Setting Global Variables Within Web Project On Login And Set Expiry Time

Dec 1, 2011

I'm developing a revised version of a system I have been using for years, but with all the advantages of .NET features that were not around when I first made this. It's proving a steep learning curve! So, when a user logs in through my Login.aspx page which simply compares username/password to Database record, the system creates a session variable containing the user's Username and various other things. There are two type of variable which will be common to all elements of this system
User Specific data, Username, Permissions, etc

Setting variables, drawn from a database of pre-set facilities which are setup within the system, some will determine which facilities work, how they work, and some will be dependent upon the User's permission. Obviously, I could set everything within the Session data, but that'd be inefficient wouldn't it? If I were to set these globally available variables in my App_Code, how would I go about setting this up so that, for example, those variables which require a database call, are set for the duration of the Logged-In session and do not require constant Database lookups? Further to that, those variables which are dependent on the session state, would need clearing on each LogOut. I am using VB.NET.

Why Date Shows Up As Date Before Date Trying To Parse?

I could just add a day to this to advance to the original day.

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.

The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.

For what it's worth, the relevent part of the query is:

Select [Date Created] From MyWorksheet

I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL.

Write A Program Which Compares The Difference Between Any Date In The Past And The System Date?

Mar 6, 2009

I'm trying to write a program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date.This is what I've got so far:

Code:
Public Class Form1
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
End Sub

[code]....

That's what it looks like so far. I was wondering how you can automate the top label so it automatically comes up with the date when the program is run.Plus, I need to know how to display the dates difference (how many days have elapsed between the system date and the user's chosen date) in the bottom label.

Checking For Date Overlap Across Multiple Date Range Objects?

Nov 7, 2011

I have several records in a database that have Start and End Dates

09/15/2011 - 09/30/2011
10/15/2011 - 10/22/2011
11/01/2011 - 11/15/2011

When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.

UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:

Here's my code:

Find The Closest Valid Date To One Given As An Invalid Date String?

Aug 18, 2010

So there's this accounting package at my client that spits out text-based reports with invalid dates, like February 31st or September 31st.The reports are formatted with spaces and mono-spaced fonts. The data that gets parsed out are fed into a more formal local SSRS report, and that's about all you need to know.

What I am interested in fixing is the situation where a date is invalid and can't be converted into a DateTime struct. The date format from the report is "MMM-dd-yy" (e.g. "Feb-30-10"). The date strings need to be fixed before being shown in the formal report. I've seen this done two ways in my time as a developer, and I want to come up with a cleverer way of doing it (if there isn't a built-in way I don't know about).The first bad method (I can't believe I'm even showing you!):

Dim month As Integer = <Parse out the month from the bad date string>
Dim day As Integer = <Parse out the day from the bad date string>
Dim year As Integer = <Parse out the year from the bad date string>
Dim validDate As DateTime

enddt is a Date variable and when i convert enddt_2 to a string i get the error as

Conversion from string "17/01/2012" to type 'Date' is not valid.

Let me clarify, if a value in textbox is 17/01/2012 than after parsing the value is changed to 01/17/2012 (my systems Region and Language are dd/MM/yyyy) in enddt_2 and when i try to convert to dd/MM/yyyy format and store into a date variable i get the above error. This error comes only for the dates after 12. i.e a date variable accepts a date in MM/dd/yyyy format.The dates before 12 work fine, i.e for all dates from 1 to 12 there is no error.How can i make enddt store the date in dd/MM/yyyy format.

Date In Datagridview Not Displaying Correct Date Entered?

Apr 12, 2012

I'm working in visual studio 2005 and developing a windows form that has a datagridview on it.

One of the cells is a Calendar Column type (custom made). I pulled the code for it off the internet - it basically allows the user to select the date from a small calendar.

When the date is changed, it gets the correct value and it also saves into the database with the correct value.

The problem is that it doesn't load onto the grid with the correct value. In fact, no matter what date I enter in, it always displays it as 1 day earlier. e.g. If I saved it to the database as 4/19/2012, it displays it as 4/18/2012.

I verified that there's no other column in the query that retrieves the data for the grid that contains the value it's displaying.

Date Time Picker - When Select A Date, The Text Does Not Go Away

Apr 7, 2011

The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.

1: Created a GroupBox
2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True

I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
