Mar 9, 2011Me.Width is what i am having issues with. I can adjust the width to work on my system but the bar is a different amount of pixels on different versions of windows. I was wondering if there was a function that would give u the amount of pixels the side bar is. I was considering writing some code so look for a color change but people can change the color so i do not think it would work very well. Also the program allows you to draw in a picture box so that would make it hard to get it to work correctly.

Subtracting Time From Date Object?
Jul 15, 2011I'm subtracting hours from a date object like so:
startDate.AddHours(-7.0)
endDate.AddHours(-7.0)
However It doesnt seem to affect the day of the object. My question is this, when subtracting hours from the object does it subtract it from the global date? I.e make "May 7, 2011 1:00:00 AM" into "May 6, 2011 6:00:00 PM" when subtracting 7 hours or does it just affect the hours of the object?
Forms :: Find If Times Is Between 2 Times?
May 13, 2009I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

View 1 RepliesFinancial Calculations - Strange Result When Subtracting Numbers
Mar 17, 2011Do a simple thing first... open VB.NET, then open your Immediate Window. And type the following:

Its a simple mathematical sum which should return the answer as -466.52, but instead it shows -466.51999999998952. My project which is mainly about financial calculations has gone all screwed up because of these two numbers. All the amounts in my project are based on Double type numbers. Since this calculation is showing a strangest kind of a result, all my program code has gone haywire.
Forms :: Subtracting A Value From A Text File Via A Button Press?
Aug 23, 2010I have built a program in where I have to add and remove items from two listboxes. Listbox1 consists of a file which I have picked up on my C:/. Within this file, are different lines of items. At the end of the item line is a figure. I have a textbox in where when someone adds the an item from listbox1 to listbox2. On clicking the add button, it will add the total which was in the file. If I add more items, it will give me a running total of the items I have added to listbox2.
Now, I'm bamboozled in how to subtract the items from listbox2 with the remove button. So that when a user wants to remove an item that they currently placed in Listbox2. On pressing remove it will subtract the running total from the item which has been removed.. Here is my code in where I add products to the textbox. I have two other text boxes which I use to have these running totals. FYI, Textbox where value is outputted is Textbox5. Textbox6 is used to refresh the data and the other textbox is named 'Total'.
Public Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
If ListBox1.SelectedIndex < 0 Then

Transfer Of Content Multiple Lstbox On Two Forms/subtracting Finances?
Jun 12, 2012I'm current doing a computer course at college, one unit being event driven programming - for this I must design and program a till interface?
- One being on each form I have a virtual receipt named lstbox, and I have multiple forms! The problem is the content of each form is not transfering to the next virtual receipt on the next form e.g. drinks selection form 1 you select a tea, it adds to the virtual receipt, but when you hit the button to go to the next selection form, the content of the virtual receipt does not carry over. Could you please help me ?
- Secondly, I have a payment form on my till interface which obviously allows the user to finalise the transaction by taking payment from a customer, what would be appropriate code to use for when working out customers change e.g. If you hit a �10.00 button for customers change, and the charge of the transaction is �6.00 - I wish for an output of amount of change to go to the customer!
Note - I have a vat, subtotal and total text box for where the data displays. So whether to take away from the total text box and work out change that way, or to use the correct variables in my program such as itemcost variable, order variable etc.
Events -
- Selection of item -

VS 2010 - Subtracting - Subtract From Textbox1 And Place The Output In Textbox2

0x08800000 0xDEADBEEF
0x08800000 0xBEEFBEEF

I only need to subtract 08800000 from whats in bold, the rest will stay the same. The value in textbox1 will always begin with 0x0880xxxx I need to convert that to 0x00000000 so basically I need to subtract 08800000 from textbox1 and place the output in textbox2.
