What is the best way to convert the datetime to only char like below?
20090422230902590
I want to insert only date into the db but in the following statement that I've wrote which inserts the date in mm-dd-yyyy hh:mm:ss format.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & TimeLabel.Text.Trim() & "')" & "Update Blotter Set Name = UPPER(Name)"
I have tried the following code, however it didn't work.
InsertCmd = "Insert into Blotter (Name, Product, Date_Time) values ('" & NameLabel.Text.Trim() & "','" & ProductTextBox.Text.Trim() & "','" & (CDate(TimeLabel.Text.Trim().ToString("MM/dd/yyyy")))& "')" & "Update Blotter Set Name = UPPER(Name)"
[code]
I also tried format the TimeLabel as below but still didn't work. [code] TimeLabel.Text = CDate(DateTime.Now).ToString("MM/dd/yyy")
am making a project were the user can put a specific time in a textbox. the program needs to check the system time and the time in the textboxif they are the same there needs to start an action.

View 2 RepliesI have the following sql select statement in my code:
Code:
sql = "SELECT * "
sql &= "FROM Trn_DC_All "
sql &= " WHERE (Content LIKE '% PAGE%') AND Convert(datetime,Substring(Right(Trn_DC_All.Content,21),2,10),7) >= " &
[code]....
Basically, for the substring in the select satement,the datatype is string. By the way, the strFromDate and strToDate datatype are string also.Actually I would like to select the data from database whereby the Substring(Right(Trn_DC_All.Content,21),2,10) is larger than strFromDate but smaller than strToDate.The dataformat in the database is "Feb 01,09" and the strFromDate,strToDate format is "20/07/2009".What should I change in my select statement so that it can retrieve the data?
I am very surprised to see the output of the function with the given value ,DateTime.Parse("08/19/2011 11:32"). I am using VS2008. Always it returns 08/19/2011 11:32 AM. and if the pass value would be 08/19/2011 14:23 then the output value would be 08/19/2011 02:23 PM. But sometimes it is returning 08/19/2011 11:32 PM for DateTime.Parse("08/19/2011 11:32"). Why?

i've been attempting to update a DateTime Field in a MySQL Table i've created via vb.net. I've made many attempts however i'm still getting the error that i have an error in my SQL Syntax.

I wish to convert my string in format dd/mm/yyyy hh:mm:ss to a DateTime of the same format.
Dim ukCulture As System.Globalization.CultureInfo = New System.Globalization.CultureInfo("en-GB")
Dim myDateTime As DateTime
myDateTime = DateTime.ParseExact("18/05/2010 23:42:10, "dd/MM/yyyy HH:mm:ss", ukCulture)
When I step through this code the variable myDateTime is 05/18/2010 23:42:10 it appears that the dd/mm is the wrong way around and I cant work out how to correct this.
