i'm having a hard time figuring the way on converting my string into an integer number.In my form I have a textbox control from which I get the selected date as string, using the substring method I divide it to month, day and year.The problem is that I cannot, for example, convert the following "12" into the actual integer number twelve. I tried using Int32.Parse or Convert.ToInt32 but still couldn't solve it.Here's my code behind for better comprehension (this doesn't do the trick):

And within the BLL is where I am trying to convert it before it gets inserted into the database.
I have a third party tool that creates an img tag through code using HtmlTextWriter's RenderBeginTag, RenderEndTag & AddAttribute methods. I want to get the resulting HTML into a string.
I tried the reflection method mentioned here but I get a error "Unable to cast object of type 'System.Web.HttpWriter' to type 'System.IO.StringWriter". The InnerWriter type of the HtmlTextWriter is of type HttpWriter.
I have an AJAX service where I'm pulling HTML content. I want to Response.Write() it to the browser as a string. I can't figure out how to do it so it remains a string like this rather than formatting the HTML:

<Exception> Conversion failed when converting datetime from character string.
</Exception> Puzzled why the query works fine but .net gives me an exception? does anyone know how to solve this?
The part of my query that does this conversion is:

as part of a project I am working on, I need to output the alphabetical 'name' of the number. This is better illustrated with an example.960Nine Hundred and SixtySo it'd convert '960' to 'Nine Hundred and Sixty'. Is there an easy way to do this in C#.NET? Also, if so, how easy would it be to apply the same function to a decimal number? I'm assuming if I can figure out how to convert a integer as above, I can just split the decimal number... so I'd have something like this 960.23 Nine Hundred and Sixty (units) andTwenty Three (units)

I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound If e.Row.RowType = DataControlRowType.DataRow Then For i As Integer = 0 To e.Row.Cells.Count - 1 Dim cellDate As Date If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then e.Row.Cells(i).Text = String.Format("{0:d}", cellDate) End If Next End If End Sub
how I can get around the following error with the following code?
[Code]....
Error: Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. As you can probably tell, the datatypes are: m.UserId = uniqueidentifier l.System_User_ID = varchar(256) I was hoping the casting of one to the other would solve the issue, but it doesn't. How can I re-code this? I see from other forums it would probably be best to set all these fields to uniqueidentifier, but would prefer not to at this stage as it will involve changing quite a bit throughout the whole site!
