Convert The Decimal To An Integer And Then Use A While Loop For Every Text Box?
Jun 21, 2010
I am new to vb and need some help with this change program. The idea is that we are given a certain amoun of change and then telling how many dollars, quarters, dimes, nickles and pennies. I thought I would convert the decimal to an integer and then use a while loop for every text box, i.e. dollars, quarters, dimes, etc.., to show how many of each, but the while loop is confusing for me in vb, but to tell you the truth I don't know if I am on the right track,

I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

The code below works until I try to convert the text box to a decimal. I think it might be because at the time of conversion the text box is empty. If thats the case, where could I do the conversion?[code]...

I am trying to understand the do until loop when adding numbers along with a variable to a new line in a textbox, incrementing each time. My current example is very simple but only returns the first value. I require the output to be incremented automatically, so I thought a do until loop would be best.

Currently using VS2008, VB.NET, SQL.
I have a FormView from a Data Source that is getting some fields that are stored as Decimals in the SQL Database.
I am grabbing the field from the FormView as such:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
I need to take this value, and convert it to an Integer, then send it along to an API. I have the API Calls done, tested and working, but I'm getting an error as when it is getting this value, the API is returning "Must be an Integer" error.
What I have tried so far:
Dim AvgTicketL As Label = CType(frmMerchantProfile.FindControl("F10Label"), Label)
Dim AvgTicket1 As Integer
AvgTicket1 = Double.Parse(AvgTicket.Text)
Do something with AvgTicket1
I have also attempted to Round the Value, then convert it and call it - no luck.
Checking the value of AvgTicket1 (Writing it out to a Label or Response.Write) shows "100", where the database value was 100.00. But the API is still getting 100.00, apparently. Any other conversion method that I've attempted states errors that the Label cannot be converted to Integer.
What are some methods I can successfully convert this value to an integer from a label?

So, yes, I've tried with these three formats, and the problem remains the same:I have a string, "s"For Each s As String In stringarray and this array is recieving data from a streamreader that is reading a csv file. The data I'm having dificulty reading are these very specific numbers(yes, only these numbers, because phone numbers get home safe and sound).The numbers I'm talking about are usually decimal.ValueList.Add(Convert.ToDecimal(s))
Now, when I convert them like that, they always bring a "D" alongside with them. I've personally checked the string multiple times, and it just has a "1", and somehow, my list recieves "1D" as a number, same thing happens with decimal numbers(0.29D for example). I've tried with Doubles and Integers, the result is the same.

I wrote a loop that posted an accrued principal cycle to a listbox for a period of 10 years (10 loop cycles). The problem is: not only does the amount of the principal reconfigure for each loop cycle, but it does not truncate into a two decimal place holder as it should. I would like to use the ("F2") but I am not sure where to put it within the code. Here is what I have for the Calculate button event handler.

I am trying to convert information stored in a file to a decimal (or ASCII) format, then write the contents of that file to a new file.
What I have is a list of files that are generated from a cash register. The documentation that was provided to me says that this particular file I am trying to work with has a length of 6, a width of 6, and that it's BCD type.
I've done quite a few google searches and can't seem to find a good solution. I know BCD numbers should be stored as 0000 format. But the problem I'm getting is when I read each part of the file (using my sr.read) I'm getting full numbers..and I am expecting the 0000 format. I'll get a 0, 0, 0, and then all of the sudden I"ll get a number that's 65,000..then I'll get a 34...and there doesn't seem to be any
I'm sure I'm doing something incorrect here, my knowledge of reading HEX, BCD, etc. is very minimal. I'm guessing it has to do with using a filestream, so I can use the fs.ReadByte() method..but when I tried that my program was literally chugging along for several minutes with no sign of ending.[code]...

I want to make it so when cancel is used it exits the loop but I need the Input as a decimal.
Do
txtItems.Text = intCounter.ToString
intCounter = intCounter + 1
msgInput = CDec(InputBox("Enter Item Price", "Item Price", ""))
decSubTotal = msgInput + decSubTotal
txtItemPrice.Text = msgInput.ToString("C2")

i tried this, but had invalidcast at line 2.
vb.net
Dim a As Array = Array.CreateInstance(GetType(Integer), New Integer() {1}, New Integer() {1}) Dim b As Integer() = CType(a, Integer())
what i'm trying to do is to create an Integer array with LBound greater than 0. any way would be accepted, or can i say this: my function that takes i As Integer() as its argument does not have to check the LBound of i because there is no way LBound of i will ever be greater than 0

Can a VB.NET For loop be constructed that mimics this C# code?
TimeSpan oneDay = TimeSpan.FromDays(1.0);
for (DateTime d = startDate; d < endDate; d += oneDay) {
// some code
}
Obviously you could do it without a For loop (i.e., with a While); I'm just curious if there's a certain syntax to construct a VB.NET For loop with a non-integer increment that I'm not aware of.

Let's say I want to convert a Double x to a Decimal y. There's a lot of ways to do that:
1. var y = Convert.ToDecimal(x); // Dim y = Convert.ToDecimal(x)
2. var y = new Decimal(x); // Dim y = new Decimal(x)
3. var y = (decimal)x; // Dim y = CType(x, Decimal)
4. -- no C# equivalent -- // Dim y = CDec(x)
Functionally, all of the above do the same thing (as far as I can tell). Other than personal taste and style, is there a particular reason to choose one option over the other?
EDIT: This is the IL generated by compiling the three C# options in a Release configuration:
1. call valuetype [mscorlib]System.Decimal [mscorlib]System.Convert::ToDecimal(float64)
--> which calls System.Decimal::op_Explicit(float64)

Very simple, I click a button and it shows the answer in the label. The answer to this is: 00:02:38 (according to excel)
But I want my Vb.net to change the decimals into the time as excel would do so. The answer vb gives me is: 0.001833786. So how can I change a decimal into a time?
