Easier way to get data from the CSV file and substitute data from other tables in columns with foreign key

Anyone can help? All day I can not understand why I get an error.
Error is:
SqlParameter with ParameterName '#FKTO' is not included in SqlParameterCollection
Maybe there is an easier way to get data from the CSV file and substitute data from other tables in columns with foreign key.

why i got the error "Input string was not in a correct format"

I am inserting data from datagridview into database , I debug my code and found the error Input string was not in a correct format. in the following line
Convert.ToInt32(dgvResult.Rows[i].Cells[9].Value.ToString())
this column is an integer column and when i replaced this line with integer value for example number 3 insert completed without errors , and the other integer columns also inserted same way without any error
this is my code :
if (checkApproveResult.Checked == false && chkupdateApproved.Checked == false)
{
for (int i = 0; i < dgvResult.Rows.Count; i++)
{
result.UPDATE_LAB_RESULTS(Convert.ToInt32(txtOrder.Text),

}
And the code for ADD_LAB_RESULT_UPDATES was :

DAL.ExecuteCommand("ADD_LAB_RESULTS_UPDATES", param);
DAL.close();
}
the error with parameter 14 machine_id
also the table in the database machine_id int.
What is the error ?
More information I have first if statement (update statement)
result. UPDATE_LAB_RESULTS includes same parameter machine_id and its working and inserting without errors.
Second if statement (insert statement) and show the error with machine_id parameter.

You have to check the following :
1- check the parameter list variables types (string , int , ...) and compare it with your procedure you will find one variable type different in the stored procedure integer and in the parameter list string.

Specified cast is not valid issue

My code checks for changes in the database and then sends an update via a web service to the client.
I had the part sending the message to the client working fine because making the calls to check for changes in the database. Now that I have added the portion checking database changes I am getting the following error.
When Debugging my code the error points at the exception at the very bottom of the code so I have no idea where the error is coming from and no way of fixing it.
Any advise would be greatly appreciated

You're hiding your real exception stack trace by catching the exception and throwing it again like you're doing;
try {
...
}
catch(Exception ex) // catch all exceptions
{
throw ex; // throw the same exception, removing the old stack trace
}
Either you should just remove the whole try/catch, or change to;
try {
...
}
catch(Exception ex) // catch all exceptions
{
throw; // throw the last caught exception, keeping the stack trace
}
and you will suddenly be able to see the exact location of your original exception. I'm sure you will find your error right away.

In my case, getting this error message, Oracle turned out to be returning an irrational number.
My code was throwing the "Specified cast is not valid" exception at adapter.Fill(ds);.NET was not interpreting the returned number correctly with the code I had been using. The addition of the line adapter.ReturnProviderSpecificTypes = true; Made it possible for .NET to interpret the number, rounded to the Nth decimal (last digit rounded up from 3 to 4 for some reason...): 2.25000000000000333333333333333333333334
private static DataSet dataset_test(string sql)
{
DataSet ds = new DataSet();
using (OracleConnection objConn = new OracleConnection(connectionstring))
{
OracleCommand objCmd = new OracleCommand();
objCmd.Connection = objConn;
objCmd.CommandText = sql;
objCmd.CommandType = CommandType.Text;
try
{
objConn.Open();
OracleDataAdapter adapter = new OracleDataAdapter(objCmd);
adapter.ReturnProviderSpecificTypes = true;
adapter.Fill(ds);
}
catch (Exception)
{
throw;
}
objConn.Close();
return ds;
}
}

One thing to try: Set a breakpoint right at the start of the try-catch block, on the connStr = line, and step through the code line by line, progressing over method calls. In this way you can quickly track down which part of the code is throwing the error, and then home in on that point to look for the specific problem. (You will also be able to read the original exception and innerexception messages prior to the rethrow.)
Given the title of your question, so the assumption that the error you are having is a casting exception, the first place I would check would be in your database data retrieval code. You are using sdr.GetInt32(0) for instance, this would throw that sort of error if column 0 couldn't be converted to an integer.
Hope this helps. If you are able to track down more information, post it and we'll see if we can give more specific advice.

