consider the following code and comments:
Console.WriteLine(1 / 0); // will not compile, error: Division by constant zero
int i = 0;
Console.WriteLine(1 / i); // compiles, runs, throws: DivideByZeroException[code].....
This test seems to corroborate the idea and a literal double of 0.0 is actually a very, very tiny fraction which will result in Infinity...
i have a function which accepts a date and two byte variables. However when the function is called the date value passed to the function comes from a datepicker in the format of (dd/MM/yyyy). I noticed that the date parameter is changing the format to (MM/dd/YYYY).
i want the date value to remain in the format of (dd/MM/yyyy), i have enclosed by function.[code...]
I'm creating a Chart using the .net 4.0 System.Web.UI.DataVisualisation library and have noticed an odd behaviour.
First I'm creating a Series with two datapoints, each with the same value on the X-axis, as follows:
Dim series As New Series()
series.Points.Add(New DataPoint(0, 10))
series.Points.Add(New DataPoint(0, 15))
[Code]....
Then, the chart still only renders two points on the X-axis (0 and 1), and the first two values (on x-Axis value 0) are connected vertically!
Anyone know why this behaviour is different? Either behaviour would be acceptable really, but I'd like to be able to choose one of them...

View 8 RepliesI have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.

Is there a function in VB.net that allows me to divide a really long String into a specific number of characters? [code] The length of this string is 18 and I'd like to group it by 3, so each group would contain 6 characters. Is there an easier way of doing this? Is there a predefined function in VB.net? I'm already thinking of doing it manually, like converting the string into characters and storing them inside arrays.

i have two textboxes where a numeric value will get entered into both, these values will then be taken and the first value divided by the second value. The problem i am having is that if for example the first value is 11 and the second value is 10, when i divide 11 by 10 the result is 1. I have tried setting the output format to have 2 decimal places but it still displays 1 instead of 1.1. [Code]

Dim fault As Double
Dim ng As Integer
Dim input As Integer
[code]....
Halo, may i ask how can i save my answer fault into database after i done division. I am taking the data from textbox(input data) and done the back coding division.
If
strOperand = "/" Then
intLast = intFirst / Val(
Me.TextBox1.Text)
I'm not getting a remainder like I would have hoped. I'm new and I'm sorry for the lack of intelligence on the subject. To my understanding the Val( function will convert the string to a number, but when I divide it gives me a single number instead of an integer.
Let say I had a project contains 10 forms and 10 reports and typed dataset (xsd)I am trying to divide my project forms into dlls, so when the client had a problem or asks for modification in single forms, I had to build the project all over again and the exe size will be large.
in my current project, the exe size is 4.8 MB, and I am working with customers by internet and remoting, so every time I make small changes (change the back color of textbox in one form) I had to rebuild and send the whole 4.8 MB to the customer. And not forgetting the increasing size of the exe with time.I know that converting my project to class library and built it will convert it to dll, so I had to create a second project to manage it.
1 - Can I convert 3 or 4 forms / 10 forms total in my current windows application project to dll?
2- What is the best recommended method to divide the project into smaller entity.
I need to compare two dictionary values if the types stored are equal, this is what i have

How to use a .Net 3.5 Behavior in WPF .Net 4?
I get this error when I use .Net 3.5 in .Net 4:
Found conflicts between different versions of the same dependent assembly
I can solve problem with double click on that warning but it doesn't work in design view (It works for building well).
I'm writing an in-house intranet application in ASP.NET and VB.NET. My 'customers' are beginner to medium-level users. All of our browsers are IE8 and above, standard.The application works great, except for one thing. The backspace key. When a user types an invalid number into a textbox, a RegularExpressionValidator and ValidatorCalloutExtender fire off and notify the user. Perfect. Except that, when the user closes the popup warning and notices the cursor is still flashing in the textbox, he/she feels it's time to hit the backspace key and delete that pesky field value.
Unfortunately, the browser interprets this action as a desire to go 'back' into the page history. My boss is screaming. His bosses are screaming. I have a headache.So, how can I turn off this behavior? I still need the backspace to eliminate characters in the textbox, but nothing else. Company policy here: Backspace is to delete characters from the screen. Nothing more, nothing less.
Strange vb.NET application behavior/One application e.g. does some recursive operations against a ftp server as it synchronizes a local directory with a remote directory. When this part is finished, recursively I loop through the local directory to compare each individual file with a hash code table file retrieved from remote to be sure the source file and the destination file are identical. The processing speed to me during the coding was really satisfactory, but all over sudden the all over performance has been reduced by factor 3. So what happened was I closed an application named TeamSpeak. As you can guess it took me a while to figure out what was happening. This behavior is reproducible even with other applications like Outlook or Winamp?To make it short: e.g. TeamSpeak is up and running, my application runs 3 times faster than without TeamSpeak up and running ... same code - no changes !!!
View 1 RepliesI have a combobox in a Windows form. I set the properties of the combobox as follow:
AutoCompleteMode: Suggest
AutoCompleteSource: ListIems
DropDownStyle: Simple
DataSource: some binding source
Problem when user enter value to the textbox and open the dropdown and filter out the dropdown list. When user mouse click an item in the dropdown list, it will not select the item and paste it to the textbox. User uses the down arrow to navigate to the item and click on the "enter" key and it will not paste the selected item to the textbox. The only way to select an item is using the down arrow key to navigate to an item and then "Tab" away and it will paste the selected item to the textbox.I want to be able to use mouse click or "enter" key to select an item from teh dropdown list.I want to set the DropDownStyle as "Simple" so user can think it is "textbox" and start entering value to it.

There are few steps to find out the half slopes of the graph.
Step 1: Rank the data The independent variable is required to rank it from the lowest to the highest.
Step 2: Divide the data Divide the sample size into 3 roughly equal parts, which is the lowest, middle and the highest parts. If n/3 has remainder of 1, +1 into the middle part. If n/3 has remainder of 2, +1 into the lower part.
Step 3: Find the median The size of each part = n, find the ((n+1)/2)^th value for both dependent and independent variables. If the ((n+1)/2)^th is not an integer, sum up the 〖n/2〗^th value and ((n+2)/2)^th value and divide the total by 2 to make it as median. The median, m1 for independent variable in lower part indicate as XL , middle part median, m2 as XM and the highest part median m3 as XH. For the dependent variable the median is indicate as YL, middle part as YM and the highest part as YH . Figure 3.2 Example of median m1, m2 and m3
Step 4: Find the half slope Find the half slope for the lower half, b_L=(Y_M-Y_L)/(X_M-X_L ) and for the upper half, b_H=(Y_H-Y_M)/(X_H-X_M ) .
Step 5: Find the half slope ratio, b_0=b_L/b_H . If the ratio is negative, the dependent variable need to add with a constant, c in order to make the slope same direction.
Step 6: Identify transformation. Depend on the graph pattern pick one type of transformation which is nearest to the original of the variable.
Step 7: New half slope Find out the new half slope ratio, b1 by repeat step 4 and 5 with the transformed variable.
Step 8: Repeats steps Repeat step 6 and 7 with choose the transformation which is nearest to previous transformation and find the new half slope ratio, b2, b3,�, bn. Repeating this step until |1-b_i |≤|1-b_j |, for i<j, i and j = 1,2,3,
Step 9: Result bi is chosen. The data transformation used in bi is the most closest to be normality.
