Calculation Error Output - Conversions Between Decimal,string ?
Mar 29, 2010
I am struggling to get this to output calculations correctly. Have I properly made my conversions between decimal,string and so forth. Is that the only reason that a calculation would not produce the right result or is there another reason? I have negative total results for output when they should be positive.
Dim decAmount As Decimal
Dim decInterestRate As Decimal
Dim mdecFutureValue As Decimal

I've searched for the solution for this however 'answers'i've found have perhaps been a little more than I've needed. basically i have 2 textboxes on my form, 'textbox1' is populated by a value from a database, say.. 200.00 on form load. 'textbox2' needs to accept a users value (say 50.00) and then add/subtract that from the value in 'textbox1' when the form's refreshed/submitted/whatever
whats the syntax involved in this process, i've seen efforts involving parse, 'Cint' etc but need to check there isn't some ridiculously easy way of doing this..

I have an error in my VB.net program - I have tried various casts etc but it just will not resolve the issue - so reluctantly I post it here to see if anyone else has a similar problem.

End Function

What is the cleanest, most readable way to String.Format a decimal with the following criteria
start with a sign symbol (+ or -)
a fixed number of fraction digits
no decimal separator
right aligned
pre-padded with "0"'s

When I have Option Strict ON in my project, the IDE tells me that "Option Strict On disallows implicit conversions from 'System.Data.ParameterDirection' to 'String'." How can this be, since I'm using their built-in enumeration for the SqlParameter direction.

The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.

I 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. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

I'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

im calculating fare amount from 2 masktextbox mtxA and mtxB, i use the format 0000.00 ,, i was able to convert all prompt char values from mtxA and turned them into really zero but however it doesnt do the same on mtxb, though ive used similar code.. so my flow should be: whatever i values i put on mtxA.. on its textchange,its current value should be also put to mtxB plus an additional of 200.00
as an example : if i put on mtxA = 0030.00
mtxB = 0230.00 should be the display
but what is shows on me is mtxB = 2300.00 and also if i save it on the database .00 is not added,.....im tired fixing this so i try to use textbox instead of maskdtextbox, what i did is put lots of conditions and function on keypress to have the same format 0000.00 but i failed because everything on my code mess up whenever the user tried to edit the text according to textbox current position..check textbox.text current length from 0 to before the cursor location...but i dont know what code i should use to get the length..

First: Ok so I'm trying to do a project in my beginning VB .Net class. We are supposed to be taking information from 5 different sections of a form and store them into an array and then call upon them later. We have Name, Address, City,State, and Zip. How would I go about saving the information into an array and then calling upon it later through File IO?
Second: I'm having a problem converting my string into a decimal. Whenever I calculate the price of the order I get 3-4 decimal places. Here is a little snippet of my code for the this:

I have dimmed pricewithout tax as a decimal and stateselect as a string. The stateselect is based off a drop down list.
