VS 2008 - Variable Divider Ex. - Numbers From My Textboxes In The Range Of 20 To 60
Mar 4, 2010
I need a variable divider ex. i have numbers from my textboxes in the range of 20 to 60 i want a divider that will divide them in a range of 2 to 6 so if the number is the lowest 20 the divider will divide him with the lowest of his range number 2 if the number is 40 the divider will divide him with the number 4 if the number will be 45 the divider will divide 4,5 and so on a variable divider.
I have 5 columns of 11 textboxes each on my form the textboxes are generated with this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'column 1 textboxes
i need a code to generate all the possible combination of the numbers a user types into the textboxes i have two images (Panel3: the textboxes where added during design time) image2: the textboex were added using the code i gave about
generate all the possible combinations of numbers typed into the textboxes (Example see panel3.jpg image),
The user will type in the desired unique numbers into the textboxes without repetition (Please see the image i did not repeat any number, so can the code detect when a number have been typed twice?) Else when running the program i will be carefull not typing two numbers twice, but its adviceable to detect when a number is typed more than once.
Then the amount of unique number the user will type or supply to the desired textboxes does not matter here and as you can see in the image the amount of numbers in each column is not the same ie it may or may not be same amount (but number must be unique. Please try and see if it can be done to prompt user to enter the amount of numbers to supply in each column)
Then After supplying the numbers just like the one in Image, The button Click will generate all the Possible Combinations of the all the numbers typed into the textboxes in the columns.. Then After generating the combinations in the Listbox, the next Button will be able to delete them from the Universal 90c5 just like the former.
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."
Im using visual studio 2008 and it has to be written in VB
i have one more issues, and hope is the last for now. How can I limit a textboxe's input to only numerical with certain range of values (eg -10 to 10) and with that happening while I type in the values?
I have six textboxes, and upon button press it randomly generates six numbers, one in eact text box e.g.      ..i create another six textboxes and at the same time allocate these numbers in ascending/descending numbers.I am not looking for any codes whatsoever, as i love the challenge of VB.Net.
Write a program that will allow the user to be able to choose whether they want to add up a range of numbers in one of three different ways. 1) even numbers 2) odd numbers, or 3) consecutive integers. Use buttons for user choices.
Instead of limiting the user to just adding up these numbers you will also supply an Average Button that will show the average of the numbers rather than just the sum. Only the result that they have selected should be visible.
The program should look similar to the program below:
This is the program I was asked to make.
my code soo far is.....
I couldn't figure out the formula to use for this but I assume its the same for each part of the program just with a little change.
Say I am pulling the following table, I would then like to select an ID randomly. I understand how to select a random number using a Randomize() call followed by the relevant syntax but I want to pre-define the range.
i.e. Table Data ID | Name 4345 Mike 3456 Lee 4567 John
There will be many more names but for this example you could use 3 or 4 etc..
I'm making a program as part of a college assignment that requires my to add up the contents of an array. Now the array has 20 places, and the only method I know of atm is:a + b + c + d + e etc...They are all different numbers so I can't just do a * 20, I need a more code efficient way of adding all these numbers up, is this possible?
I have two user inputs (as textboxes) for two numbers I'm looking to check for all the prime numbers with the range of those two numbers and display them within a multiline textbox, however my code returns nothing but zeros, and I have seen easier ways to do it without functions but I am curious as to how to go about calculating primes within the function.[code]...
I am trying to create a form that allows users to input two numbers a high bound and a low bound then when you click the calculate button it determines all the primes within the range and displays those numbers within a multi-line text box. It seems I have everything working except how to display the prime numbers, the result from the following code displays nothing but zeros so I suspect that the range is not being saved somehow? I have asked this on other sites and people just give me completely different code or their own, can anyone help me with this specific code without changing the underlying code, I have a feeling I might be missing a variable or I am calling the function incorrectly.[code]
I have to define a name for a varying-length column of cells. The name is used later to define the range for a Data Validation List. I just cannot figure out (and the Help Function isn't assisting) how to define the Name, say "DropOrdNum" using a variable as the address for the last cell in the range. It is easy to define a name for "O13:O2000" - no problem, but then I have a whole lot of blanks in my drop-down list. But how do I define a name for "O13:LastCell", by making "LastCell" the Range Variable (am I correct in this) for the address of the last cell in the active range and then defining the name "DropOrdNum" as being the range "O13" to either "O(the row number of the last cell)" or "LastCell", being the address of the last cell in the active range, which varies by the hour?
i have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?
