Call Function - Invalid Attempt To Read When No Data Present

Mar 25, 2009

When I run my application the following code prompts an error. Ideally, I want to populate the TxtOracleNo with a value read from another table on my form based on certain conditions i.e., prac_no, prac_eid and pay_method is the same in both tables then populate the Oracle No on TxtOracleNo text box.

The error given is
"Invalid attempt to read when no data is present"

The function is shown below
Private Sub Oracleview()
'Open the database.
'Delete any existing record
Dim cmd As New SqlCommand
Dim conn As SqlConnection = GetDbConnection()
[Code] .....

I checked that data in the database and it is available in both tables. Probably, the problem is where I call the function. Presently, I call it on loadform.

Invalid Attempt To Read When No Data Is Present

Jul 18, 2012

In a nutshell...I have developed a site in ASP.Net and VB.Net which allows a user to create an order and submit it to a SQL Server backend database.

When the order is placed...an xml file is also produced, showing the items that have been ordered...which is then loaded in to a program to update stock quantities.

The code I have is as follows:

Public Sub butSubmitOrder_Click(sender As Object, e As EventArgs) Handles butSubmitOrder.Click
Dim sqlConn As New SqlConnection

"Invalid attempt to call Read when reader is closed." is returned when trying to use a SqlDataReader in a Thread or BackgroundWorker (Do While z.rdr.Read() in the bold sections - I know this code does the same thing twice....).

Time To Call A Function To Change Data Being Returned From Database?

Jun 28, 2009

I have two functions written in VB.NET:

1) The first function (call it GetValues()) returns values in a SQL database as a list via a stored proc. One of the fields is DateTimeSubmitted. All of this data is displayed on my webpage using a repeater control. It works fine.

2) The second function (call it NiceDate()) I created to change the DateTimeSubmitted to a nice date such as "one minute ago" or "yesterday".

My problem is I have no idea which is the best part of the process to do the conversion (at point of data extraction or in pageload etc.) or in fact how to do the conversion.

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

Apr 1, 2010

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Here's my call:

<script type="text/javascript">

function HelloWorld()
{

var yourName = $get('txtYourName').value;

Use The Timer_Tick Function, To Loop A Data Read From A COM Port?

Jul 2, 2011

I should use the Timer_Tick function, to loop a data read from a COM port. The object i call uses a method that closes the thread after a fixed timeout.

obj.Read(N byte) //--> if no data come within 500ms close the thread

My question is: considering that the Timer_Tick function will be called every (for example) 100ms, How long does the total execution last? Timer_tick time + Thread Timeout (100ms + 500 ms = 600ms) or just the Timer_Tick time (100ms) causing the anticipated thread closure/crash?

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished

Jan 25, 2010

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).

Anyway what I am trying to do in steps:

1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.

The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.

I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?

Sep 14, 2010

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()

takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:

Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)

Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

Override A Function And Call A Function With The Same Name From The Grandparent Superclass?

Sep 6, 2010

I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.

In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

[Code]...

Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.
