Null Reference Exception In Line Checking For Null?
Dec 15, 2011I have a fairly simple piece of code:
Private _PurchaseDelivery as PurchaseDelivery
Protected Overrides Sub InsertItem(ByVal index As Integer, ByVal item As PurchaseDeliveryItem)
[Code]....
Which is inside a class which overrides a custom list base. The code is occassionaly throwing an unhandled exception, System.NullReferenceException, on this line when used in production:
If _PurchaseDelivery IsNot Nothing AndAlso _PurchaseDelivery.DefaultSKUBinID.HasValue Then
DeafultSKUBinID is declared as an Integer? (Nullable Int) in the PurchaseDelivery class. I cannot see what might be causing this error, why would this be returning an error?

SQL Exception (adding A Null Value To A Non-null Column)
Aug 12, 2009When I put a break point to the last if clause in the sub ("If (backOrder < 0) Then", see below) it runs until the break point, if I put the break point further below, I get the following error:
Cannot insert the value NULL into column 'OrderID', table 'WHM.dbo.OrderDetails'; column does not allow nulls. INSERT fails. The statement has been terminated.
I've discovered first hand that it only happens when prodqty is bigger then qtyOnStock, thus executing the if clause.
The code:
Private Sub NCOSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles NCOSubmit.Click

View 1 RepliesApp Makes Use Of Many Queries And Commands?
May 6, 2010I have a data driven application in <acronym title="Visual Basic">VB</acronym> which works with an SQL Server 05 Database.Since this app makes use of many queries and commands, occasionally i'me getting a timeout error as the connection pool is full. So i figured that at a specifc point in time within the app,i'll clear the connection pools using the ClearAllPools method rather than increase max pool size.
I'm using the performance monitor on my XP development machine (NumberOfPooledConnections) however not once do i see the number of Pooled Connections reset to 0 even when that method is called.How can I determine that my solution is working (if it is) before I deploy the update?

View 1 RepliesIs BindingSource Class Makes Use Of Threading?
Dec 8, 2010Is BindingSource class makes use of Threading to read and write the values in controls and in objects?I mean how bindingsource know when properties of an object changes and sometimes seems not to know? Does it use a kind of BackGroundWorker running to watch changes on bindings objects? And why does it sometimes read and write properties so many times the same value on the same object's property?I found that it's sometimes easier not to use them since it's hard to know why a control do not update but, on the other hand, dealing with control events can be tedious. And what if i tried to make my own BindingSource Class not inherited from the System.Form.BindingSource

Feb 12, 2012I have a custom NumericUpDownColumn in my DataGridView. Problem is that when I type in a 0 in those cells it automatically changes to DBNull, this causes all sorts of problems with other code. I found the code for the custom column through a google search and don't know enough code to actually go through it and fix the problem myself. If I change the column to a TextBox column instead, it shows a 0 instead of DBNull and everything works as it should. So I figured the problem must be within the code for the custom column.

View 14 RepliesUser Makes Multiple Entries In A Single Day?
Mar 19, 2012i have an access 2007 database in wich i have a table named abc_PersonalLog, wich also has three columns: Id (auto number), StarDate (text) and LogEntry (Memo). It is a Diary application. So, when the user makes a log entry, the StarDate column receives a string formed of concatenated year, month and day, i.e. if date is 20th march 2012, the string will be 120320, and the Log entry column, the text entered by user in a textbox.My problem is that, somehow, i have to retrieve that data, when the user will want to read log entries he made. I managed to assign the text property of a label to the LogEntry text for a given date.But, if the user makes multiple entries in a single day, the table will have several rows containing the same string in the StarDate field, but different text in the LogEntry fields. How can i display ALL the LogEntry texts for all the rows containing the same StarDate value? Here is my code so far:
