View 10 Replieshow I can ensure that conversion of a date to a string and a string to a date will give me the same date format.
For example:
Code:

However, I also need to write the date in string format to an Access database using INSERT INTO. However, when the code is ran, I get a "syntax error (missing operator)". Code is below. Can someone help please? I have tried all I know to do.(Please disregard the additional values in INSERT TO, I have verified they are working properly)

I 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
Me.dataGridView1.Columns("Date").DefaultCellStyle.Format = "d"It didnot have any impact.
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.

As you can see below in the code the " & tblName & " will work fine but instead of using the BankName (which the user cannot change because it is in the code) I would like to do the same as I did with the Table name and use a variable that gets its name from an excel spreadsheet rather that an actual name hard coded in a VBA module. I would like the variable field name entered in the Excel Spreadsheet by the user just like the table name is filled in by the user. The problem is getting the ADO SQL string ( cmd.CommandText = "ALTER TABLE " & tblName & " Add Column BankName Char(25)" ) to recognize that the value in the Variable " & fldName & " is the field name to be used.
Sub AddFieldToAccess()
Dim cnn As ADODB.Connection
Dim cmd As ADODB.Command
[code]....
'If I do this I end up with a field named BankName what I need is the name in the variable " & fldName & "
cmd.CommandText = "ALTER TABLE " & tblName & " Add Column BankName Char(25)"
cmd.Execute , , adCmdText
Set cmd = Nothing

dim Test as string = "name_" + now.toshortdatestring() + ".pdf"
The datestring is like MM/DD/YYYY, which is a particularly bad filename (who want slashes in their file names??)Is there a way to format the date string differently (ie MM-DD-YYYY)?What I was trying to do is tag the file with a date so I could tell when the last time that file was generated, and also keep multiple copies around for archive purposes. Maybe there is a better way and then I dont even need this differently formatted string?
