VS 2010 Check If Value Has Decimals And If It Has Decimals, Remove Them?

May 19, 2010

Dim y as integer
dim x as double = 125 / 60
y = Convert.ToInt32(x) 'removes decimals

That method works, it removes all the numbers after the decimal.

But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?

I have tested all the possible solutions i can think of, but I always run into a lot of errors

How To Get Total Sum From A Listbox And Display It Automatically Into A Textbox

Mar 15, 2012

Ive got a Listbox which displays a data/record from a SQL database, it displays "Amount" and only numbers would appear. it has a datasource.

Goal: I'd Like to get the total sum of those numbers from the Listbox and Display it to a textbox automatically or by button click event.

I thought of two ways to do this, but I don't have a clue on what to do.

1. I tried summing it all up on that exact Listbox and display the total on the textbox, here's the code that i came up with..

[CODE]...........

But the data im working with is from a database, so i got this error:Conversion from type 'DataRowView' to type 'Double' is not valid.

2. I thought of having another Listbox and "Copy" the contents shown on the Listbox1 and then sum it all up on the Listbox2, then lastly display the Total on the Textbox. I did a little research on how to accomplish that but all the clue i found is that i have to disconnect the listbox data from the datasource from being bound, and reconnect it again.. I really don't have any idea on how i could do that with an SQL database.

Here's a quick flow on what im trying to accomplish to make things.

Record from Database -----Displays on---> Listbox1 -----User Clicks--> Button1 ----Displays Total sum on----> Textbox1

Payroll Calculator - Program Must Calculate And Display The Total Pay In The Total Pay Label

Oct 6, 2010

The pay rates for the project are:

a. Level 1 - $10.00
b. Level 2 - $12.00
c. Level 3 - $14.00
d. Level 4 - $16.00
e. Benefit Deduction Rate - 0.10
f. Overtime Factor - 1.5

For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.

When the Calculate button is clicked:

a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.

1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.

2. If the user chooses to continue processing, the focus must be set to the Hours text box.

3. If the user chooses to quit, the program must close immediately.

b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.

1. The pay rate is determined by which Job Grade radio button is checked.

2. For hours less than or equal to 40, the total pay is the hours times the pay rate.

3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.

4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.

5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal
places.

6. The focus must be set to the Hours text box.

Why i get an error when i try to run this code

Code:

Also the message box, both yes and no close the program.....

Forms :: ListBox Doesn't Update Contents

Nov 29, 2010

I have a form called 'Bookmarks' that loads a bookmark file that contains a single word on one line. I have put buttons on the form for sorting this list, deleting items and changing the character case to lowercase, uppercase or Sentence Case.Now, deleting and sorting the list works fine, but when I try to change character cases,nothing happens. I started the debugger and found that my case changing code does work, but the listbox doesn't seem to update it's contents.I tried listbox.Update() and listbox.Refresh() but that didn't work either.

Here's my code for 'Set Case':

Private Sub setCase_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles setCase.Click
If bookCase = "default" Then Exit Sub
If bookCase = "lower" Then

VS 2010 Remove From Listbox If It Doesn't Exist?

Mar 7, 2011

What i need is, if a item in a listbox Doesn't exist, it needs to remove it from the other.

In the pic i have attached. Basically If it doesn't exist in Listbox2 then it needs to be removed from Listbox1 and tell the user which one has been removed.

i.e Test 02 doesn't exist. So messagebox would show "test02 has been removed" then remove it from listbox 1

It probably something simple thats sitting in the back of my mind, but for the life of me can't figure it out lol

Loop Through Top Level Folder In Mapped Drive And Give Total Count Of Files And Total?

Oct 28, 2008

I am working with VB 2008. I want to be able to run this program say in N: and it will show me in an excel sheet the following:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308

where clients contains subfolders and files and the size is the total of all those files within each folder and the count is the total within each folder also.

This works fine as it is but i have to select one by one the top level folders and some of them are huge so it takes forever to give me an answer.

1) I would like to see in my spreadsheet the following by only select the network drive n:

Folder Path Size(GB) Count of Files
N:Clients 0.53 308
N:Software 10.7 15430
N:Billing 0.98 105

2) I would also like to know if this is the faster method.

3) I tried adding a progress bar so that the user can have an idea of how much this will take but i had to remove because it was not working.

4) I would like to see the folder name, size of folder and count of files in the listview.

Here is the code:

Imports Microsoft
Imports Microsoft.Win32
Imports Microsoft.Win32.Registry
Imports System.Collections

Adding Another Total To An Existing Total?

Nov 21, 2009

I'm new to forums as well as new to VB 2008. I'm in process of making a order calculator which will total any values you selected in combo boxes/checkboxes and then display it in a selected area. There are 3 things that I want to achieve: 1. Be able to add another total to an existing total (currently I'm able to see only one total when I hit "Calculate" button)2. Display how many orders I have made so far (new total counts as one order)3. Be able to add up checkboxes selected to an overall total. (when I try to add up one checkbox with another it seems to be stuck on 1.5 pounds which I assigned for each "side order")

Mod The Numbers After The Decimals Only?

Oct 22, 2010

If i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g

If VarWholeNumber MOD 10 = 1 Then
......
Endif

But if i have a whole number with format "0.00" how can i only check if the last 2 digits after the decimal is a mod of 10 regardless of what the whole number sides value is.

So something like

If VarWholeNumber's ".00" MOD 10 = 1 Then
.......
Endif

How could I could this?
