im creating a simple module to get data from access with date as filter.

now, i want user to enter date(which is in string) and get data from access.

i tried parse, exactparse but each get time with date.

The DateTime object will always contain a time element. If you use myDate.Date it will normalise the time element to be midnight.

At the risk of repeating myself: The DateTime object will always contain a time element.

string str = "04-13-2009";
DateTime dt = DateTime.ParseExact(str, "MM-dd-yyyy", System.Globalization.CultureInfo.InvariantCulture);

// Show the date only.
Console.WriteLine(dt.ToString("MM-dd-YYYY"));

Exactly. But the OPs complaint is that the DateTime object still contains time.

You seem to want the moon on a plate.

You want a string parsed to a DateTime, you do not want the time element. Your solution, and the solution everyone else uses, is to simply ignore the time part. If you are doing date calculations then normalise it by setting the time part to midnight (e.g. myDateTimeObject = myDateTimeObject.Date)

How can a query compare my date with that of ms access date???

Use a parameterised query.

With Access you use a question mark to denote where a parameter goes. Then you add the values in the Parameters collection in the same order in which the question marks appear in your query.

cmd.CommandText = "SELECT * FROM MyTable WHERE SomeDateColumn = ?";
cmd.Parameters.AddWithValue("?", myDateTimeObject);

well thanks Colin Angus Mackay and HO for your friendly support.

Things work with the

DateTime dt = DateTime.ParseExact(textBox1.Text.ToString(), "MM/dd/yyyy", System.Globalization.CultureInfo.InvariantCulture);

Thanks a ton

Will come again with new problem...

c ya again

Hi,

Why dont you try out using regular expressions and return only the date... I think that might solve your problem...

normally i run application1 by opening the solution and pressing F5.

Is it possible to create a dummy application2, then include application1's DLL
by adding reference to it and execute application1 from dummy application2?
