Basically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.
I didn't understand something about DateTimePicker control, on one of the site i found the Private Property Hour() as integer this property was used. And inside it was:
I have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.
I'm creating an Microsoft Office 2010 add-in ribbon with a bunch of controls on it. I am able to add things like buttons, TextBoxes, and Labels. :-) I am not, however, able to add the one control I need, which is a DateTimePicker.

If you enter 11 for instance into the year component of the date then tab off the control the text returned to the validation function is the text before the year was entered rather than the new text.The problem can be overcome by making the control invisible then visible. This has been the case since Visual Studio 2003, it would seem to be a bug.
Wasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
I am having the following problem, when the user wants to use the DateTimePicker (DTP), the date box shows in the middle of the screen. Then if the user wants to select a date he cant, instead the date box goes away and the DTP value remains unchanged. This is not always happening, sometimes it works fine and sometimes this happens.Please go to the link below for an image (you can see that the DTP control is on the left while the date box is to the right):[URL].. application is being run from a server to a local client on the user machine, I dont know if this has anything to do with it.
I know that you can create custom formats for the DateTimePicker control, and I've googled this but is there any way that you can allow a user to only select Sunday dates in a Month with this control?
I 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.
I have a DateTimePicker control that returns the current date.My usage is like this: DateTimeInput.Value.ToString("MMMM dd, yyyy")Please note that I need to get the date in the specified format.I just don't know how to add 1~2 years to the date.I mean if user selected January 01, 2009, I want to get January 01, 2010.So how can I add just 1 year or 2 years to the year of returned value?
In my application i like to include the Birthday's schedular... i.e if i click/double click the date in DateTimePicker or in MonthCalendar control an inputbox opens in which we have to enter the birthday person's name to the selected date....

The backcolor of a default DateTimePicker control seems to be Color.White, but can this change based on a users theme colours and how do I find out what it is currently set to?(There is no backcolour property and DateTimePicker.DefaultBackColor returns SystemColors.Control which is not actually correct)I guess that if someone can confirm that this can't change then I am safe to hard code it? The basis of this question was not actually a typo, it was the fact that BackColor does not show up in my DateTimePicker control intellisense.
been a long time since i came to the forum. i use to program a lot in vb6 but its been a long time since i did it so im really rusty. now that im trying to get back to programming, im finding it a bit of a challenge in vb2008... i have this question, im using a datetimepicker control to select dates in a calendar. what im trying to do is disable the textbox in the datetimepicker so that the user can only use the drop down calendar to select the date and not enter the date manually! does any one knows how to disable the textbox in the datetimepicker but still be able to select a date from the calendar???
Is it possible to disable the dates that appear before todays date in a dateTimePicker control?I want to put in some validation so that my users can only select days in the future...ie a future appointment date?
If DateTimePicker1.Value.Year <= DateTimePicker2.Value.Year Then 'dtp2 = expiry date If DateTimePicker1.Value.Month <= DateTimePicker2.Value.Month Then MsgBox("Expiry Date Correct!") Else MsgBox("Expiry Date incorrect!") End If End If
How would I get it to check the date? Datetimepicker1 is the current date, while Datetimepicker2 is the expiry date.
I am using access database to store my datas?I have used a datagridview to present the data to the user.I want to give the date filter option to my users.How can i bind the datetimepicker control with my datagridview.one of my datagridviews coloumn is contains date string.
Private Sub btnViewAll_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnViewAll.Click 'Declaring connection string Dim objConn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source = D:queDB.mdb")
I have a date field in my dataset, my datetimepicker is bound to it. When the form loads, the datetimepicker is default to todays date if there is no value stored in the database. Right now I'm saving by the tableadapter.update(dataset) method. Is there a way to make it write the default value (today) of the datetimepicker even if the user doesn't select a value because if you make no selection it saves nothing in the database and the user may think it's ok because there is a value (today) shown by default.
If not, what is a good way to display the datetimepicker as empty so the user will have to choose a value, or how do you communicate with the user that the date shown is not going to save?
I'm using the following code to fill a DataGridView:
Dim conz As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:BdadosCV_PARTS.accdb;Persist Security Info=False") Dim cmd As New OleDbCommand("SELECT * FROM PECAS_IN WHERE Data >= ?", conz) Dim da As New OleDb.OleDbDataAdapter(cmd)
[code]....
The field 'Data' has the format "dd-Mmm-yy" on the Access database. The code allways fails with a type mismatch in the criteria expression.I already tried
I'm trying to accomplish that every time I click + on binding navigator, datetimepicker get the today date. Not only on the form, but on the binding source also.After previewing saved data, the date cell of datagridview is empty.That doesn't happen when I select wished date manually on the form, only when I enter it in code.
