View 4 Repliesthe first is validating numeric input in a textbox to make sure it's got two decimal places. I think this should be really simple, but I'm totally missing it.The second is adding an extra summary line to a listview. I have it working with all the data required, but I need to add an extra line at the end showing some totals. How do I do this?

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

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..

View 3 RepliesHow do I enable a user to set the number of decimal places in my code?essentially I have multiple variables in my code ,different kinds of pressure for example and with each instance I declare the following;
txt_Alt_Press.Text = Strat_Press.ToString(Press_DP)
I then set Press_DP in a module, declared as a public variable,
Public Press_DP As String = ("F1")
So what I want to do is make the "F1" bit a variable in itself, so then the user can set the number of decimal places with a numeric up-down control.
how i can format a number to only show decimal places if needed?For instance...
string.format("{0:SomeFormat}", 26.9) = "26.9"
and...
string.format("{0:SomeFormat}", 26.0) = "26" 'Drop decimal for whole numbers

View 1 RepliesI need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.The summary menu item displays a message box that holds total sales,total commission,and total pay for all salesperson. Display the number with two decimal places and dollar signs. the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.The Color and Font menu items should change the color and font of the information displayed in the total pay text box.Use a message box to display the program name and your name as programmer for the about option on the Help menu.

So the issue is when I push the pay/calculate button everything is calculating correctly the first time, but then when I push clear to input another workers name and weekly sales and push calculate, my label is blank and does not display any info about the second worker. Then when I push summary after inputting the second worker, it's only displaying the total calculations of the first worker. I can't seem to figure out this problem on my own (After countless hours staring at my code I might add!), so I am hoping somebody can pinpoint what I have done wrong? EVerything else is seeming to work just fine.[code]...

View 3 Repliesmy application has a data table, one of the column set as decimal type to store number, data is read from a text file and store into the data table, then display in a datagridview, I found when that number is only 1 digit, that cell displays nothing (I think no number is being store in that cell), if I type a 1 digit number into that cell is fine. for example,
1.1 [ok]
12 [ok]
0.15 [ok]
4 [not display]
9 [not display]
-23.8 [ok]
so which data type I should use on this column, in order to display all this possible numbers
OK, I've got my program that works perfectly, however it is displaying the total from the calculations to multiple amounts of decimal places. If there a way to limit the value that is being displayed down to say 2 decimal places??

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

View 8 RepliesI want to assign a Value to a Variable of Decimal Type to do a calculation, but when I enter the decimal value (a 28 digits to the right of the decimal point - very long numbers) it gets altered. I give below what I was doing:
Dim MyNumber As Decimal = 0.7777777777777777777777777774
But as soon as I finish typing the number, it becomes 0.77777777777777779 and appears as,
Dim MyNumber As Decimal = 0.77777777777777779
And, when the cursor is kept over the altered number it shows as "Double, Represents a Double - precision floating-point number." How can I get the value I wanted to stay without getting changed? I was able to get this long Decimal value as the result of a calculation and get that appears in a text box in the same program. Is there anything I should change in the "Visual Studio 2008" to get this ?
I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?
I am pulling data from a local MSSQL database using a stored procedure, then send the data to a web service. Every part of the component works well except for a pesky problem will a DBNull being returned from the DataRow field, when I know that the field is not null and has valid data. The database and associated INSERT statements that add to this field are designed to not allow NULL entries. When I debug break the program on or right before the line that throws the error I see that the field has valid data for the current row.If I add a null check to the code (as below) the operation continues as normal:
Dim dataResultsTable = Me.myViewTableAdapter.GetData(int)
For Each myDataRow In dataResultsTable.Rows
If worker.CancellationPending Then

Why is the read operation returning DBNull instead of the data in the database?
EDIT: Just to be clear, the operation does return the proper data, but the data is not being saved into the variable.
i am getting the xml using readxml method. And then display the data in datagrid. But number type columns comes as string type in the dataset. So when datagrid displays , sortingdatagrid columns is not correct. For example it sorts like this:

Using Visual Studio I'm using TextRange processing a word at a time, parsing for figures and minus values etc. All of which works. However I have to honour the original number of decimal places in the figures, even though they may be 0's.ie -1219.0 and 1219.00 are both valid inputs the valid outputs would be(1,219.0) and 1,219.00, I can't just use tostring and stamp all of them as "N2" etc).I have to format including retaining the trailing 0 if necessary.I can use "#,##0.######" but that removes trailing 0's... ie both above example would be changed to 1,219 pos or neg.
