DateTimePicker Values And SQL Statements?

Jan 9, 2009

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?

If Statements - Program Look At 2 Different Values Then Return A Value

Feb 18, 2012

What I need to do is to have my program look at 2 different values then return a value.

Here's an example:

If my tube material = SA-214 and the tube gauge = 20 then my tube wall thickness = .032. The thing is I have 5 different types of tube material and 12 different tube gauges so based on which tube material is selected and which tube gauge is selected the tube wall thickness will vary. So if I select a TM of SA214 and a TG of 14 then my tube wall will be .076.

Displaying NULL DateTimePicker Values?

Jan 4, 2010

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.

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.

Oct 6, 2010

I am using Microsoft Visual Studio 2008 with VB.NET, and in class we were assigned this project: A procedure should calculate a 2% price increase on all red shirts, but a 1% price increase on all other items. In addition to calculating the price increase, the procedure also should calculate the new price. You can use the variables strItemColr, strItem, decOrigPrice, decIncrease, and decNewPrice. Format the original price, price increase, and new price in the lblOriginal, lblIncrease, and lblNewPrice controls, respectively.

2 SQL Statements The Same? Will They Produce The Same Results?

Aug 22, 2011

Are the following 2 SQL statements the same? Will they produce the same results?

sql1 = "SELECT * FROM [StudentDetials] WHERE ([Subject1] LIKE '" & Subject(0) & "' OR [Subject2] LIKE '" & Subject(0) & "') AND ([Day1] LIKE '" & TabDay & "' OR [Day2] LIKE '" & TabDay & "') AND ([Time1] >= '" & Time(0) & "' AND [ETime1] <= '" & Time(1) & "' OR [Time2] >= '" & Time(0) & "' AND [ETime2] <= '" & Time(1) & "')"

sql1 = "SELECT * FROM [StudentDetials] WHERE ([Subject1] LIKE '" & Subject(0) & "' AND [Day1] LIKE '" & TabDay & "' AND [Time1] >= '" & Time(0) & "' AND [ETime1] <= '" & Time(1) & "') OR ([Subject2] LIKE '" & Subject(0) & "' AND [Day2] LIKE '" & TabDay & "' AND [Time2] >= '" & Time(0) & "' AND [ETime2] <= '" & Time(1) & "')"

In my case they simply produce the same results but that's because of the data i'm using.
