Im working on a program that is about to drive me nuts figuring out how to round and show only 3 or 4 numbers past the decimal placement and also show the scientific notation.
Here is an example of the code.[code...]
The problem here is that most of these calulations turn up so long that my text boxes just show a small portion of the answer. I have really investigated rounding and decimal placement but nothing seems to work...does anyone have a solution?
How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01
I've been trying get rid of decimals on a number, but I need the whole number, so I can't have it rounded. I've tried .ToString and Format(), but without any luck.
I have a bit of code that returns some stupidly long number, and i need it to round up or down to 2 decimal places. I've looked online but I dont really understand much of it (I'm still learning!).
I'm very new to VB 2008 and I need to round the result of a calculation to three decimal places after using a button click to complete the calculation. I've tried the Round function to no avail.
I have constructed my program. I had my price variable originally set to integer, but I found this was causing me errors as the numbers were just being rounded to the nearest 10 and not the exact decimal place.
I have since changed the variable to a decimal and now see this in the errors box, how do I elminate this error?"A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll"
Secondly, it is producing the correct price but only to one decimal place. How do I get it so it displays the price to two decimal places?
I have a series of text boxes with numbers. They are an array called txtBF(0 to 16). I am trying to take the value that is to be displayed in the text box and make it have only one decimal place. I have tried using this code below but I keep getting an error message Run Time Error 13: Type Mismatch.
txtBF(11).text = Round(txtBF(11).text, 1) and I have also tried this txtBF(11).text = Math.Round(txtBF(11).text, 1)
I have a program written in vb.net 2003 which has text boxes for integer input. When the boxes appear, they are filled with the default value of zero. When the program is run on a computer running Windows XP the cursor appears in front (to the left) of the zero, but when run on Windows 7, the cursor appears behind (to the right) the zero.
In xp, if the user enters 1 (one) a 10 is diplayed and the user must delete the zero. In Windows 7, if the user enters 1, there is a leading zero which disappears once they have exited the text box. Is there a way to force one presentation or the other?
Suddenly whenever I build my applications, although I get a "build succeeded" result - the executables are either not updated or updated in the "wrong" place.So for example if after succesfully building I press <F8> to step through the code I get a message saying the "source is different from when the module was built"I have no idea how to begin tracking this down - how .net determines the placement of files and so forth.
I'm new with VB and a time program I'm trying to complete is incorporating a tick event. I have the code I need to use, and have the timer placed within the VB Designer but when I start the debugging process, 12:00:00 pops up in the text box. I would like to have it start incrementing after I set the hour, minute and second and initiate the Set Time click event. The code I have for the timer is
I'm working on my final assignment for my Visual Basic class, and the last assignment is to create a program which stores CD collection information. It works fine, but the task is to create a structure for the input information and use it in the Add buttons click event code.I'm not asking to have my homework done for me, but i'd like some advice on where I should declare the structure and how. Everywhere I try and declare it, it ends up closing that particular sub procedure or section. I've tried looking up plenty of help sites to learn about structures, but sadly they and the book are both very vague. The instructor also mentioned padding each entry, but that I'm pretty sure I know how to do
I'm trying to do two things. I have a Richtextbox which i'm continously adding text to from a standard text box. I want that new text to appear at the beginning of the existing text, not at the end of the existing text.I've got the following code but it's not working. The new text keeps going to the end of the existing text.
Dim newtext As String newtext = TextBox1.Text RichTextBox1.AppendText(newtext)
I am trying to put an unbound button in the last column in a DataGridView control and it appears way, way off to the right when I run the app. I have to scroll all the way to the right to get to the buttons and then manually resize them to show up the way I want them to. I am using the Edit Columns feature found in the Smart Tag of the control. It works ok when I place them anywhere else in the columns! It only messes up when I try to place them at the end of the columns.
After converting all degrees-->decimal, and decimal-->hours, how can i use Tan, Cos and Sin formula in vb.net? I want the user must enter an input (which it is a coordinat-->i already convert the degrees-->decimal value as suggested by stanav and paul.
The questions like this (i only calculate on paper but dont know how to implement in code):
Input user need to enter: -latitude local (e.g. 1.4875) -longitude local (e.g. 103.3883333)
My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .
Maybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:
Dim MyNumer as TwoDecimalNumber MyNumer = 1.124 Msgbox(MyNumber) 'This would pop up a box showing "1.12"
Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.
Running total = 329430.75 New Withheld Amount = 710.79 Running total = 330141.54
[code]....
As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..
