I am getting an error msg when attempting to update a record from asp.net into a SQL database. The only boolean value being updated is:
cmdAddUser.Parameters.Add(new SqlParameter("@Active", SqlDbType.Bit));
cmdAddUser.Parameters["@Active"].Value =
Convert.ToBoolean(cbAddUserActiveUser.Checked);
The datatype for @Active in the database is "bit".
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:
cmd.Parameters.Add("?yes", OdbcType.Int).Value = (Convert.ToInt32(((RadioButton)GridView2.Rows[i].FindControl("edYes")).Text));
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.
here is my code......where its throwing the error in storeimage.executenonquery() line that Failed to convert parameter type to st
if (newBmp != null)
{
Bitmap convBmp = AddTextToImage(newBmp, text);
Byte[] myimage=ImageToByteArray(convBmp);
//string type = myimage.GetType();

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:

When running our web application the following message appears:

The user_id should be the output after successful insert of record. The stored procedure works well from within the DB and Visual Studio.

I have a problem while creating a web application using LinqTemplate here is the explanation step wise....
1.I have created a database with a table name UserTest with one column name UserId with uniqidentifier datatype2. I have created a classLiberary Project where i have used LinqTemplate of subsonic for code Generation of DAL and created a partial class for UserTest
public partial class TestUser:Classes
{
public int Insert(TestUser user)
[code]...
Now when I Build the project it build successfully and when i run the project it shows
the UserTest.aspx page with a button but when i click on button it must insert the new guid value into the table butit throws an exception
[InvalidCastException: Object must implement IConvertible.]

I am trying to get the UserRole from the logged in user and send it to the database table my code is:
[Code]....
I swear I'm overthinking this as I've tried different combinations to do an insert from Code Behind to my Sql DB.
This is what my table looks like:
[Code]....
My code behind:
[Code]....
I suspect that the problem may be my date. The format that goes from the UI is mm/dd/yyyy.
data.MakeInParam(
"@DOB",SqlDbType.DateTime,10,cust.DateOfBirth),
im new to .net, reponse grt intput for me to get in to it.
I am trying to get the 'userid' of the logged in user using the code below:
"MembershipUser myObject = Membership.GetUser();
String userId = myObject.ProviderUserKey.ToString();"
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 have project in development where string operations like "Hi " + variable + ", welcome to Project" are used at many places (given example is very minor one).
One of the requirement is to convert it to string.format style.
It is very long and tedious job, where I would not like to break earlier working code due to any human error might happen while converting it.
I would like to if any Macro or VS command which I can create to handle it. Just like we mark block of code and do Extract function in Re-factor options.
