As a beginner I am unable to find how to diplay decimal in my DataGridView.
I am using VB 2010 And using access 2010, I designed my database and set the following
Set Data type to Number. Field Size to Decimal Format to 0.0 Decimal Places to 2
When the DataGridView is diplayed on the form, all the decimal's are rounded to integers.

View 2 RepliesI've seen this question posted a few times but no good results. I'm simply loading a dataset from access that happens to have a bitmap stored in a field. I have a listview with a list of CD's by Album/Artist, when I click on one of the CD's I want detailed info to populate below, including a pic box with the stored bitmap. Everything works fine except the pic box. [code]...

I want to understand what I'm learning so it will stick. What is Ubound? I realize I need to rewrite some of this to fit to what I'm trying to accomplish, but I want to understand it first. This is not in the book thus far. The codes I have found were sorry...horrible...I want to learn to write better with less words if possible?

I'm fairly certain I'm missing the obvious, but I'm trying to force a datagridview cell to format the contents of a cell to two decimal places when the value is changed e.g. the user enters 20 in a cell and it's formatted to 20.00 when the cell is moved away from.

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 .
View 2 RepliesHow 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

Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?
1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:
Variable 123.34D ----> textBox 123,34 or 123.34 -----> variable 123.34D
Is there a way in VB .NET to have a decimal variable with 40 decimal places?
View 3 RepliesMaybe 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"

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

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..

View 4 RepliesI 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.

Currency = txtCurrency.Text
Exchange = txtExchange.Text
Amount = txtAmount.Text
Result = Amount * Exchange
