Web Forms :: Calculate And Display DateTime In TextBox Based On Date Populated From Database
Oct 7, 2012
in my asp.net_vb web there is a text box (textbox1) in which a date is dispalyed from database (eg 21-Mar-2012) in another text box (textbox2) i want to display
if the date is less than 30 Jun then the textbox2 should display 1 Jul+the year of textbox1
if the textbox1 date is greater than 30 Jun the text box2 should display 1 Dec + the year of textbox1
I am using Calendar to display Date in Textbox. my Problem is that it works Ok in localhost but when I had uploaded the same, error come "Unable to convert String to datetime".
if I google it I get things like "you could try..." or "that doesn't work if...", etc. and I want some tried and true way. So, have you written any age-calculation routines and found they actually work when put to the test (that would be, when they go live ) or simply found one on the Internet?
I tried googling "vbforums .net calculate age" and I got some VB6 code. I am thinking there might be something more sophisticated in .NET.
I tried searching "calculate age" in the advanced search here, and got hits like "calculate tax" and "calculate discount" so it's not recognizing my combined keyword string.
have two text box on which I give two date input by using rapid application development datepicker textbox. I have another text box on which I wanna show the duration of those two text box date. I want to calculate total days of those to date.
i have created a table with column like date (datetime), employeename (varchar) and their designation (varchar).. am using sql server 2005 and vb.net
I want to display this information in gridview.. i also displayed the inforamtion, but what the problem is the display of date is 4/2/2010 12:00:00 AM.. i need to display only the date in the gridview as 4/2/2010 under the date column .
I have 3 Textboxes in my Web page. When user key in value in these 3 textboxes,their result should show on a "Label"
1) Gross Amount 2) Taxable Amount 3) Tax Amount
I have to write a Stored Procedure for calculating the value of above textboxes.
Condition is:
If Gross Amount is > or < 0.00, then Taxable and Tax amount should calculate based on below formula: @TaxableAmt = @GrossAmt / @Rate @TaxAmt = @GrossAmt - @TaxableAmt
but If Taxable Aount is > or < 0.00, then Gross and Tax amount should calculate based on below forumla:
and for "Tax Amount" I have 2 different conditions:
If Tax Amount is = 0.00, then Taxable and Gross amount should calculate based on below formula: @TaxableAmt = @TaxAmt / (@Rate-1) @GrossAmt = @TaxAmt + @TaxableAmt
but If Tax Amout is <> 0.00, then whatever the value of Tax Amount is, it should key-in/show as it is.
i.e., @TaxAmt = @TaxAmt
For this requirement, I wrote below SP:
ALTER PROCEDURE [Invoice].[usp_tbl_TaxCode_Update] -- Add the parameters for the stored procedure here @TaxCodeID nvarchar(50) , @GrossAmt decimal(18, 2), @TaxableAmt decimal(18, 2), @TaxAmt decimal(18, 2)
I am saving users information in Sql Server 2005 Database. The problems are:1.

The format of DateofBirth column is incorrect it should be 1/Jan/1990 inspite of2013-01-01 00:00:00.000. The data type is Datetime

I'd like to use the jquery calendar control to populate a date into an asp.net textbox.

My Application hosted at server in time zone which differs from mine. All date in database is not correct for my time zone. How can I set my time zone for Application or how I can convert date to my time zone on output
I am trying to insert "Date" and "Time" in database table (both are separate columns) using below code:
string query = "Insert into tempTable(List_Id, Date, Time) VALUES('" + lblId.Text + "', @Date, @Time)"; SqlCommand cmd = new SqlCommand(query, connection); connection.Open(); TimeSpan time = new TimeSpan(); time.ToString(); cmd.Parameters.AddWithValue("@Date", Convert.ToDateTime(DateTime.Now.ToShortDateString())); cmd.Parameters.AddWithValue("@Time", Convert.ToDateTime(DateTime.Now.ToString("HH:mm:ss"))); cmd.ExecuteNonQuery(); connection.Close();
Above record is inserted in DB like below:In Date column: 12/29/2014 12:00:00 AMIn Time column:12/29/2014 5:30:46 PMDatatype for "Date" and "Time" column is "datetime"I want that: as I save the Date and Time in DB table, it should display same date and same time what is saved in DB table not current date and time.I tried below code to fetch saved records from table, after inserting Date and Time in DB:
string query2 = "Select Date, Time where Id='" + itemId + "'"; SqlCommand cmd2 = new SqlCommand(query2, connection); connection.Open(); SqlDataAdapter da = new SqlDataAdapter(query2, connection); DataTable dt = new DataTable(); da.Fill(dt); lblDate.Text = DateTime.Parse(dt.Rows[0][0].ToString()).ToString("dd-MM-yyyy"); lblTime.Text = DateTime.Parse(dt.Rows[0][1].ToString()).ToString("HH:MM tt");
But currently it is giving me below output : Date:29-12-2014Time:18:04 PM (current time)..
Why its showing current date time in place of saved record ??
I am having trouble formatting the date on a textbox I get the error above if I don't enter the date in MM/DD/YY format in the textbox.

Does anyone have any ideas on how I would do any of this.
