Simple Parameter Passing To Oracle DB?
May 1, 2012Im using a datatable and i am trying to do a insert statement into an oracle database by passing selected values from the datatable to the insert statement via parameters. I'v traced the parameter collection and it has the correct number of parameters to be passed but it is giving me an error saying a value being passed in is null but it is not, during debug you can clearly see the value of the parameter is not null.
Dim FuelInsert As String = "INSERT INTO table (COMPANY, TRAN_DATE, GAS_GALLONS,DSL_GALLONS,DEF_GALLONS,KER_GALLONS,E85_GALLONS,DDS_GALLONS,WDS_GALLONS)" _
+ "VALUES(:Company, :Trans_Date, :Gas_Gallons, sl_Gallons, ef_Gallons, :Ker_Gallons, :E85_Gallons, ds_Gallons, :Wds_Gallons)"
[code]....
I just wanted to know if there was a easier way of creating the parameters or if i am missing something simple that causing the values of the parameters being passed to get mixed up. The code retrieves the values i need and builds the parameter collection of 0-8 nodes which is correct.

Passing Parameter (Value Or Referenced Type) Into Method?
Nov 11, 2009What happened when parameter passing. Here is a test project I write.
Public Class Form1
'1.test string
Private Sub btnString_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnString.Click
Dim str1 As String = "x"
[Code] .....
From the project you can see, when pass integer type parameter (value type) into a method , if use ByVal keyword, the value won't change. If use ByRef keyword, the value will change (I can understand it, to my understanding, when using ByVal, It pass the value of the argument to the method; when using BvRef, it pass the address of the argument to the method, so the value can be rewrite)
Well, for the following two scenarios , I can't understand why.
String type is reference type, but it acts like integer type.
Val type is also reference type, but no matter what you use(ByVal or ByRef), the result will be the same.
So my question is what actually passed into method? What's the underlying mechanism about pass parameter? What's the effect of ByRef and ByVal to value type and reference type?

SQL Adapter Not Filling Or Erroring Out?

On a certain Pc the first combo fills in and the 2nd does not.It never timesout and no error msg is ever rpted back. It just sits there forever after the adapter.fill cmd.Only difference between the first combo fill and the 2nd is a different connstr.Only 12 rows should come back from the Db. I have connected to Db in SQL query window and ran the SQL cmd and the 12 rows come back in a second or 2.On other PCs this same app works fines. I have the PCs on the same OS and all the newest updates installed.I have tested the network ports, used different ones. Used different user log ins on the same PC. It just wont work.

View 8 RepliesPassing An Event As A Parameter
Jun 10, 2011I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this. As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:[code]Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:[code]So far, the "evt as Event" part of the argument of the setHandler function is giving an error. Any ideas on the right way to do this will be very welcomed.
View 2 RepliesPassing An Event As A Parameter?
Nov 10, 2010I need to pass an event as a parameter to a function and I'm wondering if there is any way of doing this.
The reason why I need to do this is because I have a sequence of two lines of code that is littered all over my program, where I dynamically remove the handler to an event, then set the handler again. I'm doing this for several different events and event handlers, so I've decided to write a function that does this.
As an example, let's say I have a combobox in my code called combobox1, and I have the handler called indexChangedHandler. In several places of my code, I have the following two lines:
RemoveHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler
AddHandler combobox1.SelectedIndexChanged, AddressOf indexChangedHandler
Now, I don't want to keep on repeating the above two lines of code (or similar) all over my program, so I'm looking for a way to do this:
Private Sub setHandler(evt As Event, hndler As eventhandler)
RemoveHandler evt, hndler
AddHandler evt, hndler
End Sub
so that everywhere where those two lines of code(or similar) occur in my program, I can just replace them with:
setHandler(combobox1.SelectedIndexChanged, AddressOf indexChangedHandler)
So far, the "evt as Event" part of the argument of the setHandler function is giving an error.
P.S I've asked this question on a couple of other forums and keep getting asked why I would want to set the handler immediately after removing it. The reason is because dynamically adding an event handler n-times causes the handler to be executed n-times when the event occurs. To avoid this, i.e to ensure that the handler is executed just once when the event occurs, I first remove the handler each time I want to add the handler dynamically.
You might be asking why the handler would be added several times in the first place... The reason is because I add the handler only after a particular event, say E1, in my form has occured (I add the handler within the handler of event E1). And event E1 can occur several times within my form. If I do not remove the handler each time before adding it again, the handler gets added and thus executed several times.
Whatever the case, the processing occuring within the function is not of ultimate importance to me at this time, but rather just the means of passing an event as a parameter.

VS 2005 Passing A Parameter With AddHandler?
Oct 2, 2009From what I understand, when you use AddHandler you're not actually calling a Sub, so you can't pass a parameter. I'm confused on what to do though about this. I've just populated a DataGridView and added a button to it in the codebehind. I'm then using an AddHandler to add a click event to the button. So when I get to the click event, I need to be able to access to the datagridview because clicking the button takes data from the datagridview and loads it into excel. What would I do about this. This is my Method where DataGridView was just populated

I read somewhere long ago, that it's better to assign the method to a variable and pass that variable to a method, as opposed to passing the method as a parameter. Is that still true? Or true at all?
