VS 2008 Double To A Specific Format String
Oct 2, 2010I am making a program that shows a data of azimuth and elevation of a radar. Example:
Azimuth = 203.40

C# - Double ParseDouble - Input String Was Not In A Correct Format?
Mar 11, 2011I keep receiving this same error about 3-4 times a day and have had no luck tracking down how to resolve this issue. According to the stack trace, the error is occurring within the Microsoft.VisualBasic library so how exactly would I go about fixing this issue? Here's the report I send to myself and what gets generated by the server. Any suggestions would be greatly appreciated.
[Code]...
Update: I understand what the error is and what would cause the error to occur. The problem I'm running into is finding out where exactly this error is coming from within code. The stack trace tells me its coming from Visual Basic but there's nothing else. No line numbers, no other info about what function caused this error to occur, there's zilch to go on so I'm left scratching my head trying to diagnose something, that looks to be wrapped up in a .dll probably.
We're running Ektron 7.6.6 sp2 if that sheds any light onto the subject. Is there any way to get a more robust stack trace? I checked the event viewer on the server and the info i posted earlier is all that's displayed in the event viewer. Which is none to helpful.
C# - Format Double As String With Positive / Negative Symbol?
Aug 25, 2011I'm outputting a Double that can be either (+) or negative (-). If the number is a negative the symbol (-) is included automatically, is there a way to do this for positive numbers as well?
The only (horrible) way I can do this is :
If MyNumber <= 0 then
string.Format("{0:0.00}", MyNumber)
Else
string.Format("+{0:0.00}", MyNumber)
End If
Double.Parse % Percent - Input String Was Not In A Correct Format
Jan 19, 2010I have a DGV with a column bound to a Double. When I enter "1%" I get:
System.FormatException: Input string was not in a correct format.
I then try: MsgBox(System.Double.Parse("1%")) and get essentially the same error. (same for "$")
Is there a setting that will allow "$" & "%" as not only valid Double input but also do the correct adjustment for "%"?

In .NET String.Format Is Accepting Objects Of A Type That Don't Match The Format String
Jul 7, 2011I have a function that is getting passed a String and a DataRow.The String is a custom formatter. The idea is to do this
String.Format(passed_in_String, DataRow("ColumnINeed"))
The reason this is being done is at this point we have no idea what the column contains.However, if the formatter is "{0:MM/dd/yyyy}" and the DataRow("ColumnINeed") is an integer containing 42, String.Format is returning: MM/dd/yyyy In this situation I need it to throw an exception instead of returning nonsense.Is there anyway to make String.Format throw an exception if the object does not match what the format string is expecting?

Format String To Pass To String.Format That Would "move" The Decimal Point?
Aug 26, 2010So I need a format string to pass to String.Format that would "move" the decimal point.I can't perform any math operations before doing the String.Format, so it has to work right off the bat.Basically I'm emulating a formatting string from a proprietary server. In it if I say:
"MR2"
for the value:
12345
The result is:
123.45
I'm close with this, but it's not spot on:
String.Format("{0:#0.##}", 12345)
an extra, but not necessary... there is also MR2Z, which moves the decimal 2 left, but if the value is 0 "" is returned.

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?
Apr 5, 2011I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results.
