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..

I m using a reportviewer in vs2008 with vb. I have a database field(datatype decimal) on my reportviewer. I added a textbox from toolbox into the reportviewer. Now i want to show currency text into textbox equivalent to that database field value. In short i want to convert 155.75 into "one hunded fifty five dollars and seventy five cents". Here 155.75 is decimal value from database field and one hunded fifty five dollars and seventy five cents" the converted textbox value. I have a private function in my module for conversion. but i m not getting idea how to implement that function on reportviewer or how to call that function to convert as i want.

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 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

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.

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]

As the title says I have a form with many databound textboxes. some of these boxes have data in them and some are empty. I need to add them altogether, so far all of the conversion methods I have tried err out when they run into an empty string, except Val, but then Val won't handle the string with a $ in it. I've tried decimal.parse which handles the $ but not the empty string. So I seem to be in circle that I can't get out of.

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?

I was given a school project in which I have to make a program that converts numbers between binary,decimal,octal and hexadecimal systems. I have figured out how to make a function to convert binary number to decimal number [code]With this code,a user can enter a number that isn't binary,and program will calculate it. How can I make that program doesn't calculate those numbers or doesn't accept anything else than 0 or 1? This is needed for other cases like octal and hexadecimal system.

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.

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"

I am working on a VB application in Visual Studio 2005. I have a number of fields where the user needs to enter currency amounts. I am using a MaskedTextBox with the following currency mask. msktxtAssessedVal.Mask = "$ #######.99"
The problem that I am having is that when the users type in the value, the cursor always starts at the leftmost position and appears to force that many digits. The typical data values can vary anywhere between 9,999,999.99 and 20,000.00. If the users do NOT have a value that has 7 digits left of the decimal point, they need to move the cursor to the correct position before they start typing in the value. These users are used to quickly typing in their data, then tabbing to the next field so the current behavior is not acceptable.
Does anyone know if there is a way for the maskedtextbox or any text control to detect where the user types the decimal and format the data accordingly?
