DateTimePicker Exception ArgumentOutOfRangeException - Up And Down Keys To Change The Month
Nov 22, 2006
I have an unbound DateTimePicker Control on a form. When the form loads the control shows 2005 - 01 as expected. I can use the arrow keys left and right to switch between highliting the year or the month. Pressing the up and down keys to change the month doesn't work an exception is raised. I don't understand why. I started a new project. Just added a DateTimePicker and the following code.
I changed the date of datetimepicker format to yyyy-mm-dd in custom format...but it displays 2009-00-22...the month part is not showing the month of the exact month..how to change the format of the date?
i have a simple VB.NET application with a datetimepicker-control. Now i want that the datetimepicker always shows this format 01.07.2009, always the first day of the month

Im trying to change or increment the month value of the datetimepicker using a command button. I tried to use the sample code from MSDN site but I was only able to increment once. I want to increment the value of the month everytime you click the command button. Do I need to use a loop statement? If so, how do I do that? I used this code below which can only increment or change the month value once but when you click the button again, no changes will be shown.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
'DateTimePicker2.Value = New DateTime(2001, 10, 20) DateTimePicker2.Value = New DateTime(DateTimePicker2.Value.Year, DateTimePicker1.Value.Month + 1, DateTimePicker2.Value.Day) End Sub
How to set the mindate of datetimepicker base on a month and year that i want ? Lets say my datetimepicker value when i the program first run is July 7, 2010, now when i click the button i want that the minimum date of my datetimepicker is August 7, 2010, dont mind the day what is important is the month and year.
problem 1: By default the textbox property of textbox is empty and if we want to show something so we change the text property of text box. right. Similarly is it possible for datetimepicker? i mean that date is always appear in datetimepicker both at run time and at design time, but i want that when my form is loaded so datetimepicker appears clear just like textbox is empty, and when i select some date then that date is display.

I want to enter Year, Month & Date in a separate TextBoxes to get a Function work as these 3 have to be given as parameters for that Function. I've been using 3 different TextBoxes to enter the Year, Month & Date. Now, I thought of using either a DateTimePicker / MonthCalendar for this. how to get it done. By clicking a Date in the DateTimePicker how can I get the Year, Month & Date separately fed into the Function? [Code]
Is there any way of getting the year, month & date separate from the DateTimePicker / MonthCalendar?
I have a datetime picker which format is yyyy-MM(2011-09) and I need to choose all the records of a particular month, I use this like query but doesn't display anything
The exception message I am receiving is this... "Year, Month, and Day parameters describe an un-representable DateTime."
Now I've traced my values being passed and everything is correct. Values loops through 1 to 12 but still I continue to receive an exception. Only way I can avoid this is by throwing a Try, Catch statement around where I'm passing over the value.
Here's my code..
001 Dim Calendar(11) As AppointmentBookControl.AppointmentBookControlMonthlyOverviewCalendarControl 002
[Code]....
Line '011 .Month = i+1' is where the problem is located. The values for (i+1) maintain within the bounds of 1 through 12..
I'm changing the backcolor of the monthcalendar to 208; 211; 217, but the backcolor of the monthcalendar doesn't turn "grey" according the given RGB. Instead it stays white.
I also have an array; a combobox and a variable called: TimeInterval. here is the code I use:
Code: Dim ReadingFrequency(7) As Double Dim TimeInterval As Integer Private Sub CustomizeGraph_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[code]....
What I want is to change how much the datetimepicker increments, when you click the arrows, depending on the value that is entered in the combobox. For example, if the user has 2 hours in the combobox, the datetimepicker will increment by two hours and won't let the user change the minutes. If the user selects 15 minutes, the minutes will increment by 15 on the datetimepicker.
How to change the background Color of the "Box" (that shows the day, Date etc ith an Arrow for Dropdown calendar) that appears in the Form1 when you add the DateTimePicker to the Form. This I want to do since the white color of this DateTimePicker Box gives a horrible look when I make the Form with a different color and I want this DateTimePicker to have the same color as the color of the Form where the dateTimePicker lies. I am learning Visual Basic using MS VS 2005.
I found this on the web after i was searching on how to change the background color of a dateTimePicker the actual background of the control not the background of the calendar within the control. I have my computer windows set up with a green color so my eyes get no so much of a workout, instead of white like is default. so when the dateTimePicker is displayed in the program im building it is green, unless i set my windows color to white in the appearance/advance/window
Can we change the style of dtpicker in VB.NET form. i.e. I want to change its style to 2D or When I click in text box then the dtpicker should be open. If it is possible then how can we achieve this.
I am trying to make the transparency of forms change in someway. I tried making a track bar with checked boxes and that didn't work, and I tried the ALT with the UP and DOWN keys,I tried to change the code so it would fit in with my program and that didn't work ether.
I want to change the Forecolor and the Font color of the DateTimePicker. (The one Narrow white window with Black font which appears on dragging "D.T.Picker" control onto the "Form").
So far, I couldn't do it.
I found the same question (by someone on 31st Aug 2007) and answers by Figo Fei in the forum. Figo fei said, "It is truly not possible to directly modify the forecolor of the DateTimePicker which is concealed in its implementation. However, there is a workaround to change its forecolor through own-draw mode in a custom control inherited from dateTimePicker.". And he gave the code which looks like - for me - either VC++ or VC#.

I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
I have the following code that sets a DateTimePicker as Readonly (and it works well). But to give the full effect of being readonly, I would like to implement the ability to change the Backcolor and disable the ability to use the calender. how to change the Backcolor and disable the Calender?

I've got a datetimepicker control on a vb .net 2008 form. I have set it to show a custom format of "dd/MM/yyyy". The problem is this: - when i click on the arrow button, a small calendar is shown in which i should be able to select a date. The only way i can do that is by using the arrow keys and pressing Enter. Clicking on any date value inside this calendar doesn't do anything.How can i make the value of the datetimepicker change to what i have clicked inside the dropdown calendar?
I populate a hash table with the name of a control as the key and the control itself as the value using the following code that loops through my code on start-up:
Private Sub Populate_Hash_Table() For Each ctrl As Control In Me.Controls For Each member As Control In ctrl.Controls
[Code]....
This method works effectively, but the only problem is I seem to get a preformance hit as it takes a second to set the current control to false and the new one's visibility to true. What way should I modify my code so that it works more efficiently?
Currently i have a ReturnSystemDate in a module, so that whenever i need the current date and time i call this method, however my data is saving as in 1 format and displaying in another. I have my variables set up as dateTime to store the current date and time, when calling System.dateTime.now.toString() i get 11/08/2010 Time, however when casting to Date as in CDATE() i get 08/11/2010 time. How can i stop this?
