I'm a college student, working on a small project, and I'm having some trouble understanding the Round command on VB. The project is very simple and straight forward, just a simple Bail Bonds program to calculate the bail plus a 10% fee. However, i want to integrate a kind of "promotion", where for every $1000 of the bail cost, $5 would be deducted. I know the formula for this, which is reasonable simple, i just need to know how to round the Bail variable to the nearest 1000 so i can do this calculation.

I haven't used VBA in a very very long time. So, go easy on me. I'm trying to do an IF THEN ELSE function where whatever the pVal cell says, Excel will input the correct currency value in the next cell. I have the cell format in the Excel workbook set to currency with 2 decimal places. However, when I add the UDF, it rounds up! I basically copied and pasted this code from an online website, but theirs did not have any decimals. I've tried calcvalue = Format("48.95","Currency") but it still rounds. I'm sure I'm leaving out something simple. Here's my function formula so far.

I have a series of text boxes with numbers. They are an array called txtBF(0 to 16). I am trying to take the value that is to be displayed in the text box and make it have only one decimal place. I have tried using this code below but I keep getting an error message Run Time Error 13: Type Mismatch.
txtBF(11).text = Round(txtBF(11).text, 1)
and I have also tried this
txtBF(11).text = Math.Round(txtBF(11).text, 1)

With the application i'm building i have to do some calculating, ive so far not had to do anything like this so i could use some pointers. Here's the simplist of calculation i have to do, if i could get some help pointing me in the right direction i could probabaly figure the rest out.
It would be Box1value * box2value / 144 = box3 But if box 3 returns a value of less than 2.5 it rounds up. The rounding function is very important to subsequent calculations i will have to make.
So the this simple form would work where the user inputs a number into box one and two and the calulation appears in box 3. Attached is a mockup of the form design.

how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.

I'm using VB08. I've populated a listbox with numbers and I want to add all those numbers together and display the result in a Label. I've heard about using parse but I don't understand exactly how it works.
This is the code that I have that i think should work.
Dim lblTotal As Decimal
Dim sum As Double
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Double.Parse(decAdded)
Next
lblTotal = FormatCurrency(sum)
When I run it, nothing happens. My "For Each" statement I'm not sure if it's doing what I think it's doing. I can't believe I spent 6 hours banging my head against the wall but I finally got it figured out.
This is my revised code:
Dim sum As Decimal
For Each decAdded As Decimal In Me.lstRunningTotal.Items
sum += Decimal.Parse(decAdded)
Next
lbl_Total.Text = sum
Just some suttle changes made the difference

Im trying to write a program that will do:
1.The average of the four numbers. This answer will be placed into a text box reserved for that value. This text box cannot be changed by the user.
2.The maximum and minimum values. These will be denoted by changing the color of the largest number green and the smallest number red.
3.The range of the numbers. The range is defined as the difference between the largest and smallest numbers. The range will be placed into its own text box, labeled as such. This text box cannot be changed by the user."

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

I just D/L VB express 8, and I'm trying to learn how to use it. what I'm trying to do is write some code that:takes a number into a text box (textbox1.text)do some simple calculations with that number when I press a button (button1)display the results in a second text box 9textbox2.textThe first problem I am having:The numbers are in the "milli" range, meaning to the power of negative three, so 10^-3 = 0.01 I do not want to enter 10^-3 or any other exponent into the textbox, I am simply entering in 10 because all my units will be in milli. I've tried using exponent and scientific notation but it doesn't calculate correctly. I've done a "work around" to get it to do what I want, but there has to be a simpler way to achieve the above results without. for example, the user enters 10 into the textbox, the button multiplies 10^-3 *30, as a crude example, and stroes that value (say, B=10^-3*30) and B is DIM B as Double.
Problem number two:Error checking. I need to validate that only numbers can be entered into the textbox, or else the program will display an error message (messagebox). I can achieve this to some degree with sample code from here and other places, but, some of the code does not take into account that some numbers have decimal places (I have foud code that does, and it does work), but if a users enters, say the letter "E", it crashes the program. If the user enters "10.3Z", it crashes the program. I cannot seem to code for the last case, a mixture of numbers and letters to get an error message box.

Im just trying to get a simple multi line label box counting numbers using vbCrLf.
Dim startNumber As Integer
For startNumber = 1 To 4
lblCount.text = "Number = " & startNumber & vbCrLf
Next startNumber
I just want something to display like this in a multi line label, not a textbox:
Number = 1
Number = 2
Number = 3
Number = 4
But... I keep getting something like:
Number = 4
I already turned auto size off and expanded the label.

i'm new to the VB programing world, actually to programming world in general, so before i start i have a question. I've heard that to run programs created in VB you need to have NET Framework on your comp, is this true?Cause i found somewhere on the web that you have a exe in your Debugging folder, and i tried running it on my friends comp which is without framework and it worked. Don't know if this was some error or something, and if there will be problems if i run them like this, so i wanted to ask professionals,

I am trying to make an application using vb2008, and I'm facing a problem. I have a command button, and I want it to generate a new groupbox each time it's clicked. So here's the problem: when the user clicks the button, the previous groupbox disappears, which is sth I don't want to happen. Also, I wonder how I can use each of the controls included in the groupbox, while I can't name them or something...
