Change Decimal To A Comma When Hitting Decimal Key On Numpad Only
Jan 17, 2011
My user requests to change the . on the numpad to a when entering text in a multiline textbox.So I was thinking about the KeyDown event.To determine if the numpad . was pressed I can do something like this [code]But now how do I change the returned charachter as a , ? All e.Key... properties are ReadOnly. The KeyPress events let me change this by providing e.KeyChar, but in that event I can't check for the numpad .
I'm having some trouble converting a double to a string.I have a double value, like 43.64 and I need a string like this: "43.64"If I try to convert the double to a string I always get "43,64" what doesn't work for me..
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
[code]....
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..
I have Dim InputVariable as Double InputVariable = Val(InputBox1.Text)
Now I am in Germany and we enter decimal values with a comma, like 53,52. When I enter this into my InputBox, the InputVariable shows only 53 after Val(). This is caused by entering the comma as decimal separator instead of the dot. When i enter it with a dot, like 53.52, the variable has the correct value. Is there a workaround, so that i can use the Val() function together with german input of comma decimal symbol and my variable gets assigned the correct decimal value instead of cutting it off?
My chemistry calculations program, written in Visual Studio 2008, VB.Net (Win XP), gives completely wrong results when a Comma is used as Decimal Symbol.The calculations are only correct with a Dot (.) as Decimal Symbol.How can I make the calculation results independent of the Decimal Symbol? (Dot or Comma)?(For example Excel calculates correctly with a Dot or Comma as Decimal Symbol)I have found an old thread adressing the same problem, but no simple and easy solution was given.
For some time I try to get the comma instead of the decimal point, but the labels I use won't display a comma. For some reason I don't understand, the msgbox() does the trick, but is useless in my application. This is my last desperate piece of code I tried but it also failed.
Expresserprijs = EuropluscolNL(ArrayCol, 2) - EuropluscolNL(ArrayCol, 1) ' All above are "Doubles" and are fed with data like 21,45 (with comma's that is) Decimaalteken = Expresserprijs ' Decimaalteken is a string MsgBox(Decimaalteken) [Code] .....
Is there a format string to format a decimal to 000000000,00. So first 9 digits, right padded with zeros if needed; a comma as fraction separator and two fraction digits. 0 => 00000000,00 12 => 00000012,00 987456,456 => 000987456,46 So something like myDecimal.ToString("D9") together with .ToString("F2").
In VB.Net, is there a way of auto-detecting the culture of a string representation of a number? I'll explain the situation:Our asp.net web site receives xml data feeds for boat data. Most of the time, the number format for the prices use either a simple non-formatted integer e.g. "999000". That's easy for us to process.Occaisionally, there are commas for thousands separators and periods for the decimal point. Also, that's fine as our data import understands this. Example "999,000.00".We're starting to get some data from France where some of the prices have been entered with the periods and thousands separators the other way around as that's the way it's done in many European countries. E.g. "999.000,00". This is where our system would interpret that as nine hundred and ninety nine pounds instead of the nine hundred and ninety nine thousand pounds that was intended.
After converting all degrees-->decimal, and decimal-->hours, how can i use Tan, Cos and Sin formula in vb.net? I want the user must enter an input (which it is a coordinat-->i already convert the degrees-->decimal value as suggested by stanav and paul.
The questions like this (i only calculate on paper but dont know how to implement in code):
Input user need to enter: -latitude local (e.g. 1.4875) -longitude local (e.g. 103.3883333)
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
Maybe this is just a really basic question that everyone knows the answer to, and is why I couldn't find the answer. What I want to do is pretty simple. I want to declare a custom type that's just like a Single, except when you access the value, you get the value rounded to the second or third decimal place. Something like this:
Dim MyNumer as TwoDecimalNumber MyNumer = 1.124 Msgbox(MyNumber) 'This would pop up a box showing "1.12"
In window textbox, I'd like to just allow 2 decimal points only. I could set text box only numeric but don't know how to limit 2 decimal points.[code]...
I have a string which looks like this 512.3 is there a way to add a trailing zero so it looks like this 512.30 Just to clarify (sorry I didn't know there where different ways etc.) My string is an amount which is passed so changes all the time I only need the trailing zero on amounts like 512.3, 512.4,512.5 etc. as some of my amounts will pass values like 512.33 and 512.44 and so on
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 am trying to write a code for a curency convertor.The result from multiplying the amount by the exchange has to be to 2 decimal places in order to convert it into Pounds and Pence.
Dim Currency As String Dim Exchange As Decimal Dim Amount As Integer Dim Result As Decimal Currency = txtCurrency.Text Exchange = txtExchange.Text Amount = txtAmount.Text Result = Amount * Exchange lblOutputMessage.Text = Result
Mod Edit: When you are posting code please use code tags like this.
