Converting String Into A Decimal?

Mar 17, 2009

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:

[code]...

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

Converting A Decimal To An Empty String

Oct 31, 2011

I'm sure this is simple to do but I'm struggling to get this work, I've tried using convert.tostring, decimal.tostring, ctype(object, type) and cstr(object) but without success. I guess I'm trying to change the decial object to a string object and then assign it a value of empty string but always get type mismatch error.[code]

Forms :: Currency Converting A String Value To Decimal For Calculation?

Jun 7, 2011

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..

Asp.net - Converting Decimal In A Label To An Integer?

Mar 28, 2011

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?

VS 2008 Converting Hexadecimal To Decimal

Jul 7, 2009

This program, it reads in a file, and displays it in hexadecimal, like using a hex editor. It then goes to compare the strings and whatnot, and display certain values. During the program, there is a time where I need to display a set of offsets as decimal because that is the way that it is shown regularly.

Taking the two specific offsets and displaying them in hex ends up giving me something like "3039" or "000A", which should respectively convert to 12345 or 00010. This "ID" that I am converting, can be 00000 to 65535, which in hex is 0000 to FFFF. The current method I was given only works if the value is less than 512 or something like that.

Converting Multi-byte Hex Values To Decimal?

Apr 25, 2011

How would I convert the two individual byte values (in hex) to a decimal value representing the concatenated hex values? For example, if I have the

Dim byte1 As Byte = &H99
Dim byte2 As Byte = &H99

' I want the decimal representation of the hex value "9999" ' (byte1.ToString + byte2.ToString) which should be "39321" Currently I use the following code:

Dim decVal as integer
decVal = Val("&H" + Hex$(byte1).ToString + Hex$(byte2).ToString)

However, when I use this, the value (decVal) comes out to "-26215"

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?

Apr 5, 2011

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?
