I have a project that I developed in VS2005 and that has been put into VSS. I am trying to "get" it on a new machine and convert it to VS2008 because that is what is installed on the new machine. I am having problems with it that I think originate in its working folder. So my basic question is, when you try to work with a solution that's in VSS should you maintain the same folder structure that it had when it was originally checked in? I'm not particularly happy with its original structure because it goes on and on seven levels deep, and I wanted to just cut it down to C:ProjectsResNew, but if that's what it takes to get it to work, I'll do it.
STDNo nvarchar(6) //student number primary CID nvarchar(7) //course ID primary DNo int //Department Number primary H1 int allow null // Home work 1 H2 int allow null H3 int allow null H4 int allow null H5 int allow null Q1 int allow null //Quize 1 Q2 int allow null Q3 int allow null Q4 int allow null Q5 int allow null HE1 int allow null HE2 int allow null FExam int allow null // Final Exam
and stored procedure like this:
ALTER procedure [dbo].[AddMonthlyMarks] ( @STDNo nvarchar(6), @CID nvarchar(7), @Dno int =isnull, @H1 int, @H2 int,..........................

I have a class with properties for stuff like FileNumber, OpenedDate, ClosedDate etc.When I Initialise the class I set the datetime variables to Date.MinValue.Then when I populate my textboxes I check if the value of the date variables are Date.Minvalue and I set the textbox text to an empty string.
Code: If(File.OpenedDate = Date.MinValue, String.Empty, File.OpenedDate.ToString("yyyy/MM/dd")) However whe I try to save the data to my sql server db I get a datetime out of range error. What is the correct way to handle these null values in my date columns?
we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?

The application needs to convert foreign characters to an American keyboard representation. It has always done so, but the customer recently added a new list of Polish characters. I have found all the documentation on the Internet, except for this. Why the "friendly" column doesn't have values for these characters?

I have numerous web sites created over the years. Some were created using FrontPage with aspx pages added that were created in VS 2003 or VS 2005. Others were web sites that were actually created with VS 2005 or 2008. All these older sites reside in the C:Inetpubwwwroot folder of my present development computer, with only the .sln and the .suo files residing in the project folder. All of the sites have counterparts on the Internet.I am about to build a new computer and would prefer to only install VS 2010 on it. When Previously building new computers, I installed VS 2005 and VS 2008 so that I could administer
on VWD 2005 this code works fine, but on 2008 it says I haven't created an instance of the object. I want to convert the object connString (a connection string) into a string.

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.
I have a stored procedure to insert data into Table B, but when I tried to insert a null value into column ID of table B, this error came up:
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.
I am guessing adding nothing to the null value column is the problem, but i don't know how to fix it... The INSERT statement conflicted with the FOREIGN KEY constraint "FK_tableB_tableA". The conflict occurred in database "database name", table "table A", column 'ID'.

I have a problem with a SessionVariable. I will explain what is happening:
1. From the default.aspx I send Session["LoginByAdmin"] = "Dummy"; and then redirect to this page where I have the code below. So the Page_Load sees that this Session["LoginByAdmin"] != null and enter this page. This works fine !
2. In the Page_Load, I later fill a ListBox1 with foldernames.
3. With Button1_Click1, I will now delete the choosen Folder in the ListBox1 wich works fine the first time and the ListBox updates the new existing folders in the ListBox. (I have wrapped this inside an updatepanel)
The problems comes now when I try to delete a choosen folder in the ListBox1 the second time in a row. When I select a Folder in the ListBox1 and now Press Button1, I will be redirected to "Default.aspx". This meens that this code is running: (That meens that Session["LoginByAdmin"] == null and I have not set this to null anywhere. This is my big question how this variable can be = null here?
if (Session["LoginByAdmin"] == null) Response.Redirect("Default.aspx"); break;