[URL] I'm trying to do an exercise on that website but it doesn't show the answers to the exercises..
I've gotten everything to work except one thing. I can't get the right numbers inside the textboxes! I've been sitting here for like an hour trying to use a case statement.. it didn't work for me so I tried to use if then statements and I still couldn't get it to work!
Here's my code for that part: Ignore the second if I was desperate xD Private Sub btnSubmit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
And for the Case statements, if I wanted to use it for a range of numbers, do I write "Case 1 To 10" and that's numbers between 1 and 10? Is that right?
So I created a loop that collects data from the user that runs for a time dictated by the user. It then stores all the data in excel and outputs a graph.The problem I am having is that I cant seem to figure out a way to set the range of the graph for the points taken.since it runs on a loop i have i = i + 1.where the the output into the excel file sequentially writes to the next cell [code]which doesnt seem to work like I would have hoped.Also, there is one other thing that my program keeps doing that I cant seem to figure out.One of the outputs to the excel file is decimal number, it shows perfectly in the textbox, but when I export it to excel it rounds it to the nearest whole number.[code]
I have two functions to find the high and low numbers from 5 different textboxes. I want the high in one label (which I have) an the low in another. I cannot seem to get the low number to be anything other than 0. Here is the code:
I want to make a program like this but not with random numbers ! I want it with A list from ".txt" or "from number 1 to number 999999999"
Public Class Form1 Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click Timer1.Start() End Sub Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click Timer1.Stop() [Code] .....
I have made my calculator and it has 2 textboxes where the 2 numbers (or values go for addition and subtraction) are input and a label where the answer appears. There is other things on the page such as quit, clear etc thats all done but i have one query. I noticed while testing a problem occurs when only one number or value is put into a textbox and a command is hit. For example. one textbox (txtnumber1) has one number in it then i hit multiply and it says the error of course because its not programmed to deal with this (or divide by 0 of course) so i was wondering how i could make so when this happens a MsgBox appears saying a value must be in both boxes or when divded by zero is says something similar.
The line of code:
Private Sub blah blah blah...
If txtnumber1.Text = False Then MsgBox("Please Input Valid Value")
I'm developing an app that should allow the client to add several content sections to a page (in tabs). However I haven't found a way to easily create a form for editing the tabs.Assume for now that a tab just contains a title. I have a form that adds a tab, that's simple. But I also want a form that displays a text input for each tab and allows the titles to be edited and saved. I'm struggling with two main concepts:How to dynamically display the fields after grabbing the tab data from the database (each tab has its own row in the table).How to loop through the submitted data and update each tab in the database.How to select a particular text field from the number (e.g. given "1", how to select the element with ID "TabTitle_ 1".[code]I thought something like TabTitle would be acceptable and allow for easy looping (as it does in PHP) but it's "not a valid identifier" apparently.It's very possible I have the approach completely on its head.
How can I read data from textbox1 to....n using cycles? Something like this: 1. For n=1 to 50 2. text=textbox_n.text 3. Output=output+text 4. Next 5. Msgbox(output) The question is in line 2. Syntax "textbox_n.text" is not right. How is it possible to read from textboxes using cycle and variable n?
I have a windows form on which there is a textbox and a command button. When user inputs an integer in the textbox and clicks on the button, the userform grows and adds that many number of comboboxes and textboxes in a panel.
how to add variable number of comboboxes and textboxes at run time.
I know how to declare a variable, a function, to write a string of characters or numbers (I still looking in tutorials and depict from there what i need to know) but...WHAT I DONT KNOW is how to USE them? At "what" or "how" are you thinking when you make a program? I try for SOME LOooNG TIME to understand but I think im too stupid to understand from pages on the net (or i dont find THAT tutorial who can explain right for me).I try a lot of programing languages starting with pascal,c,c++,darkbasic,alice, Visual-c,c#,c++,basic,php,even assembler, some programing zones in Excel and Word but from all of this i cant manage to understand the life behind the words.
I am using the following code in the Load method of a VB form to generate random numbers in the range 1 to 8. Without fail after enough loops the range is exceeded and 9 is the random number returned every time. The line using the Rnd function is from: Rnd Function (Visual Basic)
