one) - no problem. But if they wanted to select the same date they deleted, they cannot. No error message, it just leaves the text box blank.
Yes, it's very rare that that happens and they can highlight a different date, then go back in and highlight the 02/02/2009 date in a matter of two clicks but they want it fixed .
Not sure how I go about getting the calendar to clear the highlighted date once it has been deleted from the textbox?
My datetimepicker hangs up at midnight and does not roll over to a new date.
