First off a great piece of code [URL] you saved me soooo much time. I am a somewhat newbee to VB2010 and was wondering how would i go about setting lets say setting column(4) to a date format so that i can get it to sort in the correct order.
View 8 Repliesexample: inside regional date format setting i set "Short date format dd/MMM/yyyy" and inside vb.net program i set "strSQL = strSQL & ",'" & Date(Date.Now.ToString("dd/MM/yyyy")) & "'" ----> working fine. if user changed the regional date format setting to other format like "mm/dd/yy" facing problem during saving record into sql table. error date conversion. It's possible to avoid using computer regional date format from vb.net? or have any other way...
View 2 RepliesI have a DGV that is getting data from a sql db. The dates in this db are stored as doubles ie 40025.708681
How do I format this column as Date/Time?
I tried but this doesn't seem to work.
how to do this? DGV1.Columns("HostDate").DefaultCellStyle.Format = "d"
I need to sort a datatable. I do it with linq this an example
Dim query = From c In dt.AsEnumerable _
Order By c.Field(Of DateTime?)("LastPurchaseDate"), _
c.Field(Of String)("LastName") Descending
Dim dv As DataView = query.AsDataView
But my problem is that i need to sort the fields not by passing the name of the column but the index of that.
I want to sort my datatable column(0) alphabetically, but cant seem to find a way to do it. Just to give you an idea:

I am creating a datatable and then adding a column to it which is filled with data from existing column and parsed into correct format DateSold is my existing column from my datafile and I create NewDateSold by adding the column to the existing table and then parsing the information in date format.
This is added to a binding source which then is used to populate a combobox I want to be able to sort the combo box by NewDateSold Desc I was able to this on the original column by simply using the "order By" in my query, it seems now that I added new column it is no longer sorted? I am finding different solution such as using dataview and wish to know the best way to do this
I got a gridview which auto generates columns. One of the columns is a date field.Somehow, i cant sort the date field. It's being interpreted as a string.The data comes out a database. The datatype there is set on datetime.his is the code in the aspx file:
<asp:BoundField DataField="date" HeaderText="date" SortExpression="date" DataFormatString="{0:dd/MM/yyyy}" HtmlEncode="false"/>
[code].....
So I made a little program, and when I run it on my computer the Date format displays as DD/MM/YYYY, but when I run it on some other computers it displays as MM/DD/YYYY. Is there anyway to set the default incoming Date format? Or do I just have to be very careful about how I get/set parts of dates?

I have a column with dates on it and I'm trying to sort it according to that.[code]I tried to use this but it only sorts by the first two digits, dd, and not with the full date.
View 7 RepliesI have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview. I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows). If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that.

View 16 RepliesI have an SQL Database which has some end dates. I have used this little statement to make sure that the dates come out of the database in the right format
Execute("Set dateformat dmy")
And I use the below statement to enter the data in to a datatable and, with the above command, when I go to look at the data in datatable visualiser the dates seem to be in the correct dd/MM/yyyy format
"SELECT CID, expdate FROM Traineecerts WHERE iscurrent = 1"
Now when i try d1 = row("expdate") the format changes to the american MM/dd/yyyy format
Please note d1 refers to a variable with the type of date. Even if I format the dates after using d1 = format(row("expdate"),"dd/MM/yyyy") they don't change unless I make d1 a string. Is this normal?

View 1 RepliesI have a datagridview populated using a csv file. I have a column named Date. The csv file has mixup of different date formats. So I need the date column in datagridview to be in standard "MM-dd-yyyy" format. I used below code

So I used the below shown code Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "MM-dd-yyyy"Still no effect.
I have a .aspx file with a datagrid in it[code]...
The .aspx.vb file associated with it fills it in with a datagrid object.[code]...
That all works fine. However I want to format one of the columns with a particular date format. Is there a way of doing that in the vb code? I know I can do it in the .aspx by specifing AutoGenerateColumns="False" and then explicitly defining the columns, but I want to do it in the code as it's more future proof for my application.

View 8 RepliesI have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)
now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings
I'm having a problem declaring a variable and setting it correctly.
