Im trying to use DateTimePicker function and save the date to an access database. Everything is working somewhat how I want it to but not 100% yet. Here is my problem. When the program is running if I click on the datetimepicker and select a date and click my save button the date IS saved to my access database as it should.
but if i run the program and don't ever click on the datetimepicker (because it is already on the correct current date) and click my save button the date doesn't get saved to the access database. The closest I have gotten was to enable the ShowCheckBox option, If i run the program this way and select the check box but dont select a date then it will save the date to my db.
But I really need it to be able to save the date to the db without the user ever clicking on the datetimepicker. Is it just a simple line I'm missing? Im pretty new to this but Ill try to explain anything the best I can if you have any further questions for me.
I have 2 Forms.Form 1 is main and holds a button that should show msgbox with date that is selected on datetimepicker which is on Form 2. Date shown on msgbox should be in short format (dd.MM.yyyy.).On program start datetimepicker should be reset to today and msgbox should show today date unless user selects another date on Form2. If user goes to From 2 and changes date Form 2 should save new value and msgbox should show it after button click on form1. How do i do this?I made myDate parameter in settings of type "DATE" and i didn't set a value.on form1 load i have:my.Settings.myDate = Today on Form2 load i have: datetimepicker1.Value = my.Settings.myDate on Form2 closing i have: my.Settings.myDate = datetimepicker1.Value
This sets date on picker correctly, but when i go to form2 and change value, then close form2 and reopen it it still shows date that i have chosen, but msgbox shows initial value.
I want to save datetimepicker value of date and time in two separate text files. Currently, when I select a date from datetimepicker and save it in a text file it saves both date and time as below:
5/11/2011 8:25:06 PM What I would like to happen is as below: Datefile.txt saves 5/11/2011 Timefile.txt saves 8:25:06 PM Alternative solution that can work for me would be, if the time (only the TIME) can be modified after saving as below: saved datetime into text file is 5/11/2011 8:25:06 PM
How can I modify the time only to say 12:00:00 PM. By doing so I would like to keep time as 12:00:00 but date can be changed by the user using the datetime picker.

i am using Visual Studio 2008 and VB.NET 2008 and SQL Server 2005 as the database. I just finished designing & writing codes for a customer information and , however after it has been connected to the database only one of the datetimepicker can be click, and the rest of the function including in the form are not working!it seem that the form stuck and NOT responding. i cant even close the form (X button), so i have to stop the process using compiler (visual studio 2008), however if i press the 'Delete' button before the 'Add' button, it will successfully delete the data.. but if i disconnected the form from the database, (disabled the form_load codes [put 'quote']) the both of datetimepicker will work and able to view the date interval (after pressing the 'Calculate Period' button) in addition how to make it appear automatically in screen without using the button? below are the code, I try to make some other form.. but it is still the same

How to use a DateTimePicker to query a database table. Basically, when a day is chosen on the DateTimePicker, I want all the database entries for that day to be populated on Datagridview. My Datetimepicker name is datetimepicker1. The datagridview name is dgv. The database table is called QCAuditing and the row in the database, that has timedate, which I want to use for query is called date. I was wondering if someone can point me to the right direction here.
View 1 RepliesI have an issue with date format in my SSRS. I am saving date from DateTimePicker to database. From there I am taking display in my datagridview using following
dgv.items(0,2).value=Format(Cdate(dsSaver.tblInv.rows(0).items(0)),"dd-MMM-yyyy")
This displays it correctly (04-Nov-2011) but when I take date from the same database to my SSRS using
="Dated: " &Format(cdate(Fields!InvDate.Value),"dd-MMM-yyyy")
It displays it like 11-Apr-2011.
I have tested all winforms fare displaying it right but all SSRS are displaying it wrong.
OK, before I throw my laptop out the window... I need to insert data into my Access Database from my VB.Net2005 application. I have written and re-written this code, trying everything I can find from the web and I've had no luck. I'm getting a {"Data type mismatch in criteria expression."} error on the ExecuteNonQuery line - I'm fairly certain that it's the DateTimePickers, as I rem them out and the code works fine. However, I've tried everything - changed the column in my database to Text, changed the .Value to .Text, .Value.ToLongDateString, and every time I'm getting the same error. One of the things I read on line was that I need to use parameters in order to pass the DateTime - I need to pass the Date and Time (date format is not important, but I require the hh:mm:ss format for the time). The fields currently default to the current date/time which is perfect, but I read that depending on how you pass the data, you may run into problems if the user does not pick the drop box (leaving it as the default).
[Code].....
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.

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.
I use Visual Basic 2008 I use bound Datagridview I use mysql database If i run this code, everything on the screen ( in the datagridview) neatly Updated.But when I look at records in the table "stock" always the first row (0) of the DataGridView not updated in the table "stock"All the other record are updated with where in the datagridview! This always happens!!!How can fix it?
myAdapter2.SelectCommand = myCommand2

MyAdapter2.Fill(MyDataset2, "stock")
