Yeah, I could. But I want the framework to tell me what it is.
I think hacking into the file, while valid, isn't the solution I was looking for.
Thanks for helping tho.

If the file can be loaded into a Bitmap object, then you can use this test to see if it is a JPEG/JPG type image:
if( someBitmap.RawFormat.Guid == System.Drawing.Imaging.ImageFormat.Jpeg.Guid ) {}

I have a popup datepicker in my application which is ran using javascript. When I run my application from my pc it works fine but wehen I run my app from a server it causes a problem. The problem is that if I select a date like today 02/05/2006 this will go into the field on my app, when I submit the form in the date goes into the datbase field as 05/02/2006 which is the wrong way round. I am using GMT as the time zone regional setting. The field in the database is datetime.
Anyone any ideas why this is happening?

Simple. Its getting converted to the american format of storing dates. The solution is very simple. Just before writing to the Database, make sure that you pass it as a DateTime variable using some syntax like,
DateTime dt=DateTime.Parse(dtPicker.SelectedDate.ToString("dd-MM-yyyy");
Hence even if a value such as 02/05/2006 is stored in the database as 05/02/2006, while retrieving it will still get you 02/05/2006 once you get it with the same format as dt.ToString("dd-MM-yyyy");

It is being passed into the stored procedure in the British format, so I think I need to do the conversion you are proposing in the datbase itself. Can I use your code "DateTime dt=DateTime.Parse(dtPicker.SelectedDate.ToString("dd-MM-yyyy");" in the stored procedure?
I need it stored in the dataase in the correct format as I run some other queries based on the dates i.e. select all between two dates.

The answer is that using dd/mm/yyyy and/or mm/dd/yyyy is ambiguous - it looks like your webserver is configured to use UK date format, but that your sql server instance has been installed to use US format.
I have always gotten around this by using an unambiguaous format. So either:
1) 2 May 2006
2) 2006/05/02
Both are unambiguous and will never cause the problems you specify.

Well...If you are confident that its being passed into the Stored proc in British Format, then while retriveing it just use the ToString() method as ToString("dd-MM-yyyy"). It should get you the date in british format.
By the way, the code dt=DateTime.Parse(dtPicker.SelectedDate.ToString("dd-MM-yyyy");
WILL NOT work inside the Stored Proc as this is not a T-SQL statement. It works only inside .NET.

Hello,
I want to display a report like the one given below in ASP.NET1.1 using any of the web server contrls such as Repeater, DataView, DataList etc. This report is a little different from a table like report in that it has section headings such as Status:Enabled, Status: Disabled etc. My stored proc returns all the data at once sorted using the status code (2:Enabled, 1:Disabled, 0:Temporary etc). Any help is appreciated. I guess the DataGrid is not very usefull if you want your tables to be formatted...like in this case I want a sections-based report. Many thanks

I am adding two cotrols to a panel. Currently, the controls are appearing next to each other. I want the second control to appear at the bottom of the first one. For instance, currently, they appear as: 'Label' 'Checkbox'.
However, I want them to appear as:
'Label'
'Checkbox'
How do I do this?
I have this code:
Panel panel = new Panel();
Label pr = new Label();
pr.Text = "some text";
panel.Controls.Add(pr);
CheckBox BasketCheckBox = new CheckBox();
panel.Controls.Add(BasketCheckBox);
Kind regards

What I need is this:
panel.Controls.Add(new LiteralControl("
"));
before adding the checkbox

You could 'save' the drop down list data in a javascript array on the page and then implement an onclick event for the drop down list that would call to a javascript function to create and populate your dropdown list.

Is the app configured as an application in IIS? go to IIS manager, expand the website to the directory containing your app, right click, go to properties and there should be an entry in the application settings/starting point. If there isn't then click the 'create' button beside it.

A DataSet is used to hold DataTable objects. Usually a DataSet contains one DataTable that is fetched from a database.
A DataView is used to filter and sort data from a DataTable.
A Repeater is a designer control that takes a data source (for an example a DataTable or a DataView) and repeats it's contents for every record in the source.
