VS 2010 - Accepting Upper And Lower Case Letters?

Aug 12, 2011

I'm new to VB and I'm trying to get this app to recognize that a "C" is the same as "c" but for some reason its not recognizing it. Its seeing the lower case letters as 10%.

Here is the code I currently have...
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click
Dim subtotal As Decimal = CDec(txtSubtotal.Text)
Dim discountPercent As Decimal

Any Type Of Case ( Not Just Upper Or Lower)

Apr 22, 2012

Here is what ive got:
a1 = inputbox("YES or NO")
If a1 = "YES" Or a1 = "yes" Then

That's all we need to know. There are a variety of choices people could put in the input box:
YES
YEs
YeS
yES
yes
Yes
yEs
yeS
I don't want to do if a1 = "YES" or a1 = "YEs" or ... etc

Is there some way I can do:
if a1 = allcase."YES" then
Or something along the lines of that?

Keypress Upper / Lower Case

Mar 8, 2012

I'm currently using this bit of code to let only Y, N, and Backspace be typed in my textbox: [code] My problem is that when I debug, the "n" has to be capitalized in order for it to show up in my textbox and the "y" has to be lower cased. Is there anyway that I can bypass this to where it doesn't matter wether or not it is upper or lower case?

Lamba Expression To Select All Values Between Lower And Upper

Nov 19, 2010

lambda - vb.net lamba expression to select all values between lower and upper values plus the next lower and upper value. I need some help with a lamda expression to get a subset of range of values. I have a lower and upper value, and getting everything between them seems easy enough, but I also need the next lower and higher value to be included. I can do each of these separately, but would like to do it in one shot if possible.

The range I need the subset from has 150 values. A small example would look like:
{8.206,8.206,8.201,8.196,8.193,8.192,8.189,8.174,8.171,8.171,8.166,8.163,8.157,8.154,8.153,8.14,8.131}

My lower value is: 8.16
My upper value is: 8.17

I need to get back: {8.171,8.171,8.166,8.163,8.157}

Dots More Dense At Upper Or Lower Edge Of Curve (searching Algorithm)?

Mar 2, 2011

This question may be off-topic. If it should be posted in another place (even on another board) For some given curves (see sample below) I have to quantify whether the red dots in some regions of the curve are more dense at the upper or lower edge of the curve. Which algorithm might be adequate to perform this task? The curves are constructed from measurements. (No mathematical formula behind it.) Every data point has two dimensions: A value in the range 4000-7000 and a second value 0-255.

Forcing Upper Case On Text Fields?

Aug 22, 2009

I have a series of text fields on a simple form (inside a group box) I would like to enforce all the text be upper case upon submission to the database. I know I can use the Ucase command. The question is implementation. How can I very efficiently force all the field values to upper case vs. say doing Ucase(TextBox1), Ucase(TextBox2).... ( I have 12 fields in this case) Is there a way to treat the text boxes as a collection and do it in one shot? Just trying to be very efficient and create clean, tight code even on such a simple thing.

Create A Random Number Generator That Iterates Through A Series Of Number Between An Upper And Lower Bound?

Jun 24, 2010

i wanted to create a random number generator that iterates through a series of number between an upper and lower bound. say between 1 and 100. Basically I want the number generator to pick the numbers randomly and then display them until all 100 numbers are picked without any duplicates. so thats easy I can code that. But what I don't know is how to show those numbers in the order they are generated on a windows form. So i have basically a variable that I will let be changed 100 times (or however many times I want, I don't want their to be a size constraint just using 100 as an example) and each time the number is generated I want it displayed on screen (in a list or something not sure what. Hopefully some type of scrollable list) and each successive number also to be displayed in same format beneath it so that I can see the list in its entirety. What type of form control do i use for that? I could do messagebox.show for each iteration but then user is required to hit ok after each iteration and that would obviously be a bad idea if user selected a large number to work through. Anyways, code isn't exactly necessary just point me in the right direction, i.e.what control (if any) to use.how to format the change in data?

Receive Upper Bound And Lower Bound Of A Range

Sep 20, 2010

Is there anyone who can tell me the code for the below? Receive a lower bound and an upper bound of a range. Also receive a number of random numbers to generate. You must validate

1) the numbers are integers
2) the lower bound is less than or equal to the upper bound
3) the number to generate is positive (i.e., > 0).

Generate this many numbers in the specified range and keep track of how many of each are generated in an array of counters. Once all the numbers have been generated, display in a List Box the number, the raw count data, and the percentage of how many times the number was generated displayed with two decimal places of precision.

Specific Reason Camel Casing Examples Often Start With A Lower Case Letter?

Jan 14, 2010

Is there any specific reason why camel casing examples often start with a lower case letter?

E.G:Dim btnSave As New Button
'as compared to.>>
Dim BtnSave As New Button

Is it to make a distinction between the ( object / variable ) and its TYPE?

Why then does the IDE not add items starting with a lower case letter if lowercase initial lettering is more common or more accepted?

VS 2010 - VB 2010 - Automation - Function For Accepting The Keystrokes

Sep 13, 2011

I am creating a VB 2010 program that lets your select the program(s) you want to install (chkbox) and hit run. Then have it launch the installer ( the file is across the server) and accept the predefined keystrokes to proceed through the installation process. Afterwards, it starts the next install. Below is the code that I have. What i cant get to function is the unit accepting the keystrokes, its almost as if it wont take focus ( even when i have used Appactivate and threading.thread.sleep). I have even gone so far as to identify it as a process to manipulate the thread. To be honest, i'm at a loss and need any help at all. The final sub that contains "btntest" is where I am at currently in my attempts. [Code]
