How To Get Values Of DateTimePicker Selected Controls
Apr 3, 2010
I have two datetimepicker controls on my form:
dtpPickup and dtpReturn
I need a way to ensure that the dtpReturn date selected is after the dtpPickup, and not before. How do I do that? And also, how do I get the values of the datetimepicker selected controls? Also, how can I set the values of the datetimepickers to these two private variables?
Private mdatStart As DateTime
Private mdatEnd As DateTime
It will not let me save them with the Sub for the date time pickers.

I 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.

I'm using this to set the default values of the DTP controls on Form_Load:
Dim dtNow As Date = Now()
dtpStart.Value = dtNow.AddDays(-7)
dtpEnd.Value = dtNow
The problem is, when those values are grabbed from the DTP controls, Access is treating them as wrong datatypes.However, if I manually rechoose the same dates, the SQL statement will work.So, what seems is happening is that it isn't recognizing the initialized values as valid date/time values until I physically choose them.Anyone know a workaround for this or what is really going on and how to resolve this?

I have a database that has null date values in it. When I call the columns from the database with the null datetime values and display it in the datetimepicker text box using a dataset, theres always values in the datetimepicker text box. It sets everything that was in the database with null values to the current date. This is what i have..
DateOPStartedRevisionDateTimePicker.Text = ds.Tables(0).Rows(0).Item(13).ToString
I just cant figure out a way to get the datetimepicker text box to display nothing if the values are null in the database.

I have a block of code below that allows the user to create new buttons at runtime at the click of the right button at runtime.But i am wondering how to detect the selected button on the main form and then the user can delete the selected button at runtime.
The other thing the user can do is also to drag the button around the win form when in runtime. Cause i'm new in VB and i am exploring this part. the code that i have is here and it is created by one of the member in msdn.

I have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

i have a form with 3 combo boxes. The value of the combo boxes generates a sql query with 3 parameters. The sql generates a RDLC report.
For example:
Combox1 with values(v1,v2,v3,ALL)
Combox2 with values(v1,v2,ALL)
Combox3 with values(v1,v2,v3,4,ALL)
Me.ExampleTableAdapter.QueryWithParams(Me.ExampleDataSet.Table, Combobox1.SelectedIndex, Combobox2.SelectedIndex,Combobox1.SelectedIndex)
QueryWithParams:SELECT * FROM Table WHERE Column1=@c1 AND Column2=@c2 AND Column3=@c3 Ok the problem is when the selected value is ALL in the combo X, i cannot get the values because i must change the query and kick out the parameter.For example:If the combo1,combo2,combo3 have the values ALL. I don't need parameters.SELECT * FROM Table IF the combo1 is ALL.SELECT * FROM Table WHERE Column2=@c2 AND Column3=@c3 If combo1 and combo3 are ALL SELECT* FROM Table WHERE Column2=@c2 Then in code I look which is the selected value of the combo and upon it i do the query.Is there a way that i do this thing without generating all 8 types of queries?PS. I cannot use stored procedures because i'm using SQL Server Compact

Is there a way to to combine line's 1 and 2? I only want to loop through a list of the selected items in this listbox. This works just fine, I just wondered if there was a collection of selected values returned that I could use to avoid having to do it this way.
For Loop1 = 0 To MyListBox.Items.Count - 1
If MyListBox.Items(Loop1).Selected = True Then
...
End

I have a little problem. Basicly, I have a ListBox, TrackBar, TextBox and 2 Buttons. What I want now is that:
1. If user clicks on Button1, the program will add text from TextBox to ListBox (I know code for that one).
2. When user clicks on ListBox item, ListBox item selected, and then clicks on Button2, program will set the value of SelectedItem to TrackBar. Here's an example:
User writes "Value is 50." in TextBox, clicks on Button1 and program adds "Value is 50." to ListBox. Now user selects ListBoxItem and clicks on Button2. Program sets TrackBar value to 50.
