how I can get around the following error with the following 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!
I am trying to retrieve xml from a small function in my .cshtml page. Its throwing me an error. This however, runs fine in a console/form environment. It takes 3 parameters and 1 exception.
[Code]....
Within my GetXML function it simply applies the parameters to a store procedure. The store procedure returns me my object. From there I can do all the fun stuff in .cshtml. When I manually enter the values from within SQL Management Studio, I do in fact get the right result. Again, when I create a Window Form application - I too get the right result! When it comes down to .cshtml or .aspx pages - I get the conversion failed. I have already tried casting the store procedure uniqueidentifier parameter and it still gave me that error.
I have a database call that is comparing UserID column of two tables. The UserID is a uniqueidentifier. The page errors on the r.read() line with Conversion failed when converting from a character string to uniqueidentifier. I'm not sure how to code this to avoid the error.
cmd.CommandText = "SELECT a.CenterName FROM Centers a INNER JOIN UserInfo u ON a.CenterID = u.CenterID WHERE u.UserID='{ + SessionManager.UserID + }'";
r = cmd.ExecuteReader();
r.Read();

FROM aspnet_Users INNER JOIN
aspnet_starterkits_Projects ON aspnet_Users.UserName = aspnet_starterkits_Projects.ProjectManagerId
When I run this i get an error message: "Conversion failed when converting from a character string to uniqueidentifier" Is there anyway around this? Or a different select statement etc?

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):

[Code]....
But it is still giving a "String was not a recognized as a valid DateTime." In the full context, I have a webpage with a formview on it and within the formview is a TextBox control that is taking a user input such as "1999" then an ObjectDataSource picks it up and runs it through a BLL. And within the BLL is where I am trying to convert it before it gets inserted into the database.

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:
<div id="global_nav">
<ul>
<li class="left"><a class="sub practice" href="/practice-time"><span>Practice Time</span>.
I've tried using HTTPUtility.HTMLDecode(string), but that doesn't appear to do anything.
I have a query that converts my string value I have stored in the database (nchar(8)). I have a stored procedure that gets the value and converts to date and when I run the select part of my stored proc to test it it successfully returns the mm/dd/yy format that I want: ex: 02/28/2010 However when I call this stored proc from my program I am getting an exception:
<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:

View 5 Repliesas 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)
