Key Cannot Be Null Parameter Name Key
Apr 2, 2009I am getting an error when I write a value to the database. it tells me "Key cannot be null. Parameter name: key". However the key is an auto-increment value and i'm not even writing to that field. I have verified that there is a value being sent to the SQL. I also created a seperate program that writes the same SQL statement to the db and it writes just fine. I also have other places within the same program that write to the database without any problems.[code]

IDE :: Express Value Cannot Be Null Parameter Name
Dec 30, 2010The problem started when I changed a multiline rich TextBox WordWrap to false..I'm not sure whether I attempted this when the program was running or not. The error list recorded the location as 0, 0.I have attempted to trace the problem by removing the <System. Diagnostics. Debugger StepThrough()> _ attribute in the Sub InitializeComponent located in the Designer module. However, nothing indicates there is a problem within that module.Since this situation occurred, I cannot initiate a ToolStripMenuItem_Click event procedure, located within a pop-up menu, by a right-click of the mouse. I have since attempted to reinitiate the error and the only way I can revisit this error is by changing the WordWrap of the RTB whilst the program runs, but no error is respectively listed or initiated within either the error list or designer module. If the program is running - without an attempt to reinitiate the error - I'm unable to run the pop-up menu.

Output Parameter Defined As Table?

Output Propagates Across Multiple Controls When Using The Same Binding Source
Aug 16, 2011I have SQLdb column elements from one table that are selected from another table. This is achieved through the use of binding a combobox to the selectable entries and applying that entries ID to the initiating table column When I add multiple combo boxes, for multiple columns, the data selected propagates across all the combo boxes I have. They all use the same binding source. It seems to me the only way out of this is to create a bunch of binding sources, essentially one for each control. I have tested this and it appears to work, but is there another, less cluttered way of ensuring that the comboboxes, while bound to the same binding source, are not bound to one another?

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.
Call A Stored Procedure With OUTPUT Parameter?
Jul 31, 2009in my SQL 2005 database I have defined this stored procedure:
CREATE PROCEDURE [dbo].[CheckOrders] (
@PK_Customer uniqueidentifier,
@Amount bigint OUTPUT)
[code]....
When I check the value of nAmount it stil contains the original value -1 the output value didn't return from the stored procedure although the number of records updated is 0 or more. The procedure was checked, it works and there are records updated and the value of @Amount is SET to a value 0 or more. I just don't get the values back. eventough the parameter @Amount is defined as OUTPUT. I also tried with outParam.Direction = Data.ParameterDirection.InputOutput instead of outParam.Direction = Data.ParameterDirection.Output . Same result. How do I get the value back from the stored procedure?
