and later using it as a parameter to the stored procedure.
The logic here is, the user should login first in order to retrieve his/her album. when the user is logged in, im retrieving the 'userid' and using it as parameter to load the corresponding album from the database.
when i login and open the albumpage, im end up with this exception:
"Failed to convert parameter value from a String to a Guid".
What could be the reason and how can i avoid this exception.
by the way im using the aspnet_Users table's userid field.

I'm using a GridView control to edit data in a MySQL database.
I've created the C# code behind but I'm having trouble pulling back the parameter from a radiobutton control to populate an Int32 field in the database. I'm getting "Input string not in correct format"This is the particular bit (amongst a host of others of the same type) that is causing the problem:
I have written a code to insert emp details into database and i am also inserting local date(i,e system date) into to the table to know/have an idea at what date the employee inserted details. I have set date format add/MM/yyyy and its working well in my local system, but after uploading the site into server (the server is shared server) iam getting error and the error message is Failed to convert parameter value from a String to a DateTime.
Surprisingly, it is working well in server when i chaged the date format to MM/dd/yyyy, but now its not working in my local system and getting the same error.
I am not sure where my app is failing but most probably this is where it is failing.. I think lblExpID.Text is the culprit. Here's the relvant part of my code:
Dim lblExpID As Label For Each item In LSGrid.Rows lblExpID = item.FindControl("lblID") If txtExpGenFund.Text <> "" Then sqlArray(i) = ExpDetailsID & "," & (lblExpID.Text) & "," & MunID & "," & _ Val(txtExpGenFund.Text) & "," & Val(txtExpDetSpecialRevenue.Text) & "," & _ Val(txtExpDetCapitalProjects.Text) & "," & expTotal & "," & reportingYear & "," & "Test Comments" & "," & UserID End If
Can u help me identify why i am getting this error looking at the sp below:
PROCEDURE [dbo].[uspEXPENDITURE_DETAILS] ( @ExpDetailsID int=0 output, @ExpDet_ExpID int, @ExpDet_Municipality_ID nvarchar(50), @ExpDetGeneralFund money, @ExpDetSpecialRevenue money, @ExpDetCapitalProjects money, @ExpDetTotal money, @Exp_Reporting_Year varchar(10), @ExpComments varchar(max), @Contact_ID int ) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements.

When running our web application the following message appears:
Failed to convert parameter value string to decimal. We believe that the problem might be with the sequence which generates the user_id. The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio. Our DB version: 11gR1 on Windows.The web form has a button event with this c#-code:

I am attempting to use SqlBulkCopy to import data from an XML document. I receive the following error when executing WriteToServer: Invalid cast from 'System.String' to 'System.Guid'
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.
Using the following quires, for select and Update,. Select qry is working fine ,but update qry throws 'conversion failed when converting datetime from character string' .
select * from table1 where CreatedDt >= convert(datetime,'12/23/2009',101) and createdDt < dateadd(d,1,convert(datetime,'12/23/2009',101))
Update Table1 set status = 'y' where CreatedDt>= convert(datetime,'12/23/2009',101) and CreatedDt < dateadd(d,1,convert(datetime,'12/23/2009',101)

q="select convert(char(8),datecol1,112) from tblone where datecol2 is null"
is what I use for my query string for sqlcommand(). I'm getting the error "a field or property datecol1 could not be found in the datasource". Without the convert, the query is ok.
the problem is when I use debugging mode, I mean using with visual studio, it's going fine. But when I call from IIS there has a error.. Unterminated string constant. I know where is the problem
I'm having a asp.net listbox on the front end webform with multiple selection, after user selecting multiple items, i'm capturing the DataKeyValue of listbox(which is amenity_id of bigint) and looping all the selected items to a string with comma sepearated values.

I'm geting this error while inserting.. i know that my data type is of bigint and i'm trying to insert string type. i need to convert the string type to INT type and insert data. below are my stored procs:
