View 1 RepliesI am trying to alter a column in an Access database in VB2008 from date to text format using the SQL string as follows "ALTER TABLE receipts ALTER COLUMN Date CHAR(10)"but whether I Use TEXT, CHAR, VARCHAR or STRING, I get a Syntax Error when I run ExecuteNonQuery.
View 2 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:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now
[code].....
I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.
I need to take a string formatted like '010711' (DDMMYY) and put it into format '01-Jul-11'. Ive thought about doing something like string.toArray and then having some conditionals that format from there but am looking for an easier way.
View 5 RepliesThe purpose of my system is to calculate the number of motors (stored in a microsoft access table) that is being sent for repair according to the months. This information will then have to be displayed in a form developed in vb2008.
Below are the coding used:
Public Class FormReportMonthlyOverhaul
Dim connstr As String = "Provider= ..Database.mdb"
Dim rowIndex As Integer = 0
[Code]....
The Start_Date column in the MotorTable db is of 'Text' format. I have a feeling that the there's something wrong with the sql. That is why it returns 0 value.

View 2 RepliesI have a strange issue here. I am working with an access DB that has a field called CompleteDate. Here is my problem; There is a leading 1 in the dates. For instance, today's date format should be 110308 however, in the database the format is 1110308. How can I strip off that leading 1? Can I do this in access or, must I deal with this in my VB program?

View 3 RepliesI am trying to make a filename something like this:
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?
I have a textbox pulling an 'entryDate' field from my table using databinding. The field in the database is set to a 'Short Date', however when I bind that field to a text box and run the app it appends "12:00 AM" to the short date from the Db.
How do I get my databound textbox to simply display the short date which exists in the table?

Not so long ago, I saw somewhere a solution how to check if string is date in yyyyMMdd format (i.e. if it can be converted to date if written in such format). I can't find it anymore but I think is had something to do with DateTime.TryParse method but I can't get it to work. I can get it to work if string is in dd/MM/yyyy format, but dont' know how to make it with yyyyMMdd format. If I'm not mistaken neither of DateTime.TryParse method parameters is for assigning date format...

View 5 Repliesi want to insert a string as date format in mysql table using vb.net.my code is given below.but i always get an error .the string is stored in an array.
mycode

Dim sdfsa As String = Convert.ToDateTime(newarray(i + 17)).ToShortDateString().ToString("yyyy-MM-dd")

I have a string coming into my app that is in the form of:
"Fri Sep 21 07:17:46 2008 GMT" or
"Fri Sep []3 07:17:46 2008 GMT" ([] is a space)
The tricky thing is the space for the date. I currently split the string and grab what I need to make a valid VB date.
Code:
'Receiving a timestamp in the format: Tue Jan 23 19:33:31 2001 GMT
'Split it and grab what we need to make a valid vb date
_element = timeStamp.Split
_dateAndTime = CDate(_element(1) & " " & _element(2) & " " & _element(4) & " " & _element(3))
Return _dateAndTime
I'm running into the problem when the date is a single digit because there is never a 0 on single digit dates. So, when I split the string I get a "" for _element(2) and that's bad. I know workarounds to adapt for this, however, my question is: How to implement the String.Format to manipulate this string as is and make it a valid VB date? How to make VB recognize this string as a valid VB date without a prepending 0 on single dates.
example: 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 15 RepliesI am manipulating xml with lots of date of birth. XMLs are already loaded onto datatable. The format we need is "dd/MM/yyyy" The dates are messy such as "dd-MM-yyyy" or "dd.MM.yyyy" so I am thinking to write a function that will auto correct on a set of predefined separators to a correct format. so I am thinking to do something like this but of course, this won't just work.i cannot use replace to replace an array. If i can just do that, everything would be fine. Hope someone can point out a way around. [code]
