View 2 RepliesI have a web page where I want users to enter ratings for a particular software. I have got this working fine. What I am after now, is that users need to be logged in to enter ratings. I have dragged the loginview control onto the page and dragged all the other controls/datasources into this view. However now I am getting alot of squiggly lines regarding my controls not being declared. I have been told that I need to use the FindControl method. However I'm not sure on how to use it in my instance as I have a dropdownlist involved.
The controls are called: LoginView1, DropDownList1, TextBox1 and Button1 for the insert.
Any proper declarations so I can insert data into my database. Here is the code as it stands outside of the loginview:

I setup a strongly typed dataset using the DatasetDesigner in VB2010. I am using the TableAdapter.Insert method to add data to an Access table. Before the data is inserted I need to validate the data using the DataTable RowChanging event.
How can I get the DataTable RowChanging event to fire when using the TableAdapter.Insert method?
Here is an excerpt of code I have so far:
When the Insert method runs, it does not fire the datatable RowChanging or NewRow events.

I need to explicitly load my data source variables and then call the insert method associated with the data source. The sample VB .net code is listed below. So is it sufficient for me to just call the Insert() method when I am ready to insert my values? Or do I need to create an insert event? You see if I look at the properties window for the data source, there is a lightning bolt icon that will generate events for the data source such as Insert,Inserting,Disposing,Init,Load etc.

May i know how to insert a AT command method inside my program to receive incoming sms?
My program is in visual basic windows form 2005.
Here is how my program goes.
After i click connect button in my application, the gsm modem will automatically read the incoming sms and display in the textbox on the program.
I already have the list of AT commands to be used, they are :
1. AT
2.AT+CMGF=1
3.AT+CMGL="ALL"
I also would like to know how to declare these commands as string inside the program.
Here is my program so far:
CODE;
This code is for the user to click on connect button which will connect to the serial port. So after connecting the modem will then auto read and display new incoming sms.

[Code]...
However if run in another thread it causes a cross threading error.I have looked at examples of delegate subs that use Invoke, but all examples i have seen involve updating the text property of an object, and i cant get my head round how to apply the concept to actually add a subitem to a listview.
im trying to add a text changed method to my listview item. all the items are dynamicly created so i would think id have to use an addhandler listviewitem1.textChanged addressof listviewitems_click where listviewitems_click is the generic sub to handle the click. but the listviewitem control doesnt have a text changed event, but you can rename the text in the control anyway.

I have a shopping cart ListView control backed by a custom object that has methods for selecting and deleting. In the ListView, one of the columns is an ImageButton that is essentially a delete icon, with the CommandName parameter set to CommandName="Delete".
My issue is related to updating the shopping cart ListView on delete; as the delete method is stored in the custom business entity object, I am having trouble in terms of updating the calculations made inside the cart (we have deleted an item, so I need to recalc shipping, taxes, etc).

When ListView is not in Virtual mode the following method seems to be the fast method to load a large list into ListView:
Dim items As New List(Of ListViewItem)
Dim alllines as String()=System.IO.File.ReadAllLines("FilePath")
For each line as string in alllines
Dim item As New ListViewItem
item.Text = line
items.Add(item)
Next
ListView1.Items.AddRange(items.ToArray())