How to implement Edit Feature in asp.net application?

Below 2 links give the preview of my sample application.
http://img812.imageshack.us/i/image1adl.jpg/ : shows mine sample application. All fields are self explanatory (if query, let me know)
http://img834.imageshack.us/i/image2vc.jpg/ : shows, when clicked the "Edit" button from the grid, the timings are shown correctly but the order gets disturbed. (See 7:00 coming on the top and then the timings list are seen).
My Questions
How to correct the timings problem? (Link # 2)
Code for "Edit" is below

Please help!

Where do you define Bool/Bolean IsEdit? I think its value is reset on page postback, that's why it is always false and the record is being inserted. I would suggest you to use a hidden field to track this and set its value there and check the value upon insert/updating. Finally it will be something like...
if (ds.Tables[0].Rows.Count > 0)
{
//your code
hiddenField.Value = "true"; // you can set default value to false
}
and then after
if (hiddenField.Value == "false")
{
cmd.CommandText = "Insert into Images(FileName,FileContent,IsDeleted,IsActive,StartTime,EndTime) values (#img_name, #img_content,#IsDeleted,#IsActive,#StartTime,#EndTime)";
}
else
{
cmd.CommandText = "Update Images set FileName=#img_name, FileContent=#img_content, IsDeleted= #IsDeleted,IsActive= #IsActive, StartTime=#StartTime,EndTime=#EndTime";
}

Insert Query in C# using Parameters

Am trying to insert several columns into my database using the following insert query from C# but it throws the exception somehow somewhere and my guess is there are no values provided for insertion. i just want to confirm that and find out how i can fix the insert statement. i have a picture below that displays what is passed into the parameters at runtime. i used a break point to get this info.
need your expertise at this one...thanks

the exception is as follows
$exception {"The parameterized query '(#CaseID int,#ExhibitType ntext,#ExhibitImage image,#DateReceive' expects the parameter '#SuspectID', which was not supplied."} System.Exception {System.Data.SqlClient.SqlException}

If you want to pass in NULL for your database / parameter type, you need to use DBNull.Value like this:
SqlParameter param9 = new SqlParameter("#ManagerID", SqlDbType.NChar, 10);
param9.Value = DBNull.Value;
command.Parameters.Add(param9);
Do this wherever you're setting something to null right now, and I'm pretty sure it'll work just fine. Everything is looking okay.

You can do this much easier, try it as such:
if (Page.IsValid)

DateTime exhibitDate = DateTime.Now;
int caseid = Convert.ToInt32(CaseIDDropDownList.SelectedItem.Text);
string exhibittype = exhibitTypeTextBox.Text.ToString();

try
{
SqlConnection connections = new SqlConnection(strConn);
SqlCommand command = new SqlCommand("INSERT INTO Exhibits (CaseID, ExhibitType, ExhibitImage, DateReceived, StoredLocation, InvestigationStatus, OfficerID, SuspectID, InvestigatorID, ManagerID, AdminID ) VALUES (#CaseID, #ExhibitType, #ExhibitImage, #DateReceived, #StoredLocation, #InvestigationStatus, #OfficerID, #SuspectID, #InvestigatorID, #ManagerID, #AdminID)", connections);
command.Parameters.AddWithValue("#CaseID", caseid);
//and so on for your 10 parameters
connections.Open();
int numRowsAffected = command.ExecuteNonQuery();
connections.Close();
if (numRowsAffected != 0)
{
Response.Write("<BR>Rows Inserted successfully");
CaseIDDropDownList.ClearSelection();
exhibitTypeTextBox.Text = null;
storedLocationTextBox.Text = null;
DropDownList1.ClearSelection();
}
else
{
Response.Write("<BR>An error occurred uploading the image");
}
}
catch (Exception ex)
{
string script = "<script>alert('" + ex.Message + "');</script>";
}
}
I'm not sure if this will actually fix what is happening without knowing the exact exception. If you could provide the actual exception that would help a lot.
