I have a program and the program works fine. The only thing is that I want to shorten it up and stop using the same code over and over. I use the same redudant code through out the code. I want to write some functions in order to stop from having to use the same code over and over in my program. I wanted to know if someone could help me with functions: Here is part of my code below.

View 1 RepliesI have a dataset along with code for validation. When I use a datagridview and setting the EditMode to OnEnter I get the red exclamations telling me that I have an error when this is needed. This works all good. when I click the save button on the BindingNavigator, the application saves the record even when this validation is showing. How do I filter up this validation code through a datagridview and stop the program saving the data? If you need the code for more information, I will add this to the forum.
View 2 RepliesOut of curiosity, is there a way i can make a program stop or pause for a period of time (which i would choose) before continuing the code WITHOUT a timer.I think I've seen this done before, but I'm not positive.Also note that I'm talking about a forms application (not a console app if that would be any different.)
View 3 RepliesSome time ago, I did some F# programming, the following code is used to serialize/deserialize float32 array:#light
However, nowadays, I have to do some programming in VB.NET to serialize/deserialize float32 array again. As F# programming is not suitable for GUI, but GUI is necessary for my current programming.I want to know how I can rewrite the above code in VB.NET.For example, I have a float32 array, (I dont know what data type in VB.NET is equivalent to float32 array in F#) of (1.0, 2.0, 3.0); I want to serialize it using DataContractSerializer, then read it back so I can still get the same float32 array.

View 1 RepliesI have a START and STOP button and when the user clicks "start" the program does a whole bunch of calculations and all. However, I noticed that when I was testing the program I clicked STOP the program continues to execute stuff.
My START code is basically a while loop that iteratively does some calculations.
So I just put a boolean variable as the while condition and when user clicks stop its set to false and when user clicks start its set to true. However, when I click stop, the condition is set to false yes but it still executes all the code until the condition is re-evaluated right...so my question is how can I get out of the while loop when user instantly clicks "stop"?

View 2 RepliesWhat is the best way to write functions in Microsoft.NET (VB) to avoid memory leaks. I have always followed this style:
Public Sub TestMemoryLeak()
Dim testCon As SqlConnection
Try
[code].....
Here the connection reference is created before the TRY clause and is initialised after the TRY clause. I believe the connection is always closed and dereferenced even if an exception is thrown. Is this good practice? I see a lot of code that creates references and dereferences in the TRY clause, but this would mean that the memory is not correctly handled if an exception is thrown. Some developers say they don't like to clean up in the finally clause.

is it ever possible to write locking-features(for threading) with the language itself (this question is purely academic, I know no one will ever do it even if its possible (not me))?
A) In Java, is it possible to write thread safety functions with java alone, but without using any of the provided classes/language elements/syntax which offer this feature?
B) In C#, is it possible to write thread safety functions with C# alone, but without using any of the provided classes/language elements/syntax which offer this feature?
C) In Vb, is it possible to write thread safety functions with Vb alone, but without using any of the provided classes/language elements/syntax which offer this feature?

View 1 RepliesI am just starting out with a practice VB project which involves selling donuts and coffee. I have written out the code which the program works but the code is very messy. This program contains functions and radio buttons to calculate a subtotal, tax, and total due. There are four variety of donuts in Group Box 1 listed as: Glazed at .65 each, Sugar at .65 each, Chocolate at .85 each, and Filled at $1.00.
The coffee choices in Group Box 2 are listed as: None at 0.00, Regular at $1.85, and Capuchino at $2.50 each.I want the cashier to be able to select a radio button to choose between the donut choice in group box 1 and then choose one coffee choice in group box 2. A textbox calculates the subtotal, a textbox calculates a tax of 3%, and a textbox calculates the total due adding the subtotal and tax.
Everything works fine but Ias I said before it is quite messy which I keep making it worst.I need to write one function to calculate the donut, one function to calculate the coffee, and one function to calculate the sales tax. Then I need a sub procedure to clear the subtotal, sales tax, and total due amounts when a radio button is clicked.I have been working on this for the past month ,code I have so far:
Class frmMain
Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click
