VS 2005 - How To Convert String To Double
Mar 3, 2010
I am trying to convert a string to double and it is giving error. Bye the way it is not giving error on my PC but it gives on some pc's where other clients are using. String is retrieved from xml data.
<data><vitals>
<username>aiglemedia</username>
<balance>49.60</balance>
</vitals></data>
vb code
Dim curBalance As Double
xmlNode = xmlDoc.GetElementsByTagName("vitals")......xmlDoc contains the above xml data
curBalance = System.Convert.ToDouble(xmlNode.Item(0).Item("balance").InnerText)... I think so error is on this line.
Below is the link for the error given by the client who is using the app [URL]

Is there an efficient method in VB to check if a string can be converted to a double?I'm currently doing this by trying to convert the string to a double and then seeing if it throws an exception. But this seems to be slowing down my application.
Try
' if number then format it.
current = CDbl(x)

Iam using VB 2005 on Vista This is a sample of what I am doing:
Public Class Form 1 Dim WC As String Private Sub Button1_Click
[Code]...
How do I get around this? What I am trying to do is, I really want to use TextBox's for input to enter numbers when the program is running and I also want a MsgBox to appear if an input is not entered because these numbers are important to a final formula further down.

I need to take this string:
Dim tmpTry As String = "10, 20, 30, 40, 50, 52, 20, 20, 10, 35, 3, 8, 47, 7, 2, 5, 55, 8, 0, 0, 6, 55, 0, 2, 12, 0, 0, 21, 14, 0, 3"
And convert it to a double array:
Dim arrNumOfVisits As Double() = New Double(tmpTry) {}
How do i go about doing that?
FYI the arrNumOfVisits goes into a ParamArray System.Collections.IEnumerable()

Why is it that when I convert a string with value "22.882" to double, using Dbl() it loses precision and is converted to 2288.2?
I have to use a double since I'm using the constructor of System.Web.UI.WebControls.Unit[URL]..

For a labels text I need to use the & symbol in the text, so I did this:
Const symbol As Char = Chr(38) and I am using like this:
Me.Label1.Text = "Welcome to A " & symbol & " R Storage Management Systems" I am looking for this because it is how the business name is spelled: A & R Storage
any other Char symbol I use in place of 38 will display the Char, but not the ampersand, it leaves a blank spot. Any advice. And yes I know the & is used to concatenate string variables, but I should be able to use it as a Char.

If I try to display a command line argument that has double quotes around, the double quotes are always stripped off. How can I avoid this?
for example, the argument is "c:xx.txt" and this displays c:xx.txt instead Console.WriteLine((My.Application.CommandLineArgs(4)))

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)

Follow-Up available: There's a follow-up with further details, see Convert MBF to IEEE.
I've got some legacy data which is still in use, reading the binary files is not the problem, the number format is. All floating point numbers are saved in MBF format (Single and Double). I've found a topic about that on the MSDN boards but that one only deals with Single values. I'd also would like to stay away from API-Calls as far as I can.
Edit: Just in case somebody needs it, here is the VB.NET Code (it's Option Strict compliant) I ended up with (feel free to convert it to C# and edit it in):
''' <summary>Converts a MBF Single to an IEEE Single</summary>
''' <param name="src">The MBF Single value</param>
''' <returns>The converted IEEE Single value</returns>

Let just say I have an Integer like 10,000 (that's the VALUE in want to reach). So, I have another integer like 2500 (that's my current VALUE). Third I have another Integer about 350 PER HOUR. To reach 10,000 I need 7,500 (well I already have 2,500). How long must I wait to reach the 10,000 when the increase is about 350 a Hour. Okay, that's easy: 7,500 / 350 = 21,428571 Hours. BUT how can I convert this double to a timespan? Or how is it possible to add this double value to the current Date to get the Date + Time when I reach the Value?

I've been just making random programs trying to get the hang of the new language this time I was making a leap frog game where it switches back and forth beetween frogs every time a button is pressed. It also checks if the frog can land in the text box above the button pressed, if there is another frog there a message box will pop up saying sorry space is filled other wise the frog should land there.
[code]...
The error message says "Conversion from string "frog1" to type 'Double' is not valid." I understand what a double is but I've tried And If and that causes a bunch of errors.My Question is whats wrong with this cod and how can I make a double if statement???PS I did try to make an array to shorten this but thats in a different fourm will post URL later

I have a piece of code:
Dim Latitude As Double = row("fltLatitude")
Dim Longitude As Double = row("fltLongitude")
Most of the lat/longs that are being fetched from the db using SP are retrieved in properly, except for a couple of records which do not include a period to indicate a lat/long value.I have tried using these:
Convert.ToDecimal(Latitude)
CDec(Latitude)
decimal.Parse(Latitude)
but none of them are working.
